For each job, connect customer order, revision, material heat or lot, outside-process certificate, operator and inspection records, nonconformance, and final release.
A practical route
Pick a shipped order and trace backwards; then pick a material lot and trace forwards. Use identifiers people can read and systems can search. A traceability test should end in a bounded list, not a week of detective work.
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 traceability. to keep that chain together.
