The 21st century market demands of companies the ability to self-manage in order to efficiently and effectively meet the needs of each customer; Thus, to achieve these results, it is important to minimize efforts and eliminate rework. In this context, a comprehensive view that reflects the globalized scenario and technological revolution is fundamental. An example of such is the General Theory of Systems, which emerged, at the beginning of the 20th century, as a form of integration between the different areas of knowledge, generating resources for a management model that provides to the manager a holistic view of the business, focusing on the interrelationships between the organization's elements. Based on the above, this study aims to analyze the application of Systemic Theory in a Software House company in the region of Bragança Paulista. We used the case study method and bibliographic research to develop the work and participant observation in the data collection, with the development of company projects as object of study. From the analysis of the case it is possible to verify, as a benefit of the systemic management model, a tendency towards greater effectiveness in the resolution of conflicts, as well as opportunities for productivity gains, due to the holistic perception of the processes.
