General FMEA Question

[lululala]

Really needed some guidance on classifying certain failure modes at my company. We are in the early stages of design and development and have drafted an extensive DFMEA (we're in good shape from the design side). While brainstorming with the engineers a question that I didn't think much of came up; when we receive parts from a supplier where we visually inspect the part before the part goes into an assembly, if the part does not pass the visual inspection from the design drawing (SolidWorks) is this considered a process failure from the supplier? What about at our company? Would this double down as a design failure since it does not meet the drawing spec of the design we have on file that is a released part in our system? The engineers on my team are thinking beyond the scope, but typically I am used to capturing this as a process failure and it would be captured in the Supplier's PFMEA.

Thoughts?

Also if you receive a PCB and you have to pre-test it prior to utilizing it in manufacturing and the pre-test fails wouldn't that be a design failure and not a process failure since the PCB came malfunctioning?

I would put incoming goods not meeting specification as part of your PFMEA.

DFMEA is ensuring the specification is correct, PFMEA is ensuring the production process can meet the specification.
