Statistical process control is a tool which enables both manufacturers and suppliers to achieve control of product quality by means of the application of statistical methods in the controlling process. This book gives the foundations of good quality management and process control, including an explanation of what quality is, and control of conformance and consistency during production. The text offers clear guidance and help to those unfamiliar with either quality control or statistical applications and covers all the necessary theory and techniques in a practical and non-mathematical manner. Featuring user-friendly presentation, it has been updated for the fifth edition to reflect developments in the field. It is designed for self or group instruction for both student and practicing engineers, scientists, technologists and managers.
