L'orientation du cahier des charges constitue-t-elle une aide à la conception de sites web ergonomiques ? Vers la conception de sites web ergonomiques

This study aims at determining the effect of the orientation of the constraint conditions as a support for making web sites easier to use. Toward this end, we suggested to professional and novice web site designers to make a web site sketch according to an user constraint condition only with ergonomic constraints (UCC), or a mixed constraint condition with the same number of ergonomic and client constraints (MCC). Study results showed that the UCC helped designers, since professionals and novices took into account an important number of user constraints without hindering the consideration of client constraints. It was not the case for designers dealing with the MCC. Although these results are encouraging, designers introduced again an important number of usability problems in their web sites. The paper concludes with a presentation of studies conducted with professional and novice designers and ways to help them make web sites easier to use.
