What is FMEA?
Failure Mode and Effect Analysis (FMEA) and FMECA is an analysis technique which facilitates identification of potential problems in a design or process by examining the effects of lower-level failures. Recommended actions or compensation provisions are to reduce the likelihood of the problem from occurring, and mitigate the risk, if, in fact, occur.
The FMEA team determines by failure mode analysis, the effect of each failure and identifies single failure points that are critical. You may also be included in each fault according to the criticality of an effect of failure and its probability of occurrence. FMECA is the result of two steps: 1) Failure Mode and Effect Analysis (FMEA), and 2) Analysis (CA). Or in other words, it is only with FMEA FMECA Criticality Analysis.
There are many different types of FMEA. There are conceptual or functional FMEA, Design FMEA and Process FMEA. Sometimes, for a design FMEA analysis will a combination of functions and hardware. Sometimes they include only the hardware, and sometimes the analyst to take a detailed look at the system level to a piece of hand, especially when it comes to essential functions or hardware.
Why is FMEA or FMECA important?
There are a number of reasons that this analysis technique is so valuable. Here are just a few:
1) FMEA provides a basis for identifying the root causes of failure and the developing effective remedial actions.
Critical components 2) The FMEA identifies the reliability and safety.
3) Facilitates research on alternatives in all stages of design or process.
4) FMEA provides a basis for the maintenance, security, testability, and logistics analysis.
FMEA / FMECA Background and History
FMECA FMEA processes or a branch of Military Procedure MIL-P-1629, entitled to perform a failure mode and analysis, dated 9 November 1949. Originally used as a reliable technique to determine the effect of the system and equipment failures. Failures were classified according to their impact on mission success and personnel / equipment safety.
FMECA was developed and implemented by NASA in the early 1960 to improve and verify reliability of space program hardware. Call procedures in MIL-STD-1629A are probably the most widely accepted methods all military and commercial industry, but SAE J1739 FMEA is a very common standard used in the automotive industry.
This article only touches the surface FMEA, an analysis technique that has proven its worth time and again in many industries. There are many good books and other resources where you can find more information on FMEA. Both large and small companies will benefit as FMEA are an integral part of their quality programs.
