failure mode and effect analysis (FMEA)

(1) A disciplined analysis of possible failure modes on the basis of seriousness, probability of occurrence, and likelihood of detection.

(2) A systematized group of activities intended to recognize, evaluate, and prioritize the potential failure of a product or process and its effects, and to identify actions that could eliminate or reduce the chance of the potential failure occurring, listed in the order of effect on the customer.

(3) A disciplined technique to identify and prevent potential failure modes. The FMEA provides a structured analysis in order to assess the probability of occurrence of a failure as well as the effect of the failure. A fully developed FMEA is continuously maintained and updated to reflect the latest actions and changes to the design or process.
