Detection

FMEA rating representing the ability of current controls to detect a failure cause or mode before escape.

Examples

01In the PFMEA, a missing O-ring gets a Detection rating of 8 because it is only found by visual inspection.
02During the supplier's FMEA review, the team challenges a Detection rating of 2 for a check that relies on a manual gauge without error-proofing.
03After an escape, the team lowers confidence in the existing check and re-rates Detection, which raises the action priority.
