The study of the relationships that individuals maintain with each other has always been at the centre of the concerns of the most diverse areas of knowledge. Due to the plurality and multiplicity of approaches adopted as legitimate references for the production of knowledge about group processes, this study is a theoretical review centred on a specific model called: Operative Groups. Every operative group presupposes learning and learning, from the perspective of operative groups, is synonymous with change. In this way, it can be concluded that the study of a model for working in groups centred on principles of change is particularly appropriate in the face of the challenges and demands of the many different groups to which we belong today.
