Re: ISO 9001 - Process audits
I've noticed that CB auditors' interpretation of some elements in the standards vary, but the fact is that in ISO 9001:2008 the Quality management systems - Requirements start with 1, Scope. To be enforceable, a process approach to auditing would need to be included in the Requirements section.
I have looked for more guidance on this in the ISO informational documents titled Guidance and Use of the Process Approach for management systems and found "audit" referred to only as one example in a list of measurement processes. Even ISO 19011:2015, Guidelines for auditing management systems, refers to the process approach only as one of the listed recommended skills auditors should have (see A.4, page 32). I even did a search for "process audit" in ISO 17021:2011, Conformity assessment - Requirements for bodies providing audit and certification of management systems, and found nothing.
Based on all that, I would write an Opportunity for Improvement suggesting the process approach to auditing in order to help measure process effectiveness, but I wouldn't write a nonconformity because there isn't anything in the Requirements part of the ISO 9001:2008 standard to write it against. If ANAB reviewed my audit report and decided I had "softgraded" with this OFI, I would welcome that as input based on the lack of anything more substantial.

One of my clients used a well-known / reputable registrar and apparently the company line from them was that, because of 0.2, the process approach to internal auditing was a hard requirement and we (my client) would receive an NC if the process approach was not followed.
We had the choice of taking the process approach (which, as Randy points out certainly has merit) or changing registrars. This point was non-negotiable with them. Other registrars (different clients) weren't so rigid.
This is not intended to disparage the registrar or dispute their approach but just point out that there may be some registrar-dependent variances.
