Abstract:

The Six Sigma and Design for Six Sigma methodologies often use experiments to improve product or service quality. However in many situations, there are several challenges associated with planning and designing experiments. Specifically for service industries, the qualitative nature of the parameters involved in quality improvement often causes project teams to struggle with how to design effective experiments that are manageable in both size and cost. To address this issue, we propose the development of a new Six Sigma design/improvement methodology in which the quality function deployment process is used to narrow the scope of experimental factors. The purpose of this method is to provide a systematic method for choosing between potentially important factors, in order to facilitate the design, execution, and analysis of experiments in service sectors. To illustrate the proposed approach, we provide a numerical example concerning a quality improvement project for a banking operation.
