Complete Guide To Information Architecture In UX Design

If you’re designing a SaaS product, a website or even an app and you’re working with UX designers, you may have heard the term “information architecture” (IA) quite a bit – and you may not be sure what it means, or how it relates to UX design.

In this guide, we’ll be taking an in-depth look at information architecture, and how it relates to UX design. You’ll learn everything you need to know in order to understand the concept of information architecture in detail, and how it relates to UX design. Let’s get started.

Defining Information Architecture – What Is It?

When it comes to incorporating any kind of information, the human brain needs one thing – structure. Imagine trying to read a dictionary that wasn’t in alphabetical order, a novel which does not have its chapters arranged in the correct sequence, or a textbook without a table of contents, glossary, or bibliography.

In the same way, we need a consistent structure that we can use when we’re browsing information online. That’s information architecture – the art and science of designing navigational systems and constructing content in such a way that it’s intuitive to browse and understand on websites, web and mobile apps, software, and more.

To boil it down further, information architecture is the practice of figuring out how you can arrange the parts of something to make it understandable. The goal is to organize content in such a way that users can quickly adjust to how the product works, and find everything that they need without making a big effort.

The structure of the content and the method by which this is achieved is different, depending on the application or website. A SaaS product, for example, has different needs than an eCommerce site, because the purpose of each is distinct.

Understanding The Role Of Information Architecture In Design

In any effective development project, information architecture helps define the “skeleton” of a project. UX Designers typically focus on IA first, before determining a design approach and developing further any design elements.

This is because design elements – from visual elements and graphics to interactions, functionality and navigation – must be built on strong information architecture. Even the best content and design will fail without using appropriate IA. UX is important, but even if an app or a website looks great, users will quickly become frustrated if it becomes clear that the information is not organized properly, and it’s confusing to use.

IA And UX Design – How Do They Relate?

If you know a bit about UX design, you may be wondering if there is really a difference between IA and UX at all. After all, they’re both concerned with intuitive user experience, simple navigation, and other such things, right?

It’s true that these two terms do relate to one another, but they are not the same. You can think of IA as a blueprint for a home – while UX design is more like the finished house.

In other words, IA is a basic design structure of information – one which can be turned into wireframes and sitemaps. It’s a high-level hierarchy that is used to organize, catalog, and understand the placement of content in any product. When building a new website, SaaS product or an app, UX designers use IA as a way to construct an outline of how the site will work, so that they can plan out a navigation system.

UX, on the other hand, is concerned with much more than simply structuring content. Using IA principles in UX is important, of course. But there are many other things that UX designers must focus on, too – like influencing user’s behavior, making it pleasant to interact with the product, designing intuitive navigational systems, and much more.

So, you can think of IA as the foundation or blueprint of UX. Both IA and UX are essential for a great product, because without strong IA, your content will be difficult to navigate – but without proper UX, it will not be fun to navigate. Both practices build upon one another, and both are used by most UX designers who specialize in user-focused design.

Understanding IA System Components And What They Are

If you’d like to dive more deeply and understand a bit more about IA, it’s a good idea to have a basic knowledge about each individual component of information architecture.

The information architecture components – organization systems, labeling systems, navigation systems, and searching systems – are defined in Information Architecture for the World Wide Web, one of the pioneering texts in this field. Below are more in-depth meaning of each component.

Organization Systems

Organization systems are, as the name implies, a way to categorize how information is divided. They are designed to help users predict where they will be able to find a certain type of information. There are three main types of organization systems.

  • Hierarchical – Using a visual hierarchy helps users determine the importance of each individual element. By using things like contrasting fonts, element sizes, and colors, users can quickly understand the important information on a page at a glance.
  • Sequential – This type of organization system creates a path for a user. Imagine checking out on Amazon or another online retailer. You know what to expect – click your shopping cart, view your order summary, check out, choose your shipping address, enter your payment method, and then confirm your order and place it. That’s an example of a sequential organization system.
  • Matrix – Matrix organization systems allow users to browse content based on different kinds of groupings or “schemes.” By doing things like allowing users to sort information by alphabetical order, date, topic, and other categories, users can quickly find what they’re looking for.

Almost every website, SaaS product and app uses a combination of all of these information architecture systems to provide a seamless, intuitive user experience.

Labelling Systems

Labelling systems are a way to simplify data representation and group multiple sets of data and content into just a few words, allowing for easier navigation.

If your website has a “Contact” page, for example, this is an example of a labelling system. Rather than having a different page for your email address, phone numbers, physical address and other information, it’s grouped and labelled into the same page – one that users intuitively know will contain this information. Your user understands that they’ll find that information on the “Contact” page.

Navigation Systems

Navigation systems include a wide variety of different design techniques and actions that must be taken in order to guide a user through the process of using an app or a website – allowing them to interact with it successfully, and achieve their goals.

There are many different types, including embedded navigation, global navigation, local navigation, contextual navigation, supplemental navigation and more.

Searching Systems

Searching systems allow users to enter search terms into a search bar – just like they would in a search engine like Google – and find the results that they are looking for quickly. This is a great choice for websites and apps with a huge amount of data and different features.

Imagine trying to use an enormous website like without a search bar, and you’ll understand why searching systems are so important in some websites and applications.

Final Thoughts

We hope you’ve learned a bit more about IA and UX, and how these two fields of design are distinct – yet related and codependent. During the UX design process, IA play a pivotal role in helping mapping out the flow of the user and making sure that all the functionalities, screens are covered before starting with the design. This not only helps the designers but also helps stakeholders and devs understand how the product will flow.
