This document summarizes the theories of several influential thinkers in management and organizational theory, including:
- Henry Fayol, who developed 14 principles of management and identified 5 main management functions: planning, organizing, commanding, coordinating, and controlling.
- Max Weber, who introduced the concept of bureaucracy as an efficient and rule-based form of organization, with characteristics like hierarchy, management by rules, functional specialization, and employment based on technical qualifications.
- Elton Mayo, who led the Hawthorne Studies which concluded that psychological and social factors are more important than physical conditions or financial incentives in motivating workers, in what became known as the Hawthorne Effect.
