Statistical Process Control

Statistical process control (SPC) is a statistical tool for monitoring and controlling a process. SPC monitors the variation in a process with the aim to produce the product at its best target values. SPC uses process charts consisting of data plots, upper control limit (UCL), lower control limit (LCL), and the mean for the process. The variation is the result of both common and special/assignable causes. Common causes produce normal variation in an established process. Special/assignable causes are abnormal causes of variation in the process. There are four steps in SPC:

1. Measure the process. Ensure data collection is thorough, complete, and accurate.

2. Bring the process under statistical control. Eliminate special/assignable causes.

3. Monitor the process. Keep the process under statistical control.

4. Improve the process toward best target value.
