Document control makes the right instruction easy to use and the wrong one hard to use.
A practical route
Define who drafts, who approves, how revisions are identified, where the current copy lives, and what happens to printed copies. Test one real change at the machine. Download the document change request form.
What good looks like
The process is visible at the point of work. The person doing the task knows the current requirement, the person approving it can see objective evidence, and the owner can tell whether the control worked. Keep the record small enough to complete in the moment: requirement, result, exception, owner, date, and next decision.
The failure mode to avoid
Do not solve a recurring process problem with a longer form alone. Watch one real job, find the handoff that breaks, and change the workflow or responsibility. Then sample the next few records to confirm the change stuck. The output should be a record someone else can verify. Use the document control. to keep that chain together.
