for MBO to be effective, individual managers must understand the specific objectives of their job and how those objectives fit in with the overall company goals set by the board of directors. As Drucker wrote, “A manager’s job should be based on a task to be performed in order to attain the company’s goals…the manager should be directed and controlled by the objectives of performance rather than by his boss.”Drucker, P. (1974). Management: Tasks, responsibilities, practices. London: Heinemann. The managers of an organization’s various units, subunits, or departments should know not only the objectives of their unit but should also actively participate in setting these objectives and make responsibility for them. The review mechanism enables the organization’s leaders to measure the performance of the managers who report to them, especially in the key result areas: marketing, innovation, human organization, financial resources, physical resources, productivity, social responsibility, and profit requirements.
