Decomposition

[jyotimayank]

Yes the correct answer is option D.

PMBOK® Guide Fifth Edition defines Work Breakdown Structure (WBS) as

“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 deliverables”

Decomposition is a technique used for dividing and subdividing the project scope and project deliverables into smaller, more manageable parts. The work package is the work defined at the lowest level of the WBS for which cost and duration can be estimated and managed. The level of decomposition is often guided by the degree of control needed to effectively manage the project. The level of detail for work packages will vary with the size and complexity of the project.The WBS may be structured as an outline, an organizational chart, or other method that identifies a hierarchical breakdown. Verifying the correctness of the decomposition requires determining that the lower-level WBS components are those that are necessary and sufficient for completion of the corresponding higher-level deliverables. Different deliverables can have different levels of decomposition.
