Six Sigma is a methodology used to improve business processes by utilizing statistical analysis rather than guesswork. Processes are improved by controlling variation and understanding the intricacies within them. This results in more predictable and profitable business processes. Six Sigma is more than "training"; it is an approach based on data and geared toward projects with quantifiable business outcomes. This proven approach has been implemented within a wide range of industries to achieve both hard and soft money savings, while increasing customer satisfaction. For instance, in 1999 GE Capital was able to save $2 Billion with Six Sigma.
