Case 10-1
You are the manager of the internal audit of a savings and loan association that has decided to install a bill payment by telephone system for its customers. The system will allow customers to telephone a number to enter the system, record bill payment transactions they wish to make within the next 30 days, and transfer funds between savings and checking accounts. A voice feedback system will instruct customers on how to complete each step of a transaction; for example, record the date of a payment and the amount to be paid. Note, all data is to be entered using a Touch-Tone telephone.
