Information architecture

Organise information and choices so people can understand where they are and what they can do.

What the field is

Information architecture shapes structures, labels, relationships, navigation, and findability. It connects a user’s mental model with the product’s content and capabilities without simply mirroring the organisation that built it.

Methods

Ways to practise the skill.

Choose methods because they reduce the uncertainty in front of the team—not because a template says they belong in the process.

01

Content inventory

Catalogue content, ownership, quality, duplication, audience, and lifecycle.

Helpful whenA product has grown unevenly or teams disagree about what exists.
02

Card sorting

Ask participants to group and label items to reveal mental models and vocabulary.

Helpful whenDeveloping or challenging a taxonomy.
03

Tree testing

Test whether people can find items in a text-only hierarchy without visual-design cues.

Helpful whenValidating navigation structure before interface polish.
04

Object modelling

Define core objects, attributes, relationships, actions, and states.

Helpful whenDesigning complex products whose structure must work across many screens.
