A method for sorting and making sense of data. Data points can be recorded on sticky notes (the UX practitioner's Swiss army knife) and sorted into logical groups. Could be employed as an individual or group exercise.
Participants can experiment with different arrangements to see which makes the most sense. Affinity Diagramming helps to expose crucial relationships and patterns in data that may not be initially apparent.
We liked this affinity diagram tutorial from Mind Tools.
Beyer & Holtzblatt's book Contextual Design also talks about affinity diagrams.
