Most commissioning engineers observe the testing in a passive way, and at the end of the test, they ask for the commissioning reports by the contractors. In their preprepared reports, you will never find a hick up or any failure noted. So, why bother having the reports, when everything is 100% perfect. In fact their reports are already done before they even start testing. Everything is Yes, Yes, OK, OK! There are tests that indeed go smoothly. Faults do happen and often due to multiple reasons that can be either fixed quickly or postponed and fixed later. That has to be recorded, as well as all the temporary deviations due to missing components, etc.

We do our own commissioning or precommissioning report for reasons noted below. We do it directly on our PCs as the events evolve. We sit with the test engineers at the end of a large desk in front of the main control panel and observe and write:

 We do not make a story. We write the action.

 The testers pay more attention to their work in our presence. They cannot hide the actual facts.

 As active people, we can ask for repeat tests or test it from a different perspective or condition.

 Our report is chronological and timed as it happens. One never knows what and when something unusual will happen. It does happen and often. One wants to capture the moment and to include all the background details on what was in action before the occurrences of a failure.

 It includes the failures as a record, why and how they were resolved and made to be OK.

 Later on during the operation when something fails, one can look into the commissioning reports and figure out if this is a recurrence of the same fault and likely to be expected to happen again.
