# Information Architecture

## Overview

Information architecture (IA) is the backbone of findability and understanding. Good IA makes the product feel smaller and more coherent than it is.

## When to Use

- Designing or restructuring navigation
- Organizing complex feature sets or content libraries
- Improving search and labeling
- Scaling products without overwhelming users

## Core Practices

- Understand user mental models (card sorting, interviews)
- Define clear categorization and hierarchy
- Design navigation systems (global, local, contextual)
- Create consistent, user-centered labels
- Support wayfinding (where am I, what’s here, where can I go)
- Validate with tree testing or usability tests

## Principles

- Organize for users’ goals, not internal org charts
- Fewer top-level items often beats deep complexity
- Labels should use the user’s language
- IA should scale as the product grows
- Search and browse should complement each other

## Verification

- [ ] Users can predict where to find key items
- [ ] Labels are understood without explanation
- [ ] Navigation remains usable as content grows
