Network IA connects content through links and relationships rather than hierarchies. Users jump between related items freely—like Wikipedia where every page links to related pages. No central structure; content is organized by associations. Powerful for knowledge bases, wikis, and interconnected content.
Use network IA for wikis, knowledge bases, documentation with heavy cross-referencing, or when content has many-to-many relationships. Works best when combined with strong search and breadcrumbs (since users can enter from anywhere). Essential for Roam/Obsidian-style bidirectional linking. Avoid for linear processes or when users need guided navigation.
