What is an Engineering Change Proposal (ECP)?

An Engineering Change Proposal (ECP) is fundamentally a formal document that outlines proposed changes to a system, product, or process. This formalization is crucial because it captures all relevant details, such as the reasoning behind the change, the potential impact on existing designs, timelines, and resource requirements. By documenting these proposals, the ECP ensures that any changes undergo a systematic review and approval process, which helps maintain quality control and compliance with standards.

While suggestions for enhancements to design can be part of an ECP, they do not capture the entirety of what an ECP encompasses. A checklist for engineers or an informal discussion do not provide the level of structure, detail, and formality necessary for effectively managing engineering changes. The importance of an ECP lies in its ability to create a clear, organized approach to managing alterations, ensuring that all stakeholders are informed and that modifications are implemented in a controlled manner.
