Information Architecture

Information architecture defines how a product is organized. It maps pages, navigation, objects, labels, user paths, and content hierarchy so design does not become a collection of disconnected screens.

Overview

What this document is

Information architecture defines how a product is organized. It maps pages, navigation, objects, labels, user paths, and content hierarchy so design does not become a collection of disconnected screens.

IAUXNavigationPage mapProduct structureContent hierarchy

Fit signals

When to use it

  • The product has multiple roles, pages, workflows, or content types.
  • Users need to find, compare, create, review, or manage information.
  • The team is designing a dashboard, portal, admin system, or marketplace.
  • The PRD has features but not yet a clear product structure.

Audience and ownership

Who uses it

Founders, product designers, UX leads, and teams shaping complex products, portals, dashboards, or document-heavy systems.

Gather before writing

Inputs required

  • Object map
  • Page inventory
  • Navigation model
  • User-path checklist

What each part should cover

Section-by-section guide

Objects

Describe the objects clearly enough that a founder, teammate, or AI agent can use it without needing hidden context.

Navigation

Describe the navigation clearly enough that a founder, teammate, or AI agent can use it without needing hidden context.

Pages

Describe the pages clearly enough that a founder, teammate, or AI agent can use it without needing hidden context.

Roles

Name the people involved, what they need, and what they are responsible for approving or using.

Paths

Describe the paths clearly enough that a founder, teammate, or AI agent can use it without needing hidden context.

Patterns

Describe the patterns clearly enough that a founder, teammate, or AI agent can use it without needing hidden context.

Practical workflow

How to create and use it

  1. 01Extract product objects, roles, and workflows from the PRD.
  2. 02Group related pages, actions, and content into a navigation model.
  3. 03Map key user paths and edge cases.
  4. 04Hand off IA to wireframes, design system, and engineering routes.

Copy into your workspace

Starter template

  1. 01List product objects, roles, and user tasks.
  2. 02Create page inventory and navigation hierarchy.
  3. 03Map top user paths, search/filter behavior, and detail pages.
  4. 04Validate IA against PRD workflows and permissions.

Make the draft usable

Weak vs strong examples

Objective

Weak

Create a information architecture for the product.

Strong

Organize navigation, pages, content groups, object relationships, and user paths before interface design starts. Define the decisions it must unlock, the inputs required, and the handoff assets needed for the next team.

Handoff

Weak

Share the document with the team.

Strong

Share the approved information architecture with owners, open questions, acceptance checks, and the next document in the build chain.

How to know it is useful

Quality checklist

  1. 01A designer can start wireframes from the IA.
  2. 02Primary objects and page hierarchy are clear.
  3. 03Role-based navigation and permission differences are visible.
  4. 04Search, filters, details, and empty states are considered.

Before you hand it off

Document readiness checklist

  • The information architecture has a named owner and approval path.
  • The business or product decision this document supports is explicit.
  • Inputs, assumptions, and open questions are separated from confirmed facts.
  • Scope boundaries and non-goals are clear enough to prevent silent expansion.
  • The document can be handed to a teammate, agency, or AI agent without hidden context.
  • A designer can start wireframes from the IA.
  • Primary objects and page hierarchy are clear.
  • Role-based navigation and permission differences are visible.

Generate the first draft

AI prompt

Draft prompt

Create an information architecture document for this product. Include product objects, user roles, page inventory, navigation model, route structure, content hierarchy, key user paths, permissions, search/filter behavior, empty states, and wireframe handoff notes.

Avoid these

Common mistakes

  • Starting visual design without product structure.
  • Naming navigation around internal teams instead of user intent.
  • Missing detail pages, settings, and empty states.
  • No role-specific navigation model.

Use this after the draft

Handoff assets

  • Object model
  • Page inventory
  • Navigation hierarchy
  • Route and state checklist
