In which phase are deficiencies corrected, and re-testing carried out?

• A. Post-Acceptance
• B. Design
• C. Acceptance
• D. Construction

Answer: (A)

The main idea is that fixing deficiencies and repeating tests happens after the initial acceptance activities, in the post-acceptance phase. When deficiencies are found during testing or acceptance, the team implements corrective actions, and then re-testing is performed to verify that those fixes actually resolve the issues and that the system meets the required performance criteria. This sequencing helps ensure that, before final handover or occupancy, every deficiency has been addressed and validated. Design and construction are where the plan and installation happen, while acceptance checks whether performance criteria are met; post-acceptance is the phase dedicated to closing out items found in earlier phases by correcting them and confirming through re-testing.
