Process

The affinity diagram organizes ideas with following steps: # Record each idea on cards or notes. # Look for ideas that seem to be related. # Sort cards into groups until all cards have been used. Once the cards have been sorted into groups the team may sort large clusters into subgroups for easier management and analysis. Once completed, the affinity diagram may be used to create a cause and effect diagram. In many cases, the best results tend to be achieved when the activity is completed by a cross-functional team, including key stakeholders. The process requires becoming deeply immersed in the data, which has benefits beyond the tangible deliverables.
