What is an engineering change order (ECO) used for?

An engineering change order (ECO) is specifically utilized to propose changes after the initial design has been completed. This document initiates the formal process for requesting changes to the components or specifications of a project, which may arise due to design improvements, corrections, or new requirements. The ECO serves to ensure that all stakeholders are aware of and agree to the proposed adjustments, thereby maintaining clarity and accountability throughout the project development phase.

In contrast, the other options address different aspects of project management but do not accurately define the primary function of an ECO. For instance, while enhancing team collaboration is important in engineering projects, it is not the direct purpose of an ECO. Similarly, documenting project delays is a separate concern often handled through other forms of communication or documentation, rather than an ECO. Outlining project scope deals with defining the project's objectives and boundaries at the outset and does not involve change proposals once the design process is underway. Thus, the ECO's distinct role in proposing design modifications underscores its significance in managing engineering projects effectively.
