The objective of this article is to contribute to the epistemological, theoretical, methodological, and pedagogical debates concerning the relationship between research activities, training activities, and work activities. Its main focus is on new forms of engineering, thought of as cooperative and transformative. After situating the issues of the reciprocal triadic relationships between the three poles, the article presents two practical cases of transformative cooperative engineering. The authors then return to their epistemological position, which is socio-constructivist, complex, interactionist, and critical. They sketch out the first elements of an elaborate system of intelligibility (multi-referential and transdisciplinary) aimed at supporting the hypothesis of an engineering process of joint transformation (trades, actors, organizations, training provision). The article also presents the research methodology (training-action-research) developed. A discussion of the issues and conditions of possibility of cooperative and transformative engineering concludes the article.
