Une démarche centrée utilisateur pour la conception d'un portail coopératif d'aide à l'innovation

This paper presents the approach that we adopted to design a cooperative environment to assist the technological innovation process in an extended firm. This approach involved two main steps. The first step consisted of obtaining a description of the requirements and a cognitive model of the collaborative work carried out by the members of the project. This was used to build a cooperation space made up of Collective Tasks that are performed using a finite number of Basic Cooperative Functions. The second step consisted of translating this cognitive model into UML use case scenarios such an approach ensured that the resulting portal was structured, not in a thematic or functional manner, but according to the cooperative situations that the project members actually encounter. MOTS-CLÉS : projet d’innovation, conception, coopération, plate-forme collaborative, modélisation cognitive, cas d’utilisation.
