What is an engineering change order (ECO)?

An engineering change order (ECO) is a formal request to modify a design. This process is crucial in engineering and manufacturing as it enables teams to document proposed changes to product designs or specifications. An ECO typically outlines the reason for the change, the implications it might have on production processes, costs, and timelines, as well as any new requirements that would arise from implementing the change.

This structured approach helps ensure that alterations are properly assessed, approved, and communicated across relevant departments, reducing the risk of errors and ensuring compliance with the overall project goals. In industries where precision and adherence to specifications are paramount, an ECO functions as a vital tool for maintaining product integrity and quality throughout the development cycle.
