5 Questions
Who is considered the Father of Japanese Quality and what are some of his contributions to quality tools and techniques?
Dr. Kaoru Ishikawa is considered the Father of Japanese Quality. He advocated the use of 7 quality tools, invented the Fishbone diagram (4M/5M or cause and effect diagram), and sponsored the concept of Company Wide Quality Control (CWQC).
What is the purpose of a Histogram in the context of quality tools and techniques?
The purpose of a Histogram is to arrange and analyze collected data. It represents the variation or dispersion and averages, commonly using a bar graph to show the frequency distribution of data/values.
What is another name for the Cause and Effect analysis tool, and how does it help in problem-solving?
Another name for the Cause and Effect analysis tool is the Fishbone or Ishikawa diagram (aka 4M/5M or cause and effect diagram). It helps in finding the root causes or factors of any problem.
What is the function of a Checksheet in relation to collecting data for quality analysis?
The function of a Checksheet is to collect quantitative or qualitative data for analysis in quality improvement processes.
What is the Pareto Diagram and how is it used in quality improvement?
The Pareto Diagram is a bar chart used to separate the 'vital few' from the 'trivial many' factors. It helps in prioritizing and focusing on the most significant causes of a problem for improvement.
