RACI Matrix.

Who does, who decides, who's consulted, who's told.

↳ tl;dr

RACI clarifies decision authority for a specific deliverable or recurring decision. Responsible (does the work). Accountable (one person — owns the outcome). Consulted (input before decision). Informed (told after).

When to reach for RACI

When a decision keeps stalling, when team members repeatedly step on each other, or when work is dropping between teams. You don't need a RACI for everything — you need it where ambiguity is costing you.

Rules

  • Exactly one A per row. If everyone's accountable, nobody is.
  • R can be plural. Multiple people can do the work together.
  • C is for input before; I is told after. Don't conflate them.
  • Avoid CC'ing everyone as I. Choose who genuinely needs to know.

Variants

VariantAddsWhen useful
RACIDefault. Most cases.
RASCIS = SupportWhen a deliverable has supporting roles distinct from doing
DACID = Driver, A = Approver, C = Contributor, I = InformedCommon in product orgs; emphasizes the Driver as a distinct role
RAPIDRecommend, Agree, Perform, Input, DecideBain's variant; useful for complex multi-stakeholder decisions

the most common mistake (worth repeating)

Two A's on a single row. Once you allow shared accountability, the matrix becomes decorative. Single A or the tool is broken.
