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 analysis, [1] but may be put on a quantitative basis when mathematical failure rate models [2] are combined with a statistical failure mode ratio database. It was one of the first highly structured, systematic techniques for failure analysis. It was developed by reliability engineers in the late s to study problems that might arise from malfunctions of military systems.

These failures are debated in the public forum with manufacturers, service providers and suppliers being depicted as incapable of providing a safe product. Failure Mode and Effects Analysis, or FMEA, is a methodology aimed at allowing organizations to anticipate failure during the design stage by identifying all of the possible failures in a design or manufacturing process. Developed in the s, FMEA was one of the earliest structured reliability improvement methods. Today it is still a highly effective method of lowering the possibility of failure. Failure Mode and Effects Analysis FMEA is a structured approach to discovering potential failures that may exist within the design of a product or process. Failure modes are the ways in which a process can fail. Effects are the ways that these failures can lead to waste, defects or harmful outcomes for the customer.

This is a good time to break the Process Failure Mode and Effects Analysis into more manageable chunks. The list should be exhaustive — it can be paired down and items can be combined after this initial list is generated. There will likely be several potential failures for each component. Focus on the highest RPNs.

Failure Modes and Effects Analysis FMEA is a systematic, proactive method for evaluating a process to identify where and how it might fail and to assess the relative impact of different failures, in order to identify the parts of the process that are most in need of change.
