Which of the following tools defines roles and responsibilities?

The RACI matrix is a well-known tool used to clarify roles and responsibilities within a project or process. By breaking down various tasks into four specific categories—Responsible, Accountable, Consulted, and Informed—RACI provides a clear framework for defining who is responsible for what, who has the final accountability for each task, who should be consulted for input, and who needs to be kept informed about progress.

This structured approach helps eliminate ambiguity regarding team members' roles and ensures everyone understands their specific contributions and obligations. This clarity is crucial for effective communication and collaboration within teams, fostering an environment where tasks can be executed efficiently without overlap or confusion.

In contrast, the other options, while valuable in their own contexts, do not primarily focus on defining roles and responsibilities. The Six Sigma approach is largely about improving processes and reducing defects. Balanced scorecard reporting is a strategic management tool that measures organizational performance across various perspectives. Pipeline management is a method used primarily in sales and project management to track and manage potential deals or projects, not specifically in defining individual roles within a team.
