A recommended method to document the respective roles of groups and individuals for a given...

Explanation:

A RACI chart is a structured method to document the roles and responsibilities of individuals and groups in a process. It clarifies who is responsible, accountable, consulted, and informed for each task or decision.

This tool is widely used in project management and process optimization to eliminate ambiguity and ensure clear role delineation.

Why Other Options Are Incorrect:

A. Organization chart: An org chart shows reporting relationships but does not document process-specific roles.

B. Telephone call tree: A call tree is for communication during emergencies, not documenting roles in processes.

C. Isolinear response matrix: This option is impractical and does not address role documentation.

EC-Council CISO Reference:The program emphasizes the use of tools like RACI charts to manage role clarity in IT security operations and projects.
