AIB, to my mind, get a tough ride in the Technical community but I was fortunate enough to be audited by some of the "old guard" who are now close to retirement in the UK if not retired already.
They're not perfect at all but I learned a lot from them and I was reflecting just how much the other day.
- Not everything has to go on the list. If you have high confidence in the team and you feel like you're nitpicking, mention it and let the team get on with it. Or if it's one of a lot of issues, maybe roll them all in together.
- Get down and dirty on your hands and knees, torch in hand. Use a torch even if you can see clearly as it picks out things in a different way and helps you direct the auditee to what you're looking at.
- Do everything you can to spend maximum time in the factory. Standards matter but standards being applied matter more. Use the standards you find in reality to work back to the written standard rather than the other way round. That way gaps can be traced to where the issue is not working to assumed compliance.
- Poke around where someone has neglected to show you. The boiler rooms. The roof if safe to access.
- Focus on pest management. It should be a given but too often it's not. Look for potential risk then go back to the pest reports. Don't start and end with the latter. For example, a door which you have a gut feel is often opened, if there's an EFK nearby, take the number and see if there are a lot of moths and casual intruder flies. Or a drain that looks dirty, look for high drain fly / fruit fly counts.
