Statistical process control (SPC) is a method used to monitor and control a process through the use of statistical techniques. It helps organizations ensure that their processes operate efficiently, producing more consistent and predictable results. By analyzing data collected from the process, SPC can identify variations that may indicate potential problems. SPC typically involves the use of control charts, which graphically display process data over time. These charts help determine whether a process is in a state of control or if corrective actions are needed. By applying SPC, businesses can improve quality, reduce waste, and enhance overall productivity.
