Detailed explanation-1: -A work breakdown structure (WBS) represents a logical decomposition of the work to be performed and how the product, service, or result is naturally subdivided. The development of a work breakdown structure is an interim step to define detailed work packages used to estimate the project schedule and budget.

Detailed explanation-2: -WBS is the process of subdividing project deliverables and project work into smaller, more manageable components. The key benefit of this process is that it provides a structured vision of what has to be delivered. The WBS organizes and defines the total scope of the project.

Detailed explanation-3: -Expert Answer Here, the breaking down of tasks means the project tasks are decomposed into several small tasks to increase productivity. Thus the WBS tool applies decomposition to the tasks and not a composition. Thus option b is not true. WBS structure is carried out as deliverables-based or phases-based.

Detailed explanation-4: -The primary purpose of the WBS is too plan the schedule for the project. Each task duration is planned in conjunction with its required predecessors and following tasks. The WBS then provides an overall plan so that the project manager can see how the project should progress and manage the workflow appropriately.
