Quality professionals have many names for these seven basic quality tools, first emphasized by Kaoru Ishikawa, an engineering professor at the University of Tokyo and the father of "quality circles".
Begin your journey of quality by mastering these tools, and you will have a name for them too: "indispensable".
1. Cause and effect diagram (also called Ishikawa or fishbone chart): Identifies many possible causes of an effect or problem and classifies ideas into useful categories.
2. Check sheet: A structured and prepared way to collect and analyze data; A generic tool that can be adapted for a wide variety of purposes.
3. Control Charts: Charts used to study how a process changes over time.
4. Histogram: The most commonly used graph to show frequency distributions, or the frequency with which each different value occurs in a data set.
5. Pareto diagram: Shows in a bar graph what are the most significant factors.
6. Scatter diagram: Graphs pairs of numerical data, a variable on each axis, to search for a relation.
7. Stratification: A technique that separates data collected from a variety of sources so that patterns can be viewed (some lists replace "stratification" with "flow chart" or "performance chart").
