SPC Process Control

All improvement requires change, but not all change results in improvement. The key to identifying beneficial change is measurement. Statistical Process Control (SPC process control) is an industry standard methodology for measuring and controlling quality during the manufacturing process. Attribute data (measurements) is gathered from yields as they are being produced. By setting lower and upper control limits, discrepancy in the process can be found before they appear in deformed product, entirely eliminating the need for final inspection.

Statistical Process Control is the application of simple statistical methods to measure and control this variability during manufacture. SPC process control performed during the manufacturing/assembly process not only obliterates the need for final inspection, but equally essential significantly minimizes and quantity of material scrap along with direct and indirect labor waste. The result is a direct increase in bottomline profitability. SPC process control and its primary tool—the control chart—give practitioners and researchers with a technique of better understanding and communicating data from any improvement efforts.
