Turning a checklist into a workflow another person can run

A checklist says what to remember; a reusable workflow also says when to start, what inputs are valid, who owns each step, and what counts as finished.

Group steps into preparation, execution, review, and handoff. Add a path for missing inputs and partial failure, plus a rule for retries so repeated runs do not duplicate work. Have someone else run a small case using only the written instructions.

Which checklist step still depends on unwritten knowledge?
