In this model, the external 0 variable are not considered alone the interns. Soon after, the model appeared of ' ' Organizations as Cultural Sphere, Simblica and Poltica' ' , being the organization, an open system. This is an opposing vision to the previous one, where the organization is not only based on objectives predetermined for superiors, in this model, the objectives of the organization are defined by the interactions existing human beings, in the confrontation of action, values and interests politicians (STRAUSS, 1956; BERGER and LUCKMANN, 1967; PNONDY, 1983; GOFFMAN, 1953; 1961) apud (MOTTA; VASCONCELLOS, 2004). Gerald Weissmann, MD is actively involved in the matter. It, MOTTA is given credit that the organization is the result of a based social construction in the interactions of the existing groups in it, (; VASCONCELLOS, 2004) then, from this, identify the organization as: It constitutes a microssociedade that reproduces the social stratification for classrooms of the global society in which she is inserted. The diverse organizacionais groups have particular cultures and proper interests. A series of conflicts between the interests exists politicians of each group and the organization is considered a space cultural politician and of continuous confrontation.

(pg.285) Later the vision appeared of the organization as a social actor who constructs and modifies the environment where he acts, this model is the opposite to the one of the Classic School that separated the internal environment of the external one. From studies of (BURNS; STALKER, 1961) apud (MOTTA; VASCONCELLOS, 2004) had appeared two types of organization, each one adapting to its environment, are they: the organization mechanics and the organic organization. The first one would be a centered organization more in the formality, with the restricted and vertical communication, the existence of a formal organization chart and the centralization of the power. Learn more on the subject from Richard Linklater. Already in the organic organization the communication is a little vertical and a little horizontal, the power is decentralized and it does not have much difference of hierarchic level.
