What is a Responsibility Assignment Matrix (RAM) in Project Management?

A responsibility assignment matrix (RAM) in project management, also known as a RACI chart or RACI matrix, details all the necessary stakeholders and clarifies responsibilities amongst cross-functional teams and their involvement level in a project. RACI stands for responsible, accountable, consulted, and informed.

A RAM in project management should be referred to by all parties throughout a project because it helps plan each individual’s roles and responsibilities before work begins. A RACI matrix ensures all stakeholders involved know who is responsible when it comes time to complete a task or get feedback on deliverables.

The four roles are broken down as follows:

  • Responsible: The person(s) who is completing the task
  • Accountable: The team member who is coordinating the actions, making decisions, and delegates to those responsible for the task
  • Consulted: The person(s) who will be communicated with regarding decisions and tasks
  • Informed: The person(s) who will be updated during the project and upon completion
