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.

The goal of FMEA is to ensure organizations consistently release high-quality products to market. Initially developed by the U.S. Armed Forces during the 1940s, FMEA allowed troop leaders to identify failures impacting mission safety. As mentioned above, PFMEA is a subtype of FMEA with a focus on process improvement.

An FMECA (Failure Modes, Effects, and Criticality Analysis) is an extended FMEA that includes a risk assessment to prioritise the failure modes with the biggest impact. These failure modes are then reviewed for possible mitigations to reduce the risk. One method of prioritisation that is often used in FMECA is the Risk Priority Number (RPN).

Criteria for FMEA Analysis. An FMEA uses three criteria to assess a problem: 1) the severity of the effect on the customer, 2) how frequently the problem is likely to occur and 3) how easily the problem can be detected. Participants must set and agree on a ranking between 1 and 10 (1 = low, 10 = high) for the severity, occurrence and detection ...
In its simplest definition, a Failure Mode and Effects Analysis (FMEA) is a risk management tool that aims at identifying and quantifying the influence of potential failure (s) in a production process. Failure modes refer to the processes in which something can fail. On the other hand, effects are ways in which failures can result in ...
The Failure Mode Effect Analysis (FMEA) tool is a useful way to account for errors and their effects. It was first developed in the 1950s to keep a check on any malfunctions in the US military.

Machinery FMEA is a methodical approach used for identifying risks associated with machinery and equipment failure. The purpose of the MFMEA is to increase reliability of the machinery, reduce time to repair and add prevention techniques, such as diagnostics. MFMEA is an integral part of Total Predictive Maintenance (TPM).
Begun in the 1940s by the U.S. military, failure modes and effects analysis (FMEA) is a step-by-step approach for identifying all possible failures in a design, a manufacturing or assembly process, or a product or service. It is a common process analysis tool. "Failure modes" means the ways, or modes, in which something might fail.
Because there are various types of FMEAs, sometimes a qualifier prefix may be used. For example, Design FMEAs can be referred to as "D" FMEAs, and Process FMEAs as "P" FMEAs. In general, the term FMEA can apply to the broad scope of any type of FMEA analysis, but if you want to be specific, you can use the prefixes.
