This study investigated the use of the statistical process control (SPC) as a tool in a manufacturing firm to improve quality and cost effectiveness. With emphasis on early detection and prevention of the problems, SPC was shown to have a distinct advantage over other quality methods such as inspection of final products. There was need to check gauges and machines, and determine need for some maintenance or overhaul work to be carried out as faulty machines could not produce expected quality products. There was need for operators to be trained, new documents to be produced and actions for the future to be agreed on. There was a need for reviewing the operations and monitoring key equipment for re-tooling or adjustment to achieve required levels of plant performance.
