What separates a commissioning lead from a strong tester?

An engineer may perform a script, lead one discipline, direct an integrated test or manage the overall commissioning program. These are not interchangeable. Write down which kind of ownership your vacancy requires.

WBDG describes commissioning as a team process with assigned documentation responsibilities. A lead should be able to explain both their own decisions and the decisions reserved for the owner, design team or other authorized parties.

Use a candidate's real, anonymized example. Ask how the test was stopped or paused, what was preserved as evidence and how the team established a safe route to recovery.

Do not reward a dramatic story over a disciplined explanation. The useful details are authority, communication, traceable changes and the basis for the eventual result.

For a manager role, confirm team size, scheduling ownership, reporting obligations and the number of simultaneous test areas. For a technical lead, confirm hands-on depth. Requiring both can be appropriate, but the brief should say so and allow enough capacity for both jobs.
