Scope Baseline
The scope baseline is the approved version of the project scope statement, work breakdown structure (WBS), and its associated WBS dictionary, used as a reference for measuring project scope performance.
Explanation
The scope baseline is one of three baselines (along with the schedule baseline and cost baseline) that make up the performance measurement baseline of the project. It is established as an output of the Create WBS process and represents the approved scope against which all future scope-related performance is measured.
The three components of the scope baseline are the project scope statement (what the project will deliver and its boundaries), the WBS (the hierarchical decomposition of the total scope), and the WBS dictionary (the detailed description of each WBS element). Together, these documents provide a complete, approved picture of the project scope.
Changes to the scope baseline must go through the Perform Integrated Change Control process. Any approved change results in an updated scope baseline, which then becomes the new reference point. Unapproved changes to the scope baseline constitute scope creep and undermine the project manager ability to track and control scope performance.
Key Points
- •Consists of the scope statement, WBS, and WBS dictionary
- •Established during the Create WBS process
- •Used as the reference for measuring scope performance
- •Changes require approval through integrated change control
Exam Tip
The scope baseline has exactly three components: scope statement, WBS, and WBS dictionary. This is a frequently tested fact. Do not confuse the scope baseline with the project management plan.

Create WBS is the process of subdividing project deliverables and project work into smaller, more manageable components.
Project Scope Statement
The project scope statement is a detailed description of the project scope, major deliverables, assumptions, and constraints that provides a documented basis for making future project decisions.
Work Breakdown Structure (WBS)
A work breakdown structure (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.
WBS Dictionary
The WBS dictionary is a document that provides detailed deliverable, activity, and scheduling information about each component in the work breakdown structure.
Control Scope
Control Scope is the process of monitoring the status of the project and product scope and managing changes to the scope baseline.
