The document discusses creating a work breakdown structure (WBS) as part of project scope management. It explains that a WBS subdivides project deliverables and work into smaller, more manageable components. It provides details on defining a WBS, including inputs like the scope management plan, project scope statement, and requirements documents. Techniques for creating a WBS involve decomposition and expert judgement. The main outputs are the scope baseline, which includes the project scope statement, WBS, and WBS dictionary, and updates to project documents.
