A decision-rights framework that assigns four roles to every task or decision: Responsible (does the work), Accountable (owns the outcome and has final say), Consulted (must be asked before the decision), and Informed (must be told after the decision). A common failure pattern is having multiple Accountables, which guarantees deadlock — by definition exactly one person is Accountable. RACI is most useful when introduced lightly: a one-line annotation in a project plan or in the meeting notes for a contentious decision. Overapplied, it becomes bureaucratic theater. Underapplied, teams discover three weeks later that nobody actually owned the migration and it's now blocking the launch.
