  1. CM4120Chemical Plant Operations LabIntroduction to Quality Manufacturing How is Quality defined? ISO9000: The totality of features and characteristics of a product or service that bear on its ability to satisfy stated or implied need.

  2. CM4120Chemical Plant Operations LabIntroduction to Quality Manufacturing What is Quality Management? Managing systems and processes for the elimination of errors. Creating an environment for continuous improvement.

  3. CM4120Chemical Plant Operations LabIntroduction to Quality Manufacturing Formula for a generic process: A+B=C where A=system contribution B=human contribution C=desired (measurable) output Deming’s 14 Principles -- Handout

  4. CM4120Chemical Plant Operations LabIntroduction to Quality Manufacturing What is a Process? A logical sequence of tasks that repeatedly transform inputs into outputs. • Inputs may be people, information, or material. • Outputs may be products, services, or behaviors.

  5. CM4120Chemical Plant Operations LabIntroduction to Quality Manufacturing What is a System? Group of people and/or processes that are united with a common purpose. • Have identifiable characteristics. • Have measurable performance (quality) indicators.

  6. CM4120Chemical Plant Operations LabIntroduction to Quality Manufacturing What is Variation? Measurable change in the system output(s). Inherent to all processes or systems. • Common cause – built into the system. • Special cause – assignable to an event. • Tampering – result from tampering. • Structural – regular, systematic changes.

  7. CM4120Chemical Plant Operations LabIntroduction to Quality Manufacturing What is Statistical Process Control? Application of statistical methods to separate common cause variation from other causes. Uses control charting to convert fluctuations in a measured characteristic into useful information. A tool commonly used in quality systems.

  8. CM4120Chemical Plant Operations LabIntroduction to Quality Manufacturing Additional tools: Fishbone (Cause and Effect) Diagrams Viscosity variation

  9. CM4120Chemical Plant Operations LabIntroduction to Quality Manufacturing Additional tools: Pareto Charts A bar graph showing frequency of problem occurrence. Optionally, can have a “cumulative frequency” line and show percentage of total on bar graph. Used to display the relative importance or frequency of problems or conditions
