GMS 401 Chapter Notes - Chapter 10: Statistical Process Control, Statistic, Acceptance Sampling
Document Summary
Statistical quality control: use of statistical techniques and sampling in monitoring and testing quality of goods and services. The part of statistical quality control that relies primarily on inspection/ test of previously produced items is referred to as acceptance sampling. Statistical quality control is important because it provide 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, for each characteristic. Plan how inspection is done, what to expect, and whether centralized or on site. The amount of inspection can range from no inspection whatsoever to inspection of each item. The cost of inspection and resulting interruptions of a process typically outweigh the benefits of. Items that have large cost associated with passing defective products require inspection.
