Statistical Process Control

Statistical Process Control

Statistical Process Control (SPC) is a quality control method used to monitor, control, and improve processes. It involves the application of statistical techniques to analyze and measure process variations. By understanding and controlling these variations, organizations can ensure consistent quality and improve their processes.

SPC uses statistical tools, such as control charts, to monitor process performance over time. Control charts help distinguish between common cause and special cause variations. Common cause variations are inherent in the process and expected, while special cause variations are unusual and need to be investigated and addressed.

Implementing SPC can provide various benefits, including reduced defects, improved product quality, increased customer satisfaction, and enhanced process efficiency. It allows organizations to identify and eliminate sources of variations, leading to more stable and predictable processes.
