SPC — statistical process control

Abstract

Statistical process control (SPC) is a technique for error prevention rather than error detection. SPC products will be of the required quality because they are manufactured properly rather than because they are inspected. Thus, it increases productivity by reducing scrap and rework and provides continuous process improvement. Other methods — such as flexible manufacturing systems (FMS), computer integrated manufacturing (CIM) and just-in-time (JIT) — which have aimed at increasing productivity, concentrate on hardware flexibility, integration of information flow or reduction of inventory. Seldom does a system use technology flexibility to produce the correct product.
