Defining Information Architecture

We define information architecture as:

1. The structural design of shared information environments.

2. The art and science of organizing and labeling web sites, intranets, online communities and software to support usability and findability.

3. An emerging community of practice focused on bringing principles of design and architecture to the digital landscape.

Are these definitions definitive? Absolutely not. Our craft is new and still taking shape. We’re clear on the center but fuzzy at the boundaries. This inherent ambiguity challenges us to think deeply and seek diverse perspectives.
