Now 19011 is specifically required to exclude 3rd party audits (wrong IMHO but there you are) and I have long despaired of getting anything useful out of 17021 but both standards do talk about avoiding bias and, in my answer to Bonhomme (what a good man he is!

). I tried to explain where the bias can come from. So my recommendation (for the avoidance of bias) is the auditor takes his / her own sample and leaves internal audits to last. It also means they have to do the job they've been paid to do rather then regurgitating the orgs own internal audit results back to itself.
I also think the 'dumpster items' you mention are all largely end of audit topics, relating as they do to the Check / Act part of the cycle.
... and you and I agree on next to nothing but that's OK.
... nobody said that. To save you looking back at the thread I answered Bonhomme's question of why looking at internal audits early on could bias an auditor's sample. Period.
Really? What does your CB contract with the auditee say? From memory there is no requirement in 9001 that you open up customer audits (for example) for 3rd party scrutiny. If the auditee chooses to put the results through their corrective action procedure (as many do) then they're fair game. Again not in Bonhomme's original question.
Agreed.
You have stretched the requirements beyond the standard but again if customer audits are summarized for management review then fine ... to be looked at at the end of the 3rd party audit.
