Which of the following is NOT one of the three main types of management roles?

In the context of management roles, the three main categories identified are interpersonal roles, decisional roles, and informational roles. Each of these categories encapsulates specific responsibilities that managers must fulfill to effectively lead their teams and organizations.

Interpersonal roles involve interaction with employees and stakeholders, fostering relationships, and ensuring teamwork and a positive organizational culture. Decisional roles focus on making choices and decisions that align with organizational objectives, such as resource allocation and conflict resolution. Informational roles entail the gathering, processing, and dissemination of information to make informed decisions and communicate effectively with various stakeholders.

The term "operational roles" does not align with the established framework of management roles, making it the correct response as it is not classified among the main categories. Understanding these roles is crucial for effective leadership, as it helps clarify the functions and expectations of managers in an organizational setting.
