Exam CISA topic 1 question 410 discussion

i think C- after a full processing cycle would be a better answer.

While conducting a PIR six weeks after deployment (Option D) may provide some initial insights into the immediate performance and stability of the implemented changes, it may not capture the full range of system usage and effects over time. Waiting for a full processing cycle allows for a more comprehensive and meaningful review of the implementation's success and its alignment with organizational objectives.

Answer: D Ref CISA RM 27th edition - 3.8 Post-implementation review Page: 171 (In contrast to project closure, a post-implementation review typically is carried out in several weeks or months after project completion)

Conducting a PIR after a full processing cycle allows for a comprehensive assessment of the system's performance and effectiveness in handling real-world data and transactions. This approach ensures that the review captures a complete picture of the system's functionality, identifies any issues or challenges encountered during regular operations, and evaluates the system's ability to meet business requirements over time.

C. After a full processing cycle. Conducting a PIR after a full processing cycle allows for a comprehensive assessment of the new system's performance, stability, and its impact on regular operations. This timing ensures that any issues or anomalies that might not have been apparent during initial deployment or immediately afterward can be identified and addressed. It provides a more accurate representation of the system's functionality and performance under typical working conditions.

Six week? How to measure if super big project, it difficult to said

The perfect time to conduct a PIR is between 2 to 6 weeks after project completion. This gives the project enough time to be in use, yet, still fresh in the users' minds.

PIR is done 2 to 6 weeks after implementation

The BEST point in time to conduct a post-implementation review (PIR) is "After a full processing cycle." This allows the system to be tested in a real-world scenario, and any issues can be addressed in a timely manner.
