If they inspect a piece of equipment and it is not serviced correctly (and CQC inspections are hands on like you say, in some respects), they need to look at what we do to ensure that these are not recurring incidences. So you need to have the paper trails in place that give you assurance its all being done correctly and items arent being missed etc, and that service personnel are competent..
I would imagine that if you had random sampling that this would go a long way to checking technical personnel are doing it correctly. However I also read on here people keeping stats as to breakdowns and other stats for engineers, against national averages, and where its higher, it can be used to identify training requirements. Not sure how often such a system is used. Training certs seem to be inappropriate because engineers I guess build up general competencies that can cover a range of items which wouldn't be covered by certificates all the time?
