CompTIA Project+ (PK0-005)Project Life Cycle PhasesMedium
A project manager wants a single-page tool showing, for each task, who is Responsible for doing the work, who is Accountable for approval, who must be Consulted, and who should be Informed. Which tool should be created?
- ARACI matrix
- BWork breakdown structure
- CStakeholder register
- DCommunication plan
Show answer & explanationAnswer & explanation
Correct answer: A. RACI matrix
A RACI matrix clarifies roles and responsibilities for each task using the categories Responsible, Accountable, Consulted, and Informed. The stakeholder register lists stakeholders' interests, the communication plan defines how/when info is shared, and the WBS decomposes scope into deliverables.
Why the other options are wrong
- B. The WBS breaks down scope into deliverables, not role assignments.
- C. The stakeholder register lists stakeholder info but not task-level role assignments.
- D. The communication plan defines communication methods and frequency, not task roles.
RACI Matrix
A responsibility assignment chart identifying who is Responsible, Accountable, Consulted, and Informed for each task.
- R = Responsible (does the work)
- A = Accountable (approves/owns outcome)
- C = Consulted, I = Informed
Memory trick: RACI = 'Racing' to clarify who does what
