An industry best practice for defining the level of responsibility assigned to a specific 'role' is the RACI matrix which is an abbreviation for Responsible Accountable, Consulted and Informed. Also referred to as Responsibility Assignment Model (RAM), this approach maps activities and deliverables to roles for a business process.

The IT Infrastructure Library® has supplemented the RACI model with a 5th level termed 'support'. Hence the ITIL® model has been labeled 'RASCI' which is defined below:

• Responsible (R): Resources that work to achieve a task. There is typically one role with a participation type of Responsible.
• Accountable (A): Resources accountable for the completion of the deliverable or task, and the one to whom Responsible typically reports to either directly or indirectly.
• Support (S): Resources that assist those Responsible in completing a task or activity.
• Consulted (C): Those who are not directly involved in a process but provide inputs and whose opinions are sought.
• Informed (I): Those who receive outputs from a process or are kept up-to-date on progress, often only on completion of the task or deliverable.

Although valuable in defining roles and responsibilities, RACI or RASCI models are usually implemented independently as stand-alone and are not integrated into the strategy development process for transformation or optimization alternatives.
