"...what is user experience design by itself, those areas that aren’t filled up with other bubbles? I tried to answer some of that in an earlier post, but the short answer is: not much, aside from coordination between the various disciplines, or what used to be called creative direction. It’s about the joining of the different disciplines, and not particularly a discipline in and of itself... Without the “raw materials” of the disciplines that make up UX, UX would be empty indeed." Some nice thoughts, clearly delineated, from Dan.
