Next-Generation Failure Analysis from NANEVA
By Bruce Jenkins, President, Ora Research LLC
Failure mode and effects analysis, or FMEA, is a systematic technique for failure analysis originally developed by reliability engineers in the 1950s to study problems that might arise from malfunctions of military systems. Broadly defined, FMEA today is “a systematic group of activities intended to:
- recognize and evaluate the potential failure,
- identify actions that could eliminate or reduce the chance of the potential failure occurring, and
- document the entire process” (AIAG, “Potential Failure Mode and Effects Analysis (FMEA),” 3rd ed., 2001).
Primarily a qualitative rather than quantitative analysis, FMEA is an inductive process based on experience with similar products and processes, or on common physics of failure logic.
