Quality pros have many names for these seven basic tools of quality, first emphasized by Kaoru Ishikawa, a professor of engineering at Tokyo University and the father of “quality circles.”
Start your quality journey by mastering these tools, and you'll have a name for them too: "indispensable
Kaoru Ishikawa developed seven basic visual tools of quality so that the average person could analyze and interpret data.
These tools have been used worldwide by companies, managers of all levels and employees.
Kaoru Ishikawa Known for “Democratizing Statistics”
The Basic Seven Tools made statistical analysis less complicated.
Good Visual Aids make statistical and quality control more comprehendible. What are Quality control tools?
Seven qc tools are the fundamental instruments to improve the quality of product. They are use to analyse the production process, identify the major problems, control fluctuations of product quality, and provide solutions to avoid future defects. Statistical literacy is necessary to effectively use the qc tools. These tools use statistical techniques and knowledge to accumulate the data and analyse them.
THESE TOOLS ARE RELATED TO Numerical DATA processing

Quality control tools:
Cause and Effect Diagrams
Flow Charts
Checksheets
Histograms
Pareto Charts
Control Charts
Scatter Diagrams
What is cause and effect diagram:
A cause and effect diagram is “a fish-bone diagram that presents a systematic representation of the relationship between the effect (result) and affecting factors (causes).”
It was originally created and used by Dr. Kaoru Ishikawa and is sometimes called an Ishikawa Diagram. Also, because of its shape it is called a Fishbone Diagram. In general what you do is brainstorm ideas (causes) then group them in to categories. Those categories become the many branches of the Cause and Effect diagram.
