An authority matrix is often used within organizations to indicate specific roles and responsibilities in relation to Processes and activities.
The RACI model is an example of an authority matrix. It is probably one of the most widely used Authority Matrices in the IT Industry. It is used to map the Process activities to the Roles involved in their execution. The acronym RACI is derived from the distinct ways a Role can be involved in a Process.
• R – Responsible – The Person who is going to do the work/activity – Ex: Team Member
• A – Accountable – The person who owns the Activity - Ex: Project Manager
• C – Consulted – The person who may provide inputs for the Activity – Ex: Technical Architect
• I – Informed – The person who needs to be informed of the work/activity – Ex: Project Sponsor or PMO
Within the RACI model, each activity must have a role identified as Accountable and Responsible, whereas Consulted and Informed are optional. There must be exactly one Accountable role for each activity.
Generic roles are normally used in the RACI model, but it is vitally important that the Role - Activity links it describes are mapped back to specific individuals within the organization.
Separating the role involvement from the organization allows flexibility in the application of Role - Activity relationships to the realities and constraints of organizational design:
• It recognizes that the same Process (or activity) may be carried out by more than one organizational role or unit.
• It allows organization design to change without impacting the underlying process model.
• It recognizes constraints of geographically diverse organizations which may have to combine many responsibilities in fewer roles in smaller sites.
• It allows for complex organizations covering diverse businesses to adopt the same underlying process model without extensive adaptation.
