Definitions
Commissioning is the on-site process of aiming, testing, measuring, and recording evidence so the system can be accepted and operated reliably.
Typical target ranges
Target: a complete sign-off pack at handover.
All key decisions recorded: aiming, scenes, deviations.
All stakeholders know what they sign and when.
Step-by-step workflow
Engineering diagram (workflow).
Workflow: define tier → map constraints → test 4/6/8 pole options in calculation → choose option with best risk profile → lock aiming limits and sign-off deliverables.
