BU385 Chapter Notes - Chapter 10: Statistical Process Control, Acceptance Sampling, Central Limit Theorem
Document Summary
Best companies emphasize designing quality into process (continuous improvement and six sigma quality projects); reduces need for inspection. Statistical quality control use statistical techniques and sampling in monitoring and testing of quality. Statistical process controls- part of statistical quality control occurs during production. From least progressive to most progressive: acceptance sampling (inspection before and after production) -> statistical process control (corrective action during production) -> continuous improvement and six sigma (quality built into the process) Phases of statistical quality control/ improvement in a company: acceptance sampling (inputs) -> statistical process control (transformation) -> acceptance sampling (outputs) Provides economical way to evaluate quality of products and meet expectations. Inspection appraisal of a good/ service against a standard. Only characteristics that can be measured can be controlled; must consider how to measure. Must be a standard used to evaluate measurement.
