History

Six Sigma is a revolutionary process developed with the goal to dramatically reduce or eliminate organizational inefficiencies, i.e. defects or non-conformances that translate into bottom-line profits. Six sigma process that has transformed from a long pursuit of control over process and product quality levels. Most people who think of six sigma, think of Jack Welsh the CEO of General Electric who championed the process in late 1995 to change how industry approaches quality. Jack Welsh set out to achieve product improvement goals of $150million though the vigilant use of six sigma methodologies. Jack Welsh launched his effort in late 1995 with two hundred projects and intense training programs. The initiative begun by Jack Welsh was far more productive than he could have imagined with over $320 million in productivity gains and profits.

Six Sigma did not begin with Jack Welsh however; Six Sigma was developed and trademarked by Bill Smith in the mid-1980s at Motorola. Six sigma stemmed from a management’s business strategy with the goal of reducing the defects in production to a negligible level, nearly zero, to increase profit and customer satisfaction. It was here that Motorola modified the standard measure of reducing defects per one thousand to measure the defects per million. There have been many quality initiatives over time that were targeted to analyze and attempt to control process to deliver higher quality.

The very beginning of the measurement standard of six sigma dates even further back to a German mathematician Carl Gauss who (1755 – 1855) who introduce the concept of measuring data or items inside of a normal curve. In the 1920’s Walter Shewart led the forefront for creative management at Bell...
