qualified internal iso auditor and basically ran the full audit timetable which involved a good fee audits every month. Loved auditing. basically take what they say and make a question out of it. also go through all SOP's standard operating procedures with guys om machines, office staff etc etc. Ask them to run through what they do and comare it. Writ eup the report with Non conformance or observations and then action to dept supervisor on timescales and go back and do all again.
you really need to be on yer toes and not deviate away form the standard or yer goosed. dont make it out to be too fancy or ye end up screwing yersle by trying to look good. Eventually i will write up some little manual for myself and follow it so if people ask on any commercial sites i can show them. little things like TDS checks, H&S issues, complaint procdures, yada yada yada
