Design of experiments in quality engineering

Based on Jeffrey Luftig’s highly successful training course for quality engineers and managers, this book now offers you the fundamentals of experimental design and thorough guidance on the steps required to carry out experiments that can help your firm improve quality, reduce costs, and increase customer satisfaction. Case studies illustrate every aspect of experimental procedure, including how to define the research question...identify key variables ... select the appropriate model...understand measurement systems...ensure internal and external validity...select the appropriate sampling plan...execute and monitor the experiment...and correctly analyze, report, and standardize the results. Included are pointers on how to avoid financial disasters arising from poorly constructed and performed experiments, as well as a detailed checklist to help optimize the efficiency of even the most complex experiment.
