According to my Auditor, LRQA, yes, the famous process map does have to be included in the QA Manual. I found that difficult as I share my Manual with another division, and our processes are different. I tried referencing the process map in the manual as a tier 2 document and ended up with an improvement note from my auditor. I ended up making a generic Input-Process-Output diagram that both divisions could use, based on an article in the March 2002 Quality Progress.
I get more use from my detailed process map, but circumstances forced me into the generic version.
I did re-format our quality manual so that the sections in the manual correspond to the sections of the standard. I think it makes it easier to use during audits, and it helps my audit team relate our QMS to the standard.
