What is NOT a component of the post-acceptance phase during commissioning?

The post-acceptance phase during commissioning focuses on various critical activities that ensure a project runs smoothly and continues to meet its intended performance levels after initial acceptance. In this context, baseline performance documentation plays a vital role. It involves documenting the initial performance metrics of the systems or processes to provide a reference point for future evaluations. This documentation helps in identifying any deviations from expected performance over time and ensures that any necessary corrective actions can be taken.

While personnel training, implementation of change control procedures, and document storage and modifications are all essential components of the post-acceptance phase, baseline performance documentation stands out as it provides the foundational metrics against which the systems will be assessed. Therefore, it is crucial for ongoing compliance and operational effectiveness, which is why it is included in the post-acceptance activities rather than excluded from them.
