The ultimate authority for approving or disapproving the ECP rests with whom?

The ultimate authority for approving or disapproving an Engineering Change Proposal (ECP) is typically vested in the Program Manager. This individual is responsible for overseeing the success of the project and ensuring that all changes align with project goals, budget, and timelines. The Program Manager evaluates the proposed changes and their impact not only on the technical aspects but also on the overall project management.

While entities like the Configuration Control Board (CCB) and the Procuring Contract Officer (PCO) may play significant roles in the review process of an ECP, they serve in advisory or evaluative capacities rather than having final approval authority. The CCB may assess the technical merits and implications of a change, and the PCO manages contractual aspects and compliance, but it is ultimately the Program Manager who decides whether to approve or reject the ECP based on a holistic view of the project.

The Secretariat may also be involved in high-level oversight, but it does not typically have direct decision-making power over individual ECPs in the same way that the Program Manager does. Thus, understanding the role of the Program Manager in this context is crucial for grasping how decisions are made regarding Engineering Change Proposals.
