Document Summary

A process used to monitor standards, make measurements, and take corrective action as a product or service is being produced. Graphic presentations of process data over time, with predetermined control limits. Inspection: a means of ensuring that an operation is producing at the quality level expected. At your suppliers plant while they are producing. At your facility upon receipt of goods from your supplier. Natural variation: variability that affects every production process to some degree and is to be expected; also known as common cause. Assigned variation: variation in a production process that can be traced to specific causes: typical sources of assigned variation: Natural and assignable variations distinguish two tasks for the operations managers: The first is to ensure that the process is capable of operating under control with only natural variation. The second is to identify and eliminate assignable variations so that the process will remain under control.
