Short answer
The four pillars are: 1) Organization Systems; 2) Labeling Systems; 3) Navigation Systems; and 4) Search Systems.
Explanation
The Organization System determines how content is structured and divided (hierarchically, chronologically, alphabetically, or by topic). The Labeling System chooses terms and language users understand instead of internal company jargon. The Navigation System defines how users move, identify their current location, and find previous or next paths. The Search System helps users query, filter, and access content directly without lengthy browsing.
Common mistakes
- Designing screens and colors before agreeing on the app's content structure and taxonomy.
- Using internal labels familiar to developers or management but unclear to end users.
