A Simple Engineering Change Record for Supplier Conversations

An engineering change can arrive as a marked PDF, a chat message or a revised sample. Treat each as a request until the team decides whether to adopt it. Otherwise price, tooling and production may quietly follow different versions of the product.

Record the decision path

Give the change a reference number. Log the previous and proposed revision, reason for change, affected parts, material or process, owner, approval date and effective order or batch. Record the commercial consequences separately: price, minimum quantity, sample cost, lead time and existing inventory. If testing is affected, name the test to repeat and who will accept the result.

Keep “requested,” “approved” and “released to production” as distinct statuses. A buyer can approve an appearance change while production still waits for a new tool or work instruction. Do not call it released until the current drawing, inspection plan and quote all agree.

Try a handoff drill: give the change record to someone who was absent from the meeting. They should know what to make, when to start using the new revision and what evidence is still missing. If not, the record needs another decision.

Worked example (illustrative)

A buyer moves a mounting slot after approving an earlier sample. The change record links the old and proposed drawings, asks tooling whether the existing fixture still works, and sends sales the result for price and timing review. Production receives the new drawing only after the release status changes from requested to approved.

Source check

Checked 2026-09-28. NASA configuration-management handbook treats an engineering change as a change to a controlled baseline with recorded status. The linked source supports this point only. The steps and worked example above are editorial guidance; they do not establish any supplier’s capability or guarantee a buyer response, order or delivery.
