Responsibility assignment matrix
A responsibility assignment matrix, also known as a RACI matrix (/ˈreɪsi/) or linear responsibility chart, is a project management technique that describes the responsibilities of various stakeholders in completing tasks or deliverables. The matrix assigns one of four responsibilities to each stakeholder in executing a deliverable: Responsible, Accountable, Consulted, and Informed.
Under the RACI framework:
Responsible stakeholders are involved in the planning, execution, and completion of the task;
Accountable stakeholders are held to be individually and ultimately responsible for the success or failure of the task;
Consulted stakeholders are sought for their opinions on a task;
Informed stakeholders are updated as the project progresses.
