An Affinity Chart (or Affinity Diagram) organizes a large amount of data according to their natural relationships.

Useful for bringing order out of chaos, Affinity Charts make complex processes & procedures easier to grasp by 1) breaking them down into their constituent parts and 2) reorganizing them into groups based on similarity. In practice, this involves writing ideas onto notecards or sticky notes, and then grouping these ideas into similar columns. This is generally a silent activity completed by 1 or 2 members of a group.
