Waterfall

One of the main attributes of the design work we at ADGi do (and when I say design I mean interaction design and information architecture, not so much visual design) is that all of it is evidence-based. That is, all of it, and I really mean all of it, every interaction, every node in the site map, is driven out of user research and expert analysis.

Around the time Alan Cooper was giving his really great talk An Insurgency of Quality at this year’s IxDA, I was giving a talk that came to some of the same conclusions from a different starting point.
