In project management, what describes a hierarchical breakdown of a project into smaller tasks and activities?

• A. Gantt Chart
• B. Work Breakdown Structure (WBS)
• C. Network Diagram
• D. Critical Path Method

Answer: (B)

A Work Breakdown Structure is a hierarchical decomposition of the project into smaller tasks and activities. It starts with the final deliverables and breaks them down into components and work packages until each piece is small enough to estimate, assign, and manage. This structure clarifies what work is in scope, supports accurate cost estimates and resource planning, and provides a clear basis for scheduling and progress tracking. Other tools focus more on how and when work is done: a Gantt chart shows timing and duration in a timeline view, a network diagram maps dependencies and sequencing, and the Critical Path Method identifies the longest path of dependent tasks to determine the project’s minimum completion time. So the hierarchical breakdown described is the Work Breakdown Structure.
