Information Architecture (IA)
Information Architecture is the practice of deciding how to arrange the parts of something to be understandable and easy to diggest. For websites and apps, it means organizing content so users can easily find what they are looking for.
The Blueprint of UX
Before drawing wireframes, you must structure the data. If a website is a house, IA is the floor plan. If the kitchen is inside the bathroom, no amount of beautiful interior design will fix the fact that the house is fundamentally broken. Even if the bathroom or toilet is closer to the kitchen, sanization and common sense will tell you that it is a wrong approach. The same happens with UX. People expect related terms in the same categories but a good idea is to use one of the following techniques to understand the users' expectations.
Key IA Methodologies
- Card Sorting: Give users a stack of cards with topics written on them and ask them to organize the cards into groups that make sense to them. This reveals the user's mental model, ensuring your navigation categories match their expectations.
- Tree Testing: The reverse of card sorting. Give users a text-only version of your proposed navigation hierarchy and ask them to find a specific item. This proves whether your categories actually work in practice.
- Sitemaps: A visual diagram showing the hierarchical relationship between different pages of a website.
