The group elicitation method for participatory design and usability testing

This short paper presents the Group Elicitation Method (GEM), a brainwriting technique augmented by a decision support system for participatory design and usability testing. GEM has been successfully used in four industrial projects to elicit knowledge from users, management and designers. In particular, in three of them it was used to elicit end-users' knowledge for the design of new user interfaces. This short paper discusses the properties of such a method and the lessons learned.
