Coming from a pharmaceutical environment where audits were frequent, constant and never announced, it comes down to living audit ready. Everyone and that means everyone has know that and live it as well. It has be to ingrained and as reliable as breathing. In the end it is easier than forgetting it for most of year and then putting a ton of work into getting ready.
Your system will also get stronger as when you are on top of the what is really going on, it forces you to make the changes to be more efficient and effective.
I couldn't agree more - there are no Plant Manager Rules, no Audit rules, no "My Name" rules. How can I expect employees to take me seriously when I need to teach them something important? "Make sure you check the metal detector when the auditor is around" "Make sure you wash your hands if you see an auditor"
To make sure we're audit ready I'm more into constant, street style mama shaming - I like to point out that uncovered ingredients are "nasty" or "gross" to the staff and ask if their Mom would be proud they did that or if they woudl let their Mom or kids eat that food.
I save "unappealing" and "entering a strange moral ground" for management, and dating temporary repairs and walking by them and making a face gets my machanic moving.
Also if I see something open/uncovered I walk up to it, wait for the operator, pretend a Marylin Monroe sneeze, then cover it.
When I see an open machine guard open I just stop them and close it, but I really want to take some of the industrial red food coloring and throw a mock emerengency Suspyria style.
