Question 1

Central Bank of XYZ has announced the introduction of Malaysia's new currency series that will be
available in the January 2022. The new banknotes issued are in the denominations of RM30 and
RM60. Therefore, all banks will be affected by the new currency series announced by the central
bank.

ABC bank is the largest banks in Malaysia. It has 200 branches. ABC bank provides a variety of
banking services to their customers. Currently, due to the new direction from central bank, there are
some problems and challenges faced by ABC such as dispensing and depositing new notes by
Automated Teller Machine (ATM)/Cash Deposit Machine (CDM).

At the same time, IT manager in ABC bank has suggested to top management regarding the linkage of
debit card and Touch ‘n Go services. With this, customers are able to use their debit card to perform
cashless payment. Furthermore, they found out that their competitors are also offering such services to
provide more convenience to their customers.

In preliminary investigation, Mr. John, a systems analyst from ABC’s IT department has been
assigned to carry out the system analysis activity. The objectives of this system are to meet the new
requirements from central bank and also provide convenience to their customers using debit card for
payment. In addition, Miss Michelle, the head of system users’ department hopes that this new system
feature will be able to generate some reports to hasten her decision-making process.

NOTE: Based on the above case study to answer all the questions accordingly.

a) Explain THREE (3) sources of system request. (9 marks)

b) Explain why Preliminary Investigation is needed. (3 marks)

c) Illustrate ONE (1) possible technical issue, ONE (1) possible social issue and ONE (1) possible
economic issue which must be considered for the new system implementation. (9 marks)

d) Explain ONE (1) possible tangible benefit and ONE (1) possible intangible benefit of the new
system. (4 marks)

[Total: 25 marks]

Question 2 (Continued)

b) The following is the brief process of cashless payment using debit card:

When a customer uses his/her debit card to make cashless payment through TnG services at
point of sales terminal, he/she is required to insert the debit card and select TnG payment
option. The system will verify the debit card details and check the TnG balance from the
customer’s file. The payment is accepted when there is sufficient fund in TnG balance. The
