Why this matters
Percentages here are derived live from the per-subsystem MC, Commissioning, and Turnover checklists, plus the Start-up Tracking and Reliability Run Tracking tables on the Commissioning page. To advance a step, tick the underlying gates in those modules.
Common field problems
Construction declared complete with open weld NDE; commissioning loops run on unstable ICSS; reliability run aborted early due to instrument drift.
Best practice
Hard-gate every transition. This workflow is the single source of truth across construction, commissioning, vendors, and operations.
