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.

Reference: 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

accessible without membership, it is recognized in the business analysis community that the RACI

Matrix is a standard tool for stakeholder classification4.
