Six Sigma

Read this chapter, which gives a clear description of Six Sigma, when it is used, and how to interpret the results.

The Six Sigma Program

Green Belts (GB)

Green belts are new team members that achieve certification after completing training in a Six Sigma course. To complete green belt training, new members must complete a relevant project that utilizes the DMAIC model outlined below. To maintain green belt certification, green belts generally complete DMAIC projects once every twelve months. Green belts are also responsible for:

  • Recommending Six Sigma projects
  • Participating on Six Sigma project teams
  • Leading Six Sigma teams in local improvement projects

Green Belt Projects

Green belts complete six sigma projects while still holding their current job duties. Therefore, a six sigma project undertaken by a green belt could include:

  • Statistical analysis to improve reliability on a reactor within the green belt's current responsibility
  • Root cause analysis and elimination of quality control problems that chronically affect the green belt's department
