Project management? Use the ARIES Matrix (with FREE template)

Blame game.


Heated arguments.

These are the things that may happen if there’s no simple, effective means for defining and documenting project roles and responsibilities.

If you’re a project manager, familiarizing yourself with the ARIES Matrix—a variant of the RACI (Responsible, Accountable, Consulted, Informed) Matrix—could increase your chances of completing your project.

ARIES Matrix is a responsibility assignment matrix (RAM):

Accountable – Person accountable for signing off the work (max. 1)
Responsible – Person responsible for doing the work
Informed – Person(s) informed of work progress/completion
Expert – Person(s) consulted before and during a task
Support – Person(s) supported to complete a task

How the ARIES Matrix works?

  1. Download the FREE ARIES Matrix Microsoft Excel file template here.
  2. List down all the tasks under the ‘Task Description’ column.
  3. List down the names of the members of your team under the ‘Roles’ column.
  4. Assign who’s Accountable, Responsible, Informed, Expert, Support for a particular task.

Take note of the following:

  • There should be only one person accountable for a task.
  • The more the messier. So avoid assigning more than two persons responsible.
  • For a task, a person may be accountable and responsible at the same time.

I provided generic examples in the FREE ARIES Matrix MS-Excel file template you can follow, and make the most out of this powerful project management tool.
