Using the RACI matrix you can represent and analyze responsibilities that exist within a process. RACI is short for Responsible, Accountable, Consulted, and Informed.
The matrix shows which organizational unit participates in activities of a process and in what manner:
Responsible indicates who assumes execution responsibility. It shows who is responsible for performing an activity and who actually performs it, but also who assumes the disciplinary responsibility.
Accountable identifies the person ultimately answerable for the correct and thorough completion of a task. Thus, 'Accountable' may be the one in charge of managing the costs, that is, the one who assumes project budget responsibility. The decides on and accepts connections are evaluated in order to mark this responsibility.
Consulted shows who has a consulting role. This organizational unit - typically a group of subject matter experts - is asked for advice prior to a final decision being made or a final action being taken.
Informed specifies who must be informed. It indicates who is kept up to date on the progress or completion of a task.
