Question 4 a. Fortune Ltd recently implemented an ERP. The IT auditor observes the following issues in the post- implementation review of the ERP: 1. Many department heads do not act on some reports during peak periods. They just put aside these reports in the hope of catching up at the off-peak time. 2. Some departments have so many reports that they do not act at all on the information, or they make incorrect decisions because of misuse of information. 3. Departments do not have a priority system for acting on the information produced by the ERP. Departments take actions only when the department heads are reminded by someone who needs the decision. 4. Department heads develop the information they need from alternative, independent sources rather than the ERP reports. The department heads claim that it is easier than trying to look for the data from the ERP reports. Suppose you are the IT auditor. Recommend procedures to Fortune Ltd to eliminate dysfunctional behaviours and to prevent their recurrence. (Please answer in details) b. Suppose you are the accountant of Supreme Ltd. Yesterday, your company completed the migration from an old accounting information to an ERP. The CEO of your company has insisted on running the old and new systems in parallel for an entire financial year. Try to convince the CEO that a year of running a system in parallel is too long. Suggest a way to end the dual systems while providing enough reassurance to the CEO. (Please answer in details)
