Final answer:
The statement is false; Mintzberg's model includes interpersonal, informational, and decisional roles, not formal, informal, and technical roles. Misconceptions of managerial roles can cause organizational inefficiencies and interpersonal conflicts.
Step-by-step explanation:
The statement that according to Mintzberg, managers perform three roles: formal roles, informal roles, and technical roles is false. Henry Mintzberg, a renowned management scholar, identified ten roles that a manager performs, which are grouped into three categories: interpersonal roles, informational roles, and decisional roles. Interpersonal roles include figurehead, leader, and liaison roles. Informational roles encompass monitor, disseminator, and spokesperson. Decisional roles cover entrepreneur, disturbance handler, resource allocator, and negotiator. Misconceptions about managerial roles can lead to issues like work overload, conflict, and ambiguity in defining the managerial role, or difficult work relationships within an organization.
As modern businesses like restaurants or large factories divide tasks among various jobs, the role of a business manager who handles different aspects such as paychecks and bills is crucial for efficient operations. These managerial responsibilities may lead to work overload, and the need for clear definition and awareness of these roles is essential for preventing conflicts and establishing effective work relationships.
