affinity diagram
a simple technique for organizing concepts: designers write down ideas on a set of cards and then organize the cards by grouping them and by placing closely related concepts close to each other (e.g. by shuffling the cards on a table or pinning them to a wall); especially useful for uncovering the structure and relationships in a poorly understood domain. Affinity diagrams are often a good next step after a brainstorming sessions. Related “card sorting” techniques are useful for uncovering similar groupings from users.
