Process control charts tutorial

Learn how to apply process control charts to identify special-cause variation and improve processes.

To illustrate the concepts, we will use data on the copper concentration in a plating process. Copper concentration in a plating pool is controlled by an automated colorimeter that takes readings and adjusts the concentration as required. To verify the correct functioning of a new colorimeter system, copper concentration is measured manually six times per shift. Six operators regularly perform the shifts.

In this tutorial you will perform the following tasks:
