Abstract: To clarify the concept and structure of a Six Sigma project, the authors present the first part of a hypothetical Six Sigma project at the Green Belt level. The focus of this section of the case study is on the Define and Measure phases in the define-measure-analyze-improve-control (DMAIC) method for process improvement. The study details preparing a business case with a project charter, the suppliers-inputs-process-outputs-customers (SIPOC) analysis, and Voice of the Customer analysis, and the measurement phase involving critical-to-quality (CTQ) variables, Gauge R&R studies, and developing CTQ baselines.

Gitlow, H., Berkins, A., and He E., “Safety Sampling: A Case Study,”
Quality Engineering, vol. 14, number 3, year 2002, pp. 51-65.]

Abstract: Safety sampling is a management tool for making the workplace safer by studying how processes and people operate. By identifying unsafe behaviors future accidents can be avoided. Rochester Electro-Medical, Inc., a medical-products manufacturer, began a safety-sampling program to improve the work environment and to reduce insurance premiums. Safety-sampling plans were designed to meet the specific needs of the company. Pareto analysis of collected data enabled management to develop a plan to identify and eliminate unsafe behaviors.

This perspective has generated extremely positive student reactions for a decade.

Gitlow, H., "Innovation on Demand," Quality Engineering,
vol. 11, no. 1, 1998-1999, pp. 79-89.

Abstract: This article explains how managers can create innovations on demand. Currently, innovations are derived from inspirations or as spin-offs of new technology. Unfortunately, both of these sources are not controllable by management; they happen through serendipity. What managers need is a method to create innovations on demand. This article compares two models for the management of innovation which appear only in the Quality Management literature: one developed by Kano and the other developed by Shiba. Also, the article presents a new model for innovation which is an extension of the Kano and Shiba models, It incorporates the strengths and avoids the weaknesses of both models. Finally, the article presents a detailed case study of the extended model.
