In change management, what does an Engineering Change Order (ECO) represent?

• A. Approval and implementation of a change to design or process.
• B. A proposal describing a change but not approved.
• C. A failure to document a change.
• D. A change rejected by the CAB.

Answer: (A)

An Engineering Change Order represents the formal authorization to implement a modification to the product design or the manufacturing/process. It codifies what will change, why, which items are affected, the revision level, and the plan for implementing the change, and it moves the change from proposal through approval by the Change Control Board to actual execution. This is why it best fits: it is the official step that authorizes both the change and its execution, not merely a proposal, not a documentation gap, and not a rejection.
