Information architecture (IA) shapes how information is organised and accessed in websites, software, and other shared digital environments. Thoughtful IA helps people find what they need and understand where they are. This lesson introduces the field, its different uses, its history, and its guiding principles.
Information architecture is the structural design of shared information environments. It involves arranging and labeling information so that people can use it effectively and locate it without unnecessary effort. The field applies ideas from design, architecture, and information science to digital spaces.
