How does ECMS enforce traceability for changes?

• A. By linking ECRs/ECOs to affected materials, BOM items, routings, documents, test results, and approvals, and storing revision histories and statuses.
• B. By printing a change log on paper.
• C. By storing revision histories but not linking to materials.
• D. By not tracking anything.

Answer: (A)

Traceability in ECMS means being able to follow a change from its origin to every item it impacts, and to preserve a complete record of how that change evolved. The best approach is to link each Engineering Change Request or Engineering Change Order to every affected material, BOM item, routing, document, test result, and approval, and to store the revision histories along with their statuses. This creates an auditable trail that shows exactly what changed, why it changed, who approved it, when, and how the change affects related items and processes. It also enables robust impact analysis, so you can see all components and steps that are influenced by a given change and reproduce or review past decisions.

Printing a change log on paper or storing histories in isolation wouldn’t provide the same integrated traceability, and not tracking changes at all would leave no trace of approvals, versions, or affected items.
