The disciplinary separation resulting from the advancement of science and knowledge has generated biases regarding contact, understanding and action in the complexity and levels of reality. Transdisciplinarity, when calling for an examination of the real problems of the world, requires a methodological elaboration of dialogue. The epistemological level of the general methodology is not enough to direct actions of transformation, it requires the elaboration of methodologies that take into account the epistemological assumptions, the specific contexts and put actors and knowledge involved to dialogue. VETAS® Method systematizes a transdisciplinary dialogic methodology, operates as a method focused on identity, and allows applications in complex health situations, organizations and education.
