This book is an introductory book on improving the quality of a process or a system, primarily through the technique of statistical process control (SPC). There are numerous technical manuals available for SPC, but this book differs in two ways: (1) the basic tools of SPC are introduced in a no-nonsense, simple, non-math manner, and (2) the methods can be learned and practiced in an uncomplicated fashion using free software (eZ SPC 2.0), which is available to all readers online as a downloadable product. The book explains QC7 Tools, control charts, and statistical analysis including basic design of experiments. Theoretical explanations of the analytical methods are avoided; instead, results are interpreted through the use of the software.
From the Back CoverA complete guide to the essential statistical process control techniques for understanding data and problem solvingOrganizations across various areas of industry strive to improve the quality of their products, employees, and services, utilizing the technique of statistical process control (SPC) to measure variables in order to determine where improvements need to be made. Basic Statistical Tools for Improving Quality provides an introduction to improving the quality of a process or a system, primarily through SPC, while also showing how to implement continuous improvement into process control. The book analyzes quality management problems through cohesive explanations, real-world applications from different industries, and interpretations of results using software.
Promoting a 'learn by example' approach, the authors introduce the basic tools of data analysis, control charts, and process improvement in a comprehensive style that does not rely heavily on mathematics. The book utilizes the author's own user-friendly eZ SPC software to carry out key practices such as making tests and confidence intervals and using graphical statistics to communicate ideas. Basic control charts for means, variances, and proportions are featured along with advanced control charts and guidance on:
Generating a control chart to evaluate and monitor a process
Detecting the first moment when a process breaks down or goes out of control
Creating process improvement by investigating potential factors that affect the process and/or process output
Implementing correlation analysis, regression, analysis of variance, and factorial design using eZ SPC
Real-world examples illustrate the discussed methods, and every chapter contains a set of exercises. All presented data sets are available on the book's related website along with the eZ SPC software, which readers can freely download to create their own results and analyses. Basic Statistical Tools for Improving Quality is an excellent reference for applied statisticians and practitioners working in the fields of engineering, business, and management science. It also serves as a supplemental book for courses on quality control at the upper-undergraduate and graduate levels.
