In Failure Mode and Effects Analysis (FMEA), Risk Priority Number (RPN) is a measure of the potential risk associated with a particular failure mode. It is calculated by multiplying the likelihood of occurrence, the severity of the effect, and the detectability of the failure mode.<\/p>\n
The likelihood of occurrence is a measure of how likely it is that the failure mode will occur, with a higher number indicating a higher likelihood of occurrence. The severity of the effect is a measure of the impact of the failure mode on the system or product, with a higher number indicating a more severe impact. The detectability of the failure mode is a measure of how easily the failure mode can be detected, with a higher number indicating that the failure mode is more easily detected.<\/p>\n
The RPN is used to prioritize potential failure modes and determine which ones should be addressed first. Failure modes with a higher RPN are considered to be more risky and should be addressed as a priority. The RPN can also be used to track the effectiveness of corrective actions implemented to mitigate or eliminate the failure mode.<\/p>\n","protected":false},"excerpt":{"rendered":"
