Test whether critical steps are clear and verifiable in the field, not the item count.
Build the checklist by observing the actual workflow. Each item should have one observable check, a result field and a step for deviations. Trial it during a real tour with staff; revise unclear, duplicated or unused items. Keep critical controls in scope and name the owner and review trigger.
There is no fixed item count that makes a checklist right. It should be quick to understand without skipping critical work.
Observe the task and phrase items as actions: what to check, where to record the result and whom to notify if it fails.
Have staff use it during a shift, then review skipped, ambiguous or repeated fields with them. Version revisions and trial again.
