Business vision is often achieved through projects execution. In this context, two approaches can contribute decisively to avoid wasting resources and to increase the level of success of projects: success management and knowledge management. Although recognized as important, their joint use is practically unexplored, neither in the literature nor in organizations. The purpose of this work is to propose an integrative model of these two approaches, in order to increase the maturity of the processes and to promote the success of projects. As a result of a research in progress, a integrated model is proposed, considering success management and knowledge management practices. The work contributes with a new perspective to the management of success, allowing its results to be integrated into the general body of knowledge of the organization on the basis of a continuous cycle of evolution.
