Which individual became a national folk hero in Japan for his work on management obligations and diseases?

The individual who became a national folk hero in Japan for his impact on management practices and quality control is W. Edwards Deming. His work in the post-World War II era profoundly influenced Japanese manufacturing and management, particularly through his philosophy on quality improvement and statistical process control.

Deming's approach emphasized the importance of understanding variation in processes and involved empowering workers to contribute to quality improvements. He taught that quality and productivity could be improved through a systematic approach to management and leadership, involving a commitment to continuous improvement and data-driven decision-making. His 14 Points for Management provided a framework for organizations to adopt these principles effectively.

His influence was so significant that he is credited with helping Japan rebuild its economy and gain recognition for high-quality products in the global market. This legacy made him a national folk hero in Japan, as he is often associated with the remarkable transformation of Japanese industries in the latter half of the 20th century.
