Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
RACI matrix
A RACI matrix defines roles and responsibilities for each task or deliverable using the four categories.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Work breakdown structure
Why it's wrong here
A work breakdown structure decomposes deliverables into manageable components; it carries no responsibility assignments. The option tempts because WBS elements are often mapped to owners, but the RACI categories belong to a responsibility assignment matrix, which the WBS itself does not define.
- ✗
Communication plan
Why it's wrong here
A communication plan specifies what information is distributed, to whom, when and by which method; it does not map roles against activities using RACI categories. The option tempts because both documents address stakeholders, but the communication plan governs information flow rather than decision rights and task ownership.
- ✓
RACI matrix
Why this is correct
The RACI matrix directly satisfies the stem's requirement for a document mapping roles and responsibilities across four defined categories: Responsible, Accountable, Consulted, and Informed. Unlike a project charter or communication plan, it assigns each task or decision to specific people using exactly these designations, making it the precise artefact described.
- ✗
Stakeholder register
Why it's wrong here
A stakeholder register records identification, assessment and engagement information about stakeholders; it does not assign Responsible, Accountable, Consulted or Informed categories to activities. The option tempts because stakeholders appear in a RACI, yet the register lacks the task-by-role matrix structure that RACI requires.
