Information architecture (IA) refers to the process of organising, structuring and labelling content, data as well as other information in a way that makes it easy to access and use. It is a foundational aspect of user experience (UX) design and involves creating a hierarchical structure for information to define relationships between different elements. IA shapes a navigation system that allows users to move through the content and find what they are looking for. IA can be applied to a wide range of contexts, such as websites, applications, databases and content management systems. Effective IA helps users find the information they need more easily, reduces cognitive overload and improves overall user satisfaction and engagement. IA is developed alongside user research, interaction design, and content strategy, and involves an iterative process of prototyping, testing and refinement.
