Failure modes and effects analysis – Wikipedia
In this study, both software FMEA and system FMEA were applied in the following five steps: 1. System FMEA is the highest-level analysis of an entire system, made up of various subsystems. The focus is on system-related deficiencies, including system safety, system integration, interfaces or interactions between subsystems or with other systems, interactions with the surrounding environment, human interaction, service and other issues that could cause the overall system not to work as intended. Se hela listan på de.wikipedia.org Failure mode and effect analysis (FMEA) is a structured approach to identifying potential failure points in different systems like products (Design FMEA) and processes (Process FMEA). It consists of finding weak points in components, assemblies, and subsystems and reviewing how their failure would impact the rest of the system they are a part of. FMEA (Failure Mode and Effects Analysis, also known as Failure Modes and Effects Analysis or Failure Mode Effects Analysis), is a procedure used to pinpoint where certain systems or machinery might fail.
It is intended to investigate an entire system and check whether all of the individual components within it work together correctly. Actions can be derived from the analysis. System FMEA is the highest level analysis of an entire system , made up of various subsystems. The focus is on system - related deficiencies, including system safety, system integration, interfaces or interactions between subsystems or with other systems, interactions with the surrounding environment, human interaction, service, and other issues that could cause the overall system not to work System-FMEA. Die System-FMEA (auch: Systemanalyse) ist ein Teilbereich der FMEA (Fehler-Möglichkeits- und Einfluss-Analyse). Sie soll das System insgesamt untersuchen und prüfen, ob alle einzelnen Komponenten darin funktionsgerecht zusammenwirken.
It was first developed by the US Department of Defense for use in systems System FMEAs are designed to understand the overall reliability of the system and the adverse effects of failures at a system/subcomponent level on the customer.

Feleffektsanalys - Failure Modes and Effects Analysis FMEA
For example, a design FMEA would list the testing methods that are used to make sure that a part is durable for the life of the vehicle as a current control. The controls are then given a detection rating for how good they are at finding the fault with the system. System FMEA is the highest-level analysis of an entire system, made up of various subsystems.
