What is a closed card sort?
With a closed card sort, participants sort a list of items into predefined categories. They cannot update category names or add additional categories.
When should you conduct a closed card sort?
Testing an existing navigation structure: are my current category names understandable? Are there categories that aren't used by the users?
Leverage a closed card sort when adding new items into the existing structure to see how people fit new cards into existing categories.
You can also used closed card sorting to verify the labels that participants created during open card sorting.
