I am looking for an historical description of the requirements of automotive principals concerning the PPM since the giving up of the AQL. Web sites, books, reviews, ... ASAP. Thank you very much.
I think that was the deal.Sam said:
Marc, Didn't Crosby advocate doing away with the AQL with his "Zero Defects" process in the late 60's?

In the Dr. Wheeler´s book Understanding SPC, paragraph 6.3 there are some explanation related with Cp values and PPM nonconforming. In page 130 he concluded:..."The conversion of capability values into fractions nonconforing is an operation thta has no contact with reality. It is nothing more than fantasy, and the results are illusion, if not outright delusions."
IMO this a related matter with the topic in discussion.
