Hi, I have two questions to submit:
First, I can't understand the meaning of "high degree of capability": Cpk/Ppk>=3 (see reference 4.9.2). Most of the time for us, a Ppk is higher than a Cpk because we carefully monitore all process parameters during a pre-launch. So, during full production, a Cpk has more chance to be lower than a Ppk. So, how can this equation be higher than 3 ?
Secondly, in the QS9000's third edition, are APQP, FMEA and PPAP have no significant changes. We plan doing nothing in those parts to update from second to third edition of QS9000. For me, these program elements have only been moved ?
