What it shows
The part of classified prevention cost that is planned ahead (training plans, FMEA, supplier qualification, preventive maintenance, calibration and audit plans) rather than triggered by a failure (corrective actions, retraining after an incident). Uncategorized sets are left out; the line below says how much of prevention cost is classified.
Why it matters in manufacturing
Planned prevention stops problems before they happen. Prevention that only starts after a failure has already paid the failure cost once. A plant that spends mostly on reactive prevention is fighting fires rather than preventing them.
How to read it
Higher is better. The tag compares with the same period last year in percentage points. A sudden drop usually follows a large failure that set off corrective work.
What good looks like
A high share that holds or rises: most prevention is scheduled ahead, and reactive work after failures stays a small part.
