The creation and application of processes and resources realized by Engineering show important results in the exploitation of natural resources and in industry. Essentially, Engineering has been developed to satisfy the requirements of social agents but not to intervene in society itself. Artifacts produced by Engineering are used by society, but the elaboration of artifacts for managing directly society’s own processes is not considered, in general, as an issue of Engineering. We introduce concepts of Supra Disciplinary Engineering aiming at Total Engineering and its central expression in Engineering for Society. It searches to offer methods of classical Engineering to intervene, together with those of social and human sciences, in own processes of society and human beings, considering empirical evidence, objective information, reasoning and the respect of fundamental rights of society, in a responsible relationship with the natural world.
