Organizations are one of the characteristic elements of more modern societies. The complexity of social life and the difficulty of intended social objetives require that individuals should join their fellow men to try to achieve them. It is not easy to understand ordinary life without making continuous references to organizations, which act as extensions of man to reach certain difficult goals. The study of organizations has been a significant part of the effort exerted by social sciences to rationallize social life in the Twentieth century; it can be predicted that it will be increasingly important. Factories, companies, and organizations have often been successive ways of organizing work from the beginning of industrialization up to our days. We are ever more aware of the importance of organizations in our lives. Sociology, which paid attention to the phenomenon of factories from the very beginning, has continued to be concerned about the study of organizations. We will see here some aspects of that study.
