After an information system has been installed and is in use, what is the term for the post-implementation appraisal that evaluates performance, benefits, and lessons learned?

Introduction / Context:
Project success is not fully known until the system runs in production. A structured post-implementation evaluation checks whether objectives were met, users are satisfied, controls are effective, and value is realized. This feedback informs optimization and future projects.

Given Data / Assumptions:

• The system has been deployed and stabilized.
• Stakeholders can report on usability, performance, and outcomes.
• Metrics and KPIs were defined during planning to measure success.

Concept / Approach:

A post-implementation review (sometimes called PIR) evaluates benefits realization, cost variances, incident patterns, and user adoption. Maintenance is the ongoing process of changes and fixes; planning and batch processing are unrelated to the appraisal activity itself.

Step-by-Step Solution:

Verification / Alternative check:

Governance frameworks (e.g., PRINCE2, PMBOK) require post-project reviews to capture lessons learned and benefits realization.

Why Other Options Are Wrong:

Maintenance: Execution of updates, not evaluation.

Planning/Batch processing: Different lifecycle activities.

None: Incorrect because “review” is the standard term.

Common Pitfalls:

Skipping the review leads to repeated mistakes and unverified benefits in subsequent initiatives.

Final Answer:
