Many modern-day businesses use various Six Sigma tools to accomplish streamlined business organization and low product deviation. Six Sigma methods and processes began to be developed for use within Motorola's GEG division in the mid-1980s. Since then, many people and many companies have adapted Six Sigma tools and techniques to suit many different kinds of businesses around the world.

As many practitioners of Six Sigma may argue, the most important tool of Six Sigma is the mindset. The way a business views its production, service, and reliability often have a large effect on the way that executives and other employees do business there, a concept that is important to Six Sigma. The adaptability and success of Six Sigma tools have allowed it to evolve from a production line theory to a holistic business philosophy.

By viewing all business and production output as a function of many different input factors, it is apparent that businesses can only affect their output by altering the input. This concept, realized as the equation y= f (x), is central to Six Sigma. Other Six Sigma process tools then allow practitioners to systematically test every possible X, narrow them down to a few key input factors, and develop control methods for those factors. By doing so, Six Sigma teams can reduce standard deviation of a product down to 3.4 parts per million produced.

Software Six Sigma Tools

Other common tools in use with Six Sigma programs today include tracking software and web-based resources. Tracking software is essential to organizing the tremendous amounts of data that are recorded during Six Sigma's thorough middle stages, and for analyzing and ranking the criticality of that data. Web-based resources also aid Black Belts and Green Belts in developing appropriate improvement techniques and control programs.
