The Disciplines of User Experience Design

Dan Saffer updated the UX model from his book, Designing for Interaction.

I agree with the conclusion that User Experience Design is not a discipline on it's own but more "management and coordination between the disciplines to ensure holistic products".

In support of this conclusion, Liz Bacon pointed to a similar blog post: User Experience Design Does Not Exist.

The designers that work on amazon.com don't create the experience— they're responsible for building the system, product and service that allowed those different experiences to happen. The designers work to understand how the user interacts with the website to create the most desirable and profitable experiences. We call that interaction design.

Designers need to stop thinking that they're creating experiences. They're allowing them to unfold with sound design decisions.
