Which document defines the roles and responsibilities of stakeholders in a project and is often presented as a matrix?

Correct answer & explanation
✓
RACI matrix
The RACI matrix (Responsible, Accountable, Consulted, Informed) is the correct document because it explicitly defines stakeholder roles and responsibilities in a project and is presented as a matrix format. This aligns with the PMBOK Guide and the PK0-005 exam objectives for Tools and Documentation, where the RACI matrix is the standard tool for clarifying participation levels across project tasks.
