Also called: potential failure modes and effects analysis; failure modes, effects and criticality analysis (FMECA) Show
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.
Failures are prioritized according to how serious their consequences are, how frequently they occur, and how easily they can be detected. The purpose of the FMEA is to take actions to eliminate or reduce failures, starting with the highest-priority ones. Failure modes and effects analysis also documents current knowledge and actions about the risks of failures, for use in continuous improvement. FMEA is used during design to prevent failures. Later it’s used for control, before and during ongoing operation of the process. Ideally, FMEA begins during the earliest conceptual stages of design and continues throughout the life of the product or service. Failure Modes and Effects Analysis Example
Note: This is a general procedure. Specific details may vary with standards of your organization or industry. Before undertaking an FMEA process, learn more about standards and specific methods in your organization and industry through other references and training.
A bank performed a process FMEA on their ATM system. Figure 1 shows part of it: the function "dispense cash" and a few of the failure modes for that function. The optional "Classification" column was not used. Only the headings are shown for the rightmost (action) columns. Notice that RPN and criticality prioritize causes differently. According to the RPN, "machine jams" and "heavy computer network traffic" are the first and second highest risks. One high value for severity or occurrence times a detection rating of 10 generates a high RPN. Criticality does not include the detection rating, so it rates highest the only cause with medium to high values for both severity and occurrence: "out of cash." The team should use their experience and judgment to determine appropriate priorities for action. You can also search articles, case studies, and publications for FMEA resources.

Confusion and various opinions about how to handle details exist. This article sheds some light on common confusion and disputes. Blueprint For Success (Six Sigma Forum Magazine) One area in which FMEA has not been substantively deployed as a tool of risk management is that of corporate real estate construction and management. This article applies FMEA to capital projects in architecture and construction.
