There's plenty of checklists in the medical field as well. Specially during triage of all kinds.

The main issue is that in most jobs people will say new checklists won't work for /them/ because they understand it better than the checklist, or because the checklist will slow them down. Think about your own work and you'll find reasons why checklists don't make sense, I bet.

I once went in for a surgery on a foot and when rolled into the room the doctor asked me if I had any last minute questions and I asked only 'which foot are you operating on'. After a few seconds of confusion he gave a decisive right answer and even told me 'here, if it makes you feel better I'll sharpie your leg'. And it did make me feel better - there's so much that can easily go wrong by a minor mistake from them which will be life changing for you.
