Welcome back, IA aficionados! Now that we’ve covered the essentials of Information Architecture (IA) in Part 1, it’s time to level up. In Part 2, we’re diving into mapping and modeling—the art of creating a user-centered IA that guides people from Point A to Point “Yes, I found it!” with ease.
Whether you're a seasoned UX designer or new to IA, this part is about crafting a structure that feels natural and effortless for users. Let’s get into the mapping and modeling tools and techniques that turn your ideas into clear, user-friendly blueprints.
Definitions: Why Mapping & Modeling Matter
Imagine trying to navigate a new city without a map or GPS. That’s what it feels like for users navigating a poorly structured website or app. When we talk about mapping and modeling in IA, we’re talking about two crucial steps:
Mapping Creating visual representations of your IA—sitemaps, user flows, and hierarchies that show how content is organized and connected.
Modeling Organizing and categorizing content in a way that matches users' mental models and supports their goals.
The goal here? Build a structure that feels intuitive and helps users find what they need with minimal friction. Now, let’s break down the process.
Step 1: Crafting Your Sitemap – The IA Blueprint
Your sitemap is the “bird’s-eye view” of the digital landscape you’re creating. It shows the big picture of how all the content connects, from the main navigation to deeper sub-pages. But remember, not all sitemaps are created equal. Here’s how to create one that works.
Best Practices for Site Mapping
Start with Research Before jumping in, understand your user’s needs through user interviews, surveys, or analytics. Look for patterns in how they search for information and what goals they have when using your site or app.
Keep It Hierarchical (But Not Too Rigid) Your sitemap should clearly show the main categories and subcategories without turning into an endless maze. The classic “three-click rule” (users should find content within three clicks) still holds true, but it’s more about logical flow than an exact count.
Prioritize Key Content Place the most relevant information where it’s easy to find. Use your sitemap to guide users to high-priority content in as few steps as possible.
Tools for Site Mapping
Miro and Figjam These are excellent tools for collaborative sitemapping. With drag-and-drop features, you can quickly test different arrangements and see what feels most natural.
Lucidchart and Whimsical Both are intuitive options for creating structured, visually clear sitemaps. They let you test relationships between pages and visualize user flow.
Step 2: User Flow Diagrams – The Journey Maps
User flows are different from sitemaps; they’re all about mapping the user’s journey through specific tasks or goals within the site. Think of user flows as the path a visitor takes to get from one point to another—like booking a ticket, buying a product, or finding information.
Creating Effective User Flows
Identify User Goals What do users want to achieve? Define clear objectives like “finding pricing info,” “signing up,” or “contacting support.” Each user flow should be designed to meet a specific goal.
Limit Distractions User flow should be as frictionless as possible. Avoid dead ends or irrelevant options that can sidetrack users from their goals.
Test Multiple Paths Real-life users often take unexpected routes. Consider different entry points (homepage, search results, direct links) and ensure the flow works smoothly from each starting point.
Tools for User Flow Diagrams
Overflow Overflow is a great tool for user flows, especially if you’re looking for clickable, interactive prototypes. It integrates with Sketch, Figma, and Adobe XD, making it ideal for creating visual flows.
Figma and Figjam For more complex designs, these tools allow you to map user flows while building out the UI, ensuring a consistent journey from start to finish.
Step 3: Card Sorting – The Secret Weapon for Categorization
Card sorting is a technique for organizing information based on how real users think. Card sorting shows how people think about information. By asking users to group items that make sense together, it helps you build an IA that matches what users expect.
Types of Card Sorting
Open Card Sorting Users organize and label categories themselves. This is helpful in the early stages when you’re building your IA from scratch.
Closed Card Sorting Users sort items into pre-set categories. This works well when you have an existing structure and want to validate or refine it.
Tools for Card Sorting
OptimalSort This is a popular choice for digital card sorting. It provides detailed analytics on user groupings and labeling, which can inform your IA structure.
UXtweak A flexible tool that lets you conduct card sorting remotely and analyze results quickly. Great for remote teams and when you’re working with larger participant groups.
Step 4: Tree Testing – Validate Your IA
Tree testing is a method of validating your IA by stripping out the visuals and focusing on text-based navigation. This allows you to see if users can find information easily within your structure without being swayed by design elements.
How to Conduct a Tree Test
Choose Tasks Write scenarios for users, like “Find the return policy” or “Locate the troubleshooting guide.” Aim for tasks users would commonly complete on the site.
Analyze Success Rate Measure how quickly and accurately users complete tasks. If users consistently get lost or take too long, it’s a signal that your IA needs work.
Tools for Tree Testing
Treejack (Optimal Workshop) Treejack is the industry standard for tree testing, with easy-to-understand reports on where users get lost and which categories work best.
UsabilityHub While it’s more general, UsabilityHub has tree testing functionality that’s straightforward and quick for smaller projects.
Mapping & Modeling for IA Success
Mapping and modeling aren’t just technical tasks; they’re storytelling tools for creating a seamless, engaging user experience. Each flow, sitemap, and card sort brings you closer to an IA that truly speaks the user’s language.
Up Next
As we move into Part 3, we’ll get into advanced IA techniques and explore the art of faceted navigation and IA patterns that make even the largest content structures feel easy to navigate.
Until then, happy mapping—and may your sitemaps be clear, your user flows smooth, and your card sorting enlightening!
