Since the mid-1980s, many American companies have been very vocal about touting the effects of Six Sigma quality improvements. Motorola, who is largely responsible for much of the modern look of Six Sigma, was in dubious financial shape and customer satisfaction until the results gleaned from developing and implementing a Six Sigma plan helped to make them one of the leaders in their field. Hundreds of other companies have since developed Six Sigma quality programs of their own.

Many individuals have contributed to the ongoing success and adaptation of Six Sigma as a business methodology. Since it is so adaptable, Six Sigma has found a home in many different kinds of businesses, including health care, industry, IT, and financial companies. As many of these companies may attest, Six Sigma can create dazzling results and drive company success.

Six Sigma quality ideals state that for every million parts that are produced, only 3.4 parts will suffer from defects. At this level, product design can move ahead at a much more rapid pace that at traditional quality standards, customer satisfaction can improve dramatically, and profitability may also rise to unexpected levels. Six Sigma programs accomplish these initiatives by applying a holistic view of business, and systematically analyzing hard data about business practices.
