We also discussed design integrity, simplicity, abstraction, and discount usability testing. Now, we’ll talk about personas. It seems to me that personas are a bit like Critical Incident […]

In the second, we discussed Tognazzini’s Paradox: how the hardest part of designing an effective program is often what seems the most trivial—sometimes simply a matter of changing a single […]
