RÉSUMÉ Cet article a pour objectif de présenter une approche permettant d’explorer différents “ points de vue ” en conception, à partir de l’utilisation conjointe de l’Analyse cognitivo-discursive (ACD) et de l’analyse géométrique des données, afin de contribuer à outiller la conception. Une étude menée auprès de concepteurs ayant des fonctions différentes (ingénieurs, projeteurs) et travaillant dans le domaine de la sécurité a permis de formaliser quelques spécificités implicites associées à la notion de point de vue. Les résultats mettent également en évidence convergences et divergences de points de vue en relation avec la fonction occupée et ont permis de proposer quelques recommandations. La démarche d’analyse proposée est susceptible d’intéresser tout ergonome étudiant la conception ou tout autre domaine, puisque les méthodes présentées sont généralisables à toute recherche utilisant des entretiens.

EXPLORATORY VIEWPOINTS ANALYSIS : ITS CONTRIBUTION TO THE PROVISION OF TOOLS TO SUPPORT THE DESIGN PROCESS The aim of this paper is to present an approach to the exploration of different viewpoints in the design process. These viewpoints are studied through cognitive-discursive analysis and geometric-data analysis, and should provide information for the development of design tools. A study was undertaken with operators and those working in various functions in the safety field (e. g. designers, engineers). From this study, some implicit specificities from the viewpoint concept were formalized. The viewpoint concept can be associated with that of operative representation, classically used in cognitive ergonomics. The results show the role of each design actor in relation to his/her function. They are thus consistent with the use of the viewpoint concept, as presented in the majority of recently published research, which involves heterogeneity and a multitude of factors. These viewpoints would be enriched with work knowledge, such as experience feedback concerning accidents and incidents. Exploring the various viewpoints in design may provide a means to enabling the various actors to become conscious, and share their respective approaches and contributions in design. The details of analysis are presented, together with the theoretical bases which justify it. It is likely to interest any ergonomist studying design or any other field, since the methods presented can be generalized to include any research using verbalization, subject to the precautions presented.
