1. Information architecture involves structuring information environments like websites and intranets through organization, labeling, search, and navigation to support usability and findability. It is an emerging discipline focused on applying design and architecture principles to the digital landscape. 2. A cross-channel strategy is needed to address fragmentation across sites, domains, and identities. This ensures coherence across platforms, devices, media while balancing consistency and optimization. 3. Ubiquitous information architecture (IA) considers intertwined physical and digital experiences across diverse channels using sensors and mobile technologies. It frames IA beyond websites to include ambient, ubiquitous experiences.
