Failure-mode-effects-analysis (FMEA) is a structured, proactive reliability-engineering method that: (1) decomposes a system, component, or process into its constituent functions; (2) identifies every possible failure mode for each function — how it could fail to perform its intended purpose; (3) determines the effects of each failure mode on system operation and safety; (4) assigns severity, occurrence, and detectability ratings to each failure mode; (5) computes a risk priority number (RPN) from these ratings; and (6) prescribes corrective actions for the highest-priority modes. The mechanism of persistence is institutional documentation — standardized worksheets, databases, and review processes embedded in engineering practice.

Definition
Why it is in scope
A systematic reliability-engineering method for identifying potential failure modes in a system or process, analyzing their causes and effects, and prioritizing them by severity, occurrence, and detectability to guide corrective action.
