Step-by-step explanation:
Interpersonal, informational, and decisional are the broad three types of roles that managers play within an organization according to Henry Mintzberg's managerial role theory. The interpersonal role involves interactions with employees and other stakeholders, where a manager acts as a figurehead, leader, and liaison. The informational role involves processing, sharing, and analyzing information, where a manager acts as a monitor, disseminator, and spokesperson. Lastly, the decisional role includes making decisions that affect the organization, where the manager plays the part of an entrepreneur, disturbance handler, resource allocator, and negotiator. These roles are crucial in understanding how managers contribute to the functioning and success of an organization.
