Usability of a potential design

Three-quarters of the way through a Five Sketches™ session, to help iterate and reduce the number of possible design solutions, the team turns to analysis. This includes a usability analysis.


After Œ informing and defining the problem  without judgement  and  generating and sketching lots of ideas  without judgment , it’s often a relief for the team to start Ž  analysing and judging  the potential solutions by taking into account the project’s business goals, development goals, and usability goals).

But what are the usability goals? How can a team quickly assess whether potential designs meet those usability goals? One easy answer is to provide the team with an project-appropriate checklist.

Make your own checklist. You can make your own or find one on the Internet. To make your own, start with a textbook that you’ve found helpful and inspiring. For me, that’s About Face by Alan Cooper. To this, I add things that my experience tells me will help the team—my “favourites” or my pet peeves. In this last category I might consult the Ribbon section of the Vista UX Guide, the User Interface section of the  iPhone human-interface guidelines, and so on.
