Statistical quality control- uses statistical techniques & sampling to monitor & test the quality of goods & services: acceptance sampling determines to accept or reject a product, statistical process control determines if process is operating within acceptable limits. Inspection- appraisal of goods/services against standards: how much/ how often, where/when, centralized vs. on-site. Statistical process control planning process: define the quality characteristics important to customers, and how each is measured. More favorable test environment: plan the corrective plan, uncovering the cause and correcting it. Statistical process control (spc)- statistical evaluation of the product in the production process: the quality control steps, type of variations, control charts, designing control charts, control charts for attributes, using control charts. If you find no points outside control limits, assume there is no assignable cause the process is stable and control. Sample mean control chart- the control chart for sample mean, used to monitor the process mean.
