Pinning down a definition for information architecture (IA) was a common discussion in the readings. Resmini and Rosati (2011) explore the history of IA and its evolution from information design, to system design, to what we know as IA today. They explain that IA (the information science approach) is concerned with creating labels, organization, navigation, and connections with information in order to improve findability, usability, and overall user experience. This approach is not only concerned with design or with creating resources within a business environment, but takes a holistic approach to dealing with information which includes the goals of the user and the organization within their unique environments.
I like how Morville and Rosenfeld (2007) explain the broad reach of IA with the information ecology approach. They explain that users, content, and context all interact and constantly change. Not only is the subject of IA pervasive, the discipline was developed to take on new, emerging problems (Resmini & Rosati, 2011). Morville and Rosenfeld (2007) explain that the field deals with the ambiguous and requires intuition and creativity. I think trying to understand IA in this changing environment is part of the process and what keeps IA on the cutting edge.
