What is PM compliance?

The share of scheduled preventive work actually done on time.

PM compliance measures completed-on-time preventive work as a percentage of what was scheduled. 90%+ is the usual target; below that, deferrals compound into backlog and failures the PM was meant to prevent.

Teams report PM compliance weekly by crew and site. When it slips, the cause is usually capacity, parts or access — the metric tells you maintenance is failing before the assets do.
