This up-to-date survey of statistical quality control reviews basic probability and statistics, basic control chart principles (including cumulative sum procedures and multivariate charts), and provides insight into statistically designed experiments and related topics. It also reviews the use of statistics in quality control in the US and Japan, with a critical examination of Taguchi methods. The approach is conceptual rather than mathematical, making this book accessible to a wide audience. The text has been designed for statisticians, engineers, production and operations managers.
