The Web, Information Architecture, and Interaction DesignJonathan Korman of Cooper Designs writes about the differences in interaction design (IxD) and information architecture (IA):
"IA calls for exercises like card sorts, usability testing for category labels, hierarchical structure diagramming, and so forth. IxD calls for exercises like workflow analysis, usage scenarios, wireframed walkthroughs, and so on. The work done, and the skills needed to do it, differ considerably between the two. Just as few people can fully master the skills of both graphic design and IA, few people will master the skills of both IA and IxD. It serves both organizations and practitioners for people to specialize."
