工程变更单（ECO）

一个 Engineering Change Order (ECO) is a formal document that outlines modifications to a product’s design or manufacturing process, ensuring that all stakeholders are informed and aligned on the changes. It typically includes details such as the rationale for the change, the affected components, and the implementation timeline, facilitating effective 沟通 and minimizing disruption. The ECO process is critical in maintaining product quality and compliance while fostering continuous improvement in engineering practices.
