I like this article, I have sometimes an ambivalent feeling towards design research, since it can be hard to digest sometimes. So this is my favourite quote:

“But I do agree with Don’s basic point that gaining a deep understanding of user needs does not in and of itself necessarily lead to a reframing of a technology or a business problem. This touches on something that we have been talking about a lot at frog recently – the pendulum has swung so much toward doing user research that we (as a profession) risk losing the magic that comes from conceptual thinking.”
