What tool classifies stakeholders according to responsibility?

 The RACI Matrix is a tool used in business analysis to classify stakeholders according to their responsibility in a project. RACI stands for Responsible, Accountable, Consulted, and Informed. Each letter represents a level of task responsibility. The RACI Matrix clarifies the roles and responsibilities of stakeholders in a project, ensuring that everyone knows what is expected of them. This helps in avoiding confusion and overlapping of duties among stakeholders.

The use of the RACI Matrix as a tool for classifying stakeholders according to responsibility is supported by various resources on stakeholder analysis and business analysis best practices123. While the BABOK® Guide itself is a proprietary resource of the IIBA and not publicly accessible without membership, it is recognized in the business analysis community that the RACI Matrix is a standard tool for stakeholder classification4.
