Evaluation de la méthode des personas en intervention corrective, préventive et prospective

Abstract : This thesis is part of the research on personas. As user models, personas restore in a personalized way, behaviors, attitudes or contexts of use. Thus, they are commonly used in the field of digital product design. We propose using them in a broader context i.e in interventions focused in occupational health and systems performance. In the literature on personas they are considered as a powerful tool for idea generation and idea selection. In addition, the research mainly in the domain of the psychology of creativity shows that personas are actually likely to improve creative performance. However, very few studies have focused on this aspect. The question is to establish whether the personas are able to generate new and relevant ideas. Five studies were carried out to answer this question. They indicate that personas do not generate more ideas than other sources of inspiration taken into consideration. Their fundamental contribution lies in the nature of the ideas generated and in their ability to orchestrate the selection of these ideas. Moreover, personas support the construction of common representations, the simulation activity and the discussion in the working groups. These results confirm the contribution of personas to a transformation or design process. They allow us to open up perspectives for an enrichment of the intervention
