Techopedia explains Failure Mode and Effects Analysis (FMEA)
In general, IT professionals can use failure mode and effects analysis (FMEA) as part of a greater reliability study for an IT architecture. Here, the various parts of the system are put together and reviewed to show how they work together. Different kinds of FMEA, including functional, design and process FMEA, are generally organized into simple worksheets or other documents.
Failure mode and effects analysis is generally an engineering tool. Through deductive analysis, it helps experts looking at IT systems to figure out the different kinds of risk and liability, as well as how failure would most likely occur. These kinds of high-level planning help to safeguard investments in IT and provide project backers with more assurance of quality testing and high-level engineering review.
