Effective Quality Control in Management of Processes | IVT

KEY POINTS DISCUSSED

• The purpose of quality control evaluation is to determine, with a high statistical confidence, whether or not the process mean or variability have changed
• All processes should be designed to produce a desired target value
• The choice of equipment, materials, methods, and training defines the predictable range of process variability
• Process variability is cumulative
• Quality controls must be simple and easily understood
• Quality control data are used by the front line to make real time decisions
• Quality control data have limited predictive power
• Quality control points must be placed at logical process check points to facilitate a “go” or “no-go” decision by an operator.
