What is information architecture?

Information architecture (IA) is the art and practice of organizing and structuring information to create meaning and understanding. It helps people navigate complex information environments and find what they need to take action. When information is well-organized on websites, in apps, or even in buildings, it becomes easily accessible, understandable, and actionable for everyone who uses it.

As information continues to grow and change in our world, so does our understanding of information architecture.
