RACI Matrix

RACI Matrix: makes clear who does what on each task or decision — so nothing falls between the cracks.

Best for: Teams with shared work · Time: 1 hour
Domain: Resources · Focus area: Planning

How it works

A grid with tasks or decisions as rows and people or roles as columns. Each cell gets one letter describing that person’s role in that task.

• R — Responsible: does the work. At least one per task.
• A — Accountable: owns the result and signs it off. Exactly one per task.
• C — Consulted: gives input before the work is done (two-way).
• I — Informed: is kept up to date afterwards (one-way).

How to apply it

1. List the key deliverables and decisions (from the WBS) as rows.
2. List roles — not just names — as columns.
3. Fill in the letters together with the team, not alone at your desk.
4. Check the rules: exactly one A per row, at least one R; many Cs slow decisions; a column full of letters is an overloaded person.
5. Publish it and use it whenever someone asks “who decides this?”.
