WBS is an acronym for which term?

• A. Waveform Baseline System
• B. Work Breakdown Structure
• C. Work Budget Schedule
• D. Work Breakdown Standard

Answer: (B)

A Work Breakdown Structure is a structured method for breaking a project’s scope into smaller, more manageable pieces called work packages. This decomposition makes planning, budgeting, and scheduling more effective because costs and resources can be estimated and tracked at the appropriate level of detail, and responsibilities can be clearly assigned. The acronym reflects the standard term used in project management for organizing work and linking deliverables to the plan, which is essential for cost control and performance measurement.

Other phrases listed aren’t recognized as the standard term for this concept in project management. They do not describe the formal framework used to organize and manage work as precisely as this term does.
