According to the PMBOK® Guide, the Create WBS (Work Breakdown Structure) process is the process of subdividing project deliverables and project work into smaller, more manageable components.
The primary output of this process is the Scope Baseline. The Scope Baseline is a component of the project management plan and consists of three specific elements:
Project Scope Statement: Includes the description of the project scope, major deliverables, assumptions, and constraints.
Work Breakdown Structure (WBS): A hierarchical decomposition of the total scope of work to be carried out by the project team.
WBS Dictionary: A document that provides detailed deliverable, activity, and scheduling information about each component in the WBS.
Analysis of other choices:
Choice B (Project scope statement): While part of the scope baseline, the Project Scope Statement itself is a primary output of the Define Scope process, which occurs before Create WBS.
Choice C (Organizational process assets): These are typically inputs to the Create WBS process (such as WBS templates or policies), rather than outputs.
Choice D (Requirements traceability matrix): This is an output of the Collect Requirements process. It is used as an input to Create WBS to ensure that every requirement is linked to a specific WBS element.
In summary, because the Create WBS process " finalizes " the WBS and WBS Dictionary, it integrates them with the previously defined Scope Statement to form the Scope Baseline.
