Tasks / deliverables (rows)
The activities, decisions, or deliverables that need clear ownership. List them down the left side of the board. Be specific: 'write the technical spec,' 'approve the budget,' 'send the client update' — not 'work on the project.' Granularity matters.
Roles / people (columns)
The roles or people involved in the project, listed across the top. Use roles rather than names where possible — RACIs based on names break every time someone changes jobs. Each intersection gets an R, A, C, I, or is left blank.
R — Responsible
Who does the work. The person actually performing the task. There can be more than one Responsible per task, but if there are too many, no one is really responsible. Every task must have at least one R.
A — Accountable
Who owns the outcome. The one person who is ultimately answerable for whether the task gets done correctly. There must be exactly one A per task — if there are two, there are zero. The Accountable person delegates to the Responsible person and is the decision-maker if conflict arises.
C — Consulted
Who must be asked before the task is completed. Two-way communication — their input affects the output. Keep this list small: too many Consulted roles create bottlenecks and approval chains that slow everything down.
I — Informed
Who is notified after the task is complete or a decision is made. One-way communication — they receive information but don't provide input. Moving someone from Consulted to Informed can dramatically speed up a project.
