I think it's a separate thread but GFSI had a purpose (or the standards that make it up do) but that purpose is now lost. At least for sites who are well on the journey on compliance because that's ALL it encourages; compliance. Not actually doing it for the right reason. You can risk assess so much away on some GFSI standards which actually is a risk.
Anyway, soapbox also dismounted.
Back to the topic. I do some auditing, albeit limited. Generally I can type super fast. And I always use the evening on day one to write up to that point. Otherwise I'm not clear on what I've not covered for day 2, 3 etc. As a result, when I get to the write up, it's not a huge hassle. But some of these CBs have super restrictive systems which are stupidly time consuming to use. Anyone who is a slow typist or cannot spend their evening doing it (e.g. childcare or other responsibilities) are frankly screwed. I would never book back to back audits without having finished the write up personally. I'd be too confused but I am getting old.
Fact is though even with the evening work etc I'm probably doing a day's work but in my own time. Because for me there's no other way to do it. There's no way I see a fraction of the money you're being quoted though and I only get paid 0.5 days for write up too.
