Explanation:
A Responsibility Assignment Matrix (RAM), also known as RACI matrix or Linear Responsibility Chart (LRC), describes the participation by various roles in completing tasks or deliverables for a project or business process. It is especially useful in clarifying roles and responsibilities in cross-functional/departmental projects and processes. RACI is an acronym derived from the four key responsibilities most typically used:

* Responsible: Those who do the work to achieve the task. There is typically one role with a participation type of Responsible, although others can be delegated to assist in the work required.

* Accountable (also Approver or final Approving authority): The one ultimately accountable for the correct and thorough completion of the deliverable or task, and the one to whom Responsible is accountable. In other words, an Accountable must sign off (Approve) on work that Responsible provides. There must be only one Accountable specified for each task or deliverable

* Consulted: Those whose opinions are sought; and with whom there is two-way communication.

* Informed: Those who are kept up-to-date on progress, often only on completion of the task or deliverable; and with whom there is just one-way communication.
