Process Control

Abstract

Once the initial investigation of a process is complete (specifications and capability analysis), control charts can be constructed and evaluated to guide the continuous production of acceptable quality products. From the company’s viewpoint, this is the quality control manager’s most visible and useful function. When progressing from capability analysis to production quality control, use of single-sample measurements of variables are generally superseded by subgroups so that control charts for averages and ranges may be constructed. Procedures for establishing and maintaining these charts are described in Chapter 3. Our concern here is the interpretation of these charts.
