Severity
Quality
Severity
FMEA rating of the seriousness of the effect if a failure mode occurs.
Examples
- 01A loose brake-line fitting gets a severity of 10 in the FMEA because the effect is loss of braking without warning.
- 02In the supplier's FMEA review, the team checks that severity ratings were not lowered without a design change that removes the effect.
- 03Any failure mode with a severity of 9 or 10 must have a special characteristic and a dedicated control, regardless of occurrence.
