Statistical process control - Wikipedia

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).SPC can be applied to any process where the "conforming product" (product meeting specifications) output can be measured.
