What is Statistical Process Control

Statistical Process Control (SPC) is a statistical procedure using control charts to see if any part of a production process is not functioning properly and could cause poor quality. SPC is used to inspect and measure the production process to see if it is varying from what it is supposed to do. If a sample point is outside the limits, the process may be out of control, and the cause is sought so the problem can be corrected. If the sample is within the control limits, the process continues without interference but with continued monitoring./p>
