Quality Improvement Through Planned Experimentation

This edition in the quality field covers sequential experimentation, providing step-by-step guidelines on how to build the sequence and how to use simple graphical methods to determine how much planned changes are contributing to variation in needed data.

This breakthrough resource provides the methodology that engineers need to plan and conduct experiments to understand cause-and-effect mechanisms in complex systems and test whether changes to products, processes, and systems are improvements. It offers a comprehensive model that reveals the tools and properties of sound experiments, the methods of planned experiments, and their application to the design of new and improved products and services. Including case studies of experiments in action and forms and checklists for designing planned experiments, the Second Edition includes new and expanded coverage of how to test changes ... evaluate the measurement process ... extend planned experiments to large systems ... and apply experiments to new product design. Featuring a new organization that underscore its unified approach to experiment design, this new edition enables firms to effect changes in products and services that are, verifiably, improvements.
