What does RACI stand for?

Responsible, Accountable, Consulted, and Informed. Responsible people do the work, the Accountable person owns the outcome, Consulted people give input before decisions, and Informed people are kept up to date afterwards.

Why should each activity have exactly one Accountable?

Accountability must sit with a single person so there is one clear owner for the outcome. Multiple Accountables dilute ownership and cause confusion, while none means no one is on the hook. The builder warns when this rule is broken.

Can a person be both Responsible and Accountable?

Yes. On smaller teams one person often does the work and owns the outcome. In RACI that cell is usually marked A, since Accountable implies they also drive the work; the matrix stays clean with one role per cell.

How is a RACI different from a RACI-VS or RASCI chart?

Variants add roles such as Support (S) or Verifier and Signatory (V and S). RACI is the core four-role model and is enough for most projects; the builder focuses on the standard R, A, C, and I assignments.

How do I use the exported matrix?

The export is tab-separated, so pasting it into a spreadsheet drops each value into its own cell with activities down the side and people across the top. You can then format, colour, or share it with your team.

A RACI chart that enforces single accountability

A RACI matrix makes project roles unambiguous: who does the work, who owns the outcome, who is consulted, and who is informed. This builder lays activities down the rows and people across the columns, lets you assign one role per cell, and — crucially — checks that every activity has exactly one Accountable owner.

How it works

Each row is an activity and each column is a person or role. In every cell you assign one of R, A, C, or I. The core governance rule of RACI is that an activity must have exactly one Accountable owner — one and only one A per row — so ownership is never diluted or missing. The builder counts the A assignments per row and flags any activity that has zero or more than one. When you export, the matrix is emitted as tab-separated values so it drops cleanly into a spreadsheet, with activities down the side and people across the top.

How it works in practice

Keep activities verb-led — approve budget, write spec, deploy release — so roles are obvious.
Resolve every Accountability warning before sharing; a missing or duplicate A is a real coordination risk.
Limit Consulted roles; too many C assignments slow decisions to a crawl.
Paste the tab-separated export into a spreadsheet, then colour the cells for an at-a-glance view.
