Validating the Quality Function Deployment Analysis

A lot of effort on the part of the project team often goes into building the QFD house of quality matrices; more effort is required to maintain the matrices as more information becomes available. Some project teams build only the first matrix linking customer and project requirements, while others go on to build a second matrix to link project requirements with either key methods, processes, or specifications.

It is imperative that the project efforts toward QFD be relevant and effective. In part, achieving a useful result requires validation of the QFD results by business managers (Phase A) and by other subject matter experts (SMEs) on the various phases. Validation begins with coordination with the business analysis documented on the balanced scorecard, Kano analysis, or other competitive, marketing, or risk analysis. Validation often follows the so-

called "V-curve" common in system engineering. An illustration of the "V-curve" applied to the QFD validation is shown in Figure 8-13.

Once validated to external drivers, such as the balanced scorecard or Kano analysis, the project team can validate the QFD matrices by examining the internal content. For instance, there should be no blank rows or columns. At least one data element should be associated with every row or column. Attributes that are scored strongly in one area should have strong impacts elsewhere and, of course, document all the assumptions and constraints that bear on attribute ratings and relationships. Examine the assumptions and constraints for consistency and reasonableness as applied across the project. Independent SMEs could be employed for the process, and the independent SMEs could be employed in a Delphi-like strategy to make sure that nothing is left behind or not considered.
