The Scope Baseline is the approved version of a scope statement, work breakdown structure (WBS), and its associated WBS dictionary. Scope baseline can be changed only through formal control procedures and is used as a basis for comparison. Scope baseline is a component of the project management plan. Scope baseline includes;
Project Scope Statement The Project Scope Statement contains the description of the project scope, major deliverables, assumptions, and constraints.
Work Breakdown Structure The WBS is a hierarchical decomposition of the total scope of work to be carried out by the project team to accomplish the project objectives and create the required deliverables. Each descending level of the WBS represents an increasingly detailed definition of the project work. The WBS makes work more manageable for the team.
WorkPackage The Work Package is the lowest level of the WBS with a unique identifier. By assigning each work package to a control account and establishing a unique identifier for that work package from a code of accounts, Work Package is finalized. These identifiers provide a structure for hierarchical summation of costs, schedule, and resource information.
Planning Package One or more Planning Packages are included in a control account. A planning package is a work breakdown structure component below the control account with known work content but without detailed schedule activities.
WBS Dictionary The WBS dictionary is a document that provides detailed deliverables, activity, and scheduling information about each component in the WBS. The WBS dictionary is a document that supports the WBS.
