The CTQ tree diagram can map specific requirements to key drivers of quality and on to a specific measurement. Tree diagrams can help translate customer desires into product characteristics.

To Create a CTQ Tree Diagram

It's often easiest to start with Post-it Notes and a flipchart and then transcribe the results to the QI Macros CTQ Tree Diagram template.

  1. Develop a clear statement of the customer requirement (e.g., good service). Place it on the left side of a board, wall, or easel and work toward the right.
  2. Brainstorm all of the drivers necessary to deliver the requirement.
  3. Determine the critical to quality measures that can be used to monitor these requirements.
