Abstract
This research focused on studying the statistical process control tool in manufacturing systems with the broad aim of upgrading them to improve on quality and cost effectiveness. It represents an attempt to address the deficiency in the literature of SPC implementation. With emphasis on early detection and prevention of the problems, SPC was shown to have a distinct advantage over quality methods such as inspection of end product. 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 quality good products. There was need for operators to be trained, new documents to be produced and actions for the future to be agreed on. A system of reviewing the progress and monitor the result was to be effected with as much priority as that given to financial results.
