What is Work Breakdown Structure (WBS) in Project Management
The PMBOK® Guide (3e) defines Work Breakdown Structure as “a deliverable-oriented hierarchical decomposition of the work to be executed by the project team to accomplish the project objectives and create the required deliverables. It organizes and defines the total scope of the project. Each descending level represents an increasingly detailed definition of the project work. The WBS is decomposed into work packages.
