The classical approach to management originated in the early 1900s and focused on increasing efficiency through careful observation of management practices. It sought to identify universal principles for efficient operation. Some key aspects included scientific management by Frederick Taylor which aimed to increase worker output and management efficiency. Henri Fayol identified 14 general principles of management and categorized organizational work into technical, commercial, financial, accounting, security, and managerial functions. Max Weber's bureaucratic theory defined bureaucracy as a rational and efficient form of organization with characteristics like job specialization, authority hierarchies, and impersonal relationships between employees. Criticisms of bureaucracy include that it is too rigid with an overemphasis on rules and processes that can limit flexibility and human aspects.
