CHAPTER OUTLINE
1. A group is defined as two or more individuals, interacting and interdependent, who have
come together to achieve particular objectives.
2. Groups can be either formal or informal.
• Formal groups—those defined by the organisation’s structure, with designated
work assignments establishing tasks.
• The behaviours that one should engage in are stipulated by and directed toward
organisational goals.
• An airline flight crew is an example of a formal group.
• Informal groups—alliances that are neither formally structured nor
organisationally determined
• Natural formations in the work environment in response to the need for social
contact.
• Three employees from different departments who regularly eat lunch together is
an informal group.
3. It is possible to sub-classify groups as command, task, interest, or friendship groups.
• Command groups are determined by the organisation chart, and are composed of
the individuals who report to a given manager.
• Task groups are also organisationally determined and represent those working
together to complete a job task. A task group’s boundaries are not limited to its
immediate hierarchical superior. It can cross command relationships. All
command groups are also task groups, but the reverse need not be true.
• An interest group. People who affiliate to attain a specific objective with which
each is concerned. For example employees who band together to have their
holiday schedules altered
Instructor’s Manual: Robbins Organisational Behaviour 5e © 2008 Pearson Education Australia 9-1
• Friendship groups often develop because the individual members have one or
more common characteristics. Social alliances, which frequently extend outside
the work situation, can be based on similar age or ethnic heritage.
4. Informal groups satisfy their members’ social needs.
• These types of interactions among individuals, even though informal, deeply
affect their behaviour and performance.
• There is no single reason why individuals join groups.
• Table 7.1 summarises the most popular reasons people have for joining groups
Groups generally pass through a standardised sequence in their evolution (See Figure 7.1)
1. Forming:
• Characterised by a great deal of uncertainty about the group’s purpose, structure, and
leadership.
• Members are trying to determine what types of behaviour are acceptable.
• Stage is complete when members have begun to think of themselves as part of a group.
2. Storming:
• One of intragroup conflict. Members accept the existence of the group, but there is resistance
to constraints on individuality.
• Conflict over who will control the group.
• When complete, there will be a relatively clear hierarchy of leadership within the group.
3. Norming:
• One in which close relationships develop and the group demonstrates cohesiveness.
• There is now a strong sense of group identity and camaraderie.
• Stage is complete when the group structure solidifies and the group has assimilated a common
set of expectations of what defines correct member behaviour.
4. Performing:
• The structure at this point is fully functional and accepted.
• Group energy has moved from getting to know and understand each other to performing.
• For permanent work groups, performing is the last stage in their development.
5. Adjourning:
• For temporary committees, teams, task forces, and similar groups that have a limited task to
perform, there is an adjourning stage.
• In this stage, the group prepares for its disbandment. Attention is directed toward wrapping up
activities.
• Responses of group members vary in this stage. Some are upbeat, basking in the group’s
accomplishments. Others may be depressed over the loss of camaraderie and friendships.
6. Many assume that a group becomes more effective as it progresses through the first four stages.
While generally true, what makes a group effective is more complex. Under some conditions,
high levels of conflict are conducive to high group performance.
7. Groups do not always proceed clearly from one stage to the next. Sometimes several
stages go on simultaneously, as when groups are storming and performing. Groups even
occasionally regress to previous stages.
8. Another problem is that it ignores organisational context. For instance, a study of a
cockpit crew in an airliner found that, within ten minutes, three strangers assigned to fly
together for the first time had become a high-performing group.
Instructor’s Manual: Robbins Organisational Behaviour 5e © 2008 Pearson Education Australia 9-2
9. The strong organisational context provides the rules, task definitions, information, and
resources needed for the group to perform.
Introduction
Work groups have properties that shape the behaviour of members and make it possible to explain and
predict a large portion of individual behaviour within the group as well as the performance of the
group itself.
A. Roles
• All group members are actors, each playing a role.
• Roles are a set of expected behaviour patterns attributed to someone occupying a given
position in a social unit.
• We are required to play a number of diverse roles, both on and off our jobs.
1. Role identity
• There are certain attitudes and actual behaviours consistent with a role, and they create the
role identity.
• People have the ability to shift roles rapidly when they recognise that the situation and its
demands clearly require major changes.
• For instance, when union stewards were promoted to supervisory positions, it was found that
their attitudes changed from pro-union to pro-management within a few months of their
promotion.
2. Role perception
• One’s view of how one is supposed to act in a given situation is a role perception.
• We get these perceptions from stimuli all around us—friends, books, movies, television.
• The primary reason that apprenticeship programs exist is to allow beginners to watch an
“expert,” so that they can learn to act as they are supposed to.
3. Role expectations
• How others believe you should act in a given situation.
• How you behave is determined to a large extent by the role defined in the context in which
you are acting.
• The psychological contract is an unwritten agreement that exists between employees and their
employer.
• It sets out mutual expectations—what management expects from workers, and vice versa.
• It defines the behavioural expectations that go with every role.
• If role expectations as implied are not met:
o If management is derelict in keeping up its part of the bargain, we can expect negative
repercussions on employee performance and satisfaction.
o When employees fail to live up to expectations, the result is usually some form of
disciplinary action up to and including firing.
4. Role conflict:
• Role conflict results when an individual is confronted by divergent role expectations.
• It exists when compliance with one role requirement may make more difficult the compliance
with another.
• At the extreme, it would include situations in which two or more role expectations are
mutually contradictory.
B. Norms
Instructor’s Manual: Robbins Organisational Behaviour 5e © 2008 Pearson Education Australia 9-3
1. All groups have norms—acceptable standards of behaviour that are shared by the group’s
members.
2. Norms tell members what they ought and ought not to do under certain circumstances.
3. From an individual’s standpoint, they tell what is expected of you in certain situations.
4. Conformity
• As a member of a group, you desire acceptance by the group. Because of your desire for
acceptance, you are susceptible to conforming to the group’s norms.
• There is considerable evidence that groups can place strong pressures on individual members
to change their attitudes and behaviours to conform to the group’s standard.
• Individuals conform to the important groups to which they belong or hope to belong. The
important groups are referred to as reference groups.
• The reference group is characterised as one where the person is aware of the others; the person
defines himself or herself as a member, or would like to be a member; and the person feels
that the group members are significant to him/her.
• All groups do not impose equal conformity pressures on their members.
C. Status
Instructor’s Manual: Robbins Organisational Behaviour 5e © 2008 Pearson Education Australia 9-4
1. Status is a socially defined position or rank given to groups or group members by others. We live
in a class-structured society despite all attempts to make it more egalitarian.
• Status is an important factor in understanding human behaviour, because it is a significant
motivator and has major behavioural consequences when individuals perceive a disparity
between what they believe their status to be and what others perceive it to be.
2. What Determines Status?
• Status characteristics theory – differences in status characteristics create status hierarchies
within groups.
• Status derived from one of three sources: the power a person wields over others; a person’s
ability to contribute to group’s goals; individual’s personal characteristics.
o People who control the outcomes of a group through their power tend to be perceived
as high in status (e.g., a group’s formal leader or manager).
o People whose contributions are critical to the group’s success also tend to have high
status (e.g., outstanding performers on sports teams).
o Someone who has personal characteristics that are positively valued by the group
(such as good looks, intelligence, money or a friendly personality) will typically have
higher status than someone who has fewer valued attributes.
5. Status Inequity:
• When inequity is perceived, it creates disequilibrium that results in corrective behaviour.
• The concept of equity applies to status. People expect rewards to be proportionate to costs
incurred.
• The trappings of formal positions are also important elements in maintaining equity. When
we believe there is an inequity between the perceived ranking of an individual and the status
accoutrements that person is given by the organisation, we are experiencing status
incongruence.
• Groups generally agree within themselves on status criteria.
• However, individuals can find themselves in a conflict situation when they move between
groups whose status criteria are different or when they join groups whose members have
heterogeneous backgrounds.
• This can be a particular problem when management creates teams made up of employees from
across varied functions within the organisation.
D. Size
1. The size of a group affects the group’s overall behaviour, but the effect depends on the dependent
variables we look at:
• Smaller groups are faster at completing tasks than are larger ones.
• If the group is engaged in problem solving, large groups consistently do better.
• Large groups—a dozen or more members—are good for gaining diverse input.
• Smaller groups—five to seven members— tend to be more effective for taking action.
2. Social loafing is the tendency for individuals to expend less effort when working collectively than
when working individually.
• It directly challenges the logic that the productivity of the group as a whole should at least
equal the sum of the productivity of each individual in that group.
Instructor’s Manual: Robbins Organisational Behaviour 5e © 2008 Pearson Education Australia 9-5
o There will be a reduction in efficiency where individuals think that their contribution
cannot be measured.
4. Implications for OB:
• Where managers use collective work situations to enhance morale and teamwork, they must
also provide means by which individual efforts can be identified.
• If this is not done, management must weigh the potential losses in productivity from using
groups against any possible gains in worker satisfaction.
5. Other conclusions from research on group size:
• Groups with an odd number of members tend to be preferable.
o They eliminate the possibility of ties when votes are taken.
• Groups made up of five or seven members do a pretty good job of exercising the best elements
of both small and large groups.
o Large enough to form a majority and allow for diverse input
o Small enough to avoid the negative outcomes often associated with large groups, such as
domination by a few members, development of subgroups, inhibited participation by some
members, and excessive time taken to reach a decision.
E. Cohesiveness
1. Groups differ in their cohesiveness - the degree to which members are attracted to each other and
are motivated to stay in the group.
2. Cohesiveness is important because it has been found to be related to the group’s productivity.
Decision-making groups may be widely used in organisations, whether or not they are preferable to
individual decisions depends on many factors.
Instructor’s Manual: Robbins Organisational Behaviour 5e © 2008 Pearson Education Australia 9-6
• Groups lead to increased acceptance of a solution.
o Group members who participated in making a decision are likely to enthusiastically
support the decision and encourage others to accept it.
2. Weaknesses of group decision-making:
• They are time consuming.
• There is a conformity pressure in groups.
• Group discussion can be dominated by one or a few members.
• Group decisions suffer from ambiguous responsibility.
3. Effectiveness and efficiency:
• Whether groups are more effective than individuals depends on the criteria you use.
• In terms of accuracy, group decisions will tend to be more accurate.
• On the average, groups make better-quality decisions than individuals.
• If decision effectiveness is defined in terms of speed, individuals are superior.
• If creativity is important, groups tend to be more effective than individuals.
• If effectiveness means the degree of acceptance the final solution achieves, groups are better.
4. Efficiency
• Groups almost always stack up as a poor second to the individual decision maker.
• The exceptions tend to be those instances where, to achieve comparable quantities of diverse
input, the single decision maker must spend a great deal of time reviewing files and talking to
people.
5. Summary
• Groups offer an excellent vehicle for performing many of the steps in the decision-making
process.
• They are a source of both breadth and depth of input for information gathering.
• When the final solution is agreed upon, there are more people in a group decision to support
and implement it.
• Group decisions consume time, create internal conflicts, and generate pressures toward
conformity.
• Groupthink and groupshift are two by-products of group decision-making. Briefly, the
differences between the two are:
• Groupthink is related to norms. It describes situations in which group pressures for conformity
deter the group from critically appraising unusual, minority, or unpopular views.
• Groupthink is a disease that attacks many groups and can dramatically hinder performance.
• Groupshift is a change in decision risk. It indicates that in discussing a given set of alternatives
and arriving at a solution, group members tend to exaggerate the initial positions that they hold.
In some situations, caution dominates, and there is a conservative shift.
• The evidence indicates that groups tend toward a risky shift.
Instructor’s Manual: Robbins Organisational Behaviour 5e © 2008 Pearson Education Australia 9-7
2. Brainstorming
• It is meant to overcome pressures for conformity in the interacting group that retard the
development of creative alternatives. It does this by utilising an idea-generation process that
specifically encourages any and all alternatives while withholding any criticism of those
alternatives.
• In a typical brainstorming session, a half dozen to a dozen people sit around a table.
• The process:
• The group leader states the problem clearly.
• Members then “free-wheel” as many alternatives as they can in a given length of
time. No criticism is allowed, and all the alternatives are recorded for later
discussion and analysis.
• One idea stimulates others, and group members are encouraged to “think the
unusual.”
• Brainstorming may indeed generate ideas, but not very efficiently.
o Research consistently shows that individuals working along will generate more ideas
than a group because of ‘production blocking’.
o When there are many people talking at once it blocks the through process and
eventually impedes the sharing of ideas.
3. The nominal group technique
• Restricts discussion or interpersonal communication during the decision-making process.
• Group members are all physically present, but members operate independently.
• Specifically, a problem is presented, and then the following steps take place:
• Members meet as a group but, before any discussion takes place, each member
independently writes down his or her ideas on the problem.
• After this silent period, each member presents one idea to the group. Each member
takes his or her turn.
• The group now discusses the ideas for clarity and evaluates them.
• Each group member silently and independently rank-orders the ideas.
• The idea with the highest aggregate ranking determines the final decision.
• The advantage of the nominal group technique is that it permits the group to meeting formally
but doesn’t restrict independent thinking.
4. Electronic meeting
• The computer-assisted group or electronic meeting blends the nominal group technique with
sophisticated computer technology.
• Once the technology is in place, the concept is simple. Up to 50 people sit around a
horseshoe-shaped table, empty except for a series of computer terminals.
• Issues are presented to participants, and they type their responses onto their computer screen.
• Individual comments, as well as aggregate votes, are displayed on a projection screen.
• The proposed advantages of electronic meetings are anonymity, honesty and speed.
• The early evidence, however, indicates that electronic meetings don’t achieve most of their
proposed benefits. Evaluations of numerous studies found that electronic meetings:
o actually led to decreased group effectiveness
o required more time to complete tasks
o resulted in reduced member satisfaction when compared to face-to-face groups.
• Table 7.3 offers an evaluation of the different types of group decision making techniques and
the effectiveness of the decision.
Introduction
Instructor’s Manual: Robbins Organisational Behaviour 5e © 2008 Pearson Education Australia 9-8
Work teams are different from work groups (See Figure 7.4).
1. A work group is a group that interacts primarily to share information and to make decisions to
help each member perform within his or her area of responsibility. Work groups have no need or
opportunity to engage in collective work that requires joint effort. Their performance is the
summation of each group member’s individual contribution. There is no positive synergy to
create an overall performance grater than the sum of the inputs.
2. Work teams, are able to leverage positive synergies through individual complementarities and a
coordinated effort, which creates an overall level of performance that is greater than the sum of
the inputs.
1. Factors for creating effective teams have been summarised in the model found in Figure 7.5.
2 The discussion is based on the above model. There are two caveats:
• First, teams differ in form and structure—be careful not to rigidly apply the model’s
predictions to all teams.
• Second, the model assumes that it is already been determined that teamwork is preferable over
individual work.
Team effectiveness in this model means objective measures of the team’s productivity,
managers’ ratings of the team’s performance, and aggregate measures of member satisfaction.
A. Context
There are four contextual factors that appear to be most significantly are related to team performance:
1. Adequate resources:
• All work teams rely on resources outside the group to sustain it.
• A scarcity of resources directly reduces the ability of the team to perform its job
effectively.
• As one set of researchers concluded, “Perhaps one of the most important characteristics
of an effective work group is the support the group receives from the organisation.”
3. Climate of Trust:
• Members of effective teams trust each other and exhibit trust in their leaders.
Instructor’s Manual: Robbins Organisational Behaviour 5e © 2008 Pearson Education Australia 9-9
• Interpersonal trust among team members facilitates cooperation, reduces the need to
monitor each member’s behaviour, and bonds members around the belief that others
on the team won’t take advantage of them.
• When members trust their leadership they are more willing to commit to their
leader’s goals and decisions.
B. Composition
1. Abilities of members:
• Part of a team’s performance depends on the knowledge, skills and abilities of its individual
members.
• Teams require three different types of skills, technical expertise, problem-solving and
decision-making skills, good listening, feedback, conflict resolution, and other interpersonal
skills
• The right mix is crucial. It is not uncommon for one or more members to take
responsibility to learn the skills in which the group is deficient, thereby allowing the team
to reach its full potential.
• When the task entails considerable thought, high-ability teams (teams composed of mostly
intelligent members) do better, especially when the workload is distributed evenly.
• When tasks are simple, high-ability teams don’t perform as well, perhaps because, in such
tasks, high-ability teams become bored and turn their attention to other activities that are
more stimulating, whereas low-ability teams stay on task.
• Smart team leaders help less intelligent team members when they struggle with a task. But a
less intelligent leader can neutralise the effect of a high-ability team.
2. Personality:
• Many of the dimensions identified in the Big Five personality model have shown to be
relevant to team effectiveness.
• Teams that rate higher in mean levels of extraversion, agreeableness, conscientiousness, and
emotional stability tend to receive higher managerial ratings for team performance.
• The variance in personality characteristics may be more important than the mean. A single
team member who lacks a minimal level of, say, agreeableness can negatively affect the
whole team’s performance.
• Conscientious people are valuable because they are good at ‘backing up’ fellow team
members, and they are also good at sensing when that support is truly needed.
• It is best to staff teams with people who are extraverted, agreeable, conscientious,
emotionally stable and open.
3. Allocating roles
• Teams have different needs, and people should be selected for a team to ensure that there is
diversity and that all various roles are filled.
• Managers need to understand the individual strengths that each person can bring to a team,
select members with their strengths in mind, and allocate work assignments accordingly.
Instructor’s Manual: Robbins Organisational Behaviour 5e © 2008 Pearson Education Australia 9-10
4. Diversity
• Most team activities require a variety of skills and knowledge, therefore on cognitive,
creativity-demanding tasks, teams on cognitive, creativity-demanding tasks are more
effective.
• Diversity in terms of personality, gender, age, education, functional specialisation, and
experience increase the probability that the team will complete its tasks effectively.
• The team may be more conflict laden and less expedient but more effective than a
homogeneous team.
• One study found that white males performed the worst relative to mixed race and gender
teams, or teams of only females.
• Over time, however, culturally diverse teams function effectively over time.
• The degree to which members of a group share common characteristics such as age, sex, race
educational level, or length of service, is termed group demography.
• Groups, teams and organisations are comprised of cohorts, which are defined as individuals
who hold a common attribute.
• Research on cohort differences suggests that the composition of a team may be an important
predictor of turnover. Large differences in a single team will lead to turnover, whereas if
everyone is moderately dissimilar the feelings of being an outsider are reduced.
5. Size of teams:
• Generally speaking, the most effective teams have fewer than ten people. Four to five people
may be necessary to develop the diversity of views and skills.
• Large teams have difficulty getting much done and have trouble coordinating with one
another, especially when time pressure is present.
6. Member flexibility:
• This is an obvious plus because it greatly improves its adaptability and makes it less reliant on
any single member.
7. Member preferences:
• Not every employee is a team player.
• Given the option, many employees will select themselves out of team participation.
• High performing teams are likely to be composed of people who prefer working as part of a
group.
Instructor Note: See the box “Applying the Knowledge - Shaping Team Players” on p. 207
to review managers’ options for turning individuals into team players.
C. Work Design
1. Effective teams need to work together and take collective responsibility to complete significant
tasks.
2. The work-design category includes variables like freedom and autonomy, the opportunity to
utilise different skills and talents, the ability to complete a whole and identifiable task or product,
and working on a task or project that has a substantial impact on others.
3. The evidence indicates that work-design characteristics enhance member motivation and increase
team effectiveness.
Instructor’s Manual: Robbins Organisational Behaviour 5e © 2008 Pearson Education Australia 9-11
D. Process
Processes are important to team effectiveness because of their effect on social loafing and synergy
(Figure 7.7).
1. A Common Purpose:
• Effective teams have a common and meaningful purpose that provides direction, momentum,
and commitment for members.
• This purpose is a vision. It is broader than specific goals.
2. Specific goals:
• Successful teams translate their common purpose into specific, measurable, and realistic
performance goals. They energise the team.
• Specific goals facilitate clear communication and help teams maintain their focus on results.
Team goals should be challenging.
• Team goals should be challenging, to raise team performance on those criteria for which they
are set.
3. Team efficacy:
• Effective teams have confidence in themselves and believe they can succeed—this is team
efficacy. Success breeds success.
• Management can increase team efficacy by helping the team to achieve small successes and
skill training. Small successes build team confidence.
• Providing training to improve members’ technical and interpersonal skills can also assist: the
greater the abilities of team members, the greater the likelihood that the team will develop
confidence and the capability to deliver that confidence.
4. Conflict levels:
• Conflict on a team is not necessarily bad. Teams that are completely void of conflict are
likely to become apathetic and stagnant.
• Relationship conflicts—those based on interpersonal incompatibilities, tension, and animosity
toward others—are almost always dysfunctional.
• On teams performing non-routine activities, disagreements among members about task
content (called task conflicts) is not detrimental. It is often beneficial because it lessens the
likelihood of groupthink.
5. Social loafing:
• Individuals can hide inside a group. Effective teams undermine this tendency by holding
themselves accountable at both the individual and team level.
Instructor Note: Students should complete the Self-Assessment Exercise II.B.6 “How Good
Am I At Building And Leading A Team” The results from this exercise directly relate to the
chapter material.
Students should consider the following after they have completed the exercises:
• Did you score as high as you though you would? Why or why not?
• Do you think your score can be improved? If so, how? If not, why not?
• Do you think there are team players? If yes, what are their behaviours?
Instructor’s Manual: Robbins Organisational Behaviour 5e © 2008 Pearson Education Australia 9-12
Applying the knowledge: Shaping Team Players (p. 207)
The following summarises the primary options managers have for trying to turn individuals into team
players.
1. Selection:
• Some people already possess the interpersonal skills to be effective team players. Care should
be taken to ensure that candidates could fulfil their team roles as well as technical
requirements.
• Many job candidates do not have team skills:
• This is especially true for those socialised around individual contributions.
• The candidates can undergo training to “make them into team players.”
• In established organisations that decide to redesign jobs around teams, it should be
expected that some employees will resist being team players and may be untrainable.
2. Training:
• A large proportion of people raised on the importance of individual accomplishment can be
trained to become team players.
• Workshops help employees improve their problem-solving, communication, negotiation,
conflict-management, and coaching skills.
• Employees also learn the five-stage group development model.
3. Rewards:
• The reward system needs to encourage cooperative efforts rather than competitive ones.
Promotions, pay raises, and other forms of recognition should be given to individuals for how
effective they are as a collaborative team member.
• This does not mean individual contribution is ignored; rather, it is balanced with selfless
contributions to the team.
• There are other intrinsic rewards to being on a team. One example is that teams provide
camaraderie:
• It is exciting and satisfying to be an integral part of a successful team.
• The opportunity to engage in personal development
Instructor Note: The Student Challenge (p. 205) describes the problem a managers faces
when the team at hand is casual, after-school, or uni students. This relates directly to the
teams’ composition (no formal training in task performance), and to the process concept.
Have the students read this challenge in groups and think of effective ways to address this
team’s performance.
Instructor’s Manual: Robbins Organisational Behaviour 5e © 2008 Pearson Education Australia 9-13
group norms aim to restrict output. Similarly, norms that support antisocial behaviour
increase the likelihood that individuals will engage in deviant workplace activities.
• Status inequities create frustration and can adversely influence productivity and the
willingness to remain with an organisation. Among individuals who are equity-sensitive,
incongruence is likely to lead to reduced motivation and an increased search for ways to
bring about fairness (that is, taking another job). In addition, because lower-status people
tend to participate less in group discussions, groups characterised by high status differences
among members are likely to inhibit input from the lower-status members and to
underperform their potential.
• Large groups are more effective at fact-finding activities, while smaller groups are more
effective at action-taking tasks. Social loafing knowledge suggests that measures of
individual performance are necessary if larger groups are used.
• Cohesiveness plays an important function in influencing a group’s level of productivity.
• High congruence between boss and employee as to the perception of the employee’s job
shows a significant association with high employee satisfaction. Role conflict is associated
with job induced tension and dissatisfaction.
• Decisions made by groups provide both advantages and disadvantages. •
o Advantages: Group inputs are more comprehensive and more accurate, with more
diverse viewpoints, leading to greater creativity; groups more readily agree on
decisions because of a larger involvement.
o Disadvantages: Decisions are slow and time consuming and build pressures for
conformity; this is especially apparent when a minority dominates the group.
Accountability is also ambiguous.
• Groups can suffer two afflictions:
o groupthink—where highly cohesive groups can diverge from acceptable social
norms; and
o groupshift—where stress is created due to the diverse levels of risk individuals will
tolerate within the group as the eventual level of risk is forced to conform to one
level.
• The shift from working alone to working on teams requires employees to cooperate with
others, share information, confront differences and sublimate personal interests for the greater
good of the team.
• Effective teams have been found to have a number of common characteristics: •
o They have adequate resources, effective leadership, a climate of trust, and a
performance evaluation and reward system that reflects team contributions.
o They are made up of individuals with technical expertise, as well as problem-solving,
decision-making and interpersonal skills; and high scores on the personality
characteristics of extraversion, agreeableness, conscientiousness and emotional
stability.
o They tend to be small—with fewer than ten people—preferably made up of
individuals with diverse backgrounds.
o They have members who fill role demands, are flexible and who prefer to be part of a
group. And the work that members do provides freedom and autonomy, the
opportunity to use different skills and talents, the ability to complete a whole and
identifiable task or product, and work that has a substantial impact on others.
o They have members who are committed to a common purpose, specific team goals,
belief in the team’s capabilities, a manageable level of conflict and a minimal degree
of social loafing.
o Because individualistic organisations and societies attract and reward individual
accomplishments, it is more difficult to create team players in these environments.
To make the conversion, management should try to select individuals with the
interpersonal skills to be effective team players, provide training to develop
teamwork skills, and reward individuals for cooperative efforts.

A Team Culture at Hilton
Felicia Liew is the HR director at the Hilton Hotel in Kuching, the capital of the East Malaysian state
of Sarawak, located on the island of Borneo. As a worldwide chain, senior management have the
challenge of guaranteeing the consistent service that customers expect. The hotel has adopted the
Balance Scorecard approach to performance management. Success is based on a team culture
committed to high quality service, a fun family-oriented atmosphere where positive attitudes and a
strong work ethic are rewarded.
Felicia provides a range of training programs for new recruits and existing staff. She deals with
various functional groups and the challenge is not only to develop the necessary skills but also get the
various functional groups to work as effective teams.

Learning from the Experience of Team Management
Glen Simpson is the chief executive of the development division of Coffee International, an
Australian-based engineering company with a number of specialised divisions. As with many global
companies, the challenge of working with and integrating the activities of a diverse range of groups in
different locations and cultures can be daunting.
Personal success needs to be seen in the context of teams and working with others for results. Glen
points out that it is a journey of self-understanding about what motivates and discourages people, and
that it is the simple things that count. Dr Neil Miller’s experience as managing director of Canberra-
based software and services supplier TASKey, realises the need to provide teams with effective
decision support systems so that all members of the team are constantly in touch with the projects they
are working on. TASKey’s real-time task and team management software grew out of Miller’s work
for a PhD on introducing change in organisations. He maintains that project management
methodologies are top-down, designed for the project manager, not the people involved. It’s not
collaborative. TASKey web-based software takes over the detailed management tasks, ensuring that
all team members immediately receive updates on critical project information.
Teaching Note: This article can be used as a guide to a mini research project or group discussion for
students. The vignettes from both managers indicate that collaborative processes are necessary for
many team situations, whereas traditional methodologies are appropriate for leader managed
interactions. How does the student’s experience of team based projects compare? What could be
done to better facilitate student collaborative projects?

‘Two Heads are Better Than One’
This statement is mostly true if “better” means that two people will come up with more original and
workable answerers to a problem than one person working alone.
The evidence generally confirms the superiority of groups over individuals in terms of decision-
making quality. Groups usually produce more and better solutions to problems than do individuals
working alone. The choices groups make will be more accurate and creative. Groups bring more
complete information and knowledge to a decision, so they generate more ideas. In addition, the
give-and-take that typically takes place in group decision processes provides diversity of opinion and
increases the likelihood that weak alternatives will be identified and abandoned.
Research indicates that certain conditions favour groups over individuals. They include: 1) Diversity
among members, 2) The group members must be able to communicate their ideas freely and openly,
and 3) The task being undertaken is complex. Relative to individuals, groups do better on complex,
rather than simple tasks.
Class Exercise:
1. This will require you to supply groups with Lego® blocks.
2. Create a simple model—a building, a plane, whatever—because you need to provide Lego to each
team and individual to recreate it. Three-to-eight sets.
3. Count the number of pieces of Lego, diagram the model, noting both the location, size, and colour
of the Lego. This will be your master.
4. Select two teams of three-to-five, and at least three individuals. The rest of the class will observe
and help you.
5. Give the groups and the individuals the same instructions on the exercise. Ask them to tell you
when they have completed the task.
6. Select one student to create a time chart on the board and record when each unit—group or
individual—begins to build and their completion time.
7. Select two students to be “certifiers”; they will go to the individual or team when they are done
and certify the accuracy of their model.
8. Select one student to monitor the model, which needs to be outside of the class, in another
location.
Instructions:
1. This is a timed exercise. They have 30 minutes. The goal is to recreate the model accurately and
quickly.
2. They must visit the model in another room. They may not touch it, but they may sketch it.
3. Teams may assign responsibilities any way they desire; all members may view the model, but only
one at a time.
4. Once they are ready to replicate the model they must notify you, and they may NOT return to the
model again.
5. They must build their replicates in your classroom and cannot take the Lego with them.
Discussion:
1. When you call time, some will be done, some will not, and some will be lost.
2. Discuss what type of task this was—complex or simple.
3. Note the performance, time, and accuracy.
4. Discuss with the class why things turned out as they did. What happened in the groups?
Note to instructor: Generally, teams will be more accurate but take more time. Sometimes, you will
get an individual with a photographic memory who will beat everyone.

POINT/COUNTERPOINT – All Jobs Should Be Designed Around Groups
POINT
Groups, not individuals, are the ideal building blocks for an organisation. There are at least six reasons
for designing all jobs around groups.
• Small groups are good for people. They can satisfy social needs and they can provide support
for employees in times of stress and crisis.
• Groups are good problem-finding tools. They are better than individuals in promoting
creativity and innovation.
• In a wide variety of decision situations, groups make better decisions than individuals do.
• Groups are very effective tools for implementation. Groups gain commitment from their
members so that group decisions are likely to be willingly and more successfully.
• Groups can control and discipline individual members in ways that are often extremely
difficult through impersonal quasi-legal disciplinary systems. Group norms are powerful
control devices.
• Groups are a means by which large organisations can fend off many of the negative effects of
increased size. Groups help to prevent communication lines from growing too long, the
hierarchy from growing too steep, and the individual from getting lost in the crowd.
Given the above argument for the value of group based job design, what would an organisation look
like that was truly designed around group functions? This might best be considered by merely taking
the things that organisations do with individuals and applying them to groups. Instead of hiring
individuals, they would hire groups. Similarly, they would train groups rather than individuals, pay
groups rather than individuals, promote groups rather than individuals, fire groups rather than
individuals, and so on.
The rapid growth of team-based organisations over the past decade suggests we may well be on our
way toward the day when almost all jobs are designed around groups.
COUNTERPOINT
Designing jobs around groups is consistent with an ideology that says that communal and socialistic
approaches are the best way to organise our society. This might have worked well in the former
Soviet Union or Eastern European countries, but capitalistic countries like Australia, New Zealand, the
United States, Canada and the United Kingdom value the individual. Designing jobs around groups is
inconsistent with the economic values of these countries. Moreover, as capitalism and
entrepreneurship have spread throughout Eastern Europe, we should expect to see less emphasis on
groups and more on the individual in workplaces throughout the world. Cultural and economic values
shape employee attitudes toward groups.
Capitalism was built on the ethic of the individual. Individualistic cultures such as Australia, New
Zealand, Canada and the Unites States strongly value individual achievement. They praise
competition. Even in team sports, they want to identify individuals for recognition. People from these
countries enjoy being part of a group in which they can maintain a strong individual identity. They
don’t enjoy sublimating their identity to that of the group.
The Western industrial worker likes a clear link between his or her individual effort and a visible
outcome. The United States, for example, has a considerably larger proportion of high achievers than
exists in most of the world. America breeds achievers, and achievers seek personal responsibility.
They would be frustrated in job situations in which their contribution is commingled and homogenised
with the contributions of others.
Western workers want to be hired, evaluated, and rewarded on their individual achievements. They
believe in an authority and status hierarchy. They accept a system in which there are bosses and
Instructor’s Manual: Robbins Organisational Behaviour 5e © 2008 Pearson Education Australia 9-17
subordinates. They are not likely to accept a group’s decision on such issues as their job assignments
and wage increases. It is harder yet to imagine that they would be comfortable in a system in which
the sole basis for their promotion or termination would be the performance of their group.
Based on H. J. Leavitt, “Suppose We Took Groups Seriously,” in E. L. Cass and F. G. Zimmer (eds.),
Man and Work in Society (New York: Van Nostrand Reinhold, 1975), pp. 67–77.
Class Exercise:
1. Discuss group versus individual grading with students.
2. Begin by polling them as to whether they would prefer a grade for this class (or another specific
class) based on their individual effort or on the effort of a five-student group they belonged to. The
class mix on this issue will vary.
3. Move the group-based grade students into groups; leave the individual-based grade students. Have
them create a list of three-to-five of the reasons for their preference.
4. After 10–15 minutes, have the group-based students pick a spokesperson and have them record
their lists of the board. Once they are recorded, start an “individual” list by asking the individual
students, one at a time, for a reason, going round robin until you have all of their responses.
5. Now, as a class, compare and discuss the reasons. How are the lists different? The same? Is there a
theme or themes emerging (groups—safety in numbers, it is a hard class; individual—I want
control of my grade, etc.).
6. Ask students if they think the reasons that seem to be emerging would:
• Be acceptable to other students in other classes in your school
• Be acceptable to other students when it came time to interview for jobs
• A way to get ahead in their careers (group effort rather than individual effort being rewarded)
Instructor’s Manual: Robbins Organisational Behaviour 5e © 2008 Pearson Education Australia 9-18
who will control the group and when complete, there will be a relatively clear hierarchy of leadership
within the group.
• The third stage is norming. Characterised by close relationships developing and the group
demonstrates cohesiveness. There is now a strong sense of group identity and camaraderie. The
stage is complete when the group structure solidifies and the group has assimilated a common set of
expectations of what defines correct member behaviour.
• The fourth stage is performing. The structure at this point is fully functional and accepted.
Group energy has moved from getting to know and understand each other to performing.
• The fifth stage is Adjourning. Relevant for temporary committees, teams, task forces, and
similar groups that have a limited task to perform. In this stage, the group prepares for its
disbandment. Attention is directed toward wrapping up activities. Responses of group members
vary in this stage. Some are upbeat, basking in the group’s accomplishments. Others may be
depressed over the loss of camaraderie and friendships.
Status derived from one of three sources: the power a person wields over others; a person’s ability
to contribute to group’s goals; individual’s personal characteristics.
• People who control the outcomes of a group through their power tend to be perceived as high
in status (e.g., a group’s formal leader or manager).
• People whose contributions are critical to the group’s success also tend to have high status
(e.g., outstanding performers on sports teams).
• Someone who has personal characteristics that are positively valued by the group (such as
good looks, intelligence, money or a friendly personality) will typically have higher status
than someone who has fewer valued attributes.
7. List and describe the process variables associated with effective team performance.
Answer - These include member commitment to a common purpose, establishment of specific team
goals, team efficacy, a managed level of conflict, and minimising social loafing.
• A common purpose - Effective teams have a common and meaningful purpose that provides
direction, momentum, and commitment for members. This purpose is a vision. It is broader than
specific goals.
• Specific goals - Successful teams translate their common purpose into specific, measurable, and
realistic performance goals. Specific goals facilitate clear communication and help teams maintain
their focus on results. Team goals should be challenging.
• Team efficacy - Effective teams have confidence in themselves and believe they can succeed—
this is team efficacy. Success breeds success. Management can increase team efficacy by helping the
team to achieve small successes and skill training. Small successes build team confidence. The
Instructor’s Manual: Robbins Organisational Behaviour 5e © 2008 Pearson Education Australia 9-19
greater the abilities of team members, the greater the likelihood that the team will develop confidence
and the capability to deliver on that confidence.
• Conflict levels - Conflict on a team is not necessarily bad. Teams that are completely void of
conflict are likely to become apathetic and stagnant. Relationship conflicts—those based on
interpersonal incompatibilities, tension, and animosity toward others—are almost always
dysfunctional. On teams performing non-routine activities, disagreements among members about task
content (called task conflicts) is not detrimental. It is often beneficial because it lessens the likelihood
of groupthink. Effective teams will be characterised by an appropriate level of conflict.
• Social loafing - Individuals can hide inside a group. Effective teams undermine this tendency by
holding themselves accountable at both the individual and team level.
In studies of historic American foreign policy decisions, these symptoms were found to prevail when
government policy-making groups failed. Groupthink appears to be closely aligned with the
conclusions Asch drew from his experiments. Groupthink does not attack all groups. It occurs most
often where there is a clear group identity, where members hold a positive image of their group
which they want to protect, and where the group perceives a collective threat to this positive image.
1. Identify five roles you play. What behaviours do they require? Are any of these roles in conflict?
If so, in what way? How do you resolve these conflicts?
Answer – Students’ answers will vary. Some suggested roles: student, sibling, child, adult, group
leader, member of a social group, etc. Behaviours and conflicts will vary with role.
2. “High cohesiveness in a group leads to higher group productivity.” Do you agree or disagree?
Explain.
Answer – Groups differ in their cohesiveness—the degree to which members are attracted to each
other and are motivated to stay in the group. Cohesiveness is important because it has been found to
be related to the group’s productivity. The relationship of cohesiveness and productivity depends on
the performance-related norms established by the group. If performance-related norms are high, a
cohesive group will be more productive, but if cohesiveness is high and performance norms are low,
productivity will be low. Students’ responses will vary based on their perception and integration of
the above facts.
4. What effect, if any, do you expect that workforce diversity has on performance and satisfaction?
Instructor’s Manual: Robbins Organisational Behaviour 5e © 2008 Pearson Education Australia 9-20
Answer – Research studies generally substantiate that heterogeneous groups—those composed of
dissimilar individuals—are more likely to have diverse abilities and information and should be more
effective, especially on cognitive, creativity-demanding tasks. The group may be more conflict
laden and less expedient.
Essentially, diversity promotes conflict, which stimulates creativity, which leads to improved
decision making. Diversity created by racial or national differences interfere with group processes,
at least in the short term. Cultural diversity seems to be an asset on tasks that call for a variety of
viewpoints. Such groups have more difficulty in learning to work with each other and solving
problems. These difficulties seem to dissipate with time as it takes time for diverse groups to learn
how to work through disagreements and different approaches to solving problems.
5. If you need to generate a lot of ideas in a short period of time, would you have a bunch of
individuals generate ideas on their own, or would you band them together in groups?
Answer – Students’ responses will vary. Generally, students should indicate that group based
brainstorming would be the preferred technique in this case. They may also discuss the nominal
group technique or other methods discussed in the text.
Suicide bombers and terrorist attaches have been commonplace for decades in much of the Middle
East. But not so for Australasia and North America. The attacks on 11 September, 2001, opened
North American eyes to the reality that no place is completely safe from terrorist attacks. Australians
were shocked by the Bali bombings and a range of other bombings around the world. A number of
Australians and Americas allowed the actions of a few Muslim extremists to shape their attitudes
towards all Muslims. The result has created challenges for managers leading diverse groups contain
members of Middle Eastern backgrounds.
Jeff O’Connell is one of those managers. Jeff oversees a team of five computer chip designers,
working exclusively on defence contracts; the team comprises a women from Texas, an African
American from New York, two Russians, and an Arab American born in California to parents who
emigrated from Iran. Jeff, himself, was born in Canada, but raised in the United States. In the months
following the 11 September attacks and again following other publicised terrorist attacks Jeff became
aware that several of his team members were making openly disparaging remarks to Nicholas, their
Iranian co-worker, questioning his Arab friends, his religious practices and his loyalty to America.
Nicholas’s colleagues understood little about Islam and Nicholas’s religious practices. What, if
anything, should he do when he sees team members discriminating against Nicholas because of his
ethnicity?
Class discussion
1. In small break-out groups – where possible create groups with a maximum diversity of age,
gender, and ethnicity.
2. Ask the groups to reflect upon the situation in the case. Ask whether anyone in the group has
experienced discrimination because of their race, gender, ethnicity, group membership etc.
What was the situation and how did it make them feel? What solutions were sought to remove
the discrimination?
3. Returning to the case, ask the small groups to identify a number of recommendations for Jeff
and to record their suggestions for later discussion in the large group.
4. Returning to the large group – combine the suggestions that the smaller groups have
identified for Jeff.
5. Then lead a group debrief regarding the ranges of experiences that students in the group have
offered for discussion.

CASE STUDY 7 – The Dangers of Groupthink
Sometimes, the desire to maintain group harmony overrides the importance of making sound
decisions. When that occurs, team members are said to engage in groupthink.
• A civilian member of a process improvement team formed to develop a better way to handle
an air force bases mail took almost one month to come up with a plan. The problem – the
plan wasn’t a process improvement – 8 steps were now 19. The team’s new plan slowed mail
considerably – even though members new the plan was worse than its predecessor no one
wanted to question the team’s solidarity.
• During the dot.com boom Virginia Turezyn was victim of groupthink. Although sceptical of
the stability of the boom, after continually reading about the start-ups turning into
multimillion-dollar payoffs, she felt different, investing millions in several dot.com’s
including I-drive, a company providing electronic data storage. The problem was I-drive was
giving storage away for free and the company was losing money. She spoke up at one board
meeting, but the other younger executives disagreed. Turezyn began to question herself
thinking that she was too old and didn’t understand it. Unfortunately she did get it and the
company later filed for bankruptcy.
• Steve Blank, entrepreneur, also fell victim to groupthink. Also involved in dot.com start-up
he tried to persuade fellow board members to move to a more traditional business model. The
team didn’t take Blank’s advice, and he lost hundreds of thousands of dollars on the deal.
Questions
1. What are some of the factors that led to groupthink in the above cases? What can teams do to
attempt to reduce groupthink from occurring?
Answer - group size, status differences, norms, cohesion, decision making techniques
2. How might differences in status among group members contribute to groupthink? For example,
how might lower-status members react to a group’s decision? Are lower-status members more or less
likely to be dissenters? Why might higher-status group members be more effective dissenters?
Answer - The mail process improvement suffered from group status differences, with civilian lower-
status people in the group unwilling to challenge the security of the group identity with challenges to
the decisions. Having someone (even on a rotating basis) become the devil’s advocate would have
given the opportunity for dissenting voices to be heard.
3. How do group norms contribute to groupthink? Could group norms guard against occurrence of
groupthink? As a manager, how would you try to cultivate norms that prevent groupthink?
Answer – Group norms control the behaviour of group members. Members are motivated to
conform to group behavioural expectations in order to remain members of the group.
Implement some of the strategies suggested earlier, ie., monitor group size – people grow
more intimated and hesitant as group size increases, encourage group leaders to play an
impartial role, appoint one group member to play the role of devil’s advocate, utilise exercises
that stimulate active discussion of diverse alternatives without threatening the group and
intensifying identity protection.
4. How might group characteristics such as size and cohesiveness affect groupthink?
Answer - Groupthink appears to be closely aligned with the conclusions Asch drew from his
experiments on the lone dissenter. The results where individuals who hold a position different
from the majority are put under pressure to suppress or change their true beliefs. Groupthink
does not attack all groups. It occurs most often where there is a clear group identity, where
Instructor’s Manual: Robbins Organisational Behaviour 5e © 2008 Pearson Education Australia 9-22
members hold a positive image of their group which they want to protect, and where the
group perceives a collective threat to this positive image.

THE TURQUOISE.
There are few gems more commonly seen on jewelry than the blue
turquoise. Its beauty, its serviceable hardness, its pleasing contrast
with gold, and its moderate price, explain why it is so much
esteemed. Only a few exceptionally fine specimens of the stone rank
with the ‘rich and rare’ gems. In the unlikely event of Persia being at
war with all the rest of the world, it would, no doubt, become scarce
and dear outside the dominion of the Shah, since it is only in that
country that the mineral in a state fit for the jeweller’s purpose is
found. Much and widely as the turquoise is used for personal
ornaments, the supply has for some time considerably exceeded the
demand except for fine stones of an uncommon size. But, as is the
case with all precious stones, unusually large pieces—those
approaching the size of a hazel nut, for example—when of good
quality, are eagerly sought after, and have a high intrinsic value.
The turquoise has in all likelihood been used as a gem from a very
remote antiquity, since the range of mountains where it is plentifully
found is situated at no great distance from the southern shore of the
Caspian Sea, near to, if not within, the area believed by many to
have been the cradle of the human race. By some scholars, it is
thought highly probable that the turquoise was used for inlaying the
delicate and beautiful gold-work of ancient Greece; and at all events,
there is a cameo portrait of a classic Greek prince in this mineral
among the specimens in the famous collection of Marlborough gems.
There is some doubt about the name this precious stone was known
by in Pliny’s time. He mentions that the callais, which was probably
the turquoise, was found in Asia, where it occurred projecting from
the surface of inaccessible rocks, whence it was obtained by means
of slings; but these were the days of fables. That it was known to the
ancient Romans is, however, proved by the fact that there still exist
some, though only a very few, of their works of art cut in this mineral.
Want of certainty about the name applied to the turquoise in classic
times leaves us in doubt as to what mystic virtues were then
attributed to it. But in the middle ages, the turquoise, like other gems,
was believed to have wonderful properties; indeed, it was credited
with more supernatural virtues than most of them. The wearer of it
had both his sight strengthened and his spirits cheered; he enjoyed
immunity from the consequences of a fall by the gem itself breaking,
in order to save his bones; and his turquoise, like himself, turned
pale if he became sick. When its possessor died, it entirely lost its
colour; but recovered it again on passing into the hands of a new
owner. In some mysterious way, when suspended by a string, it
correctly struck the hours on the inside of a glass vessel. Other
precious stones have lost all the marvellous powers that belonged to
them for centuries: the emerald no longer relieves the fatigued
eyesight; the diamond cannot now dispel fear; the sapphire, though
still cold to the touch, has ceased to be able to extinguish fire. In
these perverse days, the hailstorm comes down even upon the
wearer of an amethyst, and bright red coral attracts rather than
repels robbers. But the turquoise still retains one of its mysterious
properties, and flaunts it in the face of modern science. Sometimes
slowly, sometimes suddenly, it unaccountably turns pale, becomes
spotted, or changes from blue to white; and specimens that behave
in this capricious manner are found more commonly than those
whose colour is distinctly permanent.
The turquoise is called in chemical language a hydrated phosphate
of alumina. This means that it consists mainly of phosphoric acid and
alumina, along with nearly twenty per cent. of water. It owes its
colour to small quantities of compounds of copper and iron. It occurs
blue, green, and bluish green; but the change to a pale, mottled, or
white colour, which inferior turquoises undergo, generally takes place
soon after they are taken from the mine. These colours are opaque,
or only very slightly translucent, and the stone has a somewhat waxy
lustre. It is only those of a fast ‘sky-blue’ colour that are prized for
jewelry; but at one time, a green turquoise was more highly valued
than a blue one. Nowadays, however, people have no patience with
either precious stones or precious metals that can be easily
mistaken for those of inferior value. Either green felspar, which is of
the same hardness, or malachite, which is softer, might be mistaken
for green turquoise, and both are more common minerals. But there
is hardly any other natural stone of the same, or even inferior,
hardness that can be confounded with a blue turquoise. The material
of some fossil teeth when coloured with phosphate of iron does,
however, resemble it. Still, there need be no confusion, because this
substance is softer. It is called odontolite or occidental turquoise;
while the real stone is known by jewellers as the oriental turquoise.
Odontolite is easily recognised under the microscope by the
characteristic markings of dentine. Opaque blue glass can be made
to imitate the turquoise; but the former differs in lustre and in the
nature of its fracture.
Turquoises are found in Tibet, China, and the neighbourhood of
Mount Sinai; but, as has been already stated, the supply for
jewellers’ purposes comes almost wholly from the celebrated
Persian mines. Very little was known about these till a remarkably
interesting and exhaustive Report upon them was recently furnished
to the British Foreign Office by Mr A. Hontum Schindler, who was for
a short time Director of the mines. They are situated in a range of
mountains bounding on the north an open plain in the Bâr-i-Madèn
district, thirty-two miles north-west of Nishâpûr, in the province of
Khorassan. Botanists tell us that the brightest blue is seen on alpine
flowers. If pure mountain air could be supposed to brighten the
colour of a gem as well as a flower, there is no want of it where these
turquoise veins occur. Their position is between five and six
thousand feet above the level of the sea, and a strong north wind
blows almost continually over the ridges of the hills, rendering the
situation very healthy. Wheat, barley, and mulberry trees grow well
on the slopes at the lower of these heights.
Geologically, the mountains are composed of sandstones and
nummulitic limestones lying on clay-slates and inclosing immense
beds of gypsum and rock-salt. But these stratified rocks are broken
through and metamorphosed by rocks of igneous origin, such as
greenstones and porphyries. The turquoise-bearing veins occur in
the metamorphic strata, and the mines proper consist of shafts and
galleries in the solid rock. There are also ‘diggings’ in the detritus of
disintegrated rock washed down towards the plain, and it is here that
some of the best turquoises are found. A number of the mines are
ancient and very extensive; and although most of them are now
more or less in a state of neglect, Mr Schindler states that the
presence of many old shafts—now filled up—for light and ventilation
proves that they have at one time been skilfully worked, and were
probably then under government control. But they appear to have
been, for nearly two centuries, farmed by the villagers, who only
think of a quick return for their money, and therefore cut away the
rock wherever they see turquoises, without leaving proper supports
to prevent the falling in of the mine. Several labourers have at
different times been buried in the galleries through the rubbish being
badly propped up. The perpendicular depth of one mine is one
hundred and sixty feet, and others are nearly as deep. The miners
work with picks and crowbars in much the same way as that in which
vein-mining is carried on elsewhere; and it is a curious illustration of
how slowly long-established processes are altered in the East, that
gunpowder should have been used in these mines only within the
last thirty years. But it is not strange, as can be seen by some
examples of rock-blasting at home, to learn that the results obtained
by gunpowder are, in one view, less satisfactory than those got by
the pick. The powder does more work, but it is also more destructive,
as it breaks the turquoises into small pieces.
Here we may say a few words about how it fares with the people
who are occupied with the mining, cutting, and selling of the
turquoises. About two hundred men work in the mines or at the
diggings, and some thirty more—elders of the village—buy the
turquoises and sell them to merchants and jewellers. A certain
additional number of hands cut and polish the stones; but this work
is done elsewhere, as well as in the district where they are found.
The population of the villages in the neighbourhood of the mines is
about twelve hundred, and the inhabitants, as in most mining
districts, are improvident. Nearly all the men, and not a few of the
women, are inveterate opium-smokers. Agriculture is neglected.
Turquoise-dealing and its gains make the people careless of
anything else. As a rule, the money is quickly spent; and men who
easily earn a sum fully equal to fifty pounds sterling per annum, have
often nothing to eat.
At the mines, the turquoises are roughly divided into three classes,
of first, second, and third qualities. All the stones of good and fast
colour and favourable shape belong to the first class. But how
curiously these vary in value will be best understood by quoting Mr
Schindler’s own words: ‘It is impossible to fix any price, or classify
them according to different qualities. I have not yet seen two stones
alike. A stone two-thirds of an inch in length, two-fifths of an inch in
width, and about half an inch in thickness, cut peikâni (conical)
shape, was valued at Meshed at three hundred pounds; another, of
about the same size, shape, and cut, was valued at only eighty
pounds. Turquoises of the size of a pea are sometimes sold for eight
pounds. The colour most prized is the deep blue of the sky. A small
speck of a lighter colour, which only connoisseurs can distinguish, or
an almost unappreciable tinge of green, decreases the value
considerably. Then there is that undefinable property of a good
turquoise, the zât, something like the “water” of a diamond or the
lustre of a pearl; a fine coloured turquoise without the zât is not worth
much.’ He subsequently adds: ‘The above-mentioned three hundred
pounds Meshed turquoise was bought from the finder by one of the
Rish-i-Safîds (elders of the village) for three pounds; the latter sold it
still uncut at Meshed for thirty-eight pounds. As soon as it was cut,
its true value became apparent, and it was sent to Paris, where it
was valued at six hundred pounds. The second purchaser, however,
received only three hundred and forty pounds for it; the difference
was gained by the agents.’ Among the fine turquoises in the
possession of the Shah, there is one valued at two thousand
pounds.
The best stones of the second class are worth about ninety pounds
per pound; whilst the most inferior will scarcely bring a twentieth part
of this price. The latter are chiefly used in Persia for the decoration of
swords, horse-trappings, pipe-heads, and the common kinds of
jewelry. Small cut turquoises of a slightly better quality than these
sell at the rate of from two to three shillings per thousand. In the third
class are included stones unsaleable in Persia, as well as large flat
stones, some of which are esteemed for amulets, brooches, buckles,
and the like. The prices given there will be more than doubled when
the turquoises are sold in Europe.
The turquoise being an opaque stone, it would be useless to cut
facets upon it, as these would not reflect light in the same way as
when fashioned upon a transparent gem like a diamond or a
sapphire. There are three ways of cutting the turquoise, all much in
the same style—the flat or slightly convex form, the truncated cone,
and the tallow drop or en cabochon. The higher the conical and
convex surfaces in the two latter, the more the turquoises are prized.
None but a fine deep-coloured stone can be advantageously cut into
a conical shape, since one of pale colour would appear almost white
at the apex. Turquoises are cut by the hand on wheels made of a
composition of emery and gum. They are afterwards polished by
being rubbed on a fine-grained sandstone, and then on a piece of
soft leather with turquoise dust.
Of the few mines which yield good turquoises, one or two are
dangerous, on account of the loose rubbish they contain. The one
from which the best of all are obtained yields very few. Some mines
contain stones which look well at first, but soon change their colour
and fade. Mr Schindler gives an instance of a recently found
turquoise, as large as a walnut and of fine colour, being presented to
His Majesty the Shah, which he had for only two days, when it
became green and whitish, and therefore of no value. Throughout
Europe, there has been a great fall in the price of this gem within the
last few years, and it would seem that this is owing to the fact that
large quantities of stones which appeared to be of fine quality, but
were really of fugitive colour, had been disposed of not long ago at
good prices. Up to the time that they were sold, their colour had
been preserved by keeping them damp; but when taken out of their
moist packing, they slowly became white. It need hardly be said that
the colour of most precious stones is very permanent. There is,
however, a variety of opal occurring in Mexico which is very beautiful
when first found; but after a brief time it entirely loses its bright play
of colours. Both the turquoise and the opal are peculiar in containing
a considerable amount of water in their composition.
The colour of a fine turquoise has not escaped the notice of
enamellers and potters. For centuries, an imitation of its
characteristic and lovely blue has been applied among other colours
to the exquisitely decorated pottery of Persia. On the most expensive
and perhaps also the most beautiful of all porcelain, the Sèvres ware
of soft body made in the latter half of last century, the turquoise blue
is often a conspicuous colour. Towards the end of the century, when
the directors of the far-famed fabrique changed the character of the
china to that of a hard paste or body, its decoration with a turquoise
colour was no longer possible. But modern English porcelain, like the
old Sèvres, is of soft paste; and one of the feats on which our great
Staffordshire potters pride themselves is the successful production
upon it, in recent years, of a soft and clear turquoise blue.
