Define the three levels of management and explain the major responsibilities of managers at each level.
The three levels of management are top managers, middle managers, and team leaders or supervisors. Top managers ensure that major performance objectives are established and accomplished in accordance with the organization’s purpose. Top managers are responsible for the performance of an organization as a whole or for one of its larger parts. Middle managers are in charge of relatively large departments or divisions consisting of several smaller work units. Middle managers report to top managers and coordinate with peers to develop and implement action plans to accomplish organizational objectives. A team leader or supervisor is someone in charge of a smaller work unit composed of non-managerial workers. Team leaders or supervisors ensure that their work teams or units meet performance objectives that are consistent with the plans of middle and top management.
