What is a hierarchically organized depiction of the identified project risks arranged by risk category?

Question

Options

• ARisk register
• BRisk breakdown structure (RBS)
• CRisk management plan
• DRisk category

• A
  6% (1)
• B
  71% (12)
• C
  6% (1)
• D
  18% (3)

Explanation

Risk Breakdown Structure (RBS) is correct because it is specifically defined as a hierarchical representation of risks organized by category - it visually decomposes project risks in a tree structure, much like a Work Breakdown Structure (WBS) does for project work, making patterns and concentrations of risk easy to spot.

• A (Risk Register) is wrong - it's a document that logs individual risks with details like probability, impact, and response plans, but it's a list/table, not a hierarchy organized by category.
• C (Risk Management Plan) is wrong - it describes how risk management will be conducted (processes, roles, tools), not a structured depiction of the risks themselves.
• D (Risk Category) is wrong - a risk category is simply a grouping label (e.g., "Technical," "External"), not a hierarchical depiction; it's one component within an RBS, not the structure itself.

Memory tip: Think "RBS = WBS for risks." Just as a WBS breaks work into a hierarchy, the Risk Breakdown Structure breaks risks into a hierarchy by category - same shape, different subject.
