I kinda want to go home and back to my lack of having a life there but I have a dFMEA to finish for work.
For those that don't know dFMEA stands for "design failure mode and effects analysis" which loosely translates to "engineering for people who are shitty engineers and can't identify failure points." Basically you arbitrarily assign values from 1-10 to failure modes for severity, probability of occurrence, and likelihood of detection to determine the risk of a certain failure.
It's pretty much a huge waste of time, tedious as fuck, and is driving me fucking crazy. Fuck my life.

That does sound like a pain in the ass. I work as a mechanical engineer at a small electronics manufacturer and our failure mode analysis work tends to take the form of walking out into the parking lot and throwing a prototype device around until it breaks or reads out of tolerance. Ah, the joys of having a 4 person R&D/Engineering dept.

Making an FMEA is pretty standard at a lot of places. And at most places it's just an FMEA, no idea who teaches it as a "dFMEA".

The d is for design. You can have service and manufacturing FMEAs as well. It's basically the same thing but for a different part of the product development process. Most of the FMEAs I've done have been system level but our customer wants it all the way down to the part level. It would be nice if it could just be generalized by types of parts rather than having to go part by part.
I see the value from a documentation standpoint but it's literally just going through the motions.

I wouldn't consider the severity values arbitrary. They fit pretty specific categories as of t he last round of AIAG manuals.
They are a bull shit document though. Totally agree with you. After the PFMEA is generated and once the Control Plan is in place and production has validated it's effectiveness its just there to add new Cock ups to.
My fave is when they ask what the PFMEA says. Well jackass, if it was in there it would be addressed and not have happened, now would it? My guess is it's something else....
