1. Management theory has evolved over time from agrarian societies through the industrial era to modern post-industrial societies. Early theories focused on hierarchical structures and scientific approaches to work. 2. Later theories incorporated human factors, recognizing the importance of employee satisfaction and informal social structures within organizations. Contingency theory emerged, asserting there is no single best approach and management must adapt to each organization's unique circumstances. 3. Current approaches include applying quantitative techniques to decision making, viewing the organization and its subsystems as part of a larger environmental system, and tailoring leadership styles to different situations.
