RPN (Risk Priority Number)
Risk Priority Number
Legacy FMEA risk score calculated as Severity × Occurrence × Detection.
Examples
- 01In the legacy FMEA, a failure with severity 8, occurrence 4 and detection 6 has an RPN of 192, just below the action threshold of 200.
- 02During the supplier review, the team explains why RPN thresholds are risky: a severity 10 item can score low and never receive an action.
- 03When migrating to AIAG-VDA, the team re-rates every item with an RPN above 100 using the Action Priority table instead.
