Kaoru Ishikawa’s quality philosophy can be summarized by his
11 points:

1. Quality begins and ends with education.
2. The first step in quality is to know the requirements of the customer.
3. The ideal state of quality control is when quality inspection is no
longer necessary.

5. Quality control is the responsibility of all workers and all divisions.
6. Do not confuse means with objectives.
7. Put quality first and set your sights on long-term objectives.

Joseph Moses Juran. Juran was born in 1904 in Romania. Since 1924,
Juran has pursued a varied career in management as an engineer,
executive, government administrator, university professor, labor arbi-
trator, corporate director, and consultant. Specializing in managing for
quality, he has authored hundreds of papers and 12 books, including
Juran’s Quality Control Handbook, Quality Planning and Analysis
(with F. M. Gryna), and Juran on Leadership for Quality. His major
contributions include the Juran trilogy, which are three managerial
processes that he identified for use in managing for quality: quality
planning, quality control, and quality improvement. Juran conceptual-
ized the Pareto principle in 1937. In 1954, the Union of Japanese
Scientists and Engineers (JUSE) and the Keidanren invited Juran to
Japan to deliver a series of lectures on quality that had profound influ-
ence on the Japanese quality revolution. Juran is recognized as the
person who added the “human dimension” to quality, expanding it into
the method now known as total quality management (TQM).
