Helps you structure websites and apps so users can actually find things. You'll use this when redesigning navigation, organizing large content libraries, or building taxonomies that match how people think rather than how your database works. The approach is methodical: card sorting to understand mental models, hierarchy design keeping it shallow (max 3 levels), wireframing navigation flows, then validation through tree testing. What stands out is the emphasis on research first, particularly the mental models piece, because most IA failures happen when teams organize content around their org chart instead of user needs. Includes practical guides on card sorting, sitemap structure, and search design.
