An Affinity Diagram, or affinity map, is a brainstorming technique where all ideas are listed out, then similar ideas are grouped together. After all the groups have been formed, each group is then titled and given subsets to further organize your thoughts. Creating an affinity diagram is an easy way to recognize patterns among what may seem like drastically different ideas. Creating a visual that allows us to see which ideas are similar to each other, lets us organize our thoughts, and allows for the most efficient decision-making processes.
