In its broadest sense Six Sigma is a methodology that firms can use to improve the output quality of a process. Six Sigma has its roots in the repetitive processes of manufacturing; however, the same tools can be used in any business process from hiring new people to effective product design and marketing plans.

The foundation of the Six Sigma program is statistics; sigma stands for standard deviations from the mean of a data set in other words a measure of variation, while Six Sigma stands for six standard deviations from the mean. When a process reaches the six sigma level that process will be running close to perfection, producing a mere 3.4 defects per million. By using statistical and analytical tools firms can reduce the amount of variation in a process by removing the causes of variation therefore increasing the output quality of the process.


Jim Collins€™ advice to start with the right people is definitely applicable here. Implementing Six Sigma requires having the €œright people in the right seats€ to be successful.[2] Six Sigma is no different. Studying some of the companies listed above will prove that having the right people with the right skills and a shared vision is the foundation for success. The key players of the Six Sigma team are the:

1. Champion: (Usually upper management/ executive officers) The Champion is the person responsible for instilling the vision of Six Sigma and communicating it across the firm. The Champion should receive Six Sigma training in order to be an effective leader. While most likely not as knowledgeable in the use of specific tools in Six Sigma, a Champion must have an understanding of what the Black and Green Belts are doing in order to relay updates and accomplishments to upper management and throughout the company. The champion also assists the Black Belts by dedicating resources, assists in choosing projects, and is the advocate for the Black and Green Belts.

*Some programs distinguish between Champion and Executive leadership, it€™s up to you.

2. Master Black Belt: A master Black Belt is a Black Belt that has had extensive experience with the Six Sigma methodology. When a firm first tries to implement a Six Sigma program it may be necessary to hire the services of a master Black Belt to help facilitate correct implementation and initial success. The Master Black Belt can act as a coach to the Black and Green Belts by drawing on extensive experience relating past problems and how they were solved.

The Master Black Belt can also evaluate project results and give feedback to Black and Green Belts on performance and implementation.
