I make checklists for myself and they're enormously helpful. Because my brain can't always remember every single little detail of every complex task every single time.

I've also seen checklists made by morons that are enormously unhelpful.

IMO it's paramount for whoever is making the checklist to have familiarity with the task at hand (both how to do it properly, and what steps people tend to miss or get wrong), investment (is this tool something you'd find indispensable for yourself if you were placed in the role of executing it?), a sense of pragmatism and conciseness.

The ability to recognize what things will be obvious or flow naturally from A to B helps eliminate redundant fluff. e.g. I train volunteer firefighters and in most canonical steps for calling a Mayday, one is basically "Tell the person on the other end what's wrong". You don't need a checklist item for that. When something goes seriously sideways and you need help, you will be very inclined to convey what is the matter.
