Typical Uses

Quality managers, project managers, marketing professionals, and anyone who uses brainstorming to generate ideas can use an affinity diagram to distill a large number of ideas to a refined set of related categories. Affinity diagrams are also known as the Kawakita Jiro or KJ method.

Best Practices

  • Identify the purpose. Begin by deciding what issue or aspect of your business you wish to focus on with your diagram. Place it at the top of the page.
  • Determine groupings. Decide on a logical set of related categories.
  • Determine contributing factors. Make a list of ideas and issues generated by the brainstorm.
  • Organize. Place each factor or idea beneath a category. Try combining duplicate issues to simplify.
  • Analyze and share. Step back and look at the diagram. Analyze with various other coworkers or team members and it should be able to help you make a decision or see things more clearly.

The main difference is that Affinity Diagram focus on ideas whereas KJ Analysis is focusing on facts.
