OK, I just spoke to a VP of Operations, and he said, 2 customers do require it in their POs. However, he has been keeping track of the original lot number of the material that is die cut. It is stamped on the traveler and inputed into the computer. So we obviously are doing it.
But my argument with them is that if we get complaint, and I have to do corrective action with root cause analysis, I cannot trace that failed box to a particular person who worked on it
I can only trace it to the process, like the problem was die cutting, but we have 3 die cutters and there is no way as of now to tell, which one of them actually did cut it, THAT'S MY PROBLEM, purelly from ISO stand
