The document "Statistical Method from the Viewpoint of Quality Control" by Walter A. Shewhart, edited by W. Edwards Deming, is a foundational work in the field of statistical quality control. The book explores the three steps of quality control: specification, production, and inspection, and discusses the role of statistical methods in achieving uniformity in product quality. Shewhart emphasizes the importance of statistical control in both the physical and mathematical senses, defining a state of statistical control as a condition where the variability in product quality is minimized to an economic minimum. The book also delves into the historical development of quality control, from early stone tools to modern mass production, and highlights the shift from exact science to probability and statistical concepts in the 19th and 20th centuries. Shewhart introduces the concept of tolerance limits and the use of statistical techniques, such as the control chart, to achieve statistical control. The book is a comprehensive guide for understanding the principles and techniques of statistical quality control, emphasizing the practical application of statistical methods in improving product quality and economic efficiency.The document "Statistical Method from the Viewpoint of Quality Control" by Walter A.
