4.2.3.1 Project Management Plan
The project management plan is the document that describes how the project will be executed, monitored, and controlled. It integrates and consolidates all of the subsidiary plans and baselines from the planning processes.
Process: 4.5 Perform Integrated Change Control
Perform Integrated Change Control is the process of reviewing all change requests; approving changes and managing changes to deliverables, organizational process assets, project documents, and the project management plan; and communicating their disposition. It reviews all requests for changes or modifications to project documents, deliverables, baselines, or the project management plan and approves or rejects the changes.
Key Benefit: The key benefit of this process is that it allows for documented changes within the project to be considered in an integrated fashion while reducing project risk, which often arises from changes made without consideration to the overall project objectives or plans.

4.1.1.1 Project Statement of Work
The project statement of work (SOW) is a narrative description of products, services, or results to be delivered by a project. For internal projects, the project initiator or sponsor provides the statement of work based on business needs, product, or service requirements. For external projects, the statement of work can be received from the customer as part of a bid document, (e.g., a request for proposal, request for information, or request for bid) or as part of a contract. The SOW references the following:
Business need. An organization's business need may be based on a market demand, technological advance,

legal requirement, government regulation, or environmental consideration. Typically, the business need and the cost-beneft analysis are contained in the business case to justify the project.
Product scope description. The product scope description documents the characteristics of the product,

service, or results that the project will be undertaken to create. The description should also document the relationship between the products, services, or results being created and the business need that the project will address.
Strategic plan. The strategic plan documents the organization's strategic vision, goals, and objectives and

may contain a high-level mission statement. All projects should be aligned with their organization's strategic plan. Strategic plan alignment ensures that each project contributes to the overall objectives of the organization.
