RACI Matrix

Definition

The RACI Matrix is a responsibility assignment tool that clarifies who does what in a project or process by defining four key roles:

• R – Responsible: Person(s) who do the work to complete the task.
• A – Accountable: Person who owns the outcome and has the final decision-making authority.
• C – Consulted: Person(s) whose input is required before a decision or action is taken.
• I – Informed: Person(s) who must be kept updated on progress or decisions.

Benefits

• Eliminates role confusion and overlapping responsibilities
• Improves accountability and decision-making speed
• Facilitates cross-functional alignment in Lean projects
• Helps identify gaps or overloads in responsibility distribution
