Chapter 3: Quality Control and Improvement Charts

Introduction

Quality improvement charts have a variety of uses.  In this library the charts are organized into three broad groups:  Shewhart control charts, other control charts and process improvement charts.  The Shewhart control charts were originally described by the statistician Dr. Walter A. Shewhart (1931).  Since this early work, other charts have been developed for engineering and management analysis of pro­cesses.  In the 1980s customized charts were developed for other retrospective analysis of quality management data.
