Six Sigma and Motorola
Motorola was the forerunner in the development and application of six sigma quality practices. Shigeo Shingo would always rip SPC charts off the walls of plant manager's offices. It is not that Shingo was against SPC in the 1980's, but he was concerned it was overrated and undermined the true focus of the best quality practices inherent in source inspection.
As you can see Motorola and their six sigma fame has done little to propel the stock price higher. As Shingo once said, "source inspection" is the key to success. If you would like to know more about source inspection, please email me or call. Information is located on the bottom of this page.
Motorola stock performance has simply matched that of the S&P500 Index since 1990. No better and no worse, as of January 31, 2002. Former Shingo client companies, even in the depressed markets of Japan in the 1990's have performed at a much higher level and Six Sigma quality is not their core practice. (E.g., Toyota, Honda, Nippon, Sony).
One more point. This is not being vindictive toward Motorola. I have never worked for Motorola nor have I ever known anyone who worked for them. In the early 1980's I was a shareholder of Motorola for a very short period of time and the stock did okay for me. Just trying to illustrate a point from a telescopic view.
