Final answer:
The project scope statement is the essential document detailing all necessary work for project completion, and it is fundamental for project costing, scheduling, and assigning responsibilities.
Step-by-step explanation:
The project scope statement is a basic project document that describes all the work that must be done to complete the project and forms the basis for costing, scheduling, and work responsibility. It lays the groundwork for the mathematical model of operation, detailing the metrics for performance and efficiency of the project's design and how well it meets the client's needs. This detailed design phase takes up a significant part of the project timeline and is crucial to the project's success, as a poorly executed detailed design can undermine a solid design concept. The scope of the project is defined through a problem definition process, which includes understanding customer needs, competitor positions, governmental or technological constraints, and available resources such as personnel, time, and money. This process culminates in the development of a clear problem statement, criteria, and constraints, ultimately reflecting the understanding of the project's scope and the resources to resolve the design problem.
