FMEA Example with Definitions
Notes on FMEA *A FMEA is a two-phase process. *First the potential failure modes and corrective actions are identified. *Then after the corrective actions are implemented, the product or process is re-evaluated to determine if the result is acceptable. *The Risk Priority Number (RPN) is the product of Severity, Occurrence and Detection. *These are assessed and engineering judgment is used to determine if the risk is acceptable. *Recommended Actions are developed to reduce the RPN with priority given to the highest RPN values and customer defined specific characteristics. *Once the actions are implemented, the Severity, Occurrence and Detection values are reassessed and a new RPN is calculated. *This process continues until the risk level is acceptable.
