Its an engineering company with Sales, Procurement, HR, Field Support and Engineering (mainly) audited. Not rocket science. I have a form where I have taken all the Standards Clauses and put them in plain English (really). I have id'd the Clauses that apply to the Process and give examples in another column of a) the evidence to look for and b) other ways to rephrase the question for each process.
I wouldn't do audits like this, tbh. I think you're setting yourself up to fail. Apart from anything, you should be giveing "ownership" of the audits to the auditors. They need to plan the audits. It should be about the process not about clauses (in any language) and make them sit down with management when they come up with their things to check. When you do everything FOR the auditors they won't do the one thing you need them to, because you set a presecendent. Telling them what to look for etc is abrogating their responsibility for the work of auditing. I've seen it before and I was doing the remedial activities. TBH you may be beyond getting your current auditors back. I'd go with what @John C. Abnet suggest for a while, until everyone can see how to do them (as long as he doesn't just replicate the CB audits, that is )
