Ordinary users, precursory users and experts in the anticipation of future needs: Evaluation of their contribution in the elaboration of new needs in energy for housing
Abstract
With the growing emergence of ergonomic intervention aiming at designing future artefacts, needs analysis is extending to the anticipation of future needs. Both precursory users and experts are known for their deep knowledge of the studied field. In this study, we conducted 36 needs anticipation interviews with ordinary users, precursory users and experts, in order to determine the contribution of each profile to the identification of future needs. The lexical and manual analysis of the interviews shows that the precursory users' speech is the most valuable in terms of both richness and novelty. The discourse of the experts is also richer and more original than that of the ordinary users and differs from that of the precursory users: professional-based for the experts and experiencebased for the precursory users. We therefore recommend the inclusion of both experts and precursory users in the need's analysis and anticipation phase.
