Hey, everyone!
I apologize ahead of time, I checked forum for similar topics, but my time is limited, so I didn't check everything.
I have automotive customer, who came on site (short notice) and his demand is that we show that we are capable on characteristics that are not defined as special characteristics on drawing or other specifications. Their standard states that only special characteristics must have Cpk of 1.67 and Ppk of 1.33. This was PPAPed and signed some time ago.
This customer brought with him some black belt, that I can't really speak with as I'm not as proficient in six sigma. This person says that even if we have good trend there is possibility that we are out of tolerance limits for some parts due to spread.
My questions are:
1. Is there demand that all measurements must have capability of 1.67 or 1.33?
2. How to continue this discussion with customer and black belt? We have meeting in 3 hours.
I really hope for some feedback and thanks everyone ahead of time!
I haven't posted for really long time, but this forum was my escape pod few years ago when I was burned out due to transition of ISO/TS to IATF.
This customer is giving me similar feeling, so this forum is first thing I tough off.
Take care!
Best regards,
Ray
