In many FMEA trainings and on wiki the origin is described as MIL-P-1629 Procedures for Performing a Failure Mode, Effects and Criticality Analysis from 9.Nov. 1949, but who have seen this document?

I don't want to get into a fight with Wikipedia over what reminds me of a variant of the Berenstain Bears/Mandela Effect... but when I was initially learning and reading about FMEA (not FMECA) I have a recollection that what we would now recognize as Process FMEA was implemented in the early 20th century at a variety of automotive factories (naturally Ford plants got the credit). I'm far too lazy and have no interest in "proving" this assertion either way, but the RPN approach to focusing attention always made more sense to me as something that would happen on a factory floor rather than in a design house.

Yes, I recall some debate 1-2 years ago on Elsmar? as to what input or value the blue oval may have contributed...yet many processes procedures we use and benefit from have their origins in DOD and the like from 40s, 50s, 60s? Re: my prior post was a result of querying AI apps..

Ford's (post-1970s) efforts in FMEA space were certainly widely shared for obvious reasons: lots of partners, lots of (former) employees... my (imagined?) recollection was that the early auto manufacturers realized that mass-production/assemblies lines were just as efficient at making reproducable manufacturing defects as products, and were able to quantify the cost of defects that led them to (what we now recognize) as PFMEA. It's entirely possible that my recollection is muddied by HF Museum/Greenfield Village displays which are under no obligation to be 100% historically accurate,
 
Yes well the 1949 version was MIL-P-1629.
A quick search I performed turned up nothing. You might try the “wayback machine” - a simple google will get you there.
