What is a Work Breakdown Structure (WBS) and its purpose?

• A. A hierarchical decomposition of the project deliverables and work into smaller components; it provides a basis for planning, budgeting, and control.
• B. A list of project risks and their severity.
• C. A chart of communication roles and responsibilities.
• D. A document listing all stakeholders.

Answer: (A)

A Work Breakdown Structure is a hierarchical decomposition of the project deliverables and the work required to produce them into smaller components, and its purpose is to provide a basis for planning, budgeting, and control. By organizing the scope into manageable work packages, it enables accurate estimation, assignment of responsibilities, scheduling, cost tracking, and performance measurement, while clarifying boundaries to manage scope changes. The other artifacts describe different aspects of a project—risks, communication roles, or stakeholder lists—but they don’t structure the work into the deliverables and tasks needed to complete the project.
