What is an Affinity Diagram?
An affinity diagram is a tool often used to organize data and ideas. Affinity diagrams help you organize information into groups of similar items to then analyze qualitative data or observations.
Business and design teams have used affinity diagrams for a long time to organize ideas, complex information and even customer feedback into themes or groups. For UX researchers, affinity diagrams are often used for analyzing and synthesizing user research findings by patterns and themes. In this case affinity diagrams are sometimes referred to as the KJ method or an affinity map. Also in other broad application like business brainstorming or idea generation it may be called a cluster map.
