Statistical Process Control

Statistical Process Control (SPC) is a method using statistical techniques to monitor and control a process to ensure it operates at its full potential and produces conforming products. It helps identify and address variations in production.

TECHNICAL DEFINITION

Statistical Process Control (SPC) is a quality control methodology that employs statistical methods, such as control charts, to monitor and analyze process variation over time, distinguishing between common cause and special cause variation to maintain process stability and capability.

BACKGROUND

Statistical process control (SPC) or statistical quality control (SQC) is the application of statistical methods to monitor and control the quality of a production process. This helps to ensure that the process operates efficiently, producing more specification-conforming products with less waste scrap. SPC can be applied to any process where the "conforming product" output can be measured. Key tools used in SPC include run charts, control charts, a focus on continuous improvement, and the design of experiments. An example of a process where SPC is applied is manufacturing lines.
