Typical application

To search for potential product innovations.

To break down and classify large data sets.

To review and question ideas for problem resolution or process improvement.

Step-by-step procedure

STEP 1 The team facilitator describes the use of a dendrogram and asks the team to brainstorm items within an area of interest. See example Development of a Better Classroom Pointer.

STEP 2 The facilitator draws the dendrogram on a whiteboard as the participants further break down a selected characteristic or idea.

STEP 3 The participants discuss preferred ideas and select one for product innovation or problem analysis, as shown in this example.

STEP 4 The participants review the flowdown of characteristics or ideas and date the dendrogram.
