  11. 11. Role of Edwards Deming • Deming is the final, and arguably most important, variable in the equation that led to Japan‟s economic revolution after the Second World War. • As Deming himself said, “Quick returns, whether by acquisition, or by divestiture, or by paper profits or by creative accounting, are self-defeating” (Deming 1985). When Japan adopted Deming‟s techniques, Japanese firms were not thinking about profit margins or stock prices. For them, it was about the success of Japanese industry, and the future of Japan as a nation.
