A point that has generated discussion in the literature is the level of integration required for the coordination of activities between areas. However, there is a lack of theoretical definitions and field studies that explain this phenomenon in depth. Thus, this study aims to characterize the level of crossintegration, the factors that generate it and the impacts on organizational performance. For this, interviews with managers of Operations, R&D and Marketing/Commercial areas, from two multinational companies based in Minas Gerais were performed. The results indicate that the level of integration can be analyzed as a combination of three factors: 1) absence of overlapping of perceptions about integration factors over the processes, balance between formality and informality, and absence of manifest conflicts of interest. This is a setting that provides a deeper definition than those obtained in the studied literature, which basically present integration mechanisms, without detailing how these should be applied in order to generate higher levels of integration.
