Is it ever a bad thing to have too many ideas? Probably not, but if you've ever experienced information overload or struggled to know where to begin with a wealth of data you've been given, you may have wondered how you can use all of these ideas effectively.
When there's lots of "stuff" coming at you, it is hard to sort through everything and organize the information in a way that makes sense and helps you make decisions. Whether you're brainstorming ideas, trying to solve a problem or analyzing a situation, when you are dealing with lots of information from a variety of sources, you can end up spending a huge amount of time trying to assimilate all the little bits and pieces. Rather than letting the disjointed information get the better of you, you can use an affinity diagram to help you organize it.
Also called the KJ method, after its developer Kawakita Jiro (a Japanese anthropologist) an affinity diagram helps to synthesize large amounts of data by finding relationships between ideas. The information is then gradually structured from the bottom up into meaningful groups. From there you can clearly "see" what you have, and then begin your analysis or come to a decision.

Affinity diagrams can be used to:
Because many decision-making exercises begin with brainstorming, this is one of the most common applications of affinity diagrams. After a brainstorming session there are usually pages of ideas. These won't have been censored or edited in any way, many of them will be very similar, and many will also be closely related to others in a variety of ways. What an affinity diagram does is start to group the ideas into themes.
From the chaos of the randomly generated ideas comes an insight into the common threads that link groups of them together. From there the solution or best idea often emerges quite naturally. This is why affinity diagrams are so powerful and why the Japanese Union of Scientists and Engineers consider them one of the "seven management tools."
Affinity diagrams are not the domain of brainstorming alone though. They can be used in any situation where:
Here is a step-by-step guide to using affinity diagrams along with a simple example to show how the process works.

Generate ideas by brainstorming.
Write each idea on a separate sticky note and put these on
a wall or flip chart. Remember to:

Sort ideas into natural themes by asking:


Affinity diagrams are great tools for assimilating and understanding large amounts of information. When you work through the process of creating relationships and working backward from detailed information to broad themes, you get an insight you would not otherwise find. The next time you are confronting a large amount of information or number of ideas and you feel overwhelmed at first glance, use the affinity diagram approach to discover all the hidden linkages. When you cannot see the forest for the trees, an affinity diagram may be exactly what you need to get back in focus.
