Write a checklist that has a clear finish line
An empty box helps only when the reader knows what earns a checkmark. “Preparation” is vague; “put the charger in the bag” has a visible end.
One action, one outcome
Use a concrete verb and object. Split “call the venue, pay and save the receipt” into separate tasks so a tick cannot conceal unfinished parts. Define completion before starting.
Order it for the moment of use
A travel list might group tasks before departure and at the door. Digital.gov recommends lists for scanability; our execution-order suggestion is practical advice, not a guarantee against errors.

Prepare the paper version
Leave boxes empty for pen marks or retain completed checks when handing over progress. Review long lines in print preview. A checklist is not a substitute for specialist safety instructions.
Example: a small meeting
Replace “meeting” with: confirm the time, send the location, prepare 15 copies, test the presentation and record decisions. Each line can be checked independently.
If only 10 copies are ready, do not tick “prepare 15 copies.” Add “5 remaining” in notes. A tick should mean the stated condition is complete, not merely started.
