Affinity Diagram
Definition
An Affinity Diagram is a collaborative tool employed in user research and design thinking to sort and categorize ideas, observations, or data into meaningful groups. This technique enables teams to visualize connections among diverse pieces of information, facilitating a clearer understanding of user needs and behaviors.
Typically used in the early stages of the design process, Affinity Diagrams help teams synthesize large amounts of qualitative data—such as user feedback, brainstorming outputs, and findings from usability tests—into organized clusters. By doing so, they can identify trends and key themes that may not be immediately apparent.
The process of creating an Affinity Diagram is often collaborative, involving team members from various disciplines. Participants write down their observations or ideas on sticky notes and then work together to group these notes based on similarities. This promotes discussion and encourages a shared understanding of the data, ultimately leading to more informed design decisions.
Expanded Definition
The concept of Affinity Diagrams originated in the 1960s, developed by anthropologist Jiro Kawakita. It gained popularity as a tool for organizing complex information in various fields, including business and education. In UX design, the Affinity Diagram is particularly valuable for distilling insights from user interviews and surveys.
Affinity Diagrams not only help in organizing data but also foster team collaboration and creativity. By engaging different stakeholders in the synthesis process, teams can leverage diverse perspectives, leading to richer insights and more user-centered solutions.

Example
For instance, a UX team conducting research for an e-commerce website may gather user feedback through interviews. After collecting the insights, they use an Affinity Diagram to group comments related to site navigation, product discovery, and checkout experiences. This visual organization helps the team prioritize areas for improvement based on user pain points and desires, leading to informed design choices.
