GMS 401 Lecture 8: Lecture 8
Document Summary
Outline: statistical process control (spc, process capability, acceptance sampling. A process used to monitor standards by taking measurements and corrective action as a product or service is being produced. A basketball player, for example, may have a good shooting percentage one night but a poor one the next night. We use control charts, however, to try to determine when the variation is so far beyond the norm that we think it is likely caused by something extraordinary. For example, the basketball player may have been sick on the day that she shot 10% from the floor, or she might have been eaten a granola bar before the game on the day that she shot 90%. If a sample of a production lot contains more than a specified number of defective items, statistical process control can give us a basis for rejecting the entire lot.
