According to the PMBOK® Guide, the Work Breakdown Structure (WBS) is 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.

Structure: The WBS organizes and defines the total scope of the project and represents the work specified in the current approved project scope statement. It is typically displayed as a tree structure or an outline.

The 100% Rule: The WBS includes all work defined by the project scope and captures all deliverables—internal, external, and interim. The lowest level of the WBS is the work package, which is the point at which cost and duration can be estimated and managed.

Visual Identification: While the specific diagram was not rendered in your text, standard PMI exam questions for this number (622) provide a chart showing a project name at the top, followed by major deliverables (Level 2), and further subdivisions into smaller components. This is the classic visual representation of a WBS.

Analysis of Other Options:

A. Risk breakdown structure (RBS): While also hierarchical, the RBS is used to categorize potential project risks by source (e.g., Technical, External, Organizational) rather than decomposing the project ' s physical deliverables.

B. Project team: This would be represented by an Organizational Chart or a Resource Breakdown Structure, showing reporting relationships or resource types, not the decomposition of work.

C. SWOT Analysis: This is a technique used in project initiation and risk identification to evaluate Strengths, Weaknesses, Opportunities, and Threats. It is typically represented as a four-quadrant grid, not a hierarchical tree.
