The use of a Work Breakdown Structure (WBS) is a fundamental project management tool that helps in organizing the team's work into manageable sections. The PMBOK Guide highlights that the WBS is a hierarchical decomposition of the total scope of work to be carried out by the project team to accomplish the project objectives and create the required deliverables2. By breaking down the project into smaller components, the WBS allows for more accurate and efficient planning, scheduling, and allocation of resources, which in turn reduces the likelihood of rework due to oversight or miscommunication3.
