**Failure Mode Effects Analysis** Failure Mode Effects Analysis (FMEA) is a [[Six Sigma]] tool in the "Analyze" phase of [[DMAIC]]. The goal of an FMEA is to identify, categorize, and prioritize the failure modes of a process/project/or solution to a problem and decide when/which to mitigate. Similar to a [[Pre-mortem]]. # How to Perform an FMEA Abridged. 1. Brainstorm how a process/project/product may fail, using either historical occurrences or your imagination. Look at each of the individual parts that constitute the whole. Make a list of these failure modes. 2. Walk through the list of a failure modes & assign 3 scores to each: - "P" - Probability - how likely is the failure mode to occur? - "S" - Severity - if the failure mode occurred, how bad would it be? - "D" - Detectability - how easy is it to tell if the failure mode is occurring? 3. Consider the overall risk of each failure mode by taking "P"x"S", and consider "D". **** ## Source - [[Wikipedia]] - [Failure mode and effects analysis - Wikipedia](https://en.wikipedia.org/wiki/Failure_mode_and_effects_analysis) ## Related - [[Six Sigma]] - [[Pre-mortem]] - [[Plan for Failure]] - [[Don’t use “Absence of a Signal” as a Signal]]
