How do I document a process so someone else can follow it?
Quick answer
Write for a person who has not done the task before. State the process’s purpose, owner, prerequisites, and finish condition; then give numbered steps with one action per step and describe what the reader should see. Add what to do if a step fails, where to get help, and a date or version. Ask someone unfamiliar with the task to try the draft and note where they hesitate.
The question, the details, the next step.
A practical checklist
Name the reader, purpose, owner, start condition, and finish condition.
List prerequisites and where the reader should get approved materials or information.
Write numbered steps with one main action and an expected result for each important step.
Describe observable failure conditions and approved next steps; use placeholders where decisions need confirmation.
Have an unfamiliar reader try the draft, revise confusing parts, and add a review date or version.
A few more useful answers
How much detail should each step include?
Include enough for the intended reader to act and check the result without guessing. Explain unfamiliar terms or point to the team’s approved reference, but leave out background that doesn’t help someone complete or verify the step.
Should I document every exception?
Cover common or important exceptions the process owner can confirm, plus a clear stop-and-ask route for cases you haven’t documented. Don’t invent a workaround for an uncertain situation.
Who should review the finished guide?
Ask the process owner to confirm team-specific decisions, then ask someone unfamiliar with the task to test whether the instructions are understandable. They check different things: correctness and usability.
