Proposal to merge Failure mode, effects, and criticality analysis into Failure mode and effects analysis
I propose to merge FMECA into FMEA, continuing previous discussions in 2007 and 2010 on the FMECA talk page (see Talk:Failure mode, effects, and criticality analysis/Archives/2012). The reasoning is that there seems to be a large degree of overlap and small variation between the subjects, and per the comments in that thread the criticality analysis seems to be a small extension that may or may not be done based on an assessment of the FMEA analysis. The topics of FMEA and FMECA therefore seem quite similar so that it seems logical to have the information in one article. Sauer202 (talk) 09:51, 30 December 2023 (UTC)


 * MIL-STD-1629 Failure Modes Effects and Criticality Analysis for decades has been associated with a range of defence aerospace reliability and safety studies.
 * It's such a useful and widely used approach because it emphasises the need to base analysis on functional block diagrams (or other system description),understand how systems work, and how individual failures impact the next higher level and the overall system.
 * Once that basic approach is understood, then tailoring for various applications and safety studies, automotive production lines, input data to other safety and reliability work including fault tree analysis can follow.
 * Then you can branch off to various analysis approaches looking at things like detectability, simple fmea, and all the rest.
 * You need to get the basics right, and that includes Criticality. I'd hate to lose the history and heritage associated with the acronym FMECA by putting it under the heading of FMEA Wombat833 (talk) 06:33, 16 January 2024 (UTC)
 * just worked out what's bugging me. It's a factual error to say that FMECA  is an extension of FMEA.
 * It's the other way round. For decades, the analysis approach was known as fmeca. That needs to be  the title of the article, and FMEA  considered a derived process or approach.
