Document Summary
The best companies emphasize designing quality into the process (ex. Undertaking continuous improvement and six sigma quality projects), thereby greatly reducing the need for inspections/tests. Statistical quality control: use of statistical techniques and sampling in monitoring and testing of quality of goods and services. It provides an economical way to evaluate the quality of products and meet the expectations of the customers. Inspection: appraisal of a good or service against a standard. Effective statistical process control requires the following planning steps: define the quality characteristics important to customers, and how each is measured. To be defined in sufficient detail not just for ex. The paint but the gloss of the paint or resistance of the paint: for each characteristic, determine a quality control point. Such as at the beginning or end of the process: plan how inspection is to be done, how much to inspect, and whether it is to be centralized on-site, plan the corrective action.
