A Work Breakdown Structure (WBS) is a project management tool that breaks down a project into smaller, more manageable components. It is a hierarchical and deliverable-oriented decomposition of the total scope of work to be carried out by the project team to accomplish the project objectives and create the required deliverables. The WBS provides a common framework for the natural development of the overall planning and control of a contract and is the basis for dividing work into manageable sections. The WBS is decomposed into work packages, which are the smallest deliverable components of a project. The WBS is a roadmap that guides project managers to the completion of a project scope. It helps with important project management process groups and knowledge areas such as project planning, scheduling, budgeting, risk management, resource management, task management, and team management. The WBS is an excellent tool for measuring project completion, identifying milestones, and allocating budget resources. There are two main types of WBS: deliverable-based and phase-based. The most common and preferred approach is the deliverable-based approach, which clearly demonstrates the relationship between the project deliverables and the scope. To create a WBS, project managers start with the end objective and successively subdivide it into manageable components in terms of size, duration, and responsibility. The WBS is a helpful diagram for project managers to visualize their project scope and allocate resources for all project tasks.
