# Information Architecture

> The structure of a product's content and functionality — how things are grouped, labeled, and connected so people can find them.

Information architecture is the structure underneath a product: how content and functionality are grouped, what each group is called, and how people move between them. It decides whether somebody can find a feature that exists, which is a different question from whether the feature is any good.

It sits before layout in the order of decisions. A [wireframe](https://www.themasterly.com/glossary/wireframing) arranges what a screen contains; information architecture decides what belongs on that screen in the first place, and which screen a person should be on. A [sitemap](https://www.themasterly.com/glossary/sitemap) is the usual way of drawing the result.

## The four things it decides

**Grouping.** What belongs together. Every grouping makes a claim about relationships, and users read the claim whether or not it was intended.

**Labelling.** What each thing is called. This is where most findability problems live, and it is the cheapest thing to fix and the hardest to notice, because everyone internal has already learned the vocabulary.

**Hierarchy.** What is top level and what is nested. Depth is invisibility: anything three levels down is found only by people who already know it exists.

**Relationships.** How things connect across the hierarchy. A strict tree forces one home for everything, and real products contain items that legitimately belong in two places.

## Your model is not their model

The structure a company builds tends to mirror the company. Teams own areas, areas become sections, and the product's organisation quietly encodes an org chart that no user can see.

Users arrive with a model built from their own work. In B2B software that is usually something like: things about my organisation, things about my team, things about this piece of work, things about me. Structure that matches this needs no teaching. Structure that matches yours needs a help article, and the existence of a help article explaining where something lives is a reliable signal that the architecture failed.

The other frequent mismatch is between lifecycle and category. Companies organise by object type; people organise by what they are doing. Somebody preparing a monthly close does not think of it as visiting reports, then settings, then exports.

## Testing it cheaply

Information architecture is unusually testable, and the two standard methods need no design work at all.

**Card sorting** hands participants your labels and asks them to group them, and optionally to name the groups. Open sorting, where they invent the names, surfaces the vocabulary they actually use. Run it with ten to fifteen people and the patterns are visible.

**Tree testing** is the inverse: give somebody a bare, unstyled structure and a task, and see whether they can get to the right place. It isolates structure from every other kind of help, which is exactly what you want to know, and it can be run on a structure that does not exist yet.

Both work before anything is designed, which makes them among the cheapest research a team can run, and both are routinely skipped in favour of arguing about menus.

## Information architecture in B2B products

Three complications arrive that consumer sites rarely face.

**Permissions fragment the structure.** An admin, a member and a viewer each see a different product. Designing the admin's view and letting the others fall out of it produces a structure most users never experience as coherent.

**Multi-tenancy adds a layer nobody expects.** Organisation, workspace, project, item. Every additional level of nesting is a decision users have to understand before they can find anything, and products accumulate these levels one acquisition at a time.

**Settings become a dumping ground.** Anything with no obvious home lands in settings, and after two years settings contains billing, integrations, permissions, notification preferences, data retention and a feature somebody could not place. A settings area that needs its own search is a structural failure that has been deferred.

## Changing it on a live product

Restructuring a product people already use carries a cost that a new product does not: existing users have learned the old arrangement, and any improvement is also a disruption.

**Move things for a reason you can state.** "Billing moved under account because customers looked for invoices where they look for their plan" is a sentence that survives the complaints. "It felt tidier" does not.

**Keep the old routes alive.** Bookmarks, help articles, shared links and support macros all point at the previous structure. Redirects cost little and prevent a wave of tickets from people who did nothing wrong.

**Move in one deliberate step, not five quiet ones.** A single announced change is learnable. A structure that drifts every sprint means nobody ever finishes learning it.

**Watch search terms afterwards.** A spike in searches for something that used to be in the navigation is the clearest possible evidence that the move made it harder to find, and it arrives within days.

## In practice

Customers report that a product is hard to learn, and the team plans a navigation redesign.

Card sorting with twelve users returns a consistent grouping that differs from the product's in one specific way. Users put anything involving money in one place: invoices, plan, seats, usage limits. The product splits these between billing, account and admin, because three teams built them.

Tree testing confirms the consequence. Given the task of finding out why their bill increased, most participants look in billing, find only invoices, and stop.

The fix is a regrouping and three renamed labels. No new screens, no visual redesign, and the original brief would have redrawn the menu without changing what was inside it.

## Where teams get it wrong

- **Redesigning navigation instead of structure.** New menus over the old organisation move the problem.
- **Internal vocabulary as labels.** Feature names that made sense to the team who shipped them.
- **Deep nesting for tidiness.** Symmetry costs findability, and frequently used things belong near the top even when that looks unbalanced.
- **Letting settings absorb the leftovers.** Every item with no home makes the next one harder to find.
- **Never testing.** Card sorting and tree testing are cheap, need no design, and settle arguments that otherwise run for months.

## FAQ

**What is information architecture in simple terms?**

How a product organises what it contains: what is grouped with what, what each thing is called, and how somebody moves between them. If a user cannot find a feature that exists, that is an information architecture problem rather than a visual one.

**What is the difference between information architecture and navigation?**

Information architecture is the structure; navigation is one way of exposing it. Menus, search, breadcrumbs and in-product links are all views onto the same underlying organisation. Redesigning a menu on top of a structure that does not make sense moves the problem without solving it.

**How do you test information architecture?**

Two cheap methods. Card sorting asks people to group and name your content, which reveals the model they already hold. Tree testing gives them a task and a bare structure with no visual design, which shows whether they can find things when nothing else is helping them.

**What makes labels good?**

Using the words your users use, not the words your company uses. Internal names for features are the most common source of unfindable functionality, because the label makes sense to everyone who built it and to nobody who did not.

**Does information architecture matter in a product with search?**

Yes, because search rescues people who know what a thing is called. New users, and anyone exploring what the product can do, are relying entirely on the structure. Search is a shortcut for the informed, not a substitute for organisation.
