Managing, Controlling, and Improving Quality

DOUGLAS C. MONTGOMERY, PhD, is Regents Professor of Industrial Engineering and Statistics at Arizona State University. Dr. Montgomery is a Fellow of the American Statistical Association, the American Society for Quality, the Royal Statistical Society, and the Institute of Industrial Engineers and has more than thirty years of academic and consulting experience. He has devoted his research to engineering statistics, specifically the design and analysis of experiments, statistical methods for process monitoring and optimization, and the analysis of time-oriented data. Dr. Montgomery is the coauthor of Generalized Linear Models: With Applications in Engineering and the Sciences, Second Edition and Introduction to Time Series Analysis and Forecasting, both published by Wiley.

“Your book Managing, Controlling, and Improving Quality worked out very well in my senior-level class in the past fall semester. Actually students really liked the book. I planned to cover a little bit of acceptance sampling plans but I didn’t have sufficient time. I did cover Chapter 9 Reliability though. It was a great mix of managing aspects of quality, tools and techniques of quality control and design of experiments, plus a little bit of reliability. Students were happy and I was also happy. We will keep using this book which is ideal for my class.”—Dr. Byung Rae Choe, Indiana University of Pennsylvania
