The PRACI matrix


Your blueprint for realisation

of a project’s objectives

The PRACI matrix is a simple yet effective means of communicating to project team members who is accountable and who is responsible for completing specific tasks while at the same time conveying to those: who are required to participate in their preparation; who will be consulted; and those that are simply to be informed. The PRACI matrix is an indispensable expansion of the pan industry RACI chart that has been in existence for several decades.


Having supported projects in multiple industries in the UK, South Africa, Malaysia, the UAE and Qatar over the last 12 years, the creation and use of the PRACI matrix has proved to be an invaluable communication and collaboration tool. It removes confusion and ambiguity.  Its construction forces a team to consider all of the tasks required to complete an activity and who should be involved. It provides transparency, visibility and lucidity. It avoids the ownership of activities ‘falling through the cracks’ where one team member has incorrectly assumed someone else is undertaking a specific task. It avoids the discovery of the need to carry out additional activities at the ‘eleventh hour’, robbing team members of ample warning of new tasks to be completed. PRACI charts can prevent reputations being tarnished when milestones are missed. Project reviews of failed projects pinpoint activities that were not identified, specialist consultants who were engaged late in a programme or stakeholders that were not consulted. Time and time again it is not until a PRACI chart is commenced that a consensus is established across a project as to the tasks to be completed and the appropriate accountabilities and responsibilities.


The adoption of a PRACI matrix has proved to be an aid to establishing project governance and the implementation of project controls. The introduction and use of a PRACI matrix is described within the text “The rules of project risk management, implementation guidelines for major projects, second edition” published by Routledge in 2020, in both New York and Oxfordshire in the UK. The text advocates that “Leadership must ensure that it is made explicit who within the project team is accountable and who is responsible for all of the primary risk management activities”. The same tenet applies to all of the other project disciplines.


The PRACI matrix is a project role and responsibility assignment chart that describes the tasks to be completed for a specific objective and assigns which roles are Accountable and Responsible for each task, which project team members are required to Participate and who needs to be Consulted or Informed. The acronym PRACI stands for the five roles that project team members play in completing activities that contribute to a collective goal.

P: Participate

Those who assist and support those who are Responsible for the completion of the task.

R: Responsible

The individual who is Responsible is subordinate to the individual who is Accountable.  Those who are Responsible are those that ‘do the work’ to achieve the task. There is typically (but not always) one individual assigned to a task who is Responsible, to avoid confusion as to which individual should deliver. A Responsible person may be responsible for completing multiple tasks.
