'''Statistical process control''' ('''SPC''') is a method of [[quality control]] which employs [[statistics|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. Key tools used in SPC include [[run chart]]s, [[control chart]]s, a focus on [[Continuous Improvement Process|continuous improvement]], and [[Design of experiments|the design of experiments]]. An example of a process where SPC is applied is manufacturing lines.
