Risk Priority Number (RPN)
When performing a Process or Design FMEA, the Risk Priority Number (RPN) is a calculation to sort the risks from highest to lowest.
The RPN is calculated by multiplying the three scoring columns: Severity, Occurrence and Detection.
RPN = Severity x Occurrence x Detection
For example, if the severity score is 6, the occurrence score is 4, and detection is 4, then the RPN would be 96.
