Certified Information Systems Auditor (CISA) — Question 31

Which of the following is the BEST point in time to conduct a post-implementation review (PIR)?

Answer options

• A. To coincide with the annual PIR cycle
• B. Immediately after deployment
• C. After a full processing cycle
• D. Six weeks after deployment

Correct answer: C

Explanation

The best time to conduct a post-implementation review is after a full processing cycle as it allows for adequate evaluation of the system's performance over time. Conducting it immediately after deployment (B) may not provide enough data, while aligning with the annual cycle (A) or waiting six weeks (D) may miss critical insights gained during a complete processing period.
