Quality management 3
The document discusses seven basic quality tools: check sheets, stratification, histograms, Pareto charts, Ishikawa diagrams, scatter diagrams, and control charts. It provides examples and explanations of how to implement each tool, including how to classify data, indicate locations and frequencies, and analyze relationships between variables. Check sheets involve tallying traits, stratification organizes data into classifications, histograms and Pareto charts display distributions graphically, and scatter diagrams and control charts assess correlations. Ishikawa diagrams map potential causes for effects through a cause-and-effect tree structure.

- 5. Check sheet procedure •Classification: A trait such as a defect or failure mode must be classified into a category. • Location: The physical location of a trait is indicated on a picture of a part or item being evaluated. • Frequency: The presence or absence of a trait or combination of traits is indicated. Also number of occurrences of a trait on a part can be indicated. • Measurement Scale: A measurement scale is divided into intervals, and measurements are indicated by checking an appropriate interval.

- 22. PARETO chart A classificationorder / prioritizing order – Pareto charts are used to identify and prioritize problems to be solved. – They are actually histograms aided by the 80/20 rule adapted by Joseph Juran. •Remember the 80/20 rule states that approximately 80% of the problems are created by approximately 20% of the causes.
