Design is iterative, right? While creating part two of the two-part “characteristics” diagram (part one: The Essential Characteristics of User Experience), I realized that it was actually a three-part diagram and that what I had created first, was actually last! So now it reads:
- An introduction of “characteristics” and “principles”. (pdf | jpg)
- The characteristics. (pdf | jpg)
- The principles – formerly part one, “essential characteristics”. (pdf | jpg)
My thanks to Rob Weening, one of my colleagues at work, for helping me see this “re-frame”. His flash of inspiration was that the characteristics are the building blocks of an experience (the “what”) and principles are how an experience is put together (the “how”). The dodgy DNA analogy in the diagrams, however, is all my fault.
P.S. Dave reminded me with his comment that the ten characteristics are almost certainly not an exhaustive list, they’re just a start.




So Bank of America seem to have embraced the “User Experience” term. (thanks to Chuck Haeberle for finding this).
We have 17 sets of wooden window blinds in our house. They’re dust magnets and I hate cleaning them so I offer my latest invention to the world (i’m sure its been done before). Meet the Swiffinator.
