IA, Information architecture. It’s in the middle of **CONTENT, CONTEXT, USERS**. It has 4 components:
1. **Organization**: Scheme + structure
2. **Labeling**: textual & iconic
3. **Navigation**: global + local + contextual + suplemental
4. **Search**: Know-item, exploratory, exhaustive, refinding.
It’s done for **2 primary human needs:**
