Assigning roles for each task is essential to keep a project running smoothly. The document that does this is a responsibility assignment matrix, commonly called a RACI matrix. It maps tasks to four roles: Responsible (the person who does the work), Accountable (the person ultimately answerable for the task), Consulted (those who provide input), and Informed (those who receive updates). This setup clarifies who has ownership, who approves, who must be consulted, and who needs to be kept in the loop, preventing confusion or duplicate effort. Calendar-like calendars show deadlines, budget charts focus on cost, and a risk impact matrix assesses risk—not who handles the tasks—so they don’t define roles the way a RACI matrix does.
