Who is responsible for Acceptance Phase Implement FPTs?

• A. Shared
• B. CxA
• C. CxT
• D. CxP

Answer: (A)

In the Acceptance Phase, Functional Performance Tests are a collaborative effort between the on-site team and the commissioning authority. The CxA designs and approves the FPT plan and acceptance criteria, sets what success looks like, and ensures the tests align with the project requirements. But the actual running of the tests, collecting data, making on-site adjustments, and confirming results are feasible during real operation is carried out by the team implementing the systems on site. That means the hands-on execution comes from the field personnel (the testing/installation crew) with support from the commissioning practitioner and technician as needed, under the CxA’s oversight. Because this work relies on both planning and practical execution across roles, responsibility is shared rather than assigned to a single party.
