Business units are concerned about the performance of a newly implemented system. Which of the following should an IS auditor recommend?

A. Develop a baseline and monitor system usage.

B. Define alternate processing procedures.

C. Prepare the maintenance manual.

D. implement the changes users have suggested.

Explanation:

An IS auditor should recommend the development of a performance baseline and monitor the systems performance, against the baseline, to develop empirical data upon which decisions for modifying the system can be made. Alternate processing procedures and a maintenance manual will not alter a systems performance. Implementing changes without knowledge of the cause(s) for the perceived poor performance may not result in a more efficient system.
