What is Responsibility Matrix?
A responsibility matrix is a tool used to define and clarify the roles and responsibilities of individuals or groups in a project or process. It is a matrix that defines four different roles that individuals or groups can have when working on a project: Responsible, Accountable, Consulted, and Informed.
The Responsibility Matrix defines four different roles that individuals or groups can have when working on a project, including:
- Responsible: the person or group responsible for completing a task or activity.
- Consulted: the person or group who provides input or advice on the task or activity.
- Accountable: the person or group that is ultimately accountable for the task or activity. This person is often referred to as the decision-maker.
- Informed: the person or group who is kept informed of the progress or outcome of the task or activity.
As its acronym, the Responsibility Matrix is also known as a RACI matrix or RACI chart.
A Responsibility Matrix can be presented in a table format, where the tasks or activities are listed on one axis and the roles or individuals are listed on the other axis. The matrix indicates the level of involvement and responsibility for each role in completing each task or activity.

The purpose of a Responsibility Matrix is to ensure that everyone involved in a project or process understands their roles and responsibilities, and that there is clarity and accountability for each task or activity. The Responsibility Matrix can help to prevent misunderstandings, confusion, and delays, and ensure that tasks are completed on time and to a high standard.
