It must become a culture. In Japan, there's a culture in the public transport business (trains etc) of 'point and say' where each responsible crew member points at a target e.g. safe door open zone marked on the pavement, and says out loud that its correct or not. Its a physical reenactment of a checklist? Anyway it becomes second nature if its a physical act, not a check-the-box-on-a-form thing. So that's how they manage it not getting skipped/becoming just paperwork.
