What an IA isn’t

As I work with IA more on my projects I realize that in the past I had thought IA and usability were very related. In many ways they are, but you are looking at two different areas. After reading Information Architecture is not Usability I now realize how they relate and differ:

The distinction between information architecture and usability may seem like semantics, but there are significant differences between the two disciplines. Though they are often discussed interchangeably, and practitioners are often well-versed in both, information architecture and usability differ in their scope and areas of focus.

The article really focuses on Peter Morville’s thought of “information architecture is a subset of usability, and usability is a subset of information architecture”, which really helped me understand what an IA does and doesn’t do.
