CAPA-301 exposure-adjusted effectiveness review
The raw count halves, but recorded operating exposure falls to one quarter of the earlier period. Dividing events by hours yields 0.5 before and 1.0 after per 1,000 hours. This is not evidence of improvement from fewer events alone, nor proof that the action worsened performance. Check population comparability, observation windows and uncertainty before reaching an effectiveness conclusion.
Source evidence and search scope
PRE-301 (Before action); POST-301 (After action); CAPA-301 (Action record)
PRE-301 / Before action
- Recorded evidence
- 4 events in 8,000 operating hours
POST-301 / After action
- Recorded evidence
- 2 events in 2,000 operating hours
CAPA-301 / Action record
- Recorded evidence
- Implementation complete; effectiveness review open
Inputs needed for your own records
- CAPA action, implementation evidence and effectiveness plan
- Comparable events and operating exposure before and after the change
- Exclusions, related changes and open investigations
The CAPA owner and quality reviewer decide effectiveness. Action completion or a lower raw count is not automatically evidence of improvement.
