Abstract:

In this study, it is aimed to study management and organization theories by reviewing literature, in terms of structural factors affecting decision-making process. The factors affecting decision-making are individual, structural and environmental factors. In the scope of structural factors, there are some elements such as hierarchic structures and formalization levels of organizations, authority, division of labor, specialization, centralization, delegation of authority, participation and coordination. It has been determined that the Classical theories in mechanical structure include more centralized, routine and programmable decision-making structures which are also concentrated on higher level and that the Neoclassical theories include routine, programmable, more operational organizational structure in lower levels, which is suitable to individual and group decisions. It has been concluded that the programmable and nonprogrammable decisions according to conditions, and individual and group decisions can be made together in Modern theories with the effects of environmental variations but in the contemporary managerial structures, non-programmable decisions are come to the forefront, and group decisions are put more emphasis on, and various numerical models and computer programs are utilized in order to make accurate decisions faster, because of increase in uncertainties. In recent years, new management models are developed, which enable all stakeholders participate in decision-making process
