In information architecture, which activity helps determine intuitive content organization by grouping related items?

• A. card sorting
• B. wireframing
• C. survey analysis
• D. usability testing

Answer: (A)

Grouping related items to match how users think about your content is what card sorting helps you discover. In this activity, participants sort items into piles that make sense to them and label those groups. This reveals natural boundaries and the terms users expect, which directly informs how you structure information—how you organize sections, create navigation, and name categories. You can have participants create their own categories (open sort) or use predefined ones (closed sort), and then analyze the groupings to see which items belong together and what labels best describe each cluster. From this, you build intuitive organization that aligns with users’ mental models.

Other activities focus on different aspects: wireframing demos the layout and flow on screens, survey analysis concentrates on collecting and interpreting responses, and usability testing checks how easily users can complete tasks. While valuable, they don’t specifically reveal how to group content in a way that feels natural to users.
