No, that's not what I had in mind at all... the project's usability team can do a heuristic evaluation at any time, without any input from end-users. A heuristic evaluation obviously requires knowledge of the heuristics in the first place, which end-users don't normally have, or at least wouldn't consciously use to describe the problems they were having. Heuristic evaluations are certainly a useful tool for spotting potential problems with a design, but by no means guaranteed to spot "actual" problems. Expert walkthroughs are a little better for spotting actual problems, as they're based on scenario-driven usage. But again, the real users aren't involved, and the "experts" doing the walkthrough don't usually have comparable domain knowledge. You're absolutely right that users usually don't know how to fix the problem, and I wasn't advocating asking them to do so[1]. But on the GNOME project at least, with which I'm most familiar, just gathering all those problems together from many different sources so we can decide what to do about them is one of the biggest headaches. I'd want any "feedback squad" to gather those problem reports together, and possibly help prioritise them. Then leave it to the usability team (in conjunction with the users, in the course of the usual user- centred design process) to come up with the solutions. Cheeri, Calum. [1] Although it's always good to ask anyway, because sometimes it'll spark a good solution, even if it ends up being considerably different from theirs. But a lot of the time, as you say, their suggestions are way off the mark. -- CALUM BENSON, Usability Engineer Sun Microsystems Ireland mailto:[EMAIL PROTECTED] Java Desktop System Team http://blogs.sun.com/calum +353 1 819 9771 Any opinions are personal and not necessarily those of Sun Microsystems _______________________________________________ Desktop_architects mailing list Desktop_architects@lists.osdl.org https://lists.osdl.org/mailman/listinfo/desktop_architects
