What common elements are included in an ECP?

An Engineering Change Proposal (ECP) typically includes a comprehensive description of the proposed change, which outlines what the change is, why it is needed, and its implications for the project. Justification is crucial as it addresses the rationale for the change, typically focusing on improvements in functionality, performance, or compliance with standards.

Cost impact is another essential element, as it assesses how the proposed change will affect the project's budget, which is vital for making informed decisions. Similarly, schedule implications are included to evaluate how the change may affect the project timeline, including any potential delays or acceleration of deliverables.

Including all of these elements ensures that stakeholders have a clear, concise summary of the change being proposed and can make an informed decision regarding implementation. The other options do not encapsulate the core elements that form the basis of an ECP necessary for evaluating changes effectively.
