One thing that might not be obvious about checklists is how they're used.

I used to think checklists were used by reading the item, then doing the thing. I literally thought of them as a recipe that you would follow. Complete a step, check the box, repeat... This is typically referred to as a "read, do" checklist. In aviation this style of checklist is typically reserved for non-normal operations—procedures that you wouldn't use often enough to commit to memory.

The other style of checklist is "do, confirm". In this style you complete a procedure by memory, and read through a checklist to ensure you didn't miss anything (no box ticking, you just read the items and confirm to yourself that they're complete). In aviation this is the style used for normal operations, and for the initial action-items in an emergency (which although not commonly used, must be committed to memory because they are time-critical).

Because you're expecting that the procedure is completed by memory, a "do, confirm" checklist can be extremely brief. You do not need to write in detail what each step involves, you just need a word or two to name the step. Additionally, they're an extremely low operational burden; it takes a couple of seconds to read through a "do, confirm" checklist but the upside of catching common errors is significant.
