Ishikawa Kaoru, the father of QCC and the master of Japanese quality management, was born in Japan and graduated from the Engineering Department of the University of Tokyo, majoring in applied chemistry. Ishikawa was the most famous exponent of Japan's "quality circle" movement in the early 1960s. He believes that the implementation of Japanese quality management is a revolution in business thinking, and its content is summarized into six items: 1. Quality first, 2. Consumer-oriented, 3. The next process is the customer, 4. Use data and facts to speak, 5. , Management that respects people, 6. Functional management.

In his teachings, Ishikawa emphasizes effective data collection and presentation. He is known for promoting quality tools such as Pareto charts and cause-and-effect (Ishikawa or fishbone) diagrams for optimizing quality improvements. Ishikawa Kaoru believes that cause-and-effect diagrams, like other tools, are tools to help people or quality management groups perform quality improvement. For this reason, he argued that open group discussions were as important as charting. The Ishikawa chart is useful as a systematic tool for finding, selecting, and recording the causes of quality variations in production, and for ordering their interrelationships.

Wise words: Standards are not the final source of decision-making, customer satisfaction is.
