What Is Statistical Process Control?
Simply put, SPC uses statistical methods and sampling programs to help plant and operations managers understand and control variability in their manufacturing processes. Process variations are displayed in real-time charts and trigger alerts as processes begin to trend out of expected, standard limits. The main objective of statistical process control (SPC) is to better manage operations and reduce waste and the need for rework. Plant and Ops managers like SPC because it gives them the concrete information they need to stop a line and fix problems before they spin out of control.
