Raci Matrix
A RACI matrix is a responsibility assignment chart that defines who is Responsible, Accountable, Consulted, and Informed for project activities or deliverables.
“A matrix describing the participation by various roles in completing tasks or deliverables for a project or process. It is especially useful in clarifying roles and responsibilities. RACI is an acronym derived from the four key responsibilities most typically used: Responsible, Accountable, Consulted, and Informed.”

The RACI matrix clarifies team responsibilities, improves communication, and reduces confusion by assigning clear ownership for each task.
Responsibility definition: Every activity has assigned roles.
Improved communication: Stakeholders know their involvement.
Project governance: Helps prevent ownership gaps.
Real World Example
A regulated product team is preparing a release where Raci matrix appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Raci matrix as interchangeable with nearby ISTQB terms. That makes test scope blurry and can lead to weak evidence for the release decision.
The tester anchors the discussion in the official definition, asks where the concept appears in the product, and designs examples that show the difference between Raci matrix and similar ideas.
The page becomes useful in practice because Raci matrix is connected to a specific testing decision, not memorized as a detached definition.
