What scoring indicates a high likelihood of detection in FMECA RPN?

In the context of Failure Modes, Effects, and Criticality Analysis (FMECA), the Risk Priority Number (RPN) is a crucial metric used to assess the risk associated with potential failure modes. The RPN is typically calculated by multiplying three factors: Severity, Occurrence, and Detection.

Detection scoring specifically evaluates how likely it is to detect a failure mode before it results in failure effects. A higher score in the Detection category indicates that the likelihood of identifying and managing the failure mode is lower, meaning that the detection measures in place are not as effective.

A score of 1 represents a high likelihood of detection, suggesting that the system or process is very capable of catching the failure before it leads to adverse consequences. This makes it the ideal score for ensuring effective risk management. Therefore, for indicating a high likelihood of detection, a score of 1 is considered best practice in FMECA analysis.
