Capture revision, material, special process, inspection, packaging, record retention, and flowdown requirements before acceptance.
A practical route
Sales confirms what was promised, engineering confirms what can be made, quality confirms evidence, and purchasing confirms outside-process capacity. Link accepted requirements to the traveler so a promise becomes a controlled input.
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 contract review. to keep that chain together.
