I want to set up a plan in our receiving inspection department to audit supplier inspection results on complex machined parts. These parts have numerous critical dimensions (about 40 per part), which I would have a supplier verify per Z1.4. I am planning to have the supplier submit these results with the parts.
The difficulty is in confirming the supplier data in a statistically valid and cost effective manner. Have you ever seen a plan where only a sample of characteristics are verified on a sample of parts? The sample of characteristics could be random or rotating (cyclical).
What are your thoughts?
