Information Architecture
/ˌɪn.fɚˈmeɪ.ʃən ˈɑːɹ.kɪˌtɛk.tʃɚ/ · Noun · Development · Origin: 1976
Definitions
The structural design of shared information environments — the art and science of organizing, labeling, and structuring content on a website or app so users can find what they need and understand where they are.
In plain English: How content is organized and labeled on a website or app. Good information architecture means you can find what you're looking for without thinking too hard, like how a well-organized library puts related books near each other.
Example: "Our information architecture is a mess — the settings page has 47 options in a single flat list with no grouping or search."
