What is the RACI/ARCI Matrix in Project Management? (#2 in the series The RACI/ARCI Matrix for Structuring Roles in Project Management)
By Swapnil Gyani

The RACI/ARCI Matrix is a responsibility assignment matrix system that brings structure and clarity to assigning the roles people play within a team. It is a simple grid system that you can use to clarify people’s responsibilities and ensure that everything the team needs to do is taken care of.

It is a system that brings structure and clarity to assigning the roles people play within a team. It is a simple grid system that you can use to clarify people’s responsibilities and ensure that everything the team needs to do is taken care of. Sounds complicated, how do I use it? Using the RACI/ARCI system, you list every task, milestone and decision, then clarify who is responsible, who is accountable, and where appropriate, who needs to be consulted or informed. The acronym RACI stands for (for ARCI you just have to flip Accountable and Responsible):

  • Responsible - these people are the “doers” of the work. They must complete the task or objective or make the decision. Several people can be jointly responsible.
  • Accountable - this person is the “owner” of the work. He or she must sign off or approve when the task, objective or decision is complete. This person must make sure that responsibilities are assigned in the matrix for all related activities. There is only one person accountable, which means that “the buck stops there.”
  • Consulted - these are the people who need to give input before the work can be done and signed-off on. These people are “in the loop” and active participants.
  • Informed - these people need to be kept “in the picture.” They need updates on progress or decision, but they do not need to be formally consulted, nor do they contribute directly to the task or decision.

Do parent activities inherit the RACI roles of the sub-activities?

For example in sub-activity 1 a person has the responsibility role, at sub-activity 2 the same person has the consulted role and at sub-activity 3 the person has the responsibility and accountability role. On the major activity level, can the sum of roles for that person be defined as C+R+A?

Hi Taro,

Good question. The short answer is “No”, RACI parent activities do not inherit the roles of the sub-activities by default.

Additionally, even RACI sub-activities (or child activities) do not necessarily inherit the roles of their parents, eg. if a person is Informed on Activity A, s/he may or may not be Informed on its child activity B. Clearly, this is not a sign of a healthy RACI matrix, but it can easily happen even with the best Project Managers.
