Currently we see a recurring invocation to the intersectorality as centerpiece of new social policies. The intersectorality even appears as the new promise about management issues to undertake social transformation goals. But usually there is so little questioning about it and is used with senses so general that it loses depth in its understanding, diluting the concern about how it is built and especially the real value it can bring to social outcomes. In this work we try to better define the specificity of intersectoral action and we intend to contribute to the construction of an analytical framework that, in addition to facilitating the understanding of the specificities of the joint action between different government sectors, can be used to clarify its results when there is a purpose to comprehensively undertake a social problem. Our intention is to approach to the intersectorality as variable caused, in addition to causing, and examine some of the factors that affect its practical realization and their intensities.
