The Seven Basic Tools of Quality is 7 simple quality tools than can be used by any professional for quality improvements. The concept behind the seven tools came from Ishikawa (famous quality professional from Japan) who stated 90% of all quality related issues can be solved only using these basic tools. In addition to that, then they are so simple that they, with exception of the control chart, can be taught to and used by almost any person.
For effective problem solving, it is essential to be able to identify a problem, use the appropriate tools based on the nature of the problem, and communicate a solution to others.
