DO IT FIRST, THEN CONFIRM
With a CONFIRM checklist you perform your job from your memory or your experience. Then you check the items off the checklist and confirm everything was done accordingly.
This type of checklist is often found in the aviation industry in procedures like taking off or handling a disaster. When you’re handling something unexpected, your emotion is in the way so the chances of missing something can be huge. Using this type of reminder checklist is a great way to make sure everything is done right and in the right order.
