Hello all,
I would like to ask for an opinion of anyone, who has any experience with material comming to the production process. My understandind is, that PFMEA always consider all the incoming material (parst from which final product is assembled) as the "OK" one. when we are preparing PFMEA for any of the new processes, we do only failure modes, which can occure on currently considered work place. But some of my oponents in PFMEA team asking to consider possible NG material comming to the work place. but if I have incoming department which is responsible for material testing (visual check, 3D measurement, function test sampling, etc.), then why I have to add wrong material as failure mode and try to think out any C/M?
How can I explain, that in PFMEA there should be only "in station caused" failure modes, not failure modes which can occure before the work station? Well, but only if I am correct in my opinion of course. If I am not, please do not hessitate to tell me why.
Thank You all in advance for any posible comments/help.
