Scope definition details the process for developing the project’s scope statement. The scope statement includes constraints, assumptions, exclusions, deliverables and acceptance criteria. It also details what related or implied work will not be performed as part of the defined project. The scope definition process starts with reviewing key project documents such as procurement scope statements, work breakdown structure, the Project Charter, Stakeholder Register, and Preliminary Scope Statements for identifying scope elements. Project scope must be communicated with the Project Sponsor and key stakeholders so there is a common understanding about what the project will or will not address. As time progresses the project’s scope becomes clearer, more specifically defined through the elaboration of comprehensive requirements, input from subject matter experts, technical support, business applications, and accepted scope changes. The project’s base lined scope should answer the project’s requirements.
