Which statement about ECO is true?

Which statement about ECO is true?

• A. ECO is an approval and implementation of a change to design or process.
• B. ECO is a proposal to change a design.
• C. ECO is a final report after production.
• D. ECO is a risk assessment tool.

Answer: (A)

An Engineering Change Order is the formal authorization and execution of a modification to a design or a manufacturing process. It captures why the change is needed, what exactly will be changed, and which items are affected, then lays out the plan to implement and verify the change. After approval, the ECO drives updates to drawings, parts lists, tooling, work instructions, and revision control, ensuring everyone uses the correct version and that the change is traceable from request through completion. This is more than a proposal or a plan; it’s the formal, approved action that delivers the change into production or design practice. It’s not a final report after production, and it’s not a risk assessment tool, which serve different purposes.
