RPN stands for Risk Priority Number in reliability engineering. This metric is crucial in Failure Mode and Effects Analysis (FMEA), where it is used to assess and prioritize potential failure modes within a system. The RPN is calculated by multiplying three factors: the severity of the failure's consequences, the likelihood of the failure occurring, and the ease of detection of the failure. By focusing on these three elements, the RPN helps teams identify which failure modes pose the highest risks, thus guiding them in where to apply resources and efforts to mitigate or prevent those risks effectively. This prioritization is instrumental for reliability engineers in ensuring that the most critical issues are addressed first, enhancing overall system reliability and safety.
