Few things slow a team down like a task that everyone assumes someone else owns. A deadline slips, a decision stalls, and a week later two people discover they did the same work while a third was never told. A RACI matrix prevents that. It is a simple grid that spells out who does the work, who decides, and who needs to know. This guide explains what a RACI matrix is, how to build one step by step, the mistakes that make it useless, and how to keep it current.
What is a RACI matrix?
A RACI matrix is a responsibility assignment chart. Down the left side you list tasks, deliverables or decisions. Across the top you list people or roles. In each cell you place one of four letters, or leave it blank. RACI stands for:
Responsible (R)
The people who do the work. There can be several, and every task needs at least one.
Accountable (A)
The one person who owns the outcome and gives final sign-off. If the task fails, this is who answers for it. There must be exactly one.
Consulted (C)
People whose input is needed before a decision or delivery — subject-matter experts, legal, finance. Communication runs both ways.
Informed (I)
People who are kept up to date on progress or results but do not shape the work. Communication runs one way.
On small tasks the same person can be both R and A, usually written A/R. Everyone else on that row gets a C, an I, or nothing at all.
Why bother with one?
A RACI matrix removes ambiguity before it becomes a problem. Decisions get made faster because everyone knows who has the final say. New hires can see who to ask. And because the grid makes workloads visible, it also shows who is overloaded with R's and who is quietly carrying too many A's.
How to build a RACI matrix in six steps
- Step 1: List the tasks and decisions. Start from a project plan or a recurring process. Aim for 10 to 25 meaningful rows, not every tiny action.
- Step 2: List the people or roles. Roles age better than names, so use “Marketing lead” rather than a person where you can.
- Step 3: Assign the A first. For each row, decide the one person who owns the outcome. This is the hardest and most valuable step.
- Step 4: Assign the R's. Who actually does the work? If the A is also doing it, mark A/R.
- Step 5: Add C's and I's sparingly. Ask who must be asked before the work is done, and who only needs to hear afterwards.
- Step 6: Review it with the people in it. A RACI imposed from above gets ignored. Walk through each row together and resolve disagreements in the room.
A simple example
Imagine a website redesign with four people: the marketing lead, a designer, the CEO and the sales lead.
- Approve the design brief: marketing lead A, designer R, CEO C, sales lead I.
- Produce the page designs: designer A/R, marketing lead C, sales lead C.
- Sign off the final site: CEO A, marketing lead R, designer C, sales lead I.
- Announce the launch to customers: marketing lead A/R, sales lead C, CEO I.
Notice that every row has exactly one A, and nobody is asked to be consulted on everything.
Common RACI mistakes
- Multiple A's on one task. Two accountable people means nobody is. If you cannot pick one, the task is probably too big — split it.
- No A at all. A row with only R's is a task that will drift. Every row needs an owner.
- Too many C's and I's. If everyone is consulted, decisions crawl. If everyone is informed, nobody reads the updates.
- Going too granular. A 200-row matrix will never be maintained. Group small actions into a single deliverable.
- Skipping the conversation. Assigning someone an R or an A without their agreement just moves the confusion later.
- Treating it as a one-off. A RACI drawn at kickoff and never opened again is out of date within a month.
Keeping it current
People change roles, projects change scope, and a matrix that no longer matches reality is worse than none, because it sends people to the wrong door. Review it at project milestones, whenever someone joins or leaves, and whenever a task is repeatedly escalated to the wrong person. Keep it somewhere everyone can find it, not in an attachment buried in email.
A spreadsheet works fine for a RACI, and many teams never need more. If you already run your operations in FulcrumGrid Command Center, it can help to keep ownership visible next to the projects and KPIs it relates to, so the question “who owns this?” is answered in the same place you track the work.
Build it with the team, give every row one owner, and revisit it when things change. A RACI matrix will not do the work for you, but it will make sure everyone knows whose work it is.
Frequently asked questions
Can a task have more than one Accountable person?
No. Exactly one person should be accountable for each task or decision. Shared accountability usually means nobody feels fully on the hook. If you cannot choose one, split the task into smaller deliverables.
Can the same person be Responsible and Accountable?
Yes. On small tasks the person doing the work often owns the outcome too, and it is written A/R. On larger work it is healthier to separate them so someone independent signs off.
What is the difference between Consulted and Informed?
Consulted people give input before a decision or delivery, so communication is two-way. Informed people are only updated afterwards, so communication is one-way. Keep both lists short.
How often should we update a RACI matrix?
At every project milestone, whenever team members join or leave, and whenever responsibilities shift. A quick review each quarter is a good minimum for recurring processes.
