Greetings,
I am a QE that has transitioned from a IATF Tier 1 to a Tier 2 and we make a single components to send to a tier 1 assembly facility. Our process produces an incomplete part every 10000 cycles, and have issues with them escaping to customer. Our process shows satisfactory capability and excellent PPM, however customer still demands 100% sort all parts made when they receive defect. Sorting 50000 parts (typical batch size) for an unfinished part seems unnecessary granted extremely low possibility that defect can occur.
Is it reasonable to push back on these demands for 100% sorts and put more pressure on the customer to provide statistically relevant data to justify such a sort?
Any feedback is appreciated.
Greg
