The structure itself must do the navigational work. Information architecture is the design of that structure: what exists, what it is called, and how it relates to everything else. Good IA is invisible. Users find what they need without thinking about the structure. Bad IA forces users to hold a map in their head. --- ## Naming is Design The names given to entities, sections, and actions are one of the most consequential design decisions in a large application.
