Posted By Harry Peter I took this course about 8 years ago when I was in the CAA. My then boss took it a few months later. We undertook one audit each and compared notes. We decided the audit was far too laborious and time consuming (both our time and that of management and staff of the units being audited) and we felt there was no additional benefits than if we had carried out a more 'traditional' style audit. I'd understood at the time that the HSE had a large input into the content and style and that inspectors were being trained in QSA techniques. I've dealt with a number of inspectors over the last few years and it certainly isn't obvious they were using them. My impression was, and still is, that the audit is a cumbersome tool and that the target needs to be very carefully selected if it isn't all just going to be a waste of time.
