Affinity Clustering
What is Affinity Clustering in User Research?
Affinity Clustering is a user research technique that involves grouping similar ideas, insights, or data points into clusters based on their relationships or common themes. This method helps researchers organize and analyze large amounts of qualitative data to identify patterns and prioritize user needs.
Synonyms: Affinity Diagramming, KJ Method, Affinity Mapping, Thematic Analysis

How Affinity Clustering Works in User Research
Affinity Clustering is a collaborative process that typically involves the following steps:
- Gather data: Collect user insights, observations, or feedback from various research methods.
- Write ideas: Transfer each piece of information onto individual sticky notes or digital cards.
- Group similar items: Arrange the notes into clusters based on common themes or relationships.
- Create categories: Label each cluster with a descriptive category name.
- Analyze patterns: Examine the clusters to identify overarching themes and priorities.
Benefits of Affinity Clustering in User Research
Affinity Clustering offers several advantages for user researchers:
- Organizes large amounts of qualitative data efficiently
- Encourages collaboration and consensus among team members
- Reveals hidden patterns and insights that may not be immediately obvious
- Helps prioritize user needs and pain points
- Provides a visual representation of research findings
Examples of Affinity Clustering in User Research
- Website Redesign: Clustering user feedback about navigation issues to identify common pain points.
- Product Development: Grouping feature requests to determine priority areas for improvement.
- Customer Support: Categorizing support tickets to identify recurring issues and potential solutions.
Frequently Asked Questions
-
What's the difference between Affinity Clustering and Affinity Diagramming? Affinity Clustering and Affinity Diagramming are essentially the same technique. The term "clustering" emphasizes the grouping process, while "diagramming" focuses on the visual representation of the results.
-
How many people should participate in an Affinity Clustering session? Ideally, 3-8 people should participate to ensure diverse perspectives while maintaining efficiency.
-
Can Affinity Clustering be done remotely? Yes, there are digital tools and online whiteboards that allow teams to conduct Affinity Clustering sessions remotely.
-
How long does an Affinity Clustering session typically take? The duration can vary depending on the amount of data, but sessions usually last between 1-3 hours.
