Document Summary
Quality control activity that evaluate quality characteristics relative to a standard, and takes corrective action when they do not meet standard. Accomplished by monitoring and inspecting the product during process. 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 is the appraisal of goods/services against standards. Statistical process control planning process: define important quality characteristic, and how to measure, for each characteristic, determine a quality control point, plan. Iii. how to inspect how much to inspect where centralized or on-site: plan the corrective action process. Before a costly operation, before an irreversible process, before a covering process. Statistical process control: statistical evaluation of the output of a process during production. Random variation: natural variations in the output of process, created by countless minor factors.
