This thesis aimed to propose an analytical model that relates the effects of control mechanisms in the formation of trust between organizations involved in alliances and partnerships, identifying their effects on performance. The study sought to fill a gap in the literature, which in most cases considers these as antagonistic or substitutes concepts and not directly related to performance. This research believes that these are complementary concepts. The methodology used was the case study of a strategic alliance between a development bank (BNDES) and 20 financial agents in a guarantee fund, which guarantees for micro, small and medium enterprises, with document analysis, semi-structured interviews and application of questionnaires with Likert type scale. The study analyses contractual, regulatory and control mechanisms instruments, the nature of formalization, the perception of implementation and its effects on the dynamics of trust at both operational and management levels of interorganizational relations. The results of contracts, regulatory, interviews and questionnaires analysis indicated that to expand its operations, the fund need to balance governance with structural perspective, based in controls mechanisms with a relational structure, based on informal mechanisms that build financial agents trust. The main contribution of this study is to clarify the relationship between trust and control in the design of interorganizational governance mechanisms. Moreover, the framework considers the organization type, respondents hierarchical level, and the previous relationship between organizations. And finally the study proposes a performance evaluation that considers not only the perceptions from the questionnaires, but also business indicators.
