What Activity Ensures Effective Post-Implementation Reviews?

CRISC By islever Editorial Last updated

Short answer

B Allow a sufficient number of business cycles to be executed in the new system

Question

What activity should be done for effective post-implementation reviews during the project?
  1. Establish the business measurements up front
  2. Allow a sufficient number of business cycles to be executed in the new system Correct Answer
  3. Identify the information collected during each stage of the project
  4. Identify the information to be reviewed

Key Takeaways

This question tests the timing and data requirements for post-implementation reviews, where test-takers frequently confuse upfront planning activities with execution-phase validation steps.

Effective post-implementation reviews require allowing sufficient business cycles to execute within the new system before evaluation. The CRISC community consistently emphasizes that real-world operational data is mandatory for validating controls and project benefits.

Common mistake: Option A is commonly chosen because defining business measurements is critical, but it belongs to the project initiation phase rather than the post-implementation review period.

Expert Analysis

Why the Answer Is Correct

Allowing a sufficient number of business cycles to run ensures that the new system processes real transactions under normal operating conditions. Post-implementation reviews rely on empirical evidence to determine whether implemented controls function as designed and whether projected benefits are realized. Without actual cycle data, evaluators cannot accurately measure performance, identify residual risks, or validate return on investment. ISACA guidelines stress that meaningful reviews must be grounded in observed operational behavior rather than theoretical projections.

Why the Other Options Are Wrong

Option A describes a proactive planning step that must occur during project initiation, not during or after implementation. Option C focuses on continuous monitoring throughout development, which does not specifically address the retrospective validation required for a post-implementation review. Option D involves scoping the review process itself, which is administrative preparation rather than the substantive activity needed to generate valid review data. Each distractor misplaces the timing or confuses preparatory tasks with execution-phase requirements.

Community Comment Notes

Multiple users highlight that business cycles must complete to gather actionable data before conducting a review. Comment [1] and Comment [3] both reinforce that executing full operational cycles is necessary to collect accurate lessons learned and verify system functionality. Comment [2] correctly points out that establishing measurements upfront precedes the review phase, eliminating Option A. The unanimous community agreement aligns with ISACA’s emphasis on data-driven validation during project closure.

Exam Strategy

Always map answer choices to the specific project lifecycle phase mentioned in the question stem to avoid timing traps. When evaluating post-implementation or audit scenarios, prioritize options that involve actual data collection and real-world testing over theoretical planning or documentation steps.

    The answer is B for proper post implementation review and collected lesson learned

    Should be B, how can you just move on to other steps without confirming if your finish product is working as designed, after a few runs then collect data.

    business measurement front up but happens before PIR, not during it.
