What is statistical quality control Wikipedia?

From Wikipedia, the free encyclopedia. Statistical process control (SPC) is a method of quality control which employs statistical methods to monitor and control a process. This helps to ensure that the process operates efficiently, producing more specification-conforming products with less waste (rework or scrap).

How is SQC used to control quality?

Statistical process control uses sampling and statistical methods to monitor the quality of an ongoing process such as a production operation. For example, the centre line of an x̄-chart corresponds to the mean of the process when the process is in control and producing output of acceptable quality.
