There are several theories that examine an organization and its approach to managing work with the goal of developing efficiency and increasing production. Two classic approaches to management are Taylor's scientific management theory and Weber's bureaucratic management theory. Both men are considered pioneers in the study of management. Taylor's scientific approach is based on planning work to achieve efficiency, standardization, specialization and simplification. Factories are managed by scientific methods and productivity increases due to mutual trust between management and workers. Weber's bureaucratic approach embellishes scientific management theory and focuses on dividing organizations into hierarchies, establishing strong lines of authority and control. Weber believed that organizations are responsible to and part of a larger social order. With Taylor's scientific approach, decisions are based on science or exact measurements. Estimates made for convenience are inaccurate and ineffective. Each job is broken down into smaller functions, analyzed internally and timed to the nearest tenth of a second. Through the use of a scientific method, the best possible way to accomplish a function is established and practiced until a better method or tool is designed. Similarly, in Weber's bureaucratic approach, organizations are divided into different levels, each varying in its function. degrees of influence. With each unit controlled by the one above it, a system that promotes stability and has a predictable line of communication. Both management approaches rely heavily on regulated control. Whether it is scientifically directing the task of people with authority. A strong form of control must be applied and not the philosophy of bureaucratic management. Although there are some differences between bureaucratic and scientific management theories, in reality they both share a deliberate and detailed approach to improving the efficiency and effectiveness of an organization. The differences observed in these approaches may be mainly due to their reference points. Where the scientific approach mainly focuses on maximizing work efficiency, the bureaucratic approach focuses on structuring personnel within the organization. Although both management theories have weaknesses, time has shown each to be an effective model. These two classic management approaches complement each other and are well suited to large organizations. Both theories were universally adopted and adaptations of each are put into practice today..
