Work Breakdown Structure (WBS) is a hierarchical decomposition of the work to be executed by the project team in order to accomplish the project objectives and deliverables. It is a visual tool that helps to organize and define the scope of the project, and break down complex tasks into smaller, more manageable pieces.
In this example, the project is building a house. The WBS is broken down into several main components: Planning, Design, Construction, Testing and Commissioning, and Project Closure. Each of these components is further divided into smaller, more specific tasks or sub-components. For instance, under the Planning component, there are several tasks such as defining project scope, identifying key stakeholders, developing project schedule, determining project budget, and obtaining necessary permits and approvals. Similarly, the Construction component is broken down.
