RACI Matrix: Complete Guide With Examples

Quick answer

A RACI matrix maps every task to four roles — Responsible (does), Accountable (owns, one per row), Consulted (asked before), Informed (told after) — so every deliverable has exactly one owner.

The letters

R = does the work; A = accountable for it (one per row); C = consulted before the work; I = informed after.

Building it

List tasks/deliverables down the side, roles across the top, letters in the cells — one A per row, at least one R.

The checks

No row without an A; no column empty (unused role); no row all C/I (nobody doing it).

Using it

At planning, on role changes, when ‘who owns this?’ arises — keep it where the team looks.

Bottom line

A RACI matrix maps every task to four roles — Responsible (does), Accountable (owns, one per row), Consulted (asked before), Informed (told after) — so every deliverable has exactly one owner.
