About the RACI Matrix Generator
Build a RACI matrix (responsibility assignment matrix): a grid of tasks on the rows and roles on the columns. Each cell is one of R (Responsible, does the work), A (Accountable, owns the result), A/R (the Accountable role also does the work), C (Consulted, before the work) or I (Informed, after it). The tool checks every task against the usual rules — exactly one Accountable, at least one Responsible — counts each role’s workload and lists any role with no part in any task.
Everything stays in your browser. The matrix saves automatically to this browser, so it survives a reload; export it as a CSV that re-imports here or opens in any spreadsheet, or as a PNG to drop into a deck or a document.
How to use it
- Name the project in the Title box and the roles across the columns (e.g. Sponsor, Project manager, Designer, Developer, QA, Marketing).
- For each task on a row, click a cell to cycle through —, R, A, A/R, C, I. Give exactly one role A per task, and at least one R (or an A/R that is both).
- Open Issues to see what each task is missing (no Accountable, two Accountables, no Responsible), and Workload to see what each role carries.
- Add roles and tasks with the plus buttons; move a task up or down with the ▲ and ▼ buttons next to its name, and remove one with the × at the end of its row.
- Copy summary, CSV or PNG to share. Paste a saved CSV back under Load a matrix to continue where you left off.
Examples
Approve budget — Sponsor A/R · PM C · Marketing I Gather requirements — Sponsor C · PM A · Designer R · Developer C · QA C · Marketing C Design the pages — Sponsor I · PM A · Designer R · Developer C · Marketing C Build the site — PM A · Designer C · Developer R · QA C Test and fix — PM A · Designer I · Developer R · QA R Write launch content — Sponsor I · PM C · Designer C · Marketing A/R Launch — Sponsor A · PM R · Designer I · Developer R · QA I · Marketing I Track results — Sponsor I · PM A · Marketing R
Workload: PM accountable 5, responsible 1 — a sign the PM is on the critical path. Marketing accountable 1, responsible 2.
No Accountable: pick one owner · Two Accountables: keep one, make the others R or C · No Responsible: someone has to do the work (A/R if the Accountable does it)
Common uses
- Agree who does what at the start of a project before writing a line of code or picking a venue.
- Spot an overloaded role (too many As) before a sprint or a launch.
- Make an operations handbook: one RACI per recurring process (closing the books, releasing a build, publishing a newsletter).
- Share a reviewed RACI with a sponsor as a CSV they can mark up.
What each letter means
- R — Responsible: does the actual work on the task.
- A — Accountable: the one role answerable for the result; approves the work. Exactly one per task.
- A/R — Accountable and Responsible: the Accountable role also does the work. Common on small teams.
- C — Consulted: asked for input before the work; two-way communication.
- I — Informed: told about progress or the outcome; one-way communication.
The convention is set out in the PMI PMBOK® Guide under the Responsibility Assignment Matrix (RACI chart). RASCI and DACI are variants: this tool uses the plain RACI letters, with A/R for the common case where the Accountable role also does the work.
The rules the matrix is checked against
- Exactly one Accountable per task. If no one is Accountable, pick the one owner (A, or A/R if that role also does the work). If more than one is, keep one and make the others Responsible or Consulted.
- At least one Responsible per task. Someone has to do the work. If the Accountable role also does it, mark the cell A/R rather than add a second role.
- Every role has a part in at least one task. A role with no R, A, A/R, C or I is extra: either remove it or give it a part.
- Every role has its own name. Duplicate names make the matrix ambiguous.
- Every task has a name. Rows with cells but no name are flagged so you can label them before sharing.
The tool runs these checks after every edit and shows a count of the tasks that still need a fix.
Workload by role
For each role the tool counts how many tasks it is Responsible for (R), Accountable for (A), Consulted on (C) and Informed about (I), and how many tasks it has any part in. The counts are a quick sanity check: a role with far more As than anyone else is a bottleneck, a role with only Is adds overhead, and a role with no part at all does not belong on the matrix.
Importing and sharing
The CSV has a header row with Task first, then each role, and a final Issues column so the file is self-explaining in Excel or Google Sheets. The tool reads any sheet with the same shape (letters, words such as “Responsible”, slashes and commas such as “A/R” or “R, A”, and “—” or an empty cell for “not involved”). The Issues column, if present, is left out when re-importing.
The PNG is the grid as a picture — the project title, one tinted chip per cell and a legend — drawn in your browser at twice the screen resolution, always on a white background so it reads the same in a slide, a printout or an e-mail. Tasks that still break a rule are named in red. A very large matrix cannot be drawn in one picture; the tool says so and the CSV holds everything.
Limitations
- The matrix is editorial, not an audit of what happens: it only checks that the rules are followed, not whether the right person is Accountable.
- No workflow or notifications: this is a document, not a project tool. For bigger plans use a dedicated tracker.
- RASCI, DACI and PACSI are not built in — map Support to Consulted, Driver to Responsible, and so on, before entering the matrix.
Privacy
Everything stays in your browser. The matrix is kept in this browser only (localStorage); nothing is uploaded or shared until you download or copy it.
Frequently asked questions
Can a task have two Accountables?
No. Accountability is the one role answerable for the result. Two As turn into no clear owner, so the checker flags the task and asks you to keep one.
What does A/R mean on this matrix?
Accountable and Responsible at once: the role that owns the result also does the work. It is the normal convention on small teams and in templates such as PMI’s.
How do RASCI, DACI and PARIS compare?
They add letters for Support (RASCI), a Driver and Approver (DACI) or Perform / Accountable / Review / Input / Sign-off (PARIS). The underlying idea is the same: one owner per task and a clear doer. Map the extra letters to the closest RACI role before entering them here.
Does the tool keep my matrix between visits?
Yes, in this browser only (local storage), never on a server. Clearing your browser’s site data removes it, and Reset replaces it with the example matrix. Download a CSV to keep a copy elsewhere or to open it on another device.
Can I share the matrix with a non-technical colleague?
Two ways: the PNG drops straight into a slide, a document or a chat; the CSV opens in Excel, Google Sheets or Numbers unchanged, so a reviewer can mark it up and send it back for you to re-import.
