I worked at a company that used mandatory checklists for some operational roles, they definitely cut down on the number of mistakes (at least the mistakes the checklist was crafted to address). It made people more accountable: whereas previously a certain mistake might be human error (unavoidable), if it still happened after the checklist then either somebody didn't fill out the checklist (and could be punished for negligence) or lied by checking a box on checklist without actually doing the thing (and could be severely punished for dishonesty). This motivated people to thoroughly check the things.
