What is FMEA?

■.  What is FMEA (Failure modes, effects, and criticality analysis) ?

 FMEA is one of the first systematic techniques for failure analysis. FMEA was developed by the U.S. Department of Defense and the first guideline is [MIL-P-1629] “Procedures for performing a failure mode, effects and criticality analysis” established on November 9, 1949 in the U.S. Military Standard. FMEA is most often used as a reliability analysis technique in the early stages of system development. FMEA is usually performed at the concept or early design stage to identify all possible failure types and take appropriate actions to reduce failures.

■.  FMEA form

 

 Usually, you can refer to the form below and modify it slightly for each company. The most important thing in FMEA is to actually do it. Manufacturing, quality, development, and design personnel should all gather to conduct FMEA on expected defects and take corrective actions according to risk priority (RPN).

 

 I think the most important thing in FMEA is practice. There are many people who think that there is no big change in quality even if they are busy. If you organize a circle meeting and keep it for one year, there will be a big change in quality improvement, so please try it!!!
