Agreed Howard,
Even within the big 3 there are variations on what they want, and we give them what they want. But when it comes to rubbing your back against the tree there are certain numbers of samples and group sizes that are required and as long as the warrant is signed and there is evidence that you will improve on the process, there will be no problem.
To anybody, just think that because a B3 engineer sais he wants this or that, that an auditor will not disagree and issue a finding. Sometimes, even when you have it in writing it does not mean the auditor can't site a nonconformance.
