Closed Card Sort
What is a Closed Card Sort?
A closed card sort is a user research technique where participants organize predefined items into fixed categories, helping researchers understand how users group and categorize information within a specific structure.
Synonyms: Fixed category card sort, Structured card sorting, Predefined category sorting
How Closed Card Sorting Works
In a closed card sort, researchers provide participants with a set of predefined items (usually written on cards) and a fixed set of categories. Participants then sort these items into the given categories based on their understanding and preferences. This method is particularly useful when you have a clear idea of your information architecture but want to validate or refine it.
Benefits of Closed Card Sorting
- Validates Existing Structures: Helps confirm if your current categorization aligns with user expectations.
- Quantifiable Results: Easier to analyze and compare results across multiple participants.
- Time-Efficient: Generally quicker to conduct than open card sorts.
- Focused Feedback: Provides specific insights on predetermined categories.
When to Use Closed Card Sorting
Closed card sorting is most effective in the following scenarios:
- Refining an existing website or app structure
- Testing the intuitiveness of your current navigation system
- Comparing different organizational schemes
- Validating category labels and content groupings
