In my morning malaise on the subway this morning I thought this:
Some of the best interaction designers I've worked with are like good
chess players. They are the kind of people who can think 39 actions
ahead, for each of the 27 different possible use scenarios. And they
are able to do this in their head.
As designers we try to focus on designing for the most important
stuff, and leaving feature creep on the roadside.
But when it comes down to actually making a design work, I believe
that the ability to imagine the 387 contingent possibilities is
critical to making the difference between an excellent and merely good
(Don't challenge me to a game of chess, I'm absolutely miserable at it)
