A responsibility assignment matrix is used to correlate the project organizational structure to which document?

• A. Work breakdown structure
• B. Project charter
• C. Risk management plan
• D. All of the above

Answer: (A)

A responsibility assignment matrix connects project roles to the work that each component of the project delivers, using the work breakdown structure as the reference. The WBS defines the deliverables and work packages, so assigning who is responsible, accountable, consulted, or informed for each element helps ensure clear ownership and avoids gaps or overlaps. The project charter and risk management plan serve different purposes—goals, authority, and risk processes—not the day-to-day ownership of deliverables. That’s why the mapping centers on the work breakdown structure.
