What is the difference between an ECP and a Request for Change (RFC)?

The distinction between an Engineering Change Proposal (ECP) and a Request for Change (RFC) centers around their levels of detail and scope. An ECP is a comprehensive document that provides detailed information about the proposed changes to a project, product, or system. It typically includes an analysis of the problem, a proposed solution, impacts on cost and schedule, and technical assessments. This in-depth nature is essential for stakeholders to make informed decisions regarding implementation.

On the other hand, a Request for Change is generally a broader initial solicitation for any type of change, which may not contain the same level of detail or analysis. It serves as a starting point to express the need for change, which may then be further developed into an ECP if deemed necessary.

Understanding this differentiation is crucial for professionals involved in engineering and project management, as it delineates the processes for initiating and evaluating changes in a systematic manner.
