Dan Saffer, experience design director of Adaptive Path, shared on Adaptive Path’s blog this interesting presentation about how to make good design decisions. According to him it’s all about good guessing:

About a year and a half ago, when I first started thinking about the material that would eventually become UX Intensive: Interaction Design, I wondered what it was that helped designers make those leaps of faith, the great guesses, that we have to make on projects. So I came up with this talk, How to Make Good Design Decisions.
