The ARCI decisions matrix is used for deciding and documenting who has the authority to make which decisions. It is especially useful when establishing new teams work agreements.


Step by step

  1. Ask everyone to list all the decision actions (e.g. make payment. sign contract, reply to email inquiries)
  2. Cluster the decision actions so you remove duplications and align on vocabulary (list the clusters as row titles)
  3. List everyone names as column titles (optionally, list roles instead of names)
  4. For each cell (row x column), decide and document the level of authority:
  • Accountable – Authorised to approve an answer to the decision.
  • Responsible – Responsible to recommend an answer to the decision.
  • Consulted – Those whose opinions are sought, and with whom there is two-way communication.
  • Informed – Those who are informed after the decision is made, and with whom there is one-way communication.

The ARCI matrix has many variations, such as RACI (changing the order of the ARCI letters), PACSI (Perform, Accountable, Accountable, Suggest, Informed), and DACI (Driver, Approver, Contributor, Informed). These are typically called RAM (Responsibility Assignment Matrix). They are all similar and very useful.
