Max Weber developed the bureaucratic theory, which describes bureaucracy as the most efficient form of organization. According to Weber's theory, a bureaucratic organization has a clear line of authority and rules that are strictly followed. It is characterized by division of labor, a hierarchy of authority, rational and consistent application of rules, selection and promotion based on technical qualifications, and defined methods for work. However, critics argue that bureaucracy can overemphasize rules at the expense of informal groups, involve excessive paperwork, and cause delays in decision-making.
