Interpreting an Affinity Diagram

The end result of the affinity process is a collection of problems, grouped by main ideas. These main ideas, represented by the header cards, may provide key drivers that need to be addressed for achievement of the goal.

It is important to remember that the affinity diagram uses only subjective opinions of issues. As with any of these types of tools, we can use the tool to gain focus, but we must then must substantiate these ideas with objective evidence using properly analyzed data.

These issues may be further developed in other tools, such as a prioritization matrix.
