Use, Relationships: An Engineering Change Proposal (ECP) provides the documentation in
which the engineering change is described. It includes change impacts to systems, configuration
items and other associated configuration documentation affected by the proposed change. In
addition, it typically describes how the proposed change will be implemented along with
providing estimated schedules and associated costs.
