Failure mode and effects analysis (FMEA; often written with "failure modes" in plural) is the process of reviewing as many components, assemblies, and subsystems as possible to identify potential failure modes in a system and their causes and effects. For each component, the failure modes and their resulting effects on the rest of the system are recorded in a specific FMEA worksheet. There are numerous variations of such worksheets. An FMEA can be a qualitative a…

WebApr 4, 2024 · Applications of FMEA and FMECA may (or may not) begin with identifying functions. If functions are included, the functional definition is typically defined at the component level rather than at the functional system level. This can lead to missing or overlooking a substantial number of failure modes. Understanding the RCM Methodology
