Which statement about an ECN within a formal change control process is correct?

• A. It budgets the cost of the change.
• B. It approves the change after senior management sign-off.
• C. It communicates the change to the supply chain only.
• D. It documents and communicates the change and authorizes implementation.

Answer: (D)

Within a formal change control process, an ECN is the formal document that records the proposed change, communicates it to all affected parties, and provides authorization to implement it. It serves as the single authoritative record of what will change, why, which items are affected, the planned implementation steps, and who is responsible for each action, along with verification requirements. This structure ensures traceability, accountability, and controlled execution, preventing unauthorized modifications and ensuring alignment with quality and regulatory expectations. The ECN isn’t about budgeting the change—that task belongs to cost estimates or business planning. It isn’t simply the act of senior management signing off, which is governance; the ECN is the directive that enables implementation once approved. And communication through the ECN reaches the relevant stakeholders across the supply chain and internal teams, not just one group.
