During the Acceptance Phase, who conducts Direct Re-Testing?

• A. Internal Team
• B. Shared
• C. CxT
• D. CxA

Answer: (D)

Direct Re-Testing during the Acceptance Phase is led by the CxA. The Acceptance Phase is about verifying that systems operate according to the design and that any issues fixed earlier actually meet the required performance. The Direct Re-Testing is a formal verification step specifically conducted under the Commissioning Authority’s oversight to confirm that remedies were effective and that the system now satisfies the acceptance criteria before final sign-off. The CxA maintains objective accountability and provides the official acceptance decision. The CxT may assist with testing tasks under direction, and the internal team can participate, but the responsibility for conducting Direct Re-Testing for acceptance rests with the CxA.
