Management Information Systems
UNIT I
Lesson 1 – Introduction to Information Systems
Learning Objectives
• To explain how IT impacts upon organisations.

• To analyse the necessity for IS in the management of modern, and increasingly
global, organisations.
• To recognise that IT professionals need to understand how an organisation operates in
order to effectively apply technology to make the organisation more efficient and
competitive.
• To explain how an organisation must change in order to successfully capitalise on the
use of IS and the consequent impact on organisational structure and employees.
• To identify how the benefits of using IS may be measured and assessed, and contrast
with existing practice.
1.1 Introduction
As a consumer, you have instant access to millions of pieces of data. With a few
clicks of the mouse button, you can find anything from current stock prices and video clips of
current movies. You can get product descriptions, pictures, and prices from thousands of
companies across India and around the world. Trying to sell services and products? You can
purchase demographic, economic, consumer buying pattern, and market-analysis data. Your
firm will have internal financial, marketing, production, and employee data for past years.
This tremendous amount of data provides opportunities to managers and consumers who
know how to obtain it and analyze it to make better decisions.
The speed with which Information Technology (IT) and Information Systems (IS) are
changing our lives is amazing. Only 50 years ago communication was almost limited to the
telephone, the first word processors came out in the mid-sixties and the fax entered our
offices in the 1970's. Today information systems are everywhere; from supermarkets to
airline reservations, libraries and banking operations they have become part of our daily
lives.
The first step in learning how to apply information technology to solve problems is to
get a broader picture of what is meant by the term information system. You probably have
some experience with using computers and various software packages. Yet, computers are
only one component of an information system. A computer information system (CIS)
consists of related components like hardware, software, people, procedures, and collections
of data. The term information technology (IT) represents the various types of hardware and
software used in an information system, including computers and networking equipment. The
goal of Information System is to enable managers to make better decisions by providing
quality information.
The physical equipment used in computing is called hardware. The set of
instructions that controls the hardware is known as software. In the early days of computers,
the people directly involved in are tended to be programmers, design analysts, and a few
external users. Today, almost everyone in the firm is involved with the information system.
Procedures are instructions that help people use the systems. They include items such as user
manuals, documentation, and procedures to ensure that backups are made regularly. Data-
bases are collections of related data that can be retrieved easily and processed by the com-
puters. As you will see in the cases throughout our book, all of these components are vital to

creating an effective information system.

To create an effective information system, you need to do more than simply purchase
the various components. Quality is an important issue in business today, particularly as it
relates to information systems. The quality of an information system is measured by its
ability to provide exactly the information needed by managers in a timely manner. The
information must be accurate and up-to-date. Users should be able to receive the information
in a variety of formats: tables of data, graphs, summary statistics, or even pictures or sound:
Users have different perspectives and different requirements, and a good information system
must have the flexibility to present information in diverse forms for each user.
1.2 Data, Information, Knowledge, and Wisdom

Let us consider the case of a retail store that is trying to increase sales. Some of the
data available includes sales levels for the last 36 months, advertising expenses, and
customer comments from surveys. By itself, this data may be interesting, but it must be
organized and analyzed to be useful in making a decision. For example, a manager might use
economic and marketing models to forecast patterns and determine relationships among
various advertising expenses and sales.
The resulting information (presented in equations, charts, and tables) would clarify
relationships among the data and would be used to decide how to proceed It requires
knowledge to determine how to analyze data and make decisions.
Education and experience create knowledge in humans. A manager learns which data
to collect, the proper models to apply, and ways to analyze results for making better
decisions. In some cases, this knowledge can be transferred to specialized computer programs
(expert systems).
Wisdom is more difficult to define but represents the ability to learn from experience
and adapt to changing conditions. In this example, wisdom would enable a manager to spot
trends, identify potential problems, and develop new techniques to analyze the data.
1.3 Characteristics of Information
Now, let us discuss about the characteristics of good information
• Timeliness: Information must reach the user in a timely manner, just when it is
needed; not too early, because by the time it is used it would be out-of-date; not too
late because the user will not be able to incorporate it into his/her decision-making.
• Appropriateness: Information must be relevant to the person who is using it. It must
be within the sphere of his/her activities so that it can be used to reduce uncertainty in
his/her decision-making.
• Accuracy: Accuracy costs. We don't always need 100% accurate information so long
as we know the degree of accuracy it represents (eg: + or - 5%). (Remember the value
of information).
• Conciseness: Information should always contain the minimum amount of detail that
is appropriate for the user. Too much detail causes information overload.
• Frequency: Frequency is related to timeliness. Too often the information presented is
linked to the calendar (end of the week, beginning of the month); its frequency should
be synchronized with the timing of the decision making of the user.
• Understandability: The format and presentation of information are very important.
Some people prefer tabular information, whereas others may need it in a graphical
form. Also the use of colors enhances the understandability of what is presented.

• Relevant: It pertains to the particular problem. What data is relevant depends on the
decision-making model used. E.g. university admissions officials may choose to
consider the results of some high-school test irrelevant, if they believe that it does
not improve the chances of some applicant later becoming a successful student.
• Complete: All the relevant parts are included. E.g. marketing data about household
incomes may lead to bad decisions, if not accompanied by consumption habits of
the target population.
• Current: Decisions are often based on the latest information available
• Economical: The costs of gathering information should be justified by the overall
benefits
1.5 What is a System?
A system is a group of interrelated components working together toward a common goal

by accepting inputs and producing outputs in an organized transformation process.
System will have the following basic interacting components (functions):
1. Input
2. Processing
3. Output
4. Feedback
5. Control
Let me explain the concept of system with an example. The following example will
give you better understanding about System.
Example: Sales Force Automation System (SFAS)
Suppose you are a regional manager who supervises 100 salespersons in Mumbai.
Your company's headquarters are located in Chennai. Your performance is daily evaluated
by the headquarters. You are compared with managers in other regions such as Delhi,
Kolkata etc. Your company publishes various books: encyclopedia, children's books, etc.
In short, the headquarters are not interested in each salesperson's performance. All
they care about is your performance, i.e. the regional sales results.
In order to save your job, you have to keep increasing sales. You have to motivate,
encourage, help, and discipline salespeople in Mumbai, if they perform, your job is secured.
If they don't perform, you will be fired.
Case 1
Each morning, you are supposed to submit a daily report to the headquarters. In the
report, you should include the total sales made in Mumbai yesterday, and sub-total of each
category (encyclopedia, children's books, etc.).
• At the end of each day, a salesperson submits his sales record to the Mumbai
regional office.
• The record is added to compute the total sales, and also summarized in terms
of book category.

• The total sales, and sub-total sales in terms of book category, are presented in
the daily report.
• Here, the daily record submission indicates "INPUT" in a system.
• Adding and summarizing indicates "PROCESSING" in a system.
• Reporting indicates "OUTPUT" in a system.
Case 2:
• In order to increase sales, you decided to implement a kind of performance

evaluation program, which is intended to motivate and discipline the
salespersons under your supervision.
• According to the program, if a salesperson makes daily sales greater than one
million, he will be awarded a gift certificate of Ebony Department Store. On
the other hand, if a salesperson makes daily sales less than one hundred
thousand rupees, he will be given a warning. If he makes a sales less than one
hundred thousand rupees two days in a row, a more serious warning letter will
be sent to him. If he makes sales less than one hundred thousand rupees three
days in a row, he will be fired.
• If you manually check all the sales records to comply the new performance
evaluation program, most of your time will be occupied by processing the data
and paperwork.
• In other words, you will have no time to do anything else: reading a new book,
learning new things, or playing golf, etc.
• In contrast, if you develop an information system that can carry out the
performance evaluation program, your life will be much easier. The program
is now automated with a computer-based information system.
• A major difference between this new system in Case 2 and the previous
system in Case 1 is that feedback and control functions are added to the new
information system.
1.6 What is an Information System?
Now, it is time to see the real meaning and concept of Information Systems. Too often
you hear someone say, "Oh yeah, I know how to use a computer. I can surf the Web with the
best of them and I can play Solitaire for hours. I'm really good at computers." Okay. So that
person can pound a keyboard, use a mouse at lightning speed, and has a list of favorite Web
sites a mile long. But the real question is "Is that person information literate?" Just because
you can pound the keyboard doesn't necessarily mean you can leverage the technology to
your advantage or the advantage of your organization. An organization can gather and keep
all the data on its customers that a hard drive can hold. You can get all the output reports that
one desk can physically hold. You can have the fastest Internet connection created to date.
But if the organization doesn't take advantage of customer data to create new opportunities,
then all it has is useless information. If the output report doesn't tell the management that it
has a serious problem on the factory floor, then all that's been accomplished is to kill a few
more trees. If you don't know how to analyze the information from a Web site to take
advantage of new sales leads, then what have you really done for yourself today?
Most of us think only of hardware and software when we think of an Information System.
There is another component of the triangle that should be considered, and that's the people
side, or "persware." Think of it this way:

PERSWARE
HARDWARE SOFWARE
We talk about the input, processing, output and feedback processes. Most important is
the feedback process; unfortunately it's the one most often overlooked. Just as in the triangle
above, the hardware (input and output) and the software (processing) receive the most
attention. With those two alone, you have computer literacy. But if you don't use the
"persware" side of the triangle to complete the feedback loop, you don't accomplish much.
Add the "persware" angle with good feedback and you have the beginnings of information
literacy.
An information system differs from other kinds of systems in that its objective is to
monitor/document the operations of some other system, which we can call a target system.
An information system cannot exist without such a target system. For example, production
activities would be the target system for a production scheduling system, human resources in
the business operations would be the target system of a human resource information system,
and so on. It is important to recognise that within a vending machine there is a
component/sub-system that can be considered an information system. In some sense, every
reactive system will have a subsystem that can be considered an information system whose
objective is to monitor and control such a reactive system.
A Business Perspective on Information Systems
Using feedback completes the information-processing loop. To be a good Information

Systems manager, however, you must bring into that loop far more than just the computer
data. For instance, your information system reports that you produced 100,000 units last week
with a "throwback" rate of 10%. The feedback loop tells you that the throwback rate has
fallen 2% in the last month. You can say, that's a pretty good improvement. So far, so good.
But if you put that information into a broader context, you're still costing the organization a
huge sum of money because each percentage point on the throwback rate averages Rs.10,000.
And when you bring in available external environmental information, your company is 5%
above the industry norm. Now that's information you can use - to your advantage or
disadvantage!
If you, as a manager, can then take other information from the internal and external
environments to come up with a solution to this problem, you can consider yourself
"information literate."
Organizations
Organizations are funny things. Each one tends to have its own individual personality
and yet share many things in common with other organizations. Look us at some of the
organizations you may be associated with - cricket team, fraternity, health club, or a child's
cricket team. See, organizations exist everywhere and each of them has its own structure, just

as workplace organizations have their own structure and personality to fit their needs, or in
some cases, habits.
A cricket team needs talented, well-trained players at different positions. Sometimes,

the success of the team depends on a good, well-informed coach or manager. So too with the
workplace organization. Business organizations need many kinds of players with various
talents, who are well-trained and well-informed, in order to succeed.
Every organization requires tools to help it succeed. If the baseball team uses bats that
are 25 years old against a team whose bats are 2 years old, they will have to work harder on
their own to make up for that disadvantage. If your child's cricket team uses balls with torn
seams, they're going to have a harder time hitting the ball into the boundaries. So if your
organization is using older equipment or uses it the wrong way, it just stands to reason it is
going to have a harder time beating the odds.
Management
Every good organization needs a good manager. Pretty simple, pretty reasonable.
Take professional cricket coaches. They don't actually play the game; they don't hit the run,
catch the ball for the wicket, or hang every decoration for the celebration party. They stay on
the sidelines during the game. Their real role is to develop the game plan by analyzing their
team's strengths and weaknesses. But that's not all; they also determine the competition's
strengths and weaknesses. Every good coach has a game plan before the team even comes out
of the dressing room. That plan may change as the game progresses, but coaches pretty much
know what they're going to do if they are losing or if they are winning. The same is true in
workplace organizations.

Business Perspective of Information Systems
Technology
Do you own a Digital Video Disk? Probably not, since it's only been on the market for
a short time. How old is your car or truck? Manufacturers are constantly offering us new
vehicles, yet we tend to upgrade only every few years. Your personal computer may be a year
old or three years old. Do you have the latest gadgets? Chances are you don't. Face it, you
just can't keep up with all the new stuff. No one can. Think about how hard, not to mention
expensive, it is for an individual to acquire everything introduced to the marketplace. Think
how difficult it is sometimes to learn how to use every feature of all those new products.

Now put those thoughts into a much larger context of an organization. Yes, it would
be nice if your company could purchase new computers every three months so you could
have the fastest and best technology on the market. But it can't. Not only is it expensive to
buy the hardware and the software, but the costs of installing, maintaining, updating,
integrating, and training must all be taken into account. We'll look at the hardware and
software sides of the Information Systems triangle in upcoming chapters, but it's important
that you understand now how difficult it is for an organization, large or small, to take
advantage of all the newest technology.
1.7 Components of an IS
In an organization, information systems consist of the following components. These

components will formulate a system, which will help us to gather the required
information for making decision in various levels of management. We will now see these
components in brief and discuss them in detail in the later lectures.
• Data - Input that the system takes to produce information

• Hardware - Computer itself and its peripheral equipment: input, output, storage
devices; includes data communication equipment
• Software - Sets of instructions that tell the computer how to input, process,
output and store data
• Communication networks - Hardware and software specializing in transmission
and reception of electronic data
• People - IS professionals and users who design, construct, operate and maintain
IS
• Procedures - Rules to process data, e.g. priorities in running different
applications, security measures, routines for malfunctioning IS, etc.
1.8 Information System Resources
Every Information System is equipped with the following resources. The goals of
information systems can be easily achieved by employing these resources to their optimum
level by keeping in view that the purpose of using IS in an organization.
• People Resources
o End users
o IS specialists
• Hardware Resources
o Machines
o Media
• Software Resources
o Program
Operating Systems (OS)
Examples: Windows, Unix, etc.
Application Software
Examples: Excel, Access, MS-Word, etc.
Application software that makes people buy computers
that can run the software.
Example 1: Lotus 1-2-3 (a spreadsheet program): In
early 1980s, personal computer market was dominated

by Apple (about 90% Apple, about 10 % IBM and its

compatibles); Lotus 1-2-3 was introduced and it could
be run on only IBM's MS-DOS operating system;
Companies all over the world were impressed with
Lotus 1-2-3, and wish to use the software. In order to
run the software, they had to purchase IBM PC or IBM
PC compatibles that run on MS-DOS.
Example 2: email system. To use an email system
(software), people buy computers.
o Procedures:
Operating instructions for the people who will use an information
system.
Examples: Instructions for filling out a paper form or using a software
package.
• Data Resources:
o Data vs. Information
1. Data:
Raw facts, observations, business transactions
Objective measurements of the attributes (characteristics) of
entities (people, places, things, events, etc.)
Attributes can be last name, first name, gender, etc. for
an entity of "people."
2. Information:
Data that have been converted into a meaningful and useful
context for specific end users.
Processed data placed in a context that gives it value for
specific end users.
1. Its form is aggregated, manipulated, and organized.
2. Its content is analyzed and evaluated.
3. It is placed in a proper context for a human user.
• Network Resources:
o Communications media
o Communications processors
o Network access & control software
1.9 Why Information Systems?
Ask managers to describe their most important resources and they'll list money,
equipment, materials, and people - not necessarily in that order. It's very unusual for
managers to consider information an important resource and yet it is. This chapter will help
explain why you need to manage this resource as closely as any other in your organization.
The Competitive Business Environment
For many years computer technology was relegated to the backrooms or basements of
a corporation. Only the "techies" worried about it and were often the only ones who really
knew how it all worked. Now computers are all over the organization - one on every desk. It's
not enough for you to know how to pound a keyboard or click a mouse. It is not even enough
for you to know how to surf the Web. Now every employee, including you, must know how

to take advantage of Information Systems to improve your organization and to leverage the
available information into a competitive advantage for your company.
Emergence of the Global Economy
Next time you purchase a product, any product, look at the fine print and see where
it's made. It could be China, or the Philippines, or India, or even in the USA. You can
disagree with the many manufacturing jobs that are being moved from the U.S. to foreign
countries. But look at the vast number of jobs that are being created in this country. Maybe
they aren't the traditional factory jobs we're used to. In fact, many of our new jobs are in the
information industry. Many of them service whole new markets that didn't exist just a few
years ago. There was no position called "Webmaster" in 1991 because the Web didn't exist.
But now, that particular job category is one of the fastest growing in the overseas. The global
economy I am talking about is being made possible by technology. And that's why it's so
important that you understand how to use Information Systems Technology instead of just
computer technology. There's a big difference between the two, and we'll talk about it more.
Transformation of Industrial Economies
"In a knowledge- and information-based economy, knowledge and information are

key ingredients in creating wealth." Think back to the early 1900s when the horse and buggy
were the main form of transportation. Along came a guy named Ford who built a whole new
industry around the automobile. Many jobs, such as horse groomers, horse shoers, and buggy
manufacturers, were lost forever. Now think about all the new jobs that were created - not
just in the factories but all the other businesses associated with the car. The people in the
horse and buggy industry adapted, retrained for the new jobs, and the whole country changed.
The same thing is happening now with the information industry. Many of the new
jobs that are being created have better working conditions, better pay, and more advantages
than the old jobs had. You just have to be equipped to take advantage of the situation. You
have to take advantage of retraining opportunities. You have to gain the skills necessary for
the transformation of the industries that have been a mainstay of this country. It's not that
hard - it just takes a lot of hard work.
We often think of industries such as manufacturing and financial institutions as

information-based. But even farmers and ranchers in this country are learning information-
based skills so that they can become more efficient and cut costs. They are taking advantage
of the technological explosion by using computers and Global Positioning Systems on their
farms and ranches to increase crop yields or reduce workloads. They're catching on to the
idea that Information Systems are a key to success.
Transformation of the Business Enterprise
You can't help but know about the entire job cuts occurring in our country. It seems
like every week we hear about thousands and thousands of people losing their jobs. Back in
the 80s most of the job losses were in the blue-collar sector. In the 90s it seems many of the
cuts are being made in the white collar, management jobs. Why? Think about it. Technology,
to a large extent, has driven organizations to change the way they operate and that includes
the way they manage. We're going to take an in-depth look at how organizations work and
how they've been transformed by technology.

But it isn't always bad! You just have to ask yourself this question: "With all the job
losses in the last few years, many driven by technological changes, why has the Indian
unemployment rate dropped to it's lowest in decades and remained so low?"
1.10 Contemporary Approaches to Information Systems
There are several different approaches to Information Systems: technical, behavioral,

socio-technical. Think of this analogy: A "techie" looks at most things associated with
computing as a series of zeroes or ones. After all, everything in a computer is ultimately
reduced to a zero or a one. So using the technical approach, you could say that 2 + 2 = 4. The
behavioral approach, on the other hand, takes into account the very nature of human beings.
Nothing is totally black and white. Therefore the behavioral approach to the same equation
would be "2 + 2 = maybe 4 or perhaps 3.5 to 5.5, but we'll have to put it before the committee
and see what the next quarter's figures say." Neither approach is better than the other,
depending on the situation. Neither approach is more right than the other, depending on the
situation.
An organization can't afford to view its information resources as belonging to either

the techies (technical approach) or the non-techies (behavioral approach). Responsibility for
information belongs to everyone in the organization. This is the sociotechnical approach, that
is, a combination of the two. Everyone has to work together to ensure that Information
Systems serve the entire organization.
To help you understand the importance of viewing Information Systems through the
sociotechnical approach, look at what the current trade journals are saying. David Haskin,
writing in the April 1999 issue of Windows Magazine, quotes Steve Roberts, vice president
of information technology for Mind Spring Enterprises, an Atlanta-based Internet service
provider: "The gap in understanding between technical and non technical people is the
biggest challenge I've seen." Haskin goes on to say, "Because technology is the bedrock on
which successful businesses are built, the stakes in making this relationship work are high.
Failing to use the correct technology can put you at a competitive disadvantage, and glitches
in existing technologies can bring a business to a grinding halt."
Information Systems and the use of technology belong to everyone in an organization.

This concept is best carried out through a sociotechnical approach, which allows both the
technical and behavioral approaches to be combined for the good of the organization.
1.10 Information System as a Strategic Resource
Information can be exploited as a strategic resource at three different levels:
• National
• Company
• Individual
National Level
Developed nations have adopted the diffusion of information systems and

technologies as a national policy. There appear to be two approaches at the national level.
Countries like Japan and the United Kingdom have invested in the technical infrastructure

first whereas France has determined educating people on how to use IS as a priority in order
to enable them to leverage the power of information and communication technologies.
Company Level
Many companies have attained higher product and service quality, shorter product
cycles, lower costs and better responsiveness to customer requirements through the use of IS.
Information systems allow the automation of certain functions (eg: inventory management or
sales order processing), provide critical information for decision making and integrate
business processes. Successful companies leverage the power of information as a competitive
weapon.
Individual Level
Managers and Information Systems
You will be exposed to information systems as a business professional in whichever

field you are working in, be it sales, manufacturing, accounting, finance, banking or
consultancy. This is inevitable.
You will not only be users of information systems but you will also be expected to
analyse the system to identify its strengths and weaknesses, recommend changes for
improvement and participate in their implementation.
But don't forget information systems are a means to an end, not an end in themselves.
Information systems are powerful valuable tools but not magic. If you automate a business
process that is a mess, you end up with an automated mess!
Managers must take IS in the context of business activities and purposes and use
information as a resource, like money, equipment or energy.
Managers must use IS to:
• access information
• interprete information
• incorporate information in decision making
Managers must exploit IS because of:
• rapid changes in technology

• intense international competition
• faster product life cycles
• more complex and specialised markets
Managers:
• are responsible for investments in IS

• need to be proactive and selective
• must understand how IS are used in the functional areas of business.

1.11 The New Role of Information Systems in Organizations
Managers can't ignore technology any more and pass it off to secretaries or clerical workers
or the Information Technology department. Information Systems are critical to the success of
an organization at all managerial levels.
The Widening Scope of Information Systems
If you take a look at the above figure you can understand the evolution of Information
Systems in organizations. Technology was considered, well, too technical for the rest of us to
understand. Computers were relegated to the back room with a few technicians running
around in white coats. No one else understood what these people did or how they did it. It
was a different world and actually seemed disconnected from the mainstream operations of
the company.
As the time line indicates, technology and its associated Information Systems are now
integrated throughout the organization. Everyone is concerned about technology’s role and
impact on their work activities. End users take on greater responsibilities for the success of
Information Systems and are actually doing a lot of the work that once belonged to the
techies. Even the executive levels of an organization can no longer ignore the technology and
pretend that it belongs to someone else.
We are constantly bombarded with new tools, new technology, and new methods of
doing business. It almost seems as though just as you master a word processing program, here
comes a whole new program you have to learn from scratch. But the plain fact is that
organizations, especially larger ones, just can't change as fast as the technology. Companies
make huge investments not just in hardware, but in software and persware. Training people,
building new operating procedures around technology, and changing work processes take far
longer than the technological pace will allow.
The introduction of new technology can severely disrupt organizations. Productivity

naturally slips. Learning curves cost time and money. Most system installations or changes
used to affect mainly data workers or production workers. Now they affect every level of the
organization, even the management and strategic levels. Every part of the organization is
involved in the introduction or change of technology and everyone plays a part in its success.

The Network Revolution and the Internet
Even though the Internet as a whole has existed since 1969, the World Wide Web
didn't exist until around 1993-1994. That's less than 10 years. Now you can't pick up a
magazine or a newspaper, turn on the television or radio, even drive by a billboard, without
some kind of reference to "dot com." Businesses are rushing to the Internet in an effort to
keep up with the competition or to create whole new businesses. Now organizations struggle
with such issues as how to design and develop a Web site or how to determine a fair email
policy for employees.
The fastest and biggest change in modern computing is the Internet. To say that the
Internet is transforming the way we live, work, and play is probably the greatest
understatement in years. Businesses can create new opportunities but they can also lose
opportunities just as quickly. Now an organization has to design new systems, or transform
old ones, with not just the company in mind, but 100 million other users of the Internet,
Extranets, and Intranets. They have to decide how much or how little information to provide
in what way, with what level of access, how best to present it, etc. It's a huge job!
New Options for Organizational Design: The Networked Enterprise
Many of the job losses of the 1990s occurred because technology allowed
organizations operate efficiently with flatter organizations - with fewer levels of bureaucracy.
One manager can now oversee a larger group of people. More important, technology
increases the span of communication a manager can accomplish with a single email. You can
make information available to a greater number of people much more easily than ever before.
But wait. You can make that information available to more people, but you have to
train them how to use it, and when it's appropriate to use it and with what latitude they can
use it. Again, it all comes back to the "persware" portion of the triangle. Yes, your hardware
enables more people to connect to the Information System, and the software is becoming
much easier to use and more widespread than ever before. But you still have to concentrate
on the people who are using the software to connect to the hardware.
Technology now allows workers to work from anywhere. It's becoming common for
companies to literally shift their work through time zones. That is, the person in New York
will shift blueprints for a new product to a worker in California. The Californian can then
collaborate on the product for an additional three hours before zipping it to another person
across the ocean who will work on it while the others sleep. Talk about telecommuting!
Technology now allows companies in foreign countries to merge their organizations

in ways never before possible. Think of Daimler from Germany and Chrysler in Michigan.
Opportunities for new products and new production methods exist with this merger.
However, think of the challenges it poses to management information systems and
employees.

The figure you see depicts the possibilities of virtual organizations. XYZ and ABC
companies can team up, work on a project, and then go their separate ways. ABC could then
seek out LMN corporation to develop a new technology from which both will gain but which
neither could accomplish on their own. This is happening more and more in technology
companies. In November 1998, America Online purchased Netscape. At the same time AOL
announced a collaboration with Sun Microsystems to develop and deliver enhanced
technology that AOL couldn't produce on its own. A few years ago, virtual organizations
were difficult to develop and even more difficult to manage. New technologies and new
management information systems now make such partnerships easier and more productive
than ever before.
As we'll see in future chapters, new technology allows businesses to reorganize their
workflows, allowing them to become more efficient and to meet new challenges. The
potential for saving money is tremendous, and so are the opportunities to better meet
customer demands.
A few years ago we couldn't imagine having Levi Strauss make a pair of jeans just for
us. It wasn't possible for a gardening company to produce a catalog strictly for our own
backyard. There was no way for an airline reservation company to know your favorite city to
visit and send you special ticket deals for a weekend getaway in a weekly email message. All
that is now possible thanks to the newer management information systems. But with all these
new opportunities come new challenges and problems.
Enterprise Resource Planning, which we'll talk about in other chapters, is only
possible through new and improved technology. Companies are realizing that they can't
afford "islands of information" and must have the means to share information resource across
all boundaries. And speaking of boundaries, most of those are either rearranged or eliminated

because of technological changes. Suppliers, customers, and governmental agencies are now
linked electronically to organizations that increase the efficiency and decrease the cost of
operations in what are called inter organizational systems.
One common mistake with many organizations wanting to do business on the Internet
is the idea that they can simply throw up a Web site, add an email software program for
customer communication, and they are ready to do business in cyberspace. They haven't
addressed any of their internal processes and possible changes to the way they do business.
They've spent hundreds of thousands or millions of dollars and can't get enough sales to
support a day's worth of expenses.
Electronic markets are allowing businesses to take advantage of technology to create

new methods of buying and selling. For a while it seemed as though the middleman was
going out of business because of the direct connection between customers and merchants.
While this is true in some industries, new opportunities are springing up for the middleman in
other areas. We'll look at this issue in more detail later.
Amazon.com, the largest retailer on the Internet selling books and CDs, loses millions
of dollars a year and yet is one of the best success stories in E-commerce. Its fiercest rival,
Barnes & Noble Books, has also spent millions of dollars converting traditional retailing
operations to the Internet. Unfortunately, Barnes & Noble's efforts at E-commerce are
considered somewhat of a failure. Why? Because Barnes and Noble hasn't fully changed its
core processes to accommodate the changes required for doing business on the Web.
There are many opportunities offered by the Internet, Extranets, and Intranets. Yet
there are many problems associated with developing a company's electronic commerce and
electronic business. It is easy to put up a Web site - a snazzy, colorful Web site that looks
very pretty and may even be easy to use. But you must consider how you're going to
incorporate that part of your business with the other, more established methods of doing
business. What internal processes must you change or adapt? What new processes must you
establish? What training must you do with the people who will run the E-business, both
technical and non-technical?
Employing new Information Systems in an organization requires changes to old

methods and processes. Managing the changes is as important to the success of the new
technology as managing the system itself.
1.12 Summary
Information Literacy is more than just clicking a mouse, pounding the computer
keyboard, or surfing the Web. It's about integrating various elements of an organization,
technical and non-technical, into a successful enterprise. As a successful manager you must
concentrate on all three parts of the Information Systems triangle (hardware, software, and
persware) and integrate them into a single, cohesive system that serves the needs of the
organization, the wants of the customer, and the desires of the employees. The more complex,
the harder to manage, but the greater the payoff.

Leaning Objectives
1. To understand the concepts of Systems and its components

4. To Explain the Specification of Information Systems
5. To know the System approach in Problem Solving
2.1 Introduction
When you begin the study of information systems, you should become acquainted
with a theoretical framework for understanding their use, development, and effect on
organizations; that is, you need to have an understanding of systems concepts as a foundation
for further study. A system is a collection of people, machines, and methods organized to ac-
complish a set of specific tasks. Information systems-which are a major topic in this text-have
the same components and characteristics as systems in general.
This lesson introduces the concepts of systems, their characteristics, and their
interaction with the environment. As a manager, you'll constantly be dealing with systems,
and you'll need feedback about their performance. Information is the feedback you need to
determine if systems are achieving their objectives, operating with the necessary components,
and meeting the necessary standards. Information systems are designed to give managers the
information they require as feedback.
In this lesson you will learn about the systems approach to problem solving also. As a
manager, you will be dealing with many types of systems, and you will be responsible for
improving their performance. For example, you'll determine if procedures, personnel, and
equipment need to be changed to achieve objectives. Or you'll need to assess the effect of
new equipment on current work methods, procedures, and organization. The systems
approach to problem solving will help you deal with these kinds of tasks.
2.2 Systems Concepts
Let us see the very simple meaning of any system. A system is a set of inter-
dependent components (some of which may be systems in their own right), which
collectively accomplish certain objectives.
In other terms we can say that a system is an integrated set of components, or entities,
that interact to achieve a particular function or goal. Systems have characteristics such as
boundaries, outputs and inputs, methods of converting inputs into outputs, and system
interfaces. Systems are composed of interrelated and interdependent subsystems.
Examples of systems are all around us-in fact; an excellent example is your class. The
components of the classroom situation, including an instructor, the students, textbooks, and
facilities, all interact to make the accomplishment of learning goals possible.
Example: A Classroom System
A business is also a system. A business uses resources such as people, capital, ma-
terials, and facilities to achieve the goal of making a profit. Business procedures, such as
order handling, marketing research, financial planning, and manufacturing, are the
interactions that need to be managed to achieve this objective.

Let us now see the components of a system which are common to all kinds of system
in detail.
2.2.1 System Boundaries
Every system has a boundary that defines its scope of activities. For example, the ac-
tivities in your class include lectures, discussion, continuous evaluation, grading, and
preparation of assigned course work. These activities may represent the boundary of the
system for which a teacher is responsible. Within the system of the classroom, the teacher is
responsible for organizing class time, assigning homework to students, and evaluating student
progress. The boundary, then, delineates an area of responsibility. When defining a system,
you must establish a boundary.
2.2.2 Systems and Sub Systems

Systems may consist of numerous subsystems, each of which has elements, interac-
tions, and objectives. Subsystems perform specialized tasks related to the overall objectives
of the total system. For example, an educational system may consist of individual courses that
are subsystems. Each course provides specific knowledge that is a part of the overall
educational system and contributes to its goals.
2.2.3 Outputs and Inputs

The inner workings of a system or subsystem are organized to produce outputs from
inputs. In this conversion process, some value or utility should be added to the inputs. For
example, a training program should produce trained employees with certain skills,
knowledge, or behavior from its inputs-untrained employees
The outputs of one subsystem usually become inputs into the next. The outputs of a
course in introductory data processing concepts, for instance, become inputs into the next
course in Java programming.
As you would expect, the outputs of a subsystem have to adhere to certain standards
to be acceptable to the next. If students coming out of the introductory data processing course
don't understand basic concepts of file organization and file processing, they won't have the
prerequisite skills needed for Java. If they were not permitted to enter Java until they meet
certain standards, though, the problem would be alleviated. The more exactly standards are
adhered to; the easier it will be to interface the two courses, or subsystems.
2.2.4 Subsystem Interface

An interface is a connection at system or subsystem boundaries. An interface serves
as a medium to convey the output from one system to the input of another system. An
example will help clarify this concept. Two typical business systems that interface with each
other are inventory control and purchasing. If inventory levels drop below a certain level,
then additional stock of these items should be purchased. Purchasing will need to know what
quantity of a particular item to obtain to replenish the stock and information on sales and
inventory turnover to learn which items are in greatest demand so these items can be
replenished on a timely basis. An inventory control system will provide information on stock
to be reordered based on sales and inventory turnover trends.
However, if the inventory control subsystem triggers erroneous information about the
amount of stock to be reordered, then inputs into purchasing will be wrong. This problem can
be partially overcome by establishing an economic order quantity, or the quantity of an item
that is most economical to buy, for each item in inventory. This quantity, derived from order
history and inventory turnover rate, can serve as a standard and prevent reordering too much
or too little stock.

2.2 5 Interface Problems

In the previous section we mentioned that adhering to standards can alleviate some
interface problems. However, you might encounter other types of interface problems.
Sometimes the output of one subsystem is not sufficient to accommodate the needs of the
next subsystem. For example, the production subsystem may not be able to produce enough
stock to meet sales demands during certain peak periods. One way of handling this interface
problem is through the use of slack resources. In this situation a business can build excess
inventory during slack times to meet the demand for inventory at peak times.
Another system interface problem can occur between the authoring subsystem and the
editorial subsystem in the development of a textbook. Authors who wait until the last minute
to finish their writing may not be able to produce a manuscript fast enough to meet
production schedules, which involve editing, artwork, layout and design, typesetting, and
proofreading tasks. The publisher can avoid this problem in several ways. First, the publisher
can ask the author to complete several chapters before production activities begin. This
procedure is another example of using slack resources.
Second, the publisher can ask the author to adhere to certain standards for input into
the production subsystem. For example, the author can create and store all text using a word
processing package that can be transported to a computer-based typesetting system without
reeking.
Third, the author could hire a library researcher, photo researcher, and typist to
provide a support subsystem to expedite the development of manuscript. This method creates
a new subsystem to solve a system interface problem.
2.2.6 System and its Environment

The system's environment consists of people, organizations, and other systems that
supply data to or that receive data from the system. Not surprisingly, different managers
perceive the environment differently. A sales manager, for example, may envision the system
environment to be the company's customers and vendors of the products and services being
marketed. On the other hand, the owner of the business may perceive the environment to
include the firm's competitors, financial institutions that provide resources for expansion, and
government agencies with jurisdiction over company plans and products. Moreover, various
kinds of systems may interact with the environment in different ways.
2.2.7 System Feedback

A system needs feedback to do its job. Feedback is an indicator of current perfor-
mance rates when compared to a set of standards. With effective feedback, continuing
adjustments in the activities of a system can be made to assure that the system achieves its
goals. Measuring performance against a standard is an effective control mechanism.
Employees need feedback to learn how well they are achieving job goals. Students receive
grades or other kinds of evaluations from instructors that show whether the students are
meeting course objectives.
The good thing about feedback is that it usually increases effort. For example, tennis
players often perform better when they are keeping score. When salespeople receive positive
feedback, it increases their motivation to achieve a sales quota. Negative feedback may also
serve a useful purpose. Negative feedback is designed to correct or guide activities that are
not consistent with achieving the goals of the system. If salespeople are not achieving quotas,
they may want to rethink current sales techniques or reorganize their time. Similarly, if
students receive low grades, they may need to improve study habits, obtain tutoring, or enroll
in courses that better match their abilities or backgrounds.

2.2.8 System Entropy

Systems can run down if they are not maintained. Systems entropy corresponds
roughly to chaos or disorder - a state that occurs without maintenance. If employees do not
have opportunities to learn new concepts and techniques, the skills they apply to performing
job tasks will become out of date. The process of maintaining a system is a process of
decreasing entropy or increasing orderliness. Sending automobile mechanics to training
classes to learn new diagnostic techniques is an example of decreasing entropy. Orderliness
can be achieved through preventive maintenance checks, such as a yearly physical
examination for an employee or a routine tune-up for an automobile, and then taking action
as a result of these regular checks. These checks provide valuable feedback to help detect
faults or problems when none have been anticipated. Diagnostic tools for equipment and
machinery help prevent downtime, which may cause delays in production and cost thousands
of dollars in lost business.
2.2.9 System Stress and Change

Systems change over time. Some of these changes occur because of identified prob-
lems, new business opportunities, and new management directives. Systems may also change
as a result of stresses. The achievement levels needed to meet existing goals may change. For
example, because of reduced profit margins on sales, a division sales manager may insist on a
sales increase of 10 percent instead of 7 percent to achieve the same profits. The tendency is
to localize the stress so that only one subsystem, in this case the division sales force, feels
most of the pressure for adjusting to new demands.
It is easier to deal with change within one subsystem than within the total system
because stress may require rethinking existing work methods and organization. In this case
the sales manager may have to develop more effective procedures to improve the profitability
of sales. The sales manager may recommend cutting down calls to smaller customer accounts
and substituting telemarketing to service their needs. Salespeople might need to reallocate
their time so they can pay special attention to customers who purchase the most profitable
product lines and encourage customers who purchase less profitable lines to look at high-
margin products. All these procedures require a close analysis of the current system, changes
in work procedures, and effective time management.
2.3 Systems concepts in Business
Now that you have a general picture of how a system works, it will be helpful to look
more closely at business systems. The systems approach is a way of analyzing business
problems. This approach views the business organization as a system of interrelated parts
designed to accomplish goals. Each subsystem is both a self-contained unit and a part of a
larger system. Managers must understand the goals of the total system and design the
function and subsystems within the total system to accomplish the goals.
More specifically, management is the practice of organizing resources including
people, materials, procedures and machines to achieve objectives. In other words, it entails
organizing subsystems to accomplish specific tasks. Using a system approach, a manager
organizes various activities of the business into separate organizational subsystems.
To consider an example, the market research subsystem of the business may obtain
information from the customers about modifications that about to be made in the firm’s
products and services. The market research subsystem can transmit this information to the
manufacturing subsystem that builds product design changes into its processes. Finally, the
marketing subsystem sells the finished products to the customers. If technical problems
occur, the service subsystem may need to provide follow-up support. The interactions among

these functional subsystems are depicted in the following figure.

Input Process Output
Manufacturing Subsystem Customer needs
Marketing Subsystem Finished Goods
Service Subsystem Product in Use
2.4 Information System as a Sub System

An information system consists of components that interact to achieve the objective of
providing information about day-to-day activities that managers can use to control business
operations. Information systems can also provide information to enable managers to allocate
resources and establish long-range business plans. An information system contains such
elements as hardware, software, personnel, databases, and procedures to accomplish its
objectives. The hardware consists of the computer and computer-related activities. Software
consists of the instructions that the hardware uses to process information. Software includes
both application software and system software. Application software consists of the programs
written to support specific business functions, such as order entry, inventory control, and
accounts receivable. System software enables the hardware to run application software.
System software consists of the programs that handle such functions as sorting data,
converting programs into the machine language the computer can understand, and retrieving
data from storage areas.
A general model of an information system is shown below.
Hardware Softwar
DATA People
INFORMATION
DataBase Procedure

Subsystems
Operational systems, which are designed to provide information about day-to-day

activities, are composed of subsystems that accomplish specialized tasks. A mail-order
business, for example, needs a system to process customer orders. The order-processing
system actually consists of subsystems set up to handle incoming orders, update inventory
levels, and bill customers. Other subsystems are created to purchase new stock, to handle
accounts payable transactions, and to apply cash receipts from customers to outstanding
accounts receivable balances. Each subsystem performs a specialized task that supports the
business objectives of increasing sales and providing customer service. You can see how
these subsystems are organized in the following figure.
If one of these subsystems breaks down, the overall business will feel the effect. For
example, if the mail-order company does not maintain sufficient inventories, customers may
become frustrated with constant back orders and shift their business to other companies.

Outputs and Inputs

An information system, like any other system, receives inputs of data and instructions,
processes the data according to these instructions, and produces outputs. This information-
processing model can be used to depict any information system. An inventory update system
is shown below.
Sales Sales
Transaction Listing
Inventory Update Reorder

Report
Old New
Inventory Inventory
Master Master
In an inventory update procedure, the inputs are sales order transactions and an old
inventory master file. During the update procedure, the item quantities for each item on a
sales order transaction are subtracted from the existing inventory level for that item in stock.
The new inventory level is then written to the new inventory master file. The outputs of this
system are an updated inventory master file, a reorder report, and a sales listing. A reorder
report lists any items in inventory that have fallen below their desired inventory level and
provides a purchasing manager with feedback about items that need to be reordered.
System Feed Back
An information system provides system feedback to a manager about day-to-day
activities and about deviations from planned activity. The manager can use this information
to supervise daily operations, such as credit checking and billing, and to reorganize resources
to achieve objectives more effectively. In the inventory control example, one of the outputs
was a reorder report indicating which inventory items need to be reordered. A purchasing
manager could use this report to reorder additional stock on a day-to-day basis.
Middle managers might want feedback about which items in inventory are moving
rapidly and which items are moving slowly so they can reallocate the investment in inventory
to minimize waste and maximize profitability. The information systems providing feedback
that can be used to allocate resources effectively, such as inventory and personnel, are called
tactical systems.
Subsystem Interface
As with other systems, interfaces exist between the subsystems of an information sys-
tem. Again, the outputs of one subsystem become the inputs into the next. For example, the
outputs of a sales order entry system become the inputs into an invoicing system. If the
outputs of one system are not correct, however, the next subsystem will be affected. If the
price of an item is entered incorrectly during order entry, then the charges to the customer
may be incorrectly calculated during billing.
Internal Controls
Good information systems also have internal standards to make sure that data are
processed accurately. Input controls, for example, ensure that input data are valid before they
are processed. Another type of control is a password security procedure designed to protect
against unauthorized access and update of data. All in all, standards make sure the system
works properly. Without controls, the data printed out on reports may be inaccurate, and
managers may not be able to trust the information system to provide valid results. If
unauthorized users update data files or if input data are not valid, managers may not even
know that the output generated in reports is invalid, and thus they may make decisions using
erroneous information.
2.5 The Structure of an Enterprise

As we know, the entire enterprise has been organized into subsystems, including the
marketing subsystem, the service subsystem, and the administrative subsystem. The
marketing subsystem promotes and markets microcomputer products and services. When cus-
tomers have problems with their microcomputers or need preventive maintenance, they use
the service subsystem. Finally, the administrative subsystem takes care of billing customers,
purchasing equipment and supplies from vendors, paying vendors, and handling accounting
activities. The organizational structure of the dealership is depicted in the following figure.
Owner

Marketing Service Administratio
n
The marketing subsystem of the dealership is managed by a sales manager who

recruits salespeople, including experienced veterans and new trainees, to demonstrate and sell
the equipment. These salespeople are trained to follow certain procedures, such as giving
equipment demonstrations and making follow-up calls. These procedures are an important
part of the "system" of selling microcomputer hardware and software. When they are not
followed, profitability suffers.
The sales manager needs an information system to provide feedback on how the
system is working. On a day-to-day basis, he may receive information about salespeople who
have successfully closed sales, about customers who are complaining, and about technical
problems with equipment. This feedback makes it possible to review the procedures and
activities of the current system. For example, if a particular
A Contextual view
Any system operates by interacting with its environment. The contextual view
describes graphically the interaction of the system with the various entities in its
environment. The interactions consist of dataflows from and to such entities.The contextual
view clarifies the boundary of the system and its interfaces with the environment in which it
operates.
Contextual View
A Control view
Any system must manipulate certain variables in order to achieve its objectives. It
determines the manipulation needed by processing its outputs/states in relation to certain
control parameters.

Control View
Frequently, complexity takes the form of a hierarchy, whereby a complex system is
composed of interrelated sub systems that have in turn their own subsystems, and so on, until
some lowest level of elementary components is reached. The choice of what components in a
system are primitive is relatively arbitrary and is largely up to the discretion of the observer
of the system. Intra-component linkages are generally stronger than inter-component linkages
(components of a system are loosely coupled, but components themselves are cohesive).
Hierarchical systems are usually composed of only a few different kinds of subsystems in
various combinations and arrangements (same components can be reused). A complex system
designed from scratch never works and can not be patched up to make it work. You have to
start over, beginning with a system that works.
2.6 Some basic concepts & strategies in the study of systems

• Abstraction: We have developed an exceptionally powerful technique for dealing
with complexity. We abstract from it. Unable to master the entirety of a complex
object, we choose to ignore the inessential details, dealing instead with the
generalized, idealized model of the object.
• Formality: Rigor at each stage in the development of a system.
• Divide and conquer: Divide a complex problem into a set of simpler problems that
can be solved.
• Hierarchical ordering: Order the simplification of the problem in ``divide &
conquer" in hierarchies.
• Cohesion & coupling: Modularise the system such that interactions within
components (cohesion) is maximised and interactions between components (coupling)
is minimised. This way, the impact of errors, when they arise, is localised and does
not cascade through the system. Diagnosis of offending components is also made
easier.
• Information hiding: Each module (or subsystem) must have available to it just the
information that is needed by it.
• Conceptual integrity: Consistency in design.
• Completeness: Ensuring that the design meets all the specifications.
• Logical independence: Emphasis on the statement of system objectives in terms of
logical functions independent of physical implementation.

• Correctness & Efficiency: Correct in the sense that the design meets all the user
requirements. Efficient is that the system accomplishes the objectives with minimum
computing resources.
2.7 Types of Information Systems
Information systems can be classified in many ways, but for our purposes here, we
will consider their classifications based on the mode of processing, on the system objectives,
and on the nature of interaction of the system with its environment.
2.7.1 Classification by mode of processing

• Batch processing systems: The transactions are collected as they occur, but
processed periodically, say, once a day or week.
• On-line batch systems: The transaction information is captured by on-line data-entry
devices and logged on the system, but it is processed periodically as in batch
processing systems.
• On-line Real-time systems: The transaction data capture as well as their processing
in order to update records (and generate reports) is carried out in real-time as the
transaction is taking place.
2.7.2 Classification by System Objectives

• Transaction Processing Systems: Their objective is to process transactions in order
to update records and generate reports, i.e., to perform score-keeping functions.
• Decision Support Systems: Their objective is to support the managerial decisions.
Usually, these systems are based on a model of the decision-making domain, and
utilize techniques from management science, finance or other functional areas of
business in order to build such models. These systems are also used often for
attention-directing purposes, i.e., for directing the attention of managers to a
problematic aspect of operations.
• Expert Systems: These systems incorporate expertise in order to aid managers in
diagnosing problems or in problem solving.
2.7.3 Classification based on the nature of interaction with environment

• Transformational Systems: These are systems that transform inputs received from
the environment in order to generate reports (output).
• Reactive Systems: These are systems characterized by being, to a large extent, event-
driven, continuously having to react to external and internal stimuli.
The components of accounting systems such as payroll, general ledger are, it should
be obvious, usually batch processing systems, and also transaction processing systems that
are transformational systems. Systems for determination of sample sizes for audit testing, on
the other hand may be decision support systems. Systems aiding provision for doubtful
accounts (or loan loss reserves for financial institutions) may be expert systems.
2.8 Specification of Information Systems
Specification of any system before its development is crucial. Specifications perform

for information systems the same function that blue-prints and engineering specifications
perform for physical structures. Specifications serve as benchmarks for evaluating designs as
well as their implementation. They also facilitate quality assurance via verification (are we

building the system right, ie., do the design and implementation meet the specifications?) and
validation ( are we building the right system, ie., does the system meet the user needs?).
2.8.1 Formal vs. Informal Specifications

In the development of information systems in business, informal specifications
through graphical modeling have been used at least since late 70s. We shall be studying many
of these modeling tools. Recently, formal specification languages (such as Larch, VDM, Z,
FOOPS and OBJ) have been developed. While their use in business systems development is
in its very early stages, they are expected to play an important role in the future. These formal
specification techniques attempt to mathematically specify structure, function, and behavior
of information systems.
2.8.2 Components of specifications

Specification of an information system is given by their:
• Structure: How it is organised.
• Function: What it does.
• Behavior: How it responds to events and stimuli.
• Data: Its meaning and organization.
Most tools co-ordinate information systems projects through a project or system
dictionary. The function of the dictionary is to standardise the use of terms throughout the
organisation and to serve as a repository of all common information in the project. It enforces
consistency as well as (relative) completeness of the specifications, and facilitates verification
& validation of such specifications. It also serves as a means of communication between the
different persons on the information systems building team. The figure below shows the
various components of the specifications and the modeling techniques utilised. We will be
studying some of those techniques in this course.
2.9 Using the Systems Approach in Problem Solving
An owner of a business like the microcomputer dealership must constantly analyze

problems and reorganize the resources of the system to deal with these problems effectively.
The systems approach is a valuable method of problem solving that takes into account the

goals, environment, and internal workings of the system. The systems approach to problem
solving involves the following steps:
Define the problem.

Gather data describing the problem.
Identify alternative solutions.
Evaluate these alternatives.
Select and implement the best alternative.
Follow up to determine whether the solution is working.
We can understand how the systems approach works by applying it to a problem that
the microcomputer dealer might experience.
Define the Problem

The first step in the systems approach to problem solving is to define the problem.
Defining the problem is one of the most important parts of the system study, because if the
wrong problem is identified, the entire effort to change the system will be off track. At the
outset, some of the problems that are identified may be symptoms of the real problem. In
order to distinguish between symptoms and problems, it is necessary to gather data describing
the problem. Let's say that in this case the owner is concerned about the fact that many of the
salespeople are not meeting their quotas. She decides to start a systems study by collecting
more information about the problem.
Gather data describing the problem

The owner may study the environment, current standards, management, input re-
sources, and internal procedures to gain an understanding of the problem. The first place the
owner might look is the environment. The environment of the microcomputer dealer includes
its vendors, its customers, its competitors, and the local community. From this investigation,
the owner might learn that local competitors are selling comparable microcomputers at prices
10 percent to 15 percent less the firm can offer.
Next, the owner might look at the dealership's standards to determine if they are valid
in the face of the competitive environment. It might turn out that a goal of increasing gross
sales by 10 percent for the year is unrealistic when the competition is cutting prices. Another
area the owner can analyze is management. The owner needs to learn if the sales manager is
doing a good job. If the sales manager is not providing salespeople with effective training and
feedback regarding their performance, they may feel frustrated.
Input resources are another area that should be analyzed. The owner needs to find out
if new sales and technical representatives are being recruited and if these employees are
trained to demonstrate computer equipment and software. If new recruits lack knowledge of
the technical features of the equipment, for example, they will fail to win new business. If
sales materials are not kept up-to-date, customers may not learn about new product features.
Work methods and procedures also need to be studied. If salespeople are not trained to follow
up on new prospects, the company could lose valuable business. If technical support
personnel cannot diagnose and solve service problems on a timely basis, customers may
hesitate to purchase more equipment.
One of the major problems identified in this case is that competitors are charging
lower prices for comparable products. Many of the difficulties the dealer has identified are
symptoms of this fundamental problem. To address it, the owner has to identify and evaluate
some alternatives.

Identify Alternative Solutions

Given the fact that competitors have dropped their prices on comparable microcom-
puters, the owner needs to identify some alternatives responses. These alternatives might
include the following:
Alternative 1: Investigate alternative manufacturers of microcomputers to obtain
products at a lower cost per unit.
Alternative 2: Decrease the cost of sales by introducing mail-order sales supported by
telemarketing. Use salespersons for large accounts only. Cutting the cost of sales efforts
would make it possible to reduce machine prices to a more competitive level
Alternative 3: Differentiate the dealership's products by offering on-line diagnostic
support services for machine failure, service response time within 5 hours on a 24-hour basis,
and annual service checks.
Each alternative supports a slightly different strategy. Finding lower-cost manu-
factured goods represents a cost-cutting strategy. The second alternative, using mail order
sales and telemarketing, also supports a low-cost strategy because the cost of mail-order sales
would be less than the cost of a large sales staff. Finally, introducing on-line diagnostic
support services provides a "value added" feature. Upgraded technical support would justify
slightly higher equipment costs.
Evaluate the Alternatives

The owner evaluates the extent to which each alternative enables the organization to
achieve its objectives. As we saw, the owner's objective was to increase the overall
performance of sales personnel. Purchasing lower-cost products from suppliers would enable
the owner to cut prices, as suggested in the first alternative, but would create difficulty at the
service end if these microcomputer products were less reliable. This strategy might make it
more difficult for salespeople to meet their objectives. Introducing a mail-order program
would cut the cost of sales overhead. How ever, the mail-order program would require
creating a database of customer prospects and developing specialized promotional materials.
This strategy might free sales representatives to concentrate on direct sales to high-potential
accounts while using a less costly strategy to maintain the business of smaller accounts.
The final alternative would offer customers additional levels of service and technical
support that add value to the firm's products. Because service is one of the key criteria for
microcomputer selection, this strategy might work. However, it is costly and might not satisfy
the needs of economy-conscious small businesses that represent a large potential market
share.
Select and Implement the Best Alternatives

Let's say that the owner decides to develop and implement a mail-order program to re-
duce the cost of sales overhead to smaller accounts and to enable sales personnel to focus on
high potential accounts. This new strategy would require the owner to recruit new customer
service representatives or train current employees for telemarketing. The owner would also
have to develop and establish customer prospect databases, as well as a system for shipping
merchandise, billing, and authorizing credit transactions.
Follow up to determine whether the solution is working

The last step in the systems approach to problem solving is follow-up. In the case of
the mail-order sales alternative, the owner needs to determine if the system is meeting its
goals. If not, she has to make changes in management, standards, resources, and procedures
to achieve the objectives. If either one of the other two alternatives is selected, the owner also

needs to follow up to determine if the approach is improving sales. As you can see from this
example, the systems approach to problem solving is an important technique for the manager.
Every manager needs feedback to determine if the goals of the system are being achieved.
One of the most difficult tasks in a systems study is identifying information that managers
can use to determine how the system is working. This problem is as true in an organization
with a simple structure as it is in a more complex organization. The next section discusses the
characteristics of organizations with various structures.
2.10 Summary
This lesson introduces systems concepts hat provide a foundation for understanding
information systems in general and management information systems in particular. Managers
have to understand systems, their objectives, their components, and their activities.
Information about how a system is working provides tem with the feedback they need to
allocate resources to achieve their business objectives. Depending on the objectives of a
system, its components, standards, and interactions may differ. We have seen that an
information system provides feedback about the activities of the business. Information
Systems have the same characteristics as the other systems, including inputs and outputs,
processes hat transform inputs into outputs and methods of system control. In designing an
information system, the outputs must be defined to provide feedback for the business system.
Managers use this feedback to reorganize, simplify, and improve activities in the business
system so that the system can achieve goals more effectively. In the information-based
organization, managers must define their information needs and use information as feedback.

Learning Objectives
1. To know how information systems are built

2. To understand the problems encountered when you develop information systems
3. To learn the strengths and weaknesses of development methodologies.
3.1 Introduction
In the last lesson we have seen thoroughly about the concept of System and its components. Let
us have some insight now into the Development and Implementation of such systems as one of the major
responsibilities of any Manager is to develop the system through which he can exercise the functions of
management.
We know that information is an organizational resource which must be managed as carefully as
other resources. Costs are associated with information processing. It must be managed to take full
advantage of its potential.
The following paragraphs will give you some fundamentals you need to keep in mind while
developing information Systems.
• A system is a combination of resources working together to transform inputs into usable outputs.
• An information system is an arrangement of people, data, processes, interfaces, networks, and
technology that interact to support and improve both day-to-day operations (data processing,
transaction processing), as well as support the problem-solving and decision-making needs of
management (information services, management information systems, executive support).
• A computer application is a computer-based solution to one or more business problems or
needs. One or more computer applications are typically contained within an information system.
I could say that development of systems will begin with identifying the problems and ending with
the implementation and its maintenance.
• Systems Analysis and Design is a systematic approach to identifying problems,
opportunities, and objectives; analyzing the information flows in organizations; and designing
computerized information systems to solve a problem. Systems Analysts act as outside
consultants to businesses, as supporting experts within a business, and as change agents.
Analysts are problem solvers, and require good communication skills.
• A problem is an undesirable situation that prevents the organization from fully achieving its
purpose, goals, and objectives. An opportunity is the chance to improve the organization
even in the absence of specific problems. (Some might argue that any unexploited
opportunity is, in reality, a problem.) A directive is a new requirement imposed by
management, government, or some external influence. (Some might argue that a directive
until it is fully complied with is, in reality, a problem.)
3.2 System Development Life Cycle
There is a fundamental dilemma faced by anyone developing a computer application. Most

problems are so large they have to be split into smaller pieces. The difficulty lies in combining the pieces
back into a complete solution. Often each piece is assigned to a different team, and sometimes it takes
months to complete each section. Without a solid plan and control, the entire system might collapse.
Thousands of system development projects have failed or been canceled because of these complications.
Partly because of the problems that have been encountered in the past, and partly because of
technological improvements, several techniques are available to develop computer systems. The most

formal approach is known as the systems development life cycle (SDLC). Large organizations that
develop several systems use this method to coordinate the teams, evaluate progress, and ensure quality
development. Most organizations have created their own versions of SDLC. Any major company that
uses SDLC also has a manual that is several inches thick (or comparable online documentation) that lays
out the rules that MIS designers have to follow. Although these details vary from firm to firm, all of the
methods have a common foundation. The goal is to build a system by analyzing the business processes
and breaking the problem into smaller, more manageable pieces.
Improvements in technology improve the development process. The powerful features of
commercial software make it easier to build new applications. Programmers and designers can work with
larger, more powerful objects. For example, instead of programming each line in Java, a report can be
created in a few minutes using a database management system or a spreadsheet. Prototyping is a design
technique that takes advantage of these new tools. The main objective of proto typing is to create a
working version of the system as quickly as possible, even if some components are not included in the
early versions. The third method of creating systems, end-user development relies on users to create
their own systems. This method typically uses advanced software (such as spreadsheets and database
management systems) and requires users who have some computer skills.
It is important to be careful when you implement any new system. Case studies show that major
problems have arisen during implementation of systems. In fact, some organizations have experienced so
many problems that they will deliberately stick with older, less useful systems just to avoid the problems
that occur during implementation. Although changes can cause problems, there are ways to deal with
them during implementation.
There have been some spectacular failures in the development of computer systems. Projects
always seem to be over budget and late. Worse, systems are sometimes developed
A systems analyst facilitates the development of information systems and computer applications.
The systems analyst performs systems analysis and design. Systems analysis is the study of a business
problem or need in order to recommend improvements and specify the requirements for the solution.
System design is the specification or construction of a technical, computer-based solution as specified by
the requirements identified in a systems analysis.
Personal qualities helpful to systems analysts include:
• Problem-solving abilities
• Communication skills
• Computer/IT experience
• Self-discipline and Self-motivation
• Project management capabilities
Systems are enhanced for a number of reasons:
• adding features to the system
• business and government requirements change over time
• technology, hardware and software are rapidly changing
3.3 System Life Cycle – Stages and Activities

Before proceeding further, let us have a quick look at the stages every system is going through in
its lifetime in any organization.

If we are analyzing these stages we might come across the following activities done in
developing, implementing and maintaining a system. These activities are sequential in happening during
the process of developing any type of systems.
1. Identify problems, opportunities, and objectives
2. Determine Information Requirements
3. Analyze System Needs
4. Design the Recommended System
5. Develop and Document the Software
6. Implement and Evaluate the System
7. Maintain the System
Once we know the activities involved in the Development of Systems, it becomes necessary to
know how these activities are carried out by the companies. There are various methods or options a
company can have for developing and implementing its information systems. Let us see some of the
practices mainly followed by many of the successful companies.
3.4 Build IS vs. Buy IS
Although most of the companies capable enough to develop their own systems, an increasingly
popular alternative is to acquire systems developed by an outside vendor.
The advantage of developing your own system in-house is that it can be customized to the exact
requirements of your own organization. When you purchase it from an outside party it may be a bit more
generic and the organization may have to adapt its ways to the limitations of the software and other tools
used.
However, by purchasing systems off the shelf or from a vendor the organization avoids the costs
of in-house development. To some extent the development costs are spread out among all of the vendor's
customers. Also, the organization may have the benefit of buying systems that already has a proven track
record in similar organizations.
Even so, selection of new system for an organization is never a trivial matter. Alternative
solutions must be evaluated carefully, studying costs and benefits and making a determination of

feasibility. The same knowledge and experience that an analyst would use to design a new system must be
used to select a system that most closely meets the needs and objectives of the organization. And,
regardless of whether the software is written in-house or purchased from the outside, the transition to a
new system is always a serious challenge for any organization.
A more recent variation is the idea of neither building nor buying, but rather "renting" solutions
from an Application Service Provider (ASP). Unlike traditional software licensing in which an
organization takes possession of a copy of the software and runs it on its own computer, the
distinguishing characteristic of renting this from an ASP is that the system remains at the vendor's site,
runs on the vendor's hardware, and is used over a wide-area network or the Internet. An Application
Service Provider, then, is an independent third-party provider of software-based services which are
delivered to customers across a network. An ASP is a supplier who makes applications available on a
subscription basis. An ASP rents the use of an application, providing all aspects of deployment and
maintenance.
While this kind of arrangement frees the organization from having to be concerned about the
expense (in money, time, and human resources) of software upgrades and maintenance, a major concern
becomes network bandwidth. Since the application is run across the network, instead of on a local
machine, any network congestion or slowdown will directly affect response time for the end user.
Another concern is data security. Businesses are sensitive to the matter of personal customer data
and proprietary information traveling over network lines. And, depending on the nature of the application,
unless it is possible to isolate or partition the executable from the data, an organization's data may end up
being stored on off-site computers. If so, is the data secure and protected against loss or improper access?
Now you are having a clear idea about the ways we can develop our information systems and the
areas to consider in making a decision about it. Let us now proceed with the System Development
Activities in Detail.
3.5 Typical Tasks in the Development Process Life Cycle
Professional system developers and the customers they serve share a common goal of building
information systems that effectively support business process objectives. In order to ensure that cost-
effective, quality systems are developed which address an organization’s business needs, developers
employ some kind of system development Model to direct the project’s life cycle. Typical activities
performed include the following:
• System conceptualization
• System requirements and benefits analysis
• Project adoption and project scoping
• System design
• Specification of software requirements
• Architectural design
• Detailed design
• Unit development
• Software integration & testing
• System integration & testing
• Installation at site
• Site testing and acceptance
• Training and documentation
• Implementation
• Maintenance

After seeing all the above activities, it is time to know about the methodology or approach which
can be used in System Development. All these methodologies are using some of the above tasks through
which they all achieve 100 % in System Development.
3.6 Approaches in System Development
3.6.1 Ad-hoc Development

Early systems development often took place in a rather chaotic and haphazard manner, relying
entirely on the skills and experience of the individual staff members performing the work. Today, many
organizations still practice Ad-hoc Development either entirely or for a certain subset of their
development (e.g. small projects).
I can point out that with Ad-hoc Process Models, “process capability is unpredictable because the
software process is constantly changed or modified as the work progresses. Schedules, budgets,
functionality, and product quality are generally (inconsistent). Performance depends on the capabilities of
individuals and varies with their innate skills, knowledge, and motivations. There are few stable software
processes in evidence, and performance can be predicted only by individual rather than organizational
capability.”
Even in undisciplined organizations, however, some individual software projects produce

excellent results. When such projects succeed, it is generally through the heroic efforts of a dedicated
team, rather than through repeating the proven methods of an organization with a mature software
process. In the absence of an organization-wide software process, repeating results depends entirely on
having the same individuals available for the next project. Success rests solely on the availability of
specific individuals provides no basis for long-term productivity and quality improvement throughout an
organization.
3.6.2 The Waterfall Model

The Waterfall Model is the earliest method of structured system development. Although it has
come under attack in recent years for being too rigid and unrealistic when it comes to quickly meeting
customer’s needs, the Waterfall Model is still widely used. It is attributed with providing the theoretical
basis for other Process Models, because it most closely resembles a “generic” model for software
development.
The Waterfall Model consists of the following steps:
• System Conceptualization. System Conceptualization refers to the consideration of all aspects of
the targeted business function or process, with the goals of determining how each of those aspects
relates with one another, and which aspects will be incorporated into the system.
• Systems Analysis. This step refers to the gathering of system requirements, with the goal of
determining how these requirements will be accommodated in the system. Extensive
communication between the customer and the developer is essential.
• System Design. Once the requirements have been collected and analyzed, it is necessary to
identify in detail how the system will be constructed to perform necessary tasks. More
specifically, the System Design phase is focused on the data requirements (what information will
be processed in the system?), the software construction (how will the application be
constructed?), and the interface construction (what will the system look like? What standards will
be followed?).
• Coding. Also known as programming, this step involves the creation of the system software.
Requirements and systems specifications from the System Design step are translated into machine
readable computer code.

• Testing. As the software is created and added to the developing system, testing is performed to
ensure that it is working correctly and efficiently. Testing is generally focused on two areas:
internal efficiency and external effectiveness. The goal of external effectiveness testing is to
verify that the software is functioning according to system design, and that it is performing all
necessary functions or sub-functions. The goal of internal testing is to make sure that the
computer code is efficient, standardized, and well documented. Testing can be a labor-intensive
process, due to its iterative nature.
Problems associated with the Waterfall Model
Although the Waterfall Model has been used extensively over the years in the production of many
quality systems, it is not without its problems. In recent years it has come under attack, due to its rigid
design and inflexible procedure. Let me tell you the problems associated with the waterfall model below:
• Real projects rarely follow the sequential flow that the model proposes.
• At the beginning of most projects there is often a great deal of uncertainty about requirements and
goals, and it is therefore difficult for customers to identify these criteria on a detailed level. The
model does not accommodate this natural uncertainty very well.
• Developing a system using the Waterfall Model can be a long, painstaking process that does not
yield a working version of the system until late in the process.
3.6.3 Iterative Development

The problems with the Waterfall Model created a demand for a new method of developing
systems which could provide faster results, require less up-front information, and offer greater flexibility.
With Iterative Development, the project is divided into small parts. This allows the development team to
demonstrate results earlier on in the process and obtain valuable feedback from system users. Often, each
iteration is actually a mini-Waterfall process with the feedback from one phase providing vital
information for the design of the next phase. In a variation of this model, the software products which are
produced at the end of each step (or series of steps) can go into production immediately as incremental
releases.
Problems associated with the Iterative Model
While the Iterative Model addresses many of the problems associated with the Waterfall Model, it
does present new challenges. Let us see them as follows:
• The user community needs to be actively involved throughout the project. While this involvement
is a positive for the project, it is demanding on the time of the staff and can add project delay.
• Communication and coordination skills take center stage in project development. Informal
requests for improvement after each phase may lead to confusion -- a controlled mechanism for
handling substantive requests needs to be developed.
• The Iterative Model can lead to “scope creep,” since user feedback following each phase may
lead to increased customer demands. As users see the system develop, they may realize the
potential of other system capabilities which would enhance their work.
Variations on Iterative Development
A number of Process Models have evolved from the Iterative approach. All of these methods
produce some demonstrable software product early on in the process in order to obtain valuable feedback
from system users or other members of the project team. We will see them below.
3.6.4 Prototyping
The Prototyping Model was developed on the assumption that it is often difficult to know all of
your requirements at the beginning of a project. Typically, users know many of the objectives that they
wish to address with a system, but they do not know all the nuances of the data, nor do they know the
details of the system features and capabilities. The Prototyping Model allows for these conditions, and
offers a development approach that yields results without first requiring all information up-front.

When using the Prototyping Model, the developer builds a simplified version of the proposed
system and presents it to the customer for consideration as part of the development process. The customer
in turn provides feedback to the developer, who goes back to refine the system requirements to
incorporate the additional information. Often, the prototype code is thrown away and entirely new
programs are developed once requirements are identified.
There are a few different approaches that may be followed when using the Prototyping Model:
creation of the major user interfaces without any substantive coding in the background in order to give the
users a “feel” for what the system will look like, development of an abbreviated version of the system that
performs a limited subset of functions; development of a paper system (depicting proposed screens,
reports, relationships etc.), or use of an existing system or system components to demonstrate some
functions that will be included in the developed system.
Now, we will see the various steps involved in Prototyping.
• Requirements Definition/Collection. It is Similar to the Conceptualization phase of the
Waterfall Model, but not as comprehensive. The information collected is usually limited to a
subset of the complete system requirements.
• Design. Once the initial layer of requirements information is collected, or new information is
gathered, it is rapidly integrated into a new or existing design so that it may be folded into the
prototype.
• Prototype Creation/Modification. The information from the design is rapidly rolled into a
prototype. This may mean the creation/modification of paper information, new coding, or
modifications to existing coding.
• Assessment. The prototype is presented to the customer for review. Comments and suggestions
are collected from the customer.
• Prototype Refinement. Information collected from the customer is digested and the prototype is
refined. The developer revises the prototype to make it more effective and efficient.
• System Implementation. In most cases, the system is rewritten once requirements are
understood. Sometimes, the Iterative process eventually produces a working system that can be
the cornerstone for the fully functional system.
Problems associated with the Prototyping Model

Like other methods, prototyping is also having the following problems.
• Prototyping can lead to false expectations. Prototyping often creates a situation where the
customer mistakenly believes that the system is “finished” when in fact it is not. More
specifically, when using the Prototyping Model, the pre-implementation versions of a system are
really nothing more than one-dimensional structures. The necessary, behind the-scenes work such
as database normalization, documentation, testing, and reviews for efficiency have not been done.
Thus the necessary underpinnings for the system are not in place.
• Prototyping can lead to poorly designed systems. Because the primary goal of Prototyping is
rapid development, the design of the system can sometimes suffer because the system is built in a
series of “layers” without a global consideration of the integration of all other components.
Variation of the Prototyping Model
A popular variation of the Prototyping Model is called Rapid Application Development
(RAD). RAD introduces strict time limits on each development phase and relies heavily on rapid
application tools which allow for quick development.
3.6.5 The Exploratory Model

In some situations it is very difficult, if not impossible, to identify any of the requirements for a
system at the beginning of the project. Theoretical areas such as Artificial Intelligence are candidates for
using the Exploratory Model, because much of the research in these areas is based on guess-work,
estimation, and hypothesis. In these cases, an assumption is made as to how the system might work and

then rapid iterations are used to quickly incorporate suggested changes and build a usable system. A
distinguishing characteristic of the Exploratory Model is the absence of precise specifications. Validation
is based on adequacy of the end result and not on its adherence to pre-conceived requirements.
The Exploratory Model is extremely simple in its construction; it is composed of the following
steps:
• Initial Specification Development. Using whatever information is immediately available, a brief
System Specification is created to provide a rudimentary starting point.
• System Construction/Modification. A system is created and/or modified according to whatever
information is available.
• System Test. The system is tested to see what it does, what can be learned from it, and how it
may be improved.
• System Implementation. After many iterations of the previous two steps produce satisfactory
results, the system is dubbed as “finished” and implemented.
Problems associated with the Exploratory Model

There are numerous criticisms of the Exploratory Model:
• It is limited to use with very high-level languages that allow for rapid development, such as LISP.
• It is difficult to measure or predict its cost-effectiveness.
• As with the Prototyping Model, the use of the Exploratory Model often yields inefficient or
crudely designed systems, since no forethought is given as to how to produce a streamlined
system.
3.6.6 The Spiral Model

The Spiral Model was designed to include the best features from the Waterfall and Prototyping
models, and introduces a new component - risk-assessment. The term “spiral” is used to describe the
process that is followed as the development of the system takes place. Similar to the Prototyping Model,
an initial version of the system is developed, and then repetitively modified based on input received from
customer evaluations. Unlike the Prototyping Model, however, the development of each version of the
system is carefully designed using the steps involved in the Waterfall Model. With each iteration around
the spiral (beginning at the center and working outward), progressively more complete versions of the
system are built.
Risk assessment is included as a step in the development process as a means of evaluating each
version of the system to determine whether or not development should continue. If the customer decides
that any identified risks are too great, the project may be halted. For example, if a substantial increase in
cost or project completion time is identified during one phase of risk assessment, the customer or the
developer may decide that it does not make sense to continue with the project, since the increased cost or
lengthened timeframe may make continuation of the project impractical or unfeasible.
The Spiral Model is made up of the following steps:
• Project Objectives. Objectives are Similar to the system conception phase of the Waterfall
Model. Objectives are determined, possible obstacles are identified and alternative approaches are
weighed.
• Risk Assessment. Possible alternatives are examined by the developer, and associated
risks/problems are identified. Resolutions of the risks are evaluated and weighed in the
consideration of project continuation. Sometimes prototyping is used to clarify needs.
Engineering & Production. Detailed requirements are determined and the software piece is
developed.
• Planning and Management. The customer is given an opportunity to analyze the results of the
version created in the Engineering step and to offer feedback to the developer.
Problems associated with the Spiral Model

Due to the relative newness of the Spiral Model, it is difficult to assess its strengths and
weaknesses. However, the risk assessment component of the Spiral Model provides both developers and
customers with a measuring tool that earlier Process Models do not have. The measurement of risk is a
feature that occurs everyday in real-life situations, but (unfortunately) not as often in the system
development industry. The practical nature of this tool helps to make the Spiral Model a more realistic
Process Model than some of its predecessors.
3.6.7 The Reuse Model

The basic premise behind the Reuse Model is that systems should be built using existing
components, as opposed to custom-building new components. The Reuse Model is clearly suited to
Object-Oriented computing environments, which have become one of the premiere technologies in
today’s system development industry.
Within the Reuse Model, libraries of software modules are maintained that can be copied for use
in any system. These components are of two types: procedural modules and database modules. When
building a new system, the developer will “borrow” a copy of a module from the system library and then
plug it into a function or procedure. If the needed module is not available, the developer will build it, and
store a copy in the system library for future usage. If the modules are well engineered, the developer with
minimal changes can implement them.
The Reuse Model consists of the following steps:
• Definition of Requirements. Initial system requirements are collected. These requirements are
usually a subset of complete system requirements.
• Definition of Objects. The objects, which can support the necessary system components, are
identified.
• Collection of Objects. The system libraries are scanned to determine whether or not the needed
objects are available. Copies of the needed objects are downloaded from the system.
• Creation of Customized Objects. Objects that have been identified as needed, but that are not
available in the library are created.
• Prototype Assembly. A prototype version of the system is created and/or modified using the
necessary objects.
• Prototype Evaluation. The prototype is evaluated to determine if it adequately addresses
customer needs and requirements.
• Requirements Refinement. Requirements are further refined as a more detailed version of the
prototype is created.
• Objects Refinement. Objects are refined to reflect the changes in the requirements.
Problems Associated with the Reuse Model

A general criticism of the Reuse Model is that it is limited for use in object-oriented development
environments. Although this environment is rapidly growing in popularity, it is currently used in only a
minority of system development applications.
After seeing the various approaches and alternatives of System Development, now we can discuss
how to combine two are more models in Developing a System. This will help us to overcome the
problems associated with individual models.
3.7 Creating and Combining Models
In many cases, parts and procedures from various Process Models are integrated to support
system development. This occurs because most models were designed to provide a framework for
achieving success only under a certain set of circumstances. When the circumstances change beyond the
limits of the model, the results from using it are no longer predictable. When this situation occurs it is

sometimes necessary to alter the existing model to accommodate the change in circumstances, or adopt or
combine different models to accommodate the new circumstances.
The selection of an appropriate Process Model hinges primarily on two factors: organizational
environment and the nature of the application. Frank Land, from the London School of Economics,
suggests that suitable approaches to system analysis, design, development, and implementation be based
on the relationship between the information system and its organizational environment.
There are four categories of relationships are identified which I am explaining below:
• The Unchanging Environment. Information requirements are unchanging for the lifetime of the
system (e.g. those depending on scientific algorithms). Requirements can be stated
unambiguously and comprehensively. A high degree of accuracy is essential. In this environment,
formal methods (such as the Waterfall or Spiral Models) would provide the completeness and
precision required by the system.
• The Turbulent Environment. The organization is undergoing constant change and system
requirements are always changing. A system developed on the basis of the conventional Waterfall
Model would be, in part; already obsolete by the time it is implemented. Many business systems
fall into this category. Successful methods would include those, which incorporate rapid
development, some throwaway code (such as in Prototyping), the maximum use of reusable code,
and a highly modular design.
• The Uncertain Environment. The requirements of the system are unknown or uncertain. It is not
possible to define requirements accurately ahead of time because the situation is new or the
system being employed is highly innovative. Here, the development methods must emphasize
learning. Experimental Process Models, which take advantage of prototyping and rapid
development, are most appropriate.
• The Adaptive Environment. The environment may change in reaction to the system being
developed, thus initiating a changed set of requirements. Teaching systems and expert systems
fall into this category. For these systems, adaptation is key, and the methodology must allow for a
straightforward introduction of new rules.
So far, we have discussed about the various models and approaches in System Development.
Most of the models are developed around the basic activities in System Development what we have seen
earlier. Now, for clear and complete understanding we will see them in detail.
3.7.1 Problem Detection, Initial Investigation, Feasibility Study
The system development cycle is driven by the realization that there are deficiencies in the
system and these problems need to be addressed. A problem is a gap (variance) between expectation and
reality; variance is large enough that it falls outside defined tolerance limits, and therefore is worth the
effort/resources/cost needed to be expended to fix it.
There are two major problems for which we could do system development.
• Maintenance: on an existing system
• Development: building a new or replacement system
If the development cycle is driven by the detection of problems, how do we detect them?
When we observe:
• lack of relevancy lack of completeness lack of correctness (accuracy)
• lack of security lack of timeliness lack of economy
• lack of efficiency lack of reliability lack of usability
• throughput: number of error-free transactions per unit of time.
How do we observe these things?
• users may tell us (complaints)
• take surveys (e.g., questionnaires)
• managers may tell us (complaints)
• audits by outsiders

• we can ask (scouting)

• lower sales, loss of revenue
• continuous measurement of variances (TQM approach)
The purpose of the Initial Investigation is to make a recommendation:
• Take no action. (not a valid problem)
• Provide training/instruction/information to the end user to resolve the problem.
• Defer action to later. (adding an enhancement rather than fixing a deficiency)
• Do Maintenance to correct minor problem.
• Consider major modification or system replacement.
As a systems analyst, you must be able to handle project initiation, determine project feasibility
and project scheduling, and manage activities and systems analysis team members.
Feasibility study
There are few questions which we can answer through feasibility study
• Is the proposed project worth doing?
• Is it possible to do?
For answering these questions Feasibility Study has to be done in the following kinds.
• economic feasibility (cost-benefit analysis) (tangible economic benefit)
• technical feasibility
• operational/social feasibility
A feasibility study assesses the economic, technical, and operational merits of the proposed
project. A project is economically feasible if costs do not overshadow benefits. A project is technically
feasible if the technology is available and capable of meeting users' requests. A project is operationally
feasible if the proposed system will operate and be used once it is installed.
Important criteria for project selection are:
• that the requested project be backed by management
• that it be timed appropriately for commitment of resources (adequate time frame)
• that it moves the business toward attainment of its goals
• that it is practicable (adequate resources on the part of the analyst and the organization)
• that it is important enough to be considered over other projects (worthiness of the project)
What are the objectives of the proposed project? Acceptable objectives include
• reduce errors/improve accuracy
• reduce costs
• integrate subsystems: reduce complexity, streamline processes, combine processes
• shorten time requirements (speed up processes)
• reduce redundancy in storage, output
• improve customer service
• automate manual processes in support of the above
Unacceptable objectives include
• Ego-related (personal or organizational ego)
• To gain power
• To gain respect, admiration
• "Because it's Cool!"
• Automation for automation's sake alone
Information Gathering
After done the feasibility study, we can realize whether the project or proposed system is feasible
to be developed. Then, the next step is to collect information required for developing the new system.
This particular activity will be done with an objective of the available data and the future requirements of
the organisation to be collected. This can be done by employing the following methods:
Interviews
• a planned, formal, scheduled meeting. (make an appointment)

• Used to gather information.

• Interactive, flexible, adaptable, flexible.
• Time consuming; non-standardized responses may be difficult to evaluate.
• The interviewer should have basic objectives.
• Explain objectives to subject.
• Give subject time to prepare.
• Interview should be held in subject's own office or department.
• Interviewer comments should be noncommittal; neutral, non-leading questions.
• Avoid premature conclusions, selective perception.
• Be careful not to accept negative responses too readily.
• Beware of subjects who try too hard to please.
• Listen!!
Questionnaires
• Impersonal, often mass-produced.
• Response rate may be low (discarded and not returned).
• Suitable when number of respondents is large.
• Cheaper, faster than interviewing when number of respondents is large.
• Useful when the same information is required from all respondents.
• produces specific, limited accounts of information.
• If the population is very large, it can be sampled.
• Samples must be random, not convenient.
• Same information can be sought in different ways through multiple questions.
• Redundant questions can be compared for consistency of information/responses.
• Standardized responses: fill-in-the-blank, multiple choice, rating scales, rankings.
• Open-ended responses: more difficult to tabulate
• Standardized responses can be tabulated rapidly and analyzed using statistical distribution
techniques.
Observation
• A qualified person watches, or walks through, the actual processing associated with the system.
• Performance of the people being observed may be affected by the presence of the observer.
• Avoid taking notes: can affect the process performance if workers notice notes are being taken.
• Information gathered relates directly to observed performance: facts, not opinion.
Reviewing Existing Documentation
• Often there is little to tell you what is happening within the current information system.
• Keeping documentation up to date is not always a high organizational priority. Documentation
may be out of date.
• Many organizations have undocumented/informal procedures. (Formal organization chart vs.
what is really happening)
The Work Environment
• Physical arrangement of work areas will provide additional details associated with work flows
and job performance.
• Information gathered should describe the physical movement of documents, forms, people, or
transmitted data within offices where work is done.
• One method is to depict the floor plan of the office and trace the work flow onto it.
• New systems may disrupt existing work flows.
• Human factors: personal relationships may have developed around existing work flows.
Direct and Indirect Probes
• Direct probe (e.g., questionnaires, interviews, in-person observation)
• Indirect probe (review existing documentation; taking random samples)

Why indirect probes? Measurement itself can affect what is being measured. Direct investigation
can be an interruption to the process or a distraction. Human factors: direct (overt) observation can impact
on the performance of the workers.
3.7.2 System Analysis
In order to prepare the systems proposal in an effective way, systems analysts must use a
systematic approach to identify hardware and software needs – ascertaining hardware and software needs,
identifying and forecasting costs and benefits, comparing costs and benefits, and choosing the most
appropriate alternative.
In ascertaining hardware and software needs, systems analysts may take the following steps:
1. Inventory computer hardware already available in the organization.
2. Estimate both current and projected workload for the system.
3. Evaluate the performance of hardware and software using some predetermined criteria.
4. Choose the vendor according to the evaluation.
5. Acquire the hardware and software from the selected vendor.
When inventorying computer hardware, systems analysts should check such items as type of
equipment, status of the equipment (on order, in use, in storage, in need of repair), estimated age of
equipment, projected life of equipment, physical location of equipment, department or individual
responsible for equipment, and financial arrangement for equipment (owned, leased, rented).
When evaluating hardware, the involved persons, including management, users, and systems
analysts, should take the following criteria into consideration: time required for average transactions
(including time for input and output), total volume capacity of the system, idle time of the central
processing unit, and size of memory provided.
When evaluating hardware vendors, the selection committee needs to consider hardware support,
software support, installation and training support, maintenance support, and the performance of the
hardware.
When evaluating software packages, the selection committee needs to take the following factors
into consideration as well as total dollar amount to purchase them. They are: performance effectiveness,
performance efficiency, ease of use, flexibility, quality of documentation, and manufacturer support.
Systems analysts should take tangible costs, intangible costs, tangible benefits, and intangible
benefits into consideration to identify costs and benefits of a prospective system. To select the best
alternative, systems analysts should compare costs and benefits of the prospective alternatives.
Through the use of effectively organizing the content, writing in a professional style, and orally
presenting the proposal in an informative way, the analyst can create a successful systems proposal.
After analyzing all these aspects, now being a system analyst or a MIS manager, you have to
develop a System Proposal which comprises of the following:
1. Cover letter
2. Title page of project
3. Table of contents
4. Executive summary (including recommendation)
5. Outline of systems study with appropriate documentation
6. Detailed results of the systems study
7. Systems alternatives (3 or 4 possible solutions)
8. Systems analysts’ recommendations
9. Summary
10. Appendices (assorted documentation, summary of phases, correspondence, etc.)
When writing a systems proposal, systems analysts should use examples, illustrations, diagrams,
tables, figures, and graphs to support main points of the proposal.
Some guidelines for effective use of tables:
• Type only one table per page and integrate it into the body of the proposal.

• Try to fit the entire table vertically on a single page.

• Number and title the table at the top of the page. Make the title descriptive and meaningful.
• Label each row and column.
• Use a boxed table if room permits.
• Use an asterisk if necessary to explain detailed information contained in the table.
Some guidelines for the effective use of figures:
• Whenever possible, integrate the figure into the body of the proposal itself.
• Always introduce figures in the text before they appear.
• Always interpret figures in words; never leave them to stand on their own.
• Title all figures, label each axis, and provide legends where necessary.
• Use more than one figure if necessary, so that the visual does not become cluttered.
Some guidelines for effective use of graphs:
• Draw only one graph to a page unless you want to make a critical comparison between graphs.
• Integrate the graph into the body of the proposal.
• Give the graph a sequential figure number and a meaningful title.
• Label each axis, and any lines, columns, bars, and pieces of the pie on the graph.
• Include a key to indicate differently colored lines, shaded bars, or crosshatched areas.
Line graphs are used primarily to show change over time. Column charts can depict a comparison
between two or more variables over time, but more often they are used to compare different variables at a
particular point in time. Bar charts are used to show variables or variables within certain classes or
categories during a specific time period. Pie charts are used to show how 100 percent of a commodity is
divided at a particular point in time.
To make presentations more persuasive, the systems analyst may use white space, headings and
subheadings, effective page numbering style and position, relevant references and appendices.
Presentation software, such as Microsoft PowerPoint, is available that allows the analyst to use a
PC for a slide show. This allows the presentation to be enhanced by the use of clip art, video clips,
animation, and sound.
When delivering the oral presentation, systems analysts need to keep the following points in
mind:
• Project loudly enough so that the audience can hear you.
• Look at each person in the audience as you speak. (eye contact)
• Make visuals large enough so that the audience can see them.
• Use gestures that are natural to your conversational style.
• Introduce and conclude your talk confidently.
To overcome anxiety:
• Be yourself.
• Speak naturally.
• Breathe deeply before your presentation.
• Be prepared.
3.7.3 System Design and Modularity
Systems design is the evaluation of alternative solutions and the specification of a detailed
computer-based solution. It is also called physical design).
The key to understanding the design phase is to realize you are shifting your focus from
understanding the problem to figuring out a cost-effective solution to the problem. Design is especially
challenging because you usually have to devise a solution despite all sorts of constraints. For example,
you might be told the solution can’t cost more than $100,000, or that it must be implemented in 4 months,
or that it must run across the Win, Mac, and Unix platforms, etc.
You normally proceed with design in two major steps. First you need to determine a general
direction such as building a custom technology solution or buying a packaged one (general design).

Second you need to figure out all the details for going ahead with your general direction such as how to
integrate the purchased application into your existing environment or how to build it to meet requirements
in a way that minimizes cost of system over its full life cycle (detailed design). This includes both the cost
of initial implementation and much larger cost of long term support.
At this stage of Design, we should consider the following important concepts which will avoid
the flaws in our design. Majority of the system failures happening today are only due to the poor design
of systems.
• Modularity is important because: (1) it allows assignment of different programmers and analysts
to separate tasks; (2) small sections can be developed independently; and (3) maintenance causes
minimal disruption.
• Cohesion is how well activities within a single module are related to one another.
• Optimizing is the process of seeking the perfect solution. Satisfying is the process of seeking a
better, but not necessarily perfect, solution.
• There are no perfect systems. And, there are always constraints. So, satisfying, not optimizing is
the goal of system design.
Four categories of system flaws
• Major anticipated flaws are system functions that were not included in the design because of
constraints such as time or cost.
• Major unanticipated flaws are the most serious type of system shortcoming which indicates major
design and testing deficiencies.
• Minor unanticipated flaws are the most prevalent of system shortcomings and are handled by
maintenance.
• Minor anticipated flaws should not exist.
Three tactics to use for giving a system design a future orientation:
• Build redundancy into the current system.
• Maintain a future file on every system.
• Develop documentation.
After considering all these concepts, we could proceed with the system design which is
happening in two phases. The first part is to develop a blueprint of the system and to define the dataflow
and controls in the form of diagrams and other representations. After that we will write the computer
programs to physically create the system as software package. In this part we will design the form of
input, output and the user interface. Let us see them in brief below:
Logical design
• Produces a system blueprint
• General rather than technical format
Physical design
• Converts the blueprint into the specific detail required to construct the code
• Includes specifying complete descriptions of files, input, and output.
The systems blueprint may include charts, graphs, and data layouts that describe output
documents and reports, input documents that the system will process, computer records required to store
processed data, and the sequence and method by which output, input, and storage are linked. Output is the
primary purpose of any system. A senior systems analyst is usually in charge of project scheduling for
systems design in the case of small projects; a project leader for larger projects. Users should always
participate in the design phase because it fosters ownership. Clerical users should be involved in the
design of business information systems. At periodic intervals managers and supervisors should give their
stamp of approval.
The advantage of design teams is that design can be completed in modules. Structured
walkthroughs are valuable because they force the analyst to explain step-by-step logic of design; design
colleagues provide new ideas or spot flaws that the analyst has overlooked/not noticed; provides an
opportunity for analyst to practice explaining the system.

Joint Application Design (JAD) is the design of systems by groups of people meeting together in
multiple sessions. Design teams are cross-functional and include both users and designers. Designs are
completed more quickly with JAD than through traditional sequential methods. JAD involves a
significant amount of planning and coordination.
CASE design aids include: graphics (data flow diagrams, structure charts, etc.), screen and
document design, file design, rapid prototyping, and code generation.
Standard information systems are applicable across a wide range of industries. Tailored
information systems must match the specific characteristics of a firm or individual decision makers within
the firm. In the top-down approach the designer begins with the total concept and decomposes to further
levels of detail.
Modules
A module is a bounded contiguous group of statements having a single name and that can be
treated as a unit. In other words, a single block in a pile of blocks can be called as Module. Cohesion: how
well the activities within a single module relate to one another. Separate modules should be relatively
independent (loosely coupled). This facilitates development, maintenance by teams; reduces chance of
unintended ripple effects on other modules when changes made to a module.
Guidelines for Modularity
• Make sure modules perform a single task, have a single entry point, and have a single exit point.
• Isolate input-output (I-O) routines into a small number of standard modules that can be shared
system-wide.
• Isolate system-dependent functions (e.g., getting date or time) in the application to ease possible
future conversions to other computer platforms or to accommodate future operating system
revisions.
Any system always represents some kind of tradeoff between functionality (meeting the business
needs) and the resources available (constraints). The goal of design is an improved system, one that better
meets the needs of the organization.
Design: Input, Output, User Interface

Output Design
Output is the primary purpose of any system. These guidelines apply for the most part to both
paper and screen outputs. Output design is often discussed before other aspects of design because,
from the client's point of view, the output is the system. Output is what the client is buying when
he or she pays for a development project. Inputs, databases, and processes exist to provide output.
• Problems often associated with business information output are information delay, information
(data) overload, paper domination, excessive distribution, and no tailoring.
• Mainframe printers: high volume, high speed, located in the data center Remote site printers:
medium speed, close to end user.
• COM is Computer Output Microfilm. It is more compact than traditional output and may be
produced as fast as non-impact printer output.
• Turnaround documents reduce the cost of internal information processing by reducing both data
entry and associated errors.
• Periodic reports have set frequencies such as daily or weekly; ad hoc reports are produced at
irregular intervals.
• Detail and summary reports differ in the former support day-to-day operation of the business
while the latter include statistics and ratios used by managers to assess the health of operations.
• Page breaks and control breaks allow for summary totals on key fields.
• Report requirements documents contain general report information and field specifications; print
layout sheets present a picture of what the report will actually look like.
• Page decoupling is the separation of pages into cohesive groups.

• Two ways to design output for strategic purposes are (1) make it compatible with processes
outside the immediate scope of the system, and (2) turn action documents into turnaround
documents.
• People often receive reports they do not need because the number of reports received is perceived
as a measure of power.
• Fields on a report should be selected carefully to provide uncluttered reports, facilitate 80-column
remote printing, and reduce information (data) overload.
• The types of fields which should be considered for business output are: key fields for access to
information, fields for control breaks, fields that change, and exception fields.
• Output may be designed to aid future change by stressing unstructured reports, defining field size
for future growth, making field constants into variables, and leaving room on summary reports for
added ratios and statistics.
• Output can now be more easily tailored to the needs of individual users because inquiry-based
systems allow users themselves to create ad hoc reports.
• An output intermediary can restrict access to key information and prevent unauthorized access.
• An information clearinghouse (or information center) is a service center that provides
consultation, assistance, and documentation to encourage end-user development and use of
applications.
• The specifications needed to describe the output of a system are: data flow diagrams, data flow
specifications, data structure specifications, and data element specifications.
Output Documents
Printed Reports
• External Reports: for use or distribution outside the organization; often on preprinted forms.
• Internal Reports: for use within the organization; not as "pretty", stock paper, greenbar, etc.
• Periodic Reports: produced with a set frequency (daily, weekly, monthly, every fifth Tuesday,
etc.)
• Ad-Hoc (On Demand) Reports: irregular interval; produced upon user demand.
• Detail Reports: one line per transaction.
• Summary Reports: an overview.
• Exception Reports: only shows errors, problems, out-of-range values, or unexpected conditions or
events.
Input Design
• A source document differs from a turnaround document in that the former contains data that
change the status of a resource while the latter is a machine readable document.
• Transaction throughput is the number of error-free transactions entered during a specified
time period.
• A document should be concise because longer documents contain more data and so take longer to
enter and have a greater chance of data entry errors.
• Numeric coding substitutes numbers for character data (e.g., 1=male, 2=female); mnemonic
coding represents data in a form that is easier for the user to understand and remember. (e.g.,
M=male, F=female).
• The more quickly an error is detected, the closer the error is to the person who generated it and so
the error is more easily corrected.
• An example of an illogical combination in a payroll system would be an option to eliminate
federal tax withholding.
• By "multiple levels" of messages, I mean allowing the user to obtain more detailed explanations
of an error by using a help option, but not forcing a lengthy message on a user who does not want
it.

• An error suspense record would include the following fields: data entry operator identification,
transaction entry date, transaction entry time, transaction type, transaction image, fields in error,
error codes, date transaction reentered successfully.
• A data input specification is a detailed description of the individual fields (data elements) on an
input document together with their characteristics (i.e., type and length).
• Be specific and precise, not general, ambiguous, or vague.
(BAD: Syntax error, Invalid entry, General Failure)
• Don't JUST say what's wrong---- Be constructive; suggest what needs to be done to correct the
error condition.
• Be positive; Avoid condemnation. Possibly even to the point of avoiding pejorative terms such as
"invalid" "illegal" or "bad."
• Be user-centric and attempt to convey to the user that he or she is in control by replacing
imperatives such as "Enter date" with wording such as "Ready for date."
• Consider multiple message levels: the initial or default error message can be brief but allow the
user some mechanism to request additional information.
• Consistency in terminology and wording.
o place error messages in the same place on the screen
o use consistent display characteristics (blinking, color, beeping, etc.)
User Interface
• The primary differences between an interactive and batch environment are:
o interactive processing is done during the organization's prime work hours
o interactive systems usually have multiple, simultaneous users
o the experience level of users runs from novice to highly experienced
o developers must be good communicators because of the need to design systems with
error messages, help text, and requests for user responses.
• The seven step path that marks the structure of an interactive system is
1. Greeting screen (e.g., company logo)
2. Password screen -- to prevent unauthorized use
3. Main menu -- allow choice of several available applications
4. Intermediate menus -- further delineate choice of functions
5. Function screens -- updating or deleting records
6. Help screens -- how to perform a task
7. Escape options -- from a particular screen or the application
• An intermediate menu and a function screen differ in that the former provides choices from a set
of related operations while the latter provides the ability to perform tasks such as updates or
deletes.
• The difference between inquiry and command language dialogue modes is that the former asks
the user to provide a response to a simple question (e.g., "Do you really want to delete this file?")
where the latter requires that the user know what he or she wants to do next (e.g., MS-DOS C:>
prompt; VAX/VMS $ prompt; Unix shell prompt). GUI Interface (Windows, Macintosh) provide
Dialog Boxes to prompt user to input required information/parameters.
• Directions for designing form-filling screens:
o Fields on the screen should be in the same sequence as on the source document.
o Use cuing to provide the user with information such as field formats (e.g., dates)
o Provide default values.
o Edit all entered fields for transaction errors.
o Move the cursor automatically to the next entry field
o Allow entry to be free-form (e.g., do not make the user enter leading zeroes)
o Consider having all entries made at the same position on the screen.

• A default value is a value automatically supplied by the application when the user leaves a field
blank. For example, at SXU the screen on which student names and addresses are entered has a
default value of "IL" for State since the majority of students have addresses in Illinois. At one
time "312" was a default value for Area Code, but with the additional Area Codes now in use
(312, 773, 708, 630, 847) providing a default value for this field is no longer as useful.
• The eight parts of an interactive screen menu are:
0. Locator -- what application the user is currently in
1. Menu ID -- allows the more experienced user access without going through the entire
menu tree.
2. Title
3. User instructions
4. Menu list
5. Escape option
6. User response area
7. System messages (e.g., error messages)
• Highlighting should be used for gaining attention and so should be limited to critical information,
unusual values, high priority messages, or items that must be changed.
• Potential problems associated with the overuse of color are:
o Colors have different meanings to different people and in different cultures.
o A certain percentage of the population is known to have color vision deficiency.
o Some color combinations may be disruptive.
• Information density is important because density that is too high makes it more difficult to
discern the information presented on a screen, especially for novice users.
• Rules for defining message content include:
o Use active voice.
o Use short, simple sentences.
o Use affirmative statements.
o Avoid hyphenation and unnecessary punctuation.
o Separate text paragraphs with at least one blank line.
o Keep field width within 40 characters for easy reading.
o Avoid word contractions and abbreviations.
o Use non threatening language.
o Avoid godlike language.
o Do not patronize.
o Use mixed case (upper and lower case) letters.
o Use humor carefully.
• Symmetry is important to screen design because it is aesthetically pleasing and thus more
comforting.
• Input verification is asking the user to confirm his or her most recent input (e.g., "Are you sure
you want to delete this file?")
• Adaptive models are useful because they adapt to the user's experience level as he or she moves
from novice to experienced over time as experience with the system grows.
• "Within User" sources of variation include: warm up, fatigue, boredom, environmental
conditions, and extraneous events.
• The elements of the adaptive model are:
o Triggering question to determine user experience level
o Differentiation among user experience
o Alternative processing paths based on user level
o Transition of casual user to experienced processing path
o Transition of novice user to experienced processing path
o Allowing the user to move to an easier processing path

• Interactive tasks can be designed for closure by providing the user with feedback indicating that a
task has been completed.
• Internal locus of control is making users feel that they are in control of the system, rather than
that the system is in control of them.
• Examples of distracting use of surprise are:
o Highlighting
o Input verification
o Flashing messages
o Auditory messages
• Losing the interactive user can be avoided by using short menu paths and "You are here"
prompts.
• Some common user shortcuts are: direct menu access, function keys, and shortened response
time.
Golden Rules of Interface Design

• Strive for consistency.
• Enable frequent users to use shortcuts.
• Offer informative feedback.
• Design dialogs to yield closure.
• Offer error prevention and simple error handling.
• Permit easy reversal of actions.
• Support internal locus of control.
• Reduce short-term memory load.
3.7.4 Data Entry and Data Storage
The quality of data input determines the quality of information output. Systems analysts can
support accurate data entry through achievement of three broad objectives: effective coding, effective and
efficient data capture and entry, and assuring quality through validation. Coding aids in reaching the
objective of efficiency, since data that are coded require less time to enter and reduce the number of items
entered. Coding can also help in appropriate sorting of data during the data transformation process.
Additionally, coded data can save valuable memory and storage space.
In establishing a coding system, systems analysts should follow these guidelines:
• Keep codes concise.
• Keep codes stable.
• Make codes that are unique.
• Allow codes to be sortable.
• Avoid confusing codes.
• Keep codes uniform.
• Allow for modification of codes.
• Make codes meaningful.
The simple sequence code is a number that is assigned to something if it needs to be numbered.
It therefore has no relation to the data itself. Classification codes are used to distinguish one group of
data, with special characteristics, from another. Classification codes can consist of either a single letter or
number. The block sequence code is an extension of the sequence code. The advantage of the block
sequence code is that the data are grouped according to common characteristics, while still taking
advantage of the simplicity of assigning the next available number within the block to the next item
needing identification.
A mnemonic is a memory aid. Any code that helps the data-entry person remember how to enter
the data or the end-user remember how to use the information can be considered a mnemonic. Mnemonic
coding can be less arbitrary, and therefore easier to remember, than numeric coding schemes. Compare,

for example, a gender coding system that uses "F" for Female and "M" for Male with an arbitrary numeric
coding of gender where perhaps "1" means Female and "2" means Male. Or, perhaps it should be "1" for
Male and "2" for Female? Or, why not "7" for Male and "4" for Female? The arbitrary nature of numeric
coding makes it more difficult for the user.
Date Formats
An effective format for the storage of date values is the eight-digit YYYYMMDD format as it
allows for easy sorting by date. Note the importance of using four digits for the year. This eliminates any
ambiguity in whether a value such as 01 means the year 1901 or the year 2001. Using four digits also
insures that the correct sort sequence will be maintained in a group of records that include year values
both before and after the turn of the century (e.g., 1999, 2000, 2001).
Remember, however, that the date format you use for storage of a date value need not be the same
date format that you present to the user via the user interface or require of the user for data entry. While
YYYYMMDD may be useful for the storage of date values it is not how human beings commonly write
or read dates. A person is more likely to be familiar with using dates that are in MMDDYY format. That
is, a person is much more likely to be comfortable writing the date December 25, 2001 as "12/25/01" than
"20011225."
Fortunately, it is a simple matter to code a routine that can be inserted between the user interface
or data entry routines and the data storage routines that read from or write to magnetic disk. Thus, date
values can be saved on disk in whatever format is deemed convenient for storage and sorting while at the
same time being presented in the user interface, data entry routines, and printed reports in whatever
format is deemed convenient and familiar for human users.
Data Entry Methods
• keyboards
• optical character recognition (OCR)
• magnetic ink character recognition (MICR)
• mark-sense forms
• punch-out forms
• bar codes
• intelligent terminals
Tests for validating input data include: test for missing data, test for correct field length, test for
class or composition, test for range or reasonableness, test for invalid values, test for comparison with
stored data, setting up self-validating codes, and using check digits. Tests for class or composition are
used to check whether data fields are correctly filled in with either numbers or letters. Tests for range or
reasonableness do not permit a user to input a date such as October 32. This is sometimes called a sanity
check.
Database
A database is a group of related files. This collection is usually organized to facilitate efficient
and accurate inquiry and update. A database management system (DBMS) is a software package that is
used to organize and maintain a database.
Usually when we use the word "file" we mean traditional or conventional files. Sometimes we
call them "flat files." With these traditional, flat files each file is a single, recognizable, distinct entity on
your hard disk. These are the kind of files that you can see cataloged in your directory.
Commonly, these days, when we use the word "database" we are not talking about a collection of
this kind of file; rather we would usually be understood to be talking about a database management
system. And, commonly, people who work in a DBMS environment speak in terms of "tables" rather than
"files."
DBMS software allows data and file relationships to be created, maintained, and reported. A
DBMS offers a number of advantages over file-oriented systems including reduced data duplication,
easier reporting, improved security, and more rapid development of new applications.
The DBMS may or may not store a table as an individual, distinct disk file. The software may
choose to store more than one table in a single disk file. Or it may choose to store one table across several

distinct disk files, or even spread it across multiple hard disks. The details of physical storage of the data
is not important to the end user who only is concerned about the logical tables, not physical disk files.
In a hierarchical database the data is organized in a tree structure. Each parent record may have
multiple child records, but any child may only have one parent. The parent-child relationships are
established when the database is first generated, which makes later modification more difficult.
A network database is similar to a hierarchical database except that a child record (called a
"member") may have more than one parent (called an "owner"). Like in a hierarchical database, the
parent-child relationships must be defined before the database is put into use, and the addition or
modification of fields requires the relationships to be redefined.
In a relational database the data is organized in tables that are called "relations." Tables are
usually depicted as a grid of rows ("tuples") and columns ("attributes"). Each row is a record; each
column is a field. With a relational database links between tables can be established at any time provided
the tables have a field in common. This allows for a great amount of flexibility.
3.7.5 System Implementation
Systems implementation is the construction of the new system and its delivery into ‘production’
or day-to-day operation.
The key to understanding the implementation phase is to realize that there is a lot more to be done
than programming. During implementation you bring your process, data, and network models to life with
technology. This requires programming, but it also requires database creation and population, and
network installation and testing. You also need to make sure the people are taken care of with effective
training and documentation. Finally, if you expect your development skills to improve over time, you
need to conduct a review of the lessons learned.
During both design and implementation, you ought to be looking ahead to the support phase.
Over the long run, this is where most of the costs of an application reside.
Systems implementation involves installation and changeover from the previous system to the
new one, including training users and making adjustments to the system. Many problems can arise at this
stage. You have to be extremely careful in implementing new systems. First, users are probably nervous
about the change already. If something goes wrong they may never trust the new system. Second, if major
errors occur, you could lose important business data.
A crucial stage in implementation is final testing. Testing and quality control must be performed
at every stage of development, but a final systems test is needed before staff entrust the company's data
to the new system. Occasionally, small problems will be noted, but their resolution will be left for later.
In any large system, errors and changes will occur, the key is to identify them and determine which ones
must be fixed immediately. Smaller problems are often left to the software maintenance staff.
Change is an important part of MIS. Designing and implementing new systems often causes
changes in the business operations. Yet, many people do, not like changes. Changes require learning new
methods, forging new relationships with people and managers, or perhaps even loss of jobs. Changes
exist on many levels: in society, in business, and in information systems. Changes can occur because of
shifts in the environment, or they can be introduced by internal change agents. Left to themselves, most
organizations will resist even small changes. Change agents are objects or people who cause or facilitate
changes. Sometimes it might be a new employee who brings fresh ideas; other times changes can be
mandated by top-level management. Sometimes an outside event such as arrival of a new competitor or a
natural disaster forces an organization to change. Whatever the cause, people tend to resist change.
However, if organizations do not change, they cannot survive. The goal is to implement systems in a
manner that recognizes resistance to change but encourages people to accept the new system. Effective
implementation involves finding ways to reduce this resistance. Sometimes, implementation involves the
cooperation of outsiders such as suppliers.
Because implementation is so important, several techniques have been developed to help
implement new systems. Direct cutover is an obvious technique, where the old system is simply dropped

and the new one started. If at all possible, it is best to avoid this technique, because it is the most
dangerous to data. If anything goes wrong with the new system, you run the risk of losing valuable
information because the old system is not available.
In many ways, the safest choice is to use parallel implementation. In this case, the new system is
introduced alongside the old one. Both systems are operated at the same time until you determine that the
new system is acceptable. The main drawback to this method is that it can be expensive because data has
to be entered twice. Additionally, if users are nervous about the new system, they might avoid the change
and stick with the old method. In this case, the new system may never get a fair trial.
If you design a system for a chain of retail stores, you could pilot test the first implementation in
one store. By working with one store at a time, there are likely to be fewer problems. But if problems do
arise, you will have more staff members around to overcome the obstacles. When the system is working
well in one store, you can move to the next location. Similarly, even if there is only one store, you might
be able to split the implementation into sections based on the area of business. You might install a set of
computer cash registers first. When they work correctly, you can connect them to a central computer and
produce daily reports. Next, you can move on to annual summaries and payroll. Eventually the entire
system will be installed.
Let us now see the Process of Implementation which involves the following steps:
• Internal or outsourcing (trend is "outsourcing")
• Acquisition: purchasing software, hardware, etc.
• Training: employee (end-users) training, technical staff training. SQL training in 5 days costs
around $2000, + airplane, hotel, meals, rental car ($3000 to 5000); evaluation
• Testing:
o a bigger system requires more testing time
o a good career opportunity for non-technical people who wish to get in the door in the
IT jobs.
• Documentation:
o backup
o knowledge management system
• Actual Installation
• Conversion: Migration from the old system to a new system
• Maintenance: very important; if you don't maintain the new system properly, it's useless to
develop a new system.
o monitor the system,
o upgrade,
o trouble-shooting,
o continuous improvement
3.7.6 System Maintenance
Once the system is installed, the MIS job has just begun. Computer systems are constantly
changing. Hardware upgrades occur continually, and commercial software tools may change every year.
Users change jobs. Errors may exist in the system. The business changes, and management and users
demand new information and expansions. All of these actions mean the system needs to be modified. The
job of overseeing and making these modifications is called software maintenance.
The pressures for change are so great that in most organizations today as much as 80 per cent of
the MIS staff is devoted to modifying existing programs. These changes can be time consuming and
difficult. Most major systems were created by teams of programmers and analysts over a long period. In
order to make a change to a program, the programmer has to understand how the current program works.
Because the program was written by many different people with varying styles, it can be hard to
understand. Finally, when a programmer makes a minor change in one location, it can affect another area
of the program, which can cause additional errors or necessitate more changes

One difficulty with software maintenance is that every time part of an application is modified,
there is a risk of adding defects (bugs). Also, over time the application becomes less structured and more
complex, making it harder to understand. These are some of the main reasons why the year 2000
alterations were so expensive and time consuming. At some point, a company may decide to replace or
improve the heavily modified system. There are several techniques for improving an existing system,
ranging from rewriting individual sections to restructuring the entire application.. The difference lies in
scope-how much of the application needs to be modified. Older applications that were subject to
modifications over several years tend to contain code that is no longer used, poorly documented changes,
and inconsistent naming conventions. These applications are prime candidates for restructuring, during
which the entire code is analyzed and reorganized to make it more efficient. More important, the code is
organized, standardized, and documented to make it easier to make changes in the future.
3.7.7 System Evaluation
An important phase in any project is evaluating the resulting system. As part of this evaluation, it
is also important to assess the effectiveness of the particular development process. There are several
questions to ask. Were the initial cost estimates accurate? Was the project completed on time? Did users
have sufficient input? Are maintenance costs higher than expected?
Evaluation is a difficult issue. How can you as a manager tell the difference between a good
system and a poor one? In some way, the system should decrease costs, increase revenue, or provide a
competitive advantage. Although these effects are important, they are often subtle and difficult to
measure. The system should also be easy to use and flexible enough to adapt to changes in the business. If
employees or customers continue to complain about a system, it should be reexamined. .
A system also needs to be reliable. It should be available when needed and should produce
accurate output. Error detection can be provided in the system to recognize and avoid common problems.
Similarly, some systems can be built to tolerate errors, so that when errors arise, the system recognizes the
problem and works around it. For example, some computers exist today that automatically switch to
backup components when one section fails, thereby exhibiting fault tolerance.
Managers concern to remember when dealing with new systems is that the evaluation mechanism
should be determined at the start. The question of evaluation is ignored until someone questions the value
of the finished product. It is a good design practice to ask what would make this system a good system
when it is finished or how we can tell a good system from a bad one in this application. Even though
these questions may be difficult to answer, they need to be asked. The answers, however incomplete, will
provide valuable guidance during the design stage.
Recall that every system needs a goal, a way of measuring progress toward that goal, and a
feedback mechanism. Traditionally, control of systems has been the task of the computer programming
staff. Their primary goal was to create error-free code, and they used various testing techniques to find
and correct errors in the code. Today, creating error-free code is not a sufficient goal.
We have all heard the phrase, "The customer is always right." The meaning behind this phrase is
that sometimes people have different opinions on whether a system is behaving correctly. When there is a
conflict, the opinion that is most important is that of the customer. In the final analysis, customers are in
control because they can always take their business elsewhere. With information systems, the users are
the customers and the users should be the ones in control. Users determine whether a system is good. If
the users are not convinced that the system performs useful tasks, it is not a good system.

3.8 Strengths and Weaknesses of SDLC
The primary purpose of the SDLC method of designing systems is to provide guidance and
control over the development process. As summarized in the following table, there are strengths and
weaknesses to this methodology. SDLC management control is vital for large projects to ensure that the
individual teams work together. There are also financial controls to keep track of the project expenses.
The SDLC steps are often spelled out in great detail. The formality makes it easier to train employees and
to evaluate the progress of the development. It also ensures that steps are not skipped, such as user
approval, documentation, and testing. For large, complex projects, this degree of control is necessary to
ensure the project can be completed. Another advantage of SDLC is that by adhering to standards while
building the system, programmers will find the system easier to modify and maintain later. The internal
consistency and documentation make it easier to modify. With 80 percent of MIS resources spent on
maintenance, this advantage can be critical.
In some cases the formality of SDLC causes problems. Most important, it increases the cost of
development and lengthens the development time. Remember that often less than 25 percent of the time is
spent on actually writing programs. A great deal of the rest of the time is spent filling out forms and
drawing diagrams
The formality of the SDLC also causes problems with projects that are hard to define. SDLC
works best if the entire system can be accurately specified in the beginning. That is, users and managers
need to know exactly what the system should do long before the system is created. That is not a serious
problem with transaction-processing systems. However, consider the development of a complex decision
support system. Initially, the users may not know how the system can help. Only through working with
the system on actual problems will they spot errors and identify enhancements.
Although some large projects could never have been completed without SDLC, its rigidity tends
to make it difficult to develop many modern applications. Additionally, experience has shown that it has
not really solved the problems of projects being over budget and late. As a result of this criticism, many
people are searching for alternatives. One possibility is to keep the basic SDLC in place and use
technology to make it more efficient. Other suggestions have been to replace the entire process with a
more efficient development process, such as prototyping. Consider the assistance of technology first

3.9 Summary
The evolution of system development Process Models has reflected the changing needs of
computer customers. As customers demanded faster results, more involvement in the development
process, and the inclusion of measures to determine risks and effectiveness, the methods for developing
systems changed. In addition, the software and hardware tools used in the industry changed (and continue
to change) substantially. Faster networks and hardware supported the use of smarter and faster operating
systems that paved the way for new languages and databases, and applications that were far more
powerful than any predecessors. Numerous changes in the system development environment
simultaneously spawned the development of more practical new Process Models and the demise of older
models that were no longer useful.

UNIT I
Lesson 4 – Managing Data Resources
Learning Objectives
• To analyse the reasons for organisations having trouble in finding their required information.
• To understand the benefits of database management system in .improving the organisation of
information
• To learn the various types of database models affecting the way a business can access and use
information
• To know about the requirements of a database environment
4.1 Introduction
Effective use of information depends on how data are stored, organised and accessed in an
organisation. Proper delivery of information not only depends upon the capabilities of computer hardware
and software but also on the organisation’s ability to manage data as an important resource. After seeing the
various methods and approaches of System Development, now, let us have some understanding of how
important are the data resources in an organisation and how the information system we developed is going to
handle them.
It has been very difficult for organizations to manage their data effectively. In trying to do so, we
have to meet two very big challenges which are standing out. Implementing a database requires a widespread
organisational change in the role of information and information managers, the allocation of power al senior
levels, the ownership and sharing of information, and patterns of organisational agreement. A database
management system (DBMS) challenges the existing power arrangements in an organisation and for that
reason often generate political resistance. In a traditional file environment, each department constructed files
and programs to fulfill its specific needs. Now, with a database, files and programs must be built that take
into account the full organization’s interest in data. Although the organisation has spent the money on
hardware and software for a database environment, it may not reap the benefits it should if it is unwilling to
make the requisite organisational changes.
Moving to database environment can be a costly long-term process. In addition to the cost of DBMS
Software, related hardware, and data modeling, organizations should anticipate heavy expenditure for
integrating, merging and standardizing their data that will populate their database to eliminate
inconsistencies, redundancies and errors that typically arise when overlapping data are stored and maintained
by different systems and different functional areas.
You should understand the managerial and organisational requirements as well as the technologies
for managing data as a resource. Organizations need to manage their data assets very carefully to make sure
that the data can be easily accessed and managed by the managers and employees across the organisation.
First, we describe the typical challenges facing business trying to access information using
traditional file management technologies. Then we describe the technology of database management
systems, which can overcome many of the drawbacks of traditional file management systems and provide the
firm wide integration of information required for digital firm applications.
4.2 Organizing Data in a Traditional File Environment
Information is becoming as important a business resource as money, material, and people.

Businesses are realizing the competitive advantage they can gain over their competition through useful
information, not just data.
Why should you know about organizing data? Because it's almost inevitable that some day you'll be
establishing or at least working with a database of some kind. As with anything else, understanding the lingo

is the first step to understanding the whole concept of managing and maintaining information. It all comes
down to turning data into useful information, not just a bunch of bits and bytes.
4.2.1 File Organization Terms and Concepts
The data hierarchy in traditional file management system
The first few terms, field, record, file, database, are depicted in Figure 8.1, which shows the
relationship between them.
An entity is basically the person, place, thing, or event about which we maintain information. Each
characteristic or quality describing an entity is called an attribute. Each record requires a key field, or
unique identifier. The best example of this is your PAN Number: there is only one per person. That explains
in part why so many companies and organizations ask for your PAN Number when you do business with
them.
Suppose you decide to create a database for your newspaper delivery business. To succeed, you need
to keep accurate, useful information for each of your customers. You set up a database to maintain the
information. For each customer, you create a record. Within each record you have the following fields:
customer name, address, ID, date last paid. Smith, Jones, and Brooks are the records within a file you decide
to call Paper Delivery. The entities then are Smith, Jones, and Brooks, the people on whom you are
maintaining information. The attributes are customer name, address, ID, and date last paid. The key field in
this file is the ID number; perhaps you'll use their phone number, since it will be unique for each record. This
is a simplistic example of a database, but it should help you understand the terminology.
4.2.2 Accessing Records

When we were describing secondary storage, we talked about magnetic tape and disk storage for
computer data. To understand how information is accessed from these mediums, think about the difference
between a music cassette tape and a music CD. If you want to get to a particular song on a cassette tape, you
must pass by all the other songs sequentially. If you want to get to a song on CD, you can go directly to that
song without worrying about any of the others. That is the difference between sequential and direct access
organization for database records.
Sequential file organization, in conjunction with magnetic tape, is typically used for processing the
same information on all records at the same time. It is also good for processing many records at once,
commonly called batch processing.
Direct or random file organization is used with magnetic disks. Because of increased speed and
improved technological methods of recording data on disks, many companies now use disks instead of tapes.
The other advantage that disks have over tapes is that disks don't physically deteriorate as fast as tapes do.
There is less danger of damaging the surface of the disks than there is of breaking a tape.
Indexed Sequential Access Method

To explain the indexed sequential access method (ISAM), let's go back to the example of the
cassette tape. A cassette tape label has a printed list of the songs contained on it which gives you a general
idea of where to go on the tape to find a particular tune. So too with computer records on a sequential access
tape using the key field. It gives the computer a pretty accurate idea of where a particular record is located.
That's why it's so a important to have a unique ID as the key field. You and your customer could have a
difficult time if the key field is duplicated among several records. Each key field and the ultimate location of
that record on the storage device is maintained in the index.
Direct file access method

This access method also uses key fields in combination with mathematical calculations to determine
the location of a record. If you order something by phone from a mail order catalog, the person taking your
order does not have to wait for the computer to randomly select your record; using the direct file access
method, the computer can find you very quickly.
Here, you van understand that the records are not stored sequentially but at random. The transform
algorithm uses the value in the key field to find the storage location and access the record.
4.2.3 Problems with the Traditional File Environment
Many problems, such as data redundancy, program-data dependence, inflexibility, poor data security,
and inability to share data among applications, have occurred with traditional file environments.
We've spoken about "islands of information" before. Building and maintaining databases is where
this situation is most evident and most troublesome. Usually it begins in all innocence, but it can quickly
grow to monstrous proportions.
For instance, after you move and change addresses, you notify everyone of your new address,
including your bank. Everything is going smoothly with your monthly statements. All of a sudden, at the end
of the year, the bank sends a Christmas card to your old address. Why? Because your new address was
changed in one database, but the bank maintains a separate database for its Christmas card list and your
address was never changed in it.
If you received two Christmas cards, you're probably a victim of data redundancy. That is, your
information is now in two separate databases with duplicate records. In this instance, each database file has
different data on the same record. That can be a nightmare on Main Street.
Even more troublesome is when several departments or individuals decide to set up their own islands
of information. This usually happens because they find the main system inflexible or it just doesn't fit their
needs. So they set up their own fields and records and files and use them in their own programs to manipulate
data according to their needs. Now each department is spending dollars and time to establish and maintain
separate islands of information.

Even worse, the fields and records for Marketing probably don't have the same structure and
meaning as the fields and records for Accounting, or those for Production. Each record describes basically
the same entity (customers or products), but it is very possible that each database file will have different
information, or attributes, in records concerning the same entity.
All of this may have happened with the best of intentions. All the departments began with the goal of
making their part of the organization more efficient. Eventually these good intentions can cost big dollars to
bring the islands together, resolve data conflicts between them, and retrain people to understand the new
database structures.
Managers and workers must know and understand how databases are constructed so they know how
to use the information resource to their advantage. Managers must guard against problems inherent with
islands of information and understand that sometimes resolution of short-term problems is far costlier in the
long term.
4.3 Database Management Systems
The key to establishing an effective, efficient database is to involve the entire organization as much
as possible, even if everyone seemingly will not be connected to it or be a user of it. Perhaps they won't be a
part of it in the beginning, but they very well could be later on.
You've heard the old saying, "Don't put all your eggs in one basket." When it comes to data, just the
opposite is true. You want to put all your corporate data in one system that will serve the organization as a
whole. A Database Management System (DBMS) is basically another software program like Word or Excel
or Email. This type of software is more complicated: it permits an organization to centralize data, manage
them efficiently, and provide access to the stored data by application programs.
A DBMS has 3 components, all of them important for the long-term success of the system.
• Data Definition Language (DDL). Marketing looks at customer addresses differently from
Shipping. So you must make sure that all users of the database are speaking the same language.
Think of it this way: Marketing is speaking French, Production is speaking German, and Human
Resources is speaking Japanese. They are all saying the same thing, but it's very difficult for them to
understand each other. Defining the data definition language itself sometimes gets shortchanged. The
programmers who are creating the language sometimes say "Hey, an address is an address, so what."
That's when it becomes critical to involve users in the development of the Data Definition Language.
• Data Manipulation Language (DML). This is a formal language used by programmers to
manipulate the data in the database and make sure they are formulated into useful information. The
goal of this language should be to make it easy for users. The basic idea is to establish a single data
element that can serve multiple users in different departments depending on the situation. Otherwise,
you'll be tying up programmers to get information from the database that users should be able to get
on their own.
• Data Dictionary. Each data element or field should be carefully analyzed to determine what it will
be used for, who will be the primary user, and how it fits into the overall scheme of things. Then
write it all down and make it easily available to all users. This is one of the most important steps in
creating a good database.
Why is it so important to document the data dictionary? Let's say Suvidha, who was in on the initial
design and building of the database, moves on and Joe takes her place. It may not be so apparent to him what
all the data elements really mean, and he can easily make mistakes from not knowing or understanding the
correct use of the data. He will apply his own interpretation, which may or may not be correct. Once again, it
ultimately comes down to a persware problem.
4.3.1 Logical and Physical Views of Data
Physical views of items are often different from the logical views of the same items when they are
actually being used. For instance, assume you store tablets of paper in your lower right desk drawer. You

store your pencils in the upper left drawer. When it comes time to write your request for a pay raise, you pull
out the paper and pencil and put them together on your desktop. It isn't important to the task at hand where
the items were stored physically; you are concerned with the logical idea of the two items coming together to
help you accomplish the task.
The physical view of data cares about where the data are actually stored in the record or in a file. The
physical view is important to programmers who must manipulate the data as they are physically stored in the
database.
Does it really matter to the user that the customer address is physically stored on the disk before the
customer name? Probably not. However, when users create a report of customers located in Indiana they
generally will list the customer name first and then the address. So it's more important to the end user to
bring the data from their physical location on the storage device to a logical view in the output device,
whether screen or paper.
Database Management Systems have three critical components: the data definition language, the data
manipulation language, and the data dictionary. Managers should ensure that all three receive attention.
Managers should also make sure that end users are involved in developing these three components.
4.3.2 Designing Databases
Every tool has its job. You wouldn't use a screwdriver to pound a nail in the wall (or maybe you
would), nor would you use a hammer to turn a bolt. Each type of database that we discuss in this section has
its own advantages and disadvantages, so you should choose the right type of database for the job you want
to do.
Hierarchical Databases
The hierarchical data model presents data to users in a treelike structure.
Think of a mother and her children. A child only has one mother and inherits some of her
characteristics, such as eye color or hair color. A mother might have one or more children to which she
passes some of her characteristics but usually not exact ones. The child then goes on to develop its own
characteristics separate from the mother.
A hierarchical database for a human resources system.
In a hierarchical database, characteristics from the parent are passed to the child by a pointer just as
a human mother will have a genetic connection to each human child. You can see how this database pointer
works by looking at the above figure..
Network Database

A network data model is a variation of the hierarchical model.
Take the same scenario with one parent and many children and add a father and perhaps a couple of
stepparents. Now the parents aren't restricted to only one (the mother) but to many parents. That is, a parent
can have many children and a child can have many parents. The parents pass on certain characteristics to the
children, but the children also have their own distinct characteristics.
The network data model.
As with hierarchical structures, each relationship in a network database must have a pointer from all
the parents to all the children and back, as the above figure demonstrates.
These two types of databases, the hierarchical and the network, work well together since they can
easily pass data back and forth. But because these database structures use pointers, which are actually
additional data elements, the size of the database can grow very quickly and cause maintenance and
operation problems.
Relational Data Model
A relational data model uses tables in which data are stored to extract and combine data in different
combinations. The tables are sometimes called files, although that is actually a misnomer, since you can have
multiple tables in one file.
In a relational database, each table contains a primary key, a unique identifier for each record. To
make sure the tables relate to each other, the primary key from one table is stored in a related table as a
secondary key. For instance, in the Customer table the primary key is the unique Customer ID. That primary
key is then stored in the Order Table as the secondary key so that the two tables have a direct relationship.
Customer Table Order Table

Order Number Primary Key
Customer Name Self Explanatory Order Item Self Explanatory
Customer Address Self Explanatory Number of Items Ordered Self Explanatory
Customer ID Primary Key-----> Customer ID Secondary Key
Order Number Secondary Key
Use these three basic operations to develop relational databases:

• Select: create a subset of records meeting the stated criteria
• Join: combine related tables to provide more information than individual tables

• Project: create a new table from subsets of previous tables
The biggest problem with these databases is the misconception that every data element should be stored
in the same table. In fact, each data element should be analyzed in relation to other data elements with the
goal of making the tables as small in size as possible. The ideal relational database will have many small
tables, not one big one. On the surface that may seem like extra work and effort, but by keeping the tables
small, they can serve a wider audience because they are more flexible. This setup is especially helpful in
reducing redundancy and increasing the usefulness of data.
Advantages and Disadvantages
Hierarchical and network databases can be very efficient as long as you plan ahead. But as you
know, needs change, and neither one of these databases offers a lot of flexibility to change with business
needs. It's sort of like parents and children; once you establish the tie, it's pretty hard to amend.
Relational database management systems are more flexible, especially if you keep the tables small. It
is much easier for non-techies to create the query language in a relational system. It's also easier to add new
data elements, although if you do, you'll have to go back and fill in the missing information for the old
records or just forget them altogether.
4.3.3 Comparing of Database Alternatives

Improving
The above table compares these alternatives on several dimensions to show you the advantages and
disadvantages of each.
What you should remember is that none of these databases is very good if you don't keep the end
user in mind. If you're not careful, you'll wind up with lots of information that no one can use.
4.3.4 Creating a database
First, you should think long and hard about how you use the available information in your current
situation. Think of the good and the bad of how it is organized, stored, and used. Now imagine how this
information could be organized better and used more easily throughout the organization. What part of the
current system would you be willing to get rid of and what would you add? Involve as many users in this
planning stage as possible. They are the ones who will prosper or suffer because of the decisions you make at
this point.
Determine the relationships between each data element that you currently have (entity-relationship
diagram). The data don't necessarily have to be in a computer for you to consider the impact. Determine
which data elements work best together and how you will organize them in tables. Break your groups of data
into as small a unit as possible (normalization). Even when you say it's as small as it can get, go back again.
Avoid redundancy between tables. Decide what the key identifier will be for each record. See, you've done
all this and you haven't even touched the computer yet!

Give it your best shot in the beginning: it costs a lot of time, money, and frustration to go back and
make changes or corrections or to live with a poorly designed database.
There are three types of databases: hierarchical, network, and relational. Relational databases are
becoming the most popular of the three because they are easier to work worth, easier to change, and can
serve a wider range of needs throughout the organization.
4.4 Database Trends
Recent database trends include the growth of distributed databases and the emergence of object-
oriented and hypermedia databases.
• Distributed databases are usually found in very large corporations that require multiple sites to
have immediate, fast access to data. As the book points out, there are lots of disadvantages, so you
should be careful in determining if this is the right way for you to run your business.
• Object-Oriented and Hypermedia Databases: Many companies are steering away from strictly
text-based database systems. Data as objects can be pictures, groups of text, voice, audio, etc.
Object-oriented databases bring the various objects from many different sources and get them all
working together.
As we move away from strictly text-based information systems and incorporate video and sound,
graphics and text, the hypermedia database will become more common. The below given figure
helps explain the concept of a hypermedia database by showing how the various elements are
networked. The attraction to this type of database is that it allows the user to decide which path to
follow from one node to another.
Hypermedia database
• Multidimensional Data Analysis: As technology improves, so does our ability to manipulate

information maintained in databases. Have you ever played with a Rubik Cube - one of those cute
little multicolored puzzle boxes you can twist around and around to come up with various color
combinations? That's a close analogy to how multidimensional data analysis or on-line analytical

processing (OLAP) works (see the Figure given below). In theory, it's easy to change data around to
fit your needs.
Multidimensional data model.
• Data Warehouses: As organizations want and need more information about the company, the
products, and the customers, the concept of data warehousing has become very popular. Remember
those islands of information we keep talking about? Unfortunately, too many of them have
proliferated over the years, and now companies are trying to rein them in using data warehousing.
No data warehouses are not great big buildings with shelves and shelves of bits and bytes stored on
them. They are huge computer files that store old and new data about anything and everything a
company wants to maintain information on.
Since the data warehouse can be cumbersome, a company can break the information into smaller
groups called data marts. It's easier and cheaper to sort through smaller groups of data. It's still
useful to have a huge data warehouse, though, so that information is available to everyone who
wants or needs it. You can let the user determine how the data will be manipulated and used. Using a
data warehouse correctly can give management a tremendous amount of information that can be used
to trim costs, reduce inventory, put products in the right stores, etc.
4.5 Linking Databases to the Web
Even though Web browsers have been around for only a few years, they are far easier to use than
most of the query languages associated with the other programs on mainframe computer systems. That's why
many companies are starting to link their databases to a Web-like browser. They are finding out that it's
easier to provide their "road warriors" with Web-like browsers attached to the computer at the main office.
Employees anywhere can have up-to-the-minute access to any information they need. It's also proving
cheaper to create browser applications that can more easily link information from disparate systems than to
try to combine all the systems.
There are many ways to manipulate databases so that an organization can save money and still have
useful information. With technological improvements, companies don't have to continually start from scratch
but can blend the old with the new when they want to update their systems.
4.6 Management Requirements

Key organizational elements in the database environment.
Nothing is ever as easy as it sounds. As the above figure shows, there is a lot more to a viable, useful
database than just its structure.
4.6.1 Data Administration
Ask any manager what his resources are and he's likely to list people, equipment, buildings, and
money. Very few managers will include information on the list, yet it can be more valuable than some of the
others. A data administration function, reporting to senior management, can help emphasize the importance
of this resource. This function can help define and structure the information requirements for the entire
organization to ensure it receives the attention it deserves
Data Administration is responsible for:
• Developing information policies

• Planning for data
• Overseeing logical database design
• Data dictionary development
• Monitoring the usage of data by techies and non-techies
No one part of the organization should feel it owns information to the exclusion of other departments
or people in the organization. A certain department may have the primary responsibility for updating and
maintaining the information, but that department still has to share it across the whole company. Well-written
information policies can outline the rules for using this important resource, including how it will be shared,
maintained, distributed, and updated.
4.6.2 Data planning
At the beginning we said that as many users as possible should be brought together to plan the
database. We believed it so much then that we'll say it again here. By excluding groups of users in the
planning stages, no matter how insignificant that group may seem a company courts trouble.

4.6.3 Database Technology, Management, and Users
Change isn't just something you experience by chance; in all likelihood, it will be required
throughout the corporate structure. You need to get the non-techies talking and working with the techies.
Users will take on more responsibility for accessing data on their own through query languages if they
understand the structure of the database. Users need to understand the role they play in treating information
as an important corporate resource. Not only will they require a user-friendly structure for the database, but
they will also need lots of training and hand holding up front. It will pay off in the long run.
Database administration functions can:
• Define and organize database structure and content.

• Develop security procedures to safeguard the database.
• Develop database documentation.
• Maintain the database management software.
As with any other resource, managers must administer data, plan their uses, and discover new
opportunities for the data to serve the organization through changing technologies.
4.7 The Database Environment
Now, we are having basic understanding about the databases and the requirements of the
management and the organisation. Let us continues by knowing the database environment which will give
you a clear idea about how it is performing.
Let us recall what we learned earlier in this chapter. Database is an organized collection of logically
related data. Information is data that was processed to increase the knowledge of the person who uses it.
Example, your credit card company is collecting data about your purchases (date, amount,
merchant). The monthly statement contains information about your account. The credit card company
maintains a database of related data such as your name and address, the merchant you bought the
merchandise from and the credit card transaction information.
Let me explain the advantages we are enjoying by having database environment by an example.
The (PVFC) is a manufacturer of high quality all wood furniture. The product line includes:
computer desks, entertainment centers, dinette set, book cases and wall units. The figure below illustrates
how the information systems were developed for each department to run their own applications, without an
overall database design for the entire company. Each file is designed to meet a specific application such as:
order entry, accounting and personnel.

To emphasize the redundancies of the application approach, let us review another example related to
banks.
Bank Example: Consider a new customer, Smith, opening a savings account. The personal data and the
account information are entered into the Savings file. At a later time, Joe opens a money market account with
the Money Market Department. Same information is entered. Finally, same information is entered again by
the Loan Department where Joe obtains a car loan. These files are shown below:
Savings File in the Savings Department
Account Depositor Deposit

SSN Address Phone
Number Name $amount
111-11- (215) 204-

S-100 Smith, Joe 100 Main St., Phila, PA 19100 $1.000
1111 1234
S-101 Doe, Jones 222-11-

1234
Money Market File in the MM Department
Account Depositor Deposit

SSN Address Phone
Number Name $amount
111-11- 100 Main St., Phila, PA (215)204-

MM-320 Smith, Joe $500.
1111 19100 1234
Loan File in the Loan Department:

Account Depositor Loan

SSN Address Phone
Number Name $amount
111-11- 100 Main St., Phila, PA (215)204-

LD-123 Smith, Joe $2500.
1111 19100 1234
By seeing the above example we may conclude the disadvantages of the file system as the
following:
• Duplication of Data (Customer and Inventory data is repeated in each application)

• Limited Data Sharing (One department can't access the files of other departments)
• Program-Data Dependence (Data definition is hard coded in each program. Thus a change in the data
characteristics requires a change in all programs using this data)
• Lengthy Development Time and maintenance (Because there are many duplicated programs to
process same data)
Now, try to answer to the following question.
How would you intuitively 'redesign' the PVFC and the bank file system?
Just observe the following database design where the above listed disadvantages of file system are
completely eliminated.
Compare this database design with the previous 'traditional' file processing bank example, and note
how the redundancies were removed and that the customer record has to be 'related' to the accounts of the
same customer.
4.7.1 How are these relational databases developed?
We begin by analyzing the user's requirements .In the process of the analysis we develop the data
model (conceptual schema) representing the data requirements. The conceptual schema is independent of the

database type used. Finally we convert the conceptual schema into a physical schema which is peculiar to
the database management we use
Program – Report Definition Program – Display Definition Program - Transaction

User View 1 User View 2 User View 3
(Report) (Screen Display) (Transactions)
Conceptual Schema
Physical Schema
Part of the conceptual schema for the PVFC example would actually look like this:

Note that what we have here is a list of attributes for each entity (only some of the entities are
represented here) along with a designation of primary keys (underlined) and foreign keys (dotted underlines)
and links. (Note that ORDER LINE used to be ORDERED PRODUCT and the two IDs really should be
considered as foreign keys for what we are doing now. But for now these are minor details.)
So -- how do we build the schema above?
As an example, consider the invoice below. It is the user's view of the invoice data. It is a piece of
paper representing one possible output or report from a software system.
The user thinks of it as one 'entity', and we might view it initially as a single entity. In the end,
however, in the database it is likely to be stored in multiples tables.
We would take this output and start to build a conceptual schema from it. Then we would build the physical
schema. The conceptual schema represents the overall logical structure of the database. It is contains all
entities and the list of attributes for these entities. The conceptual schema is used as the bases for
representing primary and foreign keys, and drawing links among the entities. The conceptual schema is also
later used in normalization -- in seeing the need for normalization and in carrying out the normalization
tasks.
Building the conceptual schema requires a careful analysis of ALL output requirements for a
system. This analysis CANNOT be carried out if you do not clearly understand the business parameters or
rules that govern the use of the system. You have to understand the problem domain, not just what is
needed. You need to know
• What is needed?
• What is possible?
• What is not possible (or at least not likely)?

UNIT I
Lesson 5 – Integration of Information
Learning Objectives
1. To know the importance of integration of data in business

2. To learn how ERP systems make business run better through integration of information
3. To understand the workgroup tools which will improve business integration
4. To know the important of data warehouses in integrating data
5. To understand the role of internet in integrating data of different types of systems.
5.1 Introduction
Coordinating the many aspects of business requires a wide variety of information from many
sources. Perhaps you need to make a decision about how to market a new product. You would retrieve
a variety of customer data from the sales database. You would use reports from the production team
and a collection of graphs created from the initial marketing surveys. You could use a spreadsheet to
analyze this information along with various marketing strategies. Along the way, you would probably
use accounting data to create graphs to display costs and projected profits for the various cases.
Finally, you would use a word processor to create a formal report for your supervisors that describes
the choices and your analysis. The report would contain your writing along with the graphs,
spreadsheet tables, and some of the data.
Consider a sample business decision where you are working as a manager at a department
store. Three reports are produced by the central computer: .the daily sales report, returned
merchandise log and a commission report. At the end of each week, you create a report that evaluates
the profitability of each department. You also maintain a line graph that shows the net sales number
for each week. At the end of the month you write several pages of comments about the trends and the
monthly activities: The report includes copies of the data and your graphs. It is sent to upper
management
To see how the use of computer is changing, consider how this report might have been
produced by managers at different points in time. In the 1970s, the central computer track sales and
printed all the three reports. At the end of the week, the manager computed the net sales by hand and
drew the graph on graph paper. A secretary would then type the report on a typewriter and staple the
graph at the end of the document.
In the 1980s, personal computers with spreadsheets and word processors were introduced to
the business world. At this point, the manager entered the numbers from the reports into a spreadsheet
by hand. The spreadsheet did the calculations and created the graphs with only a few commands. A
word processor was used to type the report. The spreadsheet printouts and the graphs were stapled in
the final report.
In the 1990s, the process was simpler. First a database management system held the sales
data. Spreadsheet commands retrieved exactly the data needed, performed the calculations, and
produced the graphs. The report was still typed on a word processor; however, the spreadsheets and
graphs were automatically copied into the word processor document This process was facilitated by
software suites that consist of software packages designed to exchange data.
Managers can buy integrated software to instantly produce all of the reports and graphs, and
then click on items to obtain more detailed information. Think about what happens if some of the
original data is changed. Just before you send the report to management, someone calls and says that
the sales figures for half the items in the housewares department are wrong. In the 1970s example, the
manager had to re compute all of the totals, redraw the graphs; and rewrite the report. The 1980s
manager had to change the numbers in the spreadsheet, rewrite sections of the report, and print the
new graphs. The 1990s manager would simply tell the word processor to reprint the report. The word
processor would automatically tell the spreadsheet to get the new data, update the graphs, and transfer
the results to the final copy. With a truly integrated system, the data would always be correct, and
reports and graphs would always have current values.

Integrating data is only the first step. Modern companies are increasingly based on teams,
where individual employees from various departments are assigned to projects. Each person may be
assigned separate tasks, but the work must be assembled into a final project evaluated and approved
by the entire team. You need tools that track the progress of the group, let multiple people work on the
same documents at the same time, and track the history of changes.
A difficulty that arises when you are trying to integrate information is the diversity in
hardware and software. For example, each software package uses its own format to store data files. As
a result, there are more than 50 different formats for word-processing documents. The problem
multiplies rapidly when you consider that most of these formats change with each software revision.
To integrate these different types of information, you need software that can read many different file
types, or the software needs to use a common format
One trend in software is the adoption of enterprise systems that are designed to hold data in a
central database. These systems provide consistent data across the company. A trend in personal
productivity software is toward packages that work together by sharing data through links. When the
underlying data changes, the software automatically pick up the new data and update the document.
The concept is similar to a spreadsheet formula that refers to other cells. The key difference is that
you can refer to data in different programs; such as transferring data from a spreadsheet into a word
processor. With a network, the data can be located in different departments throughout the business.
5.2 Integration in Business
For a business to be successful, it needs to integrate information from all aspects of the orga-
nization. Modern management techniques of just-in-time production and mass customization require a
high degree of internal integration, as well as strong links to suppliers and customers
As you know, most companies are split into functional departments, with varying degrees of
independence. However, there are always pressures and decisions that affect the entire organization.
For instance, changes in products or manufacturing schedules clearly affect the marketing department.
Because these changes will probably alter the cash flows of the company, the accounting and finance
departments also need to be aware of the changes
In the 1960s and 1970s, computer systems were built for individual departments and areas
within the company. In many companies, these systems became islands. They were focused on one
task and did not share data with each other. For instance, the accounting department collected the
basic transaction data and produced the necessary accounting reports.
Anyone in the company who wanted to use this data relied on paper printouts of the standard
reports. When spreadsheets arrived in the 1980s, the basic accounting numbers were often re-keyed
into spreadsheets in other departments. Besides wasting employee time in retyping numbers that were
already stored on a computer, this practice caused more errors from mistyping the data. Additionally,
consider that when the accounting department changes the numbers, some users of the data might not
get the updated versions, and people would attempt to make decisions on outdated data.
Computer use in most companies began with transaction-processing systems. Because
transaction systems are structured and there is considerable experience at this level, it is a logical
place to begin. However, it is also tempting to treat each transaction separately: (1) Payroll services
can be purchased from a specialized data-processing company, so the data will be handled separately
from the other corporate data. (2) A sales order processing system might be constructed independently
of the inventory control system. (3) Process control systems to handle manufacturing tend to be
isolated because the data (e.g., robotic control signals) are different from the data used in the rest of
the company. (4) Similarly, the corporate accounting system is often developed as a stand-alone
product. Journal entries are created by copying data in reports produced by other systems. Although
each of these transaction systems offers management advantages to their respective departments, it is
difficult for managers to use data from other departments. Also, independent systems make it difficult
for executives to share data and evaluate interrelationships between the departments.
The amount of data integration needed in a company often depends on the management
structure of the firm. Some firms are highly decentralized, so that each business unit makes its own
decisions and functions independently of the others. Typically in these situations, only accounting

data (profit/loss) are integrated and reported to upper management.

On the other hand, some organizations are much more integrated. In your economics courses
you were shown the difference between vertically and horizontally integrated firms. Consider a
vertically integrated firm such as an oil company that functions at different levels of production
(including oil exploration, drilling, transportation, storage, and retail sales). Although an oil
exploration team may not need access to daily fuel sales in Mumbai, they do need to forecast future
demand for oil. Likewise, the retail sales division does not need to know the daily costs associated
with drilling for oil, yet they might need to track deliveries and communicate with the corporate
office.
Consider a horizontally integrated firm such as Wal-Mart with retail stores in many different
cities. It achieves lower costs by combining the buying power of all its stores. By coordinating sales,
warehouses, and distribution, Wal-Mart can negotiate better prices with manufacturers. Additionally,
Wal-Mart reduces operating costs by standardizing management practices (and information systems)
across all the stores. By integrating information from all stores, it is easier for Wal-Mart to forecast
customer demands. Also, by networking the store information systems, managers who experience
higher sales of certain products can request shipments from stores that are not selling the item as
rapidly
Manufacturing firms can gain additional benefits from integrating data. Benefits like just-in-
time inventory, total quality management, and mass customization can only exist with the tight
integration of data. The National Bicycle Industrial Company of Japan illustrates how integrated data
is used to provide customized products to mass markets.
5.3 Role of Enterprise Resource Planning (ERP)
Enterprise resource planning (ERP) is the current state-of-the-art in-integrated information

in business systems. The systems incorporate data from financial accounting, logistics, and human
resource management. The field is dominated by large, expensive software packages from companies
such as SAP, Peoplesoft, Oracle, Lawson, and J. D. Edwards. The systems use databases, processes,
and rules to provide up-to-the-minute data on the major financial issues in a firm. One of the key
points of ERP systems is that they run on top of a DBMS, hence, all of the data is centralized and
accessible via DBMS queries and reports.
ERP systems handle all of the financial accounting systems. They also emphasize purchasing,
human resource management, and investment management. The systems are tailored for specific
businesses and can focus on areas such as manufacturing, research and development, and retail sales
One of the primary strengths of the ERP systems is that they were designed to handle data for
large companies operating in an international environment. In the late 1990s, many companies chose
to install commercial ERP systems, instead of trying to modify their existing systems to handle the
year 2000 problem
5.3.1 International Environment
Several features are important to firms operating in an international environment. First, all
menus and reports should be available in several languages, so clerks and managers can use the
language they prefer. Second, the system should handle currency conversion automatically, so
managers can view reports in any currency. Similarly, conversions should be capable of being fixed at
a point in time, so that when items are transferred they can be valued at the exchange rate in effect at
that time, even if the rate changes later.
A more complex feature for the international environment is the ability to produce reports
following the rules of individual nations. For example, a company with subsidiaries in many nations
would need to produce reports that follow the rules (e.g., depreciation) for each specific nation, and
then produce consolidated reports following the rules of the home nation
A third complicating factor arises from taxes. In addition to the rates, the rules and procedures
vary by nation. The rules are particularly important for payroll and benefit applications. A good
enterprise application automatically incorporates the rules for each nation and state

5.3.2 Financial Systems
The accounting system is a core feature of an ERP. Eventually, all transactions must be
recorded in the general ledger accounts. The accounts fulfill the standards required by each nation.
They are used to create the standard accounting reports. The systems provide flexibility by enabling
managers to create their own sub-accounts and sub-ledgers, which are used to create reports on
additional topics. An important feature of the accounting system is that standard accounting reports
can be generated at any time for any section of the company. The ERP system automatically uses the
most up-to-date data.
In addition to standard financial accounting, the systems manage assets and provide common
treasury functions such as cash management. The systems also provide basic audit trails and other
accounting controls. To make them easier to use, most ERP systems provide enterprise (or executive)
information system (EIS) capabilities. Managers can examine data at virtually any level of detail.
From summary values, they can drill down to more detail.
5.3.3 Logistics
Logistics consists of the operations required to purchase materials, deliver them to the ware-
houses and factories, and sell and distribute products. It incorporates traditional MRP analysis, quality
control, accounts payable, and accounts receivable
In today's manufacturing companies, logistics is an important component of just-in-time
inventory and demand-driven production. Using an integrated system, the marketing department gets
up-to-the-minute data on customer demands. Marketers can cooperate with designers and engineers to
develop new products. The specifications can be transferred to the production machines and raw
material orders can be generated for vendors. Purchasing and payments can be tracked and generated
over EDI networks-including the Internet. As orders are generated and inventory levels change, the
accounting data is automatically updated-providing instant analysis of profitability.
For service-oriented companies, logistics involves service management tasks. The ERP
systems can track customers, identify repeat customers, monitor service contracts, help salespeople
with call management, and handle automatic billing and accounts receivable issues
5.3.4 Human Resource Systems
As we all know, payroll is a complicated function, particularly in a multinational environment

involving different rules and currencies. Even in a single state, the issues of benefits, state and federal
rules, and legal issues arising from child support make handling payroll a complex task.
Today's HRM departments handle such additional tasks as recruitment, training, travel, and
organizational planning. Each step must be documented and requires a variety of federal and state
reports. In addition to these basic tasks, most of the major ERP systems enable HRM departments to
offer Web access to basic data. For example, employees can use the Web to check on their taxes,
change their withholding status, and sign up for benefit plans and training sessions.
5.3.5 Integration
Integration is probably the most important feature of the ERP systems. All the data is stored
in a central database; hence, data is entered only one time (but into a double-entry accounting system).
All reports are generated from the base data. Custom queries and reports can be generated through the
DBMS.
Consider a simple example. A manufacturing plant takes an item from inventory. The system
instantly adjusts the inventory quantity on hand. It also updates the financial value of the inventory
holdings on the general ledger and any sub-ledgers that utilize that figure. New orders can be
triggered automatically with the orders and payments sent through common EDI mechanisms. All of
the changes are made automatically. When managers request reports, the new data is automatically
incorporated and displayed using current currency conversions

The key point you have to remember is that all of the transactions and accounts are integrated.
Managers can request reports by using any combination of data at any time-and each report will use
the most up-to-date information
Most of the major ERP systems also utilize distributed hardware and software. Hence, the
database can be split into many pieces stored in different locations. As changes occur in one location,
they are automatically distributed across the network to the other locations. The company can add a
subsidiary with its own processing support. Yet, all of the new data is readily accessible to managers
throughout the company.
When a factory uses an inventory item, the system reduces the current inventory count. It also
changes the inventory valuation in the general ledger. The item usage might trigger a purchase
through the EDI system, which must also be recorded-along with the accounts payable change. Since
the databases are shared across the organization, all changes are automatically included when new
reports are generated
Kindly remember that all of the modules are integrated. So manufacturing schedules
developed in the production module automatically provide data to the payroll system and personnel
systems. Then the financial data (e.g., wages) is linked back to the general ledger, which provides
updated data for all financial reports
One important catch with an ERP system is that it requires changes to the way the company
operates. In many cases, these changes can be good-for example, it forces everyone to follow the
standard accounting procedures. In other cases, the ERP is too inflexible and interferes with the way
the company operates. Managers have to carefully evaluate the tradeoffs of integration and flexibility
5.4 Customer Relationship Management
Although customers are important to all businesses, the Internet and wireless applications add
new dimensions to managing customer relationships. One problem is the expanding number of
customer contact points, from sales representatives, to call centers, to websites, and wireless
connections. Customers expect merchants as suppliers to remember actions and decisions that were
made earlier regardless of the method of contact. Consequently, companies need integrated systems
that instantly provide all details of customer contacts. The new technologies also provide innovative
methods to keep in touch with customers and identify their specific needs to sell additional products
and services. Several software tools have been developed to improve customer relationship
management (CRM).
5.4.1 Multiple Contact Points
One of the greatest challenges facing a company today is the multiple sources of contact
points with customers. Most of the original systems designed to handle these interactions are separate.
Salespeople often keep their own records; Internet support systems may not be totally connected to
the sales fulfillment centers; faxes are rarely integrated into the online customer files. But customers
assume that when they talk to one person, that person has records of all the prior interactions.
At first glance, it appears that it would be straightforward to build an integrated application to
hold all customer interaction data. Of course, it would be a lot of data and would take time to build
the application. But the real challenge lies in getting everyone to enter all of the data. Consider the
situation of a salesperson who has invested time and collected substantial data on product preferences
and customer work environments. That information gives an advantage to the salesperson. Why
would the salesperson be willing to share it?
Customers with multiple divisions and many different product tracks also add complications
to CRM. The system has to be able to track transactions, questions, and issues by a variety of factors
(date, product, company, person, and so on). The system also needs a sophisticated search routine so
users can find exactly the pieces of data required
5.4.2 Feedback, Individual Needs, and Cross Selling

The main purpose of CRM systems is to provide individual attention to each customer to im-
prove sales. By tracking prior purchases, you understand the status of your customers. By providing
new channels of communication, you improve the ability of customers to provide feedback to
comment on products and services and to make suggestions for improvements. By identifying patterns
in purchases, you can develop new ideas for cross selling, If a group of customers tends to purchase
several products, you can search the CRM database to find customers with only part of the solution,
and have your salespeople demonstrate the advantages of the entire suite--using the other customers
as examples and references.
The flip side to CRM is that collecting and coordinating substantial data about the customer
can lead to privacy problems. As long as the data is secured and used internally, few problems arise.
But firms still need to be sensitive to customer wishes about unsolicited contacts. In fact, customer
privacy requests need to be part of the CRM system. The issues are more complex when the selling
firm has multiple divisions, and each one wants to push new products to existing customers. The
marketing staff needs to use the CRM system to coordinate and monitor all contacts.
Wireless applications provide even more options for CRM. Your salespeople can stay in
constant contact with the corporate database. They can retrieve current shipping status, or detailed
customer information during a sales call. They can forward questions or comments, which can be
analyzed and answered immediately
5.5 Workgroup Integration
Cooperation and teamwork have always been important in managing a company. Today, as
firms remove layers of middle management and as they focus on teamwork, integration and sharing
become crucial. Making decisions requires input from different people. Problems that arise are solved
by creating a team of workers-often from different disciplines
Picture yourself as a manager in a modem corporation. In addition to your day-to-day tasks,

you will be asked to serve on various teams to solve problems. You could be working with three or
four different groups simultaneously. How do you organize your work? How do you remember the
status of each project? How do you keep in touch with the team members? How do you keep track of
documents, comments, and revisions for each team? How do you know which team members are
falling behind and need more help? Now assume that the team members are scattered across different
locations. You cannot afford to schedule meetings every week. How do you keep the project moving
and make sure that all important ideas are incorporated in the final decision?
Software tools known as groupware have been created to help answer these questions and
make it easier for teams to work together. Groupware tools are designed to make it easy for several
people to work on a document at the same time, regardless of where each one is located. Lotus (IBM)
Notes and Microsoft Exchange are two tools based on e-mail that are often used as a foundation for
groupware applications. Essentially all shared data is stored in a giant e-mail database with some links
between related messages. Probably their strongest feature is the shared calendars that enable team
members to schedule meetings.
On the other hand, Microsoft has slowly been integrating many of the features into the
standard Office products (Word, Excel, PowerPoint). Microsoft Office XP did not change much in the
way that components worked; however, it did add several Internet tools to facilitate teamwork. Most
of the tools use standard Web protocols, so authorized users can use them even when they are
traveling. A special website has to be created to support the tools. Generally, this website should be
run on a company server, using standard security precautions. If you want higher security, you can run
the website as a secure site and encrypt the data transmissions. Small companies might consider
obtaining
5.5.1 Announcements and Lists
It is always amazing to learn how difficult it is to contact everyone on a team. People work on
many projects, at different times, in different locations. Consequently, even simple information can be
hard to share. Basic announcements are useful for these situations. Announcements are short

messages that are displayed to everyone-generally they are displayed prominently on the first page.
Lists can be created to display timetables for tasks, contact names, or any other category needed by
the group
The power of sharing lists through a website is that members of the team can see the lists at
any time. As authorized members make changes, everyone has access to the current data.
Additionally, the lists can be organized and searched by various categories, such as deadline, project
sponsor, or participant. Some standard lists exist in SharePoint, such as contacts and schedules.
Additional lists can be created at any time
5.5.2 Web Discussion and Surveys
Most students are familiar with Web-based discussion groups. SharePoint implements a basic
news-type service where participants can post questions or reply to comments made by other
members. Discussion administrators establish topics and can specify the roles of the other team
members, such as the ability to read or reply to comments. Discussion groups are useful on team
projects to discuss issues that arise.
The strength of the computer-assisted discussion is that everyone has access to the
comments, and the entire record is available if questions arise later. It also makes it easy to search
for specific problems. Discussions can be created on any topic. Common business uses include
overall comments on scheduling, sharing research information, and discussing problems that answer.
Surveys are useful for some business applications. In particular, they come in handy when
designing new systems. Generally they are used to obtain a quick perspective on individual opinions.
Paper surveys are a pain. Web-based surveys are easy to change, easy to fill out, and can instantly
report the data. You simply write the questions by selecting a format, entering the question, and
identifying the possible responses. When you post the survey to the Share Point site, the other mem-
bers of the team enter their selections. The results are immediately available. One advantage of the
system is that the entire process is done through Web forms. Note that the surveys are not available
to people unless they are registered in the group, so the technique does not work as well for public
surveys. On the other hand, more sophisticated tools can be purchased from other companies to
handle public surveys
5.5.3 Document Libraries
Until recently, most organizations shared files through shared directories on LANs or via e-
mail. Document libraries are simply Web-based folders that hold a related collection of documents-
such as all work on a particular project. The files are accessed across the Web, so they are accessible
to team members anywhere in the world. Additionally, the group leader can establish a template so
that all documents have the same look.
Once the site is set up, accessing the documents is easy-through the familiar File and Open
commands. Generally, you will create a link to the directory in "My Network Places" so you can find
the documents with one click. In a team environment, it is important to store your files in a document
library-instead of on your personal machine. That way, everyone in the group can read and contribute
to the work. Once the documents are stored in the shared library, some other powerful tools and
options can be used to coordinate the team, as described in the next sections.
Some versions of SharePoint can also handle version control. Version control consists of
maintaining earlier copies of a document that can be retrieved if needed. Additionally, version control
systems support check in and check out of documents, so that only one person can edit a document at
a time-minimizing the problem of needing to determine which change to keep. It also tracks who
made the changes and which team member is currently using the document. If you want complete
version control including the ability to automatically track changes, you will also need Visual Source
Safe, Microsoft's version control software.
5.5.4 Tracking Changes
Have you ever tried to write a document with two or three people? What happens when you

have a draft that is passed around to the others for comment? If it is a paper document, odds are that
each person starts marking changes on the document. Hopefully, each person uses a different color
pen and records some notes about why the changes were made. Modern electronic documents can
support the same type of editing electronically. Simply turn on electronic protection to enable the
document to track changes. Then as each person deletes or adds items, the changes are marked in
color. In the end, the person in charge of the document can unprotect the document and quickly go
through and accept or reject the changes to produce the final version. Figure 7.12 shows a sample
Word document with marked changes. It also shows how discussion comments can be added to the
document.
5.5.5 Subscriptions
Individual team members can set a subscription to entire folders or to individual documents.
Whenever a document is changed, the user is notified bye-mail. This feature has many uses for teams.
Consider the situation when you need to wait for a team member to finish a section before adding
your analysis. You could pester the team member with phone calls until he or she finishes; you could
hope that the team member e-mails you directly; or now you can simply let the server notify you as
soon as the file is updated. You can control how quickly the notification is sent; for example,
immediately for critical items, or daily for minor items. Subscriptions also tie into the next topic of
approvals and work flow control
5.5.6 Approval Routing and Work Flow Control
Group members rarely work independently. Most businesses establish some type of control
procedures. For example, your manager probably wants to review recommendations that you make;
purchasing managers are responsible for approving the purchase of major items; and important
documents have to be approved by the legal department. Projects tend to have discrete steps.
Sometimes the steps are as simple as obtaining an approval and comments from someone before
proceeding. Other times, complex business rules have to be followed to ensure the proper input and
controls are followed. These more sophisticated systems are known as work flow procedures
SharePoint makes it relatively easy to support routing documents and obtaining approvals.
You can attach a routing list to any document when you send it. The system delivers it to the first
person on the list. When done, he or she clicks a button and it is sent to the next person on the routing
list. Along the way, each person can add comments. These comments are stored in a discussion board
associated with the document. Additionally, the document can record changes and indicate who made
them. Hence, everyone can see the final document, what changes were made, and comments on why
the changes are important
More complicated work flow rules can be created with lists and some minor programming.
For example, a list can be created to describe the state of a document (draft, approved, final). Then
various conditions and triggers can be applied to specify conditions for each state and how the
document must be handled. For instance, two specific people must approve a document before it can
leave the draft state and move to the next steps. Or, a document must have three completed and
approved figures before it is considered to be complete. These rules require some effort to set up, but
once established, the system enforces the basic procedures of the business. Additionally, team
members can check on the progress of a project to see what steps remain, or identify which team
member is holding up a particular document.
5.6 Integrating with Legacy Systems
In many ways, the design and implementation of an information system is easier if you are
starting a new company or rebuilding one completely. With older (legacy) systems, existing data and
software might be incomplete and inconsistent. Valuable information and processes are embedded in
these systems; we cannot just throw them away and start over. Yet, it can be more difficult to retrieve
data from these systems and integrate it into new management systems
As business operations and management change, information systems need to be updated.

Management emphasis on teamwork is a significant change in the last few years. The improved
integration features of current software fit nicely with the changes in management to-ward teamwork
and integration across the enterprise. The problem is that few companies have the opportunity or the
money to completely redesign their information system to take advantage of these new features. As a
result, they need to use the data stored in their legacy systems. This data must be made accessible to
decision makers so it can be analyzed. To meet this need, some companies are creating a data
warehouse. A data warehouse is a single consolidation point for enterprise data from diverse
production systems. The data is typically stored in one large file server or a central computer
Many older online transaction processing (OLTP) systems store data in their own files,
without using a database management system. Although transaction systems produce standard reports,
managers often need to use the base data to perform additional analyses or in depth searches. Before
the widespread use of networks, managers often entered data from each report into their own
spreadsheets. Installing a network offers the ability to share data across the company. However, the
data must be stored in a format that is accessible to the managers. Larger database management
systems have specific tools and data storage methods to create data warehouses. Some companies also
create specific data marts that are basically copies of a small portion of the data warehouse designed
to feed a specific application. For instance, a financial data mart might be used by the accounting and
finance department just to monitor investments and bank accounts.
5.6.1 Building a Data Warehouse
The goal of a data warehouse is to hold all of the data needed by managers to make decisions.
Hence, the first step is to determine the data needs and models that managers use. The next step is to
identify the data sources that are available in-the company. This step can be difficult when the data is
stored in hundreds of different files, scattered across many different machines. It requires analyzing
company data sources in depth and documenting the business processes
Once the data needs and data sources have been identified, the data must be transformed and
integrated so that it can be searched and analyzed efficiently by the decision makers. In many cases,
the data warehouse is created as a static copy of the original data. Instead of building a link to the
original data files, it is easier to copy the data into new files. Special programs are run periodically to
update the data warehouse from the original data.
The next step is to document the data warehouse. Metadata is used to describe the source data,
identify the transformation and integration steps, and define the way the data warehouse is organized.
This step is crucial to help decision makers understand what data elements are available. It also
enables managers to find new data
Once the data warehouse has been defined, programs are written to transfer the data from the
legacy systems into the data warehouse. In some cases, managerial applications are created and
distributed. Applications can be written for decisions that occur on a regular basis. For instance,
finance decisions involving cash flow must be made every month or every week, and rely on standard
data. On the other hand, applications for ad hoc decisions will have to be created as they are needed.
5.6.2 Limitations of Data Ware House
A data warehouse represents a subset of the total data in the company. In most cases, it is a
static copy, not a dynamic link. Consequently, managers might not always have the most current data.
Similarly, data not transferred to the data warehouse will still be difficult to find and use. Data
warehouses are not always stored in relational database management systems. Instead, they are
collections of files and the data items are extracted and transmitted to managers' personal computers.
This type of system is .relatively easy to use; managers do not have to learn data access commands
(SQL or QBE). However, it is less flexible than using a database management system. Decision
makers will be unable to get additional data or to compare the data in some previously unexpected
way. The success of a data warehouse depends on how well the manager's needs have been
anticipated.
5.7 The Internet: Integration of Different Systems

It is difficult to build systems that integrate data. Hundreds of problems arise even if all of the
data lies within one company. The data is often pulled from different software packages running on
diverse hardware. The data formats are rarely the same, so data has to be converted. For example, one
system might use five-digit ZIP codes and a second might use nine digits. And dates are always a pain
because every system stores and displays them differently.
Displaying data and documents developed by different people on many types of computers is
exactly why Tim Bernets-Lee developed the early Web browser. He was working with physicists at
CERN and needed a method to help them share their data and research. The Web has come a long
way since that time, but the emphasis on creating standards to share data is still paramount.
Consequently, e-commerce is currently the hotbed for developments in integrating data.
EDI standards were originally developed to help companies share data with their partners,
suppliers, and customers. But its progress stalled as firms found it difficult to build easy-to-use EDI
systems that worked well with their internal systems and procedures. Initial EDI technologies also
required that all transaction data be predefined and fit within the framework of the standards. Several
firms began to realize that they needed a more flexible method of sharing data.
Technologists are working on systems to make it easier for companies to share data. One
useful standard is the extensible markup language (XMU. XML is a method to define and transfer
data between companies and applications. As shown in Figure 7.16, all of the data within an XML
document is in a specified format and tagged so that a computer program can quickly read the file and
identify the data and its purpose. Several companies, including IBM and Microsoft, are developing
technologies to use XML to make it easier to share data across companies.
At its foundation, all data is transferred similarly to this example, but XML is considerably
more powerful and more complex. Among other things, it supports a version of a style sheet to define
and share the structure of the document (the tags). Several industry groups have created XML
definitions for sharing data specific to their industry. These data templates make it easier for you to
share data, and easier for programmers to develop applications that automatically send and receive the
data. The main advantage of XML is that each message contains a description of the purpose of the
data as well as the data itself. Hence, the receiving program can evaluate and understand what was
sent
Standards are a critical process in sharing data. Hundreds of standards exist to enable
computers to connect at a physical, electrical, and data level. New standards are being developed
every day. Developing standards is not easy, and many arguments arise during the process. Each
vendor wants specific protocols and methods in the standard, and many of them would give one
vender an advantage over the competitors.
To a manager, the entire issue of computer standards can be confusing. The most basic issue
is that it would be wonderful if everyone could immediately agree on a single standard for every
definition. That way we could buy hardware and software from anyone and know that it would work
together on any of our computers. This utopia will probably never exist because of changes in
technology and the constant competition among manufacturers to gain an advantage. In reality, we are
forced to guess which technology will succeed and which standard will eventually dominate the
others. Choosing incorrectly can result in ownership of orphaned products that are no longer
supported. You also end up changing hardware, software, and data more often, which results in
expensive and disruptive conversions
Unfortunately, there is no simple rule that will tell you how to choose a direction or standard.
Some companies avoid the issue by avoiding new technology and waiting until it is clear which
technology will win. Both strategies can cause problems: In particular it means that you will always
be a follower instead of a leader. While there are advantages to being a follower, it makes it difficult
to use technology to gain an advantage over your competition.
5.8 Summary
Working together and sharing data are crucial in today’s companies. MIS can help teams
work better with tools designed to integrate data across an organisation. Managers need to know how
to use a variety of tools, from data sharing over networks, to dynamic linking, to groupware products.

Enterprise resource planning systems are commercial systems designed to collect and share
data across the company. Most of them concentrate on transaction processing data with a special
focus on accounting systems. However, the consistent data provides a solid foundation for additional
analysis.
Workgroup software like lotus notes combines many features to facilitate work on group
projects. It supports communication, document sharing, integration of data types and tracking
individual changes.
Integration often requires combining data from different locations. Networks enable you to
dynamically link the work done by different people. However, if everyone in a company uses
different software, it becomes difficult to combine the information because each software package
stores data in a unique format. As a result, companies generally create standards for how the data will
be stored and accessed. Although these standards are often necessary, several problems can arise
when some users have special needs or the standard needs to be changed.
Points to Ponder
The Abstraction-Synthesis
Methodology (ASM):
• The information needs of the functions to be supported
with the technology are determined using organizational
control systems modeling (OCSM) framework
(Kampfner, 1987)
• The logical (See Figure 3), performance, and user
interface requirements of the information system that will
support these functions are then determined. Any
information system that satisfies these requirements is in
principle capable of providing the necessary support.
• We follow a synthetic approach to design in which the
alternatives are synthesized and then evaluated as to
their ability to meet all the requirements of the
information system. One alternative that meets all the
information system requirements is selected for
implementation.

Function Support:
Three characteristics of an Electronic Document
Management System that are fundamental for the
effective support of organizational function:
1) The classification scheme, or indexing scheme, used to
organize the document images must be consistent with
the information needs of the function.
2) A broadly-based user interface.
3) A close integration of the informational and non-
informational processes, realizing the functions.

CIS Project: Information Needs

Analysis:
• We determine the information needs of a subset of the
functions of the CIS Department’s Office. These
functions need the information that may be made
available with document imaging technology.
• A Function Description Management Tool will be used
to support the CIS Department Office’s functions. This
tool will be used in storing description of functions in the
database. Also with the help of this tool, the addition,
deletion, and updating of functions will be easily
accomplished and utilized (See Sample Function in
Table 1)
• With the use of the ASM we can determine structural
features and dynamics of the information system
processing. (See Figures 1 and 2)

Design of the Electronic Document

Management System
• The classification scheme was developed from the
criteria specified in Table 1, in a manner consistent with
the functions supported by the information system.
• A prototype system has been designed for document-
imaging technology. The image Server Software uses an
SQL server and a scanner. The design includes a LAN
with a Windows NT server, and three display
workstations. (See Figure 4).
• The integration of document imaging technology into the
functions means that the technology works in harmony
with the non-informational processes. (See Figure 5).

UNIT I
Lesson 6 – Information Systems, Organizations, and Business Processes
Learning Objectives
• To understand the relationship between Information Systems and Organisation

• To study the influence of Information systems on Organisations
• To learn how Information Systems changed the business processes
6.1 The Relationship between Organizations and Information Systems
This lesson will describe how organizations and information systems work together, or sometimes
against each other. The idea of course is to keep them in sync, but that's not always possible. We'll
look at the nature of organizations and how they relate to Information Systems.
The Two-Way Relationship
This figure shows the complexity of the relationship between organizations and information
technology. Installing a new system or changing the old one involves much more than simply
plunking down new terminals on everyone's desk. The greatest influence, as the lesson points out,
could simply be sheer luck!
What Is an Organization?
Now, let us have a brief understanding about Organisation. An organisation is very similar to the
Information System described in the earlier chapters. Both require inputs and some sort of processing,
both have outputs, and both then depend on feedback for successful completion of the loop.
Information Systems use data as their main ingredient. Organizations rely on people. However, the
similarities are remarkable. They are both a structured method of turning raw products (data/people)
into useful entities (information/producers).
Think of some of the organizations you've been involved in. Didn't each of them have a structure,
even if it wasn't readily apparent? Perhaps the organization seemed chaotic or didn't seem to have any
real purpose. Maybe that was due to poor input, broken-down processing, or unclear output. It could
very well be that feedback was ignored or missing altogether.

6.2 Salient Features of Organizations
This section gives you a perspective on how organizations are constructed and compares their
common and uncommon features.
Why Organizations Are So Much Alike: Common Features
The class you're enrolled is an organization of sorts, isn't it? Think about it. Look at the following list
describing the structural characteristics of an organization:
• Clear Division of Labour

• Hierarchy
• Explicit rules and procedures
• Impartial judgments
• Technical Qualifications for Positions
• Maximum Organisational Efficiency
Why Organizations Are So Different: Unique Features
Would you consider the same organizational structure for a softball team as you would for a theatre
production group? While there would be some similarities, the two groups would probably have some
major differences. An automobile dealership would have some similarities to a department store (both
sell products) and yet they would have major structural differences. Organizations that enter into
collaborative partnerships tend to seek out companies with similar structures. It is much easier for the
employees to work together if they aren't required to learn a whole different work structure on top of
learning new tasks.

This table shows some common organizational structures. Think about your own experiences, in your
workplace or your daily life, and try to list some organizations that fit into each category. They're all
around you. Remember, just as organizations affect you in many different ways, so too do you affect
the organizations.
Organizations and Environments
Some organizations are able to respond faster and better than others. Look back 10 years: The
minivan didn't exist. But because of changing consumer requirements and tastes, the minivan is now
one of the most popular and best selling vehicles on the road. If the organizations called automobile
manufacturers hadn't responded to the changing environment, they wouldn't have been able to
capitalize on new car sales. Notice that Chrysler responded faster than the others and gained
tremendous market share in the meantime. Its organization is almost as big as those of Ford and GM.
Yet those two weren't able to respond as rapidly to environmental changes and hence lost potential
sales. The same is applicable here with Reliance Infocomm.
For instance, contrast a real estate company with an insurance company. The real estate company is
constantly looking for new customers (buyers and sellers) and new products (houses or commercial
properties) to sell. It may choose to stay small or to go with a nationwide conglomerate. The
environmental factors that are likely to influence it are the state of the national economy or the nature
of the local economy. Many external factors are out of its control. The employees of the company
must respond quickly to potential customers or they simply won't make any money. This type of
organization must be creative in the way it generates business and in the systems it uses.
On the other hand, the insurance company has relatively stable customers. People sign up with the
insurer and pay their premiums on a regular basis. While customers may come and go, turnover is
fairly low. Because most state governments require people to carry insurance, the company and its
agents have a stable stream of income from premiums. While the parent company may suffer large
losses from a sudden influx of customer claims, the small agency is not as heavily influenced by
environmental factors. It doesn't have to devise ingenious ways of using or generating data, and its
systems needs are very ordinary.
Both businesses are small and entrepreneurial. But they must respond to employees, customers, and
potential customers in very different ways. Each has different business processes it must use to meet
the goal of staying in business.
Other Differences among Organizations
The external forces on an organization are tremendous. You're living in a time when these forces are
causing many organizations-public, private, and governmental-to reevaluate and alter their
organizations because of the Internet. Some organizations are responding faster and easier than others.
Why? Much of the cause can be attributed to the structure of the organization.

If the structure and culture of the organization promotes new ideas, new products, and new methods,
the organization can deal with environmental changes faster than a more staid organizational
structure. Some companies are simply so big that they can't change their structure as fast as
technology demands.
Business Processes
What would happen if you walked into work one day to find the management telling employees they
could do anything, anything at all, they wanted to do that day. If Jimmy from Production decided he
wanted to work in Sales and Marketing, he could. If Sandya, who normally works in Accounting,
wanted to spend the day in Shipping, she could do that too. No one would have to follow any rules, or
any set procedures. They could accomplish the work any way they chose.
Mary decides she doesn't want to use FedEx to ship out products that day even though the company
has a contract that saves lots of money. She decides to use an alternate shipping service which will
cost the company more and slow down the shipment significantly. She doesn't see a need to tell
Accounting about the change.
Jimmy decides not to use the same old packing materials when he's preparing glass bowls for
movement across the country. He determines that it is faster if he just plops the bowls into a box,
closes the lid, and sends it down the line. Unfortunately, his co-worker Tim (who doesn't know
anything about Jimmy's decision) is responsible for answering customer complaints.
Brinto in Accounting decides that he needs a pay raise to help pay for his upcoming vacation.
Normally he would be required to get his supervisor's approval to change any pay record, but since
there aren't any established procedures he can just go ahead and enter the new salary data in the
system. While he's at it, he gives ten of his best friends pay raises also. While Brinto's friends may
like the idea, the rest of the employees in the company are pretty upset.
You can imagine from this scenario how quickly chaos would reign without established business
processes. Processes that deliver the best product for the lowest cost in the most efficient manner are
imperative to success. The way a business organizes its workflows, the methods it uses to accomplish
tasks, and the way it coordinates its activities among employees, customers, and suppliers determines
its business processes. Organizations, from the smallest one- or two-person group to the largest you
can imagine, must have orderly processes that all divisions can understand. No part of the
organization can work in isolation from any other part.
Some processes may have contributed to the organization's success and now outgrown their
usefulness. Information Systems can help an organization recognize processes that need to be
changed. An Information System could be used to automate some of those processes or determine that
they are no longer needed. And a successful organization will use an Information System to determine
which processes are working well.
The key to using Information Systems to analyze, change, automate, or delete processes is that the
organization must determine the appropriateness of the recommendations. In other words, if the
system says a process should be changed but it truly doesn't make sense to change it, then don't make
the change. The system supplies recommendations; humans still have the ultimate decision-making
responsibility.
6.3 How Organizations Affect Information Systems
Change is the only constant in the relationship between information systems and organizations. You
need to consider:

• How have organizations actually used information systems?

• How has the organizational role of information systems changed?
• Who operates information systems?
• Why do organizations adopt information systems in the first place?
Decisions about the Role of Information Systems
Years ago Information Systems consisted of a huge mainframe computer with a few terminals
connected to it. You had to schedule a specific time to use the computer if your company had one at
all. All data were kept on one machine, and in some respects the data were available to whoever could
access them.
When personal computers were introduced in the early 1980s, it became the norm for most people to
have individual computing islands on their desks. The computers weren't connected, so if you wanted
to exchange data or information, you had to somehow get the data from your desk to the other
person's desk. It wasn't easy.
Now it seems we've come full circle: we've combined the storage and data processing on a central
machine with personal computing available on desktops. The data are available to anyone who can
use them or has authorized access through a network with links literally all over the world.
The changes that have taken place in computing have affected the business environment in a big way.
Over 40% of the equipment investment in the last decade has been for computing equipment.
Organizations are finding more efficient ways to accomplish tasks via networking, either through
internal networks or by connecting to external networks. Technology has caused many changes in the
way businesses connect to customers and suppliers. We'll examine many of these changes throughout
this course.
Information Technology Services
Many new jobs have been created because of technology. Information Systems departments,
previously a tiny group of people usually assigned to the financial group, have moved into the
mainstream of most companies. Programmers have taken on more important positions within
organizations. They must understand not only the technical side of computing, but also the business
processes within the company so they can adapt the technology to the needs of the business. System
analysts serve as the bridge between the techies and the non-techies. Heading this group of people are
the information systems managers. Their importance to businesses has grown as the emphasis on
technology's role within organizations has grown. Just as most organizations have a Chief Financial
Officer, the position of Chief Information Officer has been created to handle the problems and
opportunities businesses face in today's technologically driven environment.
Perhaps the most important role of all is the end user. The responsibility for successful integration of
Information Systems has extended past the "techies" and become part of everyone's job. No one is
isolated from the effects of computers and technology any more.
Why Organizations Build Information Systems

The systems development process
Organizations incorporate technology for many reasons. The most obvious reason should be to save
money through improved work processes and reduced manpower requirements, and to beat the
competition. Unfortunately, some organizations adopt the latest technology just because the
competition has it. The company may not fully understand all the implications of incorporating the
new technology into its core business and fail dismally. Some companies use Information Systems to
help them create a better mousetrap. That is, they use the advantages of Information Systems to create
new services, build better products more efficiently, or invent new products altogether.
But there is more to an organization that what happens internally. Much of what drives change in an
organization, good or bad, are external forces (environmental factors). Over the last decade or so,
government entities and the public at large have demanded more and more information. Consumers
want more information about the products or services companies produce, and the government
requires more and more paperwork.
The very nature of a business may change in such a way that it is possible to carry on only by
incorporating an Information System (institutional factors). For instance, all the major airlines offer
programs that give customers incentives for flying with their company instead of the competition. The
airlines couldn't afford to offer these programs if it weren't for Information Systems. Imagine the
number of workers it would take, not to mention the time and paper, to track every customer earning
and using the incentives.
6.4 How Information Systems Affect Organizations
We will now discuss two major types of theories about how Information Systems affect organizations:
economic theories and behavioral theories.
Economic Theories
It's sometimes cheaper to hire a computer than to hire a person. We may not like the idea that
machines can replace human beings, but when you think about it, they have been doing this for
thousands of years (microeconomic model).
To better illustrate this concept, let's take a look at how a company can find it cheaper to use an
Information System to develop and disseminate a Human Resources policy regarding dress codes for
employees. The HR assistant may write the first draft of the policy and give it to the HR director on
paper. The director will review it and make changes. The assistant then must incorporate the changes
and reprint the document. Wait! If there is an Information System, the assistant can submit the draft to

the director electronically and the director can make changes to the electronic version of the file and
return it to the assistant. Already we've saved part of a tree!
Once the policy is set, it has to be sent to each employee. We could do that through the old method of
printing hundreds of copies. Or we could send the policy to each person electronically (email).
Everyone would have a personal copy stored on computer. There no need to print it out on paper since
it will be stored electronically and can be accessed whenever it is convenient. By acknowledging
receipt of the policy via email, the HR department knows everyone has received it.
One way that technology in general, and information systems in particular, save companies a lot of
money is in the reduced number of managers needed to oversee larger numbers of workers. The
technological changes support agency theory, which says that owners hire agents to do work but then
must have others supervise the agents to be sure they work in the companyÕs interest. Technology
allows a manager to supervise more employees, thus reducing agency cost.
Behavioral Theories
Technology doesn't automatically transform organizations. There is no magic wand companies can
wave and have all their problems solved just because they install the latest information system.
Let's say your company decides to develop a new method of shipping hammers. You would need to
draw people from the Production department, the Shipping department, the Packaging department,
and the Accounting department to help develop the new procedures. Without an Information System,
you would need to have a clerical worker available to record and send out all the information to
everyone before and after the meetings. You would have to set up a time and place for team members
to meet. Scheduling everyone's time is often a nightmare! Because of the political nature of
organizations and people, which we'll talk about later in this chapter, most of those assigned to this
team would probably have to be middle managers.
If your company had the proper Information System, much of the hassle and expense of this scenario
could be eliminated. By using technology, most of the collaboration and communication throughout
the organization, top to bottom, side to side, could be accomplished quicker and cheaper.
One of the biggest benefits would be the fact that the decision-making process can be pushed to lower
levels, and management can check progress electronically. Perhaps the managers wouldn't be as afraid
to delegate responsibility because they can keep an eye on the committee throughout the process.
Everyone in the entire organization could have access to the work of the committee. The behavioral
theory of the integration of Information Systems in an organization says that the political structure of
an organization changes through access to information. The common status symbol in an organization
used to be the corner office. Now the status symbol is how much information a person has access to.
When a company introduces change to the organizational structure because of a new or revamped
information system, political changes will occur at the same time. Some people will gain and some
will lose. Naturally people will resist changes that affect them negatively. It's human nature.
The Internet and Organizations
The example used earlier of posting personnel policies to the company Intranet is but one small
example of how businesses are using network technologies to reduce costs and enhance their business
processes. Business-to- business commerce is growing at a tremendous pace because of the cost
savings the Internet allows. The Internet provides an open platform technology which allows
transaction processing between businesses at much cheaper cost plus an easy-to-use interface. The
innovative ways organizations are using the Internet, Intranets, and Extranets to improve their
business processes are simply amazing.

UNIT I
Lesson 7 – Management of Information Systems and Information Technology
Learning Objectives
• To understand the role of Information Technology in Organisation

• To know about the Inter-Organisational Systems
• To study the impact of Information Technology in Business Transformation
7.1 Introduction
As a manager you will be in a position to assess how information technology can be used to
support business activities. Traditionally data processing applications have supported “back office”
operations, such as transaction processing. However the introduction of information systems which
electronically linked purchasing personnel with order-entry system proved that businesses could use
information technology to gain a competitive advantage. This lesson shows how businesses can use
information technology for competitive advantage and how inter-organisational systems have
transformed the competitive market place.
No wonder we agree that we are living in an Information Age which is influencing major
decisions happening in the Industry Level and very small decision in your personal lives also. The
advancement of Technology has given enormous benefits to us by enabling all our practices more
competent because of the availability of all kinds of information at a cheaper cost.
Let us see the basic components of Information Technology and its way of working first. The
understanding of computer technology is the base really to acquire a better understanding about the
Information Systems.
7.2 Computers and Computer Processing
The classification of computers depends on computing capacity and data processing speed. Let's
review each of the classifications.
• Mainframes: These are the huge computers you see in a big room where people in white
coats mill around. Until the mid-1970s they were the only computers available. With the
invention of the mini-computer and later the personal computer, many people said
mainframes were too big, too expensive, and not needed anymore. The Internet and the
advent of computer networks literally saved the mainframe from oblivion. Mainframes have
the necessary power and speed to process millions of transactions from the Internet and
networks and have the storage capacity needed for all the data captured and processed by
larger Information Systems. America Online, the largest Internet Service Provider in the
world, uses many mainframes connected together to process all the transactions across its
network and to provide Internet access to the 17 million users who subscribe to the AOL
service.
• Minicomputers: Mini-computers have less power and capacity than a mainframe but more
than a personal computer. They were responsible for bringing computing capacity to a level
that smaller companies could afford. Now they are used in smaller networks that don't require
the power and speed of mainframes. While they are still useful in many cases, they are
sometimes replaced by more powerful workstation and personal computers that are connected
to emulate the power of a mini-computer.
• Workstation computers: The workstation computer can be easily confused with a personal
computer (PC) because it is configured much the same way. However, this computer has
more computing capacity in its CPU than a typical personal computer. Scientists and

engineers are the main users of workstations, although people who process graphics (or
pictures) find a workstation necessary, since the processors can handle the huge amounts of
data associated with graphic files.
• Personal computers: While this class of computer used to be called a microcomputer, and
sometimes still is, that label gives a false impression of what the machine can do. The prices
of PCs have dropped drastically in the last two years, while computing capacity and power
have continued to increase. Many small businesses find it cheaper and easier to connect
multiple PCs to form a small network than to purchase more expensive equipment. It's
estimated that over 60% of the U.S. population has a personal computer in the home.
• Supercomputers: Because computing capacity and power were increasing so fast and so
much with mainframes and other types of computers, many people didn't see a need for
supercomputers. As with the mainframes, the increasing use of networks, with their insatiable
appetite for speed and storage, are allowing supercomputers to make a comeback. There are
still situations in which the power of supercomputers is necessary: The National Weather
Service uses a supercomputer to store models of weather patterns to help predict storms or
sunny days.
A few years ago a computer called "Big Blue," manufactured by IBM, played a series of
chess games against Garry Kasparov, the greatest chess player in human history. The interesting part
of this match lies in the fact that the computer used a technology called parallel processing. That is,
it had thousands of processors working together to calculate each move it would make and the
countermove Kasparov would make. Kasparov, on the other hand, was only using one processor - his
brain - to calculate all the moves by both sides. Kasparov actually beat the computer for a few rounds
but ultimately lost the match. It's fascinating to think that the computer, able to process millions and
millions of instructions per second, had to use all of its strengths and massive parallel processing to
outwit a person using one single processor. Think about it!
Computer Networks and Client/Server Computing
Client/server computing
With the increasing popularity of networks, you need to understand the server/client structure.
Think of an octopus, with the body representing the server and the tentacles representing the clients.
At the heart of every network is a server. It can be a mainframe, mini-computer, workstation, or a
souped-up personal computer. It's where some of the data, applications software, and other
instructions that network users need in order to communicate with and process transactions on the
network are stored. The client computer is the node on the network that users need in order to access

and process transactions and data through the network. The following figure shows some different
types of client/server computing.
Types of client/server computing
There are many different configurations for networks, and the text discusses the difference
between distributed processing and centralized processing. Which one works best, you ask? It
depends on the requirements, needs, and wants of the people who own and use the network. Managers
should analyze their situation and determine the proper configuration to meet their needs.
Network Computers and Total Cost of Ownership
The cost issue is becoming more important to businesses and companies as computer technology and
networks grow. Depending on the configuration of the network, a company can save or lose many
dollars. What's most important to remember is that the Total Cost of Ownership (TCO) should
extend past the hard dollars spent on hardware and software. The cost should incorporate such as
items as employee training, their ability to perform necessary functions given the network
configuration, and lost productivity when the network is down. The TCO should also include the
amount of money spent on communications wiring (telephone wires, fiber optic cable, etc) and
security and access issues.
7.3 Information Technology Trends
The speed and computing capacity of technology continues to advance at dizzying speeds and in ways
we can hardly imagine. Star Trek is no longer a vision for the 24th century but for next week.
Interactive Multimedia
One trend highly touted by the experts is that of the "information appliance." Do we need to
have a separate device for watching television, another one for listening to music, a different one
called a telephone, and yet a whole separate device for computing? Some people say we can do all of
that with one central appliance with a variety of input and output devices.

If you watch the mergers taking place in the corporate world between the telephone
companies and cable TV companies, you can start to understand another major change that may be in
store for us. The companies are working toward a convergence of the "entertainment outlets" we
know as television and the Internet. Why can't we download a movie off the Internet whenever we're
ready to watch it instead of having to follow a TV channel's set schedule? This idea may be a reality
in a few years.
The music industry is struggling with the issue of music downloaded from Web sites. How do
the musicians protect their copyrighted work while making the music more accessible to the public?
How do the music publishing companies protect their business from disintermediation, the process of
eliminating the middleman from transactions?
Smart Cards and Microminiaturization
Take a credit card out of your wallet and look at the magnetic strip on the back. The strip may seem
too small to hold much data. You might be surprised to learn that through microminiaturization,
virtually all of your personal information, from health records to school records to credit records, can
be stored on that small area with room to spare. Some states are now including vital medical
information on the back of driver's licenses which can be accessed by paramedics if you're ever in an
accident and need medical attention. The technology has already saved lives.
Social Interfaces
Bill Gates, Microsoft Corporation, has a vision of the future of computing. Speaking to a reporter for
Business Week magazine, May 17, 1999, he says: "Desktop PCs have been incredibly successful.
Most businesses have them, and 50% of homes do. And for most people, the PC will remain their key
computing tool, but it will also work alongside a lot of other cool devices. That's why we've expanded
our vision to giving people the power to do what they want, where and when they want, on any
device. That means on PCs, handheld PCs, phones, or smart TVs such as WebTV."
When asked what he saw on the horizon that will dramatically change people's lives, he replied: "I'm
optimistic about what the industry can achieve, but the word ÔdramaticÕ will mean different things to
different customers. If you're a large enterprise customer, being able to connect your employees with
on-demand videoconferencing for collaboration would be dramatic. If you are head of IT for a large
corporation and can deploy software, do updates, and change users on a companywide network of
PCs, and never visit a desktop, ever - that's dramatic. If you have a PC at home and use the Web to
buy products, such as a car, a TV, or a dishwasher, and if you can use your PC to track the warranties,
find the nearest repair center, and have your PC store remind you of all that information - that would
be dramatic."
So where are we going with all this technology? Computers that are easier to use and incorporated
into our everyday lives are in the near future. Improved technologies for business computing are being
introduced each day. Faster and smaller information appliances are coming to a store near you. When
it comes to the future of computing, your imagination is the only thing holding us back.
7.3 Role of Information Technologies on the Emergence of New Organizational Forms
During the last years, a consensus is emerging that to survive in the competitive turbulence
that is engulfing a growing number of industries, firms will need to pinpoint innovative practices
rapidly, to communicate them to their suppliers and to stimulate further innovation. In order to be
competitive, companies are forced to adopt less hierarchical and more flexible structures, and to
define strategies able to combine reduced costs, high quality, flexibility and a quick answer to

customer requirements. Nowadays, there are very few companies with enough resources to form its
value chain on their own.
Therefore, some changes are taking place within individual companies and in their relations
with other organizations, creating new structures in which relationships between
customers and suppliers are suffering considerable changes. One of these changes is concerned with
the formation of networks in which there is a division of labour that allows each company to exploit
their distinctive advantages, and be more competitive globally.
In a network model, a set of juridically independent companies establish cooperative long
term links in order to achieve a higher level of competitiveness. The enterprises that belong to a
network have not all the elements needed for manufacturing a product or providing a service under
their absolute control. Therefore, the success of this kind of structures is conditioned by the
coordination degree obtained along the realization of inter-organizational activities, which requires an
efficient communication system among the partners. The Information Technology (IT) represents a
supportive element that facilitates the transfer of information across organizational boundaries. In this
paper we analyze the inclusion of the Interorganizational Information Systems (IOS) concept within
the network model and discuss the role IT plays in enabling organizational transformation towards
emergent forms of organization.
In order to attain relatively low costs in the last two decades the enterprises followed
strategies of backward-forward integration, based on the improvement of the effects of the experience
curve and the scale economies. We consider that this internal growth may be inadequate to face the
new situations appearing in the nineties and, no doubt, those that will appear in the next century. The
individual enterprise has less capability for foreseeing the consequences of the different business
decisions; however, the need for competing in a more and more complex context requires the
adoption of quick decisions, which facilitate the flexibility of the enterprise. New technologies, fast
changing markets and global competitiveness are revolutionizing relationships both within and
between organizations. Thus, the new environment requires from the enterprises a strategy able to
agglutinate reduced costs, high quality, flexibility, and a quick response to the needs of the customer.
Nowadays, the enterprises have to compete in a more and more turbulent scene, which obliges
them to adopt less hierarchical and more flexible structures. During the last years, a major
transformation in the strategy of many enterprises has been observed with a tendency to
disintegration. This is accompanied by a need for increasing the quality of the products or services
offered, which requires more interdependency among the different corporate units. As a consequence
of it, several transformations both inside the enterprises and in the relationships between them are
taking place, which establishes new structures through which the relationships among competitors,
customers and suppliers are changing substantially. One of these changes is the cooperation
established among different enterprises, which allows them to develop their competitive capability.
Companies are forming strategic alliances because there is an increasing acknowledgement that
organizations operate in a relational context of environmental connectedness and that organizational
survival and performance depend upon connections with other organizations.
The co-operation among enterprises allows their flexibility and their innovative capacity to be
increased. Current products are based on so many critical technologies that most of the enterprises
cannot keep constantly updated in all of them.
The Network Structure
The concept of the network’s form of organization has been particularly popular with
management writers for its potential to build the flexible organization with the ability to meet the
challenges of a changing and global environment. Despite both the abundant available literature and
the existence of a certain consensus on some aspects, there is still too much ambiguity in the concepts
used in this area. Taking into account the formation of networks, which is an interesting field of recent
development with strong repercussions on the inter-organizational relationships, it is necessary to
clear the existing terminological confusions in order to formulate its theory and to improve its
implementation.
Starting from the definition, a network is a specific kind of relationship joining a particular
group of people, objects, or events. Two factors needed for constituting a network can be obtained

from this definition; first, a network is formed by a group of elements; second, these elements
establish specific relationships among them. We must show that the establishment of a co-operative
network is not a purpose itself but «it must be a dynamic structure that allows consolidating the
competitive position of its members».
By means of a network structure, the competitive position of the enterprises can be reinforced
as these concentrate on what they do best, and on what maintains their success in the market. In this
way, other enterprises make the activities left, in which they have distinctive competences too. The
enterprises outsource those activities that are ballast and bureaucratize them.
The enterprises that belong to a network have not all the elements needed for manufacturing a
product or providing a service under their absolute control. Within the networks, the involved
elements belong to independent enterprises and are placed along the value system of a product or
service.
All this drives to an organizational structure in which the enterprises generate more value in
those areas where they have specific competencies. The success of these emergent organizational
forms seems to be based, on a great extent, on an effective co-ordination by means of the use of
advanced information systems, which are based on the Information Technologies (IT). There is an
increasing interest in the relationship between the emerging organizational ways and the function of
the IT/IS insofar as the progresses in each field have influenced the others.
Information Technology On the Emergence of Networks
At the moment, the most spectacular and potentially powerful uses of the information systems
technology go beyond the individual borders of the enterprises. In fact, the most important function of
IT in the nineties is the better management of the interdependencies among the enterprises.
Information Technology has to be the most powerful instrument to reduce the co-ordination costs».
While the traditional uses of IT tried to facilitate the internal processes of the enterprises, the
Interorganizational Information Systems (IOS) are addressed towards the efficiency of a group of
enterprises.
Most of the studies about IOS have focused on the incidence of IT on the flows of
information among the organizations, its capability of reducing the transaction costs, and its potential
to achieve competitive advantages. Many authors have verified that:
• IT influences the nature, punctuality and detail level of the information shared by enterprises
• IT reduces the transaction costs, while it provides a better management of the risks
• IT reduces the co-ordination costs
In order to benefit from the advantages of IT, the enterprises have to keep in mind that IT
cannot be isolated from its organizational context». We do not agree with the existence of causation
between the implementation of IT and the organizational changes in the enterprise driving to an
increase in the competitiveness of the enterprises. On the contrary the technological and
organizational implementations are both sides of the same issue, since they depend on and determine
each other». We think that, although IT might have the above mentioned positive effects on the
organizations, the will and capabilities of the directors of the company are needed in order to make the
most of those advantages.
In order to make the most of the whole potential of the IOS, it will be required that the
managing directors get involved with the project, since they have a wider and more strategic view of
the company. In this way, a system coherent with the objectives of the company would be
implemented. This system would allow taking even more profit from IT, what would have positive
repercussions on the enterprise and would facilitate the achievement of its objectives. The active
participation of the Management Board in the planning of the IOS brings a problem related to the fact
that IT is a relatively new resource that did not exist when most of the current managers were trained.
Therefore, they usually do not feel comfortable with these new technologies.
As a proof of this, we will consider an example. McKesson was a dealer company of chemical
products. This company knew that its success was linked to that of its customers, which were small

stores, so it established a close relationship with them. By means of an appropriate use of Information
Technologies, it helped its customers to maximize their profits, since it gave them useful information
for competing with the big pharmaceutical chains, which were getting a greater market share. The
McKesson Corporation directors’ idea was so successful that many other enterprises of the sector
tried to imitate it, but they made a terrible mistake. They thought that the network created by
McKesson was just a computerized system with terminals connected in other enterprises.
The secret of the success of this company were not the computer links; information
technology did not create the network. The network’s success was due to the fact that the directors of
McKesson were aware of both the relationships along the added value chain and the need to
strengthen as much as possible every link within the chain, so cooperative behaviors could be
established in order to provide the share of information and the quick response to the changes of the
demand.
Another example, widely mentioned in the literature on Information Systems, is the one of the
American Hospital Supply Company whose success has shown up the need to consider the network
established not only as a mere system of electronic data exchange, but also as a better implementation
of the technology found within a context of changes in the commercial relationships between the
enterprise and its main customers.
They state that the implementation of this kind of technologies per se does not bring any
competitive advantages; on the contrary, they must be accompanied by some particular elements,
generally intangible, which facilitate the operation of the organization by means of a better
distribution of the information and the experience. They also reflect a collaborative attitude among the
enterprises.
A positive consequence of the revolution of communication and Information Technologies is
that there are more available options for designing the labour now, because the technology can be
used to increase the capacities of the workforce, and the information can be transferred to those places
were the labour is carried out. Workers do not need to be located according to parameters of time and
space to co-ordinate any more.
We consider that technology, although it is not the ground for the emergence of a new and
innovative way of organizing the enterprises, plays an important role in its operation. Technology
allows doing things in a different way, which provides the directors some organizational possibilities
that would be unthinkable without its implementation. Thus, using a mathematical expression, we can
state that Information Technologies are necessary but they are not enough to achieve greater business
competitiveness.
The Role of IOS within the Network Structure
The enterprises involved in an alliance must decide whether to use the manual management of
all the exchanged data, or to complement that management with the interconnection of their respective
computer applications. This interconnection may bring, however, compatibility problems in the
integration of the data from the different enterprises, since those applications would have possibly
been designed without taking into account any requirement of integration among enterprises. The
establishment of co-operation networks implies the need for wider communication in the
organizational field, as well as the requirement of capability to integrate the information systems from
different enterprises.
The enterprises inside a network cannot operate properly if they have not the possibility to
communicate quickly, accurately, and over long distances. Within a network, it does not make any
sense to restrict the application of modern computer technologies to the individual borders of each
enterprise. The Management Board of the enterprises in the network must, on the contrary, consider
the possibilities of co-ordinating the processing of data outside the limits of their own organizations
by means of an IOS.
The application of the IT which provides the electronic integration among the shareholders of
an industry may make easier the outsourcing of activities, as well as be a basic part of the proper
operation of the reticular structures. An IOS may play an important role in the coordination of
interdependent activities, which would be carried out by distant organizational units. Thus, the

enterprises can reduce their dependency on strategies of backward-forward integration in order to

ensure the control over the production process.
The concept of network emphasizes the interdependency among enterprises, which is
provoked by the presence and the sharing of the following key attributes: objectives, experience,
labour, taking of decisions, responsibility, trust, and acknowledgement or reward. The enterprises
within a network will adopt a common objective, namely to provide a quicker and better service to the
final customer. With this aim in view, independent organizations will have to establish close
interrelationships, in which Information Technologies have a vital role to play. In this way, the aim of
optimizing the flow of profits along the supply chain could be achieved too. IOSs are, basically, new
means to facilitate the relationships among organizations; they are, therefore, a strategic instrument.
However, an IOS allows to obtain operative advantages too, such as
• Reducing paper-work and manual operations;

• Reducing the stock levels;
• Accelerating the product and material flow;
• Standardizing of procedures;
• Accelerating the flow of information about changes on the demand;
• Reducing telecommunication costs.
The IT is a basic support that facilitates the co-ordination of different enterprises through EDI
systems, shared databases, e-mail, videoconferences, which will allow them to work together. They
will be able to share information on the markets, on the needs for materials, on stock levels,
production schedules, and delivery programs. A key factor in an efficient exchange of information
within a network is the computer connection of its members. The computer links accelerate the
transference of information, since it provides the automatic transmission of data between physically
distant computers. These links can be used as a strategic instrument to increase the competitiveness of
the enterprise, binding it electronically with its customers and suppliers through inter-organizational
systems. The electronic connection facilitates the approaching of the linked enterprises, which means
that the companies may provide the customers direct access to the internal databases, as well as just-
in-time stock control.
Changes in the Business Environment and their Effect on Organizational Design
The powerful worldwide changes have altered the environment of business. These changes in
the business environment and climate are classified into political, social, economical and
technological categories.
Environmental, organizational, and technological factors are creating a highly competitive
business environment where customers are the focal point. Further, environmental, organizational,
and technological factors can change quickly, sometimes in an unpredictable manner.
Therefore, companies need to react often and quickly to both the problems and the
opportunities resulting from this new business environment. This dramatic change is due to a set of
business pressures or drivers. They maintain that in order to succeed (or even to survive) in this
dynamic world, companies must not rely only on traditional actions such as lowering cost, but also
encourage innovative activities by empowering employees.
Organizations are composed of five major components: IT, organizational structure and
corporate culture, management and business processes, organization’s strategy, and individuals and
roles. These components are in stable condition, called equilibrium, as long as no significant changes
occur in the environment or in any of the components. However, as soon as a significant change
occurs, the system becomes unstable and it is necessary to adjust some or all of the internal
components since all are interrelated.
IT and Organizational Design

An important and fast growing technological innovation during this century is computer-
based information systems. Computer-based information systems (CBIS or only IS) provide an

opportunity for businesses to improve their efficiency and effectiveness, and even to gain a
competitive advantage. IT is also a catalyst of fundamental changes in the structure, operations and
management of organizations. Most businesses in the industrial world could not compete, and many
could not even survive without computers and software. Now IT is an integral part of the products and
services delivered to customers.
Competition leads to environmental uncertainty and increases both the need for and the rate of
innovation adoption. By adopting IS, businesses will be able to compete in three ways:
(1) IS can change the industry structure and, in doing so, alter the rules of competition;
(2) IS can also create competitive advantage by offering business new ways to outperform
their rivals; and
(3) IS spawns new businesses, often from within existing operations of the business.
IT-enabled Organizational Transformation

There is a growing body of conceptual papers and case studies on IT-enabled organizational
transformation in the information systems literature. Most of the studies suggest that the use of IT
without concomitant organizational changes is unlikely to yield significant gains in terms of
organizational performance.
Four R’s of Business Transformation

Business Transformation can be defined as “The orchestrated redesign of the genetic architecture of
the corporation, achieved simultaneously – although at different speed – along the four dimensions of
reframing, restructuring, revitalization and renewal.” By this definition a biological model has been
developed that we call the Four
R’s of transformation: Reframing, Restructuring, Revitalization, and Renewal.
The meaning of Four R’s:
Reframing is the shifting of a company’s conception of what it is and what it can achieve with new
visions and a new resolve
Restructuring is a girding of corporate loins, getting it to achieve a competitive level of performance
by dealing with the body of corporation and competitiveness. The need to be lean and fit is the
primary consideration.
Revitalization is about igniting growth by linking the corporate body to the environment. Renewal
deals with the people side of transformation, and with the spirit of the company. It is about investing
individuals with new skills and new purposes, thus allowing the company to regenerate itself.
Five Levels of IT-induced Reconfiguration

The above figure is a schematic representation of these five levels along two basic dimensions – the
degree of business transformation and the range of potential benefits from IT. Organizations thereby
proceed to higher levels of transformation as the demands of competition and value creation for
customer increases. The first two levels are evolutionary, requiring relatively incremental changes in
the existing organizational processes. In contrast, the other three levels are conceptualized as
revolutionary, requiring fundamental changes in the nature of business processes. These five levels
are explained as following
• Level 1: Localized Exploitation (Automation), which is concerned with the exploitation of IT

within business functions.
• Level 2: Internal Integration, a logical extension of the first in the sense that IT capabilities
are exploited in all the possible activities within the business process. Two types of
integration are critical here: technical integration and the organizational integration by using
common IT platform to integrate the organization’s business processes to enhance efficiency
and effectiveness.

services and
• Level 5: Business Scope Redefinition concerned with the underlying principle of a
corporation, pertaining to the possibilities of enlarging the business mission and scope
(through related products and services) as well as shifting the business (through substitution
of traditional capabilities with IT-enabled skills).
Summary
We note that the future organizations would be facing a shortage and a redundancy of
information. To solve the problems of "information-glut" arising from the evermore affordable
information and communication technologies that provide for evermore high-capacity, fast, long-
distance transmission, organizations would need to introduce methods for "selective dispersion of
information" to their various parts. Work tasks would be grouped in organizational units created
around a common program for information processing. Improvements in telecommunications will
make it easier to control [which will be primarily a matter of information exchange] organizational
units dispersed over different parts of the world. Advances in telecommunications [such as
videophone], coupled with diminishing costs, would result in increased distance-communication.
Indirect communication would be preferred for well-structured information for routinized,
"preprogrammed" decision processes.
The design of the organizational structure should take into account and take advantage of the
information and information- processing supports which could be designed, and in the not- distant
future will be inexpensive. The technology itself is neutral, but it can greatly increase humanity's woe
or welfare, depending on how well it is used. What is missing is the full recognition of the strong
interactions between this technology and organization design, and the consequent need to take a
systems approach to the joint design of organizations and their information support systems.

This decade has brought companies around the world a tremendous increase in competitive
pressures. In order to survive, organizations need to be highly flexible and responsive to the rapid
twists and turns of markets and technologies. Management theorists rushed to offer alternative
organizational models. The transformation in organizational structure may be facilitated by advances
in Information Technology. But, IT is not effective if it is not accompanied by an innovation in the
human and organizational parts simultaneously. The connection of information systems of distant
organizations requires organizational changes in order to improve a wider share of data among them.
In our opinion, a co-operative network is the perfect frame in which a major improvement of the
potential advantages of an IOS can be obtained.
The network pursues to integrate the distinctive capabilities of different enterprises in it, by
means of collaborative agreements which involve closer relationships among them. The network
structure allows an enterprise to specialize and to reduce costs in those activities from the value chain
that are basic for its competitive advantage, leaving its partners to realize the activities particular to
their respective specialty areas.

UNIT I
Lesson 8 - Information Systems and Strategy
Learning Objectives
• To review the understanding about Business Strategy and its components

• To understand the role of Information Systems in Strategy Formulation and Implementation
• To learn how to use Information Systems for gaining competitive advantage
8.1 What is strategy?
Let us start this session with this question to review what you have known about Business Strategy.
According to Mintzberg, the word strategy is used in several ways. Some of them are given below:
• A plan
• A ploy
• A pattern of behaviour
• A position in respect to others
• A perspective
Two important differences:
• Deliberate strategy: preconceived, thought about, explicit, monitored and controlled: a

plan
• Emergent strategy: a consistent pattern of behaviour; ‘what we are used to doing’
Definition of business strategy:
Strategy is the determination of the basic long-term goals and objectives of an enterprise and
the adoption of courses of action and the allocation of resources necessary for achieving these goals.
Note the importance of: Objectives, Course of action, and Allocation of resources
8.2 The Strategy Development Process
While developing any strategy, the following questions will come into picture and we must try to
answer them by formulating and implementing the strategy.
• Where are we:

- Internal situation
- External environment
• Where do we want to go, what do we want to achieve – what are our objectives
• How do we get there, recognising
• That there are forces which restrict us (e.g the state of the economy; strength of the
competition)
• Our imagination and will may help us to overcome these restrictions
• The future business situation can never be completely known
• As a business grows it usually becomes more complex
The Process in Outline

• Defining the mission statement - what business are we in and what is our vision for it?
• The internal audit
- where are we
- and where are we heading?
• The external audit – what environment are we operating in?
• What are our objectives
– what should we do to satisfy are stakeholders?
• The strategic options
- what might we do?
• The strategic choices
what do we decide to do?
• The action plan
• Implementation:
- Take the action
- Review progress and evaluate
- Change, as necessary
Managing the Process
• There is an existing busy business, with established habits

• Usually, no-one is waiting for planning to begin
• The first time – provisional planning may be useful
- Doing the best we can with the information available
- Talking to people to find out what they think needs attention in the company
• It must be driven by the top man
• It must be seen as relevant and helpful – not a collection of theoretical requirements
• It must involve those who are expected to make it work
- somebody else’s plan: lacks interest; easily generates resentment
• It must generate regular feedback, to show that it is working and worthwhile: not a once-a
–year exercise
• It must allow scope for imagination
• It must allow scope for change when circumstances alter
• Note: plans are uncongenial to much human behaviour:
Remember: Mintzberg: The (management) job breeds adaptive information-manipulators who prefer
the live, concrete situation. The manager works in an environment of stimulus-response and he
develops in his work a clear preference for live action.
8.3 Information Systems and Business Strategy
Did you ever play a game you intentionally wanted to lose before you started? Usually the
answer to this question is no. It's very unusual for businesses to want to fail. Companies have every
intention of beating their competition by using Strategic Information Systems.
Keep in mind that when we discuss the strategic role of information systems in this section
we aren't talking about strategic level information systems. Information Systems can play a strategic
role in an organization if they are used effectively throughout the company. Two ways to do that are
through beating the competition and adding value to products or services. Let us assume a company
called WorldWide manufacturing candy bars in the name of Cybernuts. We can use Information
Systems throughout WorldWide Candy to make Cybernuts better than any other candy bar, at perhaps
a lower price, and to make consumption of the Cybernuts candy bar the "hip" thing to do.
Business-Level Strategy and the Value Chain Model

You have to decide where you want your business to fit in the marketplace. Are you going to:
• Become the low-cost producer

• Differentiate your product or service
• Change the scope of competition
Leveraging Technology in the Value Chain
Be better than the competition. That's the mantra of most companies that are serious about
winning the game. Areas of the organization most affected by leveraging technology are producing
the product, getting it to the stores, and making the customer happy. Think of all the activities that go
into getting the Cybernuts candy bar made, from procuring raw materials to actual production. Then
consider how the candy bar gets from the factory to the store shelves. And what about all those
product commercials? These are primary activities. Just as important are support activities: Human
Resources, Accounting, Finance. These functions support the primary functions of Production,
Shipping, and Sales and Marketing. The value chain model below will help an organization focus on
these activities and determine which are critical to its success.

Information System Products and Services
Cybernuts uses a better recipe for making chocolate than any other candy bar. We know that
from our Knowledge Worker System. Sales and Marketing can use that information in promotional
campaigns to advertise how much better and different Cybernuts is than any candy bar the consumer
has ever eaten. Since our Office Automation System is top-notch and the clerical workers processed
the patent information so quickly, our competition can't duplicate the recipe. They are left with the
old, icky, bad-tasting chocolate everyone is tired of. Product differentiation allows you to bury the
competition by making your product and service so different that your competitors can't match them.
Systems to Focus on Market Niche
Through the use of datamining, WorldWide's Product Research Department determined that
most moms wanted a candy bar that didn't melt so fast and mess up kids clothes or the furniture. Since
our Information Systems are integrated throughout the company, our Knowledge Workers were able
to alter the recipe for Cybernuts to keep the chocolate in a more solid state. Now we can use focused
differentiation in our promotional advertising by telling potential customers that the chocolate won't
melt so fast.
We also have useful information from our integrated Information Systems that tells us
consumers want a bigger candy bar for the same or a lower price. We can now differentiate Cybernuts
as being bigger than the competition's candy bars, therefore better, while the price is the same as the
competitor's smaller candy bar.
Supply Chain Management and Efficient Customer Response Systems
Because of the tight link WorldWide has developed with SugarSweet Refiners, WorldWide
has significantly reduced the cost of its product. Because of the integration of Information Systems
throughout the organization, it can reduce costs and price Cybernuts well below the competition's
candy bar. And because of the Information System WorldWide has developed with the convenience
stores, the stores never have to worry about running out of Cybernuts because WorldWide will know
to ship more product when the stock falls to a preset level. Supply chain management offers new
opportunities for companies to integrate with suppliers and customers and lower costs for everyone.
Since WorldWide Candy doesn't grow its own sugar cane, it must purchase the refined sugar
from a supplier, SugarSweet Refiners. WorldWide buys a lot of sugar, as you can imagine. If it
develops some kind of link with SugarSweet that is mutually beneficial to both sides, then each one
can reduce costs but also develop a pricing policy that gives WorldWide significant cost savings. So
WorldWide and SugarSweet decide they will use an integrated Information System that replaces the
old-style purchasing paperwork with electronic billing and shipping.
WorldWide Candy now places sugar orders via an electronic system that is tied directly to
SugarSweet's electronic shipping system. Neither company has to process paperwork for orders or
deliveries. Look at all the time and money both sides are saving, not to mention the reduction in errors
that are inherent in any manual system. However, by tying into this method of ordering and
delivering, it will be very expensive for WorldWide to find another sugar supplier. It will also be a
significant loss to SugarSweet if it loses WorldWide as a customer because now it will have to find
another company and set up the same system. So both sides are locked into this mutual system.
On the flip side, WorldWide knows that it costs five times as much money to get a new
customer as it does to keep an old customer. It decides to lock in its customers (in this case
convenience stores that stock Cybernuts candy bars) by making it more expensive for that customer to
switch to the competition. WorldWide offers to keep all the sales statistics for products on its
Information System and to give that information to customers when it's convenient and in the format

they require. That way the store doesn't have to track data and spend the money to process them into
useful information. Through WorldWide's information system it, and not the convenience store, can
keep track of stock levels and know when more products are needed. Through this agreement,
WorldWide develops a link to customers that the customer finds extremely useful.
You see, switching costs, as described in this section, works both ways: between suppliers
and companies, and from companies to customers.
8.4 Firm-Level Strategy and Information Technology
Think of a picture puzzle with all its separate pieces scattered on the table. Separately, the
pieces don't make a very pretty picture. But if you fit them together, they make quite a beautiful piece
of art. So too for businesses. Separately, the various units of a business don't function well and
certainly aren't successful on their own. But if you fit them all together, so they work in conjunction,
you can create a successful business. Information technology can help you do this.
What does a business do better than anyone else? Does it make the best jeans in the world?
Do they produce the best movies? Does it deliver flowers faster and fresher than any of the
competition? Whatever its main product or service is, that's its core competency. Successful
companies can use information technology to improve their core competencies by sharing information
across business units. They can also use technology to expand their core competencies by using
knowledge stored in their information systems.
8.5 Industry-Level Strategy and Information Systems: Competitive Forces and Network
Economics
Look at the relationship between America OnLine and Microsoft. On one hand, they are
fierce competitors, going head to head in attracting Web users to their respective Web sites. On the
other hand, they work together to supply Web users with desktop icons for accessing the Web. How is
it that they can compete so vigorously in one area and yet cooperate so well in another? Because both
make sense and make money for each company.
Information Partnerships
Many times it's more productive and cheaper to share information with other companies than
to create it yourself. Information partnerships between companies, even competitors, can enhance a
company's products by aligning them with an industry-wide standard. Vehicle tire manufacturers form
information partnerships to share information about standard widths and sizes of tires. Can you
imagine how difficult it would be for consumers and other businesses if each tire maker built tires
differently?
Other companies form information partnerships to add extra elements to their products which
they couldn't offer on their own. Lots of companies offer credit cards with their logo and company
information. They then share customer information with the credit card companies. Both companies
win because they can offer extra services and products not available if they had to act alone.
8.6 The Competitive Forces Model
One way you can help your company compete is to have more information in a better form
than the competition does. If WorldWide happens to know that the price of sugar usually falls in mid-
summer, it can plan ahead and get a better price for the ingredient. Simply put, good information in a
timely manner can help you win the game.

The competitive forces model
• Threat of new entrants into its market. The upstarts can give you fits when you least expect it -
Amazon.com is a good example.
• Pressure from substitute products or services. Even if they aren't better than your product,
substitutes may be cheaper and customers will be enticed by the lower price.
• Bargaining power of customers. The Internet offers customers a unique opportunity to quickly
and easily compare prices.
• Bargaining power of suppliers. New technology offers suppliers the chance to integrate
information systems that tie them closer to their customers.
• Positioning of traditional industry competitors. Efficient business processes can give
companies the edge they need to place themselves in the lead.
Network Economics
You decide to throw a big party and invite a hundred of your closest friends. You buy tons of
food and beverages-lots more than you really need. At the last minute, Sam calls and asks if he can
bring his brother who unexpectedly dropped by. You agree since you won't have to purchase more
food. The marginal cost of one more guest at your party is zero.
That's how network economics work. If you build a network for a thousand users, adding one
more probably won't cost you anything. However, if you add the second thousand users, you'll incur
the cost of adding those extra users. The more users you add, the more your community is enriched.
Allowing Sam's brother to attend your party enriched the experience for all, since he is a very popular
rock star who plays excellent guitar!
Many companies doing business on the Internet are realizing the value of network economics.
They build Web sites to attract customers and then keep them coming back by providing chat rooms
and other services for the customers. It doesn't cost much more to add these extra features, since they
have already built the Web site and have the hardware available. However, the additional customer
information they gather from the chat rooms and information forums is invaluable.

Using Information Systems can help a company beat the competition through differentiation and
providing services that are valuable to both customers and suppliers. Companies can also use
Information Systems to reduce costs below those of the competition and to improve core
competencies.
8.7 Using Systems for Competitive Advantage: Management Issues
Using Information Systems to beat the competition and increase the value of your product is
not easy at all. It requires changing processes and methods that probably have been in the organization
since time began. The responsibility for successfully developing and then using an integrated
Information System will usually fall to the managers throughout the organization.
Managing Strategic Transitions
The changes taking place in an organization affect both the social element and the technical
element of the organization and are strategic transitions. When your company installs a new
information system, some people will lose their jobs, managers may be reassigned, hopefully you'll
gain new customers, and your relationship with your old customers may change. At the very least,
when a company installs a new system, the business processes should metamorphose to accommodate
the new technologies.
Retail businesses realize the value of vender-managed inventory and are eager to embrace it.
Convenience stores and grocery stores give the responsibility for stocking shelves to their vendors.
Tying those vendors into the store's information system gives the vendor critical information about
stock levels and the pace of sales. Inventory costs for both retailer and vendor are reduced and the
quality of information improves for both.
What Managers Can Do?
The important thing to remember is the need to pay attention to the industry to which your
business belongs. Look at what others are doing and how they're doing it. What are they doing right?
What are they doing wrong? What can you do better than your competitors? What technologies can
you exploit that the rest of your industry isn't using? Observe the following questions that managers
should ask when identifying and developing a successful Information System. Take a moment to
review them.
• What are some of the forces at work in the industry?

• How is the industry currently using information systems?
• Which organizations are the industry leaders in the application of information systems
technology?
• How is the industry changing?
• Should the firm be looking at new ways of doing business?
• Are significant strategic opportunities to be gained by introducing new information
systems technology?
• Is the organization behind or ahead of the industry?
• What is the current business strategic plan, and how does that plan mesh with the current
strategy for information services?
• Does the firm have the technology and capital required to develop a strategic information
systems initiative?
• Where would new information services provide the greatest value to the firm?

A well-developed strategic Information System that is integrated throughout the company can
be used to lower costs overall and provide greater value to the company, the supplier, and the
customer.
The Challenges in Strategic Management
ο Management is about:
- Knowing what you are trying to achieve
- Getting results
- Taking decisions
- Working with, motivating and enthusing people
- Finding creative ways to achieve new objectives
ο Finding creative ways to achieve existing objectives
ο Not fundamentally intellectual like the theory of relativity or astrophysics

ο But being intelligently practical, in the sense of:
- Getting the outcomes you want when you do not control all the action
- Rarely having complete information
- Often having multi-faceted situations with complex links and trade-offs to deal with
- but then decisions have to be distilled into a few ‘bold messages’ if real people are
going to
ο be able to absorb, understand and be motivated to action
- Having to handle those exciting, creative, disobedient, frustrating things called
people
So what should students know about in order to be more effective in the ‘strategic
management’ world?

The information systems are designed in such a manner to give answers to all these questions. Once
we get the answers we will be in a better position to formulate a successful strategy which will
definitely gain a competitive edge over other companies.

Review Questions
1. How can managers use Information Systems to develop tighter relationships with suppliers
and customers?
2. How can managers use Information Systems to play a strategic role in their organization?
3. Explain how a company can use Information Systems to improve its core competencies.

1. Provide three examples of IT being used to build a barrier to entry for new products or
competitors.
2. Discuss the idea that IS by itself can rarely provide a sustainable competitive advantage.
3. Give two examples that show how IS can help a defending company reduce the impact of the
Competitive forces model.
1. Consider a small service firm such as a physician, dentist, accountant, or lawyer. Is it possible
for such an office to use computers to gain a competitive advantage? To start, identify the
customers, suppliers, and rivals. Do you think the “natural” switching costs are high or low;
that is, how often do customers switch to competitors? Which of the major techniques do you
think would be the most successful (barriers to entry, switching costs, quality control, lower
prices, ties to customers or suppliers, etc.)?
2. Pick an industry. Find two firms in the industry—one a technology leader, the other a
follower. Get the financial information on those firms for the last five years. Find analyst
summaries of their operations. Compare the two firms. Are there differences in finances,
operating methods, or customers?
3. If you are managing one of many small suppliers building products for an industry dominated
by a few large firms (for example, you run an auto parts supply company), what strategies do
you have available? In particular, what can you do to protect yourself in a downturn that
affects the parent industry?

UNIT I
Lesson 9 – Strategic Analysis
Learning Objectives
1. To know company’s interaction with the business environment through external agents
2. To learn the methods of obtaining a competitive advantage
3. To study about the uses of Information Systems in gaining competitive advantage
9.1 Introduction
In some ways, information systems designed for competitive advantage are not much
different from transaction-processing and decision support systems. In many cases, advantages
over your rivals can result from changes in the basic transaction processing systems and business
methods. The real difference with strategy lies in its goal: to change the way the business operates
and gains an advantage over the other firms in the industry.
Creating strategic systems requires that you understand the entire firm and its relation-
ships with external agents in the environment, such as suppliers, consumers, workers, and rivals.
Many systems have been devised to help you analyze and create corporate strategies. A common
thread in gaining a competitive advantage is to improve the ties and communication with
suppliers and consumers. Electronic communication can provide automatic data collection,
minimize errors, and create faster responses.
Information systems can provide a competitive advantage through increasing the barriers
to entry and controlling distribution channels. Services from information systems can be used to
differentiate, your product from the others in the market or even to create entirely new products.
Computer systems might give you an edge through low-cost production or, improved quality
management.
Designing strategic systems can be a dangerous task with many opportunities to fail. One
complication is that development costs are high. Some strategic systems use new technology,
which carries higher costs and a greater risk of incompatibilities and other problems.
9.2 Competitive Environment
One of the important trends facing most businesses today is the increased level of
competition. Improved telecommunications and faster delivery services mean that local firms
competition from regional, national, and international firms. Local firms have to compete against
national mail-order companies, which offer wide selections, next-day delivery low prices. The
Internet, home shopping channels, and toll free phone numbers make it easier for consumers to
compare prices, putting pressure on all firms.
Large national retailers and franchises put pressure on-local stores. They also compare
against themselves for market territories. Their size gives them leverage in dealing manufacturers.
By purchasing in large quantities, they can negotiate lower prices. Their volume also makes it
easier for them to buy from foreign producers.
Several international trends are creating increased competition. The internet search for lower
manufacturing costs puts pressure on firms to cut their costs. For instance, the Japanese have
moved production to other Asian nations to build television sets. Decreasing trade barriers
throughout the world also creates larger markets.
9.3 External Agents

Competitive advantage can be gained by establishing or changing relationships between

firm and its external agents. External agents consist of suppliers, customers, rivals, potential new
entrants, substitute products, and sometimes the government. From a systems perspective, each
of these entities is outside the control of the firm. Yet they strongly affect the company. Through
proved ties to these agents, they become part of your system, which can be used to improve the
competitive position of the firm.
Customers
The intermediate layers also cause confusion about what the customers want because it is
hard to identify the customer. To the manufacturer, is the customer the wholesale firm that buys
the products, the retailer, or the final consumer? It is often wise to focus on the final consumer,
but the manufacturer has to consider the needs of the retailer as well. For example, in the bicycle
industry, one company found a new way to package its bicycles so that they could be assembled
(by the retailer) in half the normal time. This particular situation helped both the retailer and the
final consumer, but imago what happens when the manufacturer receives conflicting demands
from the various "customers."
An important goal in any company is to satisfy the customers. If there are many layers of
buyers between the company and the ultimate consumer, it can be difficult to determine what the
customer wants. Similarly, the layers create delays that make it difficult for the retailer to order
and obtain the products. For example, with older, slower manufacturing processes, merchants
have to place most orders for the Christmas season around July-five or six months before the
sales would occur. What happens if the economy changes or some event causes people to
suddenly demand a different product? The retailer, manufacturer, and customers all suffer as a
result of these long lead times.
Suppliers
Suppliers can provide individual parts, entire products, or even services (such as a bank
that lends money). Three major issues involving suppliers are price, quality, and delivery sched-
ules. Just as with customers, problems can arise when there are many layers of suppliers. For
instance, increased layers can result in longer delays between ordering and delivery because the
supplier has to contact its supplier, who contacts its supplier.
Rivals, New Entrants, and Substitutes
The goal of a strategic approach is to derive a competitive advantage over the rival, or
other firms in the industry. There could be many competitors or just a few larger rivals. The com-
petition could take place in a small town, across a nation, or worldwide. One of the first steps in
any strategic analysis is to identify the primary competitors and to assess their strengths and
weaknesses.
A related issue is the concept of potential competitors or entrants in the business. In some
cases, you might identify the major rivals, implement a strategy, and then immediately lose
everything as new firms enter your business. Entrants might build their firms from scratch, such
as the way Burger King built new stores in the same areas as McDonald's restaurants.
Alternatively, other firms may increase the sales of products that are similar to your products.
Substitute products are related economically by the degree to which consumers are willing to use
one product instead of the other. A classic example comes from the late 1970s, when the U.S.
economy faced high inflation rates and banks were subject to limits on the interest rates they
could pay on deposits. Merrill Lynch, the stock brokerage firm, introduced a service enabling
customers to store their money in a wide variety of financial instruments that paid significantly

higher interest rates than did checking accounts, and still write checks on the account. Many
larger customers took their money away from banks and put it in these asset accounts. These new
accounts were perceived as close substitutes for traditional bank services, and people transferred
huge sums of money out of the banking system
Government Regulations
In any economy, government intervention has a strong influence on the firm. There are
myriad government agencies, regulations, taxes, and reports. The situation multiplies for multi-
national firms that are subject to the regulations of many nations. These agencies and regulations
can have strong effects on the profitability of a firm. Generally, an individual firm has no control
over government regulations, but sometimes suggestions can lead to modifications. For instance,
it is now possible to submit some documents to government agencies in computer form. In fact,
some reports (such as financial reports) are required to be filed electronically. Electronic forms
can decrease your storage costs and make it easier to find documents that have been stored for
long periods of time.
9.4 IS Techniques to Gain Competitive Advantage
Competitive advantage may be achieved with many techniques in business. Information

technology is one area that may provide several opportunities. In general, MIS techniques may
not be better than other methods. However, some firms have experienced considerable success
from using these techniques, so they are well worth considering.
Additionally, the rapid changes in technology often lead to competitive advantages if
your firm is the first to find a creative use for the new technology. The other side of the coin is
that untested new technologies may not work as planned. Hence, the pioneer is taking a risk: If
the project fails, the development costs may put the firm at a competitive disadvantage
The question we wish to examine is how information systems can take advantage of these
techniques. The fundamental mechanisms for gaining competitive advantage are barriers to entry,
switching costs, lower production costs, product differentiation, control over distribution
channels, innovation, and quality control.
Sources of Barriers to Entry

• Economies of scale (size)
• Economies of scope (breadth)
• Product differentiation
• Capital requirements
• Cost disadvantages (independent of size) Distribution channel access Government policy
Barriers to Entry
The additional costs of creating a sophisticated information system make it harder for firms to
enter the industry.
• Distribution Channels: Control over distribution prevents others from entering the
industry. Consumers are reluctant to switch to a competitor if they have to learn a new
system or transfer data.
• Lower Production Costs: Using technology to become the least-cost producer gives an
advantage over the competition.
• Product Differentiation: Technology can add new features to a product or create
entirely new products that entice consumers.

• Quality Management: Monitoring production lines and analyzing data are important
aspects of quality control. Improving quality leads to more repeat sales.
• The Value Chain: Evaluating the entire production process identifies how value is added
at each step. Combining steps or acquiring additional stages of the value chain can lead to
greater profits.
9.5 The Search for Innovation
Industry and academic leaders are constantly searching for ways to improve
organizations and gain a competitive advantage. Illustrated by Figure 10.8, one method to
organize the search is to examine the primary processes of the firm: research, engineering and
design, manufacturing, logistics and supply, marketing, sales and order management, service, and
general management. Each of these processes has its own inputs, outputs, and objectives.
Analyzing them in detail enables managers to spot problems and to search for innovative
opportunities
The following sections present general ideas for each of these processes that have
generated interest and some success. Most of them use technology to improve the process or to
help the processes work together better. Keep in mind that any firm, there can be many ways of
improving processes. Relying on information technology is not always the best answer
Research
IT support for research takes the form of computer analysis and modeling, statistical
analysis of data, project management and budgeting, and workgroup technologies that make it
easy for researchers to collaborate and share information with each other and with managers
throughout the company.
Research in firms varies enormously depending on the industry and the overall corporate
strategy. At a minimum, most firms at least have a product development team that is constantly
searching for new products or improvements in existing products. Some companies like 3M,
DuPont, AT&T, or Intel, spend considerable sums of money on basic research to create entirely
new products. To these firms, strategic advantage comes from being the leader in the industry
with a constant cycle of new products
Engineering and Design
Engineering and design processes are responsible for converting theoretical research into
new products. Engineers establish manufacturing procedures, design new equipment, and
coordinate suppliers with production. In particular, the design process must optimize the
production line to minimize costs and retain high quality
Manufacturing
There are four key features to production: costs, speed or timing, quality, and flexibility.
Competing through lower costs and higher quality are time-honored means of gaining a
competitive advantage. They might not be sufficient today. Increasingly, firms are turning to
mass customization in an attempt to gain market share. Twenty or 30 years ago, the large firms
in an industry were content to build huge plants, gain economies of scale, and aim at the mass
market. This approach tended to leave niches open for competing firms. The problem with this
strategy is that it allows rival firms to gain a toehold, which they might use to build market share
and eventually compete directly against your primary market. Today's firms are trying to shift
production fast enough so that they can cover virtually all of the niche markets.

Logistics and Supply
The implementation of just-in-time (JIT) inventory systems is largely credited to

Japanese manufacturers. Today they are used by manufacturers worldwide. Manufacturers
attempt to cut costs by holding minimal inventories. Instead, inventories are maintained by the
suppliers, who deliver the products to the assembly line just as they are needed. The system can
only work if the suppliers and factories are linked electronically-often there is only a one or two-
hour delay between ordering and delivery.
Marketing
A well-known application of IT to improve marketing is the use of frequent-buyer

databases that identify major customers. More traditional point-of-sale transaction systems can be
leveraged by identifying preferences and rapidly spotting patterns or trends. At the tactical level,
expert systems are used to help analyze data and perform statistical trend analysis. Geographic
information systems are being used by leading firms to identify patterns and possibilities for new
sales. Information systems can also be used to link firms more closely to external marketing firms
for research data, communication, and development of promotional materials.
Sales and Order Management
Sales and order management are often handled simply as an operations or transaction
processing area. However, in the last 10 years, several firms have used technology to gain a
competitive advantage by improving the way they handle sales and orders. Frito.-Lay's use of
handheld computers is a classic example. The systems enable managers to more closely track
their own sales, sales of competitors, and other external factors, because salespeople can enter
data immediately. For certain industries, the concept can be extended further to installing
workstations at the customer sites that tap into your central databases. Federal Express and Baxter
Healthcare both used this technology to gain a leadership position.
Service
Service industries and service-based processes (like accounting, MIS, and law) have their
own problems and opportunities. Technology is used to support services with on-site, portable
computers. These systems enable workers to have complete access to information almost
anywhere in the world. Leading companies are building specialized databases to support their
service workers, such as the "answer line" databases that support General Electric and Whirlpool
customer service representatives.
Management
Executives are also increasingly turning to electronic conferencing tools and workgroup
software, even e-mail. Executives can cover more areas and deal with more people with these
systems than they can by phone or through face-to-face contact. Some studies have shown that, in
traditional conversations, managers spend as much as 50 percent of the time on personal chit-
chat. Electronic systems (although they might be less personal) tend to be more efficient. On the
other hand, some companies have been restricting employee access to electronic networks
(especially the Internet) because they waste too much time on personal communications.
Larger firms are building electronic links to their strategic partners, for instance, by pro-

viding electronic access to corporate data to accounting and legal firms. These links enable the
external partners to keep a closer eye on the firm, speeding the identification of problems and
assisting them in spotting broad patterns and opportunities.
9.6 Summary
Information systems can provide benefits beyond traditional cost saving. Competitive ad-
vantages can be gained by creating barriers to entry and gaining control over distribution
channels. Using information systems to build ties to suppliers and customers can provide lower
costs and better quality products. Computer systems also provide incentives for customers to
remain with your company if they incur costs of learning new systems and transferring data when
switching to a competitor. Information systems can also be used to differentiate your products
from the others in the marketplace. Similarly, innovative services offered with the help of
technology can entice customers and expand your market
You can search for competitive advantages by examining Porter's external forces of ri-
vals, customers, suppliers, substitute products, and new entrants. You can also search for
strategies in research, engineering, and design. In manufacturing, you can look for ways to
decrease costs and improve logistics. In marketing, potential gains can be found in better un-
derstanding of customer wants, as well as sales and order management. Services can be supported
through better information flows and workgroup products. Management can be helped with better
data and better decision tools
Strategic systems face many risks. They tend to be expensive and difficult to create. Any
gains created may disappear when competitors pick up the technology and imitate your offerings.
Additionally, making strategic changes to your firm might alter the industry, which might
adversely affect your firm. And if these problems are not enough to discourage you, remember
that attempts to monopolize a market are illegal, so you have to make sure that your plans do not
violate governmental regulations.

UNIT II
Lesson 10 - End User Computing (EUC)
Learning Objectives
1. To study the concept of End-user computing and its application in Information System
Development
2. To identify the components of End-User Development
10.1 Introduction
The main objective in introducing this topic is to ensure that you understand the vital role that
the concept of EUC can play in the strategic management of organisations if it is managed effectively,
and the enormous damage it can do if it is not. Traditionally, the only people who had direct contact
with computers were the systems professionals (programmers, systems analysts etc.). The
introduction of personal computers, terminals, networks, user-friendly software, databases has altered
the position dramatically and has led to the growth of end users
Most people experience computers as "end-users" of packaged programs. Unfortunately the
writers of these programs can't know the details of the job you are trying to do. Trying to meet the
needs of diverse users, they bloat their programs with hundreds of features most people never use.
Life (and programs) would be much simpler if each user could add the functions she wanted.
Providing this capability in a program is not trivial. The programs must be designed to accept
user-written components in appropriate places. There must be a way to store and manage them. Most
important, since most users do not have the time or inclination to learn the tools and skills of a
professional programmer, reasonable compromises are required. The expressiveness and generality of
full-fledged programming languages are traded for usability by a variety of metaphors and tricks.
Programming can be done much more easily within the metaphor -- a desktop with file cabinets and
wastebaskets; a formula of spreadsheet locations or mathematical symbols; a sequence of GUI
actions; a circuit diagram; an application-specific language -- than with conventional programming.
Because the appropriate metaphors, with their capabilities and limitations, differ widely
depending on the users and their purposes, there is no one method of end-user programming. Instead
there is a variety of techniques, such as Programming by Demonstration, visual programming, and
many domain-specific languages and formalisms. Ideally there is a smooth progression from simple
but limited metaphors, to more complex and powerful techniques as the user-programmer advances.
Computing usually adds to its provision rather than replacing one approach by another. This is
equally true of end-user computing and the end-user is now involved in all of the above ways. This set
of notes seeks to address the questions of "who is the end-user", "what kinds of end-user systems are
there", "what support should be given to end-user at the various levels of the company", "the need for
an adequate human-computer interface for the end-user", "software provision for end-users" and the
problems that end-users can generate for the company.
10.1 What is EUC?
We will see the meaning of the term “end user” as a user of an application program.
Typically, the term means that the person is not a computer programmer. A person who uses a
computer as part of their daily life or daily work, but is not interested in computers as such. When
end-users, who have not necessarily been taught how to write code in conventional programming
languages, write computer programs. Examples include spreadsheet users who write formulas and
macros.
EUC is an environment in which the user has free control and latitude over the process. He
may use data that is interchanged through the mainframe of the MIS division, or he may create his
own data. But he is in control; he is responsible for the product and the effectiveness of the use of the
equipment. It has since been suggested that the only distinction between EUC and corporate

computing is the reporting relationship within the Organisation. Computing which reports directly to
the Information Systems function is corporate computing; the rest is EUC.
10.3 End-User Development (EUD)
Specifically, the practice of users developing their own information systems, is often but not
always with the support of professional systems developers. The practical involvement of end-users in
application development necessitates the easy access to computing facilities. This may be
• Timesharing on a centralised mainframe
• The use of stand alone personal computers
• The use of personal computers which are connected to local area networks and mainframes.
In addition to being provided with hardware and software, extra facilities are a necessary condition of
successful End user applications development. In particular:
• Education and training on the use of software tools
• Assistance in the technical aspects of writing, testing, and debugging applications
• Availability of reference material
• Aid in accessing the corporate database
10.4 Why End User Computing?
The major advantages attributed to EUC include:

(a) Enhanced productivity of professional and white-collar workers.
(b) Overcoming the shortage of DP professionals.
(c) Provision of user-friendly and responsive systems.
(d) Overcoming the implementation problems by transferring this process to the user.
System implementation has always been a major problem for developers. If users develop
their own systems, clearly the implementation problem goes away.
Who Are The End Users?
In general an end-user is anyone who has to interface to a computer who is not employed
specifically to do so (ie is not a data entry clerk or an operator). This includes executives interfacing
to EIS facilities, middle managers or technicians who use a PC or a terminal to an on-line system,
clerks accessing a central database to download data for local processing, individuals using a PC in
stand alone mode for their own work, individuals using a PC in stand alone mode for an activity
which the corporate management has decided shall be done by computer (eg office automation),
clerks interfacing to a computer system which has replaced their manual system (without their having
any input) and clerks writing data preparation documents.
Web integration is, however, creating a new class of end-user. (S)he is an end-user in one
organisation who, through integration (3-tier client / server), has suddenly become a user of a system
in another organisation. A further complication is that now a system may have to cope with two
different kinds of end-user at the same time. For example the parcel tracking system at FEDEX could
be accessed by both a company employee and an external customer, both trying to track a parcel
(though not necessarily the same parcel). We may group them into the following categories:
• Non programming
• Command level
• End-user programmers (including senior management professionals)
• Functional support personnel
• End user computing support personnel
• DP Programmers
This list covers a very wide range of personnel carrying out a wide range of tasks throughout
organisation - and the list continues to grow.

Why are they end-users?
When the large data processing type applications (payroll, inventory etc.) had been developed
on large machines, a demand arose for Management Information. The users were potentially
sophisticated professionals.
As stated above, the traditional IS department development time was too long, and there is a shortage
of trained analysts and developers.
IS customers are often dissatisfied with the performance of delivered application systems:
• These systems often take so long to develop that organisational and/or market
requirements have completely changed by the time they are made available to the users.
• Even though significant care is taken by trained analysts to ensure that user requirements
are well defined, it is often the case that misunderstandings occur.
• The traditional methodologies generally do not allow requirements to be changed during
development, whereas in practice, the systems requirements are often unstable, requiring
a flexible approach to analysis and design.
• The very fact of the existence of a new system will change the environment in which that
system exists, prompting the emergence of changing requirements.
Applications Suitable for End-user Development
Applications suitable for end-user development can be grouped into the following 5 categories:
• One time enquiries
• Simple Reports
• Minor Changes to Reports or Enquiries
• Presentation of Data in Alternate Forms
• 'What if' Analyses
Applications not suitable for end-user development:
• data entry involving organisation files and databases (where the data must be validated for
accuracy and reliability)
• high volumes of transactions, requiring processing efficiency and multiple processing
steps
• use of 'traditional' computer languages designed for use by professional programmers,
requiring detailed statement of processing procedures and controls
• changing of data values in existing databases and files
• applications spanning several departments or divisions in the organisation
• applications requiring formal documentation
• applications requiring a long development process
• applications requiring detailed formal specifications.
Risks in End User Computing

• Errors in analysis. Poorly trained End-users often are incapable of correctly analyzing
data or systems .Resulting DS software is therefore often of questionable quality.
• Lack of documentation. Most End-users are not trained in formal techniques of analysis
and design. Documentation is often inadequate or even non-existent, making maintenance
difficult and expensive.
• Faulty Model. Many Decision Support Systems (DSS) rely on corporate models
developed by End-users for use with spreadsheets. Recent research has indicated that as
many as 38% of these spreadsheets may contain errors. As these systems are used by
senior executives as aids in strategic decision-making, the consequences are not difficult to
asses
10.5 End User Computing Tools

There are 2 major classes of End User Computing tools:

• application packages
• fourth generation languages
Application Packages
These are pre-written software packages that are marketed commercially. They are available
to support common business functions such as payroll, purchase ledger, sales ledger, production
scheduling, inventory control etc. Many of the packages allow for some customization through
specification of key parameters (eg discount % for prompt payment).
Fourth Generation Programming Languages
These languages allow users to develop their own computer programs and even link a series
of them together to form a small system. These languages can be run on most types of computer.
There are many classes of fourth generation languages:
• query language/report writers
• graphics languages
• statistical analysis packages
• decision support/financial modelling tools
Implications of EUC
• Levels of end users in terms of capabilities

o menu-level end users
o command-level end users
o end-user programmers
• functional support personnel
• EUC application considerations
• shifts workload so that end-users and information specialists’ talents are better used
• reduces communications gap
10.6 The Models of End-User Systems
The above discussions of end-users identify clearly the different kinds of end-user system
provision. They may be summarised as follows (the word terminal is used here to distinguish a local
facility on which no local processing is done from one on which local processing is done - the form of
the device is irrelevant):
(a) On-line terminal for specific information provision;
(b) On-line terminal for general information provision (eg a terminal to an on-line database
such as LEXIS);
(c) On-line terminal used as part of a self organising group activity, either via a terminal to a
mainframe or through a LAN (eg diary management, document preparation);
(d) On-line terminal which is being used as part of a wider corporate system, such as the
manager's terminal in one store of a department store chain or an order entry terminal in an
on-line transaction processing system such as a booking system;
(e) A PC which is being used for an individual's own work, which may (at some times) be used
as a terminal in any of the above ways (the manager in the department store may be doing
spreadsheet work as well as reconciling the days takings) - this is the conventional
client/server situation;
(f) as (d) but where the PC is completely stand alone and, probably, used only for a single task
such as word processing;
(g) a sophisticated workstation such as a graphics design workstation, where there is
interaction with other users but where the operation is more akin to (b) than to (d);
(h) a small computer, such as a notebook, used either for mobile use (eg British Gas manuals)
or intermittently (eg a travelling salesperson);
(i) devices operated directly by the public, such as an ATM or a kiosk;

(j) general purpose terminals, as in (b) or (d), but where the end-user is a member of the
public.
10.7 End-User Systems Tools
The following list indicates some of the tools to which end-users have access and for which
they may need support.
(a) Text and multimedia handling tools – word processing, desk-top publishing, web-
publishing, presentation software, document management systems, work-flow
management systems;
(b) Data handling tools – spreadsheets, statistical packages, decision support systems,
databases;
(c) Communication tools – electronic mail, voice over IP, fax, WAP, pagers;
(d) Office automation tools – diary management, electronic notebooks, directories, project
management tools, personal digital assistants, bluetooth;
(e) Group systems / computer supported collaborative work – teleconferencing;
(f) Graphic design – graphic software, computer aided design;
(g) Knowledge management – expert systems, data mining, information retrieval,
intelligent agents.
Supporting the End-User
The organisation of an MIS department centred on the needs of the end-user was covered
earlier in the unit. This section looks at some other aspects of end-user support which follow from the
above list of models of use.
(a) End-user computing now includes general purpose office automation. In order to operate
effectively this type of application must include top management and must be supported
by top management.
(b) Systems are increasingly being used, not by clerks employed specifically for data entry
but by staff using them as just another tool in their normal jobs. If the tool is not seen to
be effective then it will not be used. It is essential that end-users are much more fully
integrated into the system design process and that prototyping methodologies are
adopted. The most important aspect of the systems design, after functionality and
flexibility, then becomes the interface design.
(c) The Information Centre concept is directed primarily at those end-users who
are using PCs for their own personal work. Users who are using stand alone PCs as part
of their job (eg word processing in the typing pool) must be given detailed training
programmes and must be involved in key decisions (eg on what package to standardise or
where to site the communal printers). This includes induction training for new staff.
(d) A particular problem with the Information Centre concept is where the
provision of end-user support has been contracted out to a third party, either as a
straightforward outsourcing deal or because the software being used has been provided
by a third party and the third party is providing the help to the users of that software.
(e) Users of external information sources need as much support as those in (c). They tend to
get forgotten since, usually, they are difficult to track.
(f) Packages such as decision support software (eg mathematical modelling, decision
support trees, etc) may get omitted if not carefully targeted. Where is the control for
generating adequate EISs? Again if this is not clearly identified then much needed
systems may be ignored.
(g) It is not possible to provide training for end-users who are not members of the
"company" (ie the general public). It is essential, therefore, that any user interface is both
"naive user" and security foolproof, as well as being simple to use. It is important also
that any device to be used by the general public provides added-value. If it does not then
it will not be used.

(h) New technologies (eg Web Services) are emerging all the time. A programme of
education is as important as any training.
10.8 The Information Centre
One major requirement which is now needed is support for that class of end-user that is
working alone but on a task which is strategic to the organisation. This is normally provided in the
form of an Information Centre, which is both a place (often known as the "help-desk") and a group of
people. The Information Centre owes its existence to the problems which end users created when PCs
first came into offices about fifteen years ago. Now the role has more to do with establishing and
enforcing the role of PCs in meeting the IT strategy than just supporting the end-user. For example,
the information centre must take the lead in ensuring that personal computers are not the Achilles heel
when it comes to data protection. The concept of the Information Centre was launched early in the
1980s when end-users were quite naive. Today, a number of organisations are establishing "self-help"
groups from among the more sophisticated of their users. Unless the members of the group are
"hybrids", however, they are still going to need considerable IT technical expertise to back them up.
With the emergence of the Web and the Intranet much of the work of the Information Centre can be
replaced by a suitably designed Intranet Site. On the other hand, access by customers and access by
employees of other organisations demands a much higher level of involvement in the support
provided. Full details of the background to and the operation of an Information Centre are as follows.
Problems
It became clear very quickly that the managers had bought something that they didn't
understand and either had to discard the machine (as happened in many schools who were encouraged
by government to acquire computers) or had to be supported to get the most out of their purchases.
The particular problems which were posed for the organisations into which these PCs had been
introduced were:
(a) Lack of standardisation between the various purchases leading to:
(i) inability to share data;
(ii) no economy of scale in purchasing;
(iii) a variety of requirements for maintenance, in the few cases where the problem had
actually been considered.
(b) Lack of control over the requirements of legislation, such as software copyright, data
protection, health and safety and the specific legal constraints covering the organisation.
(c) Demands for assistance with:
(i) systems analysis and design;
(ii) programming;
(iii) software procurement;
(iv) sizing - machines which have been purchased but are too small for the job;
(v) maintenance;
(vi) fall-back;
(vii) lack of documentation;
(viii) data security;
(ix) environmental control;
(x) file conversion and data acquisition;
(xi) data organisation.
The Information Centre

The term "Information Centre" was conceived by IBM as a way to support not only PCs but also those
users who wished to obtain, and process (possibly using fourth generation languages), data which was
held on a central corporate database. The Information Centre was to be:
"A small group of specialist personnel whose brief is 'to support and promote the use of personal
computing throughout the organisation'".
In particular the Information Centre would:
(a) support personal computing using PCs or 4GLs by:

(i) offering advice and support to the individual;

(ii) defining standards and undertaking corporate activities (eg arranging maintenance)
for the organisation;
(b) organise and supply data to the individual either from the corporate database or from
national or international databases.
The Physical Centre

The Information Centre would be a physical entity, not just a conceptual entity. There would have to
be a location to which people could go for advice and demonstrations. The Centre would consist of:
(a) A physical centre, which would have:
(i) a reception area with a desk or window at which to receive enquiries;
(ii) a demonstration room equipped with a variety of up-to-date PC equipment and software;
(iii) a library with software and documentation;
(iv) offices for a manger and systems analysts;
(v) a workshop for technicians.
(b) A group of staff comprising:
(i) an Information Centre manager;
(ii) receptionist(s)/secretary;
(iii) librarian/demonstrator;
(iv) a small group (say 3) of analysts/programmers
(v) a small, group (say 2) of technicians.
The exact composition of the staff would depend on the size and the physical structure of the
organisation. The above would be appropriate for a single site organisation with a turn over of about
£M100 per annum.
Management Structure
In organisations where the Computer Centre already reports directly to the Board (ie there is a
Chief Information Officer) the Information Centre is normally part of the Computer Centre. In
organisations where the Computer Centre reports to some other function (eg finance) the Information
Centre is usually independent and reports directly to the Board. A structure which is becoming
common now is for the Chief Information Officer (a Board level appointment) to be responsible for:
(i) a strategy group;
(ii) the Information Centre, and
(iii) the Computer Centre.
This arrangement allows the end-users to see the Information centre as independent from the
Computer Centre, yet still provide a co-ordination mechanism.
Skill Requirements
The kind of skills needed by computer professionals in the Information Centre is quite different
from those working in the conventional data processing department. A deep knowledge of software
packages, communications, contract matters and trouble shooting is more important than information
gathering, although conventional analyst or technician skills are required to some degree.
System Development
Panko identifies five environments in which development for end-user computing is taking
place. These vary from DP systems through single-user systems that can be bought off-the-shelf to
systems, which are developed specifically for departments.
(a) Environment 1 - conventional DP systems.
(b) Environment 2 - one-off PC applications.

(c) Environment 3 - large end-user projects in which several people are going to use a
system, some of whom might be outside the sponsoring department - the development
would still be done by the end users themselves.
(d) Environment 4 - large end-user projects which have to be delegated to computer
specialists to develop.
(e) Environment 5 - departmental systems.
All this does, however, involve the development of systems specifically for end-users.
Remember that end-users must be involved, through participative design, in any systems in
environments one or five.
(a) Safeway introduced a tool whereby a registered customer could record on a personal recorder each
item that they put into their trolley. This record could be used to advise the customer of their bill to
date and of related special offers and it could be used at the check-out to eliminate the need to scan
each item in the trolley, thus saving a lot of time. Both the store and the customer benefited. Because
the customer was registered the output from the tool showed the customer’s individual purchases each
visit. The store could note the purchases made every week and pre-package those before the customer
visited. This would create customer loyalty. Note that this was not Web dependent.
(b) British Airways sees each individual customer as his/her own segment. The aim is then to package a
product for each individual customer. One way is to maintain a database of customer preferences and
use those preferences to tailor price/facilities to what the customer wants. For example, instead of
offering a range of tickets for a journey, BA will ask a customer what he wants to pay and will then
offer a type of ticket that they think will be attractive to the proposed purchaser.
10.9 Summary
An IS Manager is required to supervise three key functions, the development of strategy (both
company and IT), support for the end-user and the running of the IT (or DP) department. Strategy.
Although extremely important it is a subject about which very little has been written.
In the 1960s computers worked only in batch. They occupied a large room in the head office of a
major company and worked on corporate applications. The only contact which the end-user had with
the computer was the requirement to complete a data preparation document and forward this to the DP
department. Of course they then had to sort out the erroneous output from the DP department. In the
1970s on-line systems were developed. These sought data input from end-users (on dumb terminals)
but did not allow the end-user to do anything other than was allowed by the system design. The end-
user had gained some control, however. They now had the ability to render a system unworkable in
some cases. Hence it was essential to involve the end-user in the system design process. In the 1980s
the PC came along. This now allowed the end-user a further sanction. The end-user could purchase an
individual computer and develop an independent system or the end-user could demand an intelligent
front end to a central system. Alternatively the end-user could resist the introduction of central
systems by local disingenuity (for example if the central management wished to introduce a corporate
approach to and standard for office automation this could be blocked). This enhanced user control has
led to the gathering momentum of the client/server approach.

UNIT II
Lesson 11 - Office Automation
Learning Objectives
1. To understand the need and importance of Office Automation Systems

2. To understand the benefits of Paperless Office
3. To know about the components of Office Automation
4. To study the concept of Office Information Systems
11.1 Introduction
The automation of everyday office tasks is one of the key results of the electronic revolution.
Word processors, spreadsheets, databases, accounting packages, networks, and e-mail are but some of
the innovations that have transformed the way we work in the late twentieth century. Integrated into a
smoothly working business system, office automation tools can vastly improve office productivity.
Indeed, no modern office can hope to survive without many of them.
Yet the very richness and diversity of these tools is the source of some of our most serious
office problems. With tens of thousands of programs running on dozens of different kinds of
computers and operating systems, often linked together by a variety of networks, the potential for
incompatibilities is great.
Without doubt, the major change in the office scene over the past few decades is the
introduction of Information Technology.
Up to the late seventies companies used computers mostly or solely for accounts.
Computerization was very costly and meant that only certain key operations could make use of the
technology cost effectively.
Now that desktop computers are available at competitive prices (earlier computers consisted
of costly and bulky mainframes) installing computers has become cost effective, and in most cases
computerisation is seen as a way of reducing operational costs in the long run.
11.2 Defining office automation
Office automation means the complete integration of -

• word processing
• electronic filing
• diary management
• communications, including electronic mail, telex and fax
These functions are the basic requirements of any office or department within an organisation.
Office automation aims to organise the functions in such a way that they do not have to be carried out
on a variety of equipment.
What are the effects of office automation?

• Office automation reduces the number of clerical workers carrying out routine tasks
• Large firms no longer have to employ typists
• Office employees become more flexible and as a result one person can now do the jobs of
several people
• Receptionists can spend more time with clients
• Managers need not necessarily delegate typing, with the secretary's role being redefined
to include more Public Relations work.
What is the latest development in office automation?

The latest development is that of electronic mail. Electronic mail has been around for a
number of years now, but has become increasingly useful as more and more people have a regularly
checked e-mail account.
Will information technology lead to a paperless office?
This is a moot point - some consider the paperless office a myth, others a reality! It depends
more or less on the organisation in question. What is certain however is that at this stage of
computerisation the ease of using a word processor is leading offices to produce an even larger
amount of paperwork - most employees and clients still prefer a hard copy of a document rather than
an electronic one! It is a question of a change in mentality coupled with the approval by the business
community that electronic commerce is viable and is the way forward.
Background Information
Let us see the components and other tools available in office automation in the following paragraphs.
• Function - An action or operation performed electronically by activating a function key
or sequence of keys. Examples of functions include copy, delete, move, search, calculate,
go to, change font, and print.
• Software Package - A program of instructions that interacts with the system's hardware
to perform operational or functional tasks. Software packages are comprised of program
instructions that are applicable to a specific office requirement such as producing textual
documents, developing spreadsheets, establishing databases, or presenting information in
graphic form.
• Software Type - Software packages that provide similar capabilities are categorized as a
particular type of software, e.g., database management, electronic spreadsheet, or word
processing. This guide also refers to some of the more commonly used types of software
described in the sections that follow.
• Word Processing - Word processing software, designed for developing textual
documents, permits users to create, format, modify, and print documents electronically.
With word processing software, an employee can perform such functions as: add, copy,
correct, delete, or move text; automatically print document identification or other
notations at the top or bottom of each page; automatically number pages; create form
letters and automatically merge these with mailing lists; check documents for spelling
errors; designate some characters as boldfaced or underlined or italic; and search for and
change specific text within a document.
• Electronic Spreadsheet - Spreadsheet software, used extensively for accounting and
financial purposes, is designed for maintaining, manipulating, and calculating numerical
data. A typical electronic spreadsheet consists of a matrix of rows and columns similar to
the conventional columnar pad. The user can add, delete, or modify the numerical records
maintained in these spreadsheets. Spreadsheet software provides formulas, functions, and
commands to manipulate or calculate the data to meet multiple report formats.
• Database Management - Database management software provides capability for
organized electronic storage of information in general categories or files. It allows the
user to rearrange the order and number of items of information in printed form, and to
search for and display specific items of information.
• Desk-Top Publishing - Desk-top publishing software is used to lay out text, graphics,
and pictures on a page. With desk-top publishing software, the user can perform such
tasks as: integrating text and graphics on a page; increasing or decreasing the size of
charts, graphs, or pictures and using multiple styles and sizes of type.
• The distinction between desk-top publishing software and word processing software is
diminishing as the latter software packages take on greater capabilities.
• Graphics - Graphics software typically allows the creation of charts and graphs based on
data provided through a spreadsheet or by the user directly. Some graphics software

allows the user to easily switch from one form of presentation to another for different
uses. For example, a given set of budget figures might be represented as a bar chart,
stacked bar chart, line chart, or pie chart. Most graphics software also allows the creation
or selection and placement of pictures and symbols.
• Project Management - Project management software permits the user to identify tasks,
task relationships, resources, and time requirements of a project; to manipulate that
information for planning purposes; to track work progress against the plans; and to report
and display information about the project in varied ways. The software automatically
adjusts such information as starting, ending, and milestone dates for the project based on
changes in assumptions and estimates introduced by the user.
• Calendar - Calendar software generally permits the user to schedule events on one or
more calendars. Additional functions may include capabilities for such purposes as "to
do" lists, short notes and reminders, and recording time spent on various projects.
• Electronic Mail - Electronic mail (email) permits sending information to users through
their computers' communication links. For example, memos can be sent to those on
designated distribution lists, and the recipients can acknowledge receipt, print copies, and
respond through the electronic mail system.
.
Now let us see some of the examples of Office Automation Systems developed in some
organisations.
1. Document Management Contract Tracking Database (Semi-conductor Manufacturing Firm)
Here, they managed the development, implementation and maintenance of an application that
kept track of supplier contracts. The application was developed using Lotus Domino, thus
making accessible via web browsers. The application is used within the company’s Intranet
and users subscribe to the system via on-line registration. User authentication security is used
allowing the application to be used nation-wide.
2. Office Automation Bar-code Software Library (Consulting Company)
In this company they managed the development of a system that kept track of software by the
use of bar codes. The system keeps track of checked software, manages the number of
licenses installed and sends e-mail notifications to remind users of overdue items. The system
won a finalist award in the Lotus Partners Beacon Awards in 1996 for the "Best of Show"
application.
3. Art Management (Food Company)
Gather requirements, developed functional specifications, co-developed & managed the
development & implementation of a web-browser-access based system for a large food
manufacturing company. The application connected to several tables in an Oracle database by
the use of Notes Pump. Both batch and real time access to the data was provided through a
Domino server. Workflow, E-mail notification and document management was used
throughout the system.
4. Restaurant Audit Management System (Restaurant Chain)
This system was developed to automate the collection of quarterly Audit Information for a
national restaurant chain. The system also will calculate the performance of each restaurant
based on the audit evaluation and the weight that each question has. Using this system the
Regional Managers, Vice-presidents and the President will have the results of the evaluation
in short time and have a visual instrument to compare performance of each restaurant in any
of the specific audit section. System was based upon Lotus Notes.
11.3 Office Information Systems
Office Automation is the attempt to use new technology to improve a working environment.
But the remaining concern is how to determine what type of automation tools, if any, an office needs.
To determine which technologies may benefit an office, a careful examination of the
environment is required. There are two main perspectives that can be used: analytical and interpretist.

The analytical perspective has 3 views: office activities, office semantics and office functions. The
interpretist office has four views: work role, decision taking, transactional and language.
Analyzing an Office
It is important to understand an office environment before technology can be successfully applied.

However, a complete analysis can never be achieved due to the complexity of the multiple dimensions
which must be examined:
a. Geographical - the physical placement of the office
b. Temporal - hours of work
c. Activity - tasks that are performed
d. Structural - worker management relations
e. Spatial - area where people work in relation to co-workers
f. Economic - criteria that drive an organization
g. Social - reasons why people become motivated to produce results
Analyzing an office is not only difficult, but also continuous, for as new technologies are introduced,
the affects always need to be measured.
Designing Office Systems
Many efforts have been made to develop office programming languages that can express and
even automate procedures found in semi- structured offices. A formal methodology for assessing
needs and defining office procedures is necessary when using these programming tools.
A methodology to assess needs in individual offices must include these three parts:
• Needs Assessment Methodology
• Procedural Design Methodology
• Procedural Implementation Methodology
A Needs Assessment Methodology is necessary to identify the crucial needs to be served by
automation. If the tools are procedural, then a Procedural Design Methodology and a Procedural
Implementation Methodology should be implemented.
Procedural tools are those in which there is a predetermined flow of work involving many steps. The
flow may be the same every time, or may include a more complex logic flow. With non-procedural
tools, one can specify a set of functions to be supported but cannot say what functions will be used or
in what order. The use of decision support systems, database management systems, electronic
spreadsheet systems, the telephone, and word processing tools generally fall into this category.
Offices can be grouped into two types:
• Type 1 offices or departments handle the firms routine information processing. (For example,
accounting, payroll, and billing departments) procedures are central in these departments, and
the automation of procedures is critical to improved performance.
• Type 2 offices or departments handle the firms non-routine information processing. (For
example, corporate planning departments, marketing departments, and engineering
departments). There are comparatively few set procedures in these departments, and support
of these procedures is not central to improved functional performance. Work should be
supported with non-procedural tools, such as e-mail, decision- support systems, and access to
departmental and corporate databases.
Type 2 offices present a major problem to designers of office methodologies. Traditional procedural
analysis tools are not likely to be effective in determining the needs of the office. Rather, the
strategies that must be designed and supported are likely to depend heavily on the professional content
of the work being done.
Goals of Office Information Systems (OIS) Methodologies

1. The first goal of an OIS methodology is to obtain an accurate description of the
office. A complete and formal description of all aspects of the office work is not
feasible. But, the model used in a methodology should describe as many aspects of

the office as possible in an clear and concise way. This description will be useful to
the system designer, as well as the potential users of the new system by enabling them
to validate the system and suggest possible modifications.
2. A second goal is to locate the functions that are only loosely related to the goals of
the company. This is done to separate these functions into two groups: The first group
includes functions that are not related to actual office work, but are still necessary for
social and organizational reasons; the second groups of functions are those that need
to be re-examined. These functions may be obsolete and are only being done out of
habit. They should be corrected before the implementation of the new system.
3. The final goal of a conceptual model it that it act as a guide in providing technical
solutions, and provide criteria to follow in evaluating possible solutions and in
choosing tools for design.
Approaches to OIS Conceptual Design
A crucial element of a methodology is the type of office conceptual view that is adopted
during the analysis of the office. Different conceptual views will lead to different approaches in the
analysis of office work, and should be considered.
• A technical view examines office work in great detail, by looking at the operations that
are performed and measuring them, usually in terms of execution time. The goal of this
type of approach is to identify the best methods to perform the work. Productivity is
measured mainly in terms of throughputs, instead of considering global office
performance.
• In an organizational view, the global organizational structure of the office is analyzed
and business goals are examined. The (hierarcichal) organizational structure of the
company is reflected in this type of office model.
• A socio-technical view considers the office in terms of tasks to be performed by each unit
of the enterprise. Each unit has some type of control on the work, and has resources and
memory on which to base present and future decisions. A set of rules is used to perform
controls and to take into consideration goals and constraints in the execution of the tasks.
Aspects of OIS
• Office data: The conceptual models on which OIS design is based must be able to
consider all office elements. The data used in conventional Information systems, such as
character, string, and numeric data, are not enough. Other types of data, consisting of
unstructured data contained in messages, mail, and oral communications must also be
supported.
• Time factor: There must be support for scheduling activities, calendar functions, and
control operations.
• Office activities: OIS must be flexible. Office tasks can be performed in several ways,
and instructions for the completion of a task can differ.
• Interconnection of elements: Office activities can be very complex. There are a large
number of elements in each office which are related through several connections. In
general, the elements of office work are distributed amoung several office workers, thus
communication among workers and with the external world is an important function.
• Office evolution: Activities can change over time, and ways of processing information
grow and change.
• Usage characteristics: OIS are highly interactive, and the interface with the users should
be adequate to the type of work to be performed.
• Filtering: Filtering of large amounts of data is required to provide workers with specific
information, related to thier task.
• Reminding: In traditional offices, the arrangement of papers, books, and notes have the
function of reminding workers of activities to be performed and their different priorities.
Information is hidden from the user in an automated office, so the system must provide
the function of reminding, and possibly the scheduling of activities.
• Integration of functions: A number of functions are performed in an office. These
functions such as communication, data processing, information manipulation and

retrieval, and task management may be integrated together and used by the same worker
in fast sequence (or interleaved together). The system must provide easy transitions
between functions.
• Impact of technology Methodologies should be as independent as possible of
implementation details. This is done so that the impact of technology does not effect the
office methodology.
Categories of Office Conceptual Models
Office conceptual models can be classified into categories based on the fundamental elements that
they take into consideration.
• Data-based models group data into forms, which are similar to paper forms in the
traditional office. Types of data and the operations of data are the basic elements of these
conceptual models. Office activities are then seen as a series of operations on data. The
main purpose of data-based models is to represent the office from the viewpoint of
objects manipulated by office workers, in a way similar to traditional offices, where work
was primarily based on documents.
• Process-based models analyze and describe office work by looking at different activities
performed concurrently by the users and the system. The OAM methodology is based on
a process-based conceptual model. The goal of process-based models is that of
representing office activities in a coordinated way. The approach is founded on an
integrated vision of all the activities performed in an office, rather that operations
performed by single users as in a data-based model.
• Agent-based models are based on the viewpoint of the functions performed by active
elements of the office environment, which are the agents. This type of model describes
the office by associating a set of functions to the different agents. The description of the
office is not only dependent on data and processes, but also the set of office workers and
their organizational structure. Its goal is that of examining office workers roles, the
delegation of roles in the office, and so on; while data and activities are considered only
in relation to their executors.
• Mixed models explicitly assume more than one type of element as the basis for system
specification, and go on to define the relationships among these elements. One example of
a mixed model classifies office elements into three sub-models. One sub-model
specifying the data related to the office, the second specifying the operations and
activities in the office, and the third sub-model specifying both the normal evolution of
office work, and the possible structural modifications of office tasks. When compared to
the other models, the mixed model provides a more complete specification of different
types of the fundamental elements in the office.
Office Analysis Methodology (OAM)
This methodology is based on the analysis of the activities performed in the organization. It
focuses on the first two phases of OIS design: The Requirements Analysis phase, and Requirements
Specifications phase.
The goal of OAM is to understand office work in terms of functions, activities, flows, tasks,
and so on. The office analysis process investigates why functions are performed, what they do, and
how they are implemented. The methodology is directed to the analysis of semi-structured problems
at a managerial level in order to identify the business goals of the organization.
Office functions are examined top-down; the office manager and planner are interviewed first,
and then office activities are examined in greater detail, following the office hierarchy. In contrast, the
integration of the office system with the organization and the other systems is performed bottom-up.
The results of the requirements analysis phase are specified in a high-level and problem-oriented
language called Office Specification Language (OSL). This description is implementation
independent, emphasizing office functions rather than specific operational tasks.
o Here is the general schema of OAM:
• Meet with the office manager

o Organizational context and reporting relationships

o Functions and resources of the office
o Identification of conceptual objects and procedures
o Identification of key personnel
• Produce initial procedure descriptions
o Conceptual objects
o Core procedure steps and major alternate control paths
o Inputs and outputs
o Databases
o Environment and special equipment
• Develop and analyze a draft description
o Examine for inconsistency and incompleteness
o Construct list of exception possibilities
• Iterate the interview process
o Circulate draft description
o Resolve conflicts and ambiguities
o Investigate exception-handling procedures
o Watch for ad hoc decision making
• Review the analysis with the manager
o Validate intentions behind each procedure
o Clarify what happens at interfaces with other offices
o General exception handling
• Finalize the office description
11.5 Summary
Without doubt, the major change in the office scene over the past few decades is the
introduction of Information Technology. Up to the late seventies, companies used computers mostly
or solely for accounts. Computerisation was very costly and meant that only certain key operations
could make use of the technology cost effectively. Now that desktop computers are available at
competitive prices (earlier computers consisted of costly and bulky mainframes) installing computers
has become cost effective, and in most cases computerisation is seen as a way of reducing operational
costs in the long run.
The following are considered as the effects of Office Automation
• Office automation reduces the number of clerical workers carrying out routine tasks
• Large firms no longer have to employ typists
• Office employees become more flexible and as a result one person can now do the jobs
of several people
• Receptionists can spend more time with clients
• Managers need not necessarily delegate typing, with the secretary's role being redefined
to include more Public Relations work.
• The latest development is that of electronic mail. Electronic mail has been around for a
number of years now, but has become increasingly useful as more and more people have
a regularly checked e-mail account.
This is a moot point - some consider the paperless office a myth, others a reality! It depends
more or less on the organisation in question. What is certain however is that at this stage of
computerisation the ease of using a word processor is leading offices to produce an even larger
amount of paperwork - most employees and clients still prefer a hard copy of a document rather than
an electronic one! It is a question of a change in mentality coupled with the approval by the business
community that electronic commerce is viable and is the way forward.

UNIT II
Lesson 12 – Tutorial on Applications of Office Automation
PAPERLESS OFFICE
Some years ago, the idea of the 'paperless office' was popularized as
an ideal. We are all familiar with 'paperwork' — such as filling out
seemingly useless or unnecessarily complicated forms. Electronic
alternatives such as computers seemed to offer the promise of getting
a machine to do this busywork. By banishing the paper, we could
avoid the hassle.
There is no question that electronic data management can be used

to reduce administrative burdens. However, paper doesn't cause paperwork, organizations do, and
they are still quite with us. Because organizations can process electronic forms more easily than paper
ones, it may be that so-called ‘paperwork’ will even increase in the future, with most of it done on-
line. It was never fair to blame the paper, so while we reduce paper use, we should not go overboard
and try to avoid paper in those cases where it is the best tool for the job.
Paper is far too useful and satisfying to want to get rid of it. Even if we tried, we wouldn’t
be successful. A "Paperless Office" makes about as much sense as a "glassless office" or a "metalless
office".
The ‘paper efficiency’ approach acknowledges the usefulness of paper, but recognizes that
we can still use considerably less than we do now. The "Paperless Office" is like a starvation fast
that just won't last. By contrast, "Paper Efficiency" is like a balanced diet with good physical exercise.
Q: What are the considerations, technologies and steps I should take to make our business
paperless?
A: I take it that your business is buried in paper. That's no surprise. You've just hit on one of the most
common complaints among both office workers and business owners.
Twenty years ago, the PC was introduced as a tool that would virtually eliminate the paper then
choking the average office. But that hasn't happened. In fact, market analysts report that paper use
continues to boom—by an incredible 6 to 7 percent annually.
It's no small issue. Hard-copy costs typically eat up 1 to 3 percent of a company's revenue.
Meanwhile, worker productivity sinks, as knowledge workers spend 10 or more hours per week just
sifting through paperwork. First the bad news: For the foreseeable future, paper is here to stay. But
don't be too discouraged. Through information technology, this glut of paper can be held in check.
Best of Both Worlds
Eliminating paper in business certainly is a desirable goal. But, unfortunately, it's not
currently realistic, since paper plays important psychological, aesthetic and legal functions in today's
business world. Hard copies continue to have many advantages over electronic documents, including
better reader comprehension, less eyestrain, greater mobility, superior flexibility and an enhanced

comfort level among workers. In addition, U.S. states and foreign countries vary considerably with
regard to the legality of electronic documents and signatures.
For the time being, therefore, it's best to combine some use of paper alongside electronic or digital
information systems. This approach can substantially reduce, although certainly not eradicate, the
reliance on paper in your office. Some of the most effective paper-busting technologies include:
• Computers: PCs, laptops and handhelds can be combined for document creation mobility
and flexibility, stamping out rampant paper use.
• Scanners: Scanners create digital images so that documents can be exchanged electronically
and preserved easily. When scanning, remember to employ image compression to maintain
network performance, and make sure to choose a single, standardized electronic document
format so that images can be indexed and searched easily.
• E-mail: E-mail is a great substitute for paper memos. Effective e-mail systems should allow
users to filter content and file messages electronically by topic. They also should let workers
combine e-mail with fax and voice-mail retrieval in a unified messaging system.
• Storage systems: Affordable, robust storage technology is essential for high-speed,
centralized electronic information management. Check out low-cost systems built upon RAID
(Redundant Array of Independent Disks) technology or iSCSI-based storage-area networks.
• Fax over IP (Internet protocol): The boring old fax goes high-tech with a Web- or e-mail-
based fax capability that eliminates the need to send hard copies.
• Wireless local area networks: Wi-Fi LANs are spreading like wildfire, making electronic
information mobile, portable and easily accessible to workers anywhere.
• Secure remote access: Virtual private networks (VPNs) ensure that home workers and road
warriors get secure, confidential access to the company intranet, abolishing the need to lug
around a briefcase full of documents.
• E-learning systems: Workers in training can say good-bye to books and binders when they
use online or Web-based training systems.
• Advanced printers: Printers that print on both sides of a sheet can significantly reduce paper
use.
Naturally, each company's needs vary. So companies are advised to take the following steps:
Assess current paper usage, determine which electronic systems are most useful, get familiar with and
read reviews of available products, and get the best price. To cut paper use most reliably,
organizations also should devote resources to training employees on the new technologies and have a
method in place to measure return on investment.
So be heartened. There are numerous ways to substantially slash the use of paper, while striving for
the ultimate goal of a completely paperless office.

13.1 Introduction
We are in the world of advanced Information Technology where things are moving in such a fast
phase. The availability of information becomes cheaper and faster and the facilities existing to
exchange the information among users all across the world has become more simpler due to the
evolving of Information Super Highway. The internet provides fast and inexpensive communication
channels that range from messages posted on bulletin boards to complex exchanges among many
organisations. It also includes information transfer (among computers) and information processing. E-
mail, chat groups, and newsgroups are examples of major communication media. Let us see the major
components of Electronic Communication System as follows.
13.2 Electronic Conferencing
Professionals in all fields are looking to Internet technology to find communication methods
that encourage greater collaboration and are an efficient way of dispersing helpful and relevant
information in a cost effective manner. One method that has become increasingly popular is
conferencing, whether it be on “electronic bulletin
Boards”, listservs, in chat rooms or using web-based meeting protocols.
Conferencing allows a large group to exchange ideas by reading and posting messages which
are delivered to a central point and broadcast to the conference participants by special software. This
is done in a synchronous or asynchronous mode, that is when all participants gather together at the
same time or not! i.e. that conference participants can read and post messages at any time.
Conferencing has its advantages and disadvantages. By far, it is cheaper than using long-
distance telephone or fax and the software and hardware needed to run it, a personal computer and an
Internet connection, are becoming so readily available that it makes it possible for larger numbers of
people to become participants. Conferencing keeps meeting costs down because the costs associated
with face-to-face meetings such as travel and accommodations don’t exist. And in most modes of
Internet conferencing, subscribers can participate at a time that is convenient for them, thus helping in
the old “time management” dilemma.
Some people find it difficult to commit the amount of time it takes to make conferencing
successful, and others don’t like it because of the lack of personal contact. Participation is linked to a
person’s previous experience with technology and the Internet, his likes and dislikes or her preferred
learning styles. Research suggests that auditory learners may feel distanced from discussions in
asynchronous conferences and may prefer telephone or face-to-face meetings where they can be
heard. Visual learners usually flourish in the on-line environment because they are used to processing
large amounts of information in this manner.
Kindhearted learners miss the body language and immediate feedback of personal meetings.
Electronic meetings will have about the same number of non-participating members (in this

environment called lurkers) as do regular meetings. I have been using computers since the mid-1980s
and love the immediacy and speed of electronic communication and the sense of virtual equality it
provides. Over the years I have participated in many online conferences. Through the process of trial
and error some ideas on how to encourage more participation in electronic conferences have emerged.
These suggestions are from a committed amateur!
• Pre-planning: Decide on a series of topics and find guest facilitators/moderators who will
lead the discussion on a given topic. Determine how long a conference will last--a day, a
week, several weeks, a month etc. Spread the dates of the conferences out over a six or eight
month period with a good break between conferences (three conferences in this time period
would be good). Promote the conferences in advance. This allows people to begin thinking
about the topics and the kinds of questions they would like to ask or information they would
like to share.
• Promotion: Begin sending messages introducing the moderator, giving information about the
participants and commenting on different elements of the topic to conference subscribers two
weeks before the conference to build anticipation.
• Introductions: Ask the guest moderator to introduce him/herself a week or so before the
actual start of the conference. During that time, ask the moderator to post the conference
agenda and request potential participants to: a) introduce themselves, b) suggest what they'd
like to learn from the conference, and c) identify one or two of their favourite resources
related to the topic. These are ways to “break the ice” that can contribute to the quality of the
conference and, unobtrusively, help the participants feel more comfortable as they get to
know and feel at ease with each other and this, for some of them, new manner of meeting.
• Time Factor: Consider stretching the conference out over an appropriate period of time and
have the moderator post her/his “conference” material every third day or so, depending on the
over all length of the conference, to give participants more time to come and go on the
system. Adjust this as time goes on, as participants become more comfortable with this
process in general and become more active in their participation.
• Be Prepared: There will be lulls in the action: at the beginning, as people are waiting to see
how this will develop and at various points during the conference when interest may seem to
be waning. Consider preparing a few colleagues to encourage discussion by having them
ready to respond to the moderator’s postings, ask questions or post their own ideas at times
when the action needs to get started or participation is slow.
• Evaluation: Have a routine “post mortem” after each conference where participants, by way
of an evaluation, can suggest what learnings they may glean and what could have been done
to make the conference more helpful, specifically for them.
• Technical: Electronic conferences should be held in a venue separate from the one people use
for normal discussions. This way, regular users are less likely to feel they are interfering with
or interrupting the conference. Electronic conferencing can be enjoyable as well as efficient
and convenient. Giving some thought to how the conference will progress before it even starts
will help to make it a valuable and enjoyable experience for all.
The most basic form of e-conferencing is what we call "Sync" or synchronous mode. It
involves having everyone on-line at the same time like a face-to-face meeting or teleconference. We
use a mode called Internet Relay Chat (IRC, or "chat") to all talk together in a common "room" or
"channel". Control is kept by following some simple but critically important rules:
• Everyone follows the lead of a facilitator, who controls the flow of the discussion.
• Only one person has the "floor" at a time - that person is determined by the facilitator
• You raise your hand to speak by typing a "C" for comment or "Q" for question, then pressing
"enter"
• The facilitator will call on you when it is your turn by sending "GA" (for go ahead), followed
by your name.
• When you are "talking" by typing your comments or questions, remember that the others
cannot see what you are typing until you press "enter." You can break up a comment or

question that takes more than one line by typing "…" at the end of a line, pressing enter, and
starting a new line. Three dots at the end of a line tells everyone that you are still "speaking"
and you will not be interrupted. "C" or "Q" may be sent by someone during this time, but
those people will not get to state their comment or question until you have finished. The end
of your last line of your turn should have a period, question mark, or exclamation point
(whichever is appropriate) to cue the facilitator that you are finished. If you do not put any
punctuation at the end of a line, it may not be clear to the facilitator and other participants
whether you are finished or not, and the meeting can be delayed while they determine that
fact.
There are some basic overall rules that also must be followed for the meeting to be successful.
These are:
• An agenda must be developed and posted before the meeting. This is usually done by the
facilitator, working with the "sponsor", or leader of the group that is meeting. In most cases,
the sponsor should not be the facilitator of the meeting. The facilitator should not have a
personal stake in the meeting so they can be as impartial as possible.
• All reports must be submitted before the meeting and posted or mailed so that everyone can
read it before the meeting. Reports may not be "read" to the group at the time of the meeting,
as this takes far too long and is just poor meeting practice!
• The meeting must start on time. It is even harder to sit staring at a computer screen than it is
to sit in a meeting room with other people around when key people are late.
• Off-topic discussions and "sidebars" (one-on-one conversations) in the meeting "room" will
not be tolerated during the meeting. You can have a sidebar conversation with someone by
double-clicking on their name in the chat program. This is a totally private talk and does not
disturb anyone else. The advantage of this technology is that you can hold this conversation in
one window while staying in the regular meeting in another window on your computer screen.
Although not recommended for your first few meetings, it is possible to hold numerous
conversations and even meetings of subcommittees, etc while the main meeting is on. Just be
sure that these distractions do not adversely affect the main meeting! You should also exercise
caution by carefully noting in which window you are typing before pressing enter.
13. 3 Electronic Meeting Systems
Meetings are a way of life in every business. Meetings can be a source of tremendous
frustration. Meetings are also costly: put six people in a weekly staff meeting, and you've eaten up
$10,000 worth of time. Total quality management, business process re-engineering, team
management, and other techniques of the 90's aren't helping---most of these techniques actually
increase the number of meetings people attend. Because meetings are so expensive and so inefficient
and so dissatisfying, it's no surprise that there are lots of software developers working on tools to
improve meetings.
These tools span a wide range of meeting assistance and support tasks. At the low end,
software schedulers keep track of people, appointments, and resources to coordinate meeting times
and places. In the middle are tools which help groups by improving communications. This includes
conferencing systems and bulletin board packages, which extend "meeting space" outside of the
meeting room by letting participants discuss issues without having to sit together. Other mid-range
tools are designed to assist communications during a meeting. Video and audio conferencing
hardware can be integrated with personal computers to link people in diverse locations for a single
meeting. Shared drawing and editing tools also help groups work on a single document or share a
visual concept easily.

At the high end are systems with much loftier goals: the complete reinvention of the meeting
process. Developers of these systems have developed ways of completely changing the way meetings
are held, and they have numbers from customers proving massive and dramatic improvements in
productivity. But these benefits come at a cost---attendees must stop thinking of meetings as a waste
of time and start thinking of meetings as an opportunity to make decisions and share information.
Schedulers to Keep You on Track
The low end of the meeting support market focuses mainly on scheduling meetings and
managing calendars. Although there are many products available for standalone use or which support
only a single platform, only a few vendors have taken an enterprise-wide approach to scheduling.
Even so, any organization with truly disparate platforms will find it impossible to find a vendor
willing to support all popular platforms for this relatively simple task.
In evaluating group scheduling systems, network managers must keep in mind the underlying
politics of scheduling. These are generally more important to the success of a group scheduler than
quality of user interface or performance. If the group scheduler cannot successfully emulate people’s
behavior regarding their own personal calendar, then it will not be accepted into the workplace.
Groupware of this type must fit into the organization; it is not reasonable to expect people to change
the way they operate simply to accommodate an appointment-scheduling program.
Spreading the Meeting Room Around
Traditional meetings are same-time, same-place activities everyone has to be in the same
room at the same time. Software and hardware, which extends the meeting room across both time and
space, can substitute for some face-to-face meetings, empower people in remote locations, and
improve face-to-face, meetings by making everyone better prepared.
The oldest alternative to face-to-face meetings is computer conferencing systems

(sometimes called bulletin boards, although purists make a distinction between the two). These
conferencing systems grew out of multi-user systems and often: support both microcomputer and
dumb terminal interfaces.
Most conferencing systems do little more than let people exchange information and follow a
single message and its associated discussion. The largest multi-platform conferencing system of this
type is the Usenet News system. With literally dozens of public-domain and commercial "news
readers," and a good selection of minicomputer-based servers, a simple conferencing system can truly
encompass all corporate computing platforms, including dumb terminals, all microcomputer systems,
on up to window system terminals. Other commercial products which support multiple platforms
include Digital's (800/DIGITAL) DEC Notes, Lotus' (800/522-6752) Notes, and Pacer Software's
(800/722-3702) PacerForum.
Lotus Notes is one of the few products which can be extended to include additional group
conferencing facilities, such as voting on issues, surveys, and anonymity. Conferencing systems with
these facilities built-in are found in research projects more than commercial products, such as the New
Jersey Institute of Technologys EIES (Electronic Information Exchange System) conferencing
system.
The computer-equivalent of an audio-conference or video-conference is also available.

Although some tools aim to replace face-to-face meetings with group type-fests, only certain narrowly
defined meetings will benefit from these tools. Because typing is so slow compared with talking, a
traditional audio or video conference is much more cost-effective than asking meeting participants to
type Gin their comments and thoughts rather than simply speaking them. The Meeting Room does

replace face-to-face meetings, but supplements them with audio-conferencing capabilities, either
through a PC-based software/hardware combination or via a normal audio conference.
Group editing and drawing tools fill a different niche. These are meant to supplement face-to-
face meetings or audio conferences by letting participants share a single view of a document or a
picture. Aspects is a Mac-only version of this which lets networked systems share in the tasks of
editing documents and pictures. Their Mac and Windows product, Whiteboard, gives cross-platform
compatibility at a price---only shared drawings are supported.
Making Meetings Better
Let me explain how to make the meetings better with a product called GroupSystems. It isn’t
a single package. It's actually a suite of software tools (sixteen in the DOS version, fewer in the
Windows version) which automate and enhance many of the processes which occur in meetings. A
meeting using GroupSystems requires a personal computer for each participant and a "facilitator,"
someone to lead the meeting and choose which GroupSystems tool is most appropriate to the task at
hand.
For example, suppose you want to have a meeting to help decide on a new name for your
company. In the GroupSystems world, the meeting would look like this. First, participants in the
meeting would brainstorm ideas using the Electronic Brainstorming tool. Each participant would enter
as many ideas as they could think of during a defined time period, say 10 minutes. As ideas were
typed in, GroupSystems would shuffle them around and send them to other participants. By seeing the
ideas of others, presumably, you come up with your own possibilities.
GroupSystems advocates claim two advantages over manual meetings: participants can type
in more ideas more quickly than anyone could possibly write them down because everyone is typing
at the same time. Each idea is evaluated on its own merits, rather than based on who said it. Because
tools like Electronic Brainstorming are anonymous, people who are normally afraid to bring up
opinions in a meeting will be able to bring their best ideas without fear. ? In most professional
meetings, this anonymity is rarely abused.
Once brainstorming was over, the facilitator would use another tool, the Categorizer, to put
ideas into different buckets based on group opinion. Since brainstorming would likely have generated
hundreds of ideas, it would be important to narrow them down into broad categories, such as
"favorites," "maybes," and "disliked." In this phase, normal discussion would prevail---except the
process of sorting the ideas would be assisted by computer.
Finally, participants would be asked to vote on the ideas. GroupSystems supports seven
different kinds of voting. In this example, participants might be asked to rank their top ten favorite
ideas. GroupSystems would tally the anonymous votes present totals on a screen in the front of the
room. Before anyone left the one-hour meeting, the top ten names chosen by the group would
Changing the Face
GroupSystems does not augment existing meetings. When a company buys into, they are
buying much more than a software package. To properly use the system, facilitators must be trained in
maximizing meeting productivity using these tools---because GroupSystems changes the way
companies hold meetings. Bringing in GroupSystems is not a trivial investment. GroupSystems
requires a PC in front of each user, Windows or DOS, a LAN (any popular microcomputer LAN
package will work) to link them together, and a facilitator's station to control the meeting tools.
GroupSystems also uses a shared screen at the front of the room which has to be large enough for
everyone to see. With a base software and training cost of $25,000, building a meeting room for
GroupSystems usually costs about $100,000.

GroupSystems doesnt require a dedicated room. In theory, it's possible to bring together a
bunch of laptop PCs with network cards, stick an LCD panel on an overhead projector, and hold a
GroupSystems-assisted meeting. Most companies, though, decide to allocate a space where
GroupSystems is always available. If anyone can use the meeting room at any time, the reasoning
goes, 1we'll maximize use of the equipment and software.
13.4 Electronic Discussions
We've all heard so much hype about the potential of computer mediated communication to
revolutionize teaching that we've begun to dismiss it automatically. We need to recognize, though,
that it's not all hype. Even once you've discounted the snake oil salesmen selling off-the-shelf
electronic course guides, style checkers and "interactive" computer-assisted learning programs, in fact
there are still some startling opportunities. There are many reasons to expect that computer-mediated
written discussions -- to pick the one that I'm most interested in -- should afford unprecedented
learning opportunities, combining the flexibility and interactive engagement of oral conversation and
the power of written language to foster reflection and allow complex ideas to be accumulated, revised,
extended and polished.
But there haven't been many demonstrations of this potential. Indeed, the most common
consequence of setting up an "electronic discussion group" for a university class or a group of faculty
at an institution, or a set of colleagues with common interests, is a flurry of initial greetings ("Hello,
everyone, isn't it great to have this new way to communicate"), followed by an enduring silence. The
flurry may last somewhat longer for students in class-oriented discussions -- especially if participation
is made a course requirement -- but even in those cases, most often the quality of the participation
quickly becomes perfunctory and unengaged . . . usually not long before the instructor quietly allows
the requirement to lapse.
To think about why this happens, and what we might do to avoid it, it's important to be clear
about what sorts of programs and situations we're talking about. For many people, "it's all e-mail," but
that oversimplification masks some distinctions that are worth making.
There are a number of ways we can group such programs to help us think about the
characteristics of the different kinds of thing we're talking about here. One is to distinguish between
"synchronic" and "asynchronic" types. Synchronic programs work in "real time"; that is, you write,
someone reads immediately, and the text is gone, usually scrolling up the screen to oblivion. These
include structures ranging from Internet or local "chat rooms" to highly developed sites, where
conversations take place in virtual environments which can be fairly richly detailed. On the other
hand, "asynchronous" programs like list servers and bulletin boards tend more toward the status of
written correspondence -- or even publication. Messages persist (for instance, in your incoming mail)
until they're read, and in fact can be easily saved after reading, and responded to at your convenience.
Most programs used in classes other than computer-dedicated writing classes are of this latter kind.
It's important to remember that these categories aren't neat oppositions: programs aren't
simply one or the other. In a synchronic conversation -- as in oral conversations -- it's possible (but
difficult) to go back to something someone said earlier, to re-open a subject, even to save what
someone said (with a tape recorder, for instance) and quote it at a later point. Similarly, there are
synchronic elements involved in email or listserv exchanges -- people can be online simultaneously
while "conversing," making the time lag almost negligible. Further (also as in oral conversation),
beyond a certain temporal point, subjects get passed by and are no longer opened in practice -- in part
because they're difficult to get back to; in part because the interest of the group and the momentum of
the conversation has passed them by.
It should be obvious that one characteristic of all electronic communication is a tendency

toward increased immediacy. It skews discourse, in other words, toward the synchronic. Not since

there were multiple daily mail deliveries in 19th century London has it been possible exchange
extended written communications at a distance more than a time or two a day. This potentially short
time span between utterances is one of the properties of this sort of discourse that we'd expect to
foster continuing, sustained conversation, and the kind of learning we think follows on that kind of
engagement with literacy and ideas. Why it so rarely works that way is the question I want to try to
deal with here.
Another way to categorize electronic discussions is by thinking of them as tending toward

either of two extremes which are often characterized as "push" or "pull" technologies. In a "pull"
technology, you have to do something to access the conversation. In traditional bulletin board
program, for instance, you have to log in to the board and read the current messages (usually the
program tracks your reading and only shows you the ones you haven't already seen). If you don't think
to log in regularly, you drop out of the conversation. It's like having to go to the newsstand to buy
your paper rather than subscribe to it -- with the additional complication that sometimes (perhaps most
of the time) when you go down to the newsstand there's no paper to buy, and so it's pretty easy to get
out of the habit of checking.
At the other extreme, a list server based program (one that redistributes email sent to a central
address to everyone subscribed), is a "push" technology, in that messages come to you, whether you
remember you're subscribed or not. Again, of course, these categories aren't neatly distinguished: you
do have to log on to your system and check your email for those messages to come to you, so it's not
entirely passive. But anyone who regularly uses a networked computer will probably have many
motives for checking her email, so that can be taken as a given, like turning the car radio on. One
would expect that "push" programs would generate more regular participation and contribution than
"pull" ones; again, however, the difference isn't as strong as we might expect.
There are other important distinctions to be made among various ways of mediating electronic
text, but the one with the most important consequences for teaching is one that was first made clear to
me when I began to encounter the increasingly widely used programs based on the World Wide Web,
which in some ways are a dramatically different kettle of fish. These programs use the graphic
capabilities of the Web (especially Hypertext and HTML) to produce interactive sites which combine
the advantages of list servers and bulletin boards, and which can be seen both as push and pull
technologies -- that is, you need to go to the site to post, but there is, or can be, email notification of
postings as they occur, to remind you that there's a discussion in progress. More important, they do
not isolate messages from their context the way the older bulletin board and listserv programs do.
That this was important first came clear to me as I considered that every bulletin board-style
program has a built-in process whereby the program keeps track of which items you have already
read, and does not present them to you again unless you specifically ask for them (and often getting
them is extremely complicated). So, for all practical purposes they're not there, and thus the messages
in front of you at any moment appear to have no past. Even to see the message the one you're reading
is immediately responding to is it pretty difficult (most programs have conventions for including the
text of the message being responded to, but this convention itself poses problems for readers not used
to it). To go further back and see what may have come before the immediate message is, for most
users, simply impossible in practice.
This is equally true for list server programs. If you're saving all messages, it's possible to get
back to them -- but very few users do this habitually, or have time or expertise to sort the saved
message so they're readily accessible. Sometimes lists are "archived" on a Web or FTP site, and can
be searched, but, again, this requires a relatively sophisticated level of computer expertise.
Equally important, the messages have, in one very practical and important way, no future
either. As you're reading a message, you usually can't be sure whether someone else has already
responded to it. Sometimes you'll be able to see a list of subsequent messages, along with their

"subject lines," and be able to infer that one or more of those messages might be later responses to the
one you're reading, but when you move on to check, the target message becomes part of that lost past.
Once you've read the later messages, you can't easily go back to the one you wanted to respond to. If
you're adept with computers, you might have saved it to a file, or printed it out, or moved from one
window to another, but most of us don't do this. What in fact happens is that you don't respond to the
message -- either you find that others have already responded, or that they haven't but you can't get
back to it to hold its text in front of you while you respond. After experiencing this a few times, you
learn that if you're going to respond, you should do it immediately, before trying to look ahead -- so,
in practice, messages on bulletin boards and listserv programs have, in practice, no effective past and
no effective future.
What this means for most users -- and especially for most newer users -- is that they don't, in
practice, look back or forward at all. Thus their attention is focused on the immediate edge of the
wave of discourse creation. And thus either they're dissuaded from entering a conversation (if you'd
only heard -- or could only remember -- the last remark anyone made at a table, you'd be reluctant to
jump into the exchange), or to responding immediately and without much reflection. Thus, often they
find that the conversation tends to be repetitious and superficial. One of the common complaints of
long-standing members of listserv groups is "we've been over that a dozen times," as new members,
with no practical access to the past, join in. Another is, "why do I have to read the same trivial
comment sixteen times, from sixteen different people?"
It is possible at least to imagine a situation in which the context of utterances is immediately

and perceptibly available to the participant in a useful and accessible form, offering more functional
information for planning and shaping the discourse: offering, in fact, what I call "back pressure" that
is very similar to what a conversational dialogic situation offers to the creation of an oral utterance. It
is possible to imagine a program which doesn't insist that you respond now or never, one that fosters
reflect ion, using the power of written language to support extended and engaged discourse. It has
recently become clear that alternatives are not only conceivable but also possible. New ways of
structuring written discussions are appearing, using some of the logic of the traditional programs and
adding new elements made possible by the development of the World Wide Web and the various
"web browser" programs for navigating it. One program I am aware of which demonstrates this
potential is called HyperNews, developed at the University of Illinois and currently available as
freeware. Another is Ceilidh, designed by Richard Hughes in San Diego and also available at nominal
cost (more information on them, and similar programs, is readily available on the Web. If you're
interested, the addresses are listed below).
What such a program offers us, primarily, is a different, and more immediately visual (and
more uniform, from user to user), way of presenting the list of read and unread postings, based on the
cross-platform flexibility and graphic capabilities of the World Wide Web and web browsing
programs. It makes possible a number of activities that older programs for conducting, constructing
and recording text-based discussions don't, and thus addresses these problems -- including the
disappearance of context.
The fundamental trick is this: instead of one message at a time, these programs present the
entire conversation, displayed in outline form, with each message identified by a useful subject line
and hot linked to the full text of the message. The structure of the display is very simple: the messages
-- identified by author and subject line -- are arranged in an outline form hierarchy, with the structure
of the relations among the messages marked by indentations. It might look rather like this:
• First message (A)

Response to message A (B)
Second response to message A (C)
• Response to message C (D)
o Third response to message A (E)

Response to message E (F)

• Response to message F (G)
Second response to message E (H)
One consequence of this, obviously, is that chronology becomes less important and the logic
of he conversation more so. Another less obvious consequence is that the way the relationship is
presented graphically is determined not by what subject lines the writers choose for their message, but
by the actual relationship among them: if you respond to a message, your response will appear below
it, whenever you choose to do so. This means that subject lines themselves can become more
descriptive of the nature of the message. They don't always do so, of course, but the situation allows
the reader to signal things about her message and still preserve its position in the graphic display (on a
newsreader, changing the subject line would cause the message to start an entirely new category of
message, beginning a new chain of message & responses -- if, that is, anyone responded without, in
turn, changing this new subject line).
What is most important about the fact that the program is based on the World Wide Web is
that each message listing is a hot link, meaning that if you click on it, the message it designates
appears immediately onscreen, replacing the outline list of postings. Going "Back" with the web
browser returns you immediately to the outline; "Forward," to the message again. This ease of
navigation back and forth from structure to discourse is an important part of the way such programs
promote keeping participants in touch with the past and the future of each message -- with, that is, the
context of the discussion.
13.5 Electronic messaging
Electronic messaging is more than just text messages passed between human writers and readers -- it
offers a great potential in our environment to automate a great deal of routine data passing as well.
These notes are devoted to exploring the topic to illustrate some of this potential and to helping you
make some wise investments upon which you can grow a flexible, robust capability. Don't let the
growing pains and a seemingly endless supply of warts divert your attention too much.
The first broadening of use of e-mail for more than the accustomed interpersonal communications is
command communications. It is the best replacement for the traditional telegram-style record
message. This is the market that the Defense Message System is targeting.
The second use is in automated systems where at least one end -- either the originator or the recipient
-- is a machine rather than a human. Secure, multipurpose e-mail is an extremely good idea -- and one
whose time came some years ago. Unfortunately, the impediments to a deployed, usable system have
been considerable, and the worst ones largely unforeseen.
On the other hand, this litany of growth pains should really be put into the perspective that e-mail is a
very powerful tool ... that has improved enormously in a fairly short period of time. E-mail should be
the choice of first resort for the enveloping definition for almost any information system. Including
'tactical' ones. If it fits, look no farther.
13.6 Electronic Publishing
Traditional publishing involves four steps. First the authors produce their material for
review by editors working on behalf of publishers. Material found suitable for a publisher is then sent
to be typeset, to format the content into individual pages with a chosen style. These pages are then
reproduced in multiple sets by putting ink on paper, and are bound into individual books and journal

issues. Finally these are distributed to the audience by post to mailing lists of subscribers, book club
members, libraries with standing orders and people who order books on line, or through retail outlets
like bookstores and news agents.
Computers have played certain parts in this process for some time. Authors use word
processors to build up, revise and print the source material, and more complex typesetting software is
used to format pages with humans putting in the required commands to specify type fonts and sizes;
pages sizes and partitions; insertion of figures, equations and footnotes; linking parts from different
sources, such as chapters by multiple authors or reproduction of existing material, into a complete
volume etc.
Most of you would be familiar with MS Word, and some of you may have used Latex,
which formats an ASCII text file with embedded typesetting commands, into a DVI file specifying
the content of each page, and this is further processed using a DVI to printing file (such as PDF or
Postscript) converter which specifies in minute detail what kind of symbol to put onto each page
where. Desktop publishing software basically combines word processing with easy to use typesetting
software so that an author or editor can produce camera ready pages to be sent to a printer on his own
PC, while HTML is a desktop publishing language that specifies the content and format of single
pages for output on a computer screen with provision to add colour, sound, video, etc. The old
equipment that were used to do the job, typewriters, molten lead typesetting machines, even paper
typesetting machines (to produce masters for offset printers) are hardly used these days.
While computers have also played some part in controlling printing machines and in
helping with the mailing and selling of printed material, their impact there has been much less
fundamental, since they have not changed the basic process of putting ink on paper and distributing
the paper piles. This is a highly inefficient process since the paper contributes almost all the weight,
but the information is only carried by the ink. It takes organization to record, store and move around
all that heavy bulk. In fact, one reason authors have to go through publishers to publish is the latter
control the physical distribution system: while authors can produce content and make copies on their
own, they lack means to put the copies into the libraries and retail shops, or to use large mailing lists
to send copies to readers.
The Internet has radically changed this: Content is now specified as modulations of
electromagnetic waves, conducted instantaneously across the world via wires, satellite links and
optical fibres, instead of ink on paper moved around on lorries and aeroplanes. With numerous search
engines crawling the web looking at every page and cateloging the content, it does not take long
before your pages would turn up in a search list of someone looking for related material.
In short, with the help of PC on Internet, anyone can write, format and distribute his
writings in the most direct way. However, while this solves one problem, it creates a new sets of
issues for authors and publishers: Content represented in this way is also easily reproduced, without
any graphical quality loss nor the work of copying, collating and binding. The previous exclusivity of
control is now lost. For commercial publishing, the question is how to get paid when someone reads
something you own. For scholarly publishing, the issue is establishing who published a particular
piece of work at what time.
It is sometimes said that encryption would protect intellectual property rights: the material
is stored on the web in a coded form, which can only be reversed if you know the decoding algorithm.
But this is not really effective, because one can always make copies of the decoded result, whether
text, picture or music, and give them to others, unless the decoding is embedded into the final display
unit so that the user never gets the decoded file itself. However, I can still make copies for other users
provided they have the same embedded decoding system which would work on the same undecoded
files. To prevent this, you have to have several versions of the embedded decoding algorithms, so that
the coded file that works with my system may not work with yours, but then the content provider will
have to know which coded file will work for which user, making his system more complicated.
The idea of digital watermarking has also been suggested: a unique pattern is converted into
a signal that looks like low intensity background noise, which is added to a picture or music file; when
the reverse conversion is applied to the combined signal, the original unique pattern is recovered, so
that if someone has a copy of the file, you can prove that the copy came from you by revealing the
watermark in it. Unfortunately, this too is not a simple situation: I can take anybody's file, and run a
program on it that would add a new watermark, and then claim that he stole the file from me. He will

then have to prove that my program is a fake and is adding rather than revealing the watermark. The
authentication problem is merely transferred to another domain.
Basically, the ownership issue of electronic publishing remains unresolved, but with most
material on the web, the issue does not really arise as the authors/publishers are only too keen to give
the content away, either as a kind of vanity publishing, or in hope of building up an advertising
market so that income is generated in ways other than payments from the readers.
A small number of publications, such as Wall Street Journal, succeed in getting subscribers
to pay annually to register, but expects that some readers will copy and email some of the articles to
people who are willing to wait. The Microsoft online journal Slate tried paid subscriptions, but gave
up after less than a year and reverted to free access. Some authors have tried putting their books on
line a bit at a time asking for voluntary payment and promising to add the next bit after enough money
comes in but this too has not worked out very well for those trying it.
In any case, web publishing for a living remains a doubtful proposition; while printed
material, being directly readable without equipment and hence easily portable, remain an important
means of communication.

Lesson 14 - Introduction to Networks
Learning Objectives

2. To know about the components available in Network
3. To realize the benefits of Networking
4. To study about the issues in Implementation and Maintenance of Networks
14.1 Introduction
Information and communication are two of the most important strategic issues for the success of
every enterprise. While today nearly every organization uses a substantial number of computers and
communication tools (like telephone or fax), they are often still isolated. While managers today are able
to use applications like word processors or spreadsheets, not very many of them use computer-based tools
to communicate with other departments or information retrieval programs. To overcome these obstacles
in an effective usage of information technology, computer networks are necessary. They are a new kind
(one might call it paradigm) of organization of computer systems produced by the need to merge
computers and communications. At the same time they are the means to converge the two areas; the
unnecessary distinction between tools to process and store information and tools to collect and transport
information can disappear. Computer networks can manage to put down the barriers between information
held on several (not only computer) systems. Only with the help of computer networks can a borderless
communication and information environment be built.
Computer networks allow the user to access remote programs and remote databases either of the
same organization or from other enterprises or public sources. Computer networks provide
communication possibilities faster than other facilities. Because of these optimal information and
communication possibilities, computer networks may increase the organizational learning rate, which
many authors declare as the only fundamental advantage in competition.
Besides this major reason why any organization should not fail to have a computer network, there
are other reasons as well:
• cost reduction by sharing hard- and software resources

• high reliability by having multiple sources of supply
• cost reduction by downsizing to microcomputer-based networks instead of using mainframes
• greater flexibility because of possibility to connect devices from various vendors
Because of the importance of this technology, decisions of purchase, structure, and operation of
computer networks cannot be left to technical staff. Management as well has a critical need for
understanding the technology of computer networks.
14.2 Networks: Meaning
A computer network is a connected set of autonomous computers. Normally each computer has
its own operating system, a network operating system. Then the user is aware of the network and the
different computers. In a network operating system a user must explicitly connect to other computers in
order to communicate with them.

Client/server networks are networks that connect individual computers, known as “clients”, and
one or more central computers, called “servers.” There are many types of servers, the most common being
a file server. In a client/server network, the file server acts as a shared resource – a repository for files,
such as documents, spreadsheets, databases, etc. Instead of storing these files on each individual machine,
the file server permits storage on one central computer. In addition to the obvious advantage of reducing
the possibility of multiple iterations of a single file, it allows the organization to have one centralized
point from which to backup its files, as discussed fully below.
A distributed system is also a connected set of computers, but the system hides the existence of
the network and the user is not aware of the different computers. A single system (operating system) runs
on all computers and distributes work etc without the user's knowledge or assistance.
14.3 Network Basics
14.3.1 Standards
Standards play a significant role in the field of computer networks. Special-purpose development
of communications hard- and software must be avoided because of its high costs and the need to
interconnect devices from various vendors. Therefore some kind of international conventions are needed,
which computer vendors can follow. They allow any computer following one of these standards to
communicate with another computer following the same standard.
Standards are designed in a highly formal, structured way. To reduce complexity most networks
are organized as a pile of layers or levels. The purpose of each layer is to offer certain services to higher
layers, which these higher layers can use without knowing how they are implemented (they simply know
what is called the interface). Thus, a layer n (service provider) offers a layer n+1 (service user) services,
which are composed out of functionality the layers 1 to n provide. Only the same layers of two computers
communicate through a so called protocol, which is a set of rules for communication at one layer. Of
course, in reality no information is directly transferred between layers; the actual communication happens
through a physical medium. A set of layers and protocols is called the network architecture.
Some of the main design issues of computer networking occur in several or all layers, for
example
• an addressing mechanism is needed in order to specify a destination

• rules for data transfer: one direction (simplex communication), two directions, but not
simultaneously (half-duplex communication) or both directions at once (full-duplex)
• error detection and control
• control and restoration of right order of data
• synchronization of different speeds of sender and receiver
These and more issues have to be cleared by laying down a standard. Standards are technically
implemented by adding control information (a header) to the raw data in every layer. So, actually
transmitted are the user data plus some data needed by the network architecture to provide its
functionality.
14.3.2 OSI model

The Open System Interconnection (OSI) Reference Model was developed by the International
Standards Organization (ISO). It is an attempt to build a framework of layers, in which various protocols
in computer networking fit.
The OSI model consists of seven layers which are:
1. The Physical Layer: transmits raw data bits over a communication channel (mostly mechanical
and electrical issues)
2. The Data Link Layer: guarantees to the network layer that there are no transmission errors by
breaking the input data stream up into frames and sending back acknowledgement frames
3. The Network Layer: controls the operation of the involved subnet; main issues are routing
(determine a way from source to destination) and dealing with problems of heterogenous
networks, e.g. different size requirements of transmitted data blocks
4. The Transport Layer: splits up data from the session layer if necessary (segmentation) and
ensures that the pieces arrive correctly
5. The Session Layer: allows users on different computer systems to establish a session between
them, i.e. they are able to transfer files or log into a remote system; the conditions of
communication are laid down, for example full-duplex or half-duplex
6. The Presentation Layer: unlike the layers before it is concerned with the syntax and semantics
of the transmitted information; it is concerned with all aspects of information representation such
as data encoding, data compression and encryption
7. The Application Layer: contains a variety of commonly needed protocols like handling with
different terminal types and file systems; a label to identify the communication process, its origin
and destination application is added to the transmitted information
Layers 4 to 7 are true end-to-end layers; i.e. the layer on the source system carries on a communication
process with the same layer on the destination system. In the lower layers the protocols are between a
system and its immediate neighbour, for example the source system and a system "on the way" to the
destination.
A communication between two systems via a relay system (another computer or an interconnection
device), causes the following flow of information between the OSI architectures of the involved systems:
Note that the OSI model does not lay down the specific protocols used to communicate between
two computers on a specific layer. Although ISO recommends which protocols to use with the OSI
model, the model itself is in proper speaking no standard of computer networking. Which protocol in a
single layer is actually used, depends on several factors like the physical network, the needed reliability,
etc.
14.3.3 Classification of Networks
Computer networks can be classified based on several factors, for example bandwith, common
applications, common hardware. The most known classification is based on the physical size of the
network. Such a classification may look like this:
Interprocessor distance Processor located in same... Example
0.1 m Circuit Board Data Flow Machine

1m System Multiprocessor
10 m Room LAN

100m Building LAN

1 km Site LAN
10 km City MAN
100 km Country WAN
1000 km Continent WAN
10000 km Planet Interconnection of WANs
Data Flow Machines are highly parallel computers with many processing units working on the same task.
In Multiprocessor systems the single processors communicate via shared memory.
More important in practical use are:
• LANs (Local Area Networks), for example a computer network in a company's department
• MANs (Metropolitan Area Networks), for example a cable television network within a city
• WANs (Wide Area Networks, Long Haul Networks), for example an ISDN network
14.4 LANs: Basics
In today’s usage of computer networks Local Area Networks (LANs) are most important. More
than 50% of all installed computer systems in organizations are connected to a LAN. This means, on the
other hand, that only the organization itself is responsible for the selection and operation of their LAN.
Other than with WANs or MANs there are no legal or political restrictions.
LANs can be characterized with the following points:
• the network spreads over a small area, e. g. a single building or a cluster of buildings
• the network consists of one transmission medium used for all operations within the network
• the network runs at a high speed (from 1 Million bits per second to 100 Mbps)
• it is a peer-to-peer network, that is, any device within the network can exchange data with any
other device
• it is owned by a single organization, which is responsible for its operation
LANs can be distinguished in four major points:
1. the topology of the network: bus or ring

2. the wiring layout: linear or star
3. the used transmission medium: twisted pair, coaxial cable (baseband, broadband), optical fibre
4. the used medium access control technique: CSMA/CD or token-passing
Together these points determine cost, capacity, effectiveness and performance of a LAN. What is
more, they determine whether two LANs can be easily connected, a necessity that has become obvious
during the last few years. The single points are not independent and cannot be decided in isolation.
14.4.1 Transmission Media
There are three major forms of transmission media used for LANs:
• twisted pair: two insulated copper wires twisted together in a regular spiral pattern; one pair
establishes one communication link; it transmits electromagnetic signals. Twisted pairs are

distinguished between shielded and unshielded twisted pairs according to their protection against
electromagnetic fields
• coaxial cable: a single insulated inner wire is surrounded by a cylindrical conductor which is
covered with a shield; it transmits electromagnetic signals. Coaxial cable is classified into two
categories: baseband (uses digital signals) and broadband (uses analog signals) coaxial cable
• optical fibre: consists of three concentric sections, the core (a fibre conducting optical rays), the
cladding (reflecting optical rays) and the jacket (surrounding one or many fibres to protect them);
transmitts optical signals, which must be transformed to electromagnetic signals
Each transmission media has its own advantages and disadvantages. They differ in costs, capacity,
possible length, and electromagnetic isolation. Which media to be chosen depends on three other
characterization features of LANs: firstly, which topology is to be implemented. Secondly, which
capacity and reliability are needed.
14.4.2 Topologies and Wiring systems
The topology of a network is an abstract representation of how the devices in this network
interact. One can think of different kinds of topology (also depending whether the network is a point-to-
point or broadcasting one); for LANs bus and ring topologies are most important. The bus topology has
the general advantage that it is more flexible to extensions and offers a bigger reliability. Unlike this, the
ring topology on principle has a shorter over-all length of communication paths.
In both topologies data is transmitted in form of packets which contain a header which specifies
the destination of the packet. For each packet a system wants to send, it waits for its next possibility
(determined by the used MAC technique), then sends the packet. The destination system copies the
packet, as it is passing by. All other systems let the packet just pass by. With bus topology a packet is
absorbed by a terminator at the end of the bus. With ring topology it is removed when it reaches the
sending system a second time.
The topology has to be distinguished from the wiring system, i. e. the actual path the cable
follows. Although this seems to be an issue that can easily be neglected, it is one of the most difficult
problems in data communications. The actual wiring is constrained by physical needs like walls and
floors in buildings. Therefore linear wiring (wiring exactly following topology) often is impossible.
Alternatively a star wiring can be used, which concentrates all the wiring in one room or closet and uses
an individual cable to each device within the network. This method also increases the reliability of ring
topologies, but it increases path length as well. A given topology can be transposed in a star wiring
system as follows:
There also exists a general wiring standard (EIA/TIA-568) for commercial buildings that supports
a multiprotocol, multivendor environment. The goal of this standard is to enable laying out of wiring
systems without exactly knowing what telecommunication products will finally be installed.
14.5 Internetworking: The Internet, TCP/IP
The aim of internetworking is to connect two or even more networks with the result that they look
like one single, virtual network to the user. This network is called an internet; the networks it consists of
are referred to as sub-networks. To reach this goal different interconnection devices are needed.

Internet with a capital "I" refers to a worldwide internet built of large national backbone
networks. So, the Internet is a connection of WANs. The Internet provides the following applications in
an international scope:
• Simple Mail Transfer Protocol (SMTP): allows to send electronic mail (E-Mail) to thousands
of other computers all over the world
• File Transfer Protocol (FTP): allows sending and receiving files from one system to the other
under user command
• Telnet: provides the capability to log on to a remote computer system. The user then is able to act
as if directly connected to that system.
• Network File System (NFS): enables the user to work with a remote file system, as if it were on
the local computer (transparent)
Unfortunately, the Internet does not work with protocols according to the OSI model. Instead it
uses its own suite of protocols called TCP/IP (Transmission Control Protocol/ Internet Protocol), named
after two involved protocols. A comparison between OSI model and TCP/IP protocol suite shows the
differences:
The protocols of the Network access layer are not specified by TCP/IP. A protocol appropriate for
a particular network is used. The Internet layer protocol is IP (Internet Protocol); transport is handled by
TCP (Transmission Control Protocol). For the Application layer the above mentioned SMTP, FTP, Telnet
etc. are laid down.
14.6 ISDN: Basics
For a long time the telephone system has been the primary communication infrastructure. But it
was designed to transmit analog voice data und therefore inadequate for other (digital) needs of data
transmission, for example fax or video. The major goal of the new Integrated Services Digital Network
(ISDN) is the integration of voice and non-voice services via a full digital network, which would replace
the telephone system (and therefore is a point-to-point Wide Area Network) step by step. The idea is not
to offer the highest possible speed, but a universal connectivity. If higher capacity for one application is
needed, several independent connections can be combined to create a single, high-speed end-to-end
connection. A possible ISDN configuration may look like this:
The basic idea behind ISDN is the digital bit pipe, an abstract pipe between customer and carrier
through which bit flows. It does not matter what kind of source produced the bits. In terms of the OSI
model, ISDN provides a physical layer service onto which layers 2 to 7 can be built. ISDN uses the out-
of-band signaling concept, which is quite different from how Local Area Networks work. They use the
same cable with interleaved actual data and control data. ISDN transmits actual data and control data in
two different ways (normally, on so called B- and D-channels) at data rates up to 2 Million bits per
second (most common are two B- and one D-channel, which is 144 Thousand bits per second).
A comprehensive summary of ISDN is available. A special ISDN page contains links to many
sources about ISDN, in particular to lists of ISDN products.

14.7 Network Management: Selection and Validation
The selection and validation of networks (which in most cases will be LANs) is a subject which
should be handled in a systematic and comprehensive way. The first phase in this decision process is
planning the system. This can be done in three steps, similar to the planning process in general.
1. Defining Objectives: define what the system is supposed to do. This should be as quantitative as
possible and related to the creation, storage, transfer and processing of information. The goals
must be based on the present situation, which can certainly be improved. The whole environment
of the planned system should be looked at; there should be no restrictions at that point of the
process. This leads to some key product goals from which more specific system requirements can
be derived.
2. Describing the System: describe some options to achieve these goals. There will be no real
improvement by only buying new equipment. Organizational and procedural improvements and
adjustments are the basis for the implementation and operation of an effective computer network
as a technological improvement.
3. Determine Communication Needs: explain how information has to be moved, what the network
has to do. Network requirements have two major points: compatibility (the possibility to connect
the devices) and capacity (maximum performance of the net). Thus, the selection of a network
should take into account interconnection with other networks and future growth of the network.
In a second phase possible networks (and vendors) have to be tested to the following selection criteria:
1. total costs must not exceed expected savings

2. the network has to meet the established requirements and to provide the needed services
3. network must be expandable with only incremental costs
4. network is reliable (total network failures are prevented)
5. network can handle equipment supplied by several vendors
6. ease of installation, maintenance, reconfiguration, interconnection
7. software availability
In particular the need to connect two or more networks together should again be emphasized. The
selection of a small LAN often is very easy and obvious. Problems occur when this LAN has to be
connected to another network.
In the two phases of the selection process the responsible person has to take in a different point of
view.
14.7.1 Operation
The task of network management is to manage networks for efficient and reliable operation. This
has become necessary because of the increasing complexity and size of networks. Costs for networks
have become one of the most significant factors within overall budgets for computing and
communication. Like management in general network management means to plan, supervise and control
any activity concerning the computer network.

To manage large networks the help of automated network management tools is needed, so that the
current status and behavior of the network can be analyzed. Those network management systems show
the whole network as a unified system with the possibility to access information and change current
behavior of every part of the network. Therefore every network node contains software to collect and
store statistical data (network management entity). In addition at least one device in the network works as
a network control center, which allows access and change of this data via a user interface.
The International Standards Organization (ISO) has defined a Network Management Architecture
that specifies which functions have to be performed by a network management system and defines
protocols for the exchange of relevant management data. It consists of five elements:
• Fault Management: detect and correct abnormal operation that requires management attention
• Configuration Management: control, identify, collect data from, and provide data to managed
objects within the network; initializing and shutting down of network
• Performance Management: evaluate behavior and effectiveness of network; to accomplish this
task appropriate metrics have to be established
• Security Management: manage access to network, encryption of data, log facilities
• Accounting Management: identify costs and establish charges
Many of today’s small and mid-sized nonprofits have yet to take advantage of the numerous
benefits of computer networking within their offices. This article will examine the different elements that
make up networks suitable for these types of organizations, as well as the associated capital investment
and maintenance costs, and other factors to be considered when designing a network.
14.8 What are the benefits of a Network?
Centralized storage of files is often the initial and primary justification for a network. Instead of
having multiple iterations of documents and spreadsheets on disparate computers, files can be stored in a
centralized location. This then allows another benefit of networking, centralized backup. With a
centralized backup system, an organization’s files can be backed up daily onto high capacity tapes. This
helps ensure the long term integrity of the data.
The use of dial-up services and the Internet has grown tremendously. This growth has often
necessitated the installation of a modem on each computer. Using a network, an organization can share a
modem or dial-up connection to access the Internet or other dial up services. An inexpensive device
called a router facilitates the sharing of your network’s dedicated Internet connection, be it via dialup
using a modem, ISDN, DSL, Cable Modem or T-1 line.
In addition, networks can help to reduce other capital investment costs as well. For example,
modems, printers, scanners, and CD-ROMs are just a few of the devices that can be shared over a
network.
A more recently developed benefit of networks with the advent of the Internet is the remote
access of email and files. Using technology known as Virtual Private Networking (VPN), an organization
can access its network remotely via a secure, encrypted channel by means of either a dialup or Internet
connection.
14.9 What are the components of a Network?
Each computer on the network must have a Network Interface Card (NIC). A NIC is the
computer’s gateway to the network. The NIC attaches to the network via connection medium, usually a

wire or cable, which attaches to the other computer. When there are more than two computers, their
cables can connect to a hub. A hub is like the center of a tire with spokes emanating from it, each
connecting to a separate computer or peripheral device. Hubs come in various sizes, defined by the
number of ports or connections they offer. A switch is like an intelligent hub. A hub will broadcast a
computer’s request to every device on the network, while a switch will direct the request directly to the
recipient’s port. This helps relieve excess congestion and improve performance on the network.
Most networks also have one or more central computers called servers. A server is a powerful
version of a desktop computer. They are designed to be the managers of the network, performing such
functions as file, print and email servers.
Many organizations use routers in their offices today. Routers are devices that can connect
separate networks together. They can be used to connect remote offices together, or to share an internet
connection within the office.
To protect a network, a firewall is often used. Firewalls are devices that sit between your Internet
connection and your network. Their function is to protect your network’s security and ensure that no one
breaks into your network.
Networks require Network Operating Systems. Examples of such Operating Systems include
Windows NT, Windows 2000 Server and Novell Netware. Low and no-cost options are readily available
as well in the form of the various versions of Linux.
14. 10 What are the maintenance costs of a Network?
Network administration can be the most expensive part of managing your network. To properly
support a network, it is necessary to have someone perform daily backups, install software, perform
operating system upgrades, update virus software regularly and other important maintenance. While many
organizations attempt to train an existing staff member to fulfill this role. It is also common to hire an
employee on either a full or part time basis whose role is solely to support your network. This role will
generally cost between $40,000 and $100,000 per year in recruiting and compensation costs.
In addition to the network support outsourcing mentioned above, an organization can outsource
various other network functions to help control costs. Hosted email is growing in popularity. Instead of
investing in a dedicated email server, server and client software, these service providers can offer robust
email support using Microsoft Exchange for about $10-15 per month per user.
14.11 Summary
No organization is too small to reap the benefits of networking. Through the shared use of
peripheral devices, centralized storage and backup and the shared use of Internet connectivity, networks
can help raise the productivity of any sized organization. Proper planning and design of an organization’s
network will ensure it has a system that will evolve with the organization’s needs.
You will not become a competent network mangager or system administrator by following this
lesson; neither will you become a serious network programmer. You will, however, understand a lot more
about how networks work in general and in particular how the TCP/IP protocols (the ones used in
Internet) work.

Lesson 15 – Business Data Communication and Networks
Learning Objectives
1. To study the various kinds of networks present in the corporate world.

2. To Learn the concept of business data communication
3. To understand the role of networks in Information Systems of Enterprises
Introduction
In recent years, the world of communications has undergone enormous changes. In fact, the term
paradigm shift has become ordinary in the information systems field. However, it is definitely an
appropriate descriptor of the communications industry. The primary focus of computer technology in
the past was to provide processing power for increasingly hungry but traditional applications, such as
word processing, spreadsheet, and database applications. While computing power for application
processing is still important, today's computer buyers are paying at least as much if not more
attention to the computer's ability to connect to networks. In fact, some computer systems (for
example, network PCs and Web TVs) have been developed primarily to connect to networks. These
computers rely on other computer systems connected to a network to do most of the processing. This
change in emphasis is affecting how computer systems impact individuals, organizations, and society
by placing more information, even more computing power, at everyone's fingertips.
Transmission of voice, data, text, sound, and images pervades computer information systems
regardless of the size of a manager's computer resources. Consider the diversity of organizational
tasks that now depend on some form of communications system, The laws governing communications
also have been changing rapidly, opening up opportunities for competition between industry giants
who had enjoyed monopolies in their areas or were at least restricted from entering other
communications areas. The most recent change is the Telecommunications Act of 1996. The basic
purpose of this act is to permit any business to compete in any communications market. The law blurs
traditional demarcations in industry "turf." For example, cable TV companies used to be confined to
offering TV entertainment. These same companies are now considering offering voice
communications over their cable system and have already begun to enter the arena of data
communications by providing Internet access to their subscribers. At the same time, more and more
video and voice conversations are being transmitted over the Internet, and telephone companies have
been given the right to provide cable service to their customers. Entertainment firms have begun to
purchase or make alliances with telephone, cable, and satellite broadcasting companies. Major TV
networks have created alliances with major software firms, and local telephone companies have
entered the long-distance telephone market. Some PHS stations have begun to embed data in their TV
broadcasts, allowing PCs with a special card installed to receive the data. Even power companies are
considering entering the communications business because of the important rights of way to our
homes and businesses that they already possess
After seeing the basics and the components of a network, now we are going to see the various kinds of
network available in the corporate world and their benefits.
LAN
LAN stands for Local Area Network. These networks can consist of anywhere from two to
thousands of computers. Even a simple network of one computer connected to one printer can be
considered a LAN. Normally, LAN is a computer network that spans a relatively small area. Most

LANs are confined to a single building or group of buildings. However, one LAN can be connected to
other LANs over any distance via telephone lines and radio waves.
Most LANs connect workstations and personal computers. Each node (individual computer)
in a LAN has its own CPU with which it executes programs, but it also is able to access data and
devices anywhere on the LAN. This means that many users can share expensive devices, such as laser
printers, as well as data. Users can also use the LAN to communicate with each other, by sending e-
mail or engaging in chat sessions.
LANs are capable of transmitting data at very fast rates, much faster than data can be
transmitted over a telephone line; but the distances are limited, and there is also a limit on the number
of computers that can be attached to a single LAN.
Peer-to-Peer - Sometimes called P2P, these networks are the simplest and least expensive networks
to set up. P2P networks are simple in the sense that the computers are connected directly to each other
and share the same level of access on the network, hence the name. Computer 1 will connect directly
to Computer 2 and will share all files with the appropriate security or sharing rights. If many
computers are connected a hub may be used to connect all these computers and/or devices. The
diagram below shows a simple peer-to-peer network:
A peer-to-peer network is sometimes the perfect (and cheap) solution for connecting the
computers at a small nonprofit. However, peer-to-peer networking has its limitations, and your
organization should tread with caution to avoid headaches (security issues, hardware
inadequacies, backup problems, etc.) down the road.
Client/Server - Probably the most common LAN types used by companies today, they are called
"client/server" because they consist of the server (which stores the files or runs applications) and the
client machines, which are the computers used by workers. Using a client/server setup can be helpful
in many ways. It can free up disk space by providing a central location for all the files to be stored. It
also ensures the most recent copy of that file is available to all. A server can also act as a mail server
(which collects and sends all the e-mail) or a print server (which takes all the print jobs and sends
them to the printer, thus freeing computing power on the client machine to continue working).
Establishing the right kind of network for your organization is important to make the most of
your time and money. While a peer-to-peer network is often a good choice for small networks, in an
environment with more than 10-15 computers, a peer-to-peer network begins to become more trouble
than it is worth: your computers start to slow down, you can never find the file you are looking for,

and security is non-existent. If this is happening in your organization, it is probably time to switch to a
client-server network by bringing in a dedicated server to handle the load. The server is called
"dedicated" because it is optimized to serve requests from the "client" computers quickly. The
diagram below shows a simple client-server network:
What is a server?
A server is simply a computer that is running software that enables it to serve specific requests from
other computers, called "clients." For example, you can set up a file server that becomes a central
storage place for your network, a print server that takes in print jobs and ships them off to a printer, as
well as a multitude of other servers and server functions.
A server provides many benefits including:

• Optimization: server hardware is designed to serve requests from clients quickly
• Centralization: files are in one location for easy administration
• Security: multiple levels of permissions can prevent users from doing damage to files
• Redundancy and Back-up: data can be stored in redundant ways making for quick restore in
case of problems
The client-server model of networking is the way to go for larger organizations. Once you have a
client-server network set up, it should provide you with more flexibility than a peer-to-peer
network as your needs change. For example, as network traffic increases, you can add another
server to handle the additional load. You can also consider spreading out tasks to various servers,
ensuring that they are performed in the most efficient manner possible. Most importantly, a client-
server network is much easier to secure and back up, greatly improving the reliability and
confidentiality of your data.
Wireless Networking
Wireless networking products have become more popular in the last few years due to an
increase in competition among manufacturers and the emergence of a more dominant wireless
technology standard. This section looks at the benefits and drawbacks of wireless networking and
provides further resources for research into wireless products. Wireless networking refers to hardware
and software combinations that enable two or more appliances to share data with each other without
direct cable connections. Thus, in its widest sense, wireless networking includes cell and satellite
phones, pagers, two-way radios, wireless LANs and modems, and Global Positioning Systems (GPS).

Wireless LANs
Wireless LANs enable client computers and the server to communicate with one another
without direct cable connections. Generally, a wireless LAN is connected to an existing wired LAN,
although they can exist without a wired LAN (in this case, users will only be able to communicate
with other users on the same subnet).
Necessary components include an access point, Client LAN adaptors and the wired LAN. The
access point is a device that translates between the wired LAN and the wireless LAN. The Client
LAN Adaptors are PC cards, PCI or ISA boards that plug into laptop or desktop computers equipped
with radio transceivers to communicate with the Access point. Other components to a wireless LAN
can include Extension Points and Directional Antennas. Extension Points are devices similar to the
access point, but not connected to the wired LAN. Extension points serve to extend the range of the
wireless network by relaying signals from client computers to the Access point. Directional Antennas
serve to connect wireless networks located at a greater distance from one another. Each network
would have an antenna targeted at each other (known as a "line of site" connection).
How a Wireless LAN works?
In a typical wireless LAN configuration, the access point connects to the wired network from a fixed
location using standard cabling. The access point receives and transmits data between the wireless
LAN and the wired network infrastructure. A single access point can support a small group of users
and can function within a range of less than one hundred to several hundred feet. End users access the
wireless LAN through the wireless-LAN adapters installed in their computers.
Benefits of Wireless LANs
Cost: Wireless LANs can cost less to implement than wired LANs, especially in situations where
implementing a wired LAN requires extensive labor and materials to install the wiring and drops. For
environments that are difficult to wire (such as schools or temporary spaces) a wireless network can
be more cost-effective in the long run than a wired one.
Simple/flexible to Install: Wireless LANs eliminate the time needed with wired LANs for laying and
pulling wires, and can reach places that cannot be reached by wires.
Portability: Wireless LAN systems can move physical locations much easier than wired LANs,
reducing total cost of ownership for organizations that are on the move.
Mobility: Wireless LAN systems can provide LAN users with access to network information
anywhere in their organization.
Scalability: Wireless LAN systems can be configured for small offices and large, with peer-to-peer
systems or large established LANs, specific to the localized need of a workgroup or across the whole
enterprise. Wireless LAN systems grow easily with the need by adding more access points, client
LAN adaptors and extension points. Wireless can be a good solution if you need to connect several
buildings without installing a wired connection. Wireless LAN bridges can extend LANs that are
typically one to five miles apart. These wireless bridges span multiple-building LANs without
incurring the monthly costs of a T1 or higher speed lines.
Drawbacks of Wireless LANs
Cost: In environments with installed wiring or less demanding wiring needs, the up front costs of
adopting a wireless LAN system can be more expensive than with wired LANs.

Interoperability: There are several competing technologies used by wireless LAN vendors to
communicate data between hardware, with no ability for communication directly between systems
using these different standards.
Interference: Most of the wireless devices today operate on 2.4-GHz radio bands, which are also
used by cordless phones and most microwave ovens. The potential for interference when used near
other devices sharing the same frequency band.
Speed: Most commonly used wireless LAN products are rated for a maximum 11Mbps throughput,
and in practice see speeds about 80% less than this - some wireless LAN products are rated for speeds
much less than this (HomeRF systems for example). Still quite speedy for most network needs and for
broadband Internet sharing, but for larger offices with high network traffic and demands for speed,
this should be taken into consideration.
Wide Area Networks (WANs)
Wide Area Networks or WANs are very large networks of computers. These networks span
large geographical areas, generally covering a couple miles, sometimes connecting computers
thousands of miles apart. A WAN can also be a collection of LANs, bringing together many smaller
networks into one large network. A WAN can constitute a very large corporate or government
network, spanning the country or even the world. In fact, the Internet is the largest and most common
WAN in existence today.
Normally, it means a computer network that spans a relatively large geographical area. Typically, a
WAN consists of two or more local-area networks (LANs).
Computers connected to a wide-area network are often connected through public networks, such as
the telephone system. They can also be connected through leased lines or satellites. The largest WAN
in existence is the Internet.
Controller Area Network (CANs)

Last modified:
Abbreviated CAN, a serial bus network of microcontrollers that connects devices, sensors and
actuators in a system or sub-system for real-time control applications. There is no addressing scheme
used in controller area networks, as in the sense of conventional addressing in networks (such as
Ethernet). Rather, messages are broadcast to all the nodes in the network using an identifier unique to
the network. Based on the identifier, the individual nodes decide whether or not to process the
message and also determine the priority of the message in terms of competition for bus access. This
method allows for uninterrupted transmission when a collision is detected, unlike Ethernets that will
stop transmission upon collision detection.
Controller area networks were first developed for use in automobiles. Equipped with an array
of sensors, the network is able to monitor the systems that the automobile depends on to run properly
and safely. Beyond automobiles, controller area networks can be used as an embedded
communication system for microcontrollers as well as an open communication system for intelligent
devices.
The controller area network, first developed by Robert Bosch in 1986, is documented in ISO 11898
(for applications up to 1 Mbps) and ISO 11519 (for applications up to 125 Kbps).
Campus Area Networks (CANs)
An interconnection of local-area networks within a limited geographical space, such as a school

campus or a military base

Metropolitan Area Networks (MANs)

Last modified: Tuesday, February 03, 2004
A data network designed for a town or city. In terms of geographic breadth, MANs are larger than
local-area networks (LANs), but smaller than wide-area networks (WANs). MANs are usually
characterized by very high-speed connections using fiber optical cable or other digital media.
Virtual Private Network (VPNs)

Answer:
A virtual private network (VPN) is a private data network that makes use of the public
telecommunication infrastructure, maintaining privacy through the use of a tunneling protocol and
security procedures. A virtual private network can be contrasted with a system of owned or leased
lines that can only be used by one company. The idea of the VPN is to give the company the same
capabilities at much lower cost by using the shared public infrastructure rather than a private one.
A VPN connects computers located at various places throughout a city, a state, or even globally. It
provides a secure network connection for distance computers and does not require laying cable to
supply the connection. You can set up a VPN yourself (Windows 2000 server has settings to establish
a VPN) or you can purchace one as a service from another company.
Home Area Network (HANs)
A HAN is a network contained within a user's home that connects a person's digital devices, from
multiple computers and their peripheral devices to telephones, VCRs, televisions, video games, home
security systems, "smart" appliances, fax machines and other digital devices that are wired into the
network.
An Introduction to Wireless Networks for the Small/Medium Enterprise (SME)
Wireless Networking, WiFi, is not a new technology, but it is only recently that it has become
mainstream. What are the benefits of wireless networks and should you be considering using it?
The advent of portable computing devices is one of the main drivers for the adoption of wireless
networking. Today, around 50% of new laptops come wireless enabled out of the box. All of Apple's
latest line of laptops comes with both wireless & bluetooth built in. Many Microsoft Windows laptops
are similarly wireless enabled.
A powerful alliance of vendors joined together in 1999 to form the WiFi Alliance. You can be assured
that any device approved by the WiFi Alliance will interoperate happily with any other approved
device. The term WiFi has become corrupted in common usage to mean wireless networks in general,
not just devices approved by the WiFi alliance.
Why adopt WiFi?
Today's workforce, equipped with PDAs, laptops and other mobile devices, demand access to your
network from wherever they are, without the hassle of a fixed network. WiFi allows your business to
deploy a network more quickly, at lower cost, and with greater flexibility than a wired system.
Productivity increases too, since workers can stay connected longer, and are able to collaborate with
their co-workers as and where needed.
WiFi networks are more fluid than wired networks. A network is no longer a fixed thing, networks
can be created and ripped down in an afternoon instead of the days or weeks required to create a
structured cable network.

Architecture
Wireless cards can operate in two modes, Infrastructure and Ad-hoc.
Most business systems use wireless in Infrastructure mode. This means that devices communicate
with an access point. Typically the access point also has a connection to the company wired network,
allowing users access to servers and files as if they were physically attached to the LAN.
Ad-hoc connections are direct connections between wireless cards. This type of connection is more
common amongst home users, but if used by business users could have serious management and
security implications.
Management
You can easily connect to a WiFi network anywhere within range of an access point. This is a boon
for your workers, but unfortunately, it also brings with it a few headaches for the IT department.
Security
Security is the bane of everybody who puts together a wireless network. access points, using factory
default settings, are not secure at all.
So, if security is such a concern does that mean I shouldn't deploy WiFi? No, it doesn't. But it is
something that you should bear in mind when in the planning stage.
When talking about security there is no such thing as having a completely secure system. Everything
is insecure to some degree or other. The degree of security you require is dictated by the sensitivity of
the information you possess.
If you require very high levels of security then you cannot rely on the built in security measures of a
WiFi network alone. On the other hand, most small to medium sized companies do not require very
high levels of security.
Integrating Enterprise Information on a Global Scale
In today's challenging business environment, companies are encountering levels of growth and change
that can quickly make their business information systems obsolete. These enterprises are meeting this
challenge by implementing real-time transaction processing systems to reduce cycle time, cut
operation costs, and improve responsiveness to corporate users, customers, and vendors alike.
This section highlights the key factors that an organization must address when building a globally
integrated business system. It also describes how 3Com Corporation implemented its own state-of-
the-art enterprise resource planning (ERP) system using SAP R/3 business application solutions, the
Informix OnLine Dynamic Server relational database, and 3Com's own networking systems and
products. In addition, the paper touches on the advantages that the partnership between 3Com and
Informix offers networking customers.
Thriving in a Volatile Business Climate

Many industries today are characterized by fierce competition, intense time-to-market pressure, and
consolidation through mergers and acquisitions. Companies depend on their transaction processing
systems to maintain a competitive edge, and to sustain business models that must constantly adapt to
changing market conditions.

An effective business system is a marriage between information system (IS) and business process.
When laying out a strategic plan and defining the underlying architecture for a new corporate
transaction processing system, most organizations seek to achieve these primary objectives:
• Make business operations more responsive to customers and the needs of the
enterprise by integrating logistical data into one global system
• Implement real-time transaction processing to provide online information access
anytime, anywhere
• Develop processes that reduce cycle time for order fulfillment and minimize
inventory and distribution costs
• Design a future-proof solution that can scale easily to accommodate growth
• Leverage technology to reduce long-term IS costs
Information technology has progressed dramatically in the last few years. It is now possible to
integrate diverse functions more fully using software that offers better price/performance as well as
plug-and-play modularity. The latest technology also makes it possible to combine data in a scalable,
high-performance relational database, and to transmit the information globally over a reliable high-
speed network.
A business information system may be divided into three major elements: the ERP applications, the
database, and the network configuration. Each of these elements is equally important, and all of them
must mesh smoothly to ensure a successful implementation.
Success Factors
Here are some key factors that can help ensure successful implementation of a large-scale business
system:
1. Keep the network as flat as possible for simplicity and efficiency. Utilize switching
for high performance where you can, and use routing where you must at the network's
edges and where security is a key issue.
2. Resist the tendency to over design; you cannot cost-effectively design a completely
fail-proof network. Rather, design the network so that a failure in one area will not
impact the business processes across the entire enterprise.
3. Put all application and database servers on their own Domain Name Service. This will
avoid single points of failure. Again, keep the applications environment as flat as
possible.
4. Involve the network management organization as a peer member on the business
system implementation team from the beginning. Application management and
bandwidth management are both important.
5. Commit to extensive training for users and managers. In-depth training early in the
process will minimize the negative impact on productivity of introducing a new
system.
6. Engage a consultant to ensure successful implementation. 3Com benefited greatly
from Price Waterhouse's experience in R/3 implementations.
7. Conduct stress testing up front. Be prepared for constant refinement of baselines.
Summary
LANs and WANs in general are similar in the sense that they are collections of computers.
However, there are huge differences between the simplest P2P LAN and a WAN. Whereas it is fairly
easy to connect two computers to each other and to a shared printer to for a simple P2P LAN, trying
to build a safe and secure LAN takes considerable time and resources. Understanding your
organization's needs, the size of the network to be built, the complexity, and the fundamental

differences between the different types of LANs and WANs will help you to build the most effective
network for your organization.

UNIT III
Lesson 16 - Telecommunications and Networks
Learning Objectives
1. To know more about the communication channels and the transaction media
2. To study about the telecommunication Technology and its uses in business scenario.
3. To know about the Information Super Highway.
16.1 Introduction
Even as we enter into the new millennium, the digital revolution is profoundly altering our socioeconomic
fabric. The fields of data communications, telecommunications, distributed computing and networking has been
changing so fast as to blur the distinction between these fields altogether. With phenomenal advances in
networking, it is now feasible to link together desktop computers, minis and mainframes distributed across the
globe to collaborate and enhance organizational productivity. The advent of numerous broadband technologies, the
trend towards digital convergence, the lowering costs and increasing speeds of computer processor chips, the trends
toward globalization in the industry are all driving a movement toward distributed computing. Scalability,
Interoperability, Connectivity, Security, Agility, are but some of the key issues that a firm needs to focus on while
building its networked information systems.
The most important aspect of this digital revolution is that it involves a bewildering array of technologies
that are continually in flux; and this offers the manager with a new set of challenges. It is necessary to be able to
understand and interpret these technologies, and evaluate them comparatively on a cost-benefit basis, and to see
how different technologies may be deployed in a mix-and-match strategy, to make strategic IT investments. The
manager who does not understand the trends in the technologies underlying the networks will suffer. Further, the
entire spectrum of E-Commerce business models are based on exploiting key advantages offered by the underlying
infrastructure. Designing new EC business models, evaluating proposed models, competing against existing models
all require managerial insight into the opportunities and constraints posed by the technological infrastructure, as
well as the agility to keep track with its changes and adapt quickly.
Thus, unlike ever before, the IS manager of the dot com era must have an elementary understanding of the
technology that drives this economy, and an aptitude to continually refresh that understanding, as part of his or her
arsenal, for survival. The most important constraint faced by E-commerce ventures is a shortage of managerial
manpower, and the cost of interfacing between managerial and technological workforces. IS professionals with the
training to meet this challenge will find endless opportunities in the market.
The content of this lesson is geared for the needs of an IS professional – it is not meant to be an
engineering knowledge. We will explore pure technical issues as much as they are necessary to form managerial
insights into various competing technologies. We will learn how to do evaluations of technologies for specific
contexts, and make investment recommendations. We will examine the economic factors that drive
convergence and the powerful economic effects of open standards and connectivity. Finally, this is NOT an e-
commerce class. But, it will serve as an essential tool to understand e-commerce.
16.2 The Telecommunications Revolution
Anytime, anywhere, any way is the mantra of many computer users. Improving telecommunications
technologies, the process of electronically communicating information, are making it possible.
The Marriage of Computers and Communications
You simply can't pick up a newspaper or magazine or watch television without hearing about the
explosion of telecommunications and networks. Some experts point to the early 1990s and the breakup of the
AT&T monopoly as the turning point in this revolution. That one incident, along with the growth in personal
computers since then, could very well be how all this started. Those two forces now seem to be changing every
facet of our lives.
16.3 The Information Superhighway
You can hardly keep up with the mergers and acquisitions in the telecommunications and entertainment
industries. Many people compare the present-day Information Revolution to the Industrial Revolution at the
turn of the 20th century. You can easily draw many parallels between the two.
You could also look at the development of our interstate highway system and the changes it brought as
another example of how the information superhighway is changing things. Whole towns have sprung up around
the interstate highway exchanges. Other towns have literally disappeared because they weren't located close to
the interstate. Some businesses make it a corporate strategy to locate only at busy highway intersections.

When most people think of the information superhighway, they immediately think of the Internet. But
the many networks developed by private corporations and public entities are also part of the superhighway. All
these networks together are creating what some pundits call "the death of distance." People and companies are
developing whole new ways of working, playing, learning, and communicating.
We need to know how these networks are actually constructed and discuss the various elements
involved in connecting all these computers. Knowing how it all works can give you insight into the changes that
have taken place and an idea of what the future holds. You can also get ideas about how you can take advantage
of the future now!
16.4 Components and Functions of a Telecommunications System
The following Figure shows the hardware and software components of a telecommunication system.
We'll be explaining how the pieces fit together throughout this lesson.
Components of a telecommunications system.

Remember that data moving across the Internet and other networks are not limited to text, but also
include video, audio, and pictures. This fact alone explains many of the mergers between telecommunications
companies and entertainment companies. They are starting to understand that there is a whole new way of
delivering not just information, but also entertainment via networks.
Telecommunications System Components
Some people look at networks simply as one computer hooked to another by a piece of wire. Networks
are a little more involved than that: There are many, many pieces of equipment between those two computers:
look again at the above Figure. We'll dissect and examine the equipment and the functions each element serves.
The major element that gets all the hardware and software working together is the protocols. Let's say
you attend a football game between the UK and Argentina. Can you imagine how confusing the game would be,
not to mention unfair to one side or the other, if UK followed one set of rules while the Argentina used a totally
different set? It's the same for computer networks.
Protocols are used to tell the hardware components how to transmit data within a network and between
networks. They can also be thought of as a set of rules and procedures for exchanging information between
computers in networks. They define how the various communication links are established, how information is
transmitted, and how errors are detected and corrected between networks. Most important, the use of protocols
allows different makes and types of computers to talk to each other.
Protocols are usually embedded in the software for the particular application that you want to use to
complete a function on the network. If you've used the Internet at all, you've used protocols but probably didn't
even realize it. Do these sound familiar?
• Hypertext Transfer Protocol or http, used for the Web

• Simple Mail Transfer Protocol or SMTP, used for email

• File Transfer Protocol or FTP, used to transfer files between one computer and another computer
• Transmission Control Protocol/Internet Protocol or TCP/IP, used to connect networks
The last one might have tripped you up a bit because it's not as obvious as the others. TCP/IP is the
protocol that allows you to access the Internet itself through your Internet service provider or a direct
connection through your school or workplace.
We noted that many companies are building interfaces to their databases that allow employees to pull
data from dissimilar systems and assimilate them into a coherent output form. The use of the Internet Protocol
within software programs is what allows that to happen.
Types of Signals: Analog and Digital
As we've said many times throughout this course, the computer understands only zeros and ones.
Everything going into a computer system must be transformed into digital signals. In the networking world,
however, most of the data are transmitted over telephone lines. These lines don't recognize zeros and ones. They
only understand what are called analog signals. To change the signals back and forth between analog and
digital transmission methods, you need a modem.
The purpose of a modem (modulator/demodulator) is to:
• Change digital signals from computers to analog signals that telephone lines can carry
• Change analog signals back to digital signals that the computer can understand
Communication Channels
A channel is the facility through which information is transmitted between physical locations in a
network. That's just a fancy way of saying that a channel is the highway on which data travel. Think again about
the interstate highway systems. The road surface on which you drive is a good analogy to a channel. The road
can be built from concrete, blacktop, or combination of the two. The channels on the Information Superhighway
can be built using combinations of materials such as wires, microwave stations, and satellites.
When the telecommunication companies want to wire a building, generally they run one major line
from the main fiber-optic cable to the building. Then they can hook up individual computers and telephone lines
within that building. When you do the same thing with individual homes, costs increase dramatically.
All the transmission channels discussed in this section combine to give you what seems to be a single
clear channel from one physical location to another physical location. In fact, it is very likely that when you
access the Internet and call up the Gardening Web site, you are using a combination of twisted wire, fiber-optic
cable, microwave stations, and satellites to get from your computer to the other computer.
When you transmit the latest information from the Garden.com Web site to your personal computer, the
speed at which it moves across all the transmission media is measured in bits per second (BPS) or the baud
rate. The bandwidth of a communication channel is measured by the difference between the highest and
lowest frequencies that can be transmitted by that channel.
Communications Processors and Software

In most cases you won't use front-end processors, multiplexers, concentrators, or controllers on your
personal computer. These pieces of equipment are used on larger networks and are reserved for the techies.
They are interesting pieces of the puzzle, though, so let's go ahead and look at them.
Sometimes the host computer on a large network gets overloaded processing data, monitoring
transmissions, controlling the system, etc. That's where front-end processors come in handy. Front-end
processors don't store data or application programs. You can't use them for general computing. This type of
computer does nothing but process the electronic transmissions between computers on a network system. It's
there to relieve the host computer from transmission processing so the host can serve your basic computing
needs.
A Concentrator is a telecommunications computer that collects data signals and holds them. When
enough signals are collected, the computer sends them on to the host as a batch. A controller computer simply
processes signals between the CPU and terminals, printers, or other peripheral devices attached to the network.
Multiplexers are similar to front-end processors, but their location inside the network is different. Let's
use a hypothetical situation that is becoming more and more common in businesses throughout the world.
Suppose your local bank was bought out by a big bank in New York City. New York City, you scream. How
can that be? Oh well, you sigh, how will I be affected? Probably not much. The local branch will still exist but

will be electronically connected to the big bank. The home office will install a small network of computers, let's
say 10 terminals, in the local branch.
Remember that each computer in a network must be connected to the other computers in the network
and in turn, each computer must be connected to the host computer in the center of the network. Does it make
sense for each of the 10 terminals to be separately wired to the host computer in New York? You'd have to use a
separate telephone line for each computer - that's 10 telephone lines. Typically each terminal will only be used a
small portion of the day. So if terminal 1 is transmitting only a few times a day, and terminal 2 is transmitting
only a few times a day, and terminal 3 is ..... well, you get the idea.
What the New York bank will do is install a multiplexer component in the branch to which each of the
10 terminals will be connected. The multiplexer gathers the signals from each terminal and transmits them to
the New York bank over a single transmission line. Now you're talking efficiency.
Routers
How does your Internet Service Provider manage to send your email to the right place? We're talking millions
and millions of people sending email every day. If you ever noticed, each computer user connected to a network
has a separate, individual address. No two addresses are exactly the same. All of these addresses are stored on
various computers placed around the networks. Software stored on routers uses these addresses to route the
data to the right location. Routers use protocols to help route data around the many networks to get them to their
correct destination.
Routers also allow different types of computers on the various networks to "talk" to each other. If you are using
a PC with a Windows 98 operating system, and you want to send an email to someone who is using a
Macintosh computer with the MAC operating system, you can do that because of the router. Still puzzled? See
if this helps: You own a LG television set hooked up to a cable service. Your neighbor owns a Sony television
set and uses a satellite to receive programming. How is it that both of you can receive "Star Sports" at the same
time? "Back-office" technology allows the signals to be adapted to various makes and models of televisions and
to the varying methods of sending those signals through to your television. That's what routers do on a data
network
The system of routers and associated transmission media form what's known as a network backbone.
Think of your own body. Without your backbone, you'd have a tough time standing, sitting and moving. That's
similar to a network backbone. All the computers, physical wires, wireless media, processors and software
come together in a network backbone to give us a whole new way of communicating.
Protocols are the rules used in networks to ensure that transmissions can pass between the various
components. Communication channels consist of wired and wireless media. Processors and software are
combined with the protocols and transmission media to form a network backbone. Many small networks can be
connected to form larger networks, which in turn can be connected to the Internet.
16.5 More Communications Networks
We have already discussed about the various types of networks in the previous chapters. Here, we will see the
rest also in relation with this telecommunication technology.
Private Branch Exchanges (PBX)
In the past, a private branch exchange (PBX) was restricted to carrying telephone traffic. Now it's
been adapted to carry data also, but only in a very small geographic area. For instance, if you have a small
company with perhaps 15 offices in one geographic location, you could use a PBX to link your computers to
shared printers and also use it for telephone traffic. It is a little cheaper to use this setup, although it would limit
how much data you could send between the computers and any peripheral devices.
Value Added Networks (VANs)
So you're an entrepreneur or a very small company just starting out and don't have a lot of money to
sink into computers, processors, and transmission media. You still want the capabilities offered by the
technology, though. No problem; hook up with a value-added network (VAN) and you're in business. VANs
offer the processing capabilities and latest technologies on a contract, pay-as-you-go basis. They are private,
multipath, data-only, third-party managed networks used by many organizations. Outsourcing your network
hardware requirements to another company can save you a lot of upfront money. Later on, when you're
successful and growing, you can increase your processing capabilities with the VAN or go ahead and purchase
the technologies on your own. The value added through a VAN is the technical expertise they offer in addition
to the hardware capabilities.
Network Services
Think of going to the grocery store and buying a week's worth of food. For some of us that may be 20
packages of Maggi noodles; for others that could be quite a lot of food. You buy all the things, load them all in

to your cart, and head for the checkout line. You pay for your food while it is being bagged. Assuming you
bought lots of items, not all of them are packed into the same bag. You probably will have four or five bags,
maybe more. You take them home, unpack the bags, and reassemble all your goods in the cupboard. You've just
experienced packet switching.
Packet switching is a method of breaking large blocks of text into smaller chunks of data and routes
them in the most economical way through whichever communication channel is available. When you read this
lecture file on the Web, it appears as though all the data came into your client computer together. But they
didn't. The data were broken into small packets on their way out of the server computer and then sent to and
reassembled on the client computer. It happens so quickly and so efficiently that you don't even notice. Packet
switching also checks transmission errors when data travel from one location to another. Make sure you read
the text to understand the technical aspects of how packet switching operates.
Frame relay is a cheaper and faster way of sending data. It packages data much like packets but doesn't
check for transmission errors. Therefore, you'd want to use frame relay only on very reliable transmission lines.
Many of us complain about the slowness of the transmission lines on our computers, especially if we are using
the computer at home. Most telephone lines are slow, and the modems on our home computers are even slower.
The telecommunication companies are working hard to remedy this problem and create technologies that will
greatly increase the speed at which we access data on the Internet. One of the most promising technologies now
is the Asynchronous Transmission Mode (ATM). ATM ties all the disparate parts and pieces of a network
into what will appear to the user as one. It is able to process transmissions and all kinds of data more efficiently
and at a higher speed.
A few years ago, Integrated Services Digital Network (ISDN) was the Holy Grail of fast data transmission. It
is a complicated technology to install on computers, especially personal computers, so its appeal has lessened.
The other emerging technology is the Digital Subscriber Line (DSL) which will increase the capabilities of the
regular telephone lines to process more than just voice data. DSL will be able to carry voice, data, graphics, and
video at a greater capacity than the current ISDN lines.
Since many home computer users already have cable TV installed in their homes, the telecommunications
industry is using cable modems to pump data into the home via cable TV. Because the technology limits the
data flow to one way, cable modem users still need a regular modem to send data out to networks.
Larger organizations, such as universities and corporations, can afford a T1 line, which support extremely high
rates of data transmission. These lines are capable of carrying voice and data transmissions over 24 channels,
which makes them ideal for larger networks. Because T1 lines are expensive, they are not something you'd
install in your home.
The important thing to remember with all this new technology is that nothing is standing still. The
telecommunications and computer industries are working at breakneck speed to improve and expand the
networking experience not just for companies, but also for home users.
16.6 Enterprise Networking and Standards
It's likely that as a company grows, so will its networking capabilities and needs. Through enterprise
networking, a company can build a new network and connect it to existing, separate networks. We noted
earlier how different types of computers can be connected through the use of software so that you don't have to
replace your current computers.
One way that companies are increasing and improving their current system technology without purchasing all
new information systems is through the use of TCP/IP protocols. Remember we mentioned before that
companies can create interfaces for different databases to access information without actually combining the
data physically in one huge computer. They do so through the use of the Internet protocol (IP). Using this
protocol, they can reduce the disruption to the organization and decrease the overall costs of adding to their
networks.
Connectivity and Standards
Typically, individuals connect to the Internet through an Internet service provider. However, businesses
have to create their own networks. In order to compete, organizations must create their own proprietary
networks and measure how well their computers and computer-based devices communicate and share
information. This measurement is called connectivity.
Computer users often lament the fact that it's difficult to share data between different platforms. Most of
this problem is resolved through open systems: nonproprietary operating systems, user interfaces, and
networking protocols. Open systems allow users to exchange data and information easily and efficiently without
worrying about the type of hardware used on the individual computers.
Electronic Commerce and Electronic Business Technologies

Probably no other aspect of computing is proving to be as exciting and as challenging as E-commerce.

Just a few years ago many corporations and businesses dismissed E-Commerce as a fad. Just the opposite has
happened: E-commerce is growing at a tremendous rate. Companies, large and small, are struggling to develop
their E-commerce capability and figure out how to do business on the Internet.
Facilitating Applications
What most businesses are starting to realize is that E-commerce is more than just throwing a nice-
looking Web page with fancy graphics out on the Internet. You have to build new processes or change your
existing methods. But it is extremely difficult to merge the old, traditional methods with the needs of the
Internet. For instance, if you take orders for your business through email, who is going to monitor the email and
process the orders? If you establish teleconferencing and data conferencing as a way of reducing travel costs
and increasing collaboration with distant locations, what kind of equipment do you need and who will be
responsible for maintaining that equipment? In fact, it may very well be more expensive to establish an E-
commerce operation than to create or grow an "old-fashioned" business.
More email messages are sent each year than are regular letters through snail mail. Email is the most
used Internet service. Free email Web sites are springing up every day. Email has the capability of quickly and
efficiently relaying information to one or a hundred people. It's fast, convenient, and easily molded to an
individual's needs. You can attach documents destined for an important client, the boss, or Grandma!
Voice Mail is available to business and now, to home users. Commercials portray Mom and Dad
throwing away the ancient answering machine in favor of a voice mail system which has a separate area for
each of the kids. Voice mail is an excellent example of how analog signals (voice) are transformed into digital
data, stored on a central computer, and then later transformed back to analog signals when an individual
retrieves messages. Just like email, you can keep the message, delete it, or send it to someone else.
With the advent of email and its ability to send documents around the building or around the world,
why has the Fax machine survived? Because many small businesses and individuals still don't have
connectivity to networks or the Internet and find it more convenient to use this technology. Now you can find
hyper-machines that combine the technologies of a scanner, printer, copier, and fax machine all in one. They
definitely save space on your desk!
Often E-commerce and E-business includes the capability of teleconferencing, data conferencing, and
videoconferencing with employees or customers around the world. These may sound like the same technology,
but they aren't. Here's the difference:
• Teleconferencing: basic technique of conferring simultaneously via telephone or email groupware
• Dataconferencing: teleconferencing coupled with the additional capability of working on the same
document or data simultaneously
• Videoconferencing: teleconferencing with the additional capability of viewing participants via video
screens
• Groupware: allows many people to work collaboratively across the room or across the world.
Electronic Data Interchange and Electronic Commerce
Electronic Data Interchange (EDI) allows two businesses to send documents to each other
electronically instead of using the old-fashioned paper trail. While EDI does decrease the cost of manual
systems and greatly reduce the chances of error, it is more expensive to set up than a Web-based system. Both
ends of the EDI must have the equipment and software to handle the system and people must be trained in its
use. These requirements have made EDI cost-prohibitive for small companies: they are essentially locked out of
the opportunity to do business electronically with customers and suppliers. Web-based commerce is much
easier for smaller companies because of the use of standard software and because they don't necessarily have to
purchase special equipment or software. We'll look at Web-based or Internet-based E-commerce more closely
in the next lesson.
The cost of doing business on the Internet is not easily apparent. Many organizational changes must be
made which add to the bottom line. E-commerce and E-business involve more technologies than just
computers: tele-, data-, and videoconferencing are vital elements of doing business electronically. Email is the
most widely used service on the Internet. Businesses must consider using all available technologies and
resources when tackling E-commerce and E-business.
16.7 Management Issues and Decisions
The Challenge of Managing Enterprise Networking

The television commercials make it sound so easy; "Just click here and you can start networking
tomorrow." They fail to tell you about all the issues, problems, and opportunities you'll have with managing an
Enterprise Network. So we'll tell you about some of them now.
As technology invades every facet of our lives, both at work and personally, the average person is
becoming well versed in its use. Most of the time you, as a manager, can leverage this to your advantage. After
all, what Joe in Production learns on his home computer can very well be incorporated into his computer use at
work. However, you increasingly run the risk of renegades creating databases and programs that are
incompatible with the rest of your system. It can cost you and the rest of the company a lot of time and money
to rein in their efforts and ensure cohesion throughout the organization.
You do have to give the end users some latitude, though, so they don't feel stifled by the system. You just need
to impress upon everyone the need to stay in touch with the rest of the organization and the fact that information
is a companywide resource.
Organizational issues come into play when you are establishing or changing work methods in
conjunction with networks and especially E-Commerce. Organizational cultures are powerful forces that you
have to deal with and that have a pervasive influence on any organizational change.
We've alluded to it before, but it becomes very evident with networks that there are a lot of hidden
costs. You can't just count the dollar cost of the necessary hardware and software. You have to consider the
disruptions to everyday work while you're establishing the network. What about the extra training users require?
It's not free! And you have to hire new people who have the expertise to build and maintain the network.
While we're talking about costs, what about the money you could lose if the network quits working
(downtime) or its security is compromised? As soon as you hear "Oh this is a piece of cake" regarding
networks, you need to grab the aspirin. The more complex your network, the more costly it will be. Not just to
build it, but to fix it when it breaks down. You, as a manager, have the responsibility to manage your enterprise
networking operations just as you would any other operation.
You have to:
• Manage the changes. These include reengineering the business processes taking place behind the
scenes and the organizational changes affecting the people.
• Train the people. Include both the Information Technology staff and the end users in your plan.
• Manage data as a vital organizational resource. Determine your organization's vital data, who
will be responsible for them, who will have access, and how you will determine accuracy and
viability.
• Plan for the future. Hopefully your business will grow and so too should your network. Too often
managers allow the network to lag behind the rest of the business; don't be one of them.
The Telecommunications Plan
Just as you plan for new opportunities in other areas of your company, you should have a
telecommunications plan that spells out how technology can enhance your operations, increase your
competitiveness and meet your customers' needs and wants. Approaching enterprise networking haphazardly
will cost you time and money.
Where do you start? First, inventory your current equipment, your current processes, and your current
needs. Determine where you are before you try to figure out where you're going. Then investigate opportunities
your organization can take advantage of using networking technologies.
Your plan should mesh with your overall business plan to provide support for your organization. Compare
where you are presently in your core business processes and where you want to go. How well does your
telecommunications plan meet your business needs? You might be surprised to find through careful analysis
and comparison that the two conflict.
Finally, take a look at the potential for telecommuncations to affect your organization. By giving your sales
force better networking equipment, could you reduce the time it takes to process an order? If you increase the
efficiency of your network, is it possible to increase the number of loan applications processed by each
employee?
Implementing the Plan
Now that you know where you're going, how are you going to get there? To summarize the text:
• Determine the necessary topology: LAN, WAN, VAN, or Network Services
• Determine the type of services offered: Voice mail, email, teleconferencing, dataconferencing
• Determine the type and level of security: private lines, dedicated leased lines, public lines

• Determine the accessibility: multiple access for a thousand workers or limited access for a small
number
• Determine the utilization: high-frequency, high-volume, low-frequency, low-volume
• Determine the cost: include development, operations, maintenance, expansion, and overhead
• Determine the installation difficulties: transmission media, hardware, software, and persware
• Determine the connectivity standards: getting all the pieces to work together
Assess your needs according to the information presented in this chapter and match the technologies to them.
It's extremely hard work. The more planning you do up front, the more you understand all the issues involved,
the less likely you'll later be managing a disaster.
16.8 Summary
While there are many problems associated with establishing and maintaining networks, they are a necessity in
today's business environment. Managers have to understand the requirements of their business and then build a
network accordingly. They also have to manage the necessary changes and remember to treat information as a
valuable resource.

UNIT III
Lesson 17 – The Internet and WorldWide Web (WWW)
Learning Objectives
1. To understand the concept of Internet and its components

2. To know about the capabilities of Internet and the benefits
3. To study the role of Internet in Information Management.
5. To know the role of managers as Internet Strategist
17.1 Introduction
A few years ago, the computer industry was bragging about 10 million people being
connected to the Internet. Now that figure exceeds an astonishing 100 million plus people in the
United States alone! The Internet is changing the way we work, play, entertain ourselves, and
communicate with people all over the world.
17.2 The Internet
The Internet was developed in 1969 for the U.S. military and eventually spread to universities
and civilian researchers. Because of its open structure, interest in its use began to grow beyond these
exclusive groups. In 1990 a scientist named Tim Berners-Lee created a software program that he
called the World Wide Web which allowed people to find documents on the Internet much more
easily. This program allowed for the use of hyperlinks, which connect one document to another. In
1991 commercial use of the Internet was permitted for the first time and that is when its use started to
explode. In 1994 the Netscape Communications Company (first named Mosaic) was formed by Marc
Andreeson and Jim Clark to market a new software application for the Web called a browser. This
graphical user interface allowed users to maneuver around the Web using a point-and-click method
instead of text commands.
The Internet is best described by what it isn't. There is:
• No single computer
• No single control source
• No single entry point
• No single type of application
The Internet consists of computers spread all over the world, connected through wired and wireless
transmission media, which contain software codes that allow them to talk to each other. That's it. If
you tried to find a single "front door" to the Internet, you'd be looking for a long, long time.
Small businesses and individuals connect to the Internet through Internet Service Providers (ISP)
such as AT&T World Net or a commercial online service provider such as Dishnet DSL. With recent
mergers in the entertainment and Internet industries, some users can now access the Internet through
their cable TV companies.
Internet Technology and Capabilities
As you can see from the following table, many services are available to you through an Internet
connection.

Major Internet Capabilities
Capability Functions Supported

E-Mail Person-to-person messaging; document sharing
Usenet newsgroups Discussion groups on electronic bulletin boards
LISTSERVs Discussion groups using e-mail mailing list servers
Chatting Interactive conversations
Telnet Log on to one computer system and do work on another
FTP Transfer files from computer to computer
Gophers Locate information using a hierarchy of menus
World Wide Web Retrieve, format, and display information (including text,
audio, graphics, and video) using hypertext links
TABLE 10.1
Email is the most widely used application on the Internet. America Online alone processes an average
of 51 million email messages per day, according to the CNet Web site, April 3, 1999. The text
explains the construction of an email address. What you need to remember is that the text input is
extremely sensitive, so you must be careful when you enter an address. The best way to cut down on
errors is to store addresses in an address book and use them instead of typing in an address every time.
If you make it a habit to use the Reply function when responding to an email, you also reduce the
chance for error.
In March 1999 a malicious virus called "Melissa" was sent throughout the world via email messages.
The Computer Emergency Response Team at Carnegie Mellon University called it one of the worst
viruses ever released. It created havoc with network servers and shut many of them down because of
the tremendous number of emails it generated. This incident demonstrated how pervasive email is and
yet how vulnerable it can be to hackers.
The most useful feature of email is the ability to attach files to an email message and send them to
colleagues anywhere in the world. This feature alone makes it a valuable tool for telecommuters and
for collaboration with co-workers wherever they may be located.
Information Retrieval on the Internet
We keep complaining about information overload, yet we crave more. The Internet provides access to
data about any topic you can imagine. Keep in mind that false information is as readily available as
true and correct information. Be careful about the source of the information you access.
Another useful technology for collaborative work is the File Transfer Protocol (FTP) application.
Many companies and individuals use FTP to share documents among geographic locations. It's a little
faster and easier than email, but you do need a special software program to use it. Some Web sites
offer FTP as a way to move files from a server computer to client computers.
You can get many free software programs for Internet use from various World Wide Web sites. They
are very good programs and are easily installed. In fact, many software production companies no
longer stock their programs in retail stores and offer them only through their Web sites. This
drastically reduces the cost of distribution, packaging and shipping, and allows the company to offer
the very latest editions of their programs. It's much more convenient for consumers too because they
can just download and install the programs right to their hard drive.
You can also use Web sites offered by software companies to download "patches" or additional
features. A patch is actually software code that fixes bugs in programs. An excellent example of how
convenient this process is demonstrated by the Melissa virus mentioned earlier. Within 48 hours after
the virus was discovered, many companies had patches to detect the virus or protect their system from
it available through their Web sites. If we were doing business the old-fashioned way, these patches

wouldn't have been available for weeks. But then some of you will say that if we had continued to do
business the old-fashioned way, we wouldn't have needed the patch in the first place!
When you purchase software now, either through a regular retail outlet or on a Web site, make sure
you register with the company, because this will allow it to send you email messages regarding new
products, improved products, or patches to existing products. You'll also be able to access its Web site
for free technical support. Yes, you do give up information when you send the registration in
electronically, but the advantages associated with the notifications and other services may be worth it.
Many computer companies have established Web sites that offer free and quick support for problems
you may be having with their products - either hardware or software. You don't have to spend hours
on the phone waiting for a person to answer. Most of the problems you have are probably common to
other users, and the Web sites are a better way for you to get help.
17.3 The World Wide Web
The World Wide Web is a vast repository of data and information connected through hyperlinks.
When you think about the fact that it didn't even exist ten years ago, it's amazing to realize how much
it has permeated everything we do in our personal and business lives.
We discussed protocols before: these are the rules by which data are transmitted over networks. The
Hypertext Transfer Protocol (http) is what allows the Web to operate. When you see a Universal
Resource Locator (URL) address on a Web site it will always start with http://www. Most software
browser programs now automatically insert the http for you so you can simply enter the URL address
of the Web site you want to access, beginning with the www.
Hypertext Markup Language (HTML) is the common language with which you create Web
documents. It is very easy to use and is now included in most common software applications such as
Word, WordPerfect, Excel, etc. As the technology improves to include audio, video, animated
graphics, and movies on Web sites, derivative languages such as Dynamic HTML, Java, and ActiveX
are becoming more common.
There is a difference between a Web site and a Web page. A Web site has the short domain address
such as www.prenhall.com. It is the central repository for many, many Web pages that will be
included at the end of the address after the domain name and a slash. For example,
www.prenhall.com/index.html is a Web page within the Web site for Prentice Hall. A Web page is a
single document stored within the Web site and probably linked to other pages on the site.
Webmasters, people who create and maintain Web sites, are in hot demand because of the limited
knowledge and experience most companies have with Web sites. Software application programs such
as FrontPage 98 or Macromedia Dreamweaver can help you set up and manage a Web site. You can
also use these programs to create single pages and store them on a Web host computer. Many Internet
service providers such as America Online and Web sites such as Geocities also give you the ability to
create and store your own Web page on their servers.
Which brings us to the matter of managing a Web site once you’ve created it? You should never
create a page or a site and then forget about it. You must constantly manage the information resource
and make sure that not only is the content current, but so are any hyperlinks you have with other
pages on your site or other outside sites. Many Web site managers make it a habit to change the site or
at least some pages on it monthly, weekly, or even daily, in order to keep it fresh. It's one way you can
keep people coming back to your site; they will know that something new has been added.
Searching for Information on the Web

The lesson gives you the basic information for using search engines and directories. You need to
understand and remember that the various search engines use different methods of helping you find
information on the Web. You shouldn't restrict yourself to just one or two search engines but should
try many different ones. You may be surprised at the different results you'll get using the same topic.
Search engines use special software programs to monitor the Web for new or updated sites or pages.
When they reach a new site or page they analyze the contents and determine the category in which it
will be listed. They then add it to their database so that it will appear on the search result list when
someone enters the appropriate subject. You can also search for FTP sites, Usenet, newswires,
business news, stock quotes, and weather using these search engine capabilities.
If you develop a site or page you can add your URL to the search engine so it will know your site is
available. Many search engines don't require you to do this since their software programs will
eventually find your site, but you can speed up the process by registering with the search engines.
Some innovative entrepreneurs have established businesses that will register your site with all the
search engines - over 400 of them - for a price. You can do it yourself with your time as your cost.
When you are searching for information, try using a search site which submits your inquiry to 25
different search engines and returns a complete list of the results. Dogpile.com is the most popular of
these services. If you type in a topic such as "horse breeding" on the Dogpile.com Web site, it will
submit the topic to popular search directories and engines such as Yahoo, Excite, Lycos, Infoseek, and
HotBot. You tell the search service how you want the contents listed and in what priority. It's much
easier and faster than visiting each search engine site yourself.
You also should be aware of the individual and business directories on the Web. You could call them
the "Yellow Pages of the World." They act just like the Yellow Pages of your telephone book. In fact,
most of the information listed in them is gathered from telephone directories. They are easy to use and
are cheaper than calling your phone company information service; they are free!
Web Portals
Portals are Web sites which serve as a starting point for you whenever you first enter the Web.
Portals can be set as the "home page" on your browser, the first page that appears when you open your
browser program. The most popular portal at the present time is Netscape Netcenter. This site receives
millions of hits per day. You can personalize a portal according to your preferences and get
individualized information about the weather, news, stock quotes, and even your daily horoscope.
Many also offer you free email accounts.
The Yahoo! portal site reports that it has 35 million registered users. Excite has 20 million. Lycos
reports 28 million. At its official launch on Jan. 12, Go Network claimed 9 million registered users.
So what's in it for the portal Web sites? If it's all free, how do they make any money and stay in
business? Well, it's free to you, but they make their money by selling advertising space for other
companies and by gathering information about you and selling it to other companies. Some portals get
a certain amount of money, maybe 10 cents, for every person who clicks from the portal site to an
advertiser's site. If that happens a few tens of thousands of times a day, every day, they can make a
tidy sum of money. They also give the services away hoping that you'll buy their other products.
Some of them simply operate in the red hoping to eventually make a profit.
17.4 Intranets and Extranets

Net this, Net that, it's almost enough to drive you crazy! Intranets and Extranets are basically the
same thing as the Internet and use the same operating methods. Intranets are restricted to the internal
members of an organization and Extranets are limited to certain users outside of an organization who
are given special access to the Web site. Access to Intranets and Extranets is controlled through the
use of usernames, and passwords, plus firewalls, security software programs that keep unauthorized
users out of the network.
The beauty of Intranets and Extranets is that they don't require any special software or hardware other
than what you would use for the Internet. The easy-to-use software programs to create Web sites and
pages give more people in an organization the ability to use these Nets for very creative purposes.
Using these 'Nets can drastically reduce the costs of disseminating information to employees,
customers, and suppliers.
Suppose you are the Human Resources Manager of a mid-size company and you are establishing a
new employee plan. Of course you need to get the information out to the employees as soon as
possible so they can sign up for the plan. Many of them will have questions and will want some help
computing the benefits of their enrollment. You can quickly and easily set up a Web page that
explains how to enroll and gives them an enrollment form right on the Web. You can have a
Frequently Asked Questions (FAQ) page employees can use to read what other people are asking and
also post their questions.
You can answer their questions on the FAQ page, which gives other employees the opportunity to see
the information. An especially useful tool would be to include an online calculator to compute
contributions and the rate of return on investments. Think of the time you and the other Human
Resource Office members will save if employees can do all that on their own and don't have to visit
your office.
Extranets are becoming very popular as a way for companies to get information to customers and
suppliers quickly and efficiently. It's much less costly to put the information on the Extranet and it's
faster to update the information than to have to print and send out paper updates. Some companies are
using Extranets to replace EDI systems. Smaller companies that couldn't afford the cost of EDI are
using Extranets as a way to allow online product ordering and shipment tracking.
17.5 Internet Benefits to Organizations
More and more individuals, organizations, and companies are turning to the Internet as an integral
company resource for information because of the widespread use and acceptance of the technology,
and because of the ease of use and relatively low cost. We can list down the benefits of using the
Internet as below.
• Connectivity and global reach

• Reduced communication costs
• Lower transaction costs
• Reduced agency costs
• Interactivity, flexibility, and customization
• Accelerated distribution of knowledge .2
To be sure, there are costs associated with using Net technologies. But can you imagine setting up
your own private network, which would have to be installed in all the other organizations you do
business with? You simply couldn't do it. But you can establish a network that is connected to the
Internet, which in turn is connected to the other networks.

The use of Intranets, Extranets, and the Internet is also proving to be the answer to many "road
warrior" prayers. They can quickly and easily connect to the home office to receive up-to-date
information about products, services, or internal company information. And they can do it from
airports, hotel rooms, their own homes, or the ski lifts at Vail. No other technology has ever given
companies and individuals so many options.
What started out to be the kingdom of the nerds is now used by millions of people for such things as
ordering prescriptions, garden plants, and even Tupperware. Your company or organization can now
reach millions of people in ways that were never before possible with reduced transaction costs.
The many uses of Intranet, Extranets, and the Internet, are limited only by your imagination! The Nets
are open 24 hours a day, seven days a week. The benefits of using these new technologies are a
blessing to many companies.
17.6 What Is an Internet Strategist?
An Internet Strategist is an underused yet much-needed part of any contemporary business.

Novell says an Internet Strategist “sets an organization's Internet direction through a thorough
understanding of Internet technology and its possible use in increasing productivity, expanding an
organization's marketing reach, and reducing customer support costs.” The American Electronics
Association calls an Internet Strategist a “marketing expert who can figure out how to handle
marketing in a still-evolving new medium.” I define an Internet Strategist as a Management
Information Systems specialist who can solve business problems using new information
technology. No matter how you slice it, any company hoping to survive in the new economy needs
someone who can best utilize technology. An Internet Strategist fills that role.
What an Internet Strategist Provides to Today’s Businesses
Changes in today’s technology present more of a challenge than figuring out how to share the
office calendar online. Clients, partners, and employees expect that a business will use technology as
a tool to its fullest extent in every situation. Doing so is possible in most environments, but it requires
two important components. First is an understanding of the extent of the technology’s reach. Second
is the talent to implement needed changes.
The Internet provides unlimited potential as a communication medium and as an application

platform. Some businesses enjoy the breadth of the Internet at their virtual doorstep, but most
struggle–spending far too much capital for far too little return. The presence of a strategic plan for
using the Internet as a business tool greatly enhances the return on investment. This plan is an
Internet Strategist’s domain.
Many IS managers read about the newest technology and then try to find a place in their
organization to implement it. An Internet Strategist starts with business problems and uses his or her
knowledge of existing technology to create timely and cost-effective solutions.
An educational research organization I know of that needed a remote application failed to hire
the services of an Internet Strategist. This organization’s “internet Application” ended up a VB 5
client server application with a database that replicated itself in six locations via expensive phone
lines. Only after it experienced a 22% failure rate and spent tens of thousands of rupees did the
organization engage an Internet Strategist.
Such failures are all too common in the Internet industry. The proliferation of tools like
Adobe Pagemill and Microsoft Frontpage lull business owners into a false sense of security about the
Internet’s perceived simplicity. Engaging a specialist who can translate business needs into Internet

languages often makes the difference between a successful project and a tremendous waste of capital
and manpower.
Complementary Roles of an Internet Strategist
An Internet Strategist interacts with the Marketing team, the Development staff, and the
Operations department. An Internet Strategist usually works with the decision makers in each
division, such as the Directors of Marketing, IS, and Operations. These positions aren’t titled the
same in every organization, but all organizations contain them. An Internet Strategist enjoys a
different relationship with each position.
The Director of Marketing is usually most interested in using the Internet to advertise, market,
or sell. Advertising shows potential new customers the product; marketing convinces prospects that
the product is what they want; selling consummates the deal with a customer. An Internet Strategist’s
place in these processes is to best utilize the company’s technology and the Internet’s opportunities to
build a system that will maximize profit potential. To do so, an Internet Strategist is primarily tasked
with reviewing marketing strategy while remaining mindful of both the possibilities and limitations of
the Internet medium. An Internet Strategist must be able to say, “You can’t do that,” but also must be
able to say, “You can do it this way, and it’s much cooler.”
Any Internet-related role is often associated heavily with a company’s Information Systems
division. In fact, the IS Director often fills the Internet Strategist role. When he or she does not,
however, the two players must communicate closely. Developing internal systems and using the
Internet in those systems are two remarkably similar tasks that require remarkably similar tactics.
Planning is at the core of this close relationship. Both positions require the ability to look out two or
even five years to create network strategies.
In general, an Internet Strategist does not own many processes within a company–with the
occasional exception of the corporate web presence and intranet–but he or she acts as a forum for
interaction between several business units. This function requires an unusual set of skills.
Skills Expected of an Internet Strategist
When working with Marketing, Operations, and Development, an Internet Strategist’s

greatest challenge is to translate between the specific languages each division of the business uses.
This is like having a communications graduate, an engineering graduate, and an MBA all rolled into
one employee. Marketing, Operations, and IS experience is mandatory, but the skills that
complement this experience are even more varied and unusual.
Business skills learned in school will include conceptual accounting, statistics and high math,
and technical writing and communication. Technical skills should focus on system and data design
and object-based methodology. Language doesn’t matter. Languages come and go on the Internet,
but good design lasts forever.
Practical skills vary even more. Real experience building web applications is a must. The
Internet Strategist is not a froo-froo management position. Hands-on, up-to-date knowledge of how
this all is done is an absolute requirement in order to best translate the needs of the business-side units
for the technology builders. This falls into one of two categories: Microsoft builders (InterDev,
Visual Basic, IIS, SQL Server, Windows NT) or Java builders (Java, JSP, OAS, Oracle, Solaris). The
ability to use the Internet in daily business–e-mail, web, file transfer tools, instant messaging,
streaming media–is another requirement of the same depth. Knowledge of the network layer also is
expected.

On the business side, writing is most important, followed by an understanding of the sales and
marketing processes. Other skills many have found helpful include statistical analysis, business
experience in several industries, PC skills (such as with Office), traveling experience, reading
comprehension, a firm grasp of several sales processes, and creative graphic arts.
An Internet Strategist uses management, engineering, and marketing skills and knowledge to
produce vital advice about the use of a tool that is growing so fast that Inc. Magazine says that four
months are like a year. Part of any vital company, not just technology companies, an Internet
Strategist provides the glue to hold together the IS, Marketing, and Operations sides of a business in
this rapidly changing world. An Internet Strategist can save your business. Don’t enter cyberspace
without one.

Lesson 18 – E-Business
Learning Objectives
1. To know about the role played by Internet and Intranets in E-commerce
2. To understand the supporting activities available for E-commerce
3. To study the concept and framework of E-business
4. To know the considerations in doing business through Internet.

18.1 Introduction
We have seen a lot about the benefits of networking and Internet in the earlier lessons. We
may conclude the real benefit of Internet as a resource being utilised for doing business globally. Let
us recall some of our understandings on Internet as follows. The Internet is a worldwide network of
computers joined together by telecommunication lines. It is a communications medium that allows us
to send electronic information between computers linked to this network. When we discuss the
Internet we are generally talking about applications on the Internet that let us send electronic
messages like e-mail or publish documents with images and text like the World Wide Web.
Increasingly the Internet has become a sales channel for many different types of goods and services. It
has been estimated that transactions worth $7.29 trillion will take place over the Internet by the year
2041.
E-Business refers to all business processes that take place across electronic networks. This
includes everything from buying and selling of goods and services through the World Wide Web, to
interactive television and a whole host of other emerging technologies. E-Business integrates
Information and Communication Technologies (ICT) with traditional business processes, introducing
efficiencies that cut costs and increase profits. Andrew Grove, the Intel Chairman, has predicted that:
"In a few years' time, there will be no Internet companies - there will just be companies - and
all companies that will operate in the future, will be Internet companies."
The key to successful E-Business is not to concentrate on the technology itself but to decide
the way forward for your business within this new environment. When you have decided how you
want to move your business forward then start to look at the technology solutions.
Let us see the role played by Internet in E-commerce in the following sections which will help us to
understand E-Business better.
18.2 The Internet and Electronic Commerce
Internet Business Models
The last thing you want to do is throw up a Web site or a Web page, include an email address,
and call it done! Regardless of the type of business, you have to determine what you're going to do
behind the scenes and how your electronic commerce efforts will fit in with your regular business
processes.
There is no simple step-by-step list of things you need to do to establish an E-commerce
process, no "one size fits all" method. But remember these facts:
• It's not cheap.
• It's not easy.
• It's not fast.
Some companies have spent millions of dollars only to fold up their E-commerce operations
because they just weren't working. Some companies have built a Web site without thinking through
the entire process; only to find out they have seriously hurt their normal operations. Some companies
have realized that E-commerce was simply not the Holy Grail it was made out to be.

You need to analyze what you want the mission of the Web site to be. Are you going to have
a Web site that simply offers information about your company and its products? Are you going to sell
only to consumers? What impact will that have on your current retail outlets? How are you going to
get people to your Web site in the first place? How are you going to keep them coming back? If you
sell business-to-business, do you have the back-end processes in place to handle the increased sales?
Who will host the Web site: your company internally? a Web host service? Who's going to create the
Web site, what services will you offer on it, and how are you going to keep your information secure?
We don't mean to discourage you from electronic commerce; just the opposite. Thousands of
businesses are finding new opportunities to connect to customers, suppliers, and employees.

TABLE 10.3
The above table shows some ways companies use the Internet to conduct business. Even more
intriguing is the disruption new, upstart companies are causing in traditional industries. MP3.com
introduced the Rio music appliance, which uses music downloaded for free from Web sites.
Recording companies are jumping through hoops trying to respond to this threat to their business. The
real lesson you should learn is that no business can afford to rest on its laurels and assume its business
or industry is safe from changes caused by the Internet.
Customer-Centered Retailing
Some of the most successful consumer E-commerce companies have found that it isn't enough
to set up a Web site to sell products: consumers want information about the products themselves and
how to integrate the products into their lives.
Amazon.com, probably the most talked-about consumer retail Web site, doesn't just sell books and
CDs. It also offers book reviews from other customers, links to other books related to the one they're
purchasing and the opportunity to purchase gifts for friends and relatives which are then gift-wrapped
and sent out. Amazon.com is moving into other markets such as online auctions and now owns part of
an online grocery shopping service.
Disintermediation, removing the middleman, has allowed many companies to improve
profits while reducing prices. Now we're starting to see a phenomenon called reintermediation, the
process of creating new middlemen. Many people are concerned about selling products online
because of the possibility of fraud.
Let's say you want to sell an antique car through your Web site. A stranger in Ohio emails you
with an offer of $10,000. You hesitate to seal the deal because you don't know anything about this
individual. You can use an electronic escrow service that will hold the buyer's funds to ensure he
receives the merchandise while you make sure you get paid. Online auction services such as
eBay.com offer a form of reintermediation through their Web sites to get buyers and sellers
connected. That's the great thing about the Internet: One door closes and another door opens!
Business-to-Business E-Commerce

When you think of Internet-based business, you probably think of businesses selling to
individual customers. It may surprise you to learn that business-to-business is the fastest growing area
of E-commerce and outpaces consumer retailing by millions of dollars.
The Internet allows many smaller companies to participate in government and private bids
they otherwise would be locked out of by bigger competitors. Governments and companies that let out
the bids are finding that they get lower bids through the Internet because of the increased number of
bidders.
Other companies are able to reduce costs by getting more competitive prices from a wider
range of suppliers. But you still have to make sure you know all the costs associated with this new
process. Let's say you've always gotten your office supplies from the store down the street. Suddenly
you discover a Web site that offers lower prices. So you fill up your shopping cart and purchase your
supplies from the Web site. But then you add in the shipping and handling costs. Did you really come
out ahead?
If you're the one selling the product, you should make sure your prices and extra costs are in
line with your competitor's. You also must make sure your company can handle the possible increase
in sales. All parts of your organization should be involved in supporting the E-commerce effort, not
just one or two departments.
One company, Asian Sources Online, has combined the two into Asia's largest electronic commerce
venture. "Asian Sources established a Web site to connect thousands of mostly small and medium-size
Asian exporters of everything from hardware, fashion and giftware to computers and electronic
components with big importers such as Kmart, Toys "R" us, Home Depot, Tandy Radio Shack and
Texas Instruments. A buyer sitting in, say, Chicago can pay virtual visits to factories all over Asia and
see products without leaving his office.
A buyer connects to the Asian Sources Web site, views products from over 4,000
manufacturers, orders the products, and arranges for shipment and payment. Of course the buyers
don't like the idea that they can't take a two-week business trip to the Orient any more, but that's
another story.
18.3 Electronic Commerce Support Systems
You don't have to go it alone. Many businesses use companies that supply all of the Web
support from designing and developing the Web site to actually storing the Web site pages (Web
hosting) on their servers. Some commercial companies also offer backend services such as credit card
transaction processing (electronic payment systems).

TABLE 10.5
Larger corporations can hire companies such as IBM to help them establish a Web presence.
One of the benefits of having your Web E-commerce outsourced is that you don't have to hire the
expertise in-house and you gain from the supplier’s experience with other E-commerce endeavors.
There are many considerations and decisions to make when you're developing E-commerce. It's not
easy, it's not cheap, and it's not quick. But done right, it can give you opportunities you never had
before.
18.4 Intranets and Electronic Business
Rather than create your own networking software from scratch, you can use Internet protocols
with their easy to use interfaces to put a front on your existing systems. You'll have to create a
software connection between the two, but often it's cheaper to do it this way than to start from scratch
to build a whole new Information System.
For instance, you use a database software system as your main information system to support
production and manufacturing. You have a second separate database software system that you use in
advertising and marketing. You can spend a lot of money to create one big database system that
combines the two, or you can build an interface that makes it appear as though the two are one.
How Intranets Support Electronic Business
• Connectivity: Accessible from most computing platforms

• Can be tied to legacy systems and core transaction databases
• Can create interactivity applications with text, audio, and video
• Scalable to larger or smaller computing platforms as requirements change
• Easy to use, universal Web browser interface
• Low start-up costs
• Richer, more responsive information environment
• Reduced information distribution costs
The two advantages that stand out are the low start-up costs, and the easy to use, universal Web
browser interface. Businesses can defray lots of the cost of establishing an Intranet because they don't
have to create the interface programs for users. The content can be created using simple, off-the-shelf
software programs. The company isn't limited to text; it can include audio and video files which
employees can use for training or communicating with distant colleagues and customers. Simply put,
the possibilities are endless.
Intranets are especially useful for allowing geographically separated collaborative teams to
work together. As long as you're careful to use firewalls to secure your Intranet from outside
interference, they are a cheaper, quicker method of sharing data and files among many workers. To be
sure, you still need face-to-face interaction, but you can get more work done cheaper this way.
A very nice feature of Intranets in organizations is their ability to connect different types of
computers with different operating systems. Let's say that one department has a base of Apple
computers and just loves the way they work. Another department has PCs that it refuses to give up.
Yet another department uses a closed mainframe system for its computing needs. It's virtually
impossible to get all the different platforms talking to one another except through the use of Intranets.
Now it doesn't matter what type of computer hardware or operating system is being used: they can all
communicate through Web sites. The company doesn't have to buy new hardware, and the software
cost is restricted to a browser application.

Intranet Applications for Electronic Business
FIGURE 10.8
This figure gives you an idea of how your business can incorporate an Intranet to improve your
functional applications.
Coordination and Supply Chain Management
FIGURE 10.9
An Intranet can drastically reduce an organization's supply chain costs and management
through improved coordination between various departments. It's possible that the production and
shipping departments are located in one building, and the engineering department is located across
town. The engineers can waste a lot of time traveling back and forth across town or simply fail to
coordinate with production altogether. An Intranet offers much improved coordination between these
departments.
Outside suppliers have an advantage if they have access to the company's Intranet because
they stay up-to-date on the latest design changes. They can also process deliveries easier and faster by
having access to information that communicates the company's needs.

There are so many innovative uses of Intranets in business today it's hard to say just how far
we're going with this technology. As user expertise grows and the technology becomes more
common, Intranets will replace many traditional processes at lower cost and increased ease of use.
18. 5 Defining E-Business
Electronic-business or e-business can be defined as the organized effort of individuals to

produce and sell, for a profit, the products and services that satisfy society’s needs through the
facilities available on the Internet. E-commerce is a part of e-business and is the term used to refer
only to the buying and selling activities online including when a firm uses the Internet to identify
suppliers, select products or services, make purchase commitments, complete financial transactions,
and obtain service.
Organizing e-Business Resources
Besides the conventional organization of human, material, informational, and financial

resources needed to conduct business, e-business requires several specialized resources in order for a
firm to participate on the Internet.
1. Human resources, in the form of people who can design, create, and maintain web sites,
are only a fraction of the specialized talents required by businesses considering an
Internet presence.
2. Material resources must also include specialized computers, equipment, software, and
high-speed Internet connection lines.
3. Informational resources, generally in the form of reporting software that focuses on
tracking the efficiency of the web site operations and offers insight into how satisfied
customers are interacting with the firm’s web site, are needed.
4. Financial resources, the money required to start, maintain, and allow the firm to grow,
usually reflect greater participation by individual entrepreneurs and venture capitalists,
instead of conventional financial sources such as banks
Satisfying Needs Online.
Customer needs that are satisfied by Internet firms are often unique to the Internet
environment or are an improvement over conventional business practices. For example, AOL
provides Internet access, browser services, chat rooms, databases, and exclusive Time Warner
entertainment content among other services to its customers. The Internet provides the opportunity
for interaction. Communication is now an active two-way street between the online program and the
viewer. The Internet allows customers to specify the content they are offered. Knowing what is of
interest to an individual customer allows an Internet firm to direct appropriate advertising to that
customer.
Creating e-Business Profit
Firms can increase their profits by either increasing sales revenue or reducing expenses
through a variety of e-business activities.
• Revenue Growth. A fundamental concern for online firms is how to select, develop, and
nurture sources of revenues. Each source of revenue flowing into the firm is referred to
metaphorically as a revenue stream.
• Expense Reduction. Expense reduction is the other major way in which e-business can help
increase profitability. Providing online access to information customers can reduce the cost of
dealing with customers.
18.6 A Framework For Understanding E-Business

A. The Internet was originally conceived as an elaborate military communications network that
would allow vital messages to be transmitted in the event of war.
• New technology emerged that simplified use of the Internet and allowed the addition
of multimedia content. This multimedia environment of audio, visual, and text data
came to be known as the World Wide Web or the web.
• The Internet can be envisioned as a large network of computers connected by cables
and satellites, which pass small, standardized packets of electronic data along from
one station to another until they are delivered to their final destination.
• To transfer a variety of multimedia data around the world, data need to be digitized,
which means converted to a type of signal that the computers and telecommunications
equipment that make up the Internet can understand.
• Most firms involved in e-business fall more or less into one of the three primary
groups as defined by their e-business activities: telecommunications and computer
hardware manufacturers and Internet service providers; Internet software producers;
and online sellers and content providers.
B. Telecommunications and Computer Hardware Manufacturers and Internet Service
Providers
• The telecommunications and computer hardware manufacturers that helped build the
Internet, together with Internet service providers, supply the physical infrastructure of
the industry today.
• Internet service providers (ISPs), which buy their technological capability from the
makers of telecommunications hardware, provide customers with the necessary
technology to connect to the Internet.
• AOL is the largest and best-known ISP, but hundreds of smaller ISPs in both urban
and rural areas also provide access to the Internet.
C. Internet Software Producers. The second primary group of e-business firms that have
emerged since the beginning of commercial activity on the Internet comprise the software
producers who provide the functional capability to do things on the Internet. Activities such
as searching the Internet, browsing web sites, sending e-mail messages, shopping online, and
viewing multimedia content all require specialized software programs that allow computers to
function the way they do on the Internet.
D. Online Sellers and Content Providers. The third primary group of e-business firms is made
up of all the firms that customers actually interact with on web sites. The Internet would still
be limited to communication between individuals and special interest groups of researchers if
it was not for the activity of sellers and content producers of products and services that
populate the Internet.
E. Global e-Business. All three primary groups of e-business firms are in a race to capture
global business revenues that are only now just emerging.
F. Small e-Business. Although global-scale firms dominate e-business, the remarkable thing
about the Internet is how accessible it is to small businesses. The relatively low barrier cost of
entry to the Internet means that the door is open to thousands of small businesses seeking
opportunities for growth internationally In some cases, small firms have found a niche service
or product to sell online.
Social and Legal Concerns
The social and legal environmental concerns for an e-business extend beyond those shared by
all businesses. Businesspeople must deal with the special circumstances of operating in a new frontier
without borders or much in the way of government or other organizational control or regulation. For
better or worse, the world of e-business is an emerging industry with great opportunities for customers
and businesses but with equally great concerns about behaviors.

Ethics and Social Responsibility. Socially responsible and ethical behavior by both individuals and
businesses on the Internet is a major concern, which has simply extended from the general social
environment to the special virtual environment of cyberspace. The opportunity to commit unethical or
even illegal behavior is a primary factor in determining whether that behavior will be committed.
Unfortunately, the Internet provides a shelter of anonymity and detachment for both individuals as
well as firms, which might suggest why certain behaviors have surfaced.
Security Concerns. For all intents and purposes, the Internet is an unregulated frontier in business.
As such, both individuals and business users must be aware of the risks and dangers as well as the
benefits and opportunities to be found online such as viruses and breech of privacy.
Government Regulation. For the most part, government regulators view the Internet as just an
extension of regular business activity of firms operating in their jurisdiction. The rules and regulations
apply to all businesses whether they exist entirely or only partially online. Taxes must be charged and
sales of controlled products like pharmaceuticals must follow the law.
18.7 The Future of E-Business: Growth, Opportunities, and Challenges
Since the advent of commercial activity on the Internet, developments in e-business have been
rapid and formidable. Forrester Research, Inc., a Cambridge, Massachusetts, research firm, predicts
that global Internet commerce will soar to $6.8 trillion of trade by the year 2004, up substantially from
earlier attempts to estimate growth. Although most of this activity will remain a North American
phenomenon, growth is expected to explode in some Asian-Pacific and Western European countries.
Measurements of Growth. Measurements of e-business growth not only illustrate the magnitude and
scope of how much has happened in just a few short years but also indicate trends for the future.
• More than 61 percent of U.S. home Internet users go online every day–often several times
a day–compared with 57 percent in 1998 and 46 percent in 1997.
• Home users spent an average of 7.2 hours a week online, about the same as 1998,
indicating home users have found a stable amount of time to allocate to Internet activities.
• Men still outnumber women slightly, but the growth in the number of women users has
risen steadily. In 1997 only 16.5 percent of women were online and, by late 1999, that
figure was up to 49 percent.
• The average Internet user’s age has risen steadily as well, to 40 years, up from 38.6 years
in 1997.
• The number of Internet users making purchases online nearly doubled between 1998 and
1999, going from 27 million to 52 million.
• According to a Neilsen / NetRatings survey, 130 million people can access the Internet
from home, and some 80 million did in April 2000.
• In comparison to the home market, 35 million users had access to the Internet at their
places of work, and nearly 31 million of them actively used the Internet. Both groups of
users spent about thirty minutes per session and viewed an average of thirty-five pages.
The primary difference between these groups was in the number of sessions per month,
where those at work connected an average of thirty-eight times per month, twice the
number of those at home.
• Global Internet users spent an average of 7.6 hours online in March 2000, up from 7.17
average hours per month in January 2000. The most time was spent by Internet users from
the United States and Canada with a combined average of nearly thirteen hours per visitor
per month, while users in Europe spent on average just over five hours on the Internet in
March.
Convergence of Technologies. The phenomenon of overlapping capabilities and the merging of

products and services into one fully integrated interactive system is referred to as the convergence of
technologies. We can expect to see this tendency to help develop interactive television programs,
which will allow viewers to pause, or even select, a preferred direction for a program.

Online Communities. Online communities, which are made up of groups of individuals as well as
firms who in some way wish to exchange information, products, or services over the Internet are
likely to grow.
Partnering Online. Although opportunities will continue to exist for independent e-business effort,
much success will continue to come from firms that can cooperate and partner with others. By playing
a partial role within a larger entity, smaller firms can enjoy competitive advantage, access to
marketable items, and thereby increase their rate of market penetration.
18.8 Summary
You are a part of the most revolutionary time in business. Many companies are struggling
with all the changes and trying desperately to comprehend their role in the new world. You can help
yourself and your organization tremendously by understanding the issues involved and developing
innovative strategies to resolve the problems.

provide? What do they charge? How long have they been in business? What technologies do
they use (for example, SOAP or XML)?

UNIT III
Lesson 19 – Tutorial on E-Business
In this lecture, let us discuss cases out of which we will get thorough understanding of the benefits of
Internet and the other Technologies used by the firms in their business.
Cases
Package Delivery
The secret to being a successful package delivery company is timeliness, efficiency, and
affordability. In the last 30 years, guaranteed two-day and overnight delivery has made drastic
changes in businesses' perceptions of timely. Pony Express delivered messages for several years, until
the telegraph rendered it obsolete. Many thought that fax machines and e-mail would do the same
thing to the overnight market. So far this has not been the case. The industry has continued to change
nonetheless, hastened by the march of technology, a new set of customer needs, and a change in the
way business is conducted:
Manufacturers and sellers had previously focused on reducing shipping costs and time to customers in
a more competitive marketplace. The current marketplace now demands speed to market in order to
reduce product cycle times. Many high-tech products are becoming obsolete in record times and the
there is a need to provide fast-cycle logistics. Doing so adds enormous value to customers by
compressing production and delivery cycles, particularly for time-sensitive products such as IT com-
ponents, biotechnology and pharmaceutical products, or medical devices. Furthermore, it allows
companies to reduce the carrying costs and lower their inventories levels
Efficiency is also a critical element in the delivery industry. Companies in other industries are
increasingly relying on UPS and FedEx to handle many common delivery tasks. Through efficiency,
these companies can provide delivery services follower costs than the other companies can match.
Financial Analysis
While moderate to high market growth continues in the industry, prices have declined because
of fierce competition. Technological advances and efficiencies have enabled the industry to contin-
ually cut costs. United Parcel Service (UPS) and Federal Express (FedEx), the two most
technologically advanced companies, have reported profit increases greater than yearly sales increases
Stock/Investment Outlook
The stock projection for the package delivery industry is positive for the next few years. Most
of the large delivery companies are rated a buy or outperform for the next three to four years
Growth Potential
The package industry has shifted from providing delivery services to becoming integrators of
customers' supply chain systems. FedEx and UPS have assisted companies with supply chain
management by offering tools and consulting, and handling international shipment from end to end.
One of the major areas for improvement that the package delivery must meet, particularly for express
carriers, is that of free movement of packages through customs in order to meet global business
demands for overnight delivery. Julian Oliver, the director general of the International Express
Carriers Conference had the following figures to offer on the express carrier industry [Oliver]

• 200 countries being serviced

• 650,000 people employed
• 1,200 aircraft
• 1,350 daily flights 175,000 trucks and vehicles
• 20 million daily shipments $50 billion in .duties and taxes
In his presentation Oliver also points out that outside industry sources such as Boeing and Airbus
predict prolonged growth in the industry. Both airline manufacturers predict double-digit growth rates
for next 15 years for airfreight. According to estimates from the Colography Group, the global value
of air-shipped goods approached $2.2 trillion in 2000, increasing by almost 7 percent over 1999. As in
the United States, the express segment of international shipping is also growing twice as fast as the
broad market in terms of tonnage, Globalization, just-in-time logistics, customized mass production,
rapid customer response, and e-commerce, along with other trends, all point to greater use of parcel
service in the future,
Market Share Competitive Structure
The U.S. market is made up of seven large companies, dozens of smaller entities, and the U.S.
post office. The biggest shakeup in the package delivery industry occurred when UPS, the sleeping
giant, awoke. For years, UPS was the industry cash cow. It owned the package delivery market and
was a very staid company trying to do one thing well-mass-produced delivery. After the upstart
FedEx began the new overnight market, UPS slowly began to transform itself to expand into that and
other markets. One of the ways UPS transformed itself was to increase the marketing department from
7 to 600 people, in order to attract and keep corporate customers
Given the high cost of entry, the oligopoly in the marketplace will continue. Billions are
needed to develop facilities in trucking, delivery, computer, and air networks. These costs keep new
companies from entering or becoming a dominant force in the marketplace. As time goes on, more
buyouts, mergers, and alliances may further restrict the number of players.
Role of Research/Development
The role of research and development in the package delivery industry is to develop new
technologies that will cut the cost of shipping, shorten delivery times, provide better services to cus-
tomers, and integrate the supply chain between supplier and customer in order to reduce product cycle
times. Wireless technologies and robust, Web-based applications that are accessible to customers, are
key technologies and services that are being offered to customers today. Most of the focus lies in
improving efficiency through distribution and planning. The use of mobile computers and
transponders, as well as satellites, to monitor packages and vehicles is also increasing shipping
efficiency. Other high-tech applications are on the horizon. One is an IT tool that allows shippers and
intermodal operators to simulate flows of cargo, detect inefficiencies in combined transport op-
erations, and search for alternative transportation scenarios.
Technological Investment and Analysis
FedEx and UPS are leading the industry in technological spending. They are attempting to
integrate all facets of the delivery process so companies can eventually outsource their supply chain
management to them. Eventually these delivery companies want to become the supply chain
managers for corporations. Once FedEx and UPS have introduced their services into customers'
routines, it is more difficult and troublesome for customers to switch to other delivery services
Assets that provide the means to move goods physically are undifferentiated and generically
available to all players. Technology has emerged as the method to distinguish a company's products,

improve its service quality, and lower costs. As such, it has become increasingly important to
manufacturers and sellers to be able to access real-time information about the status of parts,
materials, and finished goods in a world of just-intime inventory management. Furthermore,
integration with suppliers' networks would provide a more accurate picture for managers to decide on
production issues
Recommendation for the Future
New economy dynamics have transformed the supply chain. Forced by the reality of
competition, firms can no longer manage production, inventory control, transport, and sell and service
as functions independent of one another. The new economy supply chain is an entirely different
animal, defined by its organic nature, whereby operational impacts of any part of the organism are
keenly felt throughout the entire supply chain. Firms that want to compete and excel in the new econ-
omy need to integrate demand, management, inventory management, distribution, and customer
fulfillment with seamless information flows from the supplier level to the production level, and on to
the customer level in real time. Each of the supply chain components must be supported by
sophisticated information systems that provide the highest degree of visibility, precision, and
efficiency. This is particularly true for companies engaged in electronic commerce
Case: Federal Express
There was no such industry as express delivery of packages until FedEx started it in 1973.
Not only did it create an industry, but it has also set the standard against which competitors are
measured. With annual revenues of $20 billion, FedEx Corp. is the premier global provider of
transportation, e-commerce, and supply-chain management services. In order to gain a greater market,
FedEx has expanded from its express delivery services to complete integrated business solutions
through a network of subsidiaries operating independently, including FedEx Express, the world's
largest express transportation company; FedEx Ground, North America's second largest provider of
small-package ground delivery service; FedEx Freight, a leading provider of regional less-than-
truckload freight services; FedEx Custom Critical, the world's largest provider of expedited, time-
critical shipments; and FedEx Trade Networks, a provider of customs brokerage, consulting,
information technology, and trade facilitation solutions. FedEx has grown from being a solely
overnight express package delivery service to a complete supply-chain management provider for any
type of business need.
Technological Investment and Analysis
Despite the economic slowdown, FedEx has continued to invest in its IT infrastructure with a
proposed $1.5 billion IT budget for 2002, unchanged from its 200 I IT budget. There are
approximately 2.2 million unique visitors to the website each month. Approximately 69 million
packages delivered by FedEx Express every month are either processed or prepared for delivery
online. [Chen 2001] FedEx's website was the first to allow customers to track their shipments online
and to also ship them.
While customer-interfacing technologies keep customers coming back, it is in back-end

systems where the Internet has made the most impact at FedEx. FedEx offers multiple methods for
customers to connect to its shipping, tracking, and logistics systems over leased lines, direct
connections, private networks, and ED! (Electronic data interchange). Now the company is actively
pushing large and small customers alike onto the Internet through the use of XML. Today, the
majorities of large corporate customers continue to use private networks and leased lines to connect to
FedEx's systems. But Robert Carter, executive vice president and CIO at FedEx, said he is optimistic
that more and more blue-chip companies will begin to transact with FedEx using the Web and XML.
Technological Innovations

In 2002, FedEx launched online document completion to its customers that need to ship
internationally. FedEx wants to enable its customers to complete documents online, therefore al-
lowing them to export to more than 20 countries by completing the forms online and sending them
directly to the appropriate customs officers over the Internet. The company currently provides
customs forms that must be printed, filled out, and sent to customs by the customer
Additionally FedEx's IT department began testing a number of additional wireless

technologies, including Bluetooth on courier devices, which allow carriers to communicate in short -
range with their offices. The technology upgrade provides FedEx Ground customers with the fastest
signature proof of delivery and adds to the most detailed package-tracking information in the ground
shipping market [Transport News 2001] The company has also begun to wire its offices with WiFi
wireless LANs that enable development groups to collaborate wirelessly in conference room~ All of
this is an effort to provide the latest technology to customers and help them become even more
efficient
Recommendation for the Future
FedEx should integrate as many tools to allow their customers to run their shipping
departments if they wish to do so. However, FedEx has also recognized that there is a greater value to
the customer in becoming involved in the many areas of supply-chain management in order to reduce
product cycle times. This will allow major -customers to concentrate on their core business and
outsource the supply chain management aspect to FedEx. Furthermore, this move will allow FedEx to
diversify and become a long-term partner of the company therefore ensuring future cash flows.

Case: United Parcel Service
United Parcel Service (UPS), the world's largest package-delivery company, provides specialized
transportation services through the pick-up and delivery of packages, primarily by air and ground
transportation in the United States, as well as various logistics services. UPS is the leader in its
industry for delivering 55 percent of merchandise sold online compared with FedEx's 10 percent,
according to consultancy the Sageza Group Inc. The company, founded in 1907, now handles over 3
billion packages and documents per year and delivers to every address in the United States and in
more than 200 countries and territories. Sales in FY 2000 totaled $29.771 billion, up 10.1 percent
year-over-year.
New facilities in Georgia and New Jersey house what UPS claims is the largest database in

the world, the DB2 database. The DB2 database has more than 7,000 gigabytes of records, the
tracking information regarding all UPS packages shipped in an 18-month period. This kind of
computing power translates into information regarding senders, receivers, billing, bar codes, time
sent, estimated destinations, a:i1d other information for more than 4 billion packages.
The new Atlanta site is primarily backup for the New Jersey operations in case of disaster or
expansion needs. Input into these new centralized computing facilities is through DIADs, or delivery
information acquisition devices specially developed for UPS by Motorola. These devices are handheld
by the delivery person and feature 1.5 MB of RAM; digital signature capability, and an optical
coupler. The optical 'coupler is used to transfer information and signatures into the DVA or DIAD
Vehicle Adapter, where data is then transferred via cellular phone or modem. UPSnet makes the
transfer of data to the data facilities in New Jersey and Atlanta. UPSnet does this via a network of
500,000 miles of dedicated cables, more than 200 switching nodes, and a UPS satellite
Outsourcings of certain functions needing expert advice and creating partnerships that support
the needs of information systems are also underway. For example, to send all the information from the
delivery trucks through the DV A using UPS TotalTrack, UPS has alliances with more than 90 local
and regional cellular carriers including AT&T Wireless Communications, AirTouch Cellular,
Southwestern Bell Mobile Systems, Pacific Telesis, GTE Mobilnet, and others. Northern Telecom
switches provision UPSnet's dedicated cables directly linked to the central computing facilities.
Several types of products from several companies result in a I 00 percent up time for the network.
Users of UPS MaxiTrac dial through lines provided by AT&T and Sprint. For data
warehousing, UPS has chosen EMC Corp. and a system developed by Hewlett-Packard Co. and
Oracle Corp. UPS's existing mainframes were not meeting the speed and availability needs required to
service the vast amounts of data, but with the help of EMC, data warehousing will now be state of the
art. These cooperative agreements have helped lessen UPS's technology-related-responsibilities and
have focused UPS's energies on more core issues
The final implementation of UPS's technological initiative is the development and upgrading
of software application products. One of the results of this initiative is UPS Online. This service is a
Windows-based system that lets customers manage finances related to the package, track the status of
their package, and print out shipping summaries. This system will integrate UPS into the customers'
daily operations while providing more valuable information, allowing the customer to react situations
in real time.
Another new product is the UPS website. On the site, a browser can find information about
the company, what is new in the company, employment information, news releases, and a host of
other information related to UPS. The customer can also find on the site a service that will, using bar
codes, locate where the package is in the delivery process. In this way, even the casual, non company-
related customer could have access to most of the information that users of UPS Online would have.
If all goes as planned, the Internet and the UPS website will also serve as a center where transactions
will occur without the security hazards still present on the Web. The Internet potential is great and
UPS wants to be one of the first companies capitalizing on its potential
Another new product is the improved help desk that will service both internal users as well as
external users in an attempt to "empower our [employees and customers] to become as Independent as
possible in using technology." The help desk function was not a formal organization five years ago,
but as the volume and the sophistication of UPS and its software grew, and as the need for support for
these new technologies grew, an operation was launched to service the need.
With the internal and external operations combined, the help desk receives approximately
70,000 calls a month, a dramatic increase compared to approximately 14,000 calls a month in 1991.
The external operation is run by 130 front-line experts and the internal group is run by 65 first-line

consultants in the Mahwah, New Jersey, campus
The intimidating task of supporting all the software at UPS is, in turn, supported by
Windows-based Expert Advisor from the Software Artistry Company. Previously, the help desk
function was supported by IBM's mainframe based Infoman, but its limitations became too apparent
as the move to PC-based operations from mainframe operations came about
Expert Advisor allows UPS to store more data online to assist helpers solve problems in a
standardized manner quickly and efficiently. The help desk technicians no longer have to flip through
binders full of information to solve an issue. Rather, they just have to type it into Expert Advisor.
With its dynamic ability to constantly update and incorporate new diagnostic tools and solutions into
the system, Expert Advisor has developed the help desk function into a real value-adding arm at UPS
UPS has therefore taken steps to initiate and seek new technologies as well as react to
industry forces. These technologies all have an element of risk involved as significant funds have
been allocated for the acquisition of new equipment, new software, and new employees. However, it
is clear that UPS is trying to innovate to keep its market share and profitability
In an interesting twist, UPS acquired Mail Boxes Etc (MBE) in April 2001. MBE is the
world's largest franchiser of local shipping centers. The transaction essentially gives UPS several
thousand new customer counters, along with revenue from mail box rentals. More important, UPS ex-
tended its operations in the international area by purchasing Fritz Companies, which specializes in
logistics, freight forwarding, and customs brokerage. In 2001, UPS also acquired First International
Bancorp, which specializes in structuring international transactions. [Quarterly report]
Technological Innovations
Telecommunications
In 1998, UPS launched an Internet-based delivery service that the company says could make
life a lot easier for firms wanting to send sensitive documents on tight deadlines. The service is called
UPS Document Exchange. It is a suite of delivery and information management services that provides
a choice of two Internet delivery services: UPS OnLine Courier and UPS OnLine Dossier
UPS OnLine Courier uses either the UPS website or a separate software package and allows
customers to send documents to anyone, regardless of the e-mail software package, operating system,
or hardware being used on either side of the delivery process. UPS OnLine Courier is built on an open
environment.
"It has a PDF (portable document format) and Adobe PDF built into it, so if the recipient
doesn't have the same software as you do, it won't hinder their ability to read it. That's a benefit of the'
Courier," said Joan Schnorbus, a UPS spokesperson. [Press release]
UPS OnLine Dossier takes UPS OnLine Courier a step further by using a double-encryption
process and offering insurance. The document will self-destruct if tampered with. UPS OnLine
Dossier authenticates identities using digital certificates, which are required by both sender and
receiver
UPS is developing another service for corporate customers. This service integrates UPS
package-tracking capabilities directly with the customers' websites. The move allows consumers to
obtain tracking information for their orders from the site where they ordered rather than by jumping to

UPS
The Internet
Increasingly, UPS (and FedEx) are relying on the Internet to provide additional service to
customers. For example, tracking packages through the company website is faster and substantially
cheaper than the 800-number service using operators. For the 2001 holiday season, UPS extended the
use of the Internet by offering a Web-based return service. Customers wishing to return a product
simply click on a link to print a return shipping label. The service costs only. 75 cents per transaction
plus the shipping cost-making it substantially cheaper than other methods that require the help of a
real person

UNIT IV
Lesson 20 – Transaction Processing System (TPS)
Learning Objectives
1. To understand the various types of Transactions and concepts of TPS

2. To study the characteristics and features of TPS
3. To learn the process of Transaction Processing
4. To know the applications of TPS.
20.1 Introduction
Whenever two people make an exchange, it is called a transaction. Transactions are important
events for a company, and collecting data about them is called transaction processing. Examples of
transactions include making a purchase at a store, withdrawing money from a checking account,
making a payment to creditor, or paying an employee.
Because transactions generally involve an exchange of money, it is critical that the data be
protected during transmission and stored carefully so that it cannot be altered. It is also critical that the
data be saved so that managers can verify the data if any conflicts arise. Also, the sales and purchase
data from the foundation of the accounting and financial systems of every company, so the system
must be able to produce the standard reports.
Let us look at an example of real-world TPS. CareNet, the TPS of Travelers Insurance
Company, is an advanced system that records and processes insurance-related transactions. Filing and
processing insurance claims is a highly information-intensive process in which every step generates
new data or modifies existing data. CareNet allows the company to accurately capture this data and
disseminate it at the right time to its 7 million clients. The information generated by CareNet is useful
both to employees of Travelers Insurance and to its clients. A Travelers employee can access the
system and look at the latest transaction; an authorized client can also access CareNet to study the
status of his or her insurance claim. This system, therefore, spans organizational boundaries and
provides information to both internal external entities.
So when we are talking about the transactions of an organization in computerized manner, we
talk about Transaction Processing System, popularly known as TPS
20.2 Transaction processing systems: Meaning
Transaction processing systems were among the earliest computerized systems. Their primary
purpose is to record, process, validate, and store transactions that take place in the various functional
areas/of a business for future retrieval and use. A transaction processing system (TPS) is an infor-
mation system that records company transactions (a transaction is defined as an exchange between
two or more business entities).
Transaction processing systems (TPS) are cross-functional information systems that process
data resulting from the occurrence of business transactions.
Transactions are events that occur as part of doing business, such as sales, purchases,
deposits, withdrawals, refunds, and payments. Transaction processing activities are needed to capture
and process data, or the operations of a business would grind to a halt.
Let us look at a simple example of a business transaction. McDonald's, which sells a large
number of hamburgers every day, orders raw materials from its suppliers. Each time the company
places an order with a supplier, a transaction occurs and a transaction system records relevant
information, such as the supplier's name, address, and credit rating, the kind and quantity of items
purchased, and the invoice amount.

20.3 Types of Transactions

Note that the transactions can be internal or external.
When a department orders office supplies from the purchasing department, an internal
transaction occurs, when a customer places an order for a product, an external transaction occurs.
• Internal Transactions: Those transactions, which are internal to the company and are related
with the internal working of any organization. For example Recruitment Policy, Promotion
Policy, Production policy etc
• External Transactions: Those transactions, which are external to the organization and are
related with the external sources, are regarded as External Transaction. For example sales,
purchase etc.
20.4 Characteristics of Transaction Processing Systems
1. A TPS records internal and external transactions for a company. It is a repository of data that
is frequently accessed by other systems
2. A TPS performs routine, repetitive tasks. It is mostly used by lower-level managers to make
operational decisions
3. Transactions can be recorded in batch mode or online. In batch mode, the files are updated
periodically; in online mode, each transaction is recorded as it occurs.
4. There are six steps in processing a transaction. They are data entry, data validation, data pro-
cessing and revalidation, storage, - output generation, and query support.
20.5 Features of TPS
1. A TPS supports different tasks by imposing a set of rules and guidelines that specify how to
record, process, and store a given transaction. There are many uses of transaction processing
systems in our everyday lives, such as when we make a purchase at retail store, deposit or
withdraw money at a bank, or register for classes at a university. Almost all organizations, re-
gardless of the industry in which they operate, have a manual or automated TPS
2. A TPS is the data life-line for a company because it is the source of data for other information
systems, such as MIS and DSS (Decision Support Systems). Hence, if the TPS shuts down,
the consequences can be serious for the organization
3. A TPS is also the main link between the organization and external entities, such as customers
suppliers, distributors, and regulatory agencies
4. TPS exist for the various functional areas in an organization, such as finance, accounting,
manufacturing, production, human resources, marketing quality control, engineering, and
research and development. Until a few years ago, many companies viewed the TPS for each
business function as separate entity with little or no connection to other systems in the
company. Today, however, many companies are trying to build cross-functional TPS to
promote the free exchange of information among different business units. This is a desirable
goal, but is still very difficult to achieve
20.6 Process of Transaction Processing System
The six steps in processing a transaction are:
a. Data entry
b. Data Capture
c. Data validation
d. Processing and revalidation

e. Storage
f. Output generation
g. Query support
To be processed, transaction data must first be entered into the system. There are a number of
input devices for entering data, including the keyboard and the mouse. Documents generated at the
point where a transaction occurs are called source documents and become input data for the system
For example, when a customer returns an item at a store, the sales receipt becomes the source
document for the transaction "return item for refund". An ATM receipt for a bank transaction be-
comes.
a. Data Entry
To be processed, transaction data must first be entered into the system. There are a number of
input devices for entering data, including the keyboard and the mouse. Documents generated at the
point where a transaction occurs are called source documents and become input data for the system.
For example, when a customer returns an item at a store, the sales receipt becomes the source
document for the transaction "return item for refund". An ATM receipt for a bank transaction
becomes
The use of automated methods of data entry is known as source data automation. Several
methods have been developed to accomplish this automation, though very few completely automate
the data entry process. They are all based on trying to reduce or eliminate many of the activities,
people and data media required by traditional data entry methods
Methods for Data Entry:
• Keyboard/video display terminals

• Optical character recognition (OCR) devices, such as optical scanning wands and grocery
check-out scanners.
• Magnetic ink character recognition (MICR) devices, such as MICR reader/sorters used in
banking for check
• Other technologies, including electronic mice, light pens, magnetic stripe cards, voice
input, and tactile. Input also be used as input device depending upon the application
requirement
b. Data Capture
We could capture transaction data as close as possible to the source that generates the data.
Salespersons capture data that rarely changes by prerecording it on machine-readable media, or by
storing it on the computer system.
Tips for Data Capturing
• Capture data by using machine-readable media initially (bar-coded and magnetic stripe
credit cards), instead of preparing written source documents
• Captures data directly without the use of data media by optical scanning of bar codes
printed on product packaging. It ensures the accuracy and reliability of data by comparing
c. Data Validation
There are two steps in validation: error detection and error correction, Error detection is
performed by one set of control mechanisms, error correction is performed by another
Some commonly used error detection procedures are checking the data for appropriate font
(text, numbers, etc), checking for aberrations (values that are too low or too high), and checking for

missing data, invalid data, and inconsistent data. Missing data refers to fields that are missing a
mandated data value.
For example, if the number of hours worked by a part-time employee is missing on a payroll
form; that is a missing-data error.
Invalid data is data that is outside the range
For example, if the number of hours worked by a part-time employee is 72 hours per week
instead of the 1120 hours, then we have invalid data
Inconsistent data means that the same data item assumes different values in different places
without a valid reason.
For example, if payroll records show that an employee worked 25 hours per day.
d. Processing and Revalidation
One the accuracy and reliability of the data are validated, the data are ready for processing.
There are two ways to process the transactions: online and bath mode
Following methods are available for Data Processing:
• Online transaction processing (OLTP) is the almost instantaneous processing of data. The
term online means that the input device is directly linked to the TPS and therefore the data are
processed as soon as. it is entered into the system. Input device may be at a remote location
and be linked to the system by networks or by telecommunications systems. Some examples
of online transaction processing are ATM transactions, student registration for classes. The
processing of flight reservations is another good example of an online system in which data
are processed
Process /
Transactions Enter Directly Update Master Master File
File
A travel agent checks for seat availability, using the data in a central computer system, and
lately notifies the customer as to the status of his or her ticket. Once the reservation is made,
the airline system updates its files and sends a confirmation to the travel agent. Online
'processing is possible because of storage, such as disks, that process data in a random order.
• Batch Processing, in which transactions are accumulated over time and processed identically.
Batch processing may be done on a daily, weekly, or monthly basis or any other time period
appropriate to the application. For example, a company may process the travel expenses of its
employees on a monthly basis, whereas Bath processing usually involves. Gathering source
documents originated by business transactions, such as sales orders and invoices, into groups
called batches. Recording transaction data on an input medium, such as magnetic disks or
magnetic tape. Sorting the transactions in a transaction file in the same sequence as the
records in a sequential master file.

Update
A transaction file contains information about a group of transactions that occurred in a given
period of time. It is processed using techniques such as sorting, merging, and so on. Once the
transaction file has been processed, the next step is to update the master file, which is
permanent record of all transactions that have occurred. Each time the master file is updated
with information from the transaction file, a new master file, including most current
transaction data, is generated.
Although until the early 1960s batch processing was the only method for processing data,
today there are other methods, However, batch processing continues to be a popular method
because it is often the most sensible and practical approach, For example, batch processing
lends itself well to payroll operations, since paychecks are generated periodically. Processing
jobs in batches also results in more efficient use of computer resources. Finally, quality
control is sometimes easier in batch processing, since errors detected at the end of a batch can
be rectified before the next batch is processed.
e. Data Storage
Processed data must be carefully and properly stored for future use. Data storage is a critical
consideration-for many organizations because the value and usefulness of data diminish if data are not
properly stored. The kind of processing and the type o(storage medium are, to some extent, related
issues. For example, magnetic tape is often used to store data that is Batch-processed. However,
online transaction processing cannot be done. on magnetic tape; it relies on other types of storage
media, such as magnetic disks
The next step in the processing of a transaction is to output the results of the transaction to the
decision maker. Note that storage and output may not always occur in the same order. We can output
the results 0f the transaction to the decision maker and then store them, or store the result and then
output them to the decision maker.
f. Output Generation
Once data has been input, validated, processed, revalidated and stored, the output can be
communicated to decision makers in two ways:
• Documents and reports
• Forms: screens or panels.
Documents are a popular output method. They can be processed further, either to generate
additional information or to present the same information in a different format. Some examples of
documents are invoices, paychecks, purchase, invoices., sales receipts, and job orders
What is the difference between documents and reports? A document is usually a record of one
transaction, whereas a report is a summary of two or more transactions. For example, the manager of
a retail store may receive an invoice (i.e., a document) from a supplier indicating the quantity and type
of each item ordered and the total cost of the ore::;'. A report, on the other hand, may summarize all

the invoices from a given supplier. (Nevertheless, these terms are often used interchangeably)
Computer output need not always be presented in hard-copy form (such as reports,
documents, and printouts), but can also appear on computer screens and panels. Such soft-copy
presentations are known as forms
g. Query Support
The last step in processing a transaction is querying (asking questions of) the system. Query
facilities allow users to process data and information that may otherwise not be readily available. For
example, a sales manager may query the system 'f the number of damaged items in a given store
Many transaction processing systems allow you to use the Internet, intranets, extranets, and
web browsers or database management query languages to make inquiries and receive responses
concerning the results of transaction processing activity. Typically, responses are displayed in a
variety of pre-specified formats or screens. Examples of queries include:
• Checking on the status of a sales order
• Checking on the balance in an account
• Checking on the amount of stock in inventory
20.7 Summary
Every organisation must perform certain basic operations: pay employees, pay bills, monitor
revenue, and file government reports. Operations are relatively structured, short-term, and easy to
computerize. They form the foundation of the company. TPS support operations by collecting data
and helping to control the underlying processes.
Transaction processing systems are responsible for capturing, storing, and providing access to
the basic data of the organisation. The goal is to capture the transaction data as soon as possible.
Common collection methods include point-of sale services, process control, electronic data
interchange, and electronic commerce websites. Because data is the foundation for all other decisions,
TPS must maintain data integrity and minimise the threats to the data.
Points to Ponder
Transactions Are In ...

Communications:
Each time you make a phone call, there is a call

setup transaction that allocates some resources to
your conversation; the call teardown is a second
transaction, freeing those resources. The call setup
increasingly involves complex algorithms to find the
callee (800 numbers could be anywhere in the world)
and to decide who is to be billed (800 and 900
numbers have complex billing). The system must
deal with features like call forwarding, call waiting,
and voice mail. After the call teardown, billing may
involve many phone companies.

Finance:
Each time you purchase gas using a credit

card, the point-of-sale terminal connects to the
credit card company's computer. In case that
fails, it may alternatively try to debit the amount
to your account by connecting to your bank.
This generalizes to all kinds of point-of-sale
terminals such as cash registers, ATMs, etc.
When banks balance their accounts with each
other (electronic fund transfer), they use
transactions for reliability and recoverability.

Travel:
Making reservations for a trip requires many related

bookings and ticket purchases from airlines, hotels,
rental car companies, and so on.
From the perspective of the customer, the whole trip
package is one purchase. From the perspective of the
multiple systems involved, many transactions are
executed: One per airline reservation (at least), one for
each hotel reservation, one for each car rental, one for
each ticket to be printed, on for setting up the bill, etc.
Along the way, each inquiry that may not have resulted
in a reservation is a transaction, too.

scheduling, accounting, and so on are classical
application areas of transaction processing.
Computer integrated manufacturing (CIM) is a
key technique for improving industrial
productivity and efficiency. Just-in-time
inventory control, automated warehouses, and
robotic assembly lines each require a reliable
data storage system to represent the factory
state.

Real-Time Systems:
This application area includes all kinds of physical

machinery that needs to interact with the real world,
either as a sensor, or as an actor. Traditionally, such
systems were custom made for each individual plant,
starting from the hardware. The usual reason for that
was that 20 years ago off-the-shelf systems could not
guarantee real-time behavior that is critical in these
applications. This has changed, and so has the
feasibility of building entire systems from scratch.
Standard software is now used to ensure that the
application will be portable.

Review Questions
1. Define transaction and explain the different types of transactions in any business.
2. Explain the concept of Transaction Processing System and its importance.
3. List down the characteristics and features of TPS.
4. Explain in detail about the Transaction Processing Cycle / Stages.
Because of the importance of transactions, there is a large number of cases involving fraud
and other legal problems with sales and other transactions. Pick an industry and find articles
in business and trade journals that identify problems of this nature. How will computerisation
of the transactions affect fraudulent transactions? Why would the computerisation make it
easier or harder to detect these problems?

Visit at least three retail stores in your area and determine how they handle transaction
processing for sales. How many checkout counters are available at each store? By counting
the number of customers in a 10 to 15 minutes time interval, estimate the total number of
sales transaction occurring for a given day.

UNIT IV
Lesson 21 – Tactical and Strategic Level Information Systems
Learning Objectives
• To have a better understanding about the various Information Systems at the managerial and
strategic level of any organisation
• To know about the various functional information systems at managerial level.
• To identify the components and the benefits of operational level systems.
• To know about the support extended by these systems in Management Decisions
21.1 Introduction
As you move up the organizational ladder from supervisory positions to middle- and upper-
management positions, you will make decisions that have an increasingly greater impact on the
organization. The decisions you may face along the way are diverse and could include decisions similar to
these:
1. Should you purchase a new piece of equipment or lease the equipment for a three-year
period?
2. Is the idle cash of your firm being invested wisely?
3. Should you invest money in new computer equipment or in additional merchandise for
resale?
4. What criteria will you use to create territories for your salespeople and how large of a
territory should each salesperson cover?
5. What products should be emphasized through advertising or promotion to reach the firm's
sales goals?
6. What are the best potential sites for a new retail store location?
7. How many and what types of workers will be needed to staff a new plant in another state?
This lesson examines the types of tactical and strategic decisions that you may make as you move up the
ranks of middle and upper management. Specifically, we examine the application of information
technology to some of the tactical and strategic information systems frequently used by middle and upper
management in four organizational functions: accounting/finance, marketing, production, and human
resource management.
21.2 The Nature of Tactical and Strategic Information Systems
Tactical information systems support management decision making by providing managers with
regular summary reports, regular exception reports, ad hoc reports, and other information that helps them
(1) control their areas of responsibility and (2) allocate their resources to pursue organization goals. While
the focus of operational information systems is on the completion of tasks, the focus of tactical
information systems is on resource allocation; that is, how do you allocate the resources available to you
to reach organizational goals.

In contrast, strategic-level information systems are goal oriented. That is, these systems are
designed to support organizational goal and direction setting.

It is difficult at times to categorize some information systems as dearly tactical or dearly strategic.
For example, some marketing information systems, such as marketing research systems and competitor
tracking information systems, dearly could support both tactical and strategic planning decision-making.
Sometimes the decision to categorize a decision as tactical or strategic comes down to the length of time
the decision is likely to impact an organization. That is, decisions that will impact an organization for a
year or less are often viewed as tactical, while decisions that will impact an organization for more than a
year are often viewed as strategic.
The computerization of financial accounting systems changed the way managers viewed
accounting information. A large database of information became available in computerized form, and it
could be viewed or manipulated much more easily than data in traditional hard copy form. So managers
began to view this information as a resource for tactical planning. Suddenly managers could obtain
important summaries and comparisons of financial accounting data easily and swiftly. In the past this
information would have taken a great deal of time to extract from a manual financial accounting system.
The result was that managers began to view the financial accounting system as more than merely a
transaction-processing system, a producer of checks, invoices, and statements. It became a repository of
important data that assists management in tactical decision-making and long-range strategic planning.
21.3 Tactical Accounting and Financial Information Systems

Budgeting Systems permits managers to track actual revenues and expenses and compare these amounts
to expected revenues and expenses. It also allows managers to compare current budget amounts to those
of prior fiscal periods, other divisions, other departments-even to industry-wide data. Comparisons of
budget data against such standards allow managers to assess how they use their resources to achieve their
goals. For example, a manager may view the budget to find the amount of money actually spent in the
purchasing department on supervisory versus clerical staff. The manager may then compare those
amounts to the amounts spent by other purchasing departments in the organization or in the industry.
For example, the general ledger system of a financial accounting system may provide these
reports:
1. Current budget allocations, expenditures, and variances by budget line item.

2. Current budget allocations compared to the previous year's allocations.
3. Current revenues and expenditures compared to the previous year's revenues and expenditures.
4. Current revenues and expenditures compared to the average of the other units or divisions of the
organization.
5. Projected expenditures and variances for each budget line item for the entire year based on the
expenditures incurred to date.
Regularly produced tactical-level reports, such as budget variance reports, often generate
managerial questions and concerns. These in turn may lead managers to query the financial accounting
database for answers or solutions. Suppose, for example, that you are an accounting manager and
supervise several departments, including the billing department. Suppose further that the regular budget
report shows that the wages line of the billing department report is much higher than in prior years. To
find out why, you might query the financial accounting database for answers. If the database stores the
number of statements produced each month, the number of employees in the billing department, and the
costs associated with the billing department, you might obtain various measures of the productivity of that
department, such as the average number of statements produced per billing department employee and the
average cost per statement. If you found poor productivity results, you might then examine the
productivity of each billing supervisor compared to the average for the organization or the productivity of
each billing clerk compared to the average for the department. This information might lead you to
decisions about changing supervisory personnel, providing training for specific billing clerks, acquiring
new equipment to produce customer statements, or other possible remedies. Notice that the system does
not make the decisions for you; it provides information to help you identify and remedy problems. It is a
decision-support system, not a decision system.
Cash Management Systems
A cash flow report shows the estimated amount of cash that will be received and spent each
month. The report shows which months will have excess funds that might be put to use and which months
will have insufficient funds, which may require the organization to borrow cash to meet its working
capital or fixed asset acquisition needs.
Cash management systems are more difficult 'to sustain for smaller organizations that may not
be able to afford the resources necessary to track cash balances on a day-to-day basis and invest the
excess to maximize organization income. Recognizing that difficulty, Merrill Lynch, a brokerage house,
created a product in the 1970s that offered business customers an account combining the attributes of a
money market account, a brokerage account, a margin credit account, and a checking account. The
product, called the cash management account (CMA) provided business customers with automatic

deposits of cash and dividends from other accounts into a money market account. This option gave
organization high interest rates on idle cash resulting from sales of stock, receipts of dividends, or
deposits made for the purchase of stock. Organizations could also use a debit card and checks to withdraw
money from the money market account. The result was that a small organization could use the service to
maximize its income from idle cash sometimes available in its normal cash flow.
Capital Budgeting Systems
A capital budget contains information about the planned acquisition or disposal of major plant assets
during the current year. The manager may compare the various capital spending plans using three
commonly used evaluation tools: net present value, internal rate of return, and payback period. Before the
plant asset is acquired, the manager should compare and evaluate various plans for its acquisition using
some financial software tool, such as an electronic spreadsheet.
For example, suppose a manager is considering acquiring a large electronic printer and estimates
that her firm will keep the machine for five years. The printer may be purchased or leased. Each method
requires the manager to spend different amounts of money over different periods of time. The manager
can improve the decision to buy or lease by evaluating the present value of the funds each method
requires.
Investment Management Systems
Investment management-overseeing the organization's investments in stocks, bonds, and other

securities-is an important part of cash management. Managing investments is also an important part of
managing the organization's pension plan. Whatever their source of investment funds, most organizations
invest money in securities of one kind or another. Careful management of these investments is necessary
to ensure the achievement of organization goals.
21.4 Strategic Accounting and Financial Information Systems
Strategic accounting and financial information systems typically include several type of information
flows:
1. Internally generated financial condition analysis data, describing the status of the organization.
2. Externally generated economic, demographic, and social data describing the present and future
environments for the organization.
3. Forecasts of the future of that organization in those environments.
Two major outcomes of financial strategic planning are the setting of financial goals and directions of
the organization. The former may include setting goals for investments and return on investments. The
latter may involve deciding on new investment opportunities or on the mix of capital sources used to fund
the organization.
A major source of computerized information about the current and future Status of the organization is
the organization's own financial accounting database. A major source of computerized information on the
present and future environments in which the organization must operate are on-line databases that contain
economic, special, demographic, technological, and political information. Projecting likely scenario for
the organization using these two categories of data is the art of forecasting. Its’ major purpose of strategic

decision making is to use long-range forecasts to reduce the risk involved in major organizational
decisions.
Financial Condition Analysis Systems
Computerized accounting systems provide the user with many reports to which conditions and analysis
tools may be applied. For example, the manager may use a variety, analysis tools, on the data reported on
the income statement and balance sheet. Many computerized accounting systems supp reports that
automatically calculate and present the results of these tools and ratio Along with the data and reports,
these tools and ratios make up the organization financial condition analysis system. This system
provides management with variety of measures of the soundness of the organization and makes it possible
to explore ways of improving the organizations financial condition.
Commonly used financial ratios

RATIO NAME RATIO FORMULA
Current ratio Current assets ÷ current liabilities
Working Capital Current assets - current liabilities
Inventory turnover Cost of goods sold ÷ average inventory
Debt-to-equity ratio Stockholder equity ÷ total liabilities
Rate earned on stockholder’s equity Net income ÷ average stockholder’s equity
Earnings per share Net income ÷ number of shares
Long-Range Forecasting Systems
Strategic planners demand forecasts on a variety of factors that will affect organization performance in
the future. Some forecasts may involve the use of internally generated data. For example, past sales data
may be used to project future sales. Other forecasts may use only external data or both internal and
external data. For example, forecasting economic indicators helps planners understand the likely
economic environment in which the organization must operate in the future. Forecasting the financial
health of the organization through long-range budget estimates-including a variety of possible wage
negotiation settlements, actions by competitors, interest rate fluctuations, fuel cost changes, and different
inflation rates-provides planners with opportunities to consider actions that will help the organization
survive bad times or take advantage of a future environment.
Information used in forecasting the future environment includes descriptions of the past activities
of an organization, data on the present economy and forecasts of the future economy, information on the
present demographic structure of the region or country and forecasts of the future demographic structure,
and descriptions of the current social structure and social mores and predictions of the future structure of
society and societal mores.
21.5 Tactical Marketing Information Systems
As you learned, the marketing function is the satisfaction of the needs and wants of customers-
current and potential. Marketing managers engage in many planning activities in the pursuit of the
marketing function. These planning activities result in a combination of products, services, advertising,
promotion, price, and product delivery methods ultimately offered to the organization's customers, which
is referred to as the marketing mix.

Tactical marketing information systems differ from operational marketing information systems
because in addition to producing information on a regular basis, they also generate ad hoc reports, create
unexpected as well as expected output, produce comparative as well as descriptive information, provide
summary information as opposed to detailed data, include both internal and external data sources, and
process subjective as well as objective data.
A great deal of the data that tactical marketing information systems utilize is collected by
operational financial information systems. Tactical marketing information systems often combine
operational-level financial data with other data to support tactical decision making by marketing
managers. Tactical decisions are often made by managers when they prepare and implement marketing
plans through which they hope to reach top management's sales and profit
A major objective of marketing managers is to reach the sales goals set by top management. To
accomplish this objective, marketing managers must make many tactical decisions, such as how sales
territories should be shaped, how the sales force should be allocated within those territories, and what
emphasis should be placed in the products offered and customers served. Marketing managers must
decide ho to reward salespeople to encourage increased sales efforts, which market segment should be
emphasized to best reach sales goals, and which products and service will best appeal to each segment.
They also must monitor the progress of the sales effort to determine if their decisions were correct or if
they need to change the tactical plans.

Sales Management Systems
Sales management systems enable marketing managers to assess the productivity of the sales
force; the fertileness of sales territories; and the success of products by salesperson, territory, and
customer type. Sales management systems keep track of salesperson call activities, sales orders, and
customer activity. The systems allow the manager to identify weak territories or weak products in a
territory; to compare salesperson performance by product and customer type; to compare salesperson
performance against salesperson goals; to analyze salesperson calls within territories or by customer type;
to identify trends in customer purchases; to identify potential shortages or excess stock in inventory; and
to perform other planning, controlling, and organizing tasks with ease and speed.
Advertising and Promotion Systems
Marketing managers also need to develop advertising and promotional tactics to implement
strategic sales goals set by top management. Managers must decide which advertising media and
promotional devices to use to reach the selected market segments, when to use these media and devices,
and what overall mix of promotional activities to deploy to achieve sales goals. Advertising and
promotion systems assist managers in these tasks.
Pricing Systems
Pricing systems provide information to managers that helps them set prices for their products and
services. These information systems are important because the price of a product or service affects the
sales volume and profitability of the organization. The marketing manager usually selects a price that will
recover production costs and provide a profit, but the price chosen in constrained by the prices of com-
petitors for similar products or services and for alternative products or services. To make pricing
decisions, the marketing manager should know the expected demand for the product or similar products,
the desired profit margin for the organization, the costs of producing the product or providing the service,
and the prices of competing as well as substitute products. Substitute products refer to products that might
be used instead of the original product, particularly when that product is viewed as too expensive by the
customer. For example, a person might drive to a destination if the price of an airline ticket is viewed as
too expensive.
Distribution Channel Systems
To support the marketing manager, the marketing information system should provide distribution
channel decision-support systems. These systems should provide information on the costs of using the
various distribution channels, the time lags caused by the various channels, the reliability of the various

channels in delivering the products and services, and the market segment situation provided by the
channels. The systems should also track the demand and inventory at all levels of the distribution
channels so that the manager may anticipate excess inventories and shortfalls.
Competitive Tracking Systems
To ensure that your organisation’s marketing mix will continue to satisfy customers, you must
keep abreast of major competitors and their activities. In the end, market share is likely to be greatest for
the organisation that provides the marketing mix most closely matching a given market segment’s needs
and wants. Competitive Intelligence, or knowledge of the competitor prices, products, sales, advertising,
and promotions, must be gathered if the organisation is to avoid falling behind the competition in the eyes
of the customers. Gathering competitive intelligence is carried out through competitive tracking systems.
It should be noted that data about competitors can be used both tactically and strategically by managers.
21. 6 Strategic Marketing Information Systems
To develop an overall marketing plan, an organization may engage in a variety of tactical and
strategic planning activities (see Figure 11-8). The strategic activities may include segmenting the market
into target groups of potential customers based on common characteristics, needs, or wants; selecting
those market segments the organization wishes to reach; planning products and services to meet those.
customers' needs; and forecasting sales for the market segments and products. The tactical activities have
already been described and include planning the marketing mix-the best combination of product, price,
advertising, promotion, financing, and distribution channels to reach the chosen target groups. The
strategic activities revolving around sales forecasting and product planning decision making will now be
discussed.
Sales Forecasting Systems
Strategic sales forecasting systems usually include several varieties of forecasts: forecasts of sales
for the industry as a whole, forecasts of sales for the entire organization, forecasts of sales for each
product or service, forecasts of sales for a new product or service, and forecasts for market segments. The
results of these .sales forecasts are often further categorized by sales territory and sales division.
Regardless of type, sales forecasts are usually based on more than historical data; they are not merely
projections of past trends. Sales forecasts are also based on assumptions about the activities of the
competition, governmental action, shifting customer demand, economic trends, demographic trends, and a
variety of other pertinent factors, including even the weather.
Marketing Research Systems
In large organizations, research departments conduct and manage marketing research. In smaller
companies, marketing research may be completed by outside consultants or by personnel who must wear
several hats. Regardless of how the function is completed, the results of marketing research provide
important input to both tactical and strategic decision making.
These following activities are typical of a marketing research department.

1. Conducting trend analyses of industry sales of products and services identical or
similar to those offered by the organization to identify products or services that are on the
ascent or descent.
2. Analyzing population and target group characteristics, especially for trends or changes in data
that could affect the organization.

3. Analyzing and identifying consumer preferences, including testing products and services.
4. Determining and analyzing customer satisfaction with the organization's existing products
and services.
5. Estimating market share for all of each product and service offered.
Product planning and development systems
The major objective of product planning and development systems is to make information
about consumer preferences obtained from the marketing research system and from customer inquiries
available for the development of new products. The primary output of planning and development
activities is a set of product specifications. In a manufacturing organization, these specifications would be
given to the engineering department, which would try to design a product to. meet them. Similar activities
occur in service organizations. For example, a survey Of bank .customers may indicate that customers
would like a checking account that also acts like a savings account-an account in which they could place
all their money, maximize the amount of cash earning interest, avoid multiple statements, and avoid the
need to shift funds between savings and checking accounts. Bank personnel charged with product
development may then identify specifications for such a product that meet current banking laws and
regulations. These specifications may require the new account to carry the same rate of interest as a
passbook savings account, earn interest on the average balance on deposit during a month, not limit the
number of deposits or withdrawals during a month, maintain a minimum balance of $500, and pay
interest monthly. The specifications can be tested and refined through additional consumer surveys and
focus groups or through testing the product in a subset of the market, such as one branch of the bank.
21.7 Tactical Production Information Systems
Production systems encompass all the activities necessary to ensure the manufacture of products
or services. To perform its functions, the production system must locate production sites, plan the layout
of those sites, and produce a production plan. '{he production system has to acquire the raw materials,
parts, and subassemblies needed to produce the products or services described in the plan and to identify
how many workers of each type are required. The system must then allocate or acquire workers with the
appropriate skills, make certain that sufficient work space and production equipment are available, and
schedule an integrated use of these resources to produce the correct quantity of goods at \he correct time
to meet the marketing system's forecasted needs. While production is under way, the system also must
monitor the use and cost of those resources.
Materials Requirements Planning Systems
Inventory management can be taken a step further so that the system automatic produces
purchases orders for stock that needs to be reordered. Materials requirement planning (MRP) software is
basically a set of programs that use data from master production schedule, inventory files, and bill-of-
materials systems-or list raw materials and components needed to create each product-to help manage
production and inventory.
MRP systems perform a great deal of calculation and record keeping. When (quantities of raw
materials and parts are large, the calculations and record keeping become too time-consuming to complete
manually, except at high costs. The computer, however, has made such calculations and purchase-order
preparation possible for all of organizations, and in recent years, software to implement materials requires
planning has become abundant.
Just-in-Time Systems

The just-In-time (JIT) system is not tactical information system, but a tactical approach to
production. The just-in-time approach was created by the Toyota Motor Company of Japan and has
generated many advantages to organizations, especially those that do repetitive production. The purpose
of the approach is to eliminate waste in the use of equipment, parts, space, workers' time, and materials,
including the resources devoted to inventories. The basic philosophy of JIT is that operations should
occur just when they are required to maintain the production schedule. To assure a smooth flow of
operations in that environment, sources of problems must be eradicated. That means that quality must be
emphasized because quality problems interfere with the even flow of work. For inventory management,
JIT translates into having just as much inventory on hand as is absolutely needed, which is achieved by
developing efficient and effective production controls.
Capacity Planning Systems
In addition to ensuring that enough raw materials will be on hand for planned production, the'
production manager must also see to it that enough production capacity will be available to meet
production' goals. The purpose of capacity planning is to make certain that sufficient personnel, space,
machines, and other production facilities are available at the right time to meet the organization's planned
production. Managers also utilize capacity planning to minimize excess production capacity.
Capacity planning decisions are tactical production decisions and include allocating personnel
and production facilities. Selecting sites for constructing plant facilities, acquiring plant facilities, and
planning those facilities to meet long-term production goals are usually categorized as strategic planning
production decisions.
Production Scheduling Systems
The purpose of the production schedule is to allocate the use of specific production facilities for
the production of finished goods to meet the master production schedule. To manage the scheduling
process, a number of scheduling tools have been developed. Two of these tools are Gantt and PERT
(Program Evaluation and Reporting Technique) charts.
These tools allow managers to control projects and project completion times and also to
determine the impact problems will have on project completion dates. For example, top management may
ask a manager to complete a project sooner than originally planned. The manager may then consider ways
to shorten the duration of the project by completing two tasks at once. However, to complete two tasks
concurrently may raise production costs substantially, because two production teams and two production
facilities may be needed. To solve the problem, the manager may create what-if scenarios with the project
conditions using the PERT chart tool. However, Product Design and development Systems completing
multiple PERT charts manually requires extensive calculations and may prove frustrating to the manager.
Computer-generated PERT charts let the manager simulate many scenarios with speed and ease. The use
of 'project management software for this purpose is discussed later in this chapter.
Product Design and Development Systems
Many tactical decisions must be made to design and develop a product, especially a new product.
The design engineering team usually depends on product specification information derived from customer
surveys, target population analysis, or other marketing research systems.
The primary objective of the design .engineering team is to develop a product that meets perceived needs
of customer. However, the team's tactical task is to achieve that objective with the least demand on

company resources. Designing products to contain or reduce costs often results in ingenious uses of raw
materials, labor, and machinery. Through careful design, an engineering team can often design a product
that can be produced at lower costs than competitors can produce it. Careful design may also lead to a
simpler product, which leads in turn to fewer maintenance problems, better customer acceptance, fewer
product returns, and increased product repeat sales. Through the use of product design and development
systems, the . engineering team may provide the company with important competitive advantages.
Manufacturing Resource Planning Systems
More recently, software that provides for manufacturing resource planning (MRP-II) has become
available. MRP-II software extends the production information system to finance, marketing, human
resource management, and other organizational functions. A fully developed MRP-II system includes
modules that provide material requirements planning, shop-floor control, inventory management, and
capacity planning. The system also accesses cost accounting data through integration with the financial
accounting system. MRP-II systems usually accept data from a wide range of shop-floor data collection
equipment, including voice recognition equipment, factory robots, production-line sensors, process
control systems, bar code readers, and CAD workstations.
Computer-Integrated Manufacturing Systems -
Many production professionals envision a day when factory and product planning control, design,
and operation will be totally integrated and almost totally computerized. Some software and hardware
firms that provide MSP, MRP, MRP-II, CAD, CAM, CAI CAT, CAPp, CAl, robotics, and related
information systems are joining forces through mergers, acquisitions, and joint projects to integrate
current production hardware an software products into systems that provide computer-integrated
manufacturing (CIM), A growing number of manufacturers are utilizing CIM -or at least a great mar
components of CIM-to run their factories. Implementing CIM can lead to considerable cost savings,
improvement in quality, and more flexible responses to customer.
21.8 Strategic Production Information Systems

Strategic production information systems provide support for top-management-Ie1 production decisions
such as:
• Selecting a plant site.

• Constructing a plant addition.
• Building a new plant.

• Designing and laying out a production facility.
• Choosing the technologies that will be used in the production processes.
• Choosing responsibility for production processes-deciding basic policies on vertical
integration and outsourcing.
Decisions of this magnitude require the commitment of a large amount of capital and other resources
over a long period of time and thus are strategic in nature. Clearly, such decisions must not be made
lightly.
Site Planning and Selection Systems
Site planning systems usually rely on a variety of internal and external sources. Some of the
external information needed is relatively objective and quantitative, such as the availability and cost of
trained or experienced labor and the degree to which it is unionized, the availability and cost of

transportation for raw materials and finished goods, the availability of suitable sites, the cost of land, the
proximity of raw materials suppliers and finished goods customers, the availability and costs of power,
and the rate of property and income taxation.
Technology Planning and Assessment Systems
Having access to information on new; production technologies allows top management to make
better and more informed decisions about which production technologies to use for a product or service.
Technology assessment systems, which identify new technologies and assess them for their strategic
advantage, can help top management in many areas, not merely production. Like site planning,
technology information systems may include CD-ROM databases, traditional library resources, Internet
sites, and on-line databases maintained by government agencies, industry groups, private research groups,
and consulting organizations. They may also include technology assessment groups within the production
or engineering arms of the organization.
Process Positioning Systems
An important part of any organization's strategic production plan is the span of production
processes it decides to perform for any given product or product line. Decisions of this nature are called
process positioning, or vertical integration. An organization might purchase raw materials, fabricate
parts, assemble; parts into subassemblies, and then assemble and test the complete product. It may, on the
other hand, decide to purchase already constructed subassemblies and parts from others and limit its
internal span of production processes to assembling and testing the plant Design Systems completed
product. Outsourcing subassemblies, for example, to production facilities in third world countries, may
allow the organization to gain a competitive advantage by being a low-cost leader for its products.
Plant Design Systems
Designing and laying out a manufacturing plant requires large amounts of diverse information
about the proposed plant, including engineering data on the proposed site, proposed production
technologies, the number and duties of plant personnel, the expected schedule for the use of the facility,
the area transportation system, choices of water and power systems and their costs, the cost and
availability of construction materials, the plans for shop-floor information systems, and the need for
physical security. Much of this information is available to the plant design system from the site planning,
technology assessment, and process positioning decision processes.
21.9 Tactical Human Resource Information Systems
To assist managers in managing human resources, a number of information systems, called

human resource information systems (HRIS), have been developed (see Figure 11-1). Human resource
information systems contain personal information about the employees of an organization, and securing
this information against unwanted or unwarranted access, use, or distribution is terribly important to the
individuals involved. Unwarranted access, use, or distribution is also likely to be illegal under current
legislation and can subject the organization to serious legal liability. Security issues surrounding
databases, such as the human resource information database and the computer systems that house these
databases, are discussed in greater detail in Chapter 17. Human resource information systems include a
number of tactical and strategic information systems. Tactical HRIS include job analysis and design,
recruitment, training and development, and employee compensation. Strategic HRIS include information
systems that support workforce planning and labor negotiation.

Jon Analysis and Design Systems
Job analysis and design includes describing the jobs needed in an organization and the qualities of
the workers needed to fill those jobs. These tasks involve the development of job descriptions for every
type of position in an organization. Each job description specifies the purposes, tasks, duties, and
responsibilities of each job and the conditions and performance standards under which those duties and
responsibilities must be carried out. Job analysis and design also includes the development of job specifi-
cations for each type of job. A job specification describes the skills, knowledge, experience, and other
personal characteristics required to perform the jobs that are listed in job descriptions. In short, job
descriptions describe the jobs, and job specifications describe the workers needed to fill those jobs.
Recruiting Systems
A recruiting system should provide the organization with a bank of qualified applicants from
which it may fill vacant positions identified through the position control system and described by the job
analysis and design information system. The recruiting function should also ensure that the organization
is in compliance with various federal, state, and local statutes and contract regulations for affirmative
action and equal employment opportunity.
Compensation and Benefits Systems
To help human resource managers control their compensation and benefit plans, organizations
must keep and maintain information describing the various pay plans and fringe benefits as well as the
choices of each employee. The compensation and benefits system may support a variety of tactical
human resource decisions, especially when compensation and benefits information is related to
information from internal and external sources. For example, you may wish to relate the pay received by
employees with the same job duties or job titles to identify employees who are paid more or less than they
should be for the skills they have and the duties they must complete.
Succession Planning Systems
An important role of human resource departments is to make certain that replacements for key
organizational personnel are available when the positions key personnel occupy become vacant because
of death, injury, retirement, or other reasons. Planning for the succession of these key people means
identifying replacement employee.
21.10 Strategic Human Resource Information Systems

Human resource planning ensures that the organization has the right kinds and the right numbers
of people at the right places at the right time to achieve its objectives Several types of human resource
planning are strategic in nature, including workforce planning and labor negotiations.
Workforce Planning Systems
Organizations involved in long-term strategic planning, such as those planning to expand into
new market areas, construct factories or offices in new locations, or add new products, will need
information about the quantity and quality of the available workforce to achieve their goals. Information
systems that support workforce planning serve this purpose. This type of planning involves identifying
the human resources needed to meet the organizational objectives specified in the strategic plan and that
means forecasting the supply and demand of the required workforce. These forecasts are estimates of the
characteristics, quantity, and pricing of the labor force needed to achieve the long-term plans of the

organization.. Forecasting human resource needs requires information to answer a number of planning
questions, including the following:
1. What should be the labor force of the organisation look like to meet the strategic plan? What
skills, experiences, knowledge, and other qualities should be organisation’s human resource
process? In other words, what job descriptions and specializations does the strategic plan require?
2. What quantities of human resources with the qualities already identified are needed to carry out
the strategic plan? In other words, how many positions for each job title does the strategic plan
need?
3. What are the current human resources of the organization and how well do they satisfy the
organization's strategic needs for human resources?
4. 4. What other human resources are available to achieve the strategic plan?

Information Systems Supporting Labor Negotiations
Negotiating with craft, maintenance, office, and factory unions requires information gathered
from many of the human resource information systems already discussed. In addition, negotiators need

information from the financial accounting system and from external sources, including competitor wage
agreements and appropriate economic data for the industry, employee group, and geographical region.
Much of the external information required by a negotiating team can be obtained from the on-line data-
bases discussed in Chapter 7. The human resource team completing the negotiating needs to be able to
obtain numerous ad hoc reports that analyze the organization's and union's positions within the framework
of both the industry and the current economic situation. The negotiating team must receive these ad hoc
reports on a very timely basis because additional questions and tactics will occur to the team while they
are negotiating.
21.11 Summary
Tactical information systems support managers in the allocation of resources to meet top
managements goals. Strategic planning information systems, support the setting of organization goals.
There are many applications of information becomes to tactical and strategic planning decisions in
business and organizations. This chapter briefly defines applications to panning decisions in finance,
marketing, production & human resources.
Financial information systems include tactical terms such as budgeting, cash management, capital
budgeting, and investment management, and strategic systems, such as financial conditions analysis and
long term forecasting. .A wealth of internal sources of information exists for these information systems,
and many general purpose and software tools are also available.
Marketing information systems support managers in the management and control of the sales
force, sales campaigns, advertising promotion campaigns, and the distribution and delivery of goods and
services, as well as in tracking competitors. Strategic marketing information systems include sales
forecasting, market research, and product planning and development.
Many tools are available to assist marketing managers in tactical and strategic decision making,
including data warehouses, geographic information systems, on-line and Internet databases, and CD-ROM
Databases
Tactical and strategic production information systems support decision making for the allocation
and planning of manufacturing and production resources. Many information systems have been developed
to assist in controlling inventories: estimating, assigning, and monitoring production capacity; designing
products and services; scheduling production facilities; allocating human resources; controlling
production projects; assessing production technologies; planning for the development of new plants;
deciding on the level of vertical integration; and designing plant facilities. These information systems use
data from the organization's financial accounting and human resource databases. In addition, many
external sources of information, such as on-line government, scientific, and industry databases and Internet
sites, provide support for strategic planning.
The continued use and refinement of computer support for manufacturing am' production opera-
tions and decisions is leading organizations to an integrated approach to the management of manufac-
turing and production systems.
Human resource departments are responsible for many facets of human resource management,
including tactical decision making in the areas of recruiting, training, compensation, benefit management,
and job analysis and design. HR managers also provide top management with information for strategic
planning, including providing workforce plans and support for labor negotiations.

UNIT IV
Lesson 22 – Tactical and Strategic Level Information Systems
Learning Objectives
• To have a better understanding about the various Information Systems at the managerial and
strategic level of any organisation
• To know about the various functional information systems at managerial level.
• To identify the components and the benefits of operational level systems.
• To know about the support extended by these systems in Management Decisions
21.1 Introduction
As you move up the organizational ladder from supervisory positions to middle- and upper-
management positions, you will make decisions that have an increasingly greater impact on the
organization. The decisions you may face along the way are diverse and could include decisions similar to
these:
1. Should you purchase a new piece of equipment or lease the equipment for a three-year
period?
2. Is the idle cash of your firm being invested wisely?
3. Should you invest money in new computer equipment or in additional merchandise for
resale?
4. What criteria will you use to create territories for your salespeople and how large of a
territory should each salesperson cover?
5. What products should be emphasized through advertising or promotion to reach the firm's
sales goals?
6. What are the best potential sites for a new retail store location?
7. How many and what types of workers will be needed to staff a new plant in another state?
This lesson examines the types of tactical and strategic decisions that you may make as you move up the
ranks of middle and upper management. Specifically, we examine the application of information
technology to some of the tactical and strategic information systems frequently used by middle and upper
management in four organizational functions: accounting/finance, marketing, production, and human
resource management.
21.2 The Nature of Tactical and Strategic Information Systems
Tactical information systems support management decision making by providing managers with
regular summary reports, regular exception reports, ad hoc reports, and other information that helps them
(1) control their areas of responsibility and (2) allocate their resources to pursue organization goals. While
the focus of operational information systems is on the completion of tasks, the focus of tactical
information systems is on resource allocation; that is, how do you allocate the resources available to you
to reach organizational goals.

In contrast, strategic-level information systems are goal oriented. That is, these systems are
designed to support organizational goal and direction setting.

It is difficult at times to categorize some information systems as dearly tactical or dearly strategic.
For example, some marketing information systems, such as marketing research systems and competitor
tracking information systems, dearly could support both tactical and strategic planning decision-making.
Sometimes the decision to categorize a decision as tactical or strategic comes down to the length of time
the decision is likely to impact an organization. That is, decisions that will impact an organization for a
year or less are often viewed as tactical, while decisions that will impact an organization for more than a
year are often viewed as strategic.
The computerization of financial accounting systems changed the way managers viewed
accounting information. A large database of information became available in computerized form, and it
could be viewed or manipulated much more easily than data in traditional hard copy form. So managers
began to view this information as a resource for tactical planning. Suddenly managers could obtain
important summaries and comparisons of financial accounting data easily and swiftly. In the past this
information would have taken a great deal of time to extract from a manual financial accounting system.
The result was that managers began to view the financial accounting system as more than merely a
transaction-processing system, a producer of checks, invoices, and statements. It became a repository of
important data that assists management in tactical decision-making and long-range strategic planning.
21.3 Tactical Accounting and Financial Information Systems

Budgeting Systems permits managers to track actual revenues and expenses and compare these amounts
to expected revenues and expenses. It also allows managers to compare current budget amounts to those
of prior fiscal periods, other divisions, other departments-even to industry-wide data. Comparisons of
budget data against such standards allow managers to assess how they use their resources to achieve their
goals. For example, a manager may view the budget to find the amount of money actually spent in the
purchasing department on supervisory versus clerical staff. The manager may then compare those
amounts to the amounts spent by other purchasing departments in the organization or in the industry.
For example, the general ledger system of a financial accounting system may provide these
reports:
1. Current budget allocations, expenditures, and variances by budget line item.

2. Current budget allocations compared to the previous year's allocations.
3. Current revenues and expenditures compared to the previous year's revenues and expenditures.
4. Current revenues and expenditures compared to the average of the other units or divisions of the
organization.
5. Projected expenditures and variances for each budget line item for the entire year based on the
expenditures incurred to date.
Regularly produced tactical-level reports, such as budget variance reports, often generate
managerial questions and concerns. These in turn may lead managers to query the financial accounting
database for answers or solutions. Suppose, for example, that you are an accounting manager and
supervise several departments, including the billing department. Suppose further that the regular budget
report shows that the wages line of the billing department report is much higher than in prior years. To
find out why, you might query the financial accounting database for answers. If the database stores the
number of statements produced each month, the number of employees in the billing department, and the
costs associated with the billing department, you might obtain various measures of the productivity of that
department, such as the average number of statements produced per billing department employee and the
average cost per statement. If you found poor productivity results, you might then examine the
productivity of each billing supervisor compared to the average for the organization or the productivity of
each billing clerk compared to the average for the department. This information might lead you to
decisions about changing supervisory personnel, providing training for specific billing clerks, acquiring
new equipment to produce customer statements, or other possible remedies. Notice that the system does
not make the decisions for you; it provides information to help you identify and remedy problems. It is a
decision-support system, not a decision system.
Cash Management Systems
A cash flow report shows the estimated amount of cash that will be received and spent each
month. The report shows which months will have excess funds that might be put to use and which months
will have insufficient funds, which may require the organization to borrow cash to meet its working
capital or fixed asset acquisition needs.
Cash management systems are more difficult 'to sustain for smaller organizations that may not
be able to afford the resources necessary to track cash balances on a day-to-day basis and invest the
excess to maximize organization income. Recognizing that difficulty, Merrill Lynch, a brokerage house,
created a product in the 1970s that offered business customers an account combining the attributes of a
money market account, a brokerage account, a margin credit account, and a checking account. The
product, called the cash management account (CMA) provided business customers with automatic

deposits of cash and dividends from other accounts into a money market account. This option gave
organization high interest rates on idle cash resulting from sales of stock, receipts of dividends, or
deposits made for the purchase of stock. Organizations could also use a debit card and checks to withdraw
money from the money market account. The result was that a small organization could use the service to
maximize its income from idle cash sometimes available in its normal cash flow.
Capital Budgeting Systems
A capital budget contains information about the planned acquisition or disposal of major plant assets
during the current year. The manager may compare the various capital spending plans using three
commonly used evaluation tools: net present value, internal rate of return, and payback period. Before the
plant asset is acquired, the manager should compare and evaluate various plans for its acquisition using
some financial software tool, such as an electronic spreadsheet.
For example, suppose a manager is considering acquiring a large electronic printer and estimates
that her firm will keep the machine for five years. The printer may be purchased or leased. Each method
requires the manager to spend different amounts of money over different periods of time. The manager
can improve the decision to buy or lease by evaluating the present value of the funds each method
requires.
Investment Management Systems
Investment management-overseeing the organization's investments in stocks, bonds, and other

securities-is an important part of cash management. Managing investments is also an important part of
managing the organization's pension plan. Whatever their source of investment funds, most organizations
invest money in securities of one kind or another. Careful management of these investments is necessary
to ensure the achievement of organization goals.
21.4 Strategic Accounting and Financial Information Systems
Strategic accounting and financial information systems typically include several type of information
flows:
1. Internally generated financial condition analysis data, describing the status of the organization.
2. Externally generated economic, demographic, and social data describing the present and future
environments for the organization.
3. Forecasts of the future of that organization in those environments.
Two major outcomes of financial strategic planning are the setting of financial goals and directions of
the organization. The former may include setting goals for investments and return on investments. The
latter may involve deciding on new investment opportunities or on the mix of capital sources used to fund
the organization.
A major source of computerized information about the current and future Status of the organization is
the organization's own financial accounting database. A major source of computerized information on the
present and future environments in which the organization must operate are on-line databases that contain
economic, special, demographic, technological, and political information. Projecting likely scenario for
the organization using these two categories of data is the art of forecasting. Its’ major purpose of strategic

decision making is to use long-range forecasts to reduce the risk involved in major organizational
decisions.
Financial Condition Analysis Systems
Computerized accounting systems provide the user with many reports to which conditions and analysis
tools may be applied. For example, the manager may use a variety, analysis tools, on the data reported on
the income statement and balance sheet. Many computerized accounting systems supp reports that
automatically calculate and present the results of these tools and ratio Along with the data and reports,
these tools and ratios make up the organization financial condition analysis system. This system
provides management with variety of measures of the soundness of the organization and makes it possible
to explore ways of improving the organizations financial condition.
Commonly used financial ratios

RATIO NAME RATIO FORMULA
Current ratio Current assets ÷ current liabilities
Working Capital Current assets - current liabilities
Inventory turnover Cost of goods sold ÷ average inventory
Debt-to-equity ratio Stockholder equity ÷ total liabilities
Rate earned on stockholder’s equity Net income ÷ average stockholder’s equity
Earnings per share Net income ÷ number of shares
Long-Range Forecasting Systems
Strategic planners demand forecasts on a variety of factors that will affect organization performance in
the future. Some forecasts may involve the use of internally generated data. For example, past sales data
may be used to project future sales. Other forecasts may use only external data or both internal and
external data. For example, forecasting economic indicators helps planners understand the likely
economic environment in which the organization must operate in the future. Forecasting the financial
health of the organization through long-range budget estimates-including a variety of possible wage
negotiation settlements, actions by competitors, interest rate fluctuations, fuel cost changes, and different
inflation rates-provides planners with opportunities to consider actions that will help the organization
survive bad times or take advantage of a future environment.
Information used in forecasting the future environment includes descriptions of the past activities
of an organization, data on the present economy and forecasts of the future economy, information on the
present demographic structure of the region or country and forecasts of the future demographic structure,
and descriptions of the current social structure and social mores and predictions of the future structure of
society and societal mores.
21.5 Tactical Marketing Information Systems
As you learned, the marketing function is the satisfaction of the needs and wants of customers-
current and potential. Marketing managers engage in many planning activities in the pursuit of the
marketing function. These planning activities result in a combination of products, services, advertising,
promotion, price, and product delivery methods ultimately offered to the organization's customers, which
is referred to as the marketing mix.

Tactical marketing information systems differ from operational marketing information systems
because in addition to producing information on a regular basis, they also generate ad hoc reports, create
unexpected as well as expected output, produce comparative as well as descriptive information, provide
summary information as opposed to detailed data, include both internal and external data sources, and
process subjective as well as objective data.
A great deal of the data that tactical marketing information systems utilize is collected by
operational financial information systems. Tactical marketing information systems often combine
operational-level financial data with other data to support tactical decision making by marketing
managers. Tactical decisions are often made by managers when they prepare and implement marketing
plans through which they hope to reach top management's sales and profit
A major objective of marketing managers is to reach the sales goals set by top management. To
accomplish this objective, marketing managers must make many tactical decisions, such as how sales
territories should be shaped, how the sales force should be allocated within those territories, and what
emphasis should be placed in the products offered and customers served. Marketing managers must
decide ho to reward salespeople to encourage increased sales efforts, which market segment should be
emphasized to best reach sales goals, and which products and service will best appeal to each segment.
They also must monitor the progress of the sales effort to determine if their decisions were correct or if
they need to change the tactical plans.

Sales Management Systems
Sales management systems enable marketing managers to assess the productivity of the sales
force; the fertileness of sales territories; and the success of products by salesperson, territory, and
customer type. Sales management systems keep track of salesperson call activities, sales orders, and
customer activity. The systems allow the manager to identify weak territories or weak products in a
territory; to compare salesperson performance by product and customer type; to compare salesperson
performance against salesperson goals; to analyze salesperson calls within territories or by customer type;
to identify trends in customer purchases; to identify potential shortages or excess stock in inventory; and
to perform other planning, controlling, and organizing tasks with ease and speed.
Advertising and Promotion Systems
Marketing managers also need to develop advertising and promotional tactics to implement
strategic sales goals set by top management. Managers must decide which advertising media and
promotional devices to use to reach the selected market segments, when to use these media and devices,
and what overall mix of promotional activities to deploy to achieve sales goals. Advertising and
promotion systems assist managers in these tasks.
Pricing Systems
Pricing systems provide information to managers that helps them set prices for their products and
services. These information systems are important because the price of a product or service affects the
sales volume and profitability of the organization. The marketing manager usually selects a price that will
recover production costs and provide a profit, but the price chosen in constrained by the prices of com-
petitors for similar products or services and for alternative products or services. To make pricing
decisions, the marketing manager should know the expected demand for the product or similar products,
the desired profit margin for the organization, the costs of producing the product or providing the service,
and the prices of competing as well as substitute products. Substitute products refer to products that might
be used instead of the original product, particularly when that product is viewed as too expensive by the
customer. For example, a person might drive to a destination if the price of an airline ticket is viewed as
too expensive.
Distribution Channel Systems
To support the marketing manager, the marketing information system should provide distribution
channel decision-support systems. These systems should provide information on the costs of using the
various distribution channels, the time lags caused by the various channels, the reliability of the various

channels in delivering the products and services, and the market segment situation provided by the
channels. The systems should also track the demand and inventory at all levels of the distribution
channels so that the manager may anticipate excess inventories and shortfalls.
Competitive Tracking Systems
To ensure that your organisation’s marketing mix will continue to satisfy customers, you must
keep abreast of major competitors and their activities. In the end, market share is likely to be greatest for
the organisation that provides the marketing mix most closely matching a given market segment’s needs
and wants. Competitive Intelligence, or knowledge of the competitor prices, products, sales, advertising,
and promotions, must be gathered if the organisation is to avoid falling behind the competition in the eyes
of the customers. Gathering competitive intelligence is carried out through competitive tracking systems.
It should be noted that data about competitors can be used both tactically and strategically by managers.
21. 6 Strategic Marketing Information Systems
To develop an overall marketing plan, an organization may engage in a variety of tactical and
strategic planning activities (see Figure 11-8). The strategic activities may include segmenting the market
into target groups of potential customers based on common characteristics, needs, or wants; selecting
those market segments the organization wishes to reach; planning products and services to meet those.
customers' needs; and forecasting sales for the market segments and products. The tactical activities have
already been described and include planning the marketing mix-the best combination of product, price,
advertising, promotion, financing, and distribution channels to reach the chosen target groups. The
strategic activities revolving around sales forecasting and product planning decision making will now be
discussed.
Sales Forecasting Systems
Strategic sales forecasting systems usually include several varieties of forecasts: forecasts of sales
for the industry as a whole, forecasts of sales for the entire organization, forecasts of sales for each
product or service, forecasts of sales for a new product or service, and forecasts for market segments. The
results of these .sales forecasts are often further categorized by sales territory and sales division.
Regardless of type, sales forecasts are usually based on more than historical data; they are not merely
projections of past trends. Sales forecasts are also based on assumptions about the activities of the
competition, governmental action, shifting customer demand, economic trends, demographic trends, and a
variety of other pertinent factors, including even the weather.
Marketing Research Systems
In large organizations, research departments conduct and manage marketing research. In smaller
companies, marketing research may be completed by outside consultants or by personnel who must wear
several hats. Regardless of how the function is completed, the results of marketing research provide
important input to both tactical and strategic decision making.
These following activities are typical of a marketing research department.

1. Conducting trend analyses of industry sales of products and services identical or
similar to those offered by the organization to identify products or services that are on the
ascent or descent.
2. Analyzing population and target group characteristics, especially for trends or changes in data
that could affect the organization.

3. Analyzing and identifying consumer preferences, including testing products and services.
4. Determining and analyzing customer satisfaction with the organization's existing products
and services.
5. Estimating market share for all of each product and service offered.
Product planning and development systems
The major objective of product planning and development systems is to make information
about consumer preferences obtained from the marketing research system and from customer inquiries
available for the development of new products. The primary output of planning and development
activities is a set of product specifications. In a manufacturing organization, these specifications would be
given to the engineering department, which would try to design a product to. meet them. Similar activities
occur in service organizations. For example, a survey Of bank .customers may indicate that customers
would like a checking account that also acts like a savings account-an account in which they could place
all their money, maximize the amount of cash earning interest, avoid multiple statements, and avoid the
need to shift funds between savings and checking accounts. Bank personnel charged with product
development may then identify specifications for such a product that meet current banking laws and
regulations. These specifications may require the new account to carry the same rate of interest as a
passbook savings account, earn interest on the average balance on deposit during a month, not limit the
number of deposits or withdrawals during a month, maintain a minimum balance of $500, and pay
interest monthly. The specifications can be tested and refined through additional consumer surveys and
focus groups or through testing the product in a subset of the market, such as one branch of the bank.
21.7 Tactical Production Information Systems
Production systems encompass all the activities necessary to ensure the manufacture of products
or services. To perform its functions, the production system must locate production sites, plan the layout
of those sites, and produce a production plan. '{he production system has to acquire the raw materials,
parts, and subassemblies needed to produce the products or services described in the plan and to identify
how many workers of each type are required. The system must then allocate or acquire workers with the
appropriate skills, make certain that sufficient work space and production equipment are available, and
schedule an integrated use of these resources to produce the correct quantity of goods at \he correct time
to meet the marketing system's forecasted needs. While production is under way, the system also must
monitor the use and cost of those resources.
Materials Requirements Planning Systems
Inventory management can be taken a step further so that the system automatic produces
purchases orders for stock that needs to be reordered. Materials requirement planning (MRP) software is
basically a set of programs that use data from master production schedule, inventory files, and bill-of-
materials systems-or list raw materials and components needed to create each product-to help manage
production and inventory.
MRP systems perform a great deal of calculation and record keeping. When (quantities of raw
materials and parts are large, the calculations and record keeping become too time-consuming to complete
manually, except at high costs. The computer, however, has made such calculations and purchase-order
preparation possible for all of organizations, and in recent years, software to implement materials requires
planning has become abundant.
Just-in-Time Systems

The just-In-time (JIT) system is not tactical information system, but a tactical approach to
production. The just-in-time approach was created by the Toyota Motor Company of Japan and has
generated many advantages to organizations, especially those that do repetitive production. The purpose
of the approach is to eliminate waste in the use of equipment, parts, space, workers' time, and materials,
including the resources devoted to inventories. The basic philosophy of JIT is that operations should
occur just when they are required to maintain the production schedule. To assure a smooth flow of
operations in that environment, sources of problems must be eradicated. That means that quality must be
emphasized because quality problems interfere with the even flow of work. For inventory management,
JIT translates into having just as much inventory on hand as is absolutely needed, which is achieved by
developing efficient and effective production controls.
Capacity Planning Systems
In addition to ensuring that enough raw materials will be on hand for planned production, the'
production manager must also see to it that enough production capacity will be available to meet
production' goals. The purpose of capacity planning is to make certain that sufficient personnel, space,
machines, and other production facilities are available at the right time to meet the organization's planned
production. Managers also utilize capacity planning to minimize excess production capacity.
Capacity planning decisions are tactical production decisions and include allocating personnel
and production facilities. Selecting sites for constructing plant facilities, acquiring plant facilities, and
planning those facilities to meet long-term production goals are usually categorized as strategic planning
production decisions.
Production Scheduling Systems
The purpose of the production schedule is to allocate the use of specific production facilities for
the production of finished goods to meet the master production schedule. To manage the scheduling
process, a number of scheduling tools have been developed. Two of these tools are Gantt and PERT
(Program Evaluation and Reporting Technique) charts.
These tools allow managers to control projects and project completion times and also to
determine the impact problems will have on project completion dates. For example, top management may
ask a manager to complete a project sooner than originally planned. The manager may then consider ways
to shorten the duration of the project by completing two tasks at once. However, to complete two tasks
concurrently may raise production costs substantially, because two production teams and two production
facilities may be needed. To solve the problem, the manager may create what-if scenarios with the project
conditions using the PERT chart tool. However, Product Design and development Systems completing
multiple PERT charts manually requires extensive calculations and may prove frustrating to the manager.
Computer-generated PERT charts let the manager simulate many scenarios with speed and ease. The use
of 'project management software for this purpose is discussed later in this chapter.
Product Design and Development Systems
Many tactical decisions must be made to design and develop a product, especially a new product.
The design engineering team usually depends on product specification information derived from customer
surveys, target population analysis, or other marketing research systems.
The primary objective of the design .engineering team is to develop a product that meets perceived needs
of customer. However, the team's tactical task is to achieve that objective with the least demand on

company resources. Designing products to contain or reduce costs often results in ingenious uses of raw
materials, labor, and machinery. Through careful design, an engineering team can often design a product
that can be produced at lower costs than competitors can produce it. Careful design may also lead to a
simpler product, which leads in turn to fewer maintenance problems, better customer acceptance, fewer
product returns, and increased product repeat sales. Through the use of product design and development
systems, the . engineering team may provide the company with important competitive advantages.
Manufacturing Resource Planning Systems
More recently, software that provides for manufacturing resource planning (MRP-II) has become
available. MRP-II software extends the production information system to finance, marketing, human
resource management, and other organizational functions. A fully developed MRP-II system includes
modules that provide material requirements planning, shop-floor control, inventory management, and
capacity planning. The system also accesses cost accounting data through integration with the financial
accounting system. MRP-II systems usually accept data from a wide range of shop-floor data collection
equipment, including voice recognition equipment, factory robots, production-line sensors, process
control systems, bar code readers, and CAD workstations.
Computer-Integrated Manufacturing Systems -
Many production professionals envision a day when factory and product planning control, design,
and operation will be totally integrated and almost totally computerized. Some software and hardware
firms that provide MSP, MRP, MRP-II, CAD, CAM, CAI CAT, CAPp, CAl, robotics, and related
information systems are joining forces through mergers, acquisitions, and joint projects to integrate
current production hardware an software products into systems that provide computer-integrated
manufacturing (CIM), A growing number of manufacturers are utilizing CIM -or at least a great mar
components of CIM-to run their factories. Implementing CIM can lead to considerable cost savings,
improvement in quality, and more flexible responses to customer.
21.8 Strategic Production Information Systems

Strategic production information systems provide support for top-management-Ie1 production decisions
such as:
• Selecting a plant site.

• Constructing a plant addition.
• Building a new plant.

• Designing and laying out a production facility.
• Choosing the technologies that will be used in the production processes.
• Choosing responsibility for production processes-deciding basic policies on vertical
integration and outsourcing.
Decisions of this magnitude require the commitment of a large amount of capital and other resources
over a long period of time and thus are strategic in nature. Clearly, such decisions must not be made
lightly.
Site Planning and Selection Systems
Site planning systems usually rely on a variety of internal and external sources. Some of the
external information needed is relatively objective and quantitative, such as the availability and cost of
trained or experienced labor and the degree to which it is unionized, the availability and cost of

transportation for raw materials and finished goods, the availability of suitable sites, the cost of land, the
proximity of raw materials suppliers and finished goods customers, the availability and costs of power,
and the rate of property and income taxation.
Technology Planning and Assessment Systems
Having access to information on new; production technologies allows top management to make
better and more informed decisions about which production technologies to use for a product or service.
Technology assessment systems, which identify new technologies and assess them for their strategic
advantage, can help top management in many areas, not merely production. Like site planning,
technology information systems may include CD-ROM databases, traditional library resources, Internet
sites, and on-line databases maintained by government agencies, industry groups, private research groups,
and consulting organizations. They may also include technology assessment groups within the production
or engineering arms of the organization.
Process Positioning Systems
An important part of any organization's strategic production plan is the span of production
processes it decides to perform for any given product or product line. Decisions of this nature are called
process positioning, or vertical integration. An organization might purchase raw materials, fabricate
parts, assemble; parts into subassemblies, and then assemble and test the complete product. It may, on the
other hand, decide to purchase already constructed subassemblies and parts from others and limit its
internal span of production processes to assembling and testing the plant Design Systems completed
product. Outsourcing subassemblies, for example, to production facilities in third world countries, may
allow the organization to gain a competitive advantage by being a low-cost leader for its products.
Plant Design Systems
Designing and laying out a manufacturing plant requires large amounts of diverse information
about the proposed plant, including engineering data on the proposed site, proposed production
technologies, the number and duties of plant personnel, the expected schedule for the use of the facility,
the area transportation system, choices of water and power systems and their costs, the cost and
availability of construction materials, the plans for shop-floor information systems, and the need for
physical security. Much of this information is available to the plant design system from the site planning,
technology assessment, and process positioning decision processes.
21.9 Tactical Human Resource Information Systems
To assist managers in managing human resources, a number of information systems, called

human resource information systems (HRIS), have been developed (see Figure 11-1). Human resource
information systems contain personal information about the employees of an organization, and securing
this information against unwanted or unwarranted access, use, or distribution is terribly important to the
individuals involved. Unwarranted access, use, or distribution is also likely to be illegal under current
legislation and can subject the organization to serious legal liability. Security issues surrounding
databases, such as the human resource information database and the computer systems that house these
databases, are discussed in greater detail in Chapter 17. Human resource information systems include a
number of tactical and strategic information systems. Tactical HRIS include job analysis and design,
recruitment, training and development, and employee compensation. Strategic HRIS include information
systems that support workforce planning and labor negotiation.

Jon Analysis and Design Systems
Job analysis and design includes describing the jobs needed in an organization and the qualities of
the workers needed to fill those jobs. These tasks involve the development of job descriptions for every
type of position in an organization. Each job description specifies the purposes, tasks, duties, and
responsibilities of each job and the conditions and performance standards under which those duties and
responsibilities must be carried out. Job analysis and design also includes the development of job specifi-
cations for each type of job. A job specification describes the skills, knowledge, experience, and other
personal characteristics required to perform the jobs that are listed in job descriptions. In short, job
descriptions describe the jobs, and job specifications describe the workers needed to fill those jobs.
Recruiting Systems
A recruiting system should provide the organization with a bank of qualified applicants from
which it may fill vacant positions identified through the position control system and described by the job
analysis and design information system. The recruiting function should also ensure that the organization
is in compliance with various federal, state, and local statutes and contract regulations for affirmative
action and equal employment opportunity.
Compensation and Benefits Systems
To help human resource managers control their compensation and benefit plans, organizations
must keep and maintain information describing the various pay plans and fringe benefits as well as the
choices of each employee. The compensation and benefits system may support a variety of tactical
human resource decisions, especially when compensation and benefits information is related to
information from internal and external sources. For example, you may wish to relate the pay received by
employees with the same job duties or job titles to identify employees who are paid more or less than they
should be for the skills they have and the duties they must complete.
Succession Planning Systems
An important role of human resource departments is to make certain that replacements for key
organizational personnel are available when the positions key personnel occupy become vacant because
of death, injury, retirement, or other reasons. Planning for the succession of these key people means
identifying replacement employee.
21.10 Strategic Human Resource Information Systems

Human resource planning ensures that the organization has the right kinds and the right numbers
of people at the right places at the right time to achieve its objectives Several types of human resource
planning are strategic in nature, including workforce planning and labor negotiations.
Workforce Planning Systems
Organizations involved in long-term strategic planning, such as those planning to expand into
new market areas, construct factories or offices in new locations, or add new products, will need
information about the quantity and quality of the available workforce to achieve their goals. Information
systems that support workforce planning serve this purpose. This type of planning involves identifying
the human resources needed to meet the organizational objectives specified in the strategic plan and that
means forecasting the supply and demand of the required workforce. These forecasts are estimates of the
characteristics, quantity, and pricing of the labor force needed to achieve the long-term plans of the

organization.. Forecasting human resource needs requires information to answer a number of planning
questions, including the following:
1. What should be the labor force of the organisation look like to meet the strategic plan? What
skills, experiences, knowledge, and other qualities should be organisation’s human resource
process? In other words, what job descriptions and specializations does the strategic plan require?
2. What quantities of human resources with the qualities already identified are needed to carry out
the strategic plan? In other words, how many positions for each job title does the strategic plan
need?
3. What are the current human resources of the organization and how well do they satisfy the
organization's strategic needs for human resources?
4. 4. What other human resources are available to achieve the strategic plan?

Information Systems Supporting Labor Negotiations
Negotiating with craft, maintenance, office, and factory unions requires information gathered
from many of the human resource information systems already discussed. In addition, negotiators need

information from the financial accounting system and from external sources, including competitor wage
agreements and appropriate economic data for the industry, employee group, and geographical region.
Much of the external information required by a negotiating team can be obtained from the on-line data-
bases discussed in Chapter 7. The human resource team completing the negotiating needs to be able to
obtain numerous ad hoc reports that analyze the organization's and union's positions within the framework
of both the industry and the current economic situation. The negotiating team must receive these ad hoc
reports on a very timely basis because additional questions and tactics will occur to the team while they
are negotiating.
21.11 Summary
Tactical information systems support managers in the allocation of resources to meet top
managements goals. Strategic planning information systems, support the setting of organization goals.
There are many applications of information becomes to tactical and strategic planning decisions in
business and organizations. This chapter briefly defines applications to panning decisions in finance,
marketing, production & human resources.
Financial information systems include tactical terms such as budgeting, cash management, capital
budgeting, and investment management, and strategic systems, such as financial conditions analysis and
long term forecasting. .A wealth of internal sources of information exists for these information systems,
and many general purpose and software tools are also available.
Marketing information systems support managers in the management and control of the sales
force, sales campaigns, advertising promotion campaigns, and the distribution and delivery of goods and
services, as well as in tracking competitors. Strategic marketing information systems include sales
forecasting, market research, and product planning and development.
Many tools are available to assist marketing managers in tactical and strategic decision making,
including data warehouses, geographic information systems, on-line and Internet databases, and CD-ROM
Databases
Tactical and strategic production information systems support decision making for the allocation
and planning of manufacturing and production resources. Many information systems have been developed
to assist in controlling inventories: estimating, assigning, and monitoring production capacity; designing
products and services; scheduling production facilities; allocating human resources; controlling
production projects; assessing production technologies; planning for the development of new plants;
deciding on the level of vertical integration; and designing plant facilities. These information systems use
data from the organization's financial accounting and human resource databases. In addition, many
external sources of information, such as on-line government, scientific, and industry databases and Internet
sites, provide support for strategic planning.
The continued use and refinement of computer support for manufacturing am' production opera-
tions and decisions is leading organizations to an integrated approach to the management of manufac-
turing and production systems.
Human resource departments are responsible for many facets of human resource management,
including tactical decision making in the areas of recruiting, training, compensation, benefit management,
and job analysis and design. HR managers also provide top management with information for strategic
planning, including providing workforce plans and support for labor negotiations.

UNIT IV
Lesson 23 - Managing Knowledge in the Organisation
Learning Objectives
• To explain organizational knowledge management

• To study about the useful applications for distributing, creating, sharing knowledge
• To demonstrate how the various techniques improve knowledge base
22.1 Introduction
In many cases, decisions are too subjective or too large. Yet, decision makers can still use
some help. Many organisations make the same difficult decisions every month or every year.
Difficult decisions can require the participation of dozens of employees and analysis of gigabytes
of data. It would be nice if the organisation could keep the knowledge gained from every decision
and apply it to similar problems in the future. In the past, maintaining organisational knowledge
was a key management factor in retaining and promoting key employees. But in medium and
large organisations, turnover, distance, and the challenge of finding the experts can make it
difficult to maintain and share the knowledge. So, some companies have attempted to create
Knowledge Management (KM) Systems.
A KM system is designed to store any type of data needed to convey the context of the
decision and the discussion involved in making the decision. While the system might contain
rules, it is primarily a giant database of easily accessible data for experts. As we've mentioned in
other chapters, information is becoming an important corporate resource that must be captured,
protected, preserved, and grown. How you do that is the focus of this chapter.
22.2 Knowledge Management in the Organization
Creating and using knowledge is not limited to information-based companies: it is

necessary for all organizations, regardless of industry sector. It's not enough to make good
products; companies must make products that are better, less expensive to produce, and more
desirable than those of competitors. Using corporate and individual knowledge wisely will help
companies do that.
In the last few years, companies have downsized and flattened their organizations. Many
of the employees who were laid off had been with the company for years. When they walked out
the door, they took experience, education, contacts, and information with them. The companies
are finding out how important that human resource is to their success.
And as companies continue to expand on a global basis and increase their use of
technology to connect workers, they have to devise methods of disseminating information quickly
to as many people as possible. If an employee in Chicago has experience with a certain
production method, it would be silly not to share that information with employees in Singapore so
that they don't "reinvent the wheel."
So as knowledge becomes a central productive and strategic asset, the success of the
organization increasingly depends on its ability to gather, produce, maintain, and disseminate

knowledge. To understand the concept of knowledge management, think of knowledge as a

resource just like buildings, production equipment, product designs, and money. All these
resources need to be systematically and actively managed.
Information Systems and Knowledge Management
There are two main components to a Knowledge Management system: Office

Automation Systems (OAS) and Knowledge Work Systems (KWS).
We're all pretty familiar with OAS systems that secretaries, clerical workers, and some
professionals use. In fact, you've probably used some of the same applications contained in an
OAS. The most popular is the Microsoft Office suite, which includes word processing (Word),
personal information management systems (Outlook), spreadsheets (Excel), and database
software (Access). OAS systems help disseminate and coordinate the flow of information created
by someone other than themselves, BOTH internally and externally to the organization.
KWS, on the other hand, support the creation and integration of new knowledge that is
beneficial to the organization. One could argue that the most important element of a KWS is the
tacit knowledge that resides in the minds of the employees. Most other types of knowledge you
can learn from books. Tacit knowledge usually comes from experience.
The following figure shows the types of systems an organization would use to create knowledge,
capture and codify it, share the knowledge among people, and distribute it with various Office
Automation Systems.
How contemporary information systems support workers
Knowledge Work and Productivity

We could have a good discussion of productivity gains as a result of the increased use of
Information Systems of all kinds. The latest figures say that "productivity growth - which
languished at 1% during the 1970s and '80s - has taken a long-term leap to 2% or more as
companies use information technology to become more efficient."
To add another dimension, it has long been known that our government does not
adequately measure the dollar value associated with the export of information to foreign countries
and the products created in the Information Services sector. It's not as easy to count the products
from Information Services, such as software or financial advice, as it is to count the number of
cars loaded onto a ship bound for Europe.
One of the more interesting aspects of the discussion here is the statement "Évalue
created by computers may primarily flow to customers rather than to the company making the
investments." The customer is happier; but is the company more productive? And although the
company may not necessarily be able to count the productivity gains, it can realize gains from
satisfied customers who return for more products or more information or more services.
Simply throwing a computer on an employee's desk does not make him or her instantly
more productive or instantly smarter. You have to train people on the best use of the system. The
company as a whole also has to rethink processes, workflows, and goals. If you had a problem or
an inefficient process before, new hardware and software won't automatically fix it: think
business process redesign and paradigm shifts. Information and knowledge are key business
assets that must be nurtured, protected, grown, and managed for the benefit of the entire
organization.
22.3 Information and Knowledge Work Systems
Information work is the art of creating and processing information. We use the term "art"
because some companies do a very good job of creating, processing, and managing their
information; others do such a poor job that these tasks become a detriment to the success of the
organization. Which kind of company do you want to work for or own?
The two groups of employees primarily concerned with KWS are the data workers who
process and distribute information and the knowledge workers who create knowledge and
information. There are several ways to distinguish these two groups. You can also distinguish the
two by the type of work they perform and how they create and use information. Here are some
questions to help you:
• Do they create original ideas, or do they process, record, and store someone else's?
• Do they make their own original decisions regarding the information?
• Do they establish procedures to create and process the information, or do they follow
someone else's procedures?
Distributing Knowledge: Office and Document Management Systems

The office, as we know it in the traditional sense, is the setting for the generation and
processing of information. As the above figure shows, it's where different roles mesh into a
smooth "machine" of producing information, knowledge, and ideas instead of a product that you
can touch, feel, or smell.

The table describes typical Office Automation Systems and the activities they support, all
of which are vital to the success of the organization. While some OAS still rely on stacks and
stacks of paper, modern technology emphasizes digital sourcing, storage, and distribution. As
computers and associated technology become more embedded into the normal workflow of
offices, more is being done without paper. For instance, a clerical worker can create a document,
send it to co-workers or supervisors for their input via email, have it returned electronically,
correct it, and distribute it online.
But no matter how much we talk about a paperless society, we are actually generating
more paper than ever. One of the emerging technologies that is enhancing the productivity and
ease-of-use of Office Automation Systems and reducing paper problems is the document imaging
system, which converts documents and images into digital form so they can be stored and
accessed by computer.
Documents not in use are stored on-line on an optical disk system called a jukebox. The
index server maintains the information the system will use to locate, access, and retrieve a
document.
A wonderful example of document imaging systems is bank checks. Most banks don't
return canceled checks any more. They make a digital image of the check, store it electronically,
and then destroy the piece of paper. If you ever need a copy of one of your old checks, you have
to request it. While the initial use of paper isn't reduced, the cost of processing and mailing the
checks to the customer is gone altogether.

The advantages of using document imaging systems lie in the chance to redesign
workflows. If companies aren't willing to do this, then they are laying out a lot of money to buy
and install a system that they'll never fully use.
Creating Knowledge: Knowledge Work Systems
In this section we'll review many different Knowledge Work Systems (KWS) so that you
have a clear understanding of how they differ from OAS and other Information Systems. These
systems help create new products or improve old ones, and they're also used to integrate new data
into the flow of information that is so vital to an organization.
It's important that you understand the functions KWS perform. They:
• Keep the organization up-to-date in knowledge

• Serve as internal consultants
• Act as change agents
Requirements of Knowledge Work Systems
The first requirement of a KWS is that it provides knowledge workers with the necessary
tools:
• Graphics tools
• Analytical tools
• Communication tools
• Document management tools

The above figure also shows how the elements of a KWS work together. Note that this
kind of system requires links to external knowledge bases.
Most KWS require powerful workstations that can process the huge graphics files some
professionals need or perform the massive calculations other types of professionals require. We're
not talking clip art or simple adding or subtracting. We are talking huge amounts of data that must
be processed quickly and the necessary storage for large files. The workstations must also have
the necessary equipment and telecommunication connections that enable the knowledge workers
to connect to external sources of information via Extranets, Intranets, or the Internet. These
systems must have system and application software that is easy to use and manipulate, and
intuitive to learn.
Examples of Knowledge Work Systems
Pick up any business or technology magazine, or watch the news channels and you'll find
numerous examples of how companies are using Knowledge Work Systems to re-create their core
processes, create new products or services, or improve old ones. The text gives some excellent
examples:
Computer-aided design (CAD) applications are used by design engineers to build new
products or improve old ones. It used to take 3-4 years and millions of dollars to design a new
car. With improved CAD systems, automobile manufacturers have reduced the time to 18-24
months and cut the cost by millions of dollars. Boeing Company has seen the same startling
results in their design process for airplanes.
Virtual reality systems have sophisticated imagery that makes you feel like you're "right
there!" You may have seen this system on TV shows or in the movies. You're usually required to
wear special equipment that feeds your reactions back to the computer so that it can plan its
responses to your input. The U.S. Air Force uses virtual reality systems to help train pilots.
VRML (Virtual Reality Modeling Language) is a set of specifications for interactive 3-D
modeling on the Web. Many companies are putting their training systems right on the Internet so
that people can have access to the latest information and can use it when they need it. Some Web
sites use Java applets to help process the programs on the local workstation.
How would you like to make investment decisions based on information that is 90 days
old or older? Would you have very much faith in a system that told you only how the company
did financially last year, or would you also like to know how the company performed last
quarter? That's the idea behind investment workstations. They combine information about
companies that is internal and external, new and old, in order to advise clients on the best use of
their investment dollars. Massive amounts of data must be processed quickly in order to keep up
with changing market conditions and the changing nature of the industries themselves.
Sharing Knowledge: Group Collaboration Systems and Intranet Knowledge Environments
It's no surprise that the workplace is changing rapidly. In fact, you'd have a hard time
defining "workplace" in today's world. Group Collaboration Systems' role, along with Intranets, is
to support all the new and different ways we work.
Groupware

Lotus Notes is the best-known groupware application, with Microsoft Exchange

following closely in second place. The three Cs of groupware (communication, collaboration, and
coordination), allow people to work together from virtually anyplace on earth. Telecommuters,
and people assigned to geographically separated functions, can zip documents from one place to
another, or even better, work on the same document at the same time. According to an article in
Business Week magazine, Mar. 29, 1999, the most popular feature of groupware is email.
The newest version of Lotus Notes also allows users to hold online chat sessions. Users
know when their colleagues are online and can then discuss current projects with them in real
time. The use of groupware can reduce the costs of travel significantly and allow more
communication between people than ever before. This kind of software support gives global
companies tremendous advantages in merging their organizations and enhancing collaboration
between offices around the world.
The Lotus Web site, http://super.lotus.com, has an excellent online demonstration of

how you can use groupware and other features to enhance the three Cs of groupware, including a
new feature that allows mobile access to Intranets, Extranets, and Web sites.

This table gives you more ideas about how groupware can help companies organize and manage
knowledge.
Intranet Knowledge Environments
Joe, a mechanic in Mumbai, needs to fix a radiator in a car he hasn't seen in five years
(it's an old car). He can't remember exactly how the gasket fits on the top of the radiator or what
bolts he needs. He walks over to his computer, accesses the Intranet the automobile manufacturer
has established, clicks on the type of car, the type of repair, and downloads the latest information
about fixing the part. He can view a video file showing him how the gasket fits, listen to an audio
file that explains which bolts he needs along with acceptable substitutes, and read a warning
about the dangers he might face when he removes the radiator.

Instead of the hours it might have taken Joe before to look through a manual, fiddle with
the part, and try various methods of fixing the radiator, he can have the job done in less than half
a day. Joe saves time and money, the customer is happy to get his car back so quickly, and the
auto company saved hundreds of rupees training Joe.
Think about the other advantages of using Intranets to manage and disseminate this
knowledge. The auto company didn't have to process very much paper to get the latest training
manuals to Joe. Joe didn't have to sort through the new manuals, toss out the old, or ignore both
the old and the new while he tried to fix the part on his own. No one wasted time organizing the
most current information, and yet it was available whenever it was needed by whoever needed it.
Joe didn't need any special hardware or software or even any unique telecommunications
transmission media. All he needed was a regular cheap computer hooked to a regular cheap
telephone line. The company didn't have to install any special hardware or software other than
what it normally would have to access an ordinary Internet or Intranet site. If he had any special
questions, Joe could have sent an email to the technical support staff at the Repair Headquarters,
who would have answered his question via a return email.
The technical support staff at the Repair Headquarters would track Joe's question and if it
was unique, they would update their database with his question and answer so that it would be
available to other mechanics or other support staff. The question and answer, ultimately filed in
the database, would be available to the company's engineers for input in the next design review.
Amazing what we can do with today's technology! But what happens if Joe chooses not
to use the technology? What happens if the technical support staff decides not to share
information with the design engineers for fear they'll lose their jobs? What if the design staff
ignores the data available to them? We're right back to the triangle of hardware, software, and
persware. You've got to get the people to support the system and make it their friend so they will
use it to the benefit of the company.
You can distinguish between OAS and KWS systems by the way they manage
knowledge and information, and by the type of worker using them. OAS systems are comprised
of information processors, while KWS systems create and manage knowledge using Computer
Aided Design systems, virtual reality systems, and VRML. Knowledge is shared through the
groupware and Intranet components of a KWS.
22.4 Implementation of Knowledge Management in Organisation
I have become convinced that the question is no longer whether to implement knowledge
management (KM) in our organization, but how to implement it.
The real issue is how we use knowledge to better equip our employees to deliver quality services.
It is no longer a question of knowledge management (KM) versus information management (IM)
either, but rather a question of how best to implement both KM and IM as associated business
disciplines to improve the way we make decisions and provide service to our customers, as
individuals and as an organization. We are just embarking on a department-wide KM/IM
initiative with the objective to achieve a knowledge-empowered workforce. This experience has
afforded us several insights into the process of establishing KM, as well as the practical
outcomes.

If it isn't practical, it isn't tactical!
Recent departmental re-organization has provided us with a great opportunity to evaluate

our business processes and to start planning for some better corporate KM/IM principles and
practices. We have realized if we want to be deliverers of world-class services, we need to adopt
common KM/IM guidelines, procedures, and methodologies in order to maximize our return on
the huge intellectual assets we hold as an organization. We must define a set of management
principles that bind KM/IM to our business goals.
Without some stability in the organization, it will be impossible to get anyone's attention
for long enough to start looking at how KM and IM can help us work better and more effectively.
However, I also believe that as our new organization evolves it will become evident that KM/IM
holds the key to improved delivery of our services.
Step one: ask crucial questions
To change your organization's culture, you have to first get people onside by making it
relevant to them personally. If you want to help people to get comfortable with KM as a business
management tool there are three crucial questions you will need to address on behalf of your
employees:
• How is KM relevant to what I do?

• What specifically am I expected to do?
• What's in it for me?
Knowledge management and to a lesser extent information management are neither well
understood nor properly valued by the leaders of most organizations. I believe we haven't yet
made the connection between what people intuitively know and what organizations intuitively do.
We need to do a much better job of de-mystifying these two disciplines, and find a way to show
that they are neither elitist nor impractical.
Step two: adopt a set of guiding principles
In order to keep things simple, and to ensure that everyone can understand what you are
trying to do, you need guidelines. We are adopting a set of guiding principles to help us towards
implementing our KM/IM initiative:
• Corporate alignment - Align KM with business drivers and strategic goals in order to
ensure success
• Credible targets - Set an appropriate level of expectation around KM concepts so that
senior managers will buy in
• Clear language - Avoid jargon, and find an appropriate level of language that is clear and
consistent
• Constant communications - Keep talking about KM -- the average individual needs to
receive a message three times before they fully comprehend and digest it
• Consultation and collaboration - Provide tools and techniques for KM, and then let the
communities become sharing, yet self-sustaining, entities. Develop a model of central
alignment and de-centralized implementation.

Step three: find practical ways to move forward
You also need to find ways of moving these knowledge and information management
principles forward. While we have been going through these major changes, the department's
KM/IM office has been starting to work on practical ways to move the KM/IM yardsticks
forward, laying the foundations for future growth. In order to address the questions of fit and
relevance we can conduct a KM maturity survey, aimed at assessing the state of KM practices
and skills. The intention was to take a snapshot in time of how we operate, assess gaps and
impacts, and then start to address areas of concern. We can survey six knowledge dimensions:
Planning, Retention, Tools, Culture, Processes, and Sharing and Re-use. The overall rating will
show us just moving out of level one (chaotic) into level two (aware) for most dimensions.
Overall we can find that strategic areas where we have long-term competencies, such as business
analysis and planning, showed up better than tactical areas where KM has not had any real impact
yet, such as processes and practices.
Step four: develop the right tools and processes
In order to facilitate the tasks of our knowledge workers and communities, we have a tool
called the Knowledge Manager. It can be used by employees for KM analysis, planning and
decision-making, and connects departmental knowledge and information repositories through a
context-aware navigation tool. If we can start to imbed KM and IM attributes into our work
processes through the use of this tool, then we will be laying a solid foundation for future KM/IM
progress.
Step five: set realistic expectations
As we start to work in these areas, my most fundamental concern is that of setting a realistic
expectation level within the organization. It is vital that everyone understands that KM is not a
silver bullet, and that it is just another business management discipline that succeeds or fails
depending on how much attention we give it. The message is simple: KM is about making better
decisions together, nothing more.
At the same time we will start to address the issue of change management, the people factor.
While culture is a crucial factor, it is also evident that cultures are infinitely adaptable given the
right set of circumstances. I believe that it is the other "c-word," -- communications -- that we
should be more concerned with. Current KM survey data highlights lack of communications as
the single biggest reason that KM initiatives fail.
22.5 Summary
A winning strategy for any KM initiative needs to be one that addresses many different
organizational requirements: fiscal, cultural and operational, and yet has the virtue of simplicity.
A strategic plan needs to set realistic yet attainable goals, and should be able to resonate with any
audience at any level within the department. If people understand what you are trying to do, and
can see clear benefits to their participation, you stand a good chance of succeeding.
However, while KM is arguably an evolutionary rather than a revolutionary development,

there are several aspects of this current phenomenon which taken together represent a significant
change in the way organisations manage people, processes and information. KM involves taking
a more holistic view of information, not only combining internal and external information -

previously practised in some corporate libraries, relatively rarely in other sectors - but also co-
ordinating planning and control (monitoring) information, and consolidating informal ('soft') and
formal ('hard') information. KM also requires a strategic focus on valuable knowledge,
concentrating on knowledge that will contribute to the improvement of organisational
performance.

UNIT IV
Lesson 24 – Enterprise Information Systems I
Learning Objectives
1. To understand the use of Information Systems in various business processes

2. To study the role of IS in Cross-functional systems and Enterprise Information Systems
3. To learn about Marketing Information Systems and Production Information Systems
23.1 Introduction
In the previous two lessons we have discussed the information systems at various levels of the
organisation. The classification of Information Systems can be done on the basis of business functions
also. This classification is done to achieve the maximum efficiency in business functions. There are lot
many considerations we have to bother while we do business. The role played by the Internet and
Information Technologies to support electronic commerce, enterprise communications and collaboration,
and Web-enabled business processes both within a networked enterprise, and with its customers and
business partners will definitely require specialised Information Systems for Business functions.
Information systems can be grouped into business function categories; however, in the real world
information systems are typically integrated combinations of functional information systems. Functional
business systems are composed of a variety of types of information systems (transaction processing,
management information, decision support, etc) that support the business functions of:
• Accounting
• Finance
• Marketing
• Productions/operations management
• Human resource management
There is a strong emphasis in many organizations to develop such composite or cross-functional

information systems that cross the boundaries of traditional business functions in order to reengineer and
improve vital business processes. These organizations view cross-functional information systems as a
strategic way to share information resources and improve the efficiency and effectiveness of a business,
thus helping it attain its strategic objectives.
Business firms are turning to Internet technologies to integrate the flow of information among their
internal business functions and their customers and suppliers. Companies are using the World Wide Web
and their intranets and extranets as the technology platform for their cross-functional and
Interorganizational information systems.
Let us review some foundation concepts which will help us to understand the detailed explanation of
these systems.
E-Business Systems describes how information systems integrate and support enterprise-wide business
processes and the business functions of marketing, manufacturing, human resource management,
accounting, and finance.

Functional Business Systems - Functional business information systems support the business functions
of marketing, production/operations, accounting, finance, and human resource management through a
variety of e-business operational and management information systems.
Marketing - Marketing information systems support traditional and e-commerce processes and
management of the marketing function. Major types of marketing information systems include interactive
marketing at e-commerce websites, sales force automation, customer relationship management, sales
management, product management, targeted marketing, advertising and promotion, and market research.
Thus, marketing information systems assist marketing managers in electronic commerce product
development and customer relationship decisions, as well as in planning advertising and sales promotion
strategies and developing the e-commerce potential of new and present products, and new channels of
distribution.
Manufacturing - Computer-based manufacturing information systems help a company achieve

computer-integrated manufacturing (CIM), and thus simplify, automate, and integrate many of the
activities needed to quickly produce high-quality products to meet changing customer demands. For
example, computer-aided design using collaborative manufacturing networks helps engineers collaborate
on the design of new products and processes. Then manufacturing resource planning systems help plan
the types of resources needed in the production process. Finally, manufacturing execution systems
monitor and control the manufacture of products on the factory floor through shop floor scheduling and
control systems, controlling a physical process (process control), a machine tool (numerical control), or
machines with some humanlike work capabilities (robots).
Human Resources Management - Human resource information systems support human resource
management in organizations. They include information systems for staffing the organization, training
and development, and compensation administration. HRM websites on the Internet or corporate intranets
have become important tools for providing HR services to present and prospective employees.
Accounting and Finance - Accounting information systems record, report, and analyze business
transactions and events for the management of the business enterprise. Examples of common accounting
information systems include order processing, inventory control, accounts receivable, accounts payable,
payroll, and general ledger systems. Information systems in finance support financial manager in
decisions regarding the financing of a business and the allocation of financial resources within a
business. Financial information systems include cash management, online investment management,
capital budgeting, and financial forecasting and planning.
Cross-Functional Enterprise Systems - Many e-business applications are integrated cross-functional

enterprise applications like enterprise resource planning (ERP), customer relationship management
(CRM), and supply chain management (SCM), which also reengineers the business processes involved.
Enterprise collaboration systems (ECS) support and enhance communication and collaboration among the
teams and workgroups in an organization.
These systems themselves are being interconnected with enterprise application integration (EAI) software
so that the business users of these applications can more easily access the information resources they need
to support the needs of customers, suppliers, and business partners.
Transaction Processing Systems - Online transaction processing systems play a vital role in e-
commerce. Transaction processing involves the basic activities of (1) data entry, (2) transaction

processing, (3) database maintenance, (4) document and report generation, and (5) inquiry processing.
Many firms are using the Internet, intranets, extranets, and other networks for online transaction
processing to provide superior service to their customers and suppliers.
23.2 Sales and Marketing Information Systems
The business function of marketing is concerned with the planning, promotion, and sale of existing
products in existing markets, and the development of new products and new markets to better serve
present and potential customers.
As part of planning process, in order to produce superior value and satisfaction for customers, marketing
managers need information at almost every turn. They need information about:
• customers
• end-users
• resellers
• competitors,
• government regulations
• other forces in the marketplace
A marketing information system (MkIS) consists of people, equipment, and procedures to gather, sort,
analyse, evaluate, and distribute needed, timely and accurate information to marketing decision makers.
MkIS distributes information to managers in the right form and at the right time to help them make better
marketing decisions MkIS consists of people, equipment, and procedures to gather, sort, analyse,
evaluate, and distribute needed, timely and accurate information to marketing decision makers. It
distributes information to managers in the right form and at the right time to help them make better
marketing decisions.
Activities or Functions of Marketing Information Systems
• Assessing Information Needs

• Developing Information
o Internal records
o Marketing Research is consisting of Procedures to gather and analyse information for
marketing decision making. The focus is on new information not already available in
the MIS or in other secondary data sources. MR may be handled inside the firm or by
outside specialists.
• Information Analysis
• Distributing Information
Marketing information systems integrate the information flow required by many marketing activities.
Marketing information systems provide information for:
• Internet/intranet web sites and services make an interactive marketing process possible where
customers can become partners in creating, marketing, purchasing, and improving products
and services.

• Sales force automation systems use mobile computing and Internet technologies to automate
many information processing activities for sales support and management.
• Other marketing systems assist marketing managers in product planning, pricing, and other
product management decisions, advertising and sales promotion strategies, and market
research and forecasting.
Interactive Marketing
The explosive growth of Internet technologies has had a major impact on the marketing function. The
term interactive marketing has been coined to describe a type of marketing that is based on using the
Internet, intranets, and extranets to establish two-way interaction between a business and its customers or
potential customers. The goal of interactive marketing is to enable a company to profitably use those
networks to attract and keep customers who will become partners with the business in creating,
purchasing, and improving products and services.
• Customers are not passive participants, but are actively engaged in a network-enabled
proactive and interactive process.
• Encourages customers to become involved in product development, delivery, and service
issues.
• Enabled by various Internet technologies, including chat and discussion groups, web forms
and questionnaires, and e-mail correspondence.
• Expected outcomes are a rich mixture of vital marketing data, new product ideas, volume
sales and strong customer relationships.
Targeted Marketing
Targeted marketing has become an important tool in developing advertising and promotion strategies for
a company’s electronic commerce websites. Target marketing is an advertising and promotion
management concept that includes five targeting components:
• Community – companies can customize their web advertising messages and promotion methods
to appeal to people in specific communities. These can be communities of interest, such as
virtual communities of online sporting enthusiasts or arts and crafts hobbyists, or geographic
communities formed by the websites of a city or local newspaper.
• Content – advertising such as electronic billboards or banners can be placed on various website
pages, in addition to a company’s home page. These messages reach the targeted audience.
• Context – advertising appears only in web pages that are relevant to the content of a product or
service. So advertising is targeted only at people who are already looking for information about a
subject matter that is related to a company’s products.
• Demographic/Psychographic – marketing efforts can be aimed only at specific types or classes
of people: unmarried, twenty-something, middle income, and male college graduates.
• Online Behavior – advertising and promotion efforts can be tailored to each visit to a site by an
individual. This strategy is based on “web cookie” files recorded on the visitor’s disk drive from
previous visits. Cookie files enable a company to track a person’s online behavior at a website so
marketing efforts can be instantly developed and targeted to that individual at each visit to their
website.

Sales Force Automation
Increasingly, computers and networks are providing the basis for sales force automation. In many
companies, the sales force is being outfitted with notebook computers that connect them to Web
browsers, and sales contact management software that connect them to marketing websites on the
Internet, extranets, and their company intranets. Characteristics of sales force automation include:
• Increases the personal productivity of salespeople.

• Dramatically speeds up the capture and analysis of sales data from the field to marketing
managers at company headquarters.
• Allows marketing and sales management to improve the delivery of information and the
support they provide to their salespeople.
• Many companies view sales force automation as a way to gain a strategic advantage in sales
productivity and marketing responsiveness.
Customer Relationship Management (CRM)
By keeping the customer in the center of all the processes, a state of the art CRM will fulfill several goals.
First, it should enhance customer experience by delivering a personalized service no matter which
interaction channel is chosen. Second, it will assist the employees to bring a better service, providing
them with a broad and consolidated view on customer profile and relationship. Third, it helps the
management to capture and analyze customer behavior, to provide metrics for customer segmentation and
further supplies input for Decision Support Systems. Customer care and handling processes are
systematized and marketing budgets can be optimally allocated to target specific groups. On the long term
CRM will allow to maximize the customer life time value of each relationship where relationship is not
the sum of punctual sales of poorly related products anymore but turns to the delivery of a consistent
value proposition accompanying the customer in every stage of his life.
23.3 Manufacturing Information Systems
Manufacturing information systems support the production/operations function, which includes all
activities concerned with the planning and control of the processes that produce goods or services. The
production/operations function is concerned with the management of the operational systems of all
business firms. Information systems used for operations management and transaction processing support
all firms that must plan, monitor, and control inventories, purchases, and the flow of goods and services.
Information system helps in these manufacturing activities:
• Plant activity scheduling

• Material requirement assessment
• Material reallocation between orders
• Dynamic inventory management
• Grouping work orders by "characteristics"
• Resource qualification for task completion
Computer-Integrated Manufacturing (CIM)

Computer-based manufacturing information systems use several major techniques to support computer-
integrated manufacturing (CIM). CIM is an overall concept that stresses that the goals of computer use
in factory automation must be to:
• Simplify - (reengineer) production processes, product designs, and factory organization as a

vital foundation to automation and integration.
• Automate - Production processes and the business functions that support them with
computers, machines, and robots.
• Integrate - All production and support processes using computers, telecommunications
networks, and other information technologies.
Overall goal of CIM: - Is to create flexible, agile, manufacturing processes that efficiently produce
products of the highest quality. Thus, CIM supports the concepts of:
• Flexible manufacturing systems

• Agile manufacturing
• Total quality management
Results of CIM: - Implementing such manufacturing concepts enables a company to quickly respond to
and fulfil customer requirements with high-quality products and services.
Uses of computers in manufacturing include:
• Computer-aided engineering (CAE)

• Computer-aided design (CAD)
• Computer-aided process planning (CAPP)
• Material requirements planning (MRP)
• Manufacturing resource planning (MRP-II)
• Computer-aided manufacturing (CAM)
Computer-aided manufacturing - (CAM) systems are those that automate the production process. For
example, this could be accomplished by monitoring and controlling the production process in a factory
(manufacturing execution systems) or by directly controlling a physical process (process control), a
machine tool (machine control), or machines with some humanlike work capabilities (robots).
Manufacturing execution systems - (MES) are performance monitoring information systems for factory
floor operations. They monitor, track, and control the five essential components involved in a production
process:
• Materials
• Equipment
• Personnel
• Instructions and specifications
• Production facilities.
MES includes:
• Shop floor scheduling and control systems

• Machine control systems

• Robotics control systems
• Process control systems
Some of the benefits of CIM are:
• Increased efficiency through:

work simplification and automation,
better production schedule planning
better balancing of production workloads in production capacity
• Improved utilization of facilities, higher productivity, better quality control through:
continuous monitoring
feedback and control of factory operations, equipment and robots.
• Reduced investments in production inventories and facilities
work simplification
just-in-time inventory policies
better planning and control of production
better planning and control of finished goods requirements
• Improved customer service

reducing out-of-stock situations
producing high-quality products that better meet customer requirements
Process Control: the use of computers to control an ongoing physical process. Process control
computers are used to control physical processes in such areas as:
• Petroleum refineries
• Food product manufacturing plants
• Cement plants
• Pulp and paper mills
• Steel mills
• Electrical power plants
• Chemical plants
Machine Control: the use of a computer to control the actions of a machine. This is also popularly
called numerical control. The control of machine tools in factories is a typical numerical control
application, though it also refers to the control of typesetting machines, weaving machines, and other
industrial machinery.
Machine control computers are used in such areas as:
• Factories
• Industrial shops
• Machine tooling shops
Let us see some of the important subsystems of Manufacturing Information Systems and its functions.

Materials Requirement Planning (MRP)
• Take customer demand as initial input

• Number of product units needed and when they are needed
• Use long-range forecasts to put long-lead material on order
• Help reduce inventory cost while ensuring availability
Manufacturing Resource Planning (MRP II)
• MRP - Forecast and purchase of raw materials

• Assignment of jobs to personnel
• Assignment of manufacturing and assembly machinery
Combines MRP with other manufacturing-related activities to plan the manufacturing process such as
• Shop activity control and purchasing

• Source of demand
• Customer order entry and forecasting
• Support functions such as financial management, sales analysis, and data collection
In brief, Computer Integrated Manufacturing (CIM) is a technology, tool or method used to

improve entirely the design and manufacturing process and increase productivity which use computers to
help people and machines to communicate. It involves a series of integrated activities and operations
involving the design, materials selection, planning, production, quality assurance, management and
marketing of discrete consumer and durable goods. It is the integration of computer aided design,
automatic material handling, robotics, process technologies, manufacturing planning & control, computer
aided test, computer aided manufacturing. It focuses on the computer as the center of control of the entire
factory, starting from the computerization of the fabrication and assembly processes to the information
flow for production control, quality, maintenance, material handling, and inventory control in a totally
integrated system.
We will see the other Functional Information Systems in the next session as the continuum of
these discussions.

UNIT IV
Lesson 25 – Enterprise Information Systems II
Learning Objectives
1. To understand the use of Information Systems in various business processes

2. To learn about Human Resource Information Systems and Financial Information Systems
3. To study the role of IS in Cross-functional systems and Enterprise Information Systems
24.1 Human Resource Information Systems (HRIS)
For years, human resources were dependent upon paper documentation and administrative record-
keeping. Human resources retained their traditional duties with little significant change in how those
duties were performed. Recently, a preponderance of new processes and technologies has revolutionized
how human resource practitioners perform their jobs. The emergence of information and management
systems has been integral to this revolution.
A human resources information system (HRIS) is a system of software and supporting computer
hardware specifically designed to store and process all HR information. Also known as HRMS, human
resources management systems or less commonly, HRIMS, these systems are the mainstay of modern HR
departments. Traditionally, human resources departments relied on multiple programs in each department.
An HRIS integrates all of these programs through a common database and single-user interface. An HRIS
combines separate HR systems into a centralized database that performs the majority of HR transactions.
HRIS are particularly useful for payroll and benefits administration.
A sophisticated HRIS will simplify transactions, automate administrative tasks, and minimize
paperwork. It provides a consolidated database to coordinate self-service technologies. Employee self-
services such as intranets, kiosks, and voice response systems (VRUs) are dependent upon an HRIS to be
effective. Through system integration, an HRIS will reduce duplication and error while improving access
to employee information.
HRIS are increasingly considered a necessary component of HR because of the increasingly

global perspective of businesses. The combination of new technology and the subsequent loss of physical
boundaries requires comprehensive HR systems that can maintain one database while incorporating a
diversity of additional systems and capabilities.
The human resource management (HRM) function involves the recruitment, placement, evaluation,
compensation, and development of the employees of an organization. The goal of HRM is the effective
and efficient use of the human resources of a company. Thus, human resource information systems are
designed to support:
o Planning to meet the personnel needs of the business.

o Development of employees to their full potential.
o Control of all personnel policies and programs.
Traditionally, businesses used computer-based information systems to:

o Produce pay checks and payroll reports

o Maintain personnel records
o Analyze the use of personnel in business operations.
Many firms have gone beyond these traditional personnel management functions and have developed
human resource information systems (HRIS) that also support:
o Recruitment, selection and hiring

o Job placement
o Performance appraisals
o Employee benefit analysis
o Training and development
o Health, safety, and security
HRM and the Internet: The Internet has become a major force for change in human resource
management. For example, companies are:
o Recruiting for employees through recruitment sections of their corporate web sites.
o Using commercial recruiting services and databases on the World Wide Web, posting
messages in selected Internet newsgroups, and communicating with job applicants by
Internet e-mail.
HRM and the Corporate Intranet Intranet technologies allow companies to process most common
HRM applications over their corporate intranets. For example:
o Intranets allow the HRM department to provide around-the-clock services to their

customers – the employees.
o Intranets allow for the dissemination of valuable information faster than through
previous company channels.
o Intranets can collect information online from employees for input to their HRM files
o Intranets enable employees to perform HRM tasks with little intervention by the
HRM department.
o Intranets can serve as a superior training tool.
o Intranets enable employees to produce automated pay checks, the online alternative
to timecards.
Staffing the Organization: The staffing function must be supported by information systems that record
and track human resources within a company to maximize their use. These systems are used in personnel
record keeping systems, employee skills inventory systems, and personnel requirements forecasting
systems. Examples:
o Personnel record keeping system keeps track of additions, deletions, and other
changes to the records in a personnel database.
o Changes in job assignments and compensation, or hiring and terminations
o Employee skills inventory system that uses the employee skill data from a personnel
database to locate employees within a company who have the skills required for
specific assignments and projects.

o Forecasting personnel requirements to assure a business an adequate supply of high-

quality human resources.
Training and Development:
Information systems help human resource managers:
o Plan and monitor employee recruitment, training, performance appraisals, and career
development by analyzing the success history of present programs.
o Analyze the career development status of each employee to determine whether
development methods such as training programs and periodic performance
appraisals should be recommended.
The potential for efficiency presented by an HRIS can be significant. Because an HRIS automates the
bulk of transactional work, HR staff have increased time to perform strategic functions.
24.2 Accounting Information Systems
Accounting information systems are the oldest and most widely used information systems in business.
Computer-based accounting information systems:
• Record and report the flow of funds through an organization on a historical basis and produce
important financial statements such as balance sheets and income statements.
• Produce forecasts of future conditions such as projected financial statements and financial
budgets.
• Operational accounting systems focus on transaction processing systems. They emphasize
legal and historical record-keeping and the production of accurate financial statements.
Typically, operational accounting systems include:
o Order processing
o Inventory control
o Accounts receivable
o Accounts payable
o Accounts payroll
o General ledger systems.
• Management accounting systems focus on the planning and control of business operations.
They emphasize:
o Cost accounting reports
o Development of financial budgets and projected financial statements
o Analytical reports comparing actual to forecasted performance.
You will have heard the term "double entry book keeping". This is an old established system of
bookkeeping which forms the basis of all accounting systems. Today, of course, companies of all sizes
usually use computerised accounting systems. Nevertheless, it is useful to learn a little about the double
entry system as this will help you understand how a trial balance is drawn up.
Every "transaction" is supported by a business document. What do you understand by the term
"transaction", and which documents are we talking about? I have listed some of the most common

transactions below. Most transactions are related to the sale or purchase of goods, services, capital items
and consumables.
If you are a seller and make a sale:

• You produce an invoice.
• You send the top copy of the invoice to the buyer.
• You retain the second copy of the invoice
If you are a buyer and make a purchase
• The seller produces an invoice
• You receive the top copy of the invoice
• The seller retains the second copy of the invoice.
If you are a seller who has goods returned:
• You produce a credit note.
• You send the top copy of the credit note to the buyer.
• You retain the second copy of the credit note.
If you are a buyer who returns some goods
• The seller produces a credit note.
• You receive the top copy of the credit note.
• The seller retains the second copy of the credit note.
In this way everybody receives a document as a record of the transaction.
When purchasing capital items you will receive the top copy of the seller's invoice. In addition,
you may also receive a deed (for premises) or a formal hire purchase agreement. When purchasing small
quantities of consumables or other small items the document you will receive could be the till receipt.
Alternatively, the proprietor may make out and sign an internal petty cash voucher to release the money
from the petty cash account.
Let us see some of the important subsystems of Accounting Information Systems as follows.
Online Accounting Systems: Accounting information systems are being affected by Internet and
client/server technologies. Using the Internet, intranets, extranets, and other network changes how
accounting information systems monitor and track business activity. The online, interactive nature of
such networks calls for new forms of transaction documents, procedures, and controls. Many companies
are using or developing network links to their trading partners through the use of the Internet or other
networks for applications such as order processing inventory control, accounts receivable, and accounts
payable.
Order Processing: Order processing, or sales order processing, is an important transaction processing
system that captures and processes customer orders and produces data needed for sales analysis and
inventory control. In many firms, it also keeps track of the status of customer orders until goods are
delivered. Computer-based sales order processing systems:
• Provide a fast, accurate, and efficient method of recording and screening customer orders and
sales transactions.
• Provide inventory control systems with information on accepted orders so they can be filled
as quickly as possible.

Inventory Control: Inventory control systems process data reflecting changes to items in inventory. A
computer-based inventory control system:
• Record changes to inventory levels and prepares appropriate shipping documents.

• May notify managers about items that need reordering and provide them with a variety of
inventory status reports.
• Helps a business provide high-quality service to customers while minimizing investment in
inventory and inventory carrying costs.
Accounts Receivable: Accounts receivable systems keep records of amounts owed by customers from
data generated by customer purchases and payments. Accounts receivable systems:
o Produce invoices to customers, monthly customer statements and credit management

reports.
o Stimulate prompt customer payments by preparing accurate and timely invoices and
monthly statements to credit customers.
o Provide managers with reports to help them control the amount of credit extended
and the collection of money owed.
o Help to maximize profitable credit sales while minimizing losses from bad debts.
Accounts Payable: Accounts payable systems keep track of data concerning purchases from and
payments to suppliers. Accounts payable systems:
o Prepare checks in payment of outstanding invoices and produce cash management

reports.
o Help ensure prompt and accurate payment of suppliers to maintain good
relationships, ensure a good credit standing, and secure any discounts offered for
prompt payment.
o Provide tight financial control over all cash disbursements of the business.
o Provide management with information needed for the analysis of payments,
expenses, purchases, employee expense accounts, and cash requirements.
Payroll: Payroll systems receive and maintain data from employee time cards and other work records.
Accounts payable systems:
o Produce paychecks and other documents such as earning statements, payroll reports,
and labor analysis reports
o Product reports for management and government agencies.
o Help businesses make prompt and accurate payments to their employees, as well as
reports to management, employees, and government agencies concerning earnings,
taxes, and other deductions.
o Provide management with reports analyzing labor costs and productivity.
General Ledger: General ledger systems consolidate data from accounts receivable, accounts payable,
payroll, and other accounting information systems. General ledger systems:

o At the end of each accounting period, these systems produce the general ledger trial
balance, the income statement and balance sheet of the firm, and various income and
expense reports for management.
o Help businesses accomplish accounting tasks in an accurate and timely manner.
o Typically provide better financial controls and management reports and involves
fewer personnel and lower costs than manual accounting methods.
Newer technologies play an important role in improving the effectiveness of internal financial
information. For example, the cost-volume-profit (CVP) analysis technique and other methods of
analyzing costs and margins give management the subtle information it needs to make short- to medium-
term financial decisions. Activity-based costing (ABC) opens up a whole new approach to matching costs
and resources to their true causes. A state-of-the-art financial information system lays the foundation for
consistent and reliable reporting, regardless of the way the company analyzes the information.
24.3 Financial Management Systems
Computer-based financial management systems support financial managers in decisions concerning:
• The financing of a business.

• The allocation and control of financial resources within a business.
Major financial information system categories include:
• Cash and investment management.

• Capital budgeting
• Financial forecasting
• Financial planning
Cash Management: Cash management systems collect information on all cash receipts and
disbursements within a company on a real-time or periodic basis. Cash management systems:
• Allow businesses to deposit or invest excess funds more quickly, and thus increase the
income generated by deposited or invested funds.
• Produce daily, weekly, or monthly forecasts of cash receipts or disbursements (cash flow
forecast) that are used to spot future cash deficits or surpluses.
• Mathematical models frequently can determine optimal cash collection programs and
determine alternative financing or investment strategies for dealing with forecasted cash
deficits or surpluses.
Online Investment Management: Many businesses invest their excess cash in short-term low-risk
marketable securities or in higher return/higher risk alternatives, so that investment income may be earned
until the funds are required. Portfolio of securities can be managed with the help of portfolio
management software packages. Online investment management services:
• Are available from hundreds of online sources on the Internet and other networks.
• Help a financial manager make buying, selling, or holding decisions for each type of security
so that an optimum mix of securities is developed that minimizes risk and maximizes
investment income for the business.

Capital Budgeting: The capital budgeting process involves evaluating the profitability and financial
impact of proposed capital expenditures.
• Long term expenditure proposals for plants and equipment can be analyzed suing a variety of
techniques. This application makes heavy use of spreadsheet models that incorporate present
value analysis of expected cash flows and probability analysis of risk to determine the
optimum mix of capital projects for a business.
Financial Forecasting and Planning: A variety of financial forecasting packages provide analytical
techniques that result in economic or financial forecasts of national and local economic conditions, wage
levels, price levels, and interest rates.
Financial Planning systems use financial planning models to evaluate the present and projected financial
performance of a business or of one of its divisions or subsidiaries. Financial planning systems:
• Help determine the financial needs of a business and analyze alternative methods of financing
the business.
• Use financial forecasts concerning the economic situation, business operations, types of
financing available, interest rates, and stock and bond prices to develop an optimal financing
plan for the business.
• Frequently use electronic spreadsheet packages and DSS generators to build and manipulate
models.
• Are used to answer what-if and goal-seeking questions in order to evaluate financial and
investment alternatives.
Internal financial reporting traditionally means compiling and distributing generic reports that show a
company's past, short-term financial performance. The financial reports at one company look the same as
they would at any other company. And the information leaves management without insight, unable to link
what happened yesterday with how the company will meets its financial targets of tomorrow.
Best Practices
Best practices in the area of providing financial information can be quite technical and complex.
For example, the best practices address the fundamental assumptions and structure of internal financial
reporting, the selection of performance measures at the company, approaches to financial analysis, and
choices in the financial information system. As daunting as these best practices may appear, companies
should keep in mind that they have complete control and flexibility in the area of internal financial
reporting. After all, it is internal reporting, so it is completely up to the company to decide what serves it
best. In as much as these best practices are intricate and complex, a company in the end should select the
approaches and technologies that support its own decision-making process. A list of the best practices is
given below.
• Identify and understand the information needed by internal customers to execute the
business strategy, satisfy customers, and evaluate business process performance.
Once the finance group understands management's financial information needs, the next step
is to design, or redesign, the financial information systems to meet those needs. At this point,
most companies shift from the traditional focus on historical financial data, which provides

after-the-fact record keeping, to a new emphasis on information for decision making. For
example, reports that include activity-based costing, target costing, and life cycle costing link
financial performance with factors that affect revenues and expenses. These costing methods
also uncover trends in financial performance and indicate the effects of the current trends on
the company's attainment of strategic objectives.
• Measure and report profit contributed by appropriate segments, such as product line,
customer, channel, division, and geographic location.
Meaningful internal financial information differentiates profitable customers and business

segments from those that are not. To achieve this all-important goal, the company needs to
structure financial reports appropriately, so that recipients of the reports can plainly grasp the
profitability analysis. To collect the appropriate information to analyze, a company first needs
to identify how to segment its business to reflect the flow of profits, such as by market
segment, by distribution channel, by customer, or by division. Then the company assigns to
each segment the appropriate revenues, variable costs, and fixed costs. For example, for a
channel profitability analysis, costs would include channel management costs; channel
maintenance costs; advertising, promotion, and marketing costs; trade show costs; and
marketing staff costs. Through assigning the relevant revenues and costs to the business
segments, the company may identify high-profit and high-loss segments, and then set
objectives for avoiding costs relevant to high-loss segments.
• Integrate financial analysis with operational and industry analyses to identify

opportunities for improving business performance.
Many companies could use more sophistication in their financial reporting, with techniques
such as analysis of ratios and comparisons to industry and peer performance. These
techniques give management insight into where the business may be vulnerable and where it
might enjoy unique strengths. However, it's easy to go overboard with sophisticated financial
analysis techniques; keeping the measures simple and relevant to strategic business issues is a
reliable, powerful course of action.
Companies that apply best practices select a small number of key financial statistics and
ratios to watch closely, keeping in mind the company's circumstances and objectives. Ratios
and statistics are more meaningful if evaluated in terms of their trends over time. To broaden
the focus of financial analysis, high-performance companies compare their numbers to those
of competitors and best-of-class performers.
The balanced scorecard approach to financial reporting is particularly powerful. For a

balanced scorecard, the company selects a short list of measures that not only indicates the
operational and financial health of the business, but also its level of customer satisfaction and
the creative health of the business. An example of a balanced scorecard is one that chooses
measures that focus on four critical issues:
• The customer perspective: how do customers see the company?

• The internal business perspective: what must the company excel at?
• The innovation and learning perspective: can the company continue to improve and
create value?

• The financial perspective: how does the company look to shareholders?
Taking a balanced scorecard approach, a company creates performance measures to track all
levels of the company that reflect these four critical issues. For example, on periodic internal
reports, customer satisfaction metrics and statistics on the number of employees participating
in coursework are reported right alongside finance and operations numbers. To create
meaningful report content, employees from finance, operations, and other functional areas
need to collaborate with one another.
• Use cost-volume-profit analysis, contribution margins, and relevant costs and

qualitative factors to evaluate business opportunities.
Methods such as cost-volume-profit analysis, contribution margin calculation, and relevant

cost calculation help a company to evaluate the impact of expected changes in the volume of
sales on resulting costs and profits.
Special business opportunities require a company to look at short-term financial issues -- such
as revenues, expenses, and cash flow -- as opposed to long-term financial issues such as
equity distribution and indebtedness. Also, when evaluating special opportunities, in addition
to looking at the numbers, companies need to consider qualitative factors. Market
expectations and customer expectations should always play a role in a company's decision to
accept a one-time special order or to outsource its core business. Will existing customer
schedules be affected? Will the company lose expertise in a key skill area? Are there hidden
costs, like training and supervising time, that do not appear in the original analysis?
• Use the attributes of world-class financial information systems to evaluate and improve
the company's existing financial information systems.
At the foundation of effective internal financial reporting is a robust information system that
collects and disseminates information flexibly and reliably. Best practices companies study
the attributes of a world-class information system and look for computer hardware, software,
and systems design for their business that deliver these attributes:
• Standardized: the system captures and processes information consistently throughout the
company
• Complete: the system handles the information requirements of diverse groups of users
• Appropriate: the information is relevant, predictive, exception oriented, and at the right
level of detail
• Unified: the system has information links to customers and suppliers, and changes to data
in one area move through the whole system
• Flexible: applications may be tailored to the company's needs
• Cost-effective: the system makes efficient use of hardware and software licenses
• Easy to use: all types of users are comfortable with the system
• Timely: the system provides information when it's needed
• Ensure that key decision makers understand the strengths and weaknesses of internal
financial information.

Internal information has its limitations. The information is more meaningful and relevant
when decision makers understand its limits, how it is produced, and how it can help them.
The finance group can assist management in understanding internal financial information by
explaining the processes that underlie it. For example, the finance group can explain how the
financial system measures, records, and classifies transactions; how the finance group
periodically summarizes and reports financial information; and the meaning and limitations
on interpreting the information. One limitation of internal information is its bias toward
analyzing the past and focusing on short-term profitability. Another is its tendency to focus
on issues important only to the company, opposed to issues of concern to customers as well.
• Provide accurate and reliable activity-based cost information for resource allocation
decision making.
Activity-based costing (ABC) is a powerful tool that companies use to determine which activities
contribute to profitability. The concept of ABC is to distill a company's production process into a
set of activities and then attribute and analyze costs by activity. With ABC, a company sees
which activities cause its costs.
Implementing ABC lets a company allocate resources based on critical activities; eliminate
redundant activities and costs; eliminate activities that do not add value to the customer; set
budget levels in accordance with activities that cause costs; and place more reliable information
on activities and processes into the hands of management.
24.4 Cross-Functional Enterprise Systems
Cross-functional enterprise applications are integrated combinations of information subsystems that share
information resources and support business processes across the functional units of the business enterprise
and extend beyond to customers, suppliers, and other business partners.
Many organizations are using information technology to develop integrated cross-functional enterprise
systems that cross the boundaries of traditional business functions in order to reengineer and improve
vital business processes all across the enterprise. These organizations view cross-functional enterprise
systems as a strategic way to use IT to share information resources and improve the efficiency and
effectiveness of business processes, thus helping an e-business attain its strategic objectives.
Information systems typically are integrated combinations of cross-functional business systems. Such
systems support business processes, such as:
• Product development
• Production
• Distribution
• Order management
• Customer support Etc.
Enterprise Application Architecture

Enterprise Application architecture translates the logical design into a physical structure that
includes hardware, software, network support, and processing methods. The end product of the systems
design phase is the preparation of the system design specification document

Enterprise Application Integration
Many companies have moved from functional mainframe legacy systems to integrated cross-functional
enterprise applications. This typically has involved installing:
• Enterprise resource planning (ERP) software

• Supply chain management (SCM) software
• Customer relationship management (CRM) software
These cross-functional enterprise software applications focus on supporting integrated clusters of business
processes involved in the operations of a business.
Enterprise application integration (EAI) software is becoming available, which interconnects these
enterprise application clusters. EAI software:
• Enables users to model the business processes involved in the interactions that should occur
between business applications.
• Provides middleware that performs data conversion and coordination, application
communication and messaging services, and access to the application interfaces involved.
• Integrate a variety of enterprise application clusters by letting them exchange data according
to rules derived from the business process models developed by users.
• Integrate the front-office and back-office applications of an e-business, so they work together
in a seamless, integrated way. This is a vital capability that provides real business value to an
e-business enterprise that must respond quickly and effectively to business events and
customer demands.
Enterprise Collaboration Systems
Enterprise collaboration systems provide tools to help us collaborate - to communicate ideas, share
resources, and coordinate our cooperative work efforts as members of the many formal and informal
process and project teams and workgroups that make up many of today’s organisations.
The goal of enterprise collaboration systems is to enable us to work together more easily and effectively
by helping us to:

• Communicate - sharing information with each other

• Coordinate - coordinating our individual work efforts and use of resources with each other
• Collaborate - working together cooperatively on joint projects and assignments
Tools for Enterprise Collaboration
Electronic communication tools include electronic mail, voice mail, bulletin board systems, and faxing.
They enable you to electronically send documents and files in data, text, voice, or multimedia form over
computer networks. This helps you share everything from short voice and text messages to copies of
project documents and data files with your team members.
Electronic Conferencing Tools helps people communicate and collaborate while working together. A
variety of conferencing methods enable the members of teams and workgroups at different locations to
exchange ideas interactively at the same time, or at different times at their convenience. Electronic
conferencing options also include electronic meeting systems, where team members can meet at the same
time and place in a decision room setting.
Collaborative Work Management Tools help people accomplish or manage group work activities. This
category of groupware includes:
• Calendaring and scheduling tools

• Task and project management
• Workflow systems
• Knowledge repositories

UNIT IV
Lesson 26 – Tutorial on Enterprise Information Systems
Dear Students, after understanding about the various level information systems in the organisation
and the functional information systems, let us check and verify our knowledge by analyzing the following
case.
Case: Crystalline Entities
According to the sign on the building, Crystalline Entities (CE) (a fictional company) was founded
in 1895 by Hugo Salazar. In reality, the company was started in 1957 by Denise Luzon to import crystal
glass figurines and china plates for sale in the United States. Hardly anyone who works at the company today
remembers that Denise was really responsible for the creation and initial success of the company, and that
irritates John Balrun, the current CEO. Denise retired years ago and the firm is now a publicly traded
company with annual sales of about $20 million. John has been CEO for seven years. All but one of the vice-
presidents have been hired within the last five years. The VP of finance, Martha Vaniche, has been with the
company almost as long as John. Because of turnover, most of the 342 employees at the corporate offices are
younger and have worked there an average of about three years.
The company is organized in a traditional hierarchy by business function (marketing, accounting and
finance, production and purchasing, distribution, and human re-sources). About 15 years ago, CE bought
several small manufacturers in Ireland and Spain. These firms make up about 15 percent of current
production. They are located in small towns with low labor costs and are run independently by local
managers. The local managers know their employees personally and emphasize quality production. Items
that don’t pass the quality inspections are either destroyed or sold to local buyers. The other 85 per-cent of
the production is purchased from a variety of companies around the world. Quality is maintained by
inspecting all shipments and by dropping suppliers who cause problems.
Although there are many products, there are three basic types of sales. First, many of the products
are given as gifts (especially for weddings and anniversaries). These purchases are typically made through
department and specialty stores. The second type of sale consists of add-on and replacement pieces that
complement or complete a set. Many of these items are sold as special orders that are placed by customers
through the department stores. Occasionally customers will order pieces directly from CE. The third type of
sale is through various factory outlet stores. These stores are scattered across the country and typically offer
out-of-date items for 20 to 30 percent discounts. The stores are independently owned, and CE offers them
substantial discounts whenever they wish to drop certain pat-terns and clear their warehouse.
Core Products
The core products are crucial to Crystalline Entities. By keeping costs down, and by offering lower
prices and special packages, CE uses the core products to capture market share. As a result, the core products
represent about 60 percent of the total sales, but only 15 percent of the profits. The special orders are
considerably more profitable and make up about 70 percent of the total profits. Miscellaneous products and
impulse purchases make up the rest of the sales. When CE experienced decreasing sales growth 15 years ago,
the decline not only hurt current profits but also sales for the next three years because of lost sales of
specialty items for matching sets.

Going back to the early days of the company, Denise decided that it was best to focus on a few core
products. To compete against the established companies she wanted to offer good-quality crystal and
porcelain products at a lower price than the competitors. Her deception about the age of the company was
deliberately used to build an image of an established, high-quality company without spending much money.
To keep management costs down, the company was organized to emphasize decentralized decisions.
Products were ordered in bulk from overseas producers with low labor costs. The core items were stocked in
inexpensive warehouses. Marketing consisted of making regular visits to department and specialty stores and
convincing managers to carry the CE products. When buyers became convinced of the quality and compared
prices to existing brands, sales increased. As sales increased it became easier to convince additional stores to
carry the products. Corporate profits increased and the company expanded. About 15 years ago, the company
ran out of new markets and experienced major growing pains. Budgets were cut, staffing was slashed, and
the company searched for new ways to increase profits.
At some point, CE began experimenting with new designs and items that were aimed at impulse
purchases. The goal was to increase sales by capitalizing on the CE reputation for good-quality products at
reasonable prices. Today, there are two basic categories of products: a core group of styles and patterns that
is always in stock, and temporary or experimental items and china or crystal patterns. CE guarantees that the
core items will always be available so that customers can expand their sets or replace broken items.
When the company experienced the decline in sales, management decided to recommit the company
to providing high-quality products at lower costs than the competition. As part of that strategy, they decided
the best way to hold costs down was to keep management operations as simple as possible. Hence, the
various operations were delegated to de-centralized departments. Marketing consists mainly of contacting
department store buyers and processing orders that are sent to the distribution department. Marketing also
produces rough sales forecasts for the next quarter. These reports are based on comments by salespeople and
focus on categories of products (crystal, core products, experimental, special orders, and miscellaneous
products). The reports are sent to production and senior management. New designs are sent to production and
purchasing for final approval and to estimate the production costs. Every month, basic accounting numbers
on costs are sent to the ac-counting department.
Business Function Responsibilities
Purchasing and production focus on quality and are responsible for finding low-cost production
facilities that can produce large quantities of standardized products. Production reports and schedules are sent
to the marketing department every month, with quarterly summaries sent to management. Quarterly
production cost and profit numbers are sent to the accounting department for the quarterly financial reports.
On the purchasing side, purchase orders are sent to accounting, with monthly summaries sent to marketing.
When the manufacturer ships products, the company includes an invoice and also sends a separate shipping
list to the distribution warehouses.
The distribution department is responsible for transporting the products, storing them in warehouses,
and delivering the appropriate items to each store. Costs are kept under control by billing retail stores for
freight charges. Each warehouse manager has control over which products are sold at a discount to factory
outlet stores. When products have been around too long, they are offered to outlet stores at whatever price
they can get. Each warehouse produces a quarterly inventory report and a monthly list of sales to outlet
stores. Both reports are sent to marketing, which sends them on to accounting. When products arrive at the
warehouse, a receiving list is created that is sent to purchasing which cross checks the list with the supplier

shipping lists. Weekly reports of items shipped from the warehouse to stores is sent to accounting which
handles the billing.
Finance and accounting create traditional quarterly statements that are distributed to the other
departments and to management. Accounts receivable send bills to customers and records payments. All of
the financial records are stored on the IBM AS/400. Analysis of some of the reports and taxes are processed
on the personal computers.
Existing Computer Facilities
As a result of the decision to simplify management of the firm, each department tends to operate
independently of the others. Basic financial and personnel data is collected by accounting and finance to
produce quarterly and annual reports. The MIS department consists of three people who work in the
accounting department. The midsize IBM AS/400 computer records orders from the department stores, basic
payroll data, inventory, and standard financial data. It produces traditional accounting statements and other
basic re-ports for the government. Accounting and human resources use the computer most often.
All of the VPs and most of the managers have personal computers on their desks that are attached via
a LAN to the AS/400, giving them access to the basic reports. The personal computers are also used to write
memos and perform simple calculations using spreadsheets. The LAN is used by some employees for e-mail
messages.
Currently, around 1400 stores are regular customers of CE. They typically place one or two orders a
week for core products and miscellaneous new items. On average, CE receives about 800 orders a day for
specialty items. Most orders are filled and shipped within three working days. Orders are generally shipped
from the nearest warehouse. There are five warehouses scattered across the United States—all in low-wage
and low-rent areas. Occasionally, when a warehouse does not have enough items, the warehouse manager
will call the other warehouses and have them ship the product. Orders, shipment invoices, and billing are
handled by the computer. The accounting department uses the data to track ac-counts receivable. Because of
the volume of data, the orders and shipping invoices are moved to tape backup every month and removed
from the online system. Only the basic order data (date, buyer, totals, etc.) are kept on the system.

The design department in marketing has a small network of computers to help the group with art
designs. Many of the patterns and colors are created with graphics packages. Some people do initial designs
on paper and scan them into the computer to experiment with variations and different colors. Members of the
design department actively use their network to share ideas and pieces of designs. Although their smaller
LAN is also connected to the central computer, there has been little reason for them to use the central
computer.
Choosing Core Products
The issue of core products causes considerable friction within the company. Every year, the
designers introduce new patterns, and they want to place them in the core group. It is a personal status
symbol for the workers to have their designs placed in the permanent collection. Yet, the company cannot
afford to have thousands of different patterns in the core group, because it would require a huge inventory.
On the other hand, some items the core group has not sold very well for many years. Every year, there is a
meeting among all the VPs and departmental managers to decide which products should be included in the
core group. These meetings often degenerate into arguments and shouting matches. Lately, John Balrun has
noticed that the younger staff members and VPs seem to be join together and yelling at him and Martha. The
accountants have supported the decision to hold the core products stable and to hold costs down. The
marketing department suggests it would be better to increase sales by offering more products.
It seems that the arguments and political negotiations have started early this year. Several managers
have been circulating a memo complaining that the finance and accounting departments refuse to cooperate
with the designers. Jan Dover, the head of the design department, is complaining that the group can’t get
sales figures for each of the new patterns. They want also want to track sales of the core patterns during the
last few years to see which ones could be dropped. The designers are claiming that the accounting
department refuses to furnish the data.
John Balrun initially dismissed Jan’s complaint, because there has been consider-able antagonism
between her and Martha. John suspects that Jan’s memo is just a political ploy to gain attention before the
annual design meeting. However, it seems that Jan went to the MIS department with her request for
additional information. The MIS department complained to John saying the staff are already overworked.
They say CE will need a new faster computer, a massive increase in disk space, and at least two new
programmer analysts to do the initial work requested by Jan. John called a meeting with Jan, Martha, the
head of accounting, and the MIS members. At the meeting, the MIS group stated that it was impossible to
provide the data re-quested by the design team. The only data that was kept for more than a year were the
basic financial and accounting statements. These statements provide summary values for sales by category,
but not for each design pattern. In fact, the only detail records that might be available on backup tapes were
production data and some inventory figures for the last couple of years. After considerable discussion of the
experimental patterns, it was decided that it was impossible to obtain accurate sales figures. At best, the only
numbers available were orders and shipments to the retail stores. Occasionally, the CE sales people submit
informal reports on which items they believe are selling well, and which ones are sitting the shelves.
Someone at the meeting suggested using final inventory levels at the ware-house as an indicator of how well
products were selling. However, the distribution managers have control over the size of the warehouse
inventories. Sometimes a product sells well when it is introduced and the managers load the warehouses, but
then have a high inventory at the end of the year. In other cases, the warehouse manager might have already
unloaded weak-selling items to a factory outlet at a discount price. To keep costs under control, the
warehouse managers record outlet sales only by category, which is not itemized by pattern and color.

The designers now accept that the data they want is not available to make design decisions this year.
However, they have stated that they want to change the current system so that they can make better decisions
next year. John Balrun does not know where to start. It appears that most of the data does not exist. Plus, it
looks as if any attempt to change the current system will go against the fundamental goals of Crystalline
Entities provide quality crystal, porcelain, and china at prices below those of the competition.
Case Questions
1. Can MIS help Crystalline Entities? In particular, is it possible to get the data requested by the
designers?
2. What system problems exist?
3. What level (operations, tactical, strategic) is the primary source of problems?
4. Diagram the flow of data through the organization.
5. Devise improvements that will solve the basic problems of Crystalline Entities. Include an
implementation plan.
6. What resistance do you expect to encounter? How can it be minimized or overcome?
7. Is it possible to satisfy the designers and keep the essential goals of the company?

26.1 Introduction
Managers help keep chaos to a minimum. We've all worked for the person who proves this theory
wrong, but when all is said and done, minimizing chaos is the manager's number one job.
An organization's success is built around its managers, but also relies on technical competence,
adaptability to its environments, and a thorough knowledge of its product and production processes. Some
companies seem to "get it," while others companies just seem to get lost! Why? Management is the
answer: management of the employees, management of the product, and management of information.
Three Schools of Management
Let's take a close look at the three schools of management (technical-rational perspective,
behavioral, and cognitive), and see how they fit into different organizations. As we discuss the
management theories you should concentrate on how they would use various information system
configurations to enhance their characteristics.
The Technical-Rational Perspective
The technical-rational or classical perspective basically views people as machines. The

manager's job is to keep the machine running smoothly and in concert with all the other machines. The
manager is also responsible for creating an administration that keeps the machine well-oiled and fixes any
broken parts.
Henri Fayol's classic theory of management says managers perform five distinct functions:
• Planning
• Organizing
• Coordinating
• Deciding
• Controlling
In order to fulfill each of these functions, a manager must communicate. Think about it. If a manager
devises a plan, doesn't she have to tell someone what that plan is? If the manager coordinates a new plan,
doesn't he have to communicate with someone about the new plan? If the manager makes a decision,
doesn't someone have to know what that decision is?

The evolution of management theory
The people a manager communicates with, regardless of the action, are all around him/her. They could be
at a lower or higher management level. They could be inside or outside the organization. It doesn't matter.
The role of information systems, using the technical-rational perspective, is to improve the mechanical
operation of the organization.
Behavioral Perspective
We all know that humans aren't machines. They don't work in isolation from other humans, and
there are many more factors to take into consideration when managing humans rather than machines. The
behavioral perspective takes these important characteristics into account. Just as humans are living,
breathing, ever-changing beings, so too are organizations.
The manager's role is to assist the organization in continually changing and adapting to its environment.
This management theory gives you insight into the use of information systems to enhance the
effectiveness of the organization. It has had a powerful influence on the field of information systems:
• User acceptance literature emphasizes the sociological and psychological aspects of the
system success.
• Strategic IS literature emphasizes the importance of responding to and dominating the
environment.

• Network organization and virtual organization literature emphasizes organizing labor without
traditional hierarchies.
Managerial Roles: Mintzberg
In his research, Mintzberg found that managerial roles fell into three categories:
• Interpersonal. Managers act as representatives of the organization to internal and external

audiences.
• Informational. Managers pass information up and down and around the organization.
• Decisional. Once managers make a decision, they must pass it on to someone else. But before
they can make that decision, they have to gather information from internal/external sources.
How Managers Get Things Done: Kotter
Kotter argues that managers are always looking out for themselves. They establish agendas and
goals, build interpersonal networks, and then execute their own personal agendas.
What Managers Decide: Wrapp
Wrapp's theory of management describes managers not as dictators but as guides. They guide the
people and the organization as a whole toward consensus goals. They understand that no part of the
organization can work in isolation from other parts and that it takes the whole team to win the game.
The Cognitive Perspective and Postmodern Era
To be successful, the cognitive perspective says an organization must create and use information
to its utmost advantage. The organization must gather, create, store, disseminate, and use information and
knowledge. The effective manager will make sense of the situation, help the organization act in its best
interest, and create the proper infrastructure for information- and knowledge-processing to the advantage
of the organization.
This management theory has evolved in and from the computer revolution of the last few decades
as information systems proliferated and improved. The organization can now get a better sense of its
environment, internal and external, and how to create and use information through and from the Internet.
Managerial Sense-making

Managerial sense-making
Managerial sense-making is the philosophy of managers properly defining a situation for both the
employees and the organization. The old adage “Let’s make sense of it all” is the operative words. Some
managers are more successful at this than others. As depicted in the above figure, the successful manager:
• Creates knowledge structures by filtering information from the environment. Not every tidbit
of information is worthwhile.
• Solves problems and makes decisions. If the manager is successful, then the organization
triumphs.
• Processes information. The information may be internal or external.
• Creates information-processing structures, programs, and routines. The manager decides what
information is needed based on his/her definition of the situation.
The Knowledge-Based View of the Firm
Managerial sense-making focuses on the individual manager. The knowledge-based view focuses
on the organization's ability to gather, produce, maintain, and disseminate knowledge. Some
organizations require more intense information and knowledge gathering in order to produce their
products and services than others. For instance, the Research and Development department of a candy
manufacturer has more need for knowledge-based information systems than would the Production
Department. That's not to say the Production Department has no need for knowledge or for information,
but its tasks are less dependent on knowledge-based systems and more dependent on transaction
processing systems.
Regardless of the management model followed, managers spend most of their time
communicating: listening, talking, reading, and writing. The use of email technology allows managers to
complete more communications than ever before. They can also employ other methods of technology that

increase the amount of communicating they do. Remember the Human Resources Department policy on
dress codes that the HR manager posted to the Intranet? Communication at its finest!
26.2 Introduction to Decision Making
Everybody makes decisions. It's a natural part of life, and most of the time we don't even think
about the process. In an organization, decisions are made at every level. The level at which the decision is
made can also determine the complexity of the decision in relation to the input of data and output of
information.
Levels of Decision Making
In the previous units, we discussed the various types of Information Systems and how they relate to
the levels of an organization. We can also relate those Information Systems to the types of decisions
managers make.
• Strategic Decision Making. These decisions are usually concerned with the major objectives
of the organization, such as "Do we need to change the core business we are in?" They also
concern policies of the organization, such as "Do we want to support affirmative action?"
• Management Control. These decisions affect the use of resources, such as "Do we need to
find a different supplier of packaging materials?" Management-level decisions also determine
the performance of the operational units, such as "How much is the bottleneck in Production
affecting the overall profit and loss of the organization, and what can we do about it?"
• Knowledge-Level Decision Making. These decisions determine new ideas or improvements
to current products or services. A decision made at this level could be "Do we need to find a
new chocolate recipe that results in a radically different taste for our candy bar?"
• Operational control. These decisions determine specific tasks that support decisions made at
the strategic or managerial levels. An example is "How many candy bars do we produce
today?"
Types of Decisions: Structured versus Unstructured
Some decisions are very structured while others are very unstructured. You may wake up in the
morning and make the structured, routine decision to get out of bed. Then you have to make the
unstructured decision of what clothes to wear that day (for some of us this may be a very routine
decision!). Structured decisions involve definite procedures and are not necessarily very complex. The
more unstructured a decision becomes, the more complex it becomes.
Types of Decisions and Types of Systems

Information systems support different decisions at different organization levels
One size does not fit all when it comes to pairing the types of systems to the types of decisions.
Every level of the organization makes different types of decisions, so the system used should fit the
organizational level, as shown in the above figure.
It's easy to develop an information system to support structured decision making. Do you increase
production on the day shift or hold it to the swing shift; do you purchase another piece of equipment or
repair the old one? What hasn't been so easy to develop is a system that supports the unstructured decision
making that takes place in the upper echelons of a company. Do we expand into foreign markets or stay
within the confines of our own country; do we build a new plant in Arizona or Alabama; do we stop
production of a long-time product due to falling demand or boost our marketing? The ability to create
information systems to support the latter decisions is long overdue.
Stages of Decision Making
Some people seem to make sudden or impulsive decisions. Other people seem to make very slow,
deliberate decisions. But regardless of appearances, the decision-making process follows the same stages
of development and implementation. Let's use the example of purchasing a new television, using the
following figure.

The decision-making process
• Intelligence. You identify the facts: You don't have a television or the one that you do have
isn't any good. You intuitively understand what the problem is and the effect it's having on
you. You missed your favorite show last night.
• Design. You design possible solutions: You could watch the television in your neighbor's
apartment or you could purchase a new one for yourself. Your neighbor will get annoyed if
you keep coming over. On the other hand, you won't be able to go on vacation if you use your
money to buy a new television.
• Choice. You gather data that helps you make a better decision: Your neighbor doesn't like the
same shows you like or she's getting rather tired of you being there. You also determine that
televisions cost a lot of money so you figure out how you can afford one. You choose to
purchase a new television instead of watching your neighbor's.
• Implementation. You implement the decision: You stop at the appliance store on your way
home from work and carry out your decision to purchase a new television.
• Feedback. You gather feedback: You're broke but you can watch anything you want!
Of course this is a simplified example of the decision-making process. But the same process is
used for almost every decision made by almost every person.
Information Systems help improve the decision-making process by
• providing more information about the problem

• presenting a greater variety of possible alternatives

• showing consequences and effects of choices

• measuring the outcome of different possible solutions
• providing feedback on the decision that is made
Different types of decisions require different types of systems. All decisions follow the same
pattern although some may be more complex and require several iterations of the decision-making stages.
26.3 Individual Models of Decision Making
No matter how much you know, you can't possibly know everything. No one can possibly know
all the input to a decision, process all the possible outcomes, and know every output from the final
decision. Neither can an Information System. However, it can gather more input, process it faster, and
output more alternatives than a human can.
What a machine can't do is make decisions in context. That could be a positive aspect or a
drawback. Humans make decisions based on experience and in very distinct ways based on their frame of
reference. For instance, some people won't buy a certain type of television because they haven't had "good
luck" with that brand before. Based on their experience, they choose a different alternative than another
person would. Some people will do careful, extensive research into all the possible models of televisions
and make a decision based on that data. Some people will purchase the same brand as the one they
already have. Others simply walk into the store and point to the model they want.
The Rational Model
The rational model of human behavior says that people will evaluate the situation and determine
what they want the result to be. They will determine the alternative courses of action, know the
consequences of each course, and then pick the course with the biggest payoff. If it were only that easy!
Think about some of the decisions you've made recently. Did you have an absolutely clear understanding
of the situation and know exactly what you wanted the end result to be? Probably not if you did not
evaluate the decision closely and thoroughly. Did you examine every possible solution? Probably not. Did
you fully comprehend the consequences of every possible solution? Not likely. Was there only one
possible outcome to your decision or were there several?
Bounded Rationality and Satisficing
Sometimes people will follow the rational model to a certain extent, with a lot of compromising
throughout the decision-making process, by using bounded rationality. That is, they will look at several
alternatives, briefly evaluate the consequences of the alternatives, and then pick the solution that will get
them closest to where they want to be (satisficing). If they've experienced a similar situation, they'll
probably go with the decision most like the previous decision.
Muddling Through
Compromise is a very common occurrence in decision-making. Your club needs to raise dues to
pay for a new piece of equipment. Some of your members don't want to purchase the equipment and
others want the best brand on the market. A spirited discussion takes place with each side presenting
conflicting opinions. After a while, you agree to purchase a used piece costing only half of the original
price. You muddled through the decision-making process until everyone agreed on the solution. As it
turns out, the decision was similar to one made several years before. By following the previous decision,
your group practiced incremental decision making.

Psychological Types and Frames of Reference
The cognitive style theory supports the idea that people make decisions based on their
experiences and values. Why are there so many different types and styles of automobiles and trucks?
After all, isn't the basic idea of owning a vehicle simply a matter of how you get from one location to
another? Why do you choose a red car over a blue car? Why do some people own a pickup truck in the
heart of a major metropolitan area? Isn't the reason for owning a truck simply to haul things? Major
studies have confirmed that people decide the color of their vehicles based on personality type. People
choose the type of vehicle, car or truck or minivan, based on their experiences and psychological needs
more than for the absolute need for a particular type of transportation.
People are people. Sounds simplified and silly, but it's one of the best explanations for why
people make decisions the way they do. This lesson points that some people use a systematic decision-
making process, while others use an intuitive process. You could argue that one method is better than the
other, but it's an argument you could carry on forever.
26.4 Organizational Models of Decision Making
If it's tough for an individual to make a decision, think how hard it is in an organization with
many people all used to making decisions their way! The organizational decision-making process must
take into account the various wants and needs of the people who make up that organization. Let's look at
various models of organizational decision-making.
Bureaucratic Models
According to the bureaucratic model, the main goal of an organization is the preservation of the
organization itself. Change is very slow and difficult because the structure isn't designed for change.
Change causes uncertainty, and this type of organization isn't strong on changing anything.
Change is difficult in the bureaucratic organization because most use Standard Operating
Procedures to determine how tasks will be accomplished. These SOPs have developed over a long period
of time and are usually based on previous decisions and work habits. To some members of the
bureaucratic organization, changing the SOPs is to say that the previous methods were inferior or wrong.
That's not necessarily the case, since changing environments can bring the need for changing the
organization. Nonetheless, changing the bureaucratic organization is a slow and sometimes painful
process.
A word of caution: Everyone automatically associates "bureaucratic" with government

organizations. Private organizations can be just as interested in preserving their structure. Many private
companies could use some drastic changes and improvements, but they don't make them because they are
more interested in keeping the status quo.
Political Models of Organizational Choice
The decision-making process in the political model is based not necessarily on what's good for
the organization, but on what's good for the players involved. Compromise is more the norm than clear-
cut decisions. The goal of this type of organization is to blend the interests of the players into a decision
that satisfies as many people or entities as possible.

"Garbage Can" Model
Garbage can model sounds like a funny label, but it's very apt. "Oops" is the operative word in
this organization. Too often the people involved in this type of decision making process develop the
wrong answer to the wrong question. Any success is purely accidental.
26.5 How Information Technology Has Changed the Management Process
Times have changed and so have the methods by which managers make decisions. Information
technology has helped speed the change in methods.
Traditional and Contemporary Management
Technology has enabled companies to flatten their hierarchies. The last few years has seen an
exodus of middle managers. Companies simply didn't need the extra layers because of technological
advances that allow lower levels of employees to communicate and collaborate easier and faster than ever
before. Managers in these newly flattened organizations are now responsible for making sure employees
know the environmental influences on the organization, know the goals of the organization, and adjust the
organization to meet the new influences. Managers then free their employees to meet not only the
organization's goals, but also their personal goals.
Information systems can help managers and employees work more efficiently and effectively in
this new environment by increasing the amount of information available to all employees.
Communications are faster and more widespread with new technologies that enable employees and
managers to collaborate more closely and work better in teams. New information systems also enable
virtual organizations and geographically dispersed teams and groups to work together to meet personal
and organizational goals.
Implications for System Design
The decision-making process is much different in today's organization than it was just a few years
ago. The danger of building a system to accommodate today's process is that it will not take these changes
into account. Understanding how people and organizations make decisions will help build a system that
can accommodate the organization and the employees.
Information systems should be created not only to help mangers and employees make decisions,
but also help them better communicate between all levels and units of the organization. Remember,
decisions are not made in isolation.. More important, decisions affect a wide range of people, and the
system should accommodate this fact.
The real danger in using information systems to help make decisions is that the decision-making
process will be based on the wrong information. Because managers may assume that the situation is
similar to one they experienced before, they may not be as careful as they would be if it were an entirely
new situation. For instance, management may decide that the new packaging materials are as good as the
old ones because they are the same color.
Therefore managers won't be as careful in studying all the data, all the possible outcomes and the
alternatives when making the decision to change suppliers. They make the decision based on the first

available alternative that moves them toward their ultimate goal. They find out too late that the packaging
materials are not as good as the old ones and they end up with more damaged goods and irate customers.
Information systems should have these characteristics:
• They are flexible and provide many options for handling data and evaluating information.
• They are capable of supporting a variety of styles, skills, and knowledge.
• They are powerful in the sense of having multiple analytical and intuitive models for the
evaluation of data and the ability to keep track of many alternatives and consequences.
• They reflect the bureaucratic and political requirements of systems.
• They reflect an appreciation of the limits of organizational change and an awareness of what
information systems can and cannot do.
26.6 Summary
An organization must examine the theory it most closely follows and then design the information
system to fit. Above all, managers communicate. Make that process easier, cheaper, faster, and more
efficient and you've increased the worth of that manager tremendously. Increase the number of people and
entities the manager can communicate with, and you reduce the number of managers required.
You should remember that every decision causes change and that people react to change in many
different ways. Some people embrace change; others abhor it. But you can't make a decision without
causing a change somewhere.
Understanding how an organization makes decisions can help increase the success of the
decisions made.
Using information systems in the decision-making process should be a positive exercise. That is,
the system should help managers at all levels make better decisions, more efficiently, to the benefit of a
greater number of people, and to improve the organization.

UNIT V
Lesson 28 – Decision Support Systems (DSS)
Learning Objectives
1. To learn how managers can enhance their decision making

2. To know about the concept – DSS and its components
3. To study the various types of DSS and its functions
28.1 Introduction
The more information you have, based on internal experiences or from external sources, the better
your decisions. Business executives are faced with the same dilemmas when they make decisions. They
need the best tools available to help them.
Decision makers to make quality decisions should, to the best of their abilities:
1. thoroughly check a wide range of alternatives

2. gather full range of goals and implications of choices
3. weigh costs and risks of both positive and negative consequences
4. intensively search for new information for evaluating alternatives
5. take all new information into account, even when it doesn't support initial course of action
6. re-examine positive and negative consequences of all alternatives, including initially rejected
ones
7. make detailed provisions for implementation, including contingency plans for known risks
When we discussed Transaction Processing Systems and Management Information Systems, the
decisions were clear-cut: "Should we order more raw materials to support the increased production of our
product?" Most decisions facing executives are unstructured or semi-structured: "What will happen to our
sales if we increase our candy bar prices by 5%?"
Decision Support Systems (DSS) help executives make better decisions by using historical and
current data from internal Information Systems and external sources. By combining massive amounts of
data with sophisticated analytical models and tools, and by making the system easy to use, they provide a
much better source of information to use in the decision-making process.
Decision Support Systems (DSS) are a class of computerized information systems that support
decision-making activities. DSS are interactive computer-based systems and subsystems intended to help
decision makers use communications technologies, data, documents, knowledge and/or models to
successfully complete decision process tasks.
DSS and MIS
In order to better understand a decision support system, let's compare the characteristics of an MIS system
with those of a DSS system:
MIS DSS
Structured decisions Semistructured, unstuctured decisions

Reports based on routine flows of data Focused on specific decisions / classes of decisions
General control of organization End-user control of data, tools, and sessions
Structured information flows Emphasizes change, flexibility, quick responses
Presentation in form of reports Presentation in form of graphics
Greater emphasis on models, assumptions, ad hoc queries
Traditional systems development Develop through prototyping; iterative process
You can also understand the differences between these two types of systems by understanding the
differences in the types of decisions made at the two levels of management. Are your decisions routines,
or are your decisions nonroutines? You might find it helpful to review the information about decision-
making processes from the previous lesson.
28.2 Framework of Decisions Support Systems
A conceptual framework for Decision Support Systems (DSS) is developed based on the
dominant technology component or driver of decision support, the targeted users, the specific purpose of
the system and the primary deployment technology. Five generic categories based on the dominant
technology component are proposed, including Communications-Driven, Data-Driven, Document-Driven,
Knowledge-Driven, and Model-Driven Decision Support Systems. Each generic DSS can be targeted to
internal or external stakeholders. DSS can have specific or very general purposes. Finally, the DSS
deployment technology may be a mainframe computer, a client/server LAN, or a Web-Based architecture.
The goal in proposing this expanded DSS framework is to help people understand how to integrate,
evaluate and select appropriate means for supporting and informing decision-makers.
Because of the limitations of hardware and software, early DSS systems provided executives only
limited help. With the increased power of computer hardware, and the sophisticated software available
today, DSS can crunch lots more data, in less time, in greater detail, with easy to use interfaces. The more
detailed data and information executives have to work with, the better their decisions can be.
Need for an Expanded Framework
Decision Support Systems should be defined as a broad category of information systems for
informing and supporting decision-makers. DSS are intended to improve and speed-up the processes by
which people make and communicate decisions. We need to improve how we define Decision Support
Systems on both a conceptual level and on a concrete, technical level. Both managers and DSS designers
need to understand categories of decision support so they can better communicate about what needs to be
accomplished in informing and supporting decision makers.
The DSS literature includes a number of frameworks for categorizing systems. Steven Alter
(1980) developed the broadest and most comprehensive one more than 20 years ago. A new, broader
typology or framework than Alter’s (1980) is needed because Decision Support Systems are much more
common and more diverse than when he conducted his research and proposed his framework.
Decision Support Systems do vary in many ways. Some DSS focus on data, some on models and
some on communications. DSS also differ in scope, some DSS are intended for one "primary" user and
used “stand-alone” for analysis and others are intended for many users in an organization. A Decision

Support System could be categorized in terms of the generic operations it performs, independent of type
of problem, functional area or decision perspective. His seven types included: file drawer systems, data
analysis systems, analysis information systems, accounting and financial models, representational models,
optimization models, and suggestion models.
An Expanded Framework
The following expanded DSS framework is still evolving. The author and others have used the
framework to classify a large number of software packages and systems. Anecdotal reports indicate that
people who have tried to use it in describing a proposed or existing DSS have found it comprehensive,
useful and parsimonious. It seems to help one categorize the most common Decision Support Systems
currently in use. The framework focuses on one major dimension with 5 generic types of DSS and 3
secondary dimensions. The primary dimension is the dominant technology component or driver of the
decision support system; the secondary dimensions are the targeted users, the specific purpose of the
system and the primary deployment technology. Some DSS are best classified as hybrid systems driven
by more than one major DSS component.
28.3 Types of DSS
Data-Driven DSS
Data-Driven DSS take the massive amounts of data available through the company's TPS and
MIS systems and cull from it useful information which executives can use to make more informed
decisions. They don't have to have a theory or model but can "free-flow" the data.
The first generic type of Decision Support System is a Data-Driven DSS. These systems include
file drawer and management reporting systems, data warehousing and analysis systems, Executive
Information Systems (EIS) and Spatial Decision Support Systems. Business Intelligence Systems are also
examples of Data-Driven DSS. Data- Driven DSS emphasize access to and manipulation of large
databases of structured data and especially a time-series of internal company data and sometimes external
data. Simple file systems accessed by query and retrieval tools provide the most elementary level of
functionality. Data warehouse systems that allow the manipulation of data by computerized tools tailored
to a specific task and setting or by more general tools and operators provide additional functionality.
Data-Driven DSS with Online Analytical Processing (OLAP) provide the highest level of functionality
and decision support that is linked to analysis of large collections of historical data.
Model-Driven DSS
A second category, Model-Driven DSS, includes systems that use accounting and financial
models, representational models, and optimization models. Model-Driven DSS emphasize access to and
manipulation of a model. Simple statistical and analytical tools provide the most elementary level of
functionality. Some OLAP systems that allow complex analysis of data may be classified as hybrid DSS
systems providing modeling, data retrieval and data summarization functionality. Model-Driven DSS use
data and parameters provided by decision-makers to aid them in analyzing a situation, but they are not
usually data intensive. Very large databases are usually not needed for Model-Driven DSS.
Model-Driven DSS were isolated from the main Information Systems of the organization and
were primarily used for the typical "what-if" analysis. That is, "What if we increase production of our
products and decrease the shipment time?" These systems rely heavily on models to help executives
understand the impact of their decisions on the organization, its suppliers, and its customers.

Knowledge-Driven DSS
The terminology for this third generic type of DSS is still evolving. Currently, the best term
seems to be Knowledge- Driven DSS. Adding the modifier “driven” to the word knowledge maintains a
parallelism in the framework and focuses on the dominant knowledge base component. Knowledge-
Driven DSS can suggest or recommend actions to managers. These DSS are personcomputer systems
with specialized problem-solving expertise. The "expertise" consists of knowledge about a particular
domain, understanding of problems within that domain, and "skill" at solving some of these problems. A
related concept is Data Mining. It refers to a class of analytical applications that search for hidden patterns
in a database. Data mining is the process of sifting through large amounts of data to produce data content
relationships.
Document-Driven DSS
A new type of DSS, a Document-Driven DSS or Knowledge Management System, is evolving

to help managers retrieve and manage unstructured documents and Web pages. A Document-Driven DSS
integrates a variety of storage and processing technologies to provide complete document retrieval and
analysis. The Web provides access to large document databases including databases of hypertext
documents, images, sounds and video. Examples of documents that would be accessed by a Document-
Based DSS are policies and procedures, product specifications, catalogs, and corporate historical
documents, including minutes of meetings, corporate records, and important correspondence. A search
engine is a powerful decisionaiding tool associated with a Document-Driven DSS.
Communications-Driven and Group DSS
Group Decision Support Systems (GDSS) came first, but now a broader category of
Communications-Driven DSS or groupware can be identified. This fifth generic type of Decision
Support System includes communication, collaboration and decision support technologies that do not fit
within those DSS types identified. Therefore, we need to identify these systems as a specific category of
DSS. A Group DSS is a hybrid Decision Support System that emphasizes both the use of communications
and decision models. A Group Decision Support System is an interactive computer-based system
intended to facilitate the solution of problems by decision-makers working together as a group.
Groupware supports electronic communication, scheduling, document sharing, and other group
productivity and decision support enhancing activities We have a number of technologies and capabilities
in this category in the framework – Group DSS, two-way interactive video, White Boards, Bulletin
Boards, and Email.
Inter-Organizational or Intra-Organizational DSS
A relatively new targeted user group for DSS made possible by new technologies and the rapid
growth of the Internet is customers and suppliers. We can call DSS targeted for external users an Inter-
organizational DSS. The public Internet is creating communication links for many types of inter-
organizational systems, including DSS. An Inter-Organizational DSS provides stakeholders with access to
a company’s intranet and authority or privileges to use specific DSS capabilities. Companies can make a
Data-Driven DSS available to suppliers or a Model-Driven DSS available to customers to design a
product or choose a product. Most DSS are Intra-Organizational DSS that are designed for use by
individuals in a company as "standalone DSS" or for use by a group of managers in a company as a
Group or Enterprise-Wide DSS.
Function-Specific or General Purpose DSS

Many DSS are designed to support specific business functions or types of businesses and
industries. We can call such a Decision Support System a function-specific or industry- specific DSS. A
Function-Specific DSS like a budgeting system may be purchased from a vendor or customized in-house
using a more general-purpose development package. Vendor developed or “off-the-shelf” DSS support
functional areas of a business like marketing or finance; some DSS products are designed to support
decision tasks in a specific industry like a crew scheduling DSS for an airline. A task-specific DSS has an
important purpose in solving a routine or recurring decision task. Function or task-specific DSS can be
further classified and understood in terms of the dominant DSS component, that is as a Model-Driven,
Data-Driven or Suggestion DSS. A function or task-specific DSS holds and derives knowledge relevant
for a decision about some function that an organization performs (e.g., a marketing function or a
production function). This type of DSS is categorized by purpose; function-specific DSS help a person or
group accomplish a specific decision task. General-purpose DSS software helps support broad tasks like
project management, decision analysis, or business planning.
28.4 Components of DSS
Traditionally, academics and MIS staffs have discussed building Decision Support Systems in
terms of four major components:
• The user interface

• The database
• The models and analytical tools and
• The DSS architecture and network
This traditional list of components remains useful because it identifies similarities and differences
between categories or types of DSS. The DSS framework is primarily based on the different emphases
placed on DSS components when systems are actually constructed.
Data-Driven, Document-Driven and Knowledge-Driven DSS need specialized database components.
A Model- Driven DSS may use a simple flat-file database with fewer than 1,000 records, but the model
component is very important. Experience and some empirical evidence indicate that design and
implementation issues vary for Data-Driven, Document-Driven, Model-Driven and Knowledge-Driven
DSS.
Multi-participant systems like Group and Inter- Organizational DSS also create complex implementation
issues. For instance, when implementing a Data-Driven DSS a designer should be especially concerned
about the user's interest in applying the DSS in unanticipated or novel situations. Despite the significant
differences created by the specific task and scope of a DSS, all Decision Support Systems have similar
technical components and share a common purpose, supporting decision- making.
A Data-Driven DSS database is a collection of current and historical structured data from a
number of sources that have been organized for easy access and analysis.
We are expanding the data component to include unstructured documents in Document-Driven

DSS and "knowledge" in the form of rules or frames in Knowledge-Driven DSS. Supporting management
decision-making means that computerized tools are used to make sense of the structured data or
documents in a database.

Mathematical and analytical models are the major component of a Model-Driven DSS. Each
Model-Driven DSS has a specific set of purposes and hence different models are needed and used.
Choosing appropriate models is a key design issue. Also, the software used for creating specific models
needs to manage needed data and the user interface. In Model-Driven DSS the values of key variables or
parameters are changed, often repeatedly, to reflect potential changes in supply, production, the economy,
sales, the marketplace, costs, and/or other environmental and internal factors. Information from the
models is then analyzed and evaluated by the decision-maker.
Knowledge-Driven DSS use special models for processing rules or identifying relationships in
data. The DSS architecture and networking design component refers to how hardware is organized, how
software and data are distributed in the system, and how components of the system are integrated and
connected. A major issue today is whether DSS should be available using a Web browser on a company
intranet and also available on the Global Internet. Networking is the key driver of Communications-
Driven DSS.
Overview of a DSS
The DSS software system must be easy to use and adaptable to the needs of each executive. A
well-built DSS uses the models that the text describes. You've probably used statistical models in other
classes to determine the mean, median, or deviations of data. These statistical models are the basis of
datamining.
The What-If decisions most commonly made by executives use sensitivity analysis to help them
predict what effect their decisions will have on the organization. Executives don't make decisions based
solely on intuition. The more information they have, the more they experiment with different outcomes in
a safe mode, the better their decisions. That's the benefit of the models used in the software tools.
28.5 Examples of DSS Applications

Burlington Coat Factory Store location and inventory mix
National Gypsum Corporate planning and forecasting
Southern Railway Train dispatching and routing
Texas Oil and Gas Corporation Evaluation of potential drilling sites
United Airlines Flight scheduling
U.S. Department of Defense Defense contract analysis
28.6 Web-Based DSS
Of course, no discussion would be complete without information about how companies are using
the Internet and the Web in the customer DSS decision-making process. The following figure shows an
Internet CDSS (Customer Decision-Support System).
Customer decision support on the Internet
Here's an example: You decide to purchase a new home and use the Web to search real estate
sites. You find the perfect house in a good neighborhood but it seems a little pricey. You don't know the
down payment you'll need. You also need to find out how much your monthly payments will be based on
the interest rate you can get. Luckily the real estate Web site has several helpful calculators (customer
decision support systems) you can use to determine the down payment, current interest rates available,
and the monthly payment. Some customer decision support systems will even provide an amortization
schedule. You can make your decision about the purchase of the home or know instantly that you need to
find another house.

28.7 Summary
Executives make semi-structured and unstructured decisions based on historical and current data,
from both internal and external sources. Well-built Decision-Support Systems help them make better
decisions by making more of these kinds of data available in the decision-making process. Datamining is
one of the most effective tools for gathering useful information provided it's used properly. In addition to
data, the components of a DSS include effective software tools, and a user interface that is easy to use.
Decision-makers receive and analyze information using many different media, including
traditional print, group and interpersonal information exchanges, and computer based tools. One set of
computer-based tools has been termed Decision Support Systems. For more than 30 years, researchers
and Information Systems specialists have built and studied a wide variety of systems for supporting and
informing decision-makers that they have called Decision Support Systems or Management Decision
Systems.
In the past few years, some additional terms like business intelligence, data mining, on-line
analytical processing, groupware, knowledgeware, and knowledge management have been used for
systems that are intended to inform and support decision-makers. The new terms are imprecisely defined
and subject to marketing hyperbole. This proliferation of terms creates problems in conducting research
and in communicating with decision-makers about decision support systems. The solution is developing
an expanded and well-defined framework for categorizing decision support systems.
The terms framework, taxonomy, conceptual model and typology are often used interchangeably.
Taxonomies classify objects and typologies show how mutually exclusive types of things are related.
Frameworks provide an organizing approach and a conceptual model shows how ideas are related. The
general desire is to create a set of labels that help people organize and categorize information.

1. A marketing manager has asked you to help design a DSS for the marketing department. Every
month marketers need to evaluate the effectiveness of their advertising campaigns and decide
how to allocate their budget for the next month. They advertise only in the local area and have
four basic choices: radio, television, local newspapers, and direct mail. Each month, they conduct
random phone interviews to find out who sees their advertisements. They can also purchase local
scanner data to determine sales of related products. Each month, the media salespeople give them
the Arbitron ratings that show the number of people (and demographics) who they believe saw
each advertisement. They also receive a schedule of costs for the upcoming month. As a first step
in creating the DSS, identify any relevant assumptions and input and output variables, along with
any models that might be useful.
2. A government official recently noted that the government is having difficulty processing
applications for assistance programs (welfare). Although most applications are legitimate, several
facts they contain have to be checked. For instance, welfare workers have to check motor vehicle
and real estate records to see whether the applicants own cars or property. The agency checks
birth, death, and marriage records to verify the existence of dependents. They sometimes examine
public health data and check criminal records. It takes time to check all of the records, plus the
agency needs to keep track of the results of the searches. Additionally, a few applicants have
applied multiple times—sometimes in different localities. The office needs to randomly check
some applications to search for fraud. Every week, summary reports have to be sent to the state
offices. A key feature of these reports is that they are used to convince politicians to increase
funding for certain programs. Describe how a DSS could help this agency. Hint: Identify the
decisions that need to be made.

UNIT V
Lesson 29 – Group Decision Support Systems
Learning Objectives
1. To know the concept of GDSS and its application in decision making

2. To understand the need of GDSS and its Goals in the organisation.
3. To study about the tools used in GDSS
4. To know how GDSS can help managerial decision making better.
29.1 Introduction
Many business decisions involve a group of people. Often one person might be responsible for
the final decision, but meetings are used to enable everyone to have a say, analyse the potential effects on
each area, and persuade others to accept a decision. Decisions that involve groups of people have
additional complications. Someone has to organise and control the meeting. During the meeting, people
compete to make comments and get their options heard. Someone has to take notes of the meeting and
votes have to be counted.
Information systems can help with group decisions. Groupware tools can be used to share data
and documents. Message systems can be used to share comments and early drafts of work. Bulletin
boards can be used to let everyone express opinions and evaluations. In the late 1980’s, an additional tool
known as a group decision support systems (GDSS) was defined. A GDSS is designed to help managers
reach a consensus during meetings.
29.2 What is a GDSS?
More and more, companies are turning to groups and teams to get work done. Hours upon hours
are spent in meetings, in group collaboration, in communicating with many people. To help groups make
decisions, a new category of systems was developed--the group decision-support system (GDSS).
You've been there: a meeting where nothing seemed to get done, where some people dominated
the agenda and others never said a word, which dragged on for hours with no clear agenda. When it was
all over no one was sure what was accomplished, if anything. But the donuts and coffee were good!
Organizations have been struggling with this problem for years. They are now using GDSS as a
way to increase the efficiency and effectiveness of meetings. The text includes a list of elements that
GDSS use to help organizations. We'll highlight a few of them:
• Preplanning: A clear-cut agenda of the topics for the meeting.

• Open, collaborative meeting atmosphere: Free flow of ideas and communications without
any of the attendees feeling shy about contributing
• Evaluation objectivity: Reduces "office politics" and the chance that ideas will be dismissed
because of who presented them instead of what was presented
• Documentation: Clear communication about what took place and what decisions were made
by the group
• Preservation of "organizational memory": Even those unable to attend the meeting will
know what took place; great for geographically separated team members.

29.3 GDSS Characteristics and Software Tools
We're back to our triangle of
In GDSS the hardware includes more than just computers and peripheral equipment. It also
includes the conference facilities, audiovisual equipment, and networking equipment that connect
everyone. The persware extends to the meeting facilitators and the staff that keeps the hardware operating
correctly. As the hardware becomes more sophisticated and widely available, many companies are
bypassing specially equipped rooms in favor of having the group participants "attend" the meeting
through their individual desktop computers.
Many of the software tools and programs discussed, Groupware, can also be used to support GDSS.
Some of these software tools are being reworked to allow people to attend meetings through Intranets or
Extranets. Some highlights:
• Electronic questionnaires: Set an agenda and plan ahead for the meeting
• Electronic brainstorming: Allows all users to participate without fear of reprisal or criticism
• Questionnaire tools: Gather information even before the meeting begins, so facts and
information are readily available
• Stakeholder identification: Determines the impact of the group's decision
• Group dictionaries: Reduce the problem of different interpretations
Now instead of wasting time in meetings, people will know ahead of time what is on the agenda.
All of the information generated during the meeting is maintained for future use and reference. Because
input is anonymous, ideas are evaluated on their own merit. And for geographically separated attendees,
travel time and dollars are saved. Electronic meeting systems make these efficiencies possible. The
following figure shows the sequence of activities at a typical EMS meeting.

URE 15.6
Group system tools
All is not perfect with EMS, however. Face-to-face communications is critical for managers and
others to gain insight into how people feel about ideas and topics. Body language can often speak louder
than words. Some people still may not contribute freely because they know that all input is stored on the
file server, even though it is anonymous. And the system itself imposes disciplines on the group that
members may not like.
29.4 Features of GDSS
Most versions of GDSS use special meeting rooms where each participant is seated at a
networked computer. A facilitator operates the network and keeps the discussion moving in the right
direction. Before the meeting, the primary decision maker meets with the facilitator to establish the
objective of the meeting. They setup sample questions and design the overall strategy.
Typical meetings begin with a brainstorming session, where participants are asked to think of
ideas, problems and potential solutions. They type each of these into categories on their computers. The
basic ideas and suggestions are stored in a database and shared with the group through the networked
computers.
In terms of discussions and comments, the facilitator can choose individual items and project
them on the screen for the entire group to analyse. Participants can write comments or criticisms of any
idea at any time. This system is particularly helpful if many participants come up with many ideas and
comments at the same time. The computer enables everyone to enter comments at the same time, which is
faster than waiting for each person to finish speaking.
Another feature of using the computer for the entry of ideas and comments is that they can be
anonymous. Although each comment is numbered, they are not traced back to the original author, so
people are free to criticize their supervisor’s ideas. Anonymity reduces embarrassment and encourages
people to submit riskier ideas.
At various points, the facilitator can call for participants to vote on some of the ideas and
concepts. Depending on the software package, there can be several ways to vote. In addition to traditional
one-vote methods, there are several schemes where you place weights on your choices. The votes are

done on the computer and results appear immediately. Because it is so easy to vote, the GDSS encourages
the group to take several votes. This approach makes it easier to drop undesirable alternatives early in the
discussion.
One useful feature of conducting the meeting over a computer network is that all of the
comments, criticisms, and votes are recorded. They can all be pointed at the end of the session. Managers
can review all of the comments and add them to their reports.
In theory, a meeting could be conducted entirely on a computer network, saving costs and travel time if
the participants are located in different cities. Also, if it is designed properly, a GDSS can give each
participant access to the corporate data while he or she is in the meeting. If a question raises about various
facts, the computer can find the answer without waiting for a second meeting.
29.5 Why do we need GDSS?
• Many organizations use group or team structures to organize the work effort.
• Complex decisions often require more co-ordinated efforts and input of multiple individuals.
• Decision making is diffused throughout the organization.
• Information technology is a powerful tool to support the group decision making processes of
an organization.
29.6 Goals of GDSS
A. Mitigate the problems of group work.
• Social pressures of conformity may result in "groupthink".

• Lack of co-ordination of work and poor planning of meetings.
• Inappropriate influence of group dynamics.
• Tendency of group members to rely on others to do most of the work.
• Tendency toward compromised solutions of poor quality;
• Social "loafing"
• Tendency to repeat what was already said.
• Larger costs of making decisions.
• Tendency of group to take riskier decisions than they should.
• Incomplete or inappropriate use of information.
• Inappropriate representation in group.
B. Accentuate the Benefits of group work.
• Groups are better than individuals at understanding problems.

• Groups are better than individuals at catching errors.
• A group has more knowledge/information than any one member.
• Working in a group may stimulate the participants and the process.
• The participation of the members in a decision means less likelihood to resist
implementation.
• People are accountable for the decisions that they participate in.
C. Support multiple group processes.
• Generate ideas and alternatives

• Provide methods that aid the decision and judgment process

• Provide access to rules that will aid the choice between alternatives
• Provide methods for reconciling conflict.
29.7 How GDSS Can Enhance Group Decision Making
Go back to the previous list of problems associated with meetings and you can determine how
GDSS solve some of these problems.
1. Improved preplanning: Forces an agenda to keep the meeting on track.

2. Increased participation: Increases the number of people who can effectively contribute to the
meeting.
3. Open, collaborative meeting atmosphere: Nonjudgmental input by all attendees.
4. Criticism-free idea generation: Anonymity can generate more input and better ideas.
5. Evaluation objectivity: The idea itself is evaluated and not the person contributing the idea.
6. Idea organization and evaluation: Organized input makes it easier to comprehend the results
of the meeting.
7. Setting priorities and making decisions: All management levels are on equal footing.
8. Documentation of meetings: Results of meeting are available soon after for further use and
discussion.
9. Access to external information: Reduces amount of disagreements by having the facts.
10. Preservation of "organizational memory:" Information is available to other groups within the
organization.
You can see from this list that the potential for efficient and effective meetings is increased by
using GDSS to promote open and organized decision making in groups.
More and more, decisions are being made by groups in today's business environment. Most
meetings are inefficient. Using Group Decision Support Systems, comprised of hardware, software, and
people, helps streamline group meetings and communications by removing obstacles and using
technology to increase the effectiveness of the decisions.
29.8 Limitations of GDSS
Perhaps the greatest drawback to a GDSS is that it requires participants to type in their ideas,
comments and criticisms. Most people are used to meetings based on oral discussions. Even if they have
adequate typing skills, a GDSS can inhibit some managers.
Along the same lines, in a traditional meeting, only one person speaks at a time, and everyone
concentrates on the same issue at the same time. With a GDSS your focus is continually drawn to the
many different comments and discussions taking place at the same time. People who type rapidly and fit
from topic to topic will find that they can dominate the discussions.
In terms of costs, maintaining a separate meeting room with networked computers can be
expensive. Unless the facility is used on a regular basis, the computers will be idle a great deal of then
time. When you factor in the costs for network software, the GDSS software, and other utilities, the costs
multiply. One way to minimize this problem is to lease the facilities that have been established by a
couple of universities and some companies.
The use of GDSS also requires a trained facilitator – someone who can lead discussions, help
users, and control the GDSS software on the network. Hiring an in-house specialist can be very expensive
of there are only a few meetings a year. Again, using facilities are scrupulously honest; there might be
some topics that you do not want to discuss with non-employees.

One way to overcome these limitations is to alter the approach to the meetings. Instead of
requiring everyone to get together at the same time in on room, meetings could be held via network
discussion groups. Each participant could read the messages, add comments, and vote on issues
electronically at any time from any location. Again, the internet offers possibilities to provide these
facilities, but it could be a few years before organisations and managers can accept the changes required.
29.9 Summary
The GDSS started originally from the Management Information System at University of Arizona.
Some kind of problems has always been observed that are associated more with large meetings than with
small meetings. By large meetings we mean meetings with generally more than 15 participants, but can
go much beyond that, e.g. 40 or even 50. Some of the identified problems are:
• Time consuming;
• Dominance over the meeting; and
• Honesty and participation.
However, it is important to realize that we are not therefore trying to say that small meetings do
not have these above problems; these problems mentioned exist in any kind of meetings, but we are just
trying to stress that they are more commonly found in large meetings. Small meetings tend to be more
easily controlled than large meetings.
In a GDSS environment, there is usually a big room with something like 40 seats, which means
that 40 people can be at the meeting at any one time. There are not only 40 seats but also 40
microcomputers. This enables every participant to have the use of one microcomputer during the course
of the meeting. The reason why each participant needs a microcomputer depends on how GDSS works.
In the GDSS, with special computer software, the facilitator of each meeting will first make the
agenda of the meeting, which will be projected onto a big screen that everyone can see. Then the
participants will type simultaneously in their ideas of the topic of discussion on the individual
microcomputers next to them. Then the computer will sort the ideas, and then the participants will then
vote or comment on which ideas they like or they dislike. In the course of the whole meeting, GDSS
stores, categorizes and prints out all the ideas, comments and vote tallies, so that each of the meeting
participants will get a summary of the meeting when it ends.
What so special about GDSS is that it enables meeting participants to simultaneously "talk",
when the computer sorts and sends ideas to each of the terminal, all at the same time. That saves a
tremendous amount of time, because all these are done electronically instead of manually, and the time
saved will enable participants to spend more time manipulating and expressing their ideas. This can
consequently increase the productivity and efficiency of the group. The time-consuming benefit also has
an added bonus: when productivity and efficiency in meetings increase, it is likely that the team spirit can
be consolidated, resulting in an increase of the strength of binding among team members.
Besides, under this GDSS, no one can dominate the meeting. This is because of another feature of
GDSS. GDSS provides an anonymous scheme, so that whatever you type in the terminal (i.e. your
opinion) will be protected. Under this circumstance, no one really knows who is typing what. Because of
this, not a single person can dominate the meetings. In the worst case, we might say "some ideas" are
dominating the meeting, but this is perfectly fine because this is as a matter of fact an aim of the GDSS: to
help meeting participants voice their opinions from an idea-oriented mindset. For example, simply

because you have a prejudice against person A does not mean that you are going to reject the idea being
proposed in the meeting, because you do not know who is proposing that idea!!
Besides, this anonymity scheme will also help those team members who are shy to voice opinions. And
with the anonymity, people are likely to be more honest, just as you'll say more, and more honestly on the
professor's evaluation form if you know whatever you write will not affect your final grade on the course.
This, of course, is because you know you don't have to worry about the consequences.
However, whether this anonymity is good or not can be very controversial. The success of meetings
supported by GDSS depends largely on the conduct of the participants. If people are taking advantage of
the anonymity system by typing obscene words or foul languages, this system may be banned for the
good of the organization.

UNIT V
Lesson 30 - Executive Support Systems
Learning Objectives
1. To understand the role of Executive Support Systems in the organisation

2. To know the characteristics of the ESS
3. To study about the various interfaces available to ESS
4. To know the applications of ESS
30.1 Introduction
I think DSS was an interesting topic and you all still remembering a lot about DSS and it's
working. If you remember then most of the DSS users are professionals and middle managers like
financial analysts, loan officers, auditors, or production schedulers. However top executives use DSS very
rarely. Could you answer so? If yes then you already know the need of Executive support system. But I
feel that majority of people will have the answer no. So we need to know what the top executives
requirement is that is not provided by DSS. What top executives actually want their information and
support system to provide them? These are the questions and answers to them will make a framework for
executive support system.
Executive Support Systems (ESS) supply the necessary tools to senior management. The
decisions at this level of the company are usually never structured and could be described as "educated
guesses." Executives rely as much, if not more so, on external data than they do on data internal to their
organization. Decisions must be made in the context of the world outside the organization. The problems
and situations senior executives face are very fluid, always changing, so the system must be flexible and
easy to manipulate.
30.2 The Role of ESS in the Organization
Executives often face information overload and must be able to separate the chaff from the wheat
in order to make the right decision. On the other hand, if the information they have is not detailed enough
they may not be able to make the best decision. An ESS can supply the summarized information
executives need and yet provide the opportunity to drill down to more detail if necessary.
As technology advances, ESS are able to link data from various sources both internal and external
to provide the amount and kind of information executives find useful. As common software programs
include more options and executives gain experience using these programs, they're turning to them as an
easy way to manipulate information. Many executives are also turning to the Web to provide the
flexibility they need.
The Nature of Executive's Work
We now know the basics of ESS. Now before continuing further I want to discuss the nature of an
executives work. This means that which type of work executives normally do or perform for which they
require not a DSS but ESS. This is highly required before building an ESS. Because without the
knowledge of executives work we cannot decide about the system which is suitable for him.

Basically manager's role is divided into 3 categories

1. Interpersonal Role - Roles like figurehead, leader, and liaison
2. Informational roles - Roles of monitor, disseminator, spokesperson
3. Decisional roles - Entrepreneur, disturbance handler, resource alligator, negotiator.
Most of the ESS support all these roles for executive's successful working. If we pay attention
then we can see that for interpersonal roles and informational roles with very few advances to DSS the
executives can start using ESS. But executives mainly require the ESS for decisional roles. To determine
the information needs of executives, it is necessary to specify the activities, which are performed in
decisional role.
We divide the work of executives in relation to the decision roles into 2 phases. Phase 1 is the
identification of problems or opportunities. Phase 2 is the decision of what to do about it. The figure
below provides the flowchart that describes about the process of information flow in decisional roles.
Functional units like finance, production, accounting, and personnel etc. generate the internal
information. The external information comes from the sources such as online databases, newspaper,
industry newsletters, government reports, personal contacts etc. We know that the combined information
is very important because that is the source needed for successful competition and survival. As the data is
large the information is needed to be scanned further. The collected information is then checked and
verified for its correction that is it is evaluated for the further use of the organization. Finally the
evaluated information is sent for qualitative or quantitative analysis. Then the executive makes a decision
whether an opportunity occurs or problem occurs. If there is a problem then information is given as an
input for the next step else it is again scanned for further evaluation. Finally the executives take the
decision.
30.3 Developing ESS
As with DSS, executive support systems are developed using the prototyping method.
Prototyping allows iterative, quick changes to the system. Executives are busy people who don't want to
spend a lot of time in the development process. They know what they want, they want it quickly, and they
want it to work the first time. That's a tough goal for developers.
ESS must support many of the executive's informational requirements or she will find other ways
to supplement her decision-making tasks. If the system doesn't provide the flexibility to scout out
problems, new opportunities, or keep an eye on the competition, executives will ignore the system and
seek other ways of getting the information they need--mainly other people.
30.4 Benefits of ESS
As more executives come up through the ranks, they are more familiar with and rely more on
technology to assist them with their jobs. Executive Support Systems don't provide executives with ready-
made decisions. They provide the information that helps them make their decisions. Executives use that
information, along with their experience, knowledge, education, and understanding of the corporation and
the business environment as a whole, to make their decisions.
Executives are more inclined to want summarized data rather than detailed data (even though the
details must be available). ESS rely on graphic presentation of information because it's a much quicker
way for busy executives to grasp summarized information.

Because of the trend toward flatter organizations with fewer layers of management, companies
are employing ESS at lower levels of the organization. This trend will probably continue as more
managers become knowledgeable about the power and flexibility of ESS.
Advantages
• Simple for high-level executives to use Operations do not require extensive computer
experience
• Provides timely delivery of company summary information
• Provides better understanding of information
• Filters data for better time management
• Provides system for improvement in information tracking
Disadvantages
• Computer skills required to obtain results

• Requires preparation and analysis time to get desired information
• Detail oriented Provides detailed analysis of a situation
• Difficult to quantify benefits of DSS How do you quantify a better decision?
• Difficult to maintain database integrity
• Provides only moderate support of external data and graphics capabilities
30.5 Examples of ESS
The examples of ESS provided in the lesson offer interesting contrasts of how each organization
uses its system to aid in the decision-making process.
The Sutter Home Winery uses mostly external data, including information from the Internet, in its
ESS. It organizes the information in order to help executives make decisions based on trends in the
marketplace. The information includes data on competitors and information from market research. Sutter
uses its system output to determine sales forecasts, marketing campaigns, and investment plans.
Managers at the Royal Bank of Canada are able to choose their own criteria (from among 15
choices) to drill down and navigate data through easy-to-use interfaces. They don't have to accept data in
formats chosen by someone else who may not understand individual manager's needs. Data analysis is
more timely because the information is quicker to obtain and more convenient than before.
Virtually all of the information in the U.S. General Services Administration's ESS is internal data
used to help executives manage the government's assets and inventory of buildings. The information is
used for analysis of the efficient, or inefficient, use of buildings. The systems includes the ability to drill
down to more specific detail if necessary. Output includes graphs and pictures of the inventory. Huge
amounts of data are available quicker and are more specific to the user's needs.
I would like to explain more of ESS with the following industry problem which will give you a
better understanding.
30.6 ESS: A Better Example

We know that car industry is characterized by tough competition and fast-shifting opportunities.
One of such car industry was Hertz that needs to compete against dozens of competitors in hundreds of
locations. Now the company's key to success is marketing. Several marketing decision must be made
instantaneously. Some of such decisions can be
• Whether to give discount on product seeing other company's strategy. . Whether to give some
attractive gift with the product or not
• Whether to give free servicing for one year, free accessories or not. Whether to give
insurance policy or not
All these decisions are taken on daily basis based on the information about cities, climates,
holidays, business cycles, and tourist activities, past promotions and competitor and customer's behavior.
It is also necessary to know everyday the rental prices set by all competitors in all cities. This is a time -
consuming data collection task as the amount of information required is quite large and also it should be
very timely. This requires the use of large mainframe computers to process such huge quantity of data.
The problem for this car industry was how to provide accessibility to this information and use it properly.
The initial solution, which was implemented in 1987, was the use of DSS to allow fast analysis
by executives and managers. The DSS was good enough to analyze information but when the marketing
manager has some question he or she needs to contact the assistant staff for this purpose. This process,
which looks so simple, is quite complicated and problematic due to following reason
• The assistant staff is not always available
• There can be misunderstanding of concepts
• The process becomes quite lengthy in case of confusion a The information not timely
accessed most of the time.
These limitations made Hertz Company to think of a better and efficient system. which can be
used by Executives or senior managers. It was sure that this system is merely an extension to DSS so that
senior executives do not need to contact staff assistant and can access the data of there need themselves.
So the ESS was used as the front end to DSS. It was named as Executive information system or Executive
support system because of the purpose for which it was made. The ESS serves as an executive tool to
analyze the stored information and make real time decisions without the use of assistants or support staff.
The system is extremely user-friendly and is maintained by the marketing staff that continuously upgrades
and improves the system for their executives.
Executives on the other hand can manipulate and refine data to be more meaningful and
strategically more significant to them. Even the workload on the mainframe programming resources has
been (educed because ESS allows executives to draw information from the mainframe, store the needed
data on their own PC and take a decision. The most significant fact that executives were using ESS is
because it does all these work in real time (instantly).
So I would now like to remind the definition of executive support system. As with other IS this
also does not have any specific definition and is interpreted differently by different persons. So a general
definition of ESS is as follows.
An ESS (Executive support system) is a computer-based system that serves the information needs
to top executives. It provides rapid access to timely information and direct access to management reports.
ESS is very user-friendly, supported by graphics, and provides exceptions reporting and" drill-down"
capabilities. It is easily connected with online information services and electronic mail.

Some factors that contributed to the development of ESS are as follows. These are also the factors
that tell us why to use ESS for higher management.
Internal External
Need for timely information Increasingly competitive environment
Need for Improved
Rapidly changing environment

Need for access to operational

Need for rapid updates from Need to proactively approach external

30.7 Characteristics of ESS
An ESS has many distinct characteristics that differentiate it from other applications software. A
list of these features is presented in table below. A successful executive information system minimizes
hard copy reports while keeping high-level executives up dated. With an ESS, qualitative information is
obtained without producing volumes of paper.
Advanced internal control and communication are typical focuses of an ESS. The ability to view
exception reporting on the computer screen is an example of an ESS-facilitated management control
technique. Most Executive Support Systems highlight the areas of the business that are going astray.
Color codes are used to display data that are in an acceptable or unacceptable range as defined by the
executive. This technique allows the computet to track important project assignments within a company
using the executive information system. An ESS allows access to external as well as company internal
information.
Characteristics Description
Degree of use High, consistent, without need of technical assistance
Computer skills required Very low -must be easy to learn and use
Flexibility High - must fit executive decision making style
Principle use Tracking, control
Decisions supported Upper level management, unstructured
Data supported Company internal and external
Output capabilities Text, tabular, graphical, trend toward audio/video in future
Graphic concentration High, presentation style
Data access speed Must be high, fast response
30.8 Difference between ESS and DSS
Decision support systems, reflected to as DSS, are another type of computer information system
designed support and improve the decision-making process. Many more computer users will be familiar
with DSS because these systems were developed as a support tool for middle to lower level managers and
system analysts. Like the ESS, DSS are made up of several distinct components. While both types contain

a modeling capability and database component, the presentation components are typically not as
sophisticated in a DSS. The reason is that DSS were developed to support decisions from the middle level
up, while an ESS concentrates on supporting the very top level of management.
Although both ESS and DSS are designed to support and improve the decision-making process,
the actual type of decision an executive makes differs from that of a middle manager. The ESS can be
thought of as a system that provides information to help formulate intelligent queries, which can then be
passed on to the DSS. An analyst can then perform a detailed analysis, not an executive. The intention of
the ESS is to allow executives to familiarize themselves with the organization as a whole, and not just one
particular area. The DSS usually provides very detailed information to assist analysis of problems in one
section/department of a business. Another primary difference is the ability of an ESS to incorporate "what
if' models in the program. With this ability, the user can perform impact analyses, such as "What is the
effect on profits if we close Plant A." Another important difference is that external data retrieved from on-
line databases as well as internal data will be examined when answering a query to the ESS. The DSS
typically only places a moderate emphasis on incorporating external data into the decision process.
While each system tracks and reports the status of certain activities, the level of detail provided when a
problem occurs is vastly different. An ESS delivers primarily summary information. It allows for details
to be given by incorporating the "drilling down" capability. The DSS will attempt to provide all the
details incorporated into the problem analysis the first time.
30.9 ESS Applications
As stated previously, studies have shown that about one third of the largest corporations in the
United States have some kind of ESS installed or under installation. But just which companies are turning
to Executive Support Systems to enlighten their top managers? The following examples of ESS imple-
mentations highlight some of the more popular applications for this software product.
30.9.1 Manufacturing
• Hiram-walker Of Windsor, Ontario, Canada

Hiram-Walker is a liquor distillery and distributor that uses an ESS to check rivals' performance.
The company collects competitive shipment figures once a month to support company strategic
decisions. Hiram-Walker uses an Information Resources, Inc., product for their ESS application.
• Valspar Corporation, Minneapolis, Minnesota
Valspar implemented Pilot Software's Lightship ESS as a prototype effort to investigate ESS and
quickly build an ESS for one or two top executives. Valspar was looking for a low-cost, Windows
based solution. Valspar is a manufacturer of paints and coatings. They currently use a {Unisys
1100 mainframe and most users access the mainframe via terminals. The Lightship ESS is
operated from a 386-notebook computer. The program shells are setup in Lightship and files are
downloaded onto a floppy every month. Valspar is using Lightship for three applications: profit-
and-loss statements for the corporation and the profit centers, a manufacturing statement for each
of the plants, and a business management report including all the company's divisions.
30.9.2 Medical
• Baylor University Medical Center, Dallas, Texas

The medical center uses Performance Advisor to supplement. its mainframe general-ledger pro-
grams. The product helps create flexible budgets that allow various levels of customer activity.

• Merited Hospital, Madison, Wisconsin

Merited Hospital is using The Alternative View product from Gerber Alley as their £IS for
clinical applications. As part of their total quality management (TQM) process over the last four
years, they have concentrated establishing methods to obtain accurate information from the large
quantity of data processed at the hospital daily.
30.9.3 Government
• Correctional Services Of Canada (CSC)

CSC is one of Canada's largest government departments. In 1990, CSC was facing a serious
information crisis. With responsibility for the care and safe control of more than 21,000
offenders, 10,500 employees, and a one billion dollar budget, executive and managers lacked
the technological resources to transform mountains of transactional data into useful
information to assist the decision-making process and to measure performance. Implementing
an £IS allowed esc to turn their information problem around. The ESS was built around Coe’s
corporate values, especially access to information and management accountability. Also, the
future corporate objectives were considered when developing the ESS.
The system focuses managers and executives on key performance indicators, enhances their
follow through and communication with others, and tracks early warning indicators of
potential problems such as inmate population increases and budget deficits. CSC selected
Comshare Inc's Commander ESS for implementation across ten provinces and two territories.
CSC wanted to implement its new client-server system quickly and selected Commander
because it provided a complete off-the-shelf solution. Using Commander, CSC had the
system up and running in three months.
The ESS is part of CSC's strategic information network (SIN) which includes a host of
communications and office automation applications. SIN 'consists of 41 local area networks
(LANs) and 160 servers linked through a wide-area network (WAN). The £IS provides 288
CSC users access to six custom-designed executive applications that extract information from
separate databases at the local, regional, and national level.
• Naval Computer & Telecommunications Command, US Navy, Washington DC

The Naval Computer and Telecommunications Command consist of 15,000 personnel
performing activities at 30 sites worldwide. Their mission is to provide information,
management capabilities to Navy and joint DOD communication programs. The Command
must keep abreast of all the programs, data requirements, and new information technology.
The commander and 35 executives within the organizations use an internal ESS to track
program progress and the assist in decisions. NCTC is also implementing an £IS in the
operations area for the first time outside the headquarters building. The Greatest present
roadblock is the issue of multilevel security, being able to combine classified and unclassified
data.
30.9.4 Financial
• Great-west Life Assurance Of Winnipeg (Canada)
This company uses preformatted screens in their ESS to display sales figures from the
previous day. They are also using a package from Information Resources, Inc., to prototype a

new system where nationwide sales figures can be monitored. Currently, the information
systems department in Winnipeg prepares the information on a HP UNIX server, then pulls
information from an IBM mainframe, and crunches the numbers for the reports. Data are
distributed overnight to end-users' 386 and 486 DOS-based personal computers. Great-West
Life would like to move to a client-server arrangement, so PC users could access data on the
server, but communication costs are too high.
• Key Bank Of New York, Albany New York

Due to most computer users' comfort with spreadsheet applications, Lotus 1-2-3 was the
natural choice as the key component of the bank's new ESS. Titled; "Vision 2001," this ESS
will completely reengineer the flow of data and will supply executives with a new level of
customer data. The platform for this ESS will be chosen to allow Lotus 1-2-3 to maintain an
important pal\., c III the corporation for the future.
.
30.10 ESS implementation: Success or Failure
The implementation of ESS is different from implementation of DSS or any other computer based
information system since it involves executives. The following factors are critical for successful
implementation of ESS
1. A committed and informed executive sponsor - There must be an executive who has both a
realistic understanding of the capabilities of ESS, and who really wants the system so badly
that he is willing to put considerable time and energy till the system gets developed. He
should also be committed to the company and should have complete knowledge about the
resources of the company.
2. An operating sponsor - As the executive sponsor usually lacks sufficient time to devote to the
project, there should be an operating sponsor designated to manage the details of
implementation from the user's side.
3. A clear link to business objectives - The ESS must help in solving business problems or meet
the needs that are addressed most effectively with information systems technology. It should
also provide very rapid access to external database, best graphical displays and data with
textual annotations
4. Appropriate information system resources - The quality of ESS project manager is very
critical. This person should not only have technical knowledge but also business knowledge
and the ability to communicate effectively with senior management.
5. Appropriate technology - The choice of hardware and software has a major bearing on the
acceptance and rejection of any system. The ESS system when implemented should be in
such a way that it supports vast variety of hardware and software.
6. Management of data problems - The physical and technical ability to provide reliable access
to data can be major issue in ESS development.
7. Management of organizational resistance - Political resistance to ESS is one of the most com-
mon causes of implementation failure of ESS. An ESS alters information flows and this
always has the potential to significantly shift power relationships in a company
8. Prototype Development - A small prototype of the system should be developed, tested and
evaluated before making a new ESS.
30.11 Summary

Executive Support Systems meet the needs of corporate executives by providing them with vast
amounts of information quickly and in graphical form to help them make effective decisions. ESS must
be flexible, easy to use, and contain both internal and external sources of information.

UNIT V
Lesson 31 - Overview on Artificial Intelligence, Neural Networks and Fuzzy Logic
Learning Objectives
1. To know about expert systems and their contribution in organisational decision making
2. To study the support offered by Artificial Intelligence
3. To know more techniques of Expert Systems like Neural Networks and Fuzzy Logic.
31.1 Introduction
Some business problems are straight forward. In these cases, developer simply creates a set of
rules or procedures to follow that a computer can be programmed to follow. As long as the business
behaves in a predictable manner the rules apply and the computer can handle the details. However many
business problems are less structured and can not be solved so easily. Additionally, problems often are
involved data that is not well defined. For example, it is straight forward to create a computer system to
handle inventory because the computer can easily keep track of items numbers and the quantities sold.
Consider the more difficult problem faced by a manager who has to decide where to locate a new plant.
Some attributes are non-measurable such as distance from supplier, cost of land and taxes. Other features
are difficult to quantify: quality of the labor force, attitudes of the government officials and long run
political stability of the area. Many problems involve non-numeric data and complex inter-relationship
among the various factors without computers businesses often call in-experts or hire consultants to solve
these problems. The special software programs called expert systems (ESs) provide many of these
features.
From the beginning researchers and computer designers have known that human can perform
such tasks much better than computers can. These differences led researchers to investigate how people
solve problems and investigate how humans think. The research into techniques that might make
computers “think” more like human as Artificial Intelligence(AI). Let us see this and some other
techniques come out of these efforts in the following sections.
31.2 Artificial Intelligence
Many people have the impression that Artificial Intelligence (AI) is all about computers taking
over the world and turning on their human inventors. That's not true; they can't replace humans. We'll find
out why in this section.
What Is Artificial Intelligence?

FIGURE 14.5
The artificial intelligence family
As you can see from the above figure, the field of AI includes many initiatives. Artificial
intelligence is the art and science of adapting computers to emulate how humans think and act and make
decisions. AI is also used to accomplish physical tasks that may be too dangerous for humans and to use
logic to help humans solve problems. While computers seem smart, they are only as good as the humans
who program them. Most important, they aren't capable of true human behavior. That is, they can be
programmed to perform human-like actions, but they can't truly act like a human.
For instance, much of human behavior is based on intuition; some call it gut reaction. If we sense
that the fire is hot, we jerk our hand away. If we sense we are falling, we grab for something to break our
fall. You could argue that these reactions are learned by having our hand burnt or suffering painful bruises
from previous falls. Computers could eventually "learn" the same behaviors, but the parameters for
reacting would have to be programmed into them by humans.
What also sets humans apart from computers is that we think and act based on concepts. When
you look out the window and see the wind blowing, what goes through your mind and what do you do? It
depends. It depends on whether it's winter or summer. It depends on whether it's raining, snowing, or
neither. If it's winter and snowing, you'll grab an extra heavy coat, your gloves, your boots, and maybe a
scarf. If it's summer with no rain, you may be happy with a nice breeze. Your actions are based on
concepts and impressions. A computer can't act on concepts and impressions. It acts on facts fed to it by a
program.
31.3 Why Business Is Interested in Artificial Intelligence
Businesses are interested in AI because of the characteristics it offers that no other system type
offers. That is, AI's ability to:
• Preserve intelligence and knowledge: Computers don't quit the job on a moment's notice
(they just crash at unexpected times).
• Store information for access by a wider group than may be possible with a human: You can
pass computer information around much easier than you can a person.
• Create a mechanism to supplement humans in dangerous, repetitive, physical situations: You
can use AI systems for building security.
• Eliminate monotonous jobs: Many factories are replacing humans with computers (robots) to
complete boring, repetitious tasks.
• Suggest solutions that were used in similar situations: Yes, the local human expert can advise
you on how the job was accomplished last year, but the computer is accessible to a wider
range of people.

31.4 Capturing Knowledge: Expert Systems
Expert systems are a common form of artificial intelligence. They are used to assist humans in
the decision-making process, but they don't replace humans. Many of the decision we make are based on
past experience, but we have the added benefit of reasoning and intuition. Expert systems ask questions,
then give you advice and reasons why you should take a certain course of action based on hard data, not
on hunches. Again, they don't make the final decision.
Most of the problems an expert system helps resolve can in fact be solved by a human. But since
the computer is faster or safer, businesses choose to use them instead.
How Expert Systems Work
Expert systems rely on a knowledge base built by humans based on their experiences and
knowledge. The base requires rules and knowledge frames in which it can process data. When you think
about it, humans work the same way. You look out the window to see if it's raining. If it is, then you grab
your umbrella. If it's not raining, then you don't. There you have it: a rule base.
Knowledge frames "represent knowledge by organizing information into chunks of interrelated

characteristics." Your knowledge frame would be comprised of the fact that when it rains, you get wet;
therefore you need to prevent that from happening.
Yes, we used a very simplified example. Most expert systems require thousands of rules and
frames in which to operate. The knowledge must be specific. In the example above, you wouldn't take any
action if the only information you had was "It rains 350 days a year in the Amazon rain forest." Neither
would an expert system.
The AI shell (the programming environment of an expert system) uses rules, frames, and an
inference engine to accomplish its tasks. The inference engine uses forward chaining or backward
chaining to move through the rules and the frames.
In our example, using a forward chaining inference engine, you would start with the idea that it's
raining. You'd move through a series of decisions until you reached a conclusion and acted on it. You
would determine that it's raining, then you'd decide how much, then you'd decide how wet you don't want
to be, then you'd decide to take an umbrella. As long as the answer continues to be yes, you keep moving
forward.
In a backward chaining inference engine, you'd start with a hypothesis and work backward until
your hypothesis is proved or disproved. You got wet because it was raining; using an umbrella would
have prevented that from happening.
Building an Expert System
You build an expert system the same way as you build other Information Systems. However, it's
even more important to maintain and update an expert system: You never want to make decisions based
on outdated or incorrect information. A knowledge engineer is especially adept at pulling information
from various sources, including humans, and making sure it fits into the expert system.
Examples of Successful Expert Systems

You measure the success of an expert system by:
• Reduced errors
• Reduced cost, reduced training time
• Improved decisions
• Improved quality and services
• Happy users and happy customers
Most problems solved by expert systems are mundane situations. "If it's raining then take an
umbrella." But what happens if it's cloudy and only looks like it will rain? That's the exception to the rule
about which the human being should make the final decision. The expert system might advise taking the
umbrella along or leaving it home based on the input. The human makes the final decision to take or leave
the umbrella.
Problems with Expert Systems
If you understand that expert systems can only do so much, you'll be just fine. If you understand
that they aren't people with the powers of reasoning and intuition and therefore they can't make every
decision, you'll know when to override the system and when to go with its output. Remember that
everything in an Expert System is based on IF this, THEN that. But we know not everything is black and
white, and there are many gray areas.
Expert systems should not replace managers. They can aid managers in the decision-making
process, but managers have to make the final call. For instance, you suggest to your boss that you should
receive a pay raise. You have many subjective reasons why you should receive the raise; you arrive early
and stay late, your work is always (well almost always) turned in on time, you filled in for Sam while he
was on vacation. What happens if your boss feeds that into an expert system that uses only facts? You
may or may not get the raise. Your boss still needs to use intuition, reasoning, and gut reaction to make
the final decision.
31.5 Organizational Intelligence: Case-Based Reasoning
So far, we've concentrated on capturing the individual knowledge in an expert system. Through
practical experience, you've realized that "two heads are better than one." Very seldom will only one
individual work on a project. Or perhaps one individual works on the candy bar ad campaign while
another works on the breakfast cereal campaign. They have different and yet similar experiences. What if
you could tap into each person's experience and knowledge on a collective basis? Take the best of the best
from each one and apply it to your needs. Then you give your knowledge to someone else who will
combine it with knowledge from others and continuing building on "the best of the best." That's what a
case-based reasoning (CBR) system does best.
The Help files you find in most desktop software applications are built on a case-based reasoning model.
The technical support staff combines thousands of customer queries into a single database of problems
and solutions and refines that information into a series of IF this is the problem, THEN try this. Access
the Help files in your desktop software and try it.

FIGURE 14.9
The above figure gives you an excellent overview of how a case-based reasoning system works.
Businesses are interested in Artificial Intelligence to preserve the experience and knowledge of
their employees and use it to their competitive advantage. Expert Systems emulate humans in the
decision-making process but cannot replicate the intuition and reasoning that still require the human
touch.
31.6 Other Intelligent Techniques
We've said all along that computers can't replace humans. Some systems are coming pretty close,
though.
Neural Networks
This type of Knowledge System is as close to emulating the human ability to learn as we've been
able to come. The text discusses how neurons, along with synapses, work in a brain. That's basically how
neural networks operate.
Let's return to our umbrella example. How do you know to take an umbrella when it's raining?
You probably got wet a few times without one. Then you tried using one when it rained and discovered
that you didn't get wet. You learned that when it rains, an umbrella will keep you dry.

You give a neural network data for which you already know the output so that it has a base of
correct information upon which it can build. When you give it new, different data, the computer will
compare it with the previous data to determine what the correct outcome of the situation should be. If the
data don't fit, it figures out why. It adds that information to its current database of knowledge and then
keeps taking in more data. It eventually learns the right outcome. The more data it takes in, and the more
situations it gets right, the better it becomes at knowing the right answer to the next set of decisions.
The Difference between Neural Networks and Expert Systems
• Expert systems emulate human decision making

• Neural networks learn human thought processes and reasoning patterns
• Expert systems use rules and frames in which to make their decisions
• Neural networks adjust to inputs and outputs
• Expert systems require humans to update their database of information

• Neural networks continue to expand their own base of information
Fuzzy Logic
Okay, one more time, back to our umbrella. If it's only cloudy outside, how do you know whether
to take the umbrella? "It depends on how cloudy it is," you say. If it looks like rain, you know to take the
umbrella; there is a strong possibility that it will pour buckets. If it's only a little cloudy and doesn't look
like rain, you'll take the chance that you won't get wet and leave the umbrella at home. That's fuzzy logic!
Fuzzy logic, a relatively new rule-based advance in AI, is based on approximate values and
ambiguous data. A fuzzy logic system will combine various data into a range of possibilities and then
help solve problems that we couldn't solve before with computers.
Genetic Algorithms
We've evolved as a human race through genetics. We are made up of many combinations of
generations of humans. That's how genetic algorithm systems work. Solutions to problems are examined
by the system. The best solution is retained for future use, while the worst solutions are discarded. The
solutions that are retained are used to help provide better solutions to future problems. They are combined
and mutated the next time they are used.
Businesses often need to solve problems that are dynamic, complex, and have many variables.
Very few problems are clear-cut, black and white. Genetic algorithms are good systems for businesses to
use because it's almost like having millions of people coming at a problem from all directions.
Hybrid AI Systems
We've mentioned before about taking the best of the best and that's just what hybrid AI systems
are. They take the best parts of expert systems and the best parts of fuzzy logic, and the best parts of
neural networks, and combine them into one system that solves the problem. You can look forward to
more of this hybridization as we continue to expand our knowledge of technology and human beings.
Intelligent Agents

Jump on the Web and find the best price for computer printer supplies. Simply typing the words
"computer printer supplies" into your favorite search engine will result in thousands of pages with more
than just price information. You can find specific information on prices much faster using an intelligent
agent. These software programs learn your personal preferences for accomplishing simple tasks and can
take the drudgery out of repetitive, specific work.
Businesses can use intelligent agents to help train users on new systems, schedule appointments,
or monitor work in progress. By far though, the most popular use of this nifty little software program is
that of a "shopping agent" which surfs the Web for you looking for specific items to purchase or the
lowest prices on a particular item.
31.7 Summary
Complex decisions, such as diagnostic problems, require more sophisticated computer tools.
Expert systems can be used to solve complex problems if the problem can be narrowed down to specific
problem. Expert systems ask questions of the users and trace through the rules to make recommendations.
The systems can also trace backward through the rules to explain how they arrived at various questions or
conclusions. Experts systems can be built using shells that contain the logic needed to process the rules.
Research into making machines more intelligent has led to several techniques and tools that can be useful
in solving some problems. Pattern recognition problems are involved in handwriting and voice
recognition, vision systems, and in statistical applications. Researchers are also working on robotics and
motion – especially combined with vision systems that will enable robots to navigate their way through
new areas.

Lesson 32 – Business Process Re-engineering (BPR)
Learning Objectives

4. To study about the restructuring of any organisation by BPR
32.1 Introduction
Organizations are managed today by a set of principles that have evolved since the beginning of the
industrial revolution. This revolution started with the concept of division of labor, conceived by Adam Smith in
1776. According to this concept instead of one craftsman making an entire product (such as a shoe or a pin), several
people would make the product each specializing in one task. Each task would be relatively simple, so it would be
easy to learn. This would reduce the long apprenticeship periods. In addition, when people specialize in these sim-
ple tasks, output can increase. This situation led to cheaper products and higher demand. Since the tasks were
simple, they were easy to automate when machines were introduced. Automation reduced the price of products
further and further, and factories became larger and larger. Instead of producing for customers after an order was
placed, products were produced in large quantities and sold in the market place. Several principles and methods
were created over the years that enhanced the development of the Industrial Revolution. The most important ones
are:
• Specialization of labor
• Mass production (producing large quantities, storing them, selling them at a later time)
• Hierarchical organizational structure following functional specialties with top down lines of authority
• Assembly lines that bring the work to the worker whenever possible
• Complex support systems for planning and budgeting, resource allocation, coordination, and control
These principles and methods were successful in developing world-class organizations, moving nations to a
developed status, and significantly increasing standards of living.
As long as the pace of the changes was slow, it was possible to deal with the changes by using continuous
improvement programs, which included automation of existing processes, small structural modifications, quality
and productivity improvement programs, and modifications in management procedures. However, as the pace and
the magnitude of business pressures and changes accelerate, continuous improvement programs could become
ineffective in many cases. As the saying goes, the old tricks simply do not work.
This lesson introduces you to the topic of reengineering the business, known as business process
reengineering (BPR), and the major role that IT plays as a BPR enabler. First let us begin with a discussion of why
BPR is becoming a major issue in business.
32.2 Definitions
A business process is a collection of activities that take one or more kinds of input and create an output of
value to the customer. For example, accept an application for a loan, processing it, and approving (or rejecting) it is
'"' business process in a bank.
What is a business process?

The following are some examples of business processes:
1. Credit card approval. An applicant submits an application. The application is reviewed first to make
sure that the form has been completed properly. If not, it is returned for completion. The completed
form then is verified by checking a report from a credit company and calling references. Once the
information has been verified, an evaluation is done. Then, a yes or no decision is made. If the decision
is negative, an appropriate rejection letter is composed. If the decision is positive, an account is opened,
and a card is issued and mailed to the customer. The process is usually done by several individuals.
2. Processing an expense form. An employee submits a form for expense reimbursement. The form is
checked for completeness and eligibility is checked. A certain amount is then approved for reimburse-
ment with explanation of any amount denied. An authorization to pay is made, and a check is issued
and sent to the payee.
3. Renewal of a driver's license. The applicant fills out a form and is given a written test of driving rules.
The test is checked. If the applicant passes, he or she takes a vision test. Then a picture is taken, the ap-
propriate fee is collected, and a temporary license is issued. The information is entered into a database
and a permanent license is issued and mailed to the applicant. (In some states a permanent license is is-
sued on the spot.)
4. Manufacturing a toy. A market research is conducted to determine areas of demand. Designers

prepare a prototype for which a marketing test is conducted. If a go decision is made, design improve-
ments are introduced and pricing and advertisement strategies are determined. Production is then
scheduled, materials are purchased and other resources are planned for. The toy is manufactured, tested
and packaged. Shipments to warehouses are made.
An organization operates several business processes designed to attain its goals. For example, a
manufacturing organization includes the following processes: (1) customer ordering, (2) work orders, (3)
manufacturing, (4) distribution, (5) logistics, (6) accounting and finance, and (7) inventory. These processes involve
customers, suppliers, employees, management, and possibly government agencies. Value added is the amount of
value created in each process. The relationship between organizations, major processes, and value added is
summarized in the value chain model.
Business process reengineering (BPR) is the fundamental rethinking and radical redesign of business
processes to achieve dramatic improvements in measures of performance such as quality,' cost, speed, and services.
BPR can be introduced in one, a few or all organizational processes.
• Demand chain. The demand chain describes all the activities that relate to obtaining an order among
all participants: customers, purchasing agents, salespersons, etc. (The chain is a business process that
links organizations with their partners. For example, manufacturers, suppliers, wholesalers, retailers
and customers are all part of the chain.)
• Supply chain. The supply chain describes all the activities that occur once you get an order.
• Extended supply chain. An extended supply chain involves not only the company that produces the
product or the service, but also its suppliers and customers. The process encompasses many activities
starting from order generation to customer service. These activities are intended to add value along the
supply chain. The extended supply chain, which includes both the demand and the supply chain, is
frequently referred to just as the supply chain.

• Supply chain management. The planning, organizing, coordinating, and control of a business process
along the supply chain of a business process is called supply chain management (SCM).
• A networked organization is a combination of entities connected by a computer network.
• Organization transformation is the process of moving from the traditional to a reengineered,
frequently networked, organization.
32.3 When is Business Process Reengineering Needed?
The major environmental pressures are summarized as the three Cs-customers, competition, and change.
• Customers today know what they want, what they are willing to pay, and how to get products
and services on their own terms.
• Competition is continuously increasing with respect to price, quality, selection, service, and
promptness of delivery. Removal of trade barriers, increased international cooperation, and the creation
of technological innovations cause competition to intensify.
• Change continues to occur. Markets, products, services, technology, the business environment, and
people keep changing, frequently in an unpredictable and significant manner.
Since the old methods are not always working, organizations face situations like the one described in the
following example.
Nick Simmons had accepted an executive position with Honeywell in Minneapolis; he contacted his
insurance company in his home city, Detroit. He had been a C1 tamer for the past 25 years and wanted to transfer
his insurance to the Minneapolis office keeping the same life, health, personal liability, and auto coverage.
Much to Nick's disappointment, he found that he would have to contact an age when he arrived in
Minneapolis and reapply for insurance. Nick asked his agent in Detroit whether she could at least give him the
name of a good agent in Minneapolis. He was to the best thing to do would be to look up an agent in the Yellow
Pages. Nick had been loyal for over 25 years and was trying to remain a customer. Yet, it was as if the insurance
company was deliberately trying to alienate him.
When he arrived in Minneapolis Nick checked competitive rates on the Intern and found several quotes for
low rates. After making an evaluation, he ended up selecting a new insurance company.
For Further Exploration: Assume that Nick's problem resulted from poor communication and
information flow in the Detroit office of his insurance company, and it lack of access to the data stored in Detroit
from the Minneapolis office. How could the incident have been avoided? Assuming an insurance company is
concerned about retaining customer. The above IT at Work illustrates an organization that is probably not
accomplishing its objectives very well. Research shows that it is five to six times more difficult and expensive to
obtain a new customer than it is to retain an existing client. Yet during the 1980s and early 1990s, customers in
almost every area of business became disillusioned with the types of services they were receiving from mm
organizations. What went wrong with these organizations What needs to be done to correct the problem?
• Techniques lag behind technology. One of today's fundamental organizational problems is that the
ways we do things do not keep up with technology. This has almost always been true. Many of the
approaches that are being used by organizations today were developed before computing technology
and, more recently, network technology. During the Industrial Revolution, the notions of specializing
and "dividing and conquering" were prevalent as organizations developed what is now called the
hierarchical organization or pyramidal structure where the ultimate authority and responsibility reside
at the top. Authority and responsibility flow down through ever-widening successions of levels to the
bottom of the organization.

• Fragmented piecemeal systems: Earlier we mentioned that a problem may arise because of improper
organizational structures and unsuited information systems. For example, a budgeting system was
perceived to be primarily that of the finance department, even though all functional areas of the
organization do budgeting.
• Integration: Besides creating inefficient redundancies, the independent subsystem structure causes
difficulties in the integration of information that is required for decision making purposes. The systems
and files have been developed along department or functional boundaries. For example, account
numbers are not logically related and cannot be used for cross-referencing a customer's accounts. This
seriously limits reporting capabilities. A loan officer, for instance, may want to check information
pertaining to a loan applicant's savings accounts. However, there is no linkage to these data from the
loan system. Indeed, the loan officer may have to ask the loan applicant if he or she has a savings
account with the bank and what his or her account number is.
Consider a case where the management of the bank wants to increase the offering of mortgage loans to
utilize large savings deposits. Management decides to send letters encouraging specific customers to
consider buying homes, using convenient financing available through the bank. Management also
decides that the best customers to which to send such letters are the following:
1. Customers who do not currently have mortgage loans or who have loans for a very small
percentage of the value of their homes.
2. Customers who have good checking account records (Le., few or no over-drafts) .
3. Customers with sufficient funds in their savings accounts to make a down payment on a home.
4. Customers who have good payment records on any installment loans with the bank.
Because the data necessary to identify such customers may be available in different files of different
information systems, there may be no convenient or economic way to integrate them. Using
innovations such as data warehouses and special integrated software can be helpful but expensive.
Therefore, extensive programming and clerical work are required to satisfy such an information re-
quest. Management is understandably disappointed and unable to function effectively. The scenario of
the bank can be translated into other' organizational settings.
32.4 The Principles of BPR and the Role of IT
What is the difference between reengineering and incremental improvement programs? Reengineering is a
part of process innovation, which involves stepping back from a process to inquire into its overall business
objectives, and then effecting creative and radical change to realize order-of-magnitude improvements in the way
that the objectives are accomplished. The term process innovation encompasses the envisioning of new work
strategies, the actual process design activity, and the implementation of the change in all its complex technological,
human, and organizational dimensions.
The differences between process innovation and incremental improvement are shown below
Process Innovation Incremental Improvement

Change Abrupt, volatile Gradual, constant
Effects Immediate, dramatic Long-term, more subtle
Involvement A few champions From few to everybody
Investment High initially, less later Low initially, high to sustain
Orientation Technology People
Focus Profits Process
Characteristics of Business Process Reengineering

The major characteristics are:
1. Several jobs are combined into one.

2. Employees make decisions (empowerment of employees). Decision making becomes part of the job.
3. Steps in the business process are performed in a natural order, and several jobs get done
simultaneously.
4. Processes may have multiple versions. This enables the economies of scale that result from mass
production, yet allows customization of products and services.
5. Work is performed where it makes the most sense, including at the customers' or suppliers' sites. Thus,
work is shifted, if necessary, across organizational and even international boundaries.
6. Controls and checks and other non-value-added work are minimized.
7. Reconciliation is minimized by cutting back the number of external contact Points and by creating
business alliances.
8. A hybrid centralized/decentralized operation is used.
9. A single point of contact is provided to customers, called a "case manager" or a deal structure (see the
following IT at Work).
IBM Credit Corporation Reduced Cycle Time by 90 Percent
IBM Credit Corporation provides credit to customers who purchase IBM computers. The process of credit
approval used to take an average of seven days. Because of the long processing time, salespeople felt that they were
losing many potential customers; therefore, reducing processing time became critical.
The Old Process
STEP 1: The IBM salesperson telephones in, requesting credit approval for a customer.
STEP 2: A clerk logs the call on paper; a messenger takes it to the credit department.
STEP 3: A specialist enters the data into the computer, checks creditworthiness of the potential customer,
and prepares a report.
STEP 4: The report is physically moved to the business practices department.
STEP 5: The business practices department modifies a standard loan to fit the customer's needs.
STEP 6: Using a spreadsheet, a pricer determines the appropriate interest rate and payment schedule.
Another piece of paper is added to the application.
STEP 7: An administrator uses the information to develop a quote letter.
STEP 8: The quote letter is delivered to the salesperson, who submits it to the customer.
Incremental attempts to increase productivity improved some of the activities, but the overall time
reduction was minimal.
The Reengineered Process

One person, called a deal structurer, conducts all the above steps. One generalist replaces four specialists.
To enable one person to execute the above steps, a simple DSS provides the deal structurer with the guidance
needed. The program guides the generalist in finding information in the databases, plugging numbers into an
evaluation model, and pulling standardized clauses-"boilerplate" -from a file. For difficult situations, the generalist
can get help from a specialist.
Results
The turnaround time has been slashed from seven days to four hours! Furthermore, IBM credit can handle
a volume of business up to 100 times larger now.

Role of IT
The role played by Information Technology for any process innovation and subsequent Reengineering can
be listed down as follows:
1. IT supports changes in the organization structure.

2. IT supports changes in the business process.
3. IT supports shortening the time-to-market.
4. IT supports customer-centered organizations.
5. IT enhances empowerment of employees.
6. IT enhances TQM programs.
The role of IT can be very critical and it is increasing due to the Internet/intranet. Geoffrey (1996) provides
several examples of how intranets have rescued BPR projects. One of these, the AT&T case, is described next.
32.4 BPR and Restructuring the Organization
Reengineering efforts involve many activities, four of which are described in this section: redesign of
processes, mass customization, cycle time reduction, and restructuring the organization. Several other activities are
described in the forthcoming sections.
a. Redesign of Processes: One of the most publicized examples of redesign is the accounts payable process at Ford
Motor Company. The example is illustrated below.
As part of its productivity improvement efforts, Ford management put its North American Accounts
Payable Department under the microscope in search of ways to cut costs. Management thought that by streamlining
processes and installing new computer systems, it could reduce the head count by some 20 percent to 400 people.
But after visiting Mazda's payables department (Ford is part owner of Mazda), Ford managers increased
their goal: perform accounts payable with only 100 clerks. Analysis of the existing system revealed that when the
purchasing department wrote a purchase order, it sent a copy to accounts payable. Later. When material control
received the goods, it sent a copy of the receiving document to accounts payable. Meanwhile, the vendor also sent
an invoice to accounts payable. If the purchase order, receiving document, and invoice matched, then the accounts
payable department issued a payment. Unfortunately the department spent most of its time on the many
mismatches. To prevent them, Ford instituted "invoiceless processing." Now, when the purchasing department
initiates ax order, it enters the information into an online database. It does not send a copy of the purchase order to
anyone. The vendor receives notification through an EDI.
When the goods arrive at the receiving dock, the receiving clerk checks the database to see whether the
goods correspond to an outstanding purchase order. If so, he or she accepts them and enters the transaction into the
computer system. (If there is no database entry for the received goods, or if there is a mismatch, the clerk returns
the goods.) .
Under the old procedures, the accounting department had to match 14 data items among the receipt record,
the purchase order, and the invoice before it could issue payment to the vendor. The new approach requires
matching only four items-part number amount, unit of measure, and supplier code-between the purchase order and
the receipt record. The matching is done automatically, and the computer prepares the check, wlIi4 accounts
payable sends to the vendor (or an electronic transfer is done). There are no invoices to worry about since Ford has
asked its vendors not to send them. The reengineered system as compared to the old one is shown in the figure
below. .

Ford did not settle for the modest increases it first envisioned. It opted for a radical change and it achieved
dramatic improvement: a 75 percent reduction in head count, not the 20 percent it would have achieved with a
conventional improvement program. And since there are no discrepancies between the financial record and physical
record, material control is simpler, receipts are more likely to be correct, and financial information is more accurate.
b. From Mass Production to Mass Customization
One of the most innovative concepts of the Industrial Revolution was mass production. In mass production,
a company produces a large quantity of an identical, standard product. The product is then stored for future
distribution to many customers. Because the concept of mass production results in a low cost, products are
relatively inexpensive and sold in department or specialty stores to unknown customers. The concept of mass
production was adapted to thousands of products, ranging from simple watches to major appliances, vehicles, and
computers.
A major change in marketing started about 30 years ago with the increased competition between
automobile manufacturers. Customers were able to select "options," such as an air conditioner or automatic
transmission. Manufacturers collected the customized orders. Once they accumulated enough similar orders to
justify manufacturing the customized product, they produced the items. The result was a waiting time of several
months. A similar strategy was developed in other relatively expensive products. However, today's customers are
not willing to wait so long (see the Volvo case in Chapter 3, Section 3.6). The solution was found in mass
customization.
The concept of mass customization may be essential to the survival of many companies as we enter the
twenty-first century. The basic idea is to enable a company to produce large volumes, yet to customize the product
to the specifications of individual customers. Mass customization enables a company to provide flexible and quick
responsiveness to a customer's needs, at a low cost and with high quality. It is made possible by allowing fast and
inexpensive production changes, by reducing the ordering and sales process, by shortening the production time, and
by using prefabricated parts and modules as shown in the following IT at Work example.
Bally Engineered Structures of Bally, Pennsylvania, was established in 1933 as a producer of custom-made,
insulated products for commercial and industrial uses. When the market matured in the 1970s, Bally found itself
competing in a price-sensitive market. and the company developed into a mass production operation in order to
reduce cost. However, with the beginning of the 1990s, the competition shifted from an emphasis on price alone to
price-and-customized products. Bally (which employs 400 people) established new goals. They included: (to)
customizing of products to suit the needs of the individual customers, (2) continuously developing new products,
(3) delivering products to customers faster than the competition, and (4) reducing the overall manufacturing and
administrative costs. These goals required a massive reengineering of the manufacturing process and other
company processes.
First Bally introduced a computer-driven intelligent system to reengineer sales and ordering processes,
which were composed of 86 sequential tasks which could take five to seven weeks. A redesign of the sales and
order entry system allowed salespeople to access information directly from a minicomputer via their own personal
computers. Salespeople are able to provide customer requirements, receive price quotations, identify order status
and shipment information, receive specification drawings, and communicate with anyone in the company through
the electronic mail system. As a result, the sales and ordering process was reduced to less than 20 tasks and took
only one to two weeks.
Another improvement of the computerized system was the direct input of customer configurations into a
CAD system. From the initial design, bills of materials were generated and copies could be sent via fax machine
(now Internet fax) directly to the customer. This also allowed the elimination of a complex system of checking and

comparing the components. Every employee has access to all data needed for his or her job, and unnecessary
paperwork has been minimized. As a result, the number of customer options has soared from 12 to 10,000, making
Bally a true mass customizer. Bally also developed a computerized network that links sales representatives,
customers, production people, and suppliers into one system which shares information across the entire supply
chain. This system evolved by 1998 into an Internet community (see Chapter 7).
Without mass customization, Bally would be a struggling company fighting to cut prices with other
competitors. Today, however, the company has a leading position, with 12 to 15 percent of the $500 million U.S.
market.
c. Cycle Time Reduction
Cycle time refers to the time it takes to complete a process from beginning to end. As discussed earlier,
competition today focuses not only on cost and quality but also on time. Time is recognized as a major element that
provides completive advantage, and cycle time reduction is a major business objective.
The success of Federal Express, for example, is clearly attributable to its ability to reduce the delivery time
of packages with complex computer-supported systems that allow flexible planning, organization, and control. The
comeback of Chrysler Corporation and its success in the 1990s can attributed largely to its "technology center,"
which has brought about a more than 30 percent reduction in its time to market (the time from beginning the de.
sign of a new model to the delivery of the car). Boeings corporation reengineered its design of airplanes by moving
to total computerization. The first airplane designed in this manner was the 777. In a fundamental change to
Boeings processes, a physical prototype was never built. In addition to reducing the cycle quality has been
improved and costs reduced. Because of this, Boeing was able to compete successfully with Airbus Industries.
Notice that both in Boeings and Chrysler's cases the change was fundamental and dramatic. First, the role 0 the
computer was changed from a tool to a platform for the total design. Second it was not just a process change, but a
cultural change relative to the role of the purer and the design engineers. According to Callon (1996), the engineers
are now a part of a computer-based design system. Computing also played major communications role during the
entire design process.
There is an old saying that "time is money," so saving time saves money but cycle time reduction does
more than save money. If you beat your computers with a new product, a product improvement, or a new service,
you can gain a substantial market share. Pharmaceutical companies, for example, are deeper artily trying to reduce
the cycle time of new drugs. If successful, they will be the first on the market, they may receive a patent on the
innovation, and revamp will begin flowing sooner to repay their huge investments.
Finally, telecommunications and especially the Internal and intranets provide a means of economically
reducing- cycle time by cutting communications time through the use of e-mail and EDI and by allowing
collaboration in design and operations of products and services.
Cycle time reduction can be very beneficial, but to obtain maximum result from reengineering efforts, it
may be necessary to restructure not just one or few processes, but the entire organization, as we describe next.
d. Restructuring Organizations
We've seen that one problem in many current organizations is vertical structures. How should a
contemporary organization be organized? Answers con from two directions. First, management theories advocate a
structure that pr vides leadership and support for critical activities and strategies. For example cost reduction can be
achieved when some layers of middle management a eliminated. Second, we can examine the relationships between
organization and information systems.
e. Reengineering the Organization. The fundamental problem with the hierarchical approach is that any time a
decision needs to be made; it must climb up and down the hierarchy. All it takes is one person who does not

understand the issues to say "no," and everything comes to a screeching halt. Also, if information is required from
several "functions," getting all the right information coordinated can be a time-consuming and frustrating process
for employees and customers alike.
So, how is reengineering done? It all depends. For example, providing each customer with a single point of
contact can solve the fundamental problem just described. The customer deals with a single point of contact, the
account manager. The account manager is responsible for all bank services, and provides all services to the
customer, who receives a single statement for all his accounts. Notice the role of IT is to back up the account
manager by providing her with expert advice on specialized topics, such as loans. Also, by allowing easy access to
the different databases, the account manager can answer queries, plan, and organize the work with customers.
32.5 Virtual Corporations
One of the most interesting reengineered organizational structures is the virtual organization, usually
referred to as a virtual corporation (VC). The creation, operation, and management of a VC is heavily dependent on
IT and is especially facilitated by the Internet and electronic commerce.
A virtual corporation is an organization composed of several business partners sharing costs and resources
for the purpose of producing a product or service. The virtual corporation can be temporary, with a onetime mission
such as launching a satellite, or it can be permanent. Each partner contributes complementary resources that reflect
its strengths, and determine its role in the virtual corporation. Virtual corporations (VCs) are not necessarily
organized along the supply chain. For example, a business partnership may include several partners, each creating a
portion of a product or service, in an area in which they have special advantage such as expertise or low cost.
Permanent virtual corporations are designed to do the following:
• Create or assemble productive resources rapidly.

• Create or assemble productive resources frequently and concurrently.
• Create or assemble a broad range of productive resources.
The concept of virtual corporations is not new, but recent developments in IT allow new implementations
that exploit its capabilities (see O'Leary, et a1. [1997]). the modern virtual corporation can be viewed as a network
of creative people, resources, and ideas connected via online services and/or the Internet, who band together to
produce products or services.
The major attributes of virtual corporations are:
• Excellence. Each partner brings its core competence so an all-star winning team is created. No single
company can match what the virtual corporation can achieve.
• Utilization. Resources of the business partners are frequently underutilized, or utilized in a merely
satisfactory manner. In the virtual corporation, resources can be put to use more profitably, thus
providing a competitive advantage.
• Opportunism. The partnership is opportunistic. A virtual corporation is organized to meet a market
opportunity.
• Lack of borders. It is difficult to identify the boundaries of a virtual corporation; it redefines
traditional boundaries. For example, more cooperation among competitors, suppliers, and customers
makes it difficult to determine where one company ends and another begins in the virtual corporation
partnership.
• Trust. Business partners in a VC must be far more reliant on each other and require more trust than
ever before. They share a sense of destiny.

• Adaptability to change. The virtual corporation can adapt quickly to the environmental changes
discussed in Chapter I because its structure is relatively simple.
• Technology. Information technology makes the virtual corporation possible. A networked information
system is a must.
32.6 Implementing Reengineering
We have defined reengineering as achieving dramatic performance improvements through radical change
in organizational processes. This really means creating new architecture for business and management processes. It
involves the redrawing of organizational boundaries, the reconsideration of jobs, tasks, and skills. It literally means
"rethinking everything." It is also important to understand what reengineering is not. Reengineering is not across-
the-board cuts in employees or blind head count reduction, and, it is not "automating the history."
There are several methodologies for executing BPR. These methodologies include many activities. The key
activities of reengineering can be organized into three phases referred to as the 3 R's of Reengineering, which
includes redesign, retool, and reorchestrate.
• Redesign: The redesign of an organization must, first of all, have an ambitious, .cross-functional scope. It
is not about improving a department or a function; it is about improving cross-functional activities.
Typically, an organization that tries to cut costs by 5 to 10 percent often compromises services. However,
organizations that try to cut costs by 50 percent often end up improving service. Why? Because you can
save 5 to 10 percent by compromising customer service. But a 50 percent cut will require an entirely new
process.
• Retool: To retool for reengineering, the key issue is getting a good understanding of the current installed
base of information systems applications and databases (see Rose [1995]). It is also important to understand
the existing infrastructure in terms of computing equipment, networks, and the like, and their relationships
to the current available software, procedures, and data. The key is an assessment of what the ideal IT
architecture would be for the organization in terms of hardware and software, as well as appropriate
information architecture.
During this stage, it is very important to benchmark the technology being used in the organization against
what the best competitors are using. It is also imperative to find out what the latest technologies are and
determine in what direction the organization needs to go.
• Reorchestrate: The tools employed in various levels have to organised and co-ordinated in an effective
manner top ensure the proper implementation. Normally companies will set standards for ensuring the
smoother application and organisation of tools throughout the various processes in reengineering.
32.7 An Integrated Example in BPR
DELL REENGINEERED THE PC MANUFACTURING SYSTEM
The Problem
MICHAEL DELL STARTED his business as a student, from his university dorm, by using a mail-order
approach to selling PCs. This changed the manner by which PCs were sold. First, the customer did not have to
come to a store to buy the computer, and second, Dell was able to customize the computer to the specifications of
the customer, economically and in a very short time. The direct mail approach enabled Dell to under price its rivals,
who were using distributors and retailers, by 10 percent. For several years the business grew slowly but Dell
constantly captured market share. In 1993, Compaq, at that time the PC market leader, decided to cut prices to drive
Dell out of the market. As a result of the price war, Dell Computers Ine. had a $65 million loss from inventory write
downs in the first six months of 1993. The company was on the verge of bankruptcy.

The Solution
Dell realized that the only way to win the price war was to introduce fundamental change in its own busi-
ness, namely to reengineer it. In addition to competing on price and quality Dell started competing on speed. In
1998, if you ordered a standard PC on Monday, the computer was on the delivery truck the next day; a complex
custom-made PC is delivered in 5 days or less.
Among the innovations used to achieve this speed, many of which are IT-supported, were:
• Dell builds many computers only after they are ordered. This is done by using just-in-time manu-
facturing, which also enables quick deliveries at low cost.
• Using an approach called mass customization, meaning producing large quantities of customized
products, at a low cost.
• Placing its component warehouses, which are maintained by its suppliers, within 15 minutes of Dell
factories? Not only can you get parts quickly, but also you get parts that are up to 60 days newer than
those of the major competitors.
• Shipments, which are done by UPS and other carriers, are all arranged by electronic mail.
• Dell collaborates electronically with its major buyers to pick customers' brains.
• Most of Dell's customers are large corporations. While individual buyers want their units customized,
large corporations may prefer standard computers. For example, Eastman Chemical Company needed
10,000 PCs, all with exactly the same parts and software, regardless of when and where in the world
they were needed. The standardization saved operation and training maintenance costs of about $5
million annually for Eastman. Dell was the only vendor that was able to fulfill this need.
• Dell's new PC models are tested at the same time as the networks that they are on are tested. This coop-
eration with another vendor reduced the testing period from 60 to 90 days to 15.
• Dell employees are constantly monitoring productivity and rate of return on investments.
And What Role Did Information Technology Play?
Most significant is the emergence of electronic commerce. In 1998, Dell was selling more than $1.5 million
worth of computers each day on its Web site, and this amount was growing 20 percent per month! As a matter of
fact Dell is aiming to sell most of their computers on the Web (www.dell.com). Customers can create their own
Dell home page and track their orders online, to see if they are in production, or already on the shipping track.
Customers can access detailed diagrams of the computers and get information about troubleshooting. By view-
approved configurations and pricing and by eliminating paperwork customers were able to save 15 percent of
administrative process expenses. In addition, Dell created home pages for their biggest buyers, such as Eastman
Chemical, Monsanto, and Wells Fargo. These sites enable their customers' employees to place orders quickly and
easily. These employees can also order PCs for their homes and receive the corporate price! The electronic ordering
makes customers happy, but it also enables Dell to collect payments very quickly.
Dell is using several other information technologies including e-mail, EDI, video teleconferencing, computerized
faxes, an intranet, DSS, and more. Of special interest is a computerized manufacturing system introduced in 1997,
which tightly links the entire demand and supply chains from suppliers to buyers. This system is the foundation on
which the "building-to-order" strategy rests.
Four years after its "almost" collapse, Dell became an unbelievable success story when its stock price zoomed more
than 2000 percent in about two years. Competing with world-class names such as IBM, Compaq, HP, and Packard
Bell-NEC, Dell consistently increased its market share and profitability simultaneously.
The Results

By the late 1990s Dell was considered to be one of the best managed and profitable corporations in the
world, as a result of its IT-based reengineering.
The Dell example demonstrates the following points:
1. Competition can be very intense, involving very large corporations.

2. Providing quality products at low prices is necessary, but may not be sufficient.
3. A fundamental change in the manner in which business is done is sometimes
4. The only way to succeed, or even to survive.
Some major features of reengineering include: reducing cycle time, manufacturing to order in an approach
called mass customization, closely managing the entire demand and supply chains from suppliers to buyers,
collaborating with other vendors, and providing unique services to customers

UNIT VI
Lesson 33 - Information Systems Security and Control
33.1 Introduction
There is a little doubt that business use of computers is increasing – to the point where e-
commerce business require all of the compnents to be functioning 24 hours a day.. in this environmemnt
nmanagers need to know what threats they face and what technologies exist to protect the system.there
are three aspects that affect all busineses but are particulary important in e-commerce: 1. intercepion of
transamissions, 2. attacks on servers, and 3. monitoring ystems to identify attacks.
Many potential threats exist to information systems and the data they hold. The complicated
aspect is that the biggest information threat is from the legitimaste users and developers. Purely by
accident, a user might enter incorrect data or delete important information. A designer must understand an
important function and the system will provide erroneous results. An innocent programming mistake
could result in incorrect or destroyed data. Minor changes to a frail system could result in a cascading
failure of the entire system.
We can detect and prevent some of these problems through careful design, testing, training and
backup provisions. However, modern information systems are extremely complex. We cannot guarantee
they will work correctly all of the time. Plus, the world poses physical threats that cannot be avoided:
hurricanes, earthquakes, floods and so on. Often, the best we can do is buid contingency plans that enable
the company to recover as fast as possible. The most imoportant aspect of any disaster plan is to maintain
adequate backup compies. With careful planning, organisation, and enough money, firms are able to
provide virtually continous information systems support.
33.2 System Vulnerability and Abuse
As our society and the world itself come to depend on computers and information systems more
and more, systems must become more reliable. The systems must also be more secure when processing
transactions and maintaining data. These two issues, which we address in this lesson the biggest issues
facing those wanting to do business on or expand their operations to the Internet. The threats are real, but
so are the solutions.
Threats to Computerised Information Systems
• Hardware failure
• Fire
• Software failure
• Electrical problem
• Personnel actions
• User errors
• Terminal access penetration
• Program changes
• Theft of data, services, equipment
• Telecommunications problems
TABLE 16.1
The above list points out some of the technical, organizational, and environmental threats to
Information Systems. The weakest link in the chain is poor management of the system. If managers at all

levels do not make security and reliability their number one priority, then the threats to an Information
Systems can easily become real.
With distributed computing used extensively in network systems, you have more points of entry,
which can make attacking the system easy. The more people you have using the system, the more
potential for fraud and abuse of the information maintained in that system. Yes, it's hard to control
everyone's actions. That is why you have to make it everybody's business to protect the system. It is easy
for people to say that they are only one person and therefore they will not make much difference.
Nevertheless, it only takes one person to disable a system or destroy data. Let us see why.
Hackers, those who intentionally create havoc or do damage to a computer system, have been
around for a long time. Many companies don't report hackers attempts to enter their systems because they
don't want people to realize their systems are vulnerable. That makes gathering real statistics about
hacking attempts and successes hard. It is a huge problem, though.
Some hackers penetrate systems just to see if they can. They use special computer systems that
continually check for password files that can be copied. Or they look for areas of the system that have
been "left open," so to speak, which they can use to enter the system. Sometimes they don't do any
damage, but far too often they destroy files, erase data, or steal data for their own use. Other hackers
attack systems because they don't like the company.
Password theft is the easiest way for hackers to gain access to a system. No, they don't come into
your office at night and look at the piece of paper in your desk drawer that has your password written on
it. They generally use specially written software programs that can build various passwords to see if any
of them will work. That's why you should use odd combinations of letters and numbers not easily
associated with your name to create your password. The longer the password, the harder it is to replicate.
Have you ever picked up a cold or the flu from another human? Probably. You then spread it to
two or three other people through touch or association. Those people spread it to two or three more people
each. Pretty soon it seems that everyone on campus or at work is sick. That is how computer viruses are
spread. You copy a file from an infected source, use the file, and maybe send it to friends or associates.
The virus is now on your computer and spreads to files other than the original. You then send the same or
even a different file to a few friends and their computers are infected.
In March 1999 a virus called Melissa was written by a hacker and sent out via an email
attachment. While the virus didn't damage any computer files or data, it severely hampered normal
operations of many companies and Internet Service Providers through the increased number of emails it
generated. Here's what CERT (Computer Emergency Response Team) said about it: "Melissa was
different from other macro viruses because of the speed at which it spread. The first confirmed reports of
Melissa were received on Friday, March 26, 1999. By Monday, March 29, it had reached more than
100,000 computers. Some sites had to take their mail systems off-line. One site reported receiving 32,000
copies of mail messages containing Melissa on their systems within 45 minutes."
Whether you use a stand-alone PC or your computer is attached to a network, you're just asking
for trouble if you don't have antivirus software. This type of software checks every incoming file for
viruses. Not if, but when, you receive an infected file, the software alerts you to its presence. You can
choose to delete the file or "clean" it. Make sure you update your antivirus software every 30 to 60 days
because new viruses are constantly being written and passed around.
Concerns for System Builders and Users

Every user must be concerned about potential destruction of the Information Systems on which
they rely. We can't stress this point enough. Let us look at three concerns: disasters, security, and errors.
Natural disasters such as fires and earthquakes can strike at any time. A spilled cup of coffee can
also do some damage!
As the lesson points out, many companies create fault-tolerant systems that are used as back-ups
to help keep operations running if the main system should go out. These back-up systems add to the
overall cost of the system, but think about the losses if the company's system goes down. Add the cost of
lost productivity by the employees to the lost transactions and unhappy customers; you do the math.
Just imagine what would happen if an airline reservation system (a typical online transaction
processing system) went down. Have you ever called a company to place an order for a new dress and it
couldn't take your order because the computer was down? Maybe you called back later and maybe you
didn't.
Companies spend a lot of money on physical security such as locks on doors or fences around
supply depots. They need to do the same thing on their Information Systems. Here the security is in the
policies, procedures, and technical measures the company uses to keep out unauthorized users or prevent
physical damage to the hardware.
Surely you've heard the saying, "Garbage In, Garbage Out." What may seem like a simple error to
you may not be to the customer. Let's flip that around; what if you wanted to fly to Dallas on March 15
and the reservation clerk booked you on a flight for April 15? The potential for error exists all through the
processing cycle. You must be cognizant of these error points when designing and building a system,
especially an end-user developed system.
System Quality Problems: Software and Data
It would be nice to have a perfect world, but we donÕt. Defects in software and data are real. You
as an end user can't do much about the software, but you can do something about the data you input.
Bugs and Defects
The term bug, used to describe a defect in a software program, has been around since the 1940s
and 1950s. Back then, computers were powered by vacuum tubes - hundreds and thousands of them.
Grace Hopper, an early pioneer, was troubleshooting a computer that had quit running. When her team
opened the back of the computer to see what was wrong, they found a moth had landed on one of the
tubes and burned it out. So the term "bug" came to describe problems with computers and software.
With millions of lines of code, it's impossible to have a completely error-free program. Most
software manufacturers know their products contain bugs when they release them to the marketplace.
They provide free updates and fixes on their Web sites. That's why its a good idea not to buy the original
version of a new software program but to wait until some of the major bugs have been found by others
and fixed by the company.
Because bugs are so easy to create, most unintentionally, you can reduce the number of them in
your programs by using the tools discussed in other chapters to design good programs from the beginning.
Many bugs originate in poorly defined and designed programs and just keep infiltrating all parts of the
program.

The Maintenance Nightmare
You simply can't build a system and then ignore it. It needs constant and continual attention. The
fact is that half of a company's technology staff time is devoted to maintenance.
When you're considering organizational changes, no matter how minor they may seem, you must
consider what changes need to be made to the systems that support the business unit. Keep in mind that
software is very complex nowadays. You just might have to search through thousands or millions of lines
of code to find one small error that can cause major disruptions to the smooth functioning of the system.
In the SDLC lesson, we stress good system analysis and design. How well you did back then will
play out in the maintenance of the system. If you did a good job, maintenance will be reduced. If you did
a poor job analyzing and designing the system, maintenance will be a far more difficult task.
Data Quality Problems
Let's bring the problem of poor data quality closer to home. What if the person updating your
college records fails to record your grade correctly for this course and gives you a D instead of a B or an
A? What if your completion of this course isn't even recorded? Think of the time and difficulty you'll
experience getting the data corrected.
Information Systems security is everyone's business. Use antivirus software on your computer and update
it every 30-60 days. The "it won't happen to me" attitude is trouble. Many system quality problems can be
solved by instituting measures to decrease the bugs and defects in software and data entry.
33.3 Creating a Control Environment
How do you help prevent some of the problems we've discussed? One of the best ways is to
introduce controls into your Information System the same as you might in any other system: through
methods, policies, and procedures.
Think about what a typical company does when it builds a new office building. From the
beginning of the design phase until the building is occupied, the company decides how the physical
security of the building and its occupants will be handled. It builds locks into the doors, maybe even
designs a single entry control point. It builds a special wing for the executive offices that has extra-thick
bulletproof glass. Fences around the perimeter of the building control the loading docks.
These are just a few examples to get you to think about the fact that the company designs the
security into the building from the beginning. You should do the same thing with an Information System.
It's no different from any system that requires preplanning and well-thought-out policies and procedures
before the building begins.
Let's look at the two distinct types of controls: general controls, which focus on the design,
security and use of computer programs and data files, and application controls, which are concerned
with the actual application programs.
33.3.1 General Controls

General Controls in Information Systems consist of the systems software and manual procedures
used to control the design, security, and use of the programs and the data files in the overall system.
General controls would be the overall security system, which may consist of outside door locks, fencing
around the building, and employee passes. General controls wouldn't be concerned with what happens in
one particular area of the building.
• Implementation Controls: When you use implementation control methods, you audit the
development procedures and processes to make sure they conform to the business's standards and
policies. Were all the steps completed, or did you skip some of them? What input did users and
management have in the design and implementation of the system? Were managers allowed to
sign off on milestones during the development process, or were they left out of the loop
altogether? There is a reason why you have to use good, sound development procedures.
• Software and Hardware Controls: How is your system software installed, maintained, and
used? What security measures are in place to ensure only authorized users are allowed access to
your system? Are you using the latest version of virus protection software? These concerns are
part of the software controls you should develop.
Companies control all of their manufacturing equipment, office supplies, and production tools--or
at least try to. They should apply the same hardware controls to computer equipment as they
would any other piece of equipment. Sometimes they don't. Laptop computers are especially
vulnerable to theft and abuse: Companies seem to be very lax about employees borrowing laptops
and then never returning them.
• Computer Operations and Data Security Controls: Computer operations controls are the
responsibility of the Information Technology Department staff and are concerned with the storage
and processing of data. Often overlooked in this area is the need for protecting the system
documentation that details how jobs are processed, how data are stored, and how the systems
operate. Someone who steals this information could do serious damage.
Whether you're working with current data or archived data, you still need to protect them from
unauthorized access or use. The movie "The Net" depicted a fictionalized version of data theft
and manipulation. While it may have been an exaggeration, this could happen if a company
doesn't do enough to protect its data.
• Data security controls should consist of passwords that allow only certain people access to the
system or to certain areas of the system. While you may want to grant employees access to their
payroll data or 401K data through an Intranet, you must make sure they can access only their
information and not that of any other employee. You wouldn't want a co-worker to be able to
access your paycheck information, would you?
An effective way of limiting access to data is to establish computer-generated logs that show
every employee who logged on, what he or she did, what part of the system was accessed, and
whether any data were used or updated. Logs are easily created by system software programs and
should be periodically reviewed by the Information Technology staff and department managers.
If nothing else, it gives them an idea of what their employees are doing.
• Administrative Controls: To properly execute and enforce all these controls, you have to have
administrative controls--rules, procedures, standards, and discipline. You don't want to wait until
disaster strikes, until a hacker destroys data, or an employee steals information and gives it to the
competition, to realize you weren't paying attention to what's going on.

Segregate the functions of your users. Whoever puts data in the system shouldn't be the one who
audits them for correctness or completeness. That's like having a bank teller be the only one who
ever counts the money in the till. Whoever develops and writes the software programs shouldn't
be the one to check the programs for errors.
33.3.2 Application Controls
We've talked about controls for the general use of an Information System. Application controls
are specific controls within each computer application used in the system. Each activity in the system
needs controls to ensure the integrity of the data input, how it's processed, and how it's stored and used.
• Input Controls :Are the data accurate and complete? We used an example earlier of a course
grade being entered incorrectly. If your system had a method to check the data on the input
documents against the actual data entered into the system, this kind of error could be caught and
corrected at the time it was entered. Many companies are using source data automation to help
eliminate input errors.
Managers can use control totals to determine that the documents used to enter data equal the
number of transactions processed by the system. For instance, if the Sales Department says it
entered data from 1,500 documents on April 21, were 1,500 transactions actually processed by
the system that same day? If the number is different, managers can investigate the discrepancy
and determine the cause of the mismatch.
Edit checks validate the data that were entered into the system. This control method is very
important for user-developed systems such as spreadsheets that record travel expenses for
employees. You could design an edit check into the spreadsheet that would verify how much
money employees spend per day on meal costs. If the amount exceeds that allowed by the IRS, an
edit check would warn the employee that he or she must have receipts to prove the actual amount
spent. The edit check validates the data before they are processed.
• Processing Controls: As the name describes, processing controls are used during the actual
processing of the data. If Suzy says she entered 100 items into the system on Tuesday, your
application program would have a method of checking and reporting the actual number of data
entries for that day. Not that you think Suzy is lying; you just need to have a method of verifying
and reconciling data entered against data processed.
If Sam mistakenly submitted two invoices for the same customer on the same day with the same
parts ordered, a computer matching control would catch the discrepancy and create a report that
can be used to investigate the error. Perhaps the customer really did order the same part twice on
the same day. More than likely it is an error that's better caught before it causes an embarrassing
incident for the company.
• Output Controls: Is the information created from the data accurate, complete, and properly
distributed? Output controls can verify who gets the output, and if they're authorized to use it.
You can also use output controls to match the number of transactions input, the number of
transactions processed, and the number of transactions output.
33.4 Security and the Internet

We can't stress enough the importance of security for Intranets, Extranets, and the Internet.
Organizations must control access through firewalls, transaction logs, access security, and output controls.
Software programs that track "footprints" of people accessing the system can be a good way to detect
intruders in the system, what they did, what files they accessed, and how they entered your system
initially.
The most important point is that you get the software, use it, and protect one of your most important
organizational resources.
Most people are reluctant to buy and sell on the Internet because they're afraid of theft, fraud, and
interception of transactions. To help make transactions secure, many companies are using very
sophisticated methods of protecting data as they travel across the various transmission mediums.
Watch any World War II movie and you'll see episodes of the good guys intercepting coded messages
from the enemy. The messages were scrambled and almost impossible to interpret. But the good guys
always won out in the end and unscrambled the message in time to save the world. Now we use
sophisticated software programs to encrypt or scramble transmissions before they are sent. Sender and
recipient have special software programs they can use to encode and decode the transaction on each end.
FIGURE 16.5
The above figure shows how encryption works using public and private keys. The keys are
created through complicated mathematical formulas. The longer the key, the harder it is to decipher.
That's the whole point of encryption. As the text points out, authentication, message integrity, and
digital signatures are the key elements of this system.
33.5 Developing a Control Structure: Costs and Benefits
You should be realistic about security and system controls. If you set up five layers of entry into
your Web site, people probably won't access it that much. They'll either ignore it or find a way around
your controls. You have to analyze the system and determine those areas that should receive more
security and controls and those that probably can use less.
Returning to our building analogy, the Executive Wing, which houses the CEO and other key
executives, will probably have more locks on the doors, more entry barriers, than the area the data
workers occupy. You can't check absolutely every person who traverses the hallways each day, but you
can have regular employees wear badges that readily identify them.
So too with the Information System. You probably don't want to incur the expense of checking
absolutely every transaction that is entered into the system, so you check a sampling of the data. Just
make sure the sampling is large enough to detect any exceptions.

Companies and governments systems constantly use risk assessments to determine weak links in
their physical building security. You can use the same methodology to assess the risk in your Information
System. Use risk assessment to develop cost comparisons for developing and maintaining security against
the loss potential.
33.6 The Role of Auditing in the Control Process
Companies audit their financial data using outside firms to make sure there aren't any
discrepancies in their accounting processes. Perhaps they audit their supply systems on a periodic basis to
make sure everything is on the up-and-up. They should also audit their Information Systems. After all,
information is as important a resource as any other in the organization. MIS audits verify that the system
was developed according to specifications, that the input, processing, and output systems are operating
according to requirements, and that the data are protected against theft, abuse, and misuse. In essence, an
MIS audit checks all the controls we've discussed in this lesson.
We mentioned earlier that a bank teller wouldn't be the one to count the money in the till at the
end of the workday. To ensure validity in an MIS audit, you would use someone totally disconnected
from the system itself. Usually companies hire outside auditors to verify the integrity of the system, since
they won't have any vested interest in hiding any flaws.
A good way to audit the Information System is to trace a typical transaction through the entire
system. The auditor might enter erroneous data in the system and test the safeguards used to alert the staff
about the error. An auditor might attempt an unauthorized access to the system or certain areas of the
system to examine the validity of the company's firewalls and other access barriers. Auditing the
Information System is too important to ignore or neglect. Schedule periodic audits and then correct any
and all flaws that are found.
Controls, general and application, must be designed into the system at the beginning, not as an
afterthought. General controls are concerned with the system software and manual procedures.
Application controls protect the data input, the data processing, and the information output.
33.7 Ensuring System Quality
There's a reason why we explained all those methods and procedures and processes in previous
chapters for building good, solid Information Systems. They ensure system quality so that the product
produced by the system is as good as it can be.
Software Quality Assurance
Just as you must assure quality of other products and other work, you must assure the quality of
your software.
Methodologies
It's easier to find the flaws in a system if you create all new systems and programs the same way
every time. If you want to check the system, fix the system, add to the system, or audit the system, you
won't have to spend time figuring out how it was built in the first place. In this case, predictability leads to
efficiency. The documentation that most people fail to develop makes it easier to determine how the
system is built and how it operates. Yep, it's a headache, but it's useful and necessary.

Resource Allocation
Most companies and most people spend the majority of their time in the programming phase of
system development. Not a good idea. Just accept the fact that the more time you spend analyzing and
designing a system, the easier the programming and the better the system. You will save a lot of time and
headaches and money. Honest, it really does work that way!
Software Metrics
Be objective when you're assessing the system by using software metrics to measure your
system. Emotions tend to cost money and use unnecessary resources. The text gives several good
examples of metrics you can use to measure your system inputs, processes, and outputs. For metrics to be
successful, they must be:
• Carefully designed
• Formal
• Objective
• Measure significant aspects of the system
• Used consistently
• Agreed to by users advance
Testing
You can't ignore testing as a vital part of any system. Even though your system may appear to be
working normally, you should still verify that it is working according to the specifications.
Walkthroughs are an excellent way to review system specifications and make sure they are correct.
Walkthroughs are usually conducted before programming begins, although they can be done periodically
throughout all phases of system development.
Once a system has been coded, it is much harder and more expensive to change it. We're
beginning to sound like a broken record, but it's important that you understand and remember that the
more work you do before the programming phase begins, the less trouble you'll have later. You can't just
start pounding the keyboard and hope everything works out okay.
Quality Tools
Just as you would manage any big project--a house, a highway, a skyscraper--you must manage
the entire systems development project. You can do it much easier using project management software
that allows you to keep track of the thousands of details, deadlines, tasks, and people involved in the
project. This type of software also helps you keep everything in sync.
Data Quality Audits
We spoke earlier of MIS audits, which check the system and its general controls and application
controls. Data quality audits verify the data themselves. Many of the principles we discussed in the MIS
audit apply to this type of audit. A company should formally record the number and types of errors
customers report. Using this record can help managers do data quality audits by giving them ideas of
where they can start looking for problems or areas that need to be improved.

A few comments regarding the three items in the text:
• Survey end users for their perceptions of data quality: How do they see it? Looking at your
data through a different set of eyes can reveal problems you weren't aware of.
• Survey entire data files: This can be expensive and time-consuming, but very fruitful.
• Survey samples from data files: Make sure the sample is big enough and random enough to
uncover problems.
It's better for the company or organization to uncover poor quality data than to have customers,
suppliers, or governmental agencies uncover the problems. Managers can ensure Information Systems
quality through methodologies, adequate resource allocation, software metrics, testing, and the use of
quality tools. If data quality suffers, it's a sure bet the information obtained from that data will be of poor
quality also.
33.8 Summary
Companies have to trust employees, consultants, and business partners, but this group presents
the greatest security threats. Natural disasters are a threat to the physical assets, but their business damage
can be minimised by having up-to-date backups, and a disaster plan with arrangements to run operations
offsite if a disaster strikes. The internet provides more avenues for attack of outsiders – particularly from
viruses spread through e-mail messages. The best defenses are to install all current operating system
patches, to assign access rights carefully, and to monitor the computer usage with an intrusion detection
system. However, denial of service attacks is particularly hard to prevent.

UNIT VI
Lesson 34 – International Information Systems
34.1 Introduction
The world just keeps getting smaller and smaller. No company can afford to ignore foreign
markets or the impact of foreign competition on the domestic business environment. You have to adapt to
the changing faces, literally, of your competition and devise a plan to bring your organization into its
focus.
34.2 The Growth of International Information Systems
Globalization is possible even with very small businesses because of the technological advances
in computer networks and telecommunications. Is your organization developing a Web site for E-
commerce? You'd better have it available in 4 or 5 foreign languages. That's what it takes today to
compete.
Developing the International Information Systems Infrastructure
You must have an Information System in place that will support the communications,
coordination of people and products, and order processing for both domestic and foreign markets
(international information systems infrastructure). You have to understand the characteristics and
individual needs of foreign markets, just as you need to understand the domestic markets.
Wal-Mart learned the hard way that it couldn't just walk into a foreign country and build a store
mirroring those in the United States. Sales were very low and the products just weren't moving in many of
its foreign stores. It wasn't until Wal-Mart analyzed store designs and layouts, quizzed potential
customers, and focused on foreign operations without the bias from domestic stores that the company
realized it was a much different world outside the U.S. It rearranged stores, stocked more items from
within the countries, met local customers' needs, and dramatically increased sales.
Don't start creating all those juiced-up Information Systems as soon as you decide to pursue the
foreign marketplace. We said before that every Information System implementation plan must be in
harmony with the basic business plan. In fact, you must first develop the overall business strategy for
entering the global arena. Then and only then can you begin to think about how the Information System
will be synchronized with the basic strategy.
The Global Environment: Business Drivers and Challenges
The following list gives you an idea of some of the global business drivers, factors influencing
the direction of businesses that organizations must consider in today's environment.
General Cultural Factors

• Global communication and transportation technologies
• Development of global culture
• Emergence of global social norms

• Political stability
• Global knowledge base
Specific Business Factors
• Global markets
• Global production and operations
• Global coordination
• Global workforce
• Global economics of scale
Perhaps the most important challenge facing corporations and companies wanting to open foreign
markets is that of the global culture. We're beginning to share more culture because of increased
telecommunications and the Internet. However, when you are merging two entities, one domestic and one
foreign, into one business, the culture of that merged organization can be an important influence on how
well the company does.
Countries that we traditionally have thought of as Third World, or underdeveloped, are emerging
as forces to be reckoned with. Chile, Brazil, Mexico, and others play as big a part in the global economy
and its effect on worldwide trade as our own country.
Advanced telecommunications systems now allow companies to work around the clock and
around the world. Companies may choose to locate parts of their corporate offices in other countries
because they fit better with the corporation's overall global strategy in that location. Ask yourself this
question: Who says all corporate offices must be located in the continental U.S.?
You know that doing business in foreign countries is not all that easy. There is tremendous risk
associated with global businesses. Russia is a prime example of how difficult it can be for businesses to
establish themselves in foreign markets amid political turbulence and disorder. Just when your company
thinks all is well with its foreign establishment, a terrorist attack can put a crimp in the best-laid plans.
It's not always that desperate, but companies should make a point of adapting to foreign cultures,
just as Wal-Mart had to. For instance, in many countries afternoon siestas are the norm. Other countries
have religious and historical laws that prevent women from working or accepting jobs that place them in
the position of supervising men. The point is that not everyone thinks, works, acts, and plays like
Americans.
A startling example of how domestic and foreign cultures and laws collide is the case of
individual information and privacy. In many European countries, companies and governmental
organizations are not allowed to collect certain pieces of information about individuals. If they are
allowed to collect the information, there are very strict laws about how they must store it and who can
access it. The individual must be notified first before the information can be given to another entity.
Contrast that with the American business practice of collecting individual information without the
person's knowledge and then selling that data to whoever pays for it. Corporations and companies must
reconcile these differences in order to allow transborder data flow between their merged Information
Systems.
If you thought building an Information System for an organization doing business only in the
U.S. was tough, think about some of the factors we've just discussed and then imagine how you would
build a system that takes disparate practices into account. So why do companies even attempt to build
themselves into global merchants? Because the potential payoff is enormous!

34.3 Organizing International Information Systems
First you have to decide what you're going to do--you have to choose a strategy. Then you have to
organize your business around this strategy. The last step is to build the system that will incorporate the
first two.
Global Strategies and Business Organization
Strategy
Business Function
Domestic Exporter Multinational Franchiser Transnational
Production Centralized Dispersed Coordinated Coordinated
Finance/Accounting Centralized Centralized Centralized Coordinated
Sales/Marketing Mixed Dispersed Coordinated Coordinated
Human Resources Centralized Centralized Coordinated Coordinated
Strategic Management Centralized Centralized Centralized Coordinated
The above table shows the four main strategies that can form the basis for a global organizational
structure. Let's dissect each one.
• Domestic exporter: Most operations are located in the domestic country, and the company
exports products to foreign companies. A company located in India which imports rugs to the
United States would fit this category. All corporate offices are in India, and products are sent
to distributors in the U.S.
• Multinational: Part of the company is located in the domestic country, and other parts are
located in foreign countries. Japanese automobile manufacturers might be in this category.
Years ago we complained loudly in the U.S. about cheaper Japanese-made cars flooding our
markets and demanded that they produce vehicles in our country if they wanted to sell them
in our country. So they left their corporate operations in Japan, built some factories in
America, and satisfied our concerns.
• Franchiser: Some operations are located in the domestic homeland, while extended activities
associated with the product are conducted in foreign countries. Starbucks Coffee Company is
a primary example of this type of global business. Its corporate headquarters is located in
Seattle, Washington. Recipes for products are developed in Seattle. Some coffee beans are
roasted in Seattle and then shipped to coffee shops in England. These operations are
franchised to keep quality controls in place, and the final product is made in the local area.
• Transnational: One globe, one company. DaimlerChrysler is the perfect example of a
transnational corporation. Its Web site (http://www.daimlerchrysler.de/index_e.htm)
describes it as "the first automotive, transportation and services company with a truly global
structure." Corporate headquarters are "located in Stuttgart, Germany and Auburn Hills,
Michigan, USA." DaimlerChrysler did business in 200 countries with 441,500 employees at
the end of 1998. Manufacturing facilities are located in 34 countries around the world. Bill
Vlasic's article in The Detroit News, Jan. 6, 1999, quoting Andreas Renschler at
DaimlerChrysler, says: "The biggest difference between people is not the national culture. It's
how you think things have to be done. We have to integrate their experiences, and use the
best of the best." (Note: the text lists Chrysler as a multinational company. That was true
before it was bought by Daimler.)

Global Systems to Fit the Strategy
Once you've decided which global business strategy to follow, it's time to decide how your
Information System will support it.
FIGURE 17.2
Global strategy and systems configurations
The above figure gives you an idea of the type of Information System which will best support the
different business strategies. To summarize the text definition of each type of system:
• Centralized: Everything is located at the domestic home base.

• Duplicated: Development occurs at the home base; operations are located at foreign
locations.
• Decentralized: Each business unit, regardless of location, has its own system.
• Networked: All business units participate in development and operations.
Reorganizing the Business
You have to decide what your overall business goals are, what makes sense for your organization,
fit the Information System structure to your needs, and never lose sight of new opportunities.
1. Organize value-adding activities along lines of comparative advantage. Starbucks has to

decide where to locate the marketing function to maximize its potential. Perhaps it can
centralize this function in Seattle so the theme of the current marketing campaign is the same
in every coffee shop. It is very picky about maintaining quality control over the bean roasting
processes. Is this process better left in Seattle, or should it be moved to England to maintain
freshness and high quality?
2. Develop and operate systems units at each level of corporate activity--national, regional, and
international. Wal-Mart would probably maintain small Information Systems in each foreign
country to support its local operations. A regional Information System would support entire
geographic areas such as Southern Europe. Each of these regions would be connected to the
main system in the United States that supports activities on a global scale.

3. Establish a world headquarters and a global chief information officer (CIO) position.
DaimlerChrysler has one person who is responsible for the entire Information System
spanning the globe. While smaller units spread throughout the world would actually carry out
the operations, the CIO would ensure total integration of all local, regional, and global
systems.
34.4 Managing Global Systems
Take all the problems and challenges you can think of when developing a single Information
System for a domestic operation and then multiply it by tens or hundreds. Now you understand the
problem of developing a system to support a global operation.
Management Challenges
• Agreeing on common user requirements
• Introducing changes in business procedures
• Coordinating applications development
• Coordinating software releases
• Encouraging local users to support global systems
ABLE 17.4
A Typical Scenario: Disorganization on a Global Scale
The lesson gives a wonderful scenario of challenges facing corporations wanting to develop
Information Systems to support global operations. Bring it a bit closer to home: You're part of a team of
12 students with an assignment due by the end of the month. You have to develop a Web page to support
three different presentations given in three different sections of the same class. Each of you will receive
an individual grade in addition to a team rating. You've been given minimal resources with which to
complete the assignment.
All 12 team members approach the project from different perspectives, different values, different
needs, and different goals. Some like to start early and do a thorough job; others never start any
assignment until the day it's due. Some team members have Apple computers, some have PCs; some have
the most current software, others rely on programs created 5 years ago which are incompatible with
today's software. All are busy with jobs, other classes, and other interests; you find it nearly impossible to
meet in order to coordinate project tasks.
Now you can begin to understand the difficulty managers face when they are organizing or
reorganizing global commerce.
Strategy: Divide, Conquer, Appease
Only a few business processes use global core systems. Others are divided among regional and
local systems. Let’s look at the tasks that need to be accomplished.
• Define the Core Business Processes

Decide how your business processes are divided among global, regional, and local units. Which
location does each process better than the others? Make sure you keep cultural and political
biases out of the way when deciding which location is better. Carefully analyze each task and all
available resources to support the process in each location. You may be surprised to learn that it's
cheaper and more efficient to store manufactured goods separately from where they are produced.
• Identify the Core Systems to Coordinate Centrally
Once you've identified and analyzed each workflow process, you can figure out which to
centralize and which to keep decentralized. Some decisions will be based on political influences,
and some decisions will be made to appease various groups within the organization. Some
decisions will seem totally rational, while others may seem irrational.
Once you analyze and determine which core business processes to keep locally, establish
regionally, or maintain in transnational centers, you can build your system. It's obvious you
wouldn't decide that a process should be done locally and then build a transnational Information
System to support it.
While determining how and where to establish your core processes is the first step, part of the
analysis must include the implications of building an Information System to support them. For
instance, if you decide to create a transnational unit to handle customer technical support, how
will your Information System support the data storage associated with customer information?
How will you handle the political and cultural influences that determine access and distribution of
the personal information associated with your customers? While it may make sense to create this
unit on a transnational basis, you might decide that an Information System to support it is not
feasible.
• Choose an Approach: Incremental, Grand Design, Evolutionary
Don't bite off more than you can chew. If you try to fulfill your development and implementation
plan all at once, combining every task into one huge project, you're setting yourself up for failure.
It may indeed be cheaper to do it that way, but you have lots of considerations other than cost.
There are political, cultural, and historical biases to overcome. Remember, change is extremely
difficult for people to accept. You have to convince everyone, especially the executive branch,
that your plan is possible and best for the company.
Many companies choose to take an evolutionary approach to merging disparate Information

Systems. That is, they pick the most critical areas, such as finance, to merge first. Then they move
on to perhaps Sales and Marketing. Corporate Strategic planning may be next, and last might be
Human Resources systems. The point is, you can't do it all at once.
• Make the Benefits Clear
You have to convince the organization's managers that the impending changes will benefit them
in the long run. Get them behind your effort and use them to help you develop and establish
system changes. They need to understand how they can enhance their own operations through the
new system.

Global systems can help an organization improve its vertical and horizontal operations. If a
political conflict interrupts sugar supplies, a global system can shift the flow of that vital supply
to another region. As global operations continue to expand, corporations are realizing the benefits
of having multiple geographic locations from which they can operate virtually uninterrupted.
Should a region or operating unit experience a disruption in sales, such as we've seen in Asian
markets in the last few years, the economic burden of the declining profits can be spread to other
units of the global company. The economies of scale that corporations are realizing through
global operations is tremendous. No longer does a company have to build individual production
units in every country in which it wants to sell its products.
• Implementation Tactics: Cooptation
Get the opposition on your side as quickly as possible. Cooptation is the process of getting the
nay-sayers to help you determine the solution to the problem without giving up total control of
the change process. Persuading them to help you is far better than beating them into submission.
Let's say that the German unit of your transnational company is the best at writing graphical user
interfaces for your order processing system. Have those people create and implement the new
GUI in their unit and then transport the interface to the French unit. The Asian unit may be the
best at writing middleware software that connects a Unix operating system to a Windows
operating system. So the Asian unit would do that part of the integration and then expand it to the
European and U.S. units.
The central management office in Finland would still determine the overall structure of the
project, but individual units could be assigned the design, development, and implementation. That
way, they all begin to gain ownership for the success of the new system.
We mentioned earlier the need to determine which core business processes were done best in
particular units. We trust you did that because you can now use the results to help decide where
various processes can best be developed. The centers of excellence for each core business process
can determine the initial requirements for the applications, do all the analysis, design the
application, and then test the new procedure in a central region. Remember the phased conversion
process discussed in Chapter 11? Use it to install the new system throughout your global
community.
• The Management Solution
Management's biggest task is to manage the changes that must take place in a global company. As
we mentioned earlier, the changes are more difficult and complex because of the added
characteristics of politics, culture, and language. Here are some guidelines:
o Agree on common user requirements: Keep the list of core business processes short
and simple. It's easier to implement. Don't lose sight of the common goal of integration.
o Introduce changes in business procedures: Your legitimacy is enhanced by how well

people accept your authority as a change agent. If you establish yourself as
knowledgeable, competent, willing to accept input from others, and if your vision of the
end result is sound, you're more likely to succeed. Give other people some ownership of
the change process, and they'll be more than happy to help you and the company succeed.

o Coordinate applications development: Communicate, communicate, communicate.

Tell people what's going on; don't surprise them about anything. Change is difficult
enough without people feeling they're getting blindsided.
o Coordinate software releases: Try to get everyone working from the same sheet of
music at the same time.
o Encourage local users to support global systems: All participants will want to do it
their way because that's what they are most comfortable with. Your task is to convince
them that they may need to adapt to a new way of doing business for the overall good of
the company. Again, give them ownership without giving up total control.
You'll still have a difficult time because you'll have so many things to work on at one time. That's
why we suggest using the strategy of one step at a time, little by little.
34.5 Technology Issues and Opportunities
The advances in technology, and the desire to seize new business opportunities presented by the
advances, is what induces organizations to undertake the changes we've been discussing. However, the
same things that drive the desire can create the headaches, as Table 17.5 points out.
Problems of International Networks
• Costs and tariffs

• Network management
• Installation delays
• Poor quality of international service
• Regulatory user requirements
• Changing user requirements
• Disparate standards
• Network capacity
Main Technical Issues
Hardware, software, and telecommunications are special problems in a global setting: you need to
synchronize, harmonize, integrate.
Hardware and Systems Integration
Most global companies are a result of merging several units into one cohesive success story.
When the merger takes place, you can't just buy all new hardware and software. It's too expensive for one
thing, and it probably won't make sense. You have to figure out how you're going to get all the different
types of hardware to work together in one seamless system. You have to get one type of software
"talking" to another type of software.
You've already figured out your core business processes. Now you should figure out which type
of software, some of which may already be present in the various units of the merged organization, is the
best to use for each process. If you're currently using proprietary software and choose to keep it, you will
probably need a bridge, or middleware software, in order for it to work across all your business units and
regions.

Each region of the business is used to working according to its standards. For instance, the
German unit has been storing data according to its standards and definitions. The Asian units have been
using different standards and definitions to accomplish the same task. The idea is to get the data
conformed to one standard across all units so that it can be shared efficiently and effectively.
Each unit is going to have to adapt in order for that to work. That's where the central office comes
into the picture. It will have to determine the end goal of the business and the final information
requirements needed, take the best of the best, adapt the rest, and solidify all the units into a cohesive
whole.
Connectivity
Most Indians don't think twice about the reliability of our telecommunications systems. When
you pick up the phone in Peoria, you expect it to work and work well. When you log onto your Internet
Service Provider, you expect instantaneous connections at relatively high speeds. When you travel from
state to state, you know that the telephone system will work the same in Texas as it does in Pennsylvania.
And you expect reasonably low rates for telephone service, television, and Internet service. Not so in
foreign countries.
When you're trying to establish global communication networks, you must work through the
maze of various laws, high to low levels of service reliability, different rate charges and currency
exchanges, and different companies and governments controlling the telecommunication systems.
You can attack this problem three different ways:
• Build your own network: very expensive, time consuming, and not an option in some countries.
• Patch together a public network: very expensive, time consuming, and a hodgepodge of services.
• Outsource telecommunication requirements: economies of scale, rely on previous experiences of
outsourcers, limited to data transmissions.
As the Internet grows outside the U.S., more corporations are turning to it as a solution to the
connectivity problem. To be sure, there are still problems associated with using the Internet. But its open
standards, ease of use, and expanding connections offer viable solutions.
Software
We mentioned before that different foreign units probably have divergent standards for their
Information Systems. Trying to merge databases from several domestic units is tough enough. Trying to
merge databases from different countries can be quite troublesome because of the added layer of politics,
traditions, and languages.
Even though the English language is widely accepted in foreign business circles, and it seems
reasonable to build software programs based on that language, the decision will create its own problems.
Foreign business units may resent having to use applications written in a different language--what's
wrong with Spanish, they may say? While most of the upper management of the foreign business units
may understand English and can use it, will the data workers know the language, or will they have to
learn it at the same time they are learning a new Information System?

Traditionally, companies have merged their transaction processing systems into one or a few
worldwide applications. Now they are looking to do the same with collaborative workgroup software, and
well they should. We mentioned at the beginning of this course that many companies are "time-shifting"
their projects around the world.
A person in New York City may work on the new advertising campaign all day Tuesday. When
she's done for the day, she may send the project electronically to a collaborator in New Delhi, India. He
will work on it for several hours and forward it on to the third team member located in Munich, Germany.
All of them need to be able to communicate using collaborative software in a common language.
New Technical Opportunities and the Internet
As with everything in our world today, the Internet is offering businesses vast new opportunities
and challenges. The virtual private networks (VPNs) that we already discusses are eliminating many of
the bottlenecks that companies have found in the their telecommunication systems and filling the void of
critical communication systems in foreign nations. With the advancements in cellular and satellite
telephone systems, emerging nations can forego the cost of stringing wires through rural areas by using
new technology and still offer their people conveniences they haven't had before.
Reliance on the Internet to overcome disadvantages in telecommunications systems will answer

some of the problems companies have had. But, as we noted before, the Internet will create other
problems that global corporations will have to solve.
34.6 Summary
Global businesses must devote time and attention to understanding the cultures of countries in
which they want to do business. Not only must they merge their business units, they must also merge their
people into a cohesive team. They must understand and deal with external factors in both the domestic
and foreign environments. There are four main global strategies businesses can use to organize their
global efforts: domestic exporter, multinational, franchiser, and transnational. Determining the global
strategy will help a business determine its Information System structure.
Analyze each workflow process and decide which business unit can best carry it out. Go with the
best of the best. Match the structure of your Information System to that of your core business processes.
Make the benefits clear to all levels of the organization. Use cooptation to encourage ownership of the
system. Manage the changes in the Information Systems as intensely as you manage anything else.
Differences in hardware, software, and telecommunications throughout the organization and the countries
in which you're doing business pose tremendous challenges in integrating disparate business units into a
cohesive global whole. The Internet can help resolve some of these issues, though it will create other
problems.

MANAGING GLOBAL SYSTEMS
A Typical Scenario: Disorganization on a Global Scale

• A traditional U.S. multi-
multi-national consumer-
consumer-goods
company, also operating in Europe, wants to expand
into Asia
• It knows it must develop a transnational strategy and
supportive IT system structure
• It has dispersed production and marketing to regional
and national centers while maintaining a world
headquarters and strategic management in the U.S.
• The result: a hodgepodge of hardware, software, and
communications (e.g., incompatible e-
e-mail systems,
different manufacturing resources planning, different
marketing / sales / human resources systems)

UNIT VI
Lesson 35 – Managing Infrastructure and Enterprise Systems
35.1 Introduction
Unfortunately, businesses haven't always worked as a unit. Production created business processes
separately from Accounting. Sales and Marketing had their own systems, and so on. Usually none of the
systems linked into the others within the same company (application specific view). Most systems were
intentionally created separately, since technology did not allow an entire organization to feed from one
big, integrated system.
Now technological advances have given corporations the computing capacity and the tools to
create a single system that can link all parts of the organization. With the explosion of the Internet, the
ability to bring vendors and suppliers into the organization's system is now available through enterprise
computing.
35.2 Managing IT Infrastructure and Architecture: Enterprise Computing
Compare the difference between the following two figures, the old view of systems, and, the new
way of thinking about Information Systems.

Basic Concepts of Enterprise Computing
The four basic concepts of enterprise computing are compared in the following table..
The information technology investment portfolio is concerned with the amount of money firms
spend on Information Systems and whether the organization is receiving a fair return on its investment.
With "Internet-centric" companies, this concept can be skewed or simply thrown out altogether. Many of
these companies are more concerned with the strategic value of their Information Systems and don't
expect a return for several years. Amazon.com loses millions of dollars every quarter but it continues to
focus on brand building rather than a real dollar return on investment.

Just as every town and city in the world relies on basic facilities to function, such as roads and
utilities, corporations rely on the proper amount of hardware, software, and people to create and operate
their IT infrastructures. Firms should continually review and question whether they have the right mix of
each to carry out their business plan.
How do companies intend to make money? After all, isn't that why businesses exist? When
businesses answer that question, they have found their business logic. Combine the IT infrastructure with
the business logic, in the right mix, and you have the information architecture necessary to make the firm
a success.
When developing enterprise computing systems, there are no cookie cutter answers to the tough
questions management must explore and answer. The company needs to develop a plan, complete with
graphics and descriptions that spell out how the business processes will be supported by the Information
System and how the company expects to excel using enterprise computing.
It's not enough to tell your suppliers they will be able to use your Information System. The real
question is how the key business processes will be enhanced by allowing suppliers to tap into the
information system.
How will you know if the organization is really better off with the enterprise computing system?
You should measure the company's performance after implementing the new system with the its
performance before installation. That's the only sure way you'll know if the effort has paid off.
Industrial Networks and Trans-enterprise Systems
Selling paper towels may seem like a very simple task. Have you ever thought about the supplies
that go into that roll of paper towels? Where do the raw products come from? Once the towels are made,
how do they get on the shelves of your local grocery store? Many suppliers and vendors are involved in
the product from start to finish: it's not produced solely by the manufacturer.
What if the maker of the paper towels was able to control the product lifecycle better and thereby
reduce costs by including the suppliers and vendors in the total process? That's what industrial networks
are all about.
The dilemma occurs when various manufacturers develop separate systems for their products and
then expect the suppliers to join in. If a supplier deals with several different manufacturers, it could end
up with several different systems that don't mesh.
Business Drivers: The Changing Business Environment
It's not your father's business environment anymore. We've seen tremendous changes in the world
over the last ten years, many of them driven by technological changes and advances. The following table
describes the business factors that drive change and highlights the impact of each on companies trying to
keep up.

The factor associated with all the drivers of change is that businesses aren't as free to raise prices.
They must cut costs in order to stay competitive and to expand their markets. The emerging global
economy has put the brakes on simple price changes to enhance the bottom line. Many companies have
been able to hold the line on costs by updating their IT infrastructures and reshaping their IT
architectures.
Businesses also realize they cannot allow islands of information to exist in their organizations but
must have a cohesive Information System that feeds information from one unit to another. . Older systems
didn't allow for cross-utilization of information. Companies with these older systems are now realizing
the severe disadvantage they suffer if they don't use information as a key resource.
In 1999 Bill Gates, Chairman of Microsoft, Inc., published a book called Business @ the Speed of
Thought. The tile alone speaks volumes about how companies are beginning to view information and how
fast information-based products and services change. Today's innovation is tomorrow's dinosaur. Products
and services that used to take months and years to develop can now be brought to market in weeks or
days.
In the past businesses were judged by how well they functioned within their own business. Now
they are branded by the entire industry to which they belong. Vehicle manufacturers are judged on the
value chain they help create within the entire industry, from the procurement of raw products to the
impact on the environment from the vehicle emissions.
Many Internet-based companies are racing to build brand awareness and improve processes and
products. Charles Schwab online brokerage, for example, is far ahead of its competitors in the delivery of
online stock trading. It seems reasonable to think that Schwab could take a rest, because it will be quite a
while before the competition catches up to the superior infrastructure and product delivery it's built. Don't
be so sure. Other brokerage firms are forging ahead and building their own systems to take advantage of

new enterprises on the Internet. No company can afford to rest for even a little while lest the competition
beat it at its own game.
Technology Drivers: The New Networked Environment
Just five short years ago, the term virtual organization didn't exist. Now, more and more
companies are adopting this concept because of the technological drivers in enterprise systems and
industrial networks. Virtual partnerships are possible and make sense because of advances in technology.
If a company wants to embark on a new service, it doesn't necessarily have to work alone. It
doesn't have to hire the people, purchase the hardware and software, and struggle with all the
development costs by itself. It can partner with another company, use networks to enhance product
delivery and keep costs down. A company using enterprise computing and industrial networks can go
places not possible a few short years ago.
An Ideal Model of Enterprise Computing
In an ideal world, the business drives the technology and not the technology the business. To have
this happen, four conditions must exist:
• The right amount of infrastructure

• Close coupling of the architecture and the business processes
• Adequate strategy to cope with environmental and competitive pressures
• An adequate governance model to align the IT infrastructure with the business strategy
35.3 Managing the New IT Infrastructure
How do you get information, the right kind and the right amount, from the environment into the
organization and then move it throughout the organization? Let's look at some ways to do this
successfully.
Elements of the New IT Infrastructure
The old days were simple: Your organization probably had a huge mainframe sitting in the
basement with dummy terminals spread throughout the company.. All data were maintained on the one
system and specialists were the only ones allowed to touch it.
Now you must try to mesh remnants of the old legacy systems with the newer servers which have
countless clients connected to them. On top of that, employees are more mobile nowadays and need cell
phones. Not just plain old cell phones: These cell phones must be connected to the company's Intranet so
product data can be downloaded while the salesperson is sitting thousands of miles away in a meeting
with a potential customer. The icing on the cake are all the users who want to use fourth-generation
software to build their own applications using downloaded corporate data.
Each element of the new IT Infrastructure poses its own unique set of challenges not just to the IT
staff, but to the organization as a whole. Sally in Marketing just can't understand why she can't develop
her own set of data and store it on her desktop. Tom in Sales wants to buy the latest PalmPilot device to
use in customer meetings and can't figure out how to connect it to the enterprise computing system. The
newest product supplier needs help accessing the corporate Extranet in order to get information added to

its own database. The local phone company is short of help and can't get the extra T1 transmission line
installed for Internet access for three more months. The outsourcing consultant company needs to know
how soon the company will be ready to test the newest order-processing application. The CEO needs
someone in her office right away to help her set up the latest version of the Internet browser.
Key Infrastructure Decisions
Many companies have five-year plans for their products and services. That's good; companies
should have an idea of where they want to go. As the text points out, "The overarching question is 'What
business capabilities are we seeking?'" To say that arriving at the answer is difficult is a drastic
understatement.
Most of these technologies seem to be obsolete or outdated a few months after they are
purchased. The key is to select the technologies that fit somewhere in the middle of what you are
currently using and where you want to be in a few years.
If your organization is currently using WINTEL (Windows operating systems and Intel
processors) technology as the basis for your system, you shouldn't purchase Apple machines. Should the
organization decide to move towards technology that's not compatible with the current infrastructure,
plans need to be made and funds allotted for some type of middleware that will allow compatibility for
the time being.
Software development projects must be judged on whether the company adopts a policy to build
its own, use a pre-written specialized program, or go with general off-the-shelf software. We've discussed
the pros and cons of each of these in previous chapters. The important thing to remember is that the
software must support the business processes, both current and future.
As a company decides on the type of software to use, it must decide how the software will be
deployed. Management needs to take a hard look at where it intends to be five years from now when
deciding this question. Will the software be an enterprise-wide program, managed regionally, in separate
business units, or installed on a local basis with each geographic unit operating independently? The
decision made at this point will set the stage for how easy or difficult future expansion will be.
In the old days organizations had one choice for telecommunications: AT&T. That's was it. Now
the choices are as broad and varied as the globe itself. Does the company go with a local, private provider
or a global, public provider, or a combination of the two? If you need the most advanced security for data
transmissions you may need to build your own telecommunications network; but this is very expensive
and very limiting.
Connecting Infrastructure to Strategy: Governance
How do you know that the decisions you make regarding the IT infrastructure are the right ones
for the organization? By letting business goals and strategies guide you. Focusing on the goals will
prevent the business from purchasing unnecessary technology just because it's there. Having the
organizational strategy decide the direction of the infrastructure will curb the impulse to grab the newest
toys with the neatest bells and whistles.
Four levels of the organization should govern decisions about the IT infrastructure:

• CEO, CIO, and the strategic council

• Operational groups
• Business units and regional units
• Specific business functions
Dealing with Mergers and Acquisitions
If you can't build it, buy it. If you can't beat the competition, join it. Spread your risks by
expanding into other product lines. Often companies decide it's better to merge or acquire other
companies than to go it alone.
When a company does decide to merge with or acquire another company, it usually makes the
decision from a strategic point of view. The senior executives are more concerned with how the new
company can help them win new customers, enhance current products or services, or beat the
competition. Very little time is spent exploring how the IT infrastructures will mesh with each other. Yet
the inability to bring divergent systems together can derail the new enterprise.
Executives should learn to consider the impact information technology will have on making the
new organization a success. Which system will they keep as the predominant system? How will the data
be merged? Will new applications be required? What kind of IT staff will be needed for the new system?
Of course many of these same types of questions must be asked of every business unit in the
combined organization. However, since the Information System plays such a critical role in the success or
failure of the new company, these are very important questions to ask specifically of the IT department.
The business environment may drive the merger and/or acquisition, but information technology
makes it happen--or not happen.
35.4 Enterprise Systems
Now that the company has agreed to use enterprise computing and the grand design approach to
solving problems, what are the effects on the IT infrastructure?
• Experimentation with other designs is limited.

• Significant resource commitments are necessary.
• This approach is nonadaptive.
• Success depends on faithful execution of all its elements.
Enterprise Systems: The Vision
What is the scope of enterprise systems, and what are they supposed to accomplish? Here's the
dream:
"No more islands" is one of the great promises of enterprise computing. A single system will
serve all areas of the organization and all data and information will be managed from a single point of
view--that of the total organization.

Managers will manage from a firm-wide vantage point. They won't make decisions in isolation
from other business units. Whatever they do in their own department will be available to all other
business units.
All for one and one for all. Data will be managed for the total organization and cross-fed to and
from individual units. This holds the promise of easy expansion to accommodate new business ventures
and new technologies.
The organization will truly be driven by the customer and not by traditional production and
supply factors. The customer will dictate that individual units act in a more cohesive manner and provide
"one face" representing the entire organization. The business is then able to respond faster and more
efficiently to competitive markets and add new products and services for the customer.
Enterprise Systems: The Reality
Lofty goals indeed--and necessary ones in today's business environment. Here's the real story.
Many of the systems in place today have been around for a long time--much longer than expected
in many cases. The systems have created dependencies that may be difficult to break. Enterprise systems
promise to replace these aging systems with new hardware and software from top to bottom. And they
promise to do it quickly. Take everything you've learned in this course and ask yourself if it's truly
possible to do this so quickly.
There are some things you can't put a price tag on, such as improved customer relations or better
employee morale. Yet these are the very benefits enterprise systems touts as their cornerstone for success.
Some benefits won't be realized for years, especially if the firm installs the enterprise system in a
piecemeal fashion. But the bean counters, bless them, want concrete evidence of the financial payback on
the investment.
Even though enterprise systems promise improvements over older legacy systems patched
together over time, do they really deliver on that promise? Do you have the technical knowledge available
within the firm to conquer the new hardware, software, business process changes, and persware
development necessary to make the new system a success? Or are you just gaining a whole new set of
problems similar to the old problems but with new names?
Building bridges between the old system and the new can be worse and cost more than
continually expanding and improving the old system. The new enterprise systems offer opportunities, but
you'll still be relying on the old system for some time.
Some business assets can be sold and bought: new equipment that makes the production line
more efficient, streamlined customer order processes, new trucks that reduce shipping costs. But how do
you buy or sell strategic advantages that come from enterprise systems? Moreover, how do you take
advantage of the new opportunities offered by the newer systems? And last, if all your competitors are
using the same enterprise system, how do you create differentiation for your suppliers and customers?
35.5 Industrial Networks and Extended Enterprise Systems
When you're trying to imagine industrial networks, think about the automobile manufacturers.
Ford, GM, and DaimlerChrysler make cars and trucks. Do they make every part of every car and do they

actually sell every car? Do they make the tires? Do they make the starter assemblies? Do they own the
trucks and trains that transport the cars to the dealers? Do they own the dealers?
No; when you think about it, the Big Three are assemblers of vehicles. Goodyear, Michelin, and
others make the tires. Delphi Industries makes the starters. Independent truckers and the railroad lines
own the transportation. Individual people own the dealerships. But they all work in concert to get your
favorite car or truck to your doorstep. An industrial network links them all together in a vertical chain.
Industrial Networks: The Vision
How we'd like it to be:
When you order a new vehicle, the information is passed from the dealer or Web site to the
manufacturer. At the same time, information regarding the specifications of your new car are passed to
the parts suppliers, the tire makers, and the truckers. Everyone along the way knows what you ordered
and when you expect delivery.
If one piece of the vertical network needs help or information or improvements, all other parts of
the network can help. Managers won't think of their individual companies, but will act on behalf of the
entire industry.
Managers, specifically IT managers, will be required to view their information infrastructures

from the vantage point of an entire industry and not their individual companies. Suppliers won't benefit
from having three or four different platforms thrust on them by various manufacturers.
It may seem strange that a company can enhance its business capabilities by joining forces with
competitors. Industrial networks and the promise of greater efficiencies and lower costs demand that
firms do so. The example in the text of Dell and IBM working together to increase their sales is an
excellent snapshot of the future of other industries.
Industrial Networks: The Reality
Landmines abound in this new paradigm. Here's the real story.
Companies have always safeguarded information to increase their competitive advantage. And
now they're just going to throw open the doors and give critical information to the world? Not quite.
Businesses will still control the release and flow of information in one of three ways:
• Hierarchy: One company decides for the rest how information will be disseminated, who
gets it, and how they are allowed to use it.
• Market interface: Each company is on equal footing with its partners and lets the
marketplace drive their participation.
• Network interface: A third party or a steering committee of sorts manages the network.
Who will pay for what and at what percentage? Will all partners in the industrial network share
the costs equally? How will suppliers and vendors be charged for the benefits they receive? How will a
company determine its return on investment, especially when the return may be in less tangible benefits?

Systems break down and require upgrades. Who will be responsible for maintenance of the
system? When a firm relies solely on itself for information, that question is easily answered. It isn't so
clear when a company relies on an industrial network shared by other companies and competitors.
Divided loyalties between a company's own internal network and the industrial network is a very real
concern.
Steps to Building and Managing ES and IN
Questions managers need to ask themselves before embarking on the long voyage:
1. Where are you now in relation to the technology and the other firms? On a piece of paper, draw a
circle and write inside "You are here." Describe your company in terms of its technology
knowledge and describe other firms in the same way.
2. Know who you are and where you want to be: Draw another circle and write inside "Where you
belong." Now fill in everything in between. Get input from various sources. Be honest with
yourself and your company.
3. Devise a five-year plan: Sketch out ideas of what your company could look like in the next five
years.
4. Understand the necessary and fundamental changes required: Are you ready and willing to
change the way you manage? Are the other managers ready and willing?
5. Recognize the need to re-educate employees: How will you retrain managers and employees to
carry out the changes you described in item 4?
6. Provide incentive systems for the new environment: The carrot-and-stick approach does work.
35.6 Summary
Enterprise computing views an organization as a whole and not just as its separate parts. Four
concepts--IT investment portfolio, IT infrastructure, business logic, and information architecture--are
necessary elements for success in enterprise computing. The new IT infrastructure is more complex and
complicated than ever. Choosing the right technology demands an understanding of where the company is
now and where it wants to go. The core structure of the business should decide the type of software and
its location in the enterprise computing system.
Industrial networks link suppliers with manufacturers from the beginning of the process to the
conclusion of the transaction. Information is passed on all along the way to gain efficiencies and cut costs.
Industrial networks may require a sea-change in the way a company functions. Managers must be ready
and willing to accommodate the changes.

UNIT VI
Lesson 36 Enterprise Resource Planning (ERP)
Learning Objectives
• To describe how integration works in an ERP system using information systems and database
integration.
• To develop the ability to apply the principles of information systems, database integration
and applications within ERP in the design and implementation of enterprise resource
planning systems.
36.1 Introduction
Manufacturing used to be a much simpler process than the convoluted mixture of hardware and
software choices that confront manufacturers today. Once upon a time craftsmen built things for local
customers, with quality and price being the primary concerns of the buyer. As more products became
available, convenience was added to the mix. If a local craftsman had good quality and a reasonable price,
that person usually got the job over someone far away who might have a better price.
Increased mobility changed the situation somewhat, but the differentials had to be high to warrant
traveling any significant distance for a commodity product. Given a unique product, available in limited
locations, a buyer might justify a long trip or high shipping costs.
The traveling peddler attempted to circumvent this logic by bringing the products to the
consumer, but often had to battle the image of a fly-by-night competitor. Buyers wanted to be able to call
on the maker in case of trouble.
Being aware of unusual products wasn't easy in the days before advertising. A person might see a
product carried by a foreigner and inquire as to its origins but not have the resources to contact the maker
and order a similar product. Due to the time necessary to move information, an order could take years to
be fulfilled. The "supply chain" began with obtaining an address for the manufacturer, sending a letter of
order and waiting for a response.
Nowadays, speed of information flow has made manufacturing a global, not a regional or local
business. Coupled with advertising, the ability to move information at the speed of light has opened up all
corners of the globe to makers of all products.
When a Japanese company develops a new "virtual" pet toy, children in Europe and the United
States clamor for it before the tooling is delivered. Internet sites that have replaced EDI as a medium for
processing orders light up with traffic. Television news features these giga-pets, talk show hosts make fun
of them, educators belittle them and kids grow tired of them in record time. The pet rock of the '90s
comes and goes within months.
Blame it on information. The computer has, in the words of one prophet, made making mistakes
so much easier and faster, what did we do without them? It has also allowed small companies to become
giants in their industries by giving them the greatest equalizer since the Colt pistol arrived in the Old
West. Where only the upper reaches of the Fortune 500 could afford computing power in the 1950s and

1960s, starving students have equal power on their desks in the 1990s. Mid-sized companies have access
to the same quality of information as General Motors. The question is no longer, where can I get the
information I need? The question is now, what do I do with all the information I have?
The Answer Is... ERP
We would argue that the answer is much more complex than the question. Information must first
be defined, separate from the delivery mechanism, data. Data does nothing but fill computer drives until it
is presented in an intelligent form to people. Then it becomes information.
There are many computer programs designed to convert data into information, usually for a
specific purpose or function. Shop floor workers need one level of information, in real-time, about the
process or production; executives need a different view of that data for long-range planning and short-
term deployment. Same data, different information.
In many situations, data are available but uncollected. This could require manual entry, bar code
scanning or sensor monitoring to correct. In other cases, the data are collected but stored awaiting a
request. Data mining and data warehousing applications involve this aspect of information development.
Databases are becoming larger and larger as companies find more and more data to store. But all those
bytes are still just data.
Answering that call, software developers have looked for ways to bring many divergent
requirements under a single, if huge, umbrella program called enterprise resource planning or ERP. What
ERP strives to do is combine the needed functions of every application a company requires to do its job
and integrate them all together.
ERP is a hot trend in manufacturing/information technology circles right now, and all indications
point to it getting even hotter. Advanced Manufacturing Research (AMR) estimates that the worldwide
ERP software market grew from $7.2 billion in 1996 to $9.6 billion in 1997. "Much of ERP's market
growth is driven by an increasingly global business focus," observes Gisela Wilson, AMR's director of
primary research. "Manufacturers are scrambling to replace MRPII systems with software that will ease
the integration of business processes and support multi-national and multi-site business environments."
In modern manufacturing operations, information starts at the top and the bottom simultaneously.
Data originates at the machines, the process and the workers. It is collected by sensors, controls and
operators. It indicates what is being made, how and where, when it will be done, and why it won't be on
time. Programs such as manufacturing execution systems (MES) and shop floor control take the data and
create the information, passing it up the chain to the planners and product developers. Here the data are
integrated with other bytes from advanced scheduling and planning systems to produce a report and
forecast.
ERP also can make a difference at the shipping and distribution end of a company. According to
Ashley Mills of the British controls company Eurotherm, which also has implemented a DataWorks
solution, "Our ERP system has cut out duplications, delays and mistakes on delivery times, and
manufacturing has become more flexible. Shipments can go direct, and are therefore smaller and cheaper.
In addition, there's no need to stock materials or finished units, so stocks don't become obsolete and have
to be written off."

36.2 What is ERP?
Enterprise resource planning software, or ERP, doesn't live up to its acronym. Forget about
planning—it doesn't do much of that—and forget about resource, a throwaway term. But remember the
enterprise part. This is ERP's true ambition. It attempts to integrate all departments and functions across a
company onto a single computer system that can serve all those different departments' particular needs.
That is a tall order, building a single software program that serves the needs of people in finance
as well as it does the people in human resources and in the warehouse. Each of those departments
typically has its own computer system optimized for the particular ways that the department does its
work. But ERP combines them all together into a single, integrated software program that runs off a
single database so that the various departments can more easily share information and communicate with
each other. That integrated approach can have a tremendous payback if companies install the software
correctly.
Take a customer order, for example. Typically, when a customer places an order, that order
begins a mostly paper-based journey from in-basket to in-basket around the company, often being keyed
and rekeyed into different departments' computer systems along the way. All that lounging around in in-
baskets causes delays and lost orders, and all the keying into different computer systems invites errors.
Meanwhile, no one in the company truly knows what the status of the order is at any given point because
there is no way for the finance department, for example, to get into the warehouse's computer system to
see whether the item has been shipped. "You'll have to call the warehouse" is the familiar refrain heard by
frustrated customers.
ERP vanquishes the old standalone computer systems in finance, HR, manufacturing and the
warehouse, and replaces them with a single unified software program divided into software modules that
roughly approximate the old standalone systems. Finance, manufacturing and the warehouse all still get
their own software, except now the software is linked together so that someone in finance can look into
the warehouse software to see if an order has been shipped. Most vendors' ERP software is flexible
enough that you can install some modules without buying the whole package. Many companies, for
example, will just install an ERP finance or HR module and leave the rest of the functions for another
day.
36.3 How can ERP improve a company's business performance?
ERP's best hope for demonstrating value is as a sort of battering ram for improving the way your
company takes a customer order and processes it into an invoice and revenue—otherwise known as the
order fulfillment process. That is why ERP is often referred to as back-office software. It doesn't handle
the up-front selling process (although most ERP vendors have recently developed CRM software to do
this); rather, ERP takes a customer order and provides a software road map for automating the different
steps along the path to fulfilling it. When a customer service representative enters a customer order into
an ERP system, he has all the information necessary to complete the order (the customer's credit rating
and order history from the finance module, the company's inventory levels from the warehouse module
and the shipping dock's trucking schedule from the logistics module, for example).
People in these different departments all see the same information and can update it. When one
department finishes with the order it is automatically routed via the ERP system to the next department.
To find out where the order is at any point, you need only log in to the ERP system and track it down.
With luck, the order process moves like a bolt of lightning through the organization, and customers get

their orders faster and with fewer errors than before. ERP can apply that same magic to the other major
business processes, such as employee benefits or financial reporting.
That, at least, is the dream of ERP. The reality is much harsher.
Let's go back to those inboxes for a minute. That process may not have been efficient, but it was
simple. Finance did its job, the warehouse did its job, and if anything went wrong outside of the
department's walls, it was somebody else's problem. Not anymore. With ERP, the customer service
representatives are no longer just typists entering someone's name into a computer and hitting the return
key. The ERP screen makes them businesspeople. It flickers with the customer's credit rating from the
finance department and the product inventory levels from the warehouse. Will the customer pay on time?
Will we be able to ship the order on time? These are decisions that customer service representatives have
never had to make before, and the answers affect the customer and every other department in the
company. But it's not just the customer service representatives who have to wake up. People in the
warehouse who used to keep inventory in their heads or on scraps of paper now need to put that
information online. If they don't, customer service reps will see low inventory levels on their screens and
tell customers that their requested item is not in stock. Accountability, responsibility and communication
have never been tested like this before.
People don't like to change, and ERP asks them to change how they do their jobs. That is why the
value of ERP is so hard to pin down. The software is less important than the changes companies make in
the ways they do business. If you use ERP to improve the ways your people take orders, manufacture
goods, ship them and bill for them, you will see value from the software. If you simply install the
software without changing the ways people do their jobs, you may not see any value at all—indeed, the
new software could slow you down by simply replacing the old software that everyone knew with new
software that no one does.
36.4 How long will an ERP project take?
Companies that install ERP do not have an easy time of it. Don't be fooled when ERP vendors tell
you about a three or six month average implementation time. Those short (that's right, six months is short)
implementations all have a catch of one kind or another: The company was small, or the implementation
was limited to a small area of the company, or the company used only the financial pieces of the ERP
system (in which case the ERP system is nothing more than a very expensive accounting system). To do
ERP right, the ways you do business will need to change and the ways people do their jobs will need to
change too. And that kind of change doesn't come without pain. Unless, of course, your ways of doing
business are working extremely well (orders all shipped on time, productivity higher than all your
competitors, customers completely satisfied), in which case there is no reason to even consider ERP.
The important thing is not to focus on how long it will take—real transformational ERP efforts
usually run between one and three years, on average—but rather to understand why you need it and how
you will use it to improve your business.
36.5 What will ERP fix in my business?
There are five major reasons why companies undertake ERP.

Integrate financial information—As the CEO tries to understand the company's overall performance, he
may find many different versions of the truth. Finance has its own set of revenue numbers, sales has
another version, and the different business units may each have their own version of how much they

contributed to revenues. ERP creates a single version of the truth that cannot be questioned because
everyone is using the same system.
• Integrate customer order information—ERP systems can become the place where the
customer order lives from the time a customer service representative receives it until the loading
dock ships the merchandise and finance sends an invoice. By having this information in one
software system, rather than scattered among many different systems that can't communicate with
one another, companies can keep track of orders more easily, and coordinate manufacturing,
inventory and shipping among many different locations at the same time.
• Standardize and speed up manufacturing processes—Manufacturing companies—especially
those with an appetite for mergers and acquisitions—often find that multiple business units across
the company make the same widget using different methods and computer systems. ERP systems
come with standard methods for automating some of the steps of a manufacturing process.
Standardizing those processes and using a single, integrated computer system can save time,
increase productivity and reduce head count.
• Reduce inventory—ERP helps the manufacturing process flow more smoothly, and it improves
visibility of the order fulfillment process inside the company. That can lead to reduced
inventories of the stuff used to make products (work-in-progress inventory), and it can help users
better plan deliveries to customers, reducing the finished good inventory at the warehouses and
shipping docks. To really improve the flow of your supply chain, you need supply chain software,
but ERP helps too.
• Standardize HR information—Especially in companies with multiple business units, HR may
not have a unified, simple method for tracking employees' time and communicating with them
about benefits and services. ERP can fix that. In the race to fix these problems, companies often
lose sight of the fact that ERP packages are nothing more than generic representations of the ways
a typical company does business. While most packages are exhaustively comprehensive, each
industry has its quirks that make it unique. Most ERP systems were designed to be used by
discrete manufacturing companies (that make physical things that can be counted), which
immediately left all the process manufacturers (oil, chemical and utility companies that measure
their products by flow rather than individual units) out in the cold. Each of these industries has
struggled with the different ERP vendors to modify core ERP programs to their needs.
36.6 Will ERP fit the ways I do business?
It's critical for companies to figure out if their ways of doing business will fit within a standard
ERP package before the checks are signed and the implementation begins. The most common reason that
companies walk away from multimillion-dollar ERP projects is that they discover the software does not
support one of their important business processes. At that point there are two things they can do: They can
change the business process to accommodate the software, which will mean deep changes in long-
established ways of doing business (that often provide competitive advantage) and shake up important
people's roles and responsibilities (something that few companies have the stomach for). Or they can
modify the software to fit the process, which will slow down the project, introduce dangerous bugs into
the system and make upgrading the software to the ERP vendor's next release excruciatingly difficult
because the customizations will need to be torn apart and rewritten to fit with the new version.
Needless to say, the move to ERP is a project of breathtaking scope, and the price tags on the
front end are enough to make the most placid CFO a little twitchy. In addition to budgeting for software
costs, financial executives should plan to write checks to cover consulting, process rework, integration
testing and a long laundry list of other expenses before the benefits of ERP start to manifest themselves.
Underestimating the price of teaching users their new job processes can lead to a rude shock down the

line, and so can failure to consider data warehouse integration requirements and the cost of extra software
to duplicate the old report formats. A few oversights in the budgeting and planning stage can send ERP
costs spiraling out of control faster than oversights in planning almost any other information system
undertaking.
36.7 What does ERP really cost?
Meta Group recently did a study looking at the total cost of ownership (TCO) of ERP, including
hardware, software, professional services and internal staff costs. The TCO numbers include getting the
software installed and the two years afterward, which is when the real costs of maintaining, upgrading and
optimizing the system for your business are felt. Among the 63 companies surveyed—including small,
medium and large companies in a range of industries—the average TCO was $15 million (the highest was
$300 million and lowest was $400,000). While it's hard to draw a solid number from that kind of range of
companies and ERP efforts, Meta came up with one statistic that proves that ERP is expensive no matter
what kind of company is using it. The TCO for a "heads-down" user over that period was a staggering
$53,320.
When will I get payback from ERP—and how much will it be?
Don't expect to revolutionize your business with ERP. It is a navel-gazing exercise that focuses
on optimizing the way things are done internally rather than with customers, suppliers or partners. Yet the
navel gazing has a pretty good payback if you're willing to wait for it—a Meta Group study of 63
companies found that it took eight months after the new system was in (31 months total) to see any
benefits. But the median annual savings from the new ERP system were $1.6 million.
What are the hidden costs of ERP?
Although different companies will find different land mines in the budgeting process, those who have
implemented ERP packages agree that certain costs are more commonly overlooked or underestimated
than others. Armed with insights from across the business, ERP pros vote the following areas as most
likely to result in budget overrun.
1. Training
Training is the near-unanimous choice of experienced ERP implementers as the most

underestimated budget item. Training expenses are high because workers almost invariably have
to learn a new set of processes, not just a new software interface. Worse, outside training
companies may not be able to help you. They are focused on telling people how to use software,
not on educating people about the particular ways you do business. Prepare to develop a
curriculum yourself that identifies and explains the different business processes that will be
affected by the ERP system.
One enterprising CIO hired staff from a local business school to help him develop and teach the
ERP business-training course to employees. Remember that with ERP, finance people will be
using the same software as warehouse people and they will both be entering information that
affects the other. To do this accurately, they have to have a much broader understanding of how
others in the company do their jobs than they did before ERP came along. Ultimately, it will be
up to your IT and businesspeople to provide that training. So take whatever you have budgeted
for ERP training and double or triple it up front. It will be the best ERP investment you ever
make.

2. Integration and testing
Testing the links between ERP packages and other corporate software links that have to be built
on a case-by-case basis is another often-underestimated cost. A typical manufacturing company
may have add-on applications from the major—e-commerce and supply chain—to the minor—
sales tax computation and bar coding. All require integration links to ERP. If you can buy add-
ons from the ERP vendor that are pre-integrated, you're better off. If you need to build the links
yourself, expect things to get ugly. As with training, testing ERP integration has to be done from
a process-oriented perspective. Veterans recommend that instead of plugging in dummy data and
moving it from one application to the next, run a real purchase order through the system, from
order entry through shipping and receipt of payment—the whole order-to-cash banana—
preferably with the participation of the employees who will eventually do those jobs.
3. Customization
Add-ons are only the beginning of the integration costs of ERP. Much more costly, and
something to be avoided if at all possible, is actual customization of the core ERP software itself.
This happens when the ERP software can't handle one of your business processes and you decide
to mess with the software to make it do what you want. You're playing with fire. The
customizations can affect every module of the ERP system because they are all so tightly linked
together. Upgrading the ERP package—no walk in the park under the best of circumstances—
becomes a nightmare because you'll have to do the customization all over again in the new
version. Maybe it will work, maybe it won't. No matter what, the vendor will not be there to
support you. You will have to hire extra staffers to do the customization work, and keep them on
for good to maintain it.
4. Data conversion
It costs money to move corporate information, such as customer and supplier records, product
design data and the like, from old systems to new ERP homes. Although few CIOs will admit it,
most data in most legacy systems is of little use. Companies often deny their data is dirty until
they actually have to move it to the new client/server setups that popular ERP packages require.
Consequently, those companies are more likely to underestimate the cost of the move. But even
clean data may demand some overhaul to match process modifications necessitated—or
inspired—by the ERP implementation.
5. Data analysis
Often, the data from the ERP system must be combined with data from external systems for
analysis purposes. Users with heavy analysis needs should include the cost of a data warehouse in
the ERP budget—and they should expect to do quite a bit of work to make it run smoothly. Users
are in a pickle here: Refreshing all the ERP data every day in a big corporate data warehouse is
difficult, and ERP systems do a poor job of indicating which information has changed from day
to day, making selective warehouse updates tough. One expensive solution is custom
programming. The upshot is that the wise will check all their data analysis needs before signing
off on the budget.
6. Consultants ad infinitum

When users fail to plan for disengagement, consulting fees run wild. To avoid this, companies
should identify objectives for which its consulting partners must aim when training internal staff.
Include metrics in the consultants' contract; for example, a specific number of the user company's
staff should be able to pass a project-management leadership test—similar to what Big Five
consultants have to pass to lead an ERP engagement.
7. Replacing your best and brightest
It is accepted wisdom that ERP success depends on staffing the project with the best and brightest
from the business and IS divisions. The software is too complex and the business changes too
dramatic to trust the project to just anyone. The bad news is a company must be prepared to
replace many of those people when the project is over. Though the ERP market is not as hot as it
once was, consultancies and other companies that have lost their best people will be hounding
yours with higher salaries and bonus offers than you can afford—or that your HR policies permit.
Huddle with HR early on to develop a retention bonus program and create new salary strata for
ERP veterans. If you let them go, you'll wind up hiring them—or someone like them—back as
consultants for twice what you paid them in salaries.
8. Implementation teams can never stop
Most companies intend to treat their ERP implementation as they would any other software
project. Once the software is installed, they figure the team will be scuttled and everyone will go
back to his or her day job. But after ERP, you can't go home again. The implementers are too
valuable. Because they have worked intimately with ERP, they know more about the sales
process than the salespeople and more about the manufacturing process than the manufacturing
people. Companies can't afford to send their project people back into the business because there's
so much to do after the ERP software is installed. Just writing reports to pull information out of
the new ERP system will keep the project team busy for a year at least. And it is in analysis—
and, one hopes, insight—that companies make their money back on an ERP implementation.
Unfortunately, few IS departments plan for the frenzy of post-ERP installation activity, and fewer
still build it into their budgets when they start their ERP projects. Many are forced to beg for
more money and staff immediately after the go-live date, long before the ERP project has
demonstrated any benefit.
9. Waiting for ROI
One of the most misleading legacies of traditional software project management is that the
company expects to gain value from the application as soon as it is installed, while the project
team expects a break and maybe a pat on the back. Neither expectation applies to ERP. Most of
the systems don't reveal their value until after companies have had them running for some time
and can concentrate on making improvements in the business processes that are affected by the
system. And the project team is not going to be rewarded until their efforts pay off.
10. Post-ERP depression
ERP systems often wreak cause havoc in the companies that install them. In a recent Deloitte
Consulting survey of 64 Fortune 500 companies, one in four admitted that they suffered a drop in
performance when their ERP system went live. The true percentage is undoubtedly much higher.
The most common reason for the performance problems is that everything looks and works

differently from the way it did before. When people can't do their jobs in the familiar way and
haven't yet mastered the new way, they panic, and the business goes into spasms.
36.8 Why do ERP projects fail so often?
At its simplest level, ERP is a set of best practices for performing different duties in your
company, including finance, manufacturing and the warehouse. To get the most from the software, you
have to get people inside your company to adopt the work methods outlined in the software. If the people
in the different departments that will use ERP don't agree that the work methods embedded in the
software are better than the ones they currently use, they will resist using the software or will want IT to
change the software to match the ways they currently do things. This is where ERP projects break down.
Political fights break out over how—or even whether—the software will be installed. IT gets bogged
down in long, expensive customization efforts to modify the ERP software to fit with powerful business
barons' wishes. Customizations make the software more unstable and harder to maintain when it finally
does come to life. The horror stories you hear in the press about ERP can usually be traced to the changes
the company made in the core ERP software to fit its own work methods. Because ERP covers so much
of what a business does, a failure in the software can bring a company to a halt, literally.
But IT can fix the bugs pretty quickly in most cases, and besides, few big companies can avoid
customizing ERP in some fashion—every business is different and is bound to have unique work methods
that a vendor cannot account for when developing its software. The mistake companies make is assuming
that changing people's habits will be easier than customizing the software. It's not. Getting people inside
your company to use the software to improve the ways they do their jobs is by far the harder challenge. If
your company is resistant to change, then your ERP project is more likely to fail.
How do companies organize their ERP projects?
Based on our observations, there are three commonly used ways of installing ERP.
• The Big Bang—In this, the most ambitious and difficult of approaches to ERP implementation,
companies cast off all their legacy systems at once and install a single ERP system across the
entire company. Though this method dominated early ERP implementations, few companies dare
to attempt it anymore because it calls for the entire company to mobilize and change at once.
Most of the ERP implementation horror stories from the late '90s warn us about companies that
used this strategy.Getting everyone to cooperate and accept a new software system at the same
time is a tremendous effort, largely because the new system will not have any advocates. No one
within the company has any experience using it, so no one is sure whether it will work. Also,
ERP inevitably involves compromises. Many departments have computer systems that have been
honed to match the ways they work. In most cases, ERP offers neither the range of functionality
nor the comfort of familiarity that a custom legacy system can offer. In many cases, the speed of
the new system may suffer because it is serving the entire company rather than a single
department. ERP implementation requires a direct mandate from the CEO.
• Franchising strategy—This approach suits large or diverse companies that do not share many
common processes across business units. Independent ERP systems are installed in each unit,
while linking common processes, such as financial bookkeeping, across the enterprise. This has
emerged as the most common way of implementing ERP. In most cases, the business units each
have their own "instances" of ERP—that is, a separate system and database. The systems link
together only to share the information necessary for the corporation to get a performance big
picture across all the business units (business unit revenues, for example), or for processes that
don't vary much from business unit to business unit (perhaps HR benefits). Usually, these

implementations begin with a demonstration or pilot installation in a particularly open-minded

and patient business unit where the core business of the corporation will not be disrupted if
something goes wrong. Once the project team gets the system up and running and works out all
the bugs, the team begins selling other units on ERP, using the first implementation as a kind of
in-house customer reference. Plan for this strategy to take a long time.
• Slam dunk—ERP dictates the process design in this method, where the focus is on just a few key
processes, such as those contained in an ERP system's financial module. The slam dunk is
generally for smaller companies expecting to grow into ERP. The goal here is to get ERP up and
running quickly and to ditch the fancy reengineering in favor of the ERP system's "canned"
processes. Few companies that have approached ERP this way can claim much payback from the
new system. Most use it as an infrastructure to support more diligent installation efforts down the
road. Yet many discover that a slammed-in ERP system is little better than a legacy system
because it doesn't force employees to change any of their old habits. In fact, doing the hard work
of process reengineering after the system is in can be more challenging than if there had been no
system at all because at that point few people in the company will have felt much benefit.
36.9 Summary
We have become accustomed to more of everything at every stage of our lives, and we get testy
when systems don't produce. Fifteen years ago, microprocessor speed was measured in single digits (the
8088 in the original IBM PC clocked in at 5 MHz); today, 200 MHz is comparable to a compact car on
the Autobahn -- nice, but not fast enough to keep up with traffic. MIPS have been replaced by GigaFlops
as a test of value. Faster means more, more means better and better means whipping the competition. To
handle the capabilities of the hardware, we insist that the fastest, best-mannered software be available at
every level of the company. The data must flow to where it is needed, immediately.
Again, we are seeing the difference between data and information. Data flows throughout the
ERP system, entered once and available everywhere. But until it is needed, it is not information. Once it is
called for, the application creates information from the data and presents it in the best possible manner for
the user Ð operator, executive, order taker, maintenance worker, systems analyst or whomever -- or the
equipment -- machine, control, monitor, sensor, computer, EDI system or whatever.
We are now seeing the advantages of using this concept of data flowing to produce additional
productivity in other areas through the use of the technique called work flow. Logically, work flow can be
embedded in data flow so the computer can determine the best flow of both. The computer augments the
system designer by allowing immediate simulation of work flows to prove -- or disprove -- the concepts.
Work flow and demand flow work together, one from the inside out, the other from the outside in.
ERP is not confined within the walls of a single entity. Its data flows go out to suppliers and
vendors, customers and prospects. Information is presented on Internet sites and transferred to other
computers on a network at the speed of light, or around the world via cable and radio beams bounced off
satellites. Nothing equals the computer for making the world a much smaller place. What you find out can
be shared with another person or even millions of people at the same time you learn it yourself. Design
and product development can be a collaborative process without barriers of space and time. Groupware,
data management and communications combine to allow everyone to sit in the same office, regardless of
where they are physically located.

UNIT VI
Lesson 37 - Ethical and Social Impact of Information Systems
Learning Objectives
1. To know the social and ethical issues related to information systems
2. To study about the ethical princples in Information System Management
3. To knowthe moral dimensions of Information Systems
37.1 Introduction
If notheing else , history has shown that technology change is inevitable. Competitive economics
virtually guarantees that the search for new products, new manufacturing techniques, and other ways to
gain competitive advantage will continue.
Changes in technology often affect sociey. Technology can change individuals, jobs, education,
governments, and social interactions. As components of society, each group has rights ans responsibilities
to others, such as a right to privacy and obligations regarding ethics.
Technology’s efect on individuals can be benficial or detrimental. Often a change in technology
helps one set of individuals and harms another group. Typical problems include loss of privacy,
depersonalisation, and changing incentives or motivations. Advantages include lower prices and better
products and services.
We have to undersatnbd one fact that Informatioin Systems become ubiquitous. People as well as
organisations have come to depend on them not only for success and survival, but also for the conduct of
everyday transactions and activities. Computer systems have invaded nearly every aspet of our daily
lives. As information technology advances, it creates a continuing sream of new issues pertaining to those
parts of our lives that it impacts. In the business arena, information technology has presented ethical
issues in four areas: privacy, property, accuracy and access. In addition, ethical issues sorround the impact
information technology has on us all.
37.2 Understanding Ethical & Social Issues Related To Systems
It probably goes without saying that the security and ethical issues raised by the Information Age
and specifically the Internet are the most explosive to face our society in decades. It will be many years
and many court battles before socially acceptable policies and practices are in place.
You may love the idea that a gardening Web site or a mail order catalog gives you information
about what grows best in your backyard (literally your backyard). You might even love the idea that you
can sign on to Amazon.com and there's information about a book or CD by your favorite author or artist.
If you're not especially interested in Stephen King or Frank Sinatra, don't worry; Amazon.com knows that
and so won't bother you with products from those artists.
A Model for Thinking about Ethical, Social, and Political Issues
Many of these issues not only touch our society as a whole, but also raise lots of questions for
organizations, companies, and the workplace in general. We hear arguments for free speech, personal
responsibility, and corporate responsibility. There are discussions about the government's role in all this.
How you act, individually and as groups, in this gray area may well define the future of our
society. Though that may sound a bit dramatic, you must understand that you are part of the development
of "acceptable usage" of this new medium and will help define the direction in which it goes. That's no

exaggeration: You use the Internet frequently (and be assured the frequency will increase), therefore you
are...!
Five Moral Dimensions of the Information Age
FIGURE 5.1
Ethical, moral, political issues in an information society
This above figure shows the relationship between ethical, social, and political issues in an
information society. You could change this diagram somewhat to avoid the impression that the five
dimensions are separate. You'd show significant overlap of each area, and most of the diagram would be
in shades of gray. The five dimensions we'll discuss are: information rights and obligations, property
rights, accountability and control, system quality, and the quality of life.
Key Technology Trends That Raise Ethical Issues
Information technologies pose problems and threats to established societal rules, and new
advances pose new situations and possible threats to privacy and ethics. In addition to the technologies in
the book, you need to understand the most recent technological threats to your privacy in cyberspace:
You say to yourself, "Hey I don't really care. Nobody will ever care about what I do or where I go
on the Internet." Well, you might want to think twice about that. There have been reported instances of
companies accessing databases from various sources as part of the screening process to determine what

chat rooms, Web sites, etc., prospective employees have visited. How can that be, you ask? The
technological trends we discuss, such as advances in data storage, will give you one clue. The scenario at
the beginning of this section about a personal profile is possible through the technique called datamining.
It can and has been done, so you should be concerned and you should care.
37.3 Ethics in an Information Society
Did you ever hear the old warning, "Just because you can, doesn't mean you should?" Well, a lot
of things are possible on the Internet nowadays, but that doesn't mean you should do them.
Ethics is easily managed in small groups because the group itself tends to control the individual's
behavior. The larger the group, the harder it is to manage the actions of individuals. Now stretch that to a
huge number of people with many frames of reference and experiences. Responsibility to the group
becomes harder to police and accountability for an individual's actions is harder to enforce.
Basic Concepts: Responsibility, Accountability, and Liability
Every action causes a reaction. When you're using the Internet, computers on campus, or your
employer's computer, you should be aware of:
• Responsibility: accepting potential costs, duties, and obligations for your decisions.
• Accountability: determining who should take responsibility for decisions and actions.
• Liability: legally placing responsibility with a person or group.
• Due Process: ensuring the laws are applied fairly and correctly.
Responsibility, accountability, and liability are all yours when it comes to your actions in
cyberspace. Every Internet Service Provider has a "usage policy," even the so-called anonymous emailers
that hide your real identity. HotMail is a popular Internet email service that allows you to mask who you
really are. You could send out all the, shall we say, unethical, threatening, nasty, aberrant email you like.
You think: "Hey, no one will really know who I am. This is cool."
And then here comes the message from HotMail to cease and desist. Your free email account is
cancelled because you violated HotMail's usage policy. Then your local Internet Service Provider
contacts you and tells you you're terminated, baby! You violated its usage policy by your actions. By now
you're really mad, not to mention embarrassed (at least we hope so). It's true. It happens.
Just because you think you can, doesn't mean you should. Would you stand in the middle of
campus and shout insults? As the text points out, "Using information technology in a socially responsible
manner means that you can and will be held accountable for the consequences of your actions." Just as
you are subject to rules, whether you like them or not, in public, you are subject to societal rules in
cyberspace. Anonymity isn't a license for socially unacceptable behavior.
Some people seem to absolve themselves of responsibility by putting the blame on the computer -
"Hey, the computer screwed up," or "Since it was an anonymous username, I didn't think I'd get caught."
It just doesn't work that way. No one can hide behind the technology. Humans control the computers, not
the other way around.

And if you have received threatening, aberrant emails or flames in chatroom or discussion
groups, and haven't reported them according to the usage policies, you may be as much a part of the
problem as the perpetrator!
Ethical Analysis
It's safe to say you'll find yourself in situations where your ethics are challenged. What should
you do? Try:
• Separating fact from fiction.

• Remembering, no matter how thin you slice it, there are always two sides.
• Determining who's really involved.
• Compromising; it doesn't always have to be an "either-or" outcome.
• Anticipating the outcome; it will help you devise better solutions.
We'll be incorporating the ethical principles outlined in the text into the discussions throughout
the remainder of this chapter.
Candidate Ethical Principles
The principles listed in the lesson are deeply rooted in cultures around the world. We seriously
doubt the authors had the Internet in mind when they developed these guidelines. But, when you think
about it, the principles work nicely, even in cyberspace!
Professional Codes of Conduct
Codes of conduct were created in part to give the public a sense of trust in a group of
professionals. Professionals use the codes to define the limits of their activities and to help guide them in
their businesses and organizations.
Some Real-World Ethical Dilemmas
Individuals, companies, and corporations are being forced to deal with these new ethical and
social issues in ways never before imagined. Apply the ethical analysis we just discussed to the real-world
situations presented here and in the lesson.
No issue has been harder for organizations to deal with than that of email. Should companies be
allowed to read employees' emails, especially if they are personal? Should employees be allowed to send
personal emails to begin with? Should emails be used against a person or company in a court of law, and
how? A recent example of this issue is the Microsoft antitrust trial.
So in your opinion, what is right? Is it okay for an employee to download the latest picture from
Restricted Web site and use it as a screensaver on a computer at work? Is it okay to run a personal
commercial Web site from your workplace computer using the company's computer resources? Is it okay
to email discriminatory jokes over the company network that wouldn't be allowed over the water cooler?
Is it okay to send email telling everyone that the boss is a jerk, then get mad when the company fires you?
Is it okay for the company to use the new Intel Pentium III chip to monitor your computer usage
every minute you're on the job? Is it okay for the company to use technology to monitor your keystrokes

so they can determine how much work you're doing? Is it okay for you to use the company's computers
and networks to surf Macy's Web site and order the latest fashions during your lunch break? Should a
company be allowed to remove Solitaire from employee computers?
37.4 The Moral Dimensions of Information Systems
This section examines the five moral dimensions (information rights, property rights,
accountability, liability, and control, system quality, and the quality of life) by asking you to examine
them from a personal standpoint.
Information Rights: Privacy and Freedom in an Information Society
There have been some attempts to regulate the collection and use of information about
individuals, as the table shows.
Many of us take our privacy and freedom for granted. You should be aware of how technology is
changing and challenging our basic assumptions about these issues. Video rental records are more
protected from misuse and prying than are your medical records. It's a fact.
We all assume that the Constitution guarantees by our personal privacy and freedom from
surveillance. If someone set up a video camera inside your dorm room or on your front porch to monitor
your every movement, what would you do? In some cases, that's similar to what happens when you access
some Web sites. So how do we protect our privacy and freedom from surveillance in a high-tech world?
The lesson provides some information regarding privacy rights protected by law and established
practices. But before you jump up and say, "Hey, the Privacy Act of 1974 says you can't spy on me,"
remember that law applies only to the federal government's actions. If Macy's or Playboy or Buy.com
wants to collect information about your surfing habits and sell it to other companies, there is nothing to
stop them. Absolutely nothing!
Think about this: If information is supposedly collected for one purpose, is it ethical for that
information to be used for a totally different purpose without you knowing it? Is it fair to require you to
provide medical information that is primarily intended to be used to pay your insurance bills and then
have that same information used against you when the insurance company deems you too expensive and
cancels your policy? Is it fair to have that same information used against you in denying you employment
because you're too expensive to hire?

Spamming (unsolicited emails) has been challenged in the courts by Internet Service Providers
(ISP) as an unfair practice. The ISPs say the thousands of emails clog their systems and no one wants
them anyway. The spammers argue their right to Freedom of Speech is violated if they can't send emails
to anyone they want. Which side are you on?
Property Rights: Intellectual Property
Intellectual property issues have been around for hundreds of years. Some of the laws and
policies in place to settle disputes about copyrights, patents, and trade secrets have to be rewritten to
apply to the Internet. Intellectual property is a result of someone's effort to create a product of value based
on their experiences, knowledge, and education. In short, intellectual property is brain power.
What if you wrote the next great American novel, hoping to cash in big time? Maybe you could
retire to the Bahamas and drink lemonade on the beach all day. But then you find out that someone posted
your next great American novel to the Internet and everyone is reading it free of charge. Now you're back
in your hometown drinking lemonade at the local mall while you decide whether to look for a job at
MacDonald's or Burger King. The good news is everyone loves your book!
Unfortunately, that sort of thing happens too often in cyberworld. You're pretty excited to get that
free copy of the newest game software while the poor guy who spent hours of his time and effort writing
it is not so excited to realize he's not getting any compensation.
Everything on the Web is considered to be protected under copyright and intellectual property
laws unless the Web site specifically states that the content is public domain.
Copyright laws and intellectual property rights cannot be violated on the Internet any more than
they can in other mediums. While this isn't a law class, you should be aware of the fine line between
acceptable and legal usage of materials and the illegal theft of materials. When it comes to copyright
material, the underlying ideas are not protected, just the publication of the material. On the other hand, a
patent grants a monopoly on the underlying concepts and ideas. Before you use anything, especially any
material on the World Wide Web, make sure you are using it legally and ethically.
Get past the idea that because everything on the Web is free, easy, and available 24 hours a day, it
must be okay to use it however you want. The question you should be asking yourself is "Is it ethically
right and legal?"
Accountability, Liability, and Control
Many of our laws and court decisions establishing precedents in the area of accountability,
liability, and control were firmly in place long before computers were invented. Many of them date back
to the early 1900s, and some simply don't make sense in this day and age. That's what we were referring
to when we talked about new questions for organizations, companies, and the workplace in general. No
issue makes this subject more important than the Internet laws our government has tried and still tries to
pass.
System Quality: Data Quality and System Errors
As we rely on Information Systems more, data quality issues are gaining importance. These
issues affect you as a consumer and as a user.

When the credit reporting agencies mess up your credit record and you can't get a car loan, whose
fault is it? Yours or the credit agency's? If the Electric Company doesn't get its Y2K bug fixed and you
lose power on January 1, 2000, whose problem is that? What if you're driving down the road, the
computer chip controlling your brake system fails, and you have a rather nasty crash? Who is at fault?
You, the car company, or the company that made the computer chip?
Most of us use software that the manufacturer knows has bugs. Once in a while these bugs will
affect our computer usage. Usually they are nothing more than an aggravation. As more and more
companies do business on the Internet, will Internet Service Providers be held accountable for equipment
outages rendering those businesses unable to process transactions?
Quality of Life: Equity, Access, Boundaries
Invariably, when discussing online technology, some students mention their concern about losing
the face-to-face contact with other human beings. We hear stories about children who haven't developed
normal social skills because they spend all their time in front of a computer. No discussion about the
quality of life issues would be complete without mentioning "on-line love affairs." Of course, many
people lose their jobs and their way of life because of technology. These are all valid concerns.
One quality of life issue that affects more and more people personally is the ability to work from
home. Most telecommuters used to have a "regular day job" 9 to 5, five days a week in a typical office
setting. If they didn't get their work done today, they would wait until they were back in the office
tomorrow or Monday. Now because of technology they can work seven days a week, all hours of the day,
at home. And sometimes they do. The impact on personal and family life can be considerable.
There is an upside to the jobs issue, though. Many parents like telecommuting because they can
stay home with, or at least be nearer, their children. More and more people are leaving the big cities and
moving to small towns for the quality of life, yet they can still keep their well-paying jobs. Many small
companies are able to expand their customer base because of technology, which in turns helps the
employees immensely. Completely new businesses are born because of technology.
Some people think we've reached the limit when they learn that we can now buy groceries online.
After all, when you have everything loaded into the car, trying to find your way around a strange town,
anxious to get on the ski slopes, have three screaming kids in the back seat, and everyone is stressed out
from the travel, the last thing you want to do is hunt down a grocery store. Why not email ahead and have
your food and treats waiting for you when you check into your accommodations? What a terrific idea.
Computer crime is one area that has been extremely hard for our society and our governments to
keep up with. Many laws have to be rewritten and many new laws must be implemented to accommodate
the changes. Computer crime and abuse extends to any wrongdoing involving equipment and Internet
usage. We spoke earlier about anonymity not being a license for socially unacceptable behavior. You
should remember that everything you do on a network or the Internet is recorded and can be tracked.
Many people committing computer crimes and abuse have been caught and prosecuted.
Other issues affecting our society include job losses and career changes caused by technology.
You can argue the positive or negative effects, but one thing is clear: you'll be a part of the evolution of
technology for the rest of your life. You will have to continually update your skills and knowledge in
order to remain competitive in the job market. As companies continue to embrace new technology and
new methods of using it, you'll be responsible for ensuring your skills and education remain current.

Our government recognizes the danger of allowing unequal access to technology to continue. It
has enlisted the help of private individuals and corporations in an effort to install computers and Internet
access in public schools and libraries across the nation. Most schools are now wired for networks and are
learning to incorporate technology into the curriculum.
Health Risks: RSI, CTS, and Techno stress
As managers, you should be acutely aware of the health issues caused by computer usage. Why?
Because these health issues cost businesses huge amounts of dollars each year in medical treatment
claims and lost productivity. Carpal tunnel syndrome (CTS) is the most serious health issue plaguing
businesses. It doesn't take much to avoid the problems associated with computer usage. Ergonomics, the
study of the relationship between humans and machines, has helped determine that it's cheaper to
purchase equipment that reduces the health risks associated with computers such as different keyboards,
monitors that reduce eye strain, and desks that allow proper body positions.
Too much of a good thing can be bad. You've heard of road rage, the anger people experience
when driving. We are now experiencing road rage on the Information Superhighway, where it is called
technostress. Managers should encourage employees to take frequent breaks from their computer and to
recognize and understand the dangers of isolation. We may be a wired nation, but we still need the human
touch.
How has all this technology affected you? Think about it. Ultimately, there is a positive and a
negative side to everything. How you handle it determines how it affects you.
Management Actions: A Corporate Code of Ethics
Many firms have not established a Code of Ethics or a policy for employee conduct when
computing in today's workplace. Some corporations are confused about what to include and how to
approach this new dilemma. Following are the five moral dimensions would be a good start! Businesses
and their managers should recognize:
• The information rights to privacy and freedom

• The property rights to individual ideas and efforts
• The accountability, liability and control issues involved in using technology
• The system quality requirements of businesses and individuals
• The quality of life impact of technology
Companies can no longer ignore the necessity of establishing rules for technology usage. The
issue will only continue to grow. If you work for a company that doesn't have a policy, you should
encourage it to establish one immediately. If you're a manager in a company, you should get busy and
establish a policy for your employees - it's the only fair thing to do.
37.5 Summary
Technological trends are posing new situations and questions we haven't had to deal with before.
Since it's your world and your future, you should be concerned and become involved in their resolution.
Ethics in an information society holds each person responsible for his or her actions. Each person is
accountable for everything he or she does, no matter how anonymous the action may seem. Each person
is liable for the consequences his or her actions may inflict on other people and society as a whole.

If it sounds too good to be true, it is. If it's illegal or immoral or unethical outside the computing
arena, it's probably illegal, and immoral and unethical in the computing arena. If you are aware of a
problem or are a victim of unethical, illegal actions, and you don't do something about it, you're part of
the problem. Managers have an obligation to ensure policies are in place to help guide their employees in
the ethical and legal use of technology. It's your new world - use it wisely.

UNIT VI
Lesson 38 – Challenges in Management of Information Systems
Learning Objectives
1. To know about the various challenges organisation facing in MIS

2. To know the benefits and negative impacts of Information Systems
39.1 Introduction
Although information systems are creating many exciting opportunities for both businesses and
individuals, they are also a source of new problems, issues and challenges for managers. In this course,
you will learn about both the challenges and opportunities information systems pose, and you will be able
to use information technology to enrich your learning experience.
39.2 Learning to Use Information Systems: New Opportunities with Technology
Is this new technology worth the headaches and heartaches associated with all the problems that
can and will arise? Yes. The opportunities for success are endless. The new technologies do offer
solutions to age-old problems. Improvements are possible to the way you operate and do business.
The rest of the lessons in this book and this course will give you tools you can use to be successful
with the current and future Management Information Systems.
The Strategic Business Challenge
Companies spend thousands of dollars on hardware and software, only to find that most of the
technology actually goes unused. "How can that be?" you ask. Usually because they didn't pay attention
to the full integration of the technology into the organization. Merely buying the technology without
exploiting the new opportunities it offers for doing business smarter and better doesn't accomplish much.
Think and rethink everything you do and figure out how you can do it better. Change is inevitable, and
information must be managed just as you would any other resource.
Creating a digital firm and obtaining benefit is a long and difficult journey for most organisations.
Despite heavy information technology investments, many organisations are not realising significant
business value from their business systems, nor or they become digitally enabled. The power of computer
hardware and software has grown much more rapidly than the ability of organisations to apply and to use
this technology. To fully benefit form information technology, realize genuine productivity, and take
advantage of digital firm capabilities, many organisations actually need to be redesigned. They will have
to make fundamental changes in organisational behavior, develop new business models and eliminate the
inefficiencies of outmoded organisational structures. If organisations merely automate what they are
doing today, they are largely missing the potential of information technology.
The Globalization Challenge
The world becomes smaller every day. Competition increases among countries as well as
companies. A good Management Information System meets both domestic and foreign opportunities and
challenges. The rapid growth in international trade and the emergence of a global economy call for

information systems that can support both producing and selling goods in many different countries. In the
past, each regional office of a multinational corporation focused on solving its own unique
information problems. Given language, cultural and political differences among countries, this focus
frequently resulted in chaos and the failure of central management controls. To develop integrated,
multinational, information systems, businesses must develop global hardware, software and
communication standards; create cross-cultural accounting and reporting structures; and design
transnational business processes.
The Information Architecture Challenge
You have to decide what business you are in, what your core competencies are, and what the
organization's goals are. Those decisions drive the technology, instead of the technology driving the rest
of the company. Purchasing new hardware involves more than taking the machine out of the box and
setting it on someone's desk. Remember the triangle of hardware, software, and persware. Take care of
the people and they will take care of the rest! Information architecture describes how to incorporate
technology into the mainstream processes in which the business is involved. How will the new
Information System support getting the product produced and shipped? How will Advertising and
Marketing know when to launch ad campaigns? How will Accounting know when to expect payment?
Many companies are saddled with expensive and unwieldy information technology platforms that
cannot adopt to innovation and change. Their information systems are so complex and brittle that they act
as constraints on business strategy and execution. Meeting new business and technology challenges may
require redesigning the organisation and building a new information architecture and information
technology infrastructure.
The Information Systems Investment Challenge
Too often managers look at their technological investments in terms of the cost of new hardware
or software. They overlook the costs associated with the non-technical side of technology. Is productivity
up or down? What is the cost of lost sales opportunities and lost customer confidence from a poorly
managed E-Business Web site? How do you determine if your Management Information System is worth
it?
A major problem raised by the development of powerful, inexpensive computers involves not
technology but management and organisations. It’s one thing to use information technology to design,
produce, deliver and maintain new products. It’s another thing to make money doing it. How can
organisations obtain a sizeable payoff from their investments in information systems? How can
management make sure that the management information systems contribute to corporate value?
The Responsibility and Control Challenge
Remember, humans should drive the technology, not the other way around. Too often we find it
easier to blame the computer for messing up than to realize it's only doing what a human being told it to
do. Your goal should be to integrate the technology into the world of people. Humans do control the
technology, and as a manager, you shouldn't lose sight of that.
How can we define information systems that people can control and understand? Although
information systems have provided enormous benefits and efficiencies, they have also created new
problems and challenges of which managers should be aware.
The following table describes some of these problems and challenges.

Positive and Negative Impacts of Information Systems
Benefits of Information Systems Negative Impact

Information system can perform calculations or By automating activities that were previously
process paperwork much faster than people. performed by people, information systems may

Information systems provide new efficiencies Information systems are used in so many

computer controlled airplanes and air terminals transportation services, paralyzing
communities.

patient monitoring health problems
The internet distributes information instantly to The internet can be used to distribute illegal
millions of people across the world. copies of software, books, articles, and other
intellectual property.
Management's focus must continually change to take advantage of new opportunities. Changes
should take place throughout the organization. They require lots of attention and planning for smooth
execution.
Extranets pack tough new challenges for MIS - Industry Trend or Event
Asking analysts and consultants to talk about the extranet phenomenon often leads to the same
response: "What do you mean when you say extranet?" Confusion abounds when it comes to trying to
nail down a solid definition for something that to some folks makes more sense as a concept than as a
product or service.
In fact, at least one industry player believes the term to be meaningless. Semantics aside, many
organizations are beginning to see real advantages to allowing selected suppliers, customer and business
partners access to part or all of their own networks via the Internet, according to observers. Within the
next three to four years, "the primary vehicle for delivering electronic commerce in the b-to-b [business to
business] world will in fact be over extranets, rather than private value-added networks or even the global,
open Internet," says Alyse Terhune, a research director with the Gartner Group in Stamford, Conn.
And while companies used to develop and implement their own extranet strategies, more and
more are looking to outside help, according to analysts. Internet Service Providers (ISPs) are particularly
eager to cash in on the growing market.
Outsourcing may be a cheap and easy answer for some firms, but Terhune isn't convinced it's a
surefire strategy. "I think that there are lots of pieces involved in a successful extranet, and some of them
are the core competency of ISPs and some of them aren't." A solid infrastructure is one thing, she says,
but administrative logistics can be something else entirely. Especially when different organizations with
different ways of doing business get together.

"You have to deal with the business process that's being accommodated. That means providing
things like applications that will facilitate say, buying and selling. That's more than just a catalogue. In the
business world that's who within my requisitioning organization can buy from what suppliers," what they
can buy and how much they can buy, she says.
Security can also be a big issue, but is more of an administrative problem than a technological
one, says Terhune. "When you really look at the problem of securing information and determining which
information has to be secured and to whom, it becomes more complicated." Technical solutions such as
encryption, firewalls and data packets are "more or less standard features" these days, Reisman claims,
but some organizations are still very Internet-shy.
Large corporations tend to be bigger targets for hackers and spies, he says, something small firms
might want to consider when budgeting for security features. Future developments are particularly hard to
quantify when it comes to extranets. It's difficult enough to come to a consensus on what they are now, let
alone to guess how they might develop or grow in use over time.
39.3 Summary
Managers will also be faced with ongoing problems of security and control. Information systems
are so essential to business, government and daily life that organisations must take special steps to ensure
that they are accurate, reliable and secure. A firm invites disaster if it uses systems that don’t work as
intended, that don’t deliver information in a form that people can interpret correctly and use, or that have
control rooms, where control don’t work or where instruments give false signals. Information systems
must be designed so that they function as intended and so that humans can control the process.

UNIT VI
Lesson 39 - Tutorial on ERP Packages and Softwares
A Short SAP Tutorial
What is SAP?
SAP is the leading Enterprise Information and Management Package worldwide. Use of this
package makes it possible to track and manage, in real-time, sales, production, finance accounting and
human resources in an enterprise.
What Makes SAP Different?
Traditional computer information systems used by many businesses today have been developed to
accomplish some specific tasks and provide reports and analysis of events that have already taken place.
Examples are accounting general ledger systems. Occasionally, some systems operate in a "real-time"
mode that is, have up to date information in them and can be used to actually control events. A typical
company has many separate systems to manage different processes like production, sales and accounting.
Each of these systems has its own databases and seldom passes information to other systems in a timely
manner.
SAP takes a different approach. There is only one information system in an enterprise, SAP. All
applications access common data. Real events in the business initiate transactions. Accounting is done
automatically by events in sales and production. Sales can see when products can be delivered.
Production schedules are driven by sales. The whole system is designed to be real-time and not historical.
SAP structure embodies what are considered the "best business practices". A company
implementing SAP adapts it operations to it to achieve its efficiencies and power. The process of adapting
procedures to the SAP model involves "Business Process Re-engineering" which is a logical analysis of
the events and relationships that exist in an enterprise's operations.
SAP Application Modules
SAP has several layers. The Basis System is the heart of the data operations and should be not
evident to higher level or managerial users. Other customizing and implementation tools exist also. The
heart of the system from a manager's viewpoint are the application modules. These modules may not all
be implemented in a typical company but they are all related and are listed below :
• FI Financial Accounting—designed for automated management and external reporting of general

ledger, accounts receivable, accounts payable and other sub-ledger accounts with a user defined
chart of accounts. As entries are made relating to sales production and payments journal entries
are automatically posted. This connection means that the "books" are designed to reflect the real
situation.
• CO Controlling—represents the company's flow of cost and revenue . It is a management
instrument for organizational decisions. It too is automatically updated as events occur.
• AM Asset Management—designed to manage and supervise individual aspects of fixed assets
including purchase and sale of assets, depreciation and investment management.

• PS Project System—is designed to support the planning, control and monitoring of long-term,
highly complex projects with defined goals.
• WF Workflow—links the integrated SAP application modules with cross-application
technologies, tools and services
• IS Industry Solutions—combine the SAP application modules and additional industry-specific
functionality. Special techniques have been developed for industries such as banking, oil and gas,
pharmaceuticals, etc.
• HR Human Resources—is a complete integrated system for supporting the planning and control
of personnel activities.
• PM Plant Maintenance—In a complex manufacturing process maintenance means more than
sweeping the floors. Equipment must be services and rebuilt. These tasks affect the production
plans.
• MM Materials Management—supports the procurement and inventory functions occurring in
day-to-day business operations such as purchasing, inventory management, reorder point
processing, etc.
• QM Quality Management—is a quality control and information system supporting quality
planning, inspection, and control for manufacturing and procurement.
• PP Production Planning—is used to plan and control the manufacturing activities of a company.
This module includes; bills of material, routings, work centers, sales and operations planning,
master production scheduling, material requirements planning, shop floor control, production
orders, product costing, etc.
• SD Sales and Distribution—helps to optimize all the tasks and activities carried out in sales,
delivery and billing. Key elements are; pre-sales support, inquiry processing, quotation
processing, sales order processing, delivery processing, billing and sales information system.
Each of these Modules may have sub-modules designed for specific tasks as detailed below.
System-Wide Features
SAP uses certain system wide features that should be understood at the outset. These are used to
logically, safely and flexibly organize the data in a business enterprise.
• Customizing— is the configuring of the system to represent your organization's legal

structure, reporting requirements and business processes. Internal reporting is a managerial
tool in the daily operations. External reporting is required by governmental units controlling
the legal structure of the corporation, such as, the IRS state taxing authorities, SEC etc.
• Organizational Elements
o Financial—
client is a legal and organizationally independent unit at the highest level in
SAP
company is an independent legal entity within a client
business areas are used to produce profit and loss statements and balanced
sheets across marketing lines
o Materials Management
Purchasing units
Plants
o Sales and Distribution
Sales Organization
Distribution channel
Division

• Master Data is records that remain in the database over an extended period of time.
Examples:
o Customer Master
o Vendor Master
o Material master
o Account Master
This structure eliminates redundant data and is shared by all SAP Modules. It is a critical
aspect of the robustness of the system.
• Employee Self Service—your employees have access to the own HR records over the
Internet.
• Classification is the assignment of object s to a class. Each class has standard characteristics.
• Matchcodes are query tools used to find specific information using search methods.
• Security is administered for objects, profiles and authorizations. Users are only authorized to
see or change the parts of the system required by their job responsibilities.
Business Processes and SAP Functionality
In order to understand a system like SAP a thorough understanding of the events and
relationships that take place in a business is required. It is not enough to just realize the Sales, Production,
Finance and Accounting have jobs to do in a business. The exact details of each action, the timing of that
action and its interrelationships with every other process must be understood. In many large operations
there may be no person that has a complete grasp of the situation. Before an operation can be automated
or computerized a thorough study of the business must be undertaken. This task is called Business
Process Engineering.
Sequential Walk Through
• Sales
o Pre-sales activity—planning and availability support for the sales personnel
o Sales Order—The actual entry of the sales order into the system done by the
salesperson at the point of sales perhaps using a PC and Internet connections.
o Determining where the most efficient source of the ordered product is in inventory
and shipping it.
o Delivery
o Customer Billing
o Customer Payment
• Production
o Sales and Operations Planning SOP where the sales forecasts are used in a production
planning model to check feasibility.
o Master Production Scheduling MPS—The actual pla n for the whole production
process
o Material Requirements Planning MRP—Where the production plan is actually
converted into raw materials input requirements.
o Planned Order—When materials are available and capacity exists this plan is created
and then converted into a
o Production Order.
o Shop Floor Control where the actual production takes place and is registered into the
system as finished goods.

o Purchasing
Requisition—Once the Production manager plans to manufacture something
a requisition for the raw materials required but not on hand must be prepared.
Vendor Selection—made by the purchasing department
Purchase order sent
goods receipt increasing inventory
Invoice verification as it is received from vendor
Payment to vendor.
o Finance and Accounting
Sales events must be captured at the proper time into the ledger system
Inventory must be adjusted to match goods shipped
Inventory must be adjusted to match raw materials received
Inventory must be adjusted to move value from raw materials to work in
process
Inventory must be adjusted to increase finished goods when they are
produced
Accounts Payable must be set up for purchases
Accounts Receivable must reflect goods billed but not yet paid for
Business Process Engineering must not only identify all these steps but must also find the most
efficient way to minimize redundant actions. For example, when sales are made, inventory and
manufacturing plans should be automatically updated. When manufacturing plans are updated raw
materials should be automatically ordered from vendors. When finished goods are shipped customers
should be automatically billed at the same instant. Real situations are far more complex than the simple
explanation above.

Case : SAP R/3 Implementation at Geneva Pharmaceuticals1
Company Background
Geneva Pharmaceuticals, Inc., one of the world’s largest generic drug manufacturers, is the North
American hub for the Generics division of Swiss pharmaceutical and life sciences company Novartis
International AG. Originally founded by Detroit pharmacist Stanley Tutag in 1946, Geneva moved its

headquarters to Broomfield, Colorado in 1974. The company was subsequently acquired by Ciba
Corporation in 1979, which in 1996, merged with Sandoz Ltd. in the largest ever healthcare merger to
form Novartis. Alex Krauer, Chairman of Novartis and former Chairman and CEO of Ciba, commented
on the strengths of the merger: “Strategically, the new company moves into a worldwide leadership
position in life sciences. Novartis holds the number two position [globally] in pharmaceuticals, number
one in crop protection, and has tremendous development potential in nutrition.”
The name “Novartis” comes from the Latin term novae artes or new arts, which eloquently
captures the company’s corporate vision: “to develop new skills in the science of life.” Novartis inherited,
from its parent companies, a 200-year heritage of serving consumers in three core business segments:
healthcare, agribusiness, and nutrition. Today, the Basel (Switzerland) based life sciences company
employs 82,500 employees worldwide, runs 275 affiliate operations in 142 countries, and generates
annual revenues of 32 billion Swiss Francs.
The company’s American Depository Receipts trade on the New York Stock Exchange under the
ticker symbol NVTSY. Novartis’ global leadership in branded pharmaceuticals is complemented by its
generic drugs division, Novartis Generics. This division is headquartered in Kundl (Austria), and its U.S.
operations are managed by Geneva Pharmaceuticals. In 1998, Geneva had revenues of $300 million,
employed nearly 1000 employees, and manufactured over 4.6 billion dosage units of generic drugs.
Geneva portfolio currently includes over 200 products in over 500 package sizes, covering a wide range
of therapeutic categories, such as nervous system disorders, cardio-vascular therapies, and non-steroidal
anti-inflammatory drugs. Its major products include ranitidine, atenolol, diclofenac sodium, ercaf,
metoprolol tartrate, triamterene with hydrochlorothiazide, and trifluoperazine.
Geneva’s business and product information can be obtained from the company web site at
www.genevaRx.com. Generic drugs are pharmaceutically and therapeutically equivalent versions of
brand name drugs with established safety and efficacy. For instance, acetaminophen is the equivalent of
the registered brand name drug Tylenolâ, aspirin is equivalent of Ecotrinâ, and ranitidine HCl is
equivalent of Zantacâ.
This equivalence is tested and certified within the U.S. by the Food and Drug Administration
(FDA), following successful completion of a “bioequivalence study,” in which the blood plasma levels of
the active generic drug in healthy people are compared with that of the corresponding branded drug.
Geneva’s business strategy has emphasized growth in two ways: (1) focused growth over a select range of
product types, and (2) growth via acquisitions. Internal growth was 14 percent in 1998, primarily due to
vigorous growth in the penicillin and cephalosporin businesses. In pursuit of further growth, Geneva
spend $52 million in 1997 to upgrade its annual manufacturing capacity to its current capacity of 6 billion
units, and another $23 million in 1998 in clinical trials and new product development.
Industry and Competitive Position

The generic drug manufacturing industry is fragmented and highly competitive. In 1998, Geneva was the
fifth largest player in this industry, up from its eighth rank in 1997 but still below its second rank in 1996.
The company’s prime competitors fall into three broad categories: (1) generic drugs divisions of major
branded drug companies (e.g., Warrick – a division of Schering-Plough and Apothecon – a division of
Bristol Myers Squibb), (2) independent generic drug manufacturers (e.g., Mylan, Teva Pharmaceuticals,
Barr Laboratories, and Watson Pharmaceuticals), and (3) drug distributors vertically integrating into
generics manufacturing (e.g., AndRx). The industry also has about 200 smaller players specializing in the
manufacture of niche generic products. While Geneva benefited from the financial strength of Novartis,
independent companies typically used public stock markets for funding their growth strategies.
In 1998, about 45 percent of prescriptions for medications in the U.S. were filled with generics.
The trend toward generics can be attributed to the growth of managed care providers such as health
maintenance organizations (HMO), who generally prefer lower cost generic drugs to more expensive
brand name alternatives (generic drugs typically cost 30-50 less than equivalent brands). However, no
single generics manufacturer has benefited from this trend, because distributors and pharmacies view

generic products from different manufacturers as identical substitutes and tend to “autosubstitute” or
freely replace generics from one company with those from another based on product availability and
pricing at that time. Once substituted, it is very difficult to regain that customer account because
pharmacies are disinclined to change product brand, color, and packaging, to avoid confusion among
consumers. In addition, consumer trust toward generics has remained lower, following a generic drug
scandal in the early 1990’s (of which Geneva was not a part).
Margins in the generics sector has therefore remained extremely low, and there is a continuous
pressure on Geneva and its competitors to reduce costs of operations. Opportunities for international
growth are limited because of two reasons. First, consumers in some countries such as Mexico are
generally skeptical about the lack of branding because of their cultural background. Second, U.S. generics
manufacturers are often undercut by competitors from India and China, where abundance of low-cost
labor and less restrictive regulatory requirements (e.g., FDA approval) makes drug manufacturing even
less expensive.
Continuous price pressures has resulted in a number of recent industry mergers and acquisitions
in the generic drugs sector in recent years, as the acquirers seek economies of scale as a means of
reducing costs. The search for higher margins has also led some generics companies to venture into the
branded drugs sector, providing clinical trials, research and development, and additional manufacturing
capacity for branded drugs on an outsourced basis.
Major Business Processes
Geneva’s primary business processes are manufacturing and distribution. The company’s
manufacturing operations are performed at a 600,000 square foot facility in Broomfield (Colorado), while
its two large distribution centers are located in Broomfield and Knoxville (Tennessee). Geneva’s
manufacturing process is scientific, controlled, and highly precise. A long and rigorous FDA approval
process is required prior to commercial production of any drug, whereby the exact formulation of the drug
or its “recipe” is documented. Raw materials are sourced from suppliers (sometimes from foreign
countries such as China), tested for quality (per FDA requirements), weighed (based on dosage
requirements), granulated (i.e., mixed, wetted, dried, milled to specific particle sizes, and blended to
assure content uniformity), and compressed into a tablet or poured into a gelatinous capsule. Some
products require additional coatings to help in digestion, stabilizing, regulating the release of active
ingredients in the human body, or simply to improve taste. Tablets or capsules are then imprinted with the
Geneva logo and a product identification number. Following a final inspection, the medications are
packaged in childproof bottles with a distinctive Geneva label, or inserted into unit-dose blister packs for
shipment.
Manufacturing is done in batches, however, the same batch can be split into multiple product
types such as tablets and capsules, or tablets of different dosages (e.g., 50 mg and 100 mg). Likewise,
finished goods from a batch can be packaged in different types of bottles, based on customer needs. These
variations add several layers of complexity to the standard manufacturing process and requires tracking of
three types of inventory: raw materials, bulk materials, and finished goods, where bulk materials represent
the intermediate stage prior to packaging. In some cases, additional intermediates such as coating solution
is also tracked. Master production scheduling is focused on the manufacture of bulk materials, based on
forecasted demand and replenishment of “safety stocks” at the two distribution centers. Finished goods
production depends on the schedule-to-performance, plus availability of packaging materials (bottles and
blister packs), which are sourced from outside vendors.
Bulk materials and finished goods are warehoused in Broomfield and Knoxville distribution centers (DC)
prior to shipping. Since all manufacturing is done was done at Broomfield, inventory replenishment of
manufactured products is done first at Broomfield and then at Knoxville. To meet additional customer
demand, Geneva also purchases finished goods from smaller manufacturers, who manufacture and
package generic drugs under Geneva’s level. Since most of these outsourcers are located along the east
coast, and hence, they are distributed first to the Knoxville and then to Broomfield. Purchasing is simpler

than manufacturing because it requires no bill of materials, no bulk materials management, and no master
scheduling; Geneva simply converts planned orders to purchase requisitions, and then to purchase orders,
that are invoiced upon delivery.
Geneva supplies to a total of about 250 customers, including distributors (e.g., McKesson,
Cardinal, Bergen), drugstore chains (e.g., Walgreen, Rite-Aid), grocery chains with in-store pharmacies
(e.g., Safeway, Kroger), mail order pharmacies (e.g., Medco, Walgreen), HMOs (e.g., Pacificare, Cigna),
hospitals (e.g., Columbia, St. Luke’s), independent retail pharmacies, and governmental agencies (e.g.,
U.S. Army, Veterans Administration, Federal prisons). About 70 percent of Geneva’s sales goes to
distributors, another 20 percent goes to drugstore chains, while HMOs, government, retail pharmacies,
and others account for the remaining 10 percent. Distributors purchase generic drugs wholesale from
Geneva, and then resell them to retail and mail order pharmacies, who are sometimes direct customers of
Geneva. The volume and dollar amount of transaction vary greatly from one customer to another, and
while distributors are sometimes allow Geneva some lead time to fulfill in a large order, retail pharmacies
typically are unwilling to make that concession. One emerging potential customer segment is Internet-
based drug retailers such as Drugstore.com and PlanetRx.com. These online drugstores do not maintain
any inventory of their own, but instead accept customer orders and pass on those orders to any wholesaler
or manufacturer that can fill those orders in short notice. These small, customized, and unpredictable
orders do not fit well with
Geneva’s wholesale, high-volume production strategy, and hence, the company has decided
against direct retailing to consumers via mail order or the Internet, at least for the near future.
As is standard in the generics industry, Geneva uses a complex incentive system consisting of
“rebates” and “chargebacks” to entice distributors and pharmacies to buy its products. Each drug is
assigned a “published industry price” by industry associations, but Geneva rebates that price to
distributors on their sales contracts. For instance, if the published price is $10, and the rebates assigned to
a distributor is $3, then the contract price on that drug is $7. Rebate amounts are determined by the sales
management based on negotiations with customers. Often times, customers get proposals to buy the
product cheaper from a different manufacturer and ask Geneva for a corresponding discount. Depending
on how badly Geneva wants that particular customer or push that product, it may offer a rebate or
increase an existing rebate. Rebates can vary from one product to another (for the same customer) and/or
from one order volume to another (for the same product).
Likewise, pharmacies ordering Geneva’s products are paid back a fraction of the sales proceeds as
chargebacks. The majority of Geneva’s orders come through EDI. These orders are passed though
multiple filters in an automated order processing system to check if the customer has an active customer
number and sufficient credit, if the item ordered is correct and available in inventory. Customers are then
assigned to either the Broomfield or Knoxville DC based on quantity ordered, delivery expiration dates,
and whether the customer would accept split lots. If the quantity ordered is not available at the primary
DC (say, Knoxville), a second allocation is made to the secondary DC (Broomfield, in this case). If the
order cannot be filled immediately, a backorder will be generated and the Broomfield manufacturing unit
informed of the same. Once filled, the distribution unit will print the order and ship it to the customer, and
send order information to accounts receivable for invoicing. The overall effectiveness of the fulfillment
process is measured by two customer service metrics: (1) the ratio between the number of lines on the
order that can be filled immediately (partial fills allowed) to the total number of lines ordered by the
customer (called “firstfill”), and (2) the percentage of items send from the primary DC. Fill patterns are
important because customers typically prefer to get all items ordered in one shipment. Matching customer
demand to production schedules is often difficult because of speculative buying on the part of customers.
Prices of drugs are typically reassessed at the start of every fiscal year, and a distributor may place a very
large order at the end of the previous year to escape a potential price increase at the start of the next year
(these products would then be stockpiled for reselling at higher prices next year). Likewise, a distributor
may place a large order at the end of its financial year to transfer cash-on-hand to cost-of-goods-sold, for
tax purposes or to ward off a potential acquisition threat. Unfortunately, most generics companies do not
have the built-in capacity to deliver such orders within short time frames, yet inability to fulfill orders

may lead to the loss of an important customer. Safety stocks help meet some of these unforeseen
demands, however maintaining such inventory consumes operating resources and reduce margins further.
SAP R/3 Implementation

Up until 1996, Geneva’s information systems (IS) consisted of a wide array of software programs for
running procurement, manufacturing, accounting, sales, and other mission-critical processes. The primary
hardware platform was IBM AS/400, running multiple operational databases (mostly DB/2) and
connected to desktop microcomputers via a token-ring local area network (LAN). Each business unit had
deployed applications in an ad hoc manner to meet its immediate needs, which were incompatible across
business units. For instance, the manufacturing unit (e.g., materials requirements planning) utilized a
manufacturing application called MacPac, financial accounting used Software/2000, and
planning/budgeting used FYI-Planner. These systems were not interoperable, and data that were shared
across systems (e.g., accounts receivable data was used by order management and financial accounting
packages, customer demand was used in both sales and manufacturing systems) had to be double-booked
and rekeyed manually. This led to higher incidence of data entry errors, higher costs of error processing,
and greater data inconsistency. Further, data was locked within “functional silos” and were unable to
support processes that cut across multiple business units (e.g., end-to-end supply chain management). It
was apparent that a common, integrated company-wide solution would not only improve data consistency
and accuracy, but also reduce system maintenance costs (e.g., data reentry and error correction) and
enable implementation of new value-added processes across business units.
In view of these limitations, in 1996, corporate management at Geneva initiated a search for technology
solutions that could streamline its internal processes, lower costs of operations, and strategically position
the company to take advantage of new value-added processes. More specifically, it wanted an enterprise
resource planning (ERP) software that could: (1) implement best practices in business processes, (2)
provide operational efficiency by integrating data across business units, (3) reduce errors due to incorrect
keying or rekeying of data, (4) reduce system maintenance costs by standardizing business data, (5) be
flexible enough to integrate with new systems (as more companies are acquired), (6) support growth in
product and customer categories, and (7) is Y2K (year2000) compliant. The worldwide divisions of
Novartis were considering two ERP packages at that time: BPCS from Software Systems Associates and
R/3 system from SAP. Eventually, branded drug divisions decided to standardize their data processing
environment using BPCS, and generics agreed on deploying R/3.2 A brief description of the R/3 software
is provided in the below exhibits.





UNIT VI
Lesson 40 - Case Analysis on Information Systems
Case: Tennessee Valley Authority (TVA)
The Tennessee Valley Authority (TVA) is a quasi-public federal organization head-quartered in

Knoxville, Tennessee, that was founded in 1933. It provides electric power; flood control; navigation; and
agricultural, economic, and industrial development through the Southeastern United States. It is the
nation’s largest electric utility. It makes most of its money ($5.1 billion in 1992) by selling electric power
to regional power associations. It provides power to more than 160 municipal and cooperative power
distributors who service more than 7 million consumers. In addition, special projects are funded by
Congress (amounting to $135 million in 1992). The 19,500 employees are divided into several business
units, including finance, power generation, marketing, and navigation. The IS department consists of 925
employees and has an annual budget of $100 million. Through restructuring, by mid-1995 the total
number of employees had been reduced to 16,500.
Like other businesses, the TVA faces a changing environment with deregulation. For years, it was
the only supplier of electricity in its region cooperatives and municipalities signed agreements to purchase
power solely from TVA. Many of these contracts had extended time frames of 35 to 50 years. Many of
these contracts are now due for renegotiation, and other utilities are eager to expand their markets.
Additionally, the federal government is encouraging competition in the production of electricity. As a
result, TVA has to become more cost conscious. As of 1994, the Energy Policy Act of 1992 effectively
frees customers to choose the electric company they wish to use. Wholesale corporate utility customers
can already buy their electricity from a variety of sources. It is unclear at this time whether individual
households will have the option of selecting power providers. The act is primarily designed to provide
multiple choices to large factories, power distributors/resellers, and municipal utilities.
Management and Employees
The TVA is governed by a three-person board of directors, with one of them appoint-ed as the
head of the board. The day-to-day activities are governed by the general manager, the comptroller, the
general counsel, the chief budget officer and the director of information. The separate business units are
largely independent of each other. They have separate divisional leaders, separate budgets, and different
objectives that occasionally conflict. Also, many of the offices are located in different cities.
The TVA has an interesting history in terms of management and labor relations. Al-though it is
technically an agency within the federal government, its employees are not sub-ject to Civil Service
regulations. Congress decided that because of the technical nature of the agency, it required highly trained
employees, so it should be free to hire employees from the national job market without the political
considerations involved in the Civil Service system. In 1940, TVA became the first U.S. federal agency to
adopt collective bargaining. By 1977, 99 percent of eligible trade and labor employees were members of a
union. Even management level and “white-collar” employees are members, with 87 percent of eligible
salaried workers belonging to an employee union.
At the TVA, membership in unions is encouraged by personnel rules and practices. Employee
promotions and raises are based on merit evaluations. As part of the employee merit evaluation system,
membership in a union is considered a sign of professional competency, merit, and efficiency. Hence,
membership in a union virtually guarantees job tenure and merit raises.

Because TVA is a federal agency, an unusual problem has arisen. The TVA Act of 1933 that
established the agency set a maximum salary of $10,000 for members of the board of directors. More
importantly, it stipulated that no employee could receive a higher salary than the amount paid to the
directors. Because this value was fixed by Congress, it could only be changed by Congress by passing
new legislation. Consequently, the value is not changed often and the TVA has had trouble hiring and
keeping professional employees. As a result, the agency has a history of relying on outside consultants
who are not directly affected by the salary cap because they are paid for individual tasks. Recent MIS
Activity Prior to 1992, the IS department was highly fragmented; each business unit essentially had its
own IS department. Computer hardware consisted primarily of large IBM and compatible machines
centrally located in the Knoxville offices. Data management and soft-ware development were largely left
to the individual business units. Most development of software was in COBOL. The business units were
happy controlling their own group of IS employees. However, there was considerable duplication of
effort. Additionally, the individual departments and their software tended to be maintained separately
from other departments. There were virtually no corporate standards, so hardware and software purchased
and designed for each business unit often required major modifications whenever someone wanted to
share data across departments. Overall, the IS staff was spread too thin, and they were developing
redundant, incompatible Overall responsibility for the MIS department technically belonged to a
centralized core MIS team. However, the operating divisions tended to mistrust the central MIS
department. They had earned a reputation of being late and over budget with most projects.
The central MIS team was also accused of being heavily biased in favor of solutions involving
centralized programs written in COBOL. It was generally accepted that the MIS team would always
advocate a solution that they knew best—regardless of the technical merits of the alternatives. As a result,
the business units often turned to outside consultants and programmers to create new information
systems, bypassing the internal IS department completely. For instance, in 1992, the finance department
called on Coopers & Lybrand and Oracle Corporation to develop a major new client-server based
financial system. In 1991, TVA signed a five-year contract to purchase up to $60 million worth of
personal computers and local area network equipment from Concept Automation Inc of Sterling, Virginia.
Part of the goal is to shift the company toward an open systems environment. Managers who need PCs
within the company will order them from TVA offices in Chattanooga. The bulk of the purchases are
expected to come from the headquarters in Knoxville, but offices in Huntsville, Alabama, and
Chattanooga are expected to buy several PCs through the contract as well. In early 1992, TVA took the
first steps to implement an agency wide geographic in-formation system. The authority awarded a
$750,000 contract to ESRI for Arc/Info running on Sun workstations. The goal is to create a $13-million
Automated Land Information Sys-tem over eight years. The goal is to provide better management data to
foresters, biologists, and engineers throughout the organization. Centralization In 1990, the head of IS
decided to centralize the IS department to reduce duplication and help control costs. This centralization
offended the heads of the various business units, largely because they saw it as a loss of control. In the
process of consolidating the IS departments, the head of IS also offended the IS workers because he was
stressing a shift to a client-server approach. In particular, he tried to emphasize development using the
Oracle database management system, signing a $16-million contract. The IS programmers and analysts
felt that management was “shoving Oracle down their throats.” The IS department is represented by three
different unions, which provide alternative channels for complaints and grievances. As a result, the initial
agreements with Oracle were investigated by the TVA inspector general for alleged collusion and
kickbacks. After three years of investigation, the inspector cleared the contract. A New IS Director and a
New Plan In August 1992, the IS director was replaced by Robert Yates, previously the corporate
treasurer to “clean up the mess” in the IS department. Yates noted that there were “a lot of turf battles, no
clear-cut domains, and built-in conflicts of interest.” Yates consulted with N. Dean Meyer and Associates,
Inc., and with the IS workers to help create a new IS structure that would satisfy the business units, please
the IS workers, and improve the competitive position of TVA. The new plan basically keeps the current
(centralized) structure. It organizes the IS workers into four categories:

(1) Service bureaus consisting of IS operations staff, maintenance, administration, and PC

support;
(2) Technologists consisting of programmers, application specialists, database administrators, and
various technical experts;
(3) A consultancy of about 30 members who will help the business units determine their needs as
well as market the IS capabilities; and
(4) A small number of architects to define corporate standards. Yates also plans to institute a
charge-back sys-tem to bill the business units for IS services. He is concerned that they look at IS as a
“free good”; hence there would be incentive to overuse the IS department, instead of searching out other
solutions. In 1993, the MIS department began searching for a management software tool to help them
centralize the administration of all the workstations throughout the company.
For example, in 1993 there were more than 100 Sun high-end workstations and 400 smaller
Sparcstation 2 machines in use. Robert Khym, TVA’s manager of distributed systems soft-ware support,
noted that “The next step will be finding something that will integrate all of our open systems.”
In 1993, TVA began replacing its mainframe computers with Unix-based midrange computers.
Each of the 24 dams, 12 fossil fuel plants and 4 nuclear reactor plants operate as separate entities. The
agency wants to install lower-cost open-system minicomputers at each site. There is limited information
flow between the various sites, but TVA is in the process of installing a wide area network to allow easier
transfer of financial data. The existing IBM mainframes will be kept as centralized file servers.
As part of its consolidation plan, TVA signed a contract with PeopleSoft Inc. to use that
company’s client-server payroll software package. After some alleged problems about making the
package work with the IBM DB2 database applications, the TVA inspector general’s office called a halt
to the installation and began an investigation into the purchasing process.
TVA in the 1970s
The GAO reports that the TVA was experiencing a huge growth in the use of electricity in the
late 1960s and early 1970s, when power sales were growing at a steady rate and were expected to double
every 10 years. In the Tennessee Valley, the number of electricity customers rose to over 2 million in the
1960s and about 30 percent of all the homes were heated with electricity. By 1970, TVA customers used
nearly twice as much electricity as the national average. At that time, TVA was experiencing an annual
growth rate of about 8 percent in demand for electricity, and TVA’s forecasts through the mid-1970s were
showing continued high growth in demand.
In 1966, TVA announced plans to build 17 new nuclear plants in seven states. Many other utility
companies announced similar (though less ambitious) plans. The oil crises of 1973 and 1978, the Three
Mile Island disaster of 1979, and construction problems and cost overruns caused most companies to
cancel the construction of the majority of nuclear plants. A changing regulatory environment of the 1980s
also encouraged electric utilities to focus on conservation instead of new construction. Encouraging
customers to add insulation, purchase more energy-efficient appliances, and employ newer heating and
cooling systems resulted in a significantly smaller growth rate in consumption. By 1984, after investing
$5 billion in construction, TVA canceled 8 of the 17 plants.
Of TVA’s nine remaining nuclear sites, three were operational in 1995 (Browns Ferry 2,
Sequoyah 1 and Sequoyah 2). After 22 years of construction, Watts Bar 1 was be-ginning final testing and
expected to be placed on-line in early 1996. One unit (Browns Ferry 3) began operations but was shut
down because of repeated problems. Four other units were placed into “mothball” status, pending an
analysis to determine whether they should be continued, converted to alternative fuels, or shut down
completely. Total TVA spending on nuclear facilities is more than $25 billion, of which only $5 billion
applies to functional plants. TVA is the only U.S. utility still actively constructing nuclear plants. The $25

billion constitutes the bulk of the $26 billion debt (mostly public bonds) of TVA, but the nuclear plants
generated only 14 percent of TVA’s total power supply in 1994.
TVA in the 1990s

TVA is under federal mandate to fund its electricity production from ongoing operations. By its internal
accounting methods, TVA is meeting this mandate; however, $14 billion of the nuclear construction debt
is not being financed from current operations. In 1995, TVA had a total debt of $26 billion, with
financing costs of $1.9 billion a year (35 percent of its power revenues). TVA faces a Congressionally
imposed debt ceiling of $30 billion, and TVA expects to increase its debt to about $28 billion by 1997—
in part to cover final production costs at Watts Bar, in part to cover interest payments on its debt. As a
federal agency, TVA cannot sell stock (like most traditional utilities), so all funds must be raised from
bond sales. Although these sales are not guaranteed by the federal government, some investors believe
that the federal government will not allow TVA to default on the bonds. Consequently, TVA has a slight
advantage over potential competitors in terms of interest rates. Similarly, TVA does not pay federal
income taxes.
TVA also anticipates the need for substantial expenditures to improve existing hydroelectric and
coal-fired plants. Additional expenses will also be incurred in bringing all of the coal-fired plants into
compliance with the Clean Air Act. Based on preliminary estimates, TVA anticipates spending between
$1.1 and $1.6 billion between 1995 and 2015 (in constant 1994 dollars).
In public statements, TVA repeatedly emphasized that they have not raised electricity rates in
nine years, and they are trying to hold them stable for at least 10 years. Nonetheless, TVA is not the
lowest-cost producer in the area. However, for the immediate future, other firms are prohibited from
selling electricity to TVA’s customers.
As part of the Energy Policy Act of 1992, TVA is conducting an integrated resource planning
(IRP) process—largely to determine future goals, changes in production and operations, and the least-cost
means of providing power. TVA is conducting the plan with several interdisciplinary teams:
Issues and Values Translation Team
Evaluation Criteria Team
Load Forecasting Team
Existing Capabilities Team
Supply-Side Options Team
Environment Team
Rankings Team
Strategy Development Team
Uncertainties Team
Integration Team
Each of these teams is responsible for identifying problems, making forecasts, and presenting and
evaluating alternatives. Many of the teams use statistical and computer simulation models to test
assumptions and evaluate the alternatives. The final report will present the reduced list of options to the
governing board.
In 1998, the TVA chairman became frustrated with negotiating with Congress. He offered to drop
all federal subsidies—in exchange for complete control of the company and its resources. He is beginning
to concentrate on the opening of the electricity market to competition. On the other hand, several people
have complained about the possibility of losing federal subsidies for the administration of thousands of
acres of land and lakes open to the public.
TVA Financial Performance
In 1995, the Congressional Government Accounting Office (GAO) undertook a comprehensive
investigation of TVA and its problems. The GAO’s financial comparison of TVA with potential future
competitors is particularly useful. Additional comments and statistics are available in the total report.
