15、ng the best people on their site A Black Belt performs 4 to 6 projects per year with a minimum of 2 years assignment commitment Results in up to $1M savings/year/Black Belt The BB ensures that the specific process (sequence) is followed for each project - Measure, Analyze, Improve, and Control Focus

16、 is on fixing the causes using these tools - Y=F(X) Utilizes problem solving tools provided through Training and MiniTab statistical software (DOE, FMEA, etc.) Some Black Belts are selected to perform Green Belt training,Six Sigma System - Black Belts,Green Belts are the professional, salaried emplo

17、yees, including managers, who are not Champions or Black Belts. They have key roles in deploying Six Sigma. Assist Black Belts in completing sections of their projects Receive detailed training over the next three years to improve their data collection, analysis and problem solving capability Will a

18、pply their learning in their daily performance of their jobs Will broadly use many of the Six Sigma methods and tools, including FMEA, DOE, SPC, etc Will be ready-trained as the first round of Black Belts complete their two-year assignments,Six Sigma System - Green Belts,Management is responsible to help drive the total employee population to a higher level of problem solving profic
