The Work Breakdown Structure (WBS) is a key tool for defining the scope of work and developing estimates for a project. It breaks down the project into smaller, manageable components, making it easier to estimate time, cost, and resources required for each task. The BABOK Guide (Chapter 5: Requirements Life Cycle Management - Prioritize Requirements) and project management best practices emphasize the use of a WBS to organize and define the total scope of the project. The WBS helps ensure that all work is accounted for and provides a clear structure for estimating and planning.
