Resumen: Eco-innovation initiatives include eco-ideation processes for proposing ideas that are innovative and represent an environmental improvement. The evaluation of the results of eco-ideation has been focused on evaluating these two aspects, but it is necessary to know how related factors, such as the thinking profile of group members, influence the generation of concepts during the creative process. This study proposes a metric that analyses the results of the creative process within conceptualization from three approaches: innovation, circularity and group activity. The group activity approach is related to the influence of the leader in the management of a creative group. The proposed metric allows us to observe the creative process, the interactions among the participants, the design decisions made, and the evaluation of the creative product which will determine which type of creative groups obtain better results. The application of the results and the proposed metric allow the creation of groups oriented to objectives, for both specific or permanent workgroups. This can be used for the initial selection of participants for eco-ideation groups, or to improve the group functionality during intermediate stages.
