Black Belts (Program Managers)
Black belts work full time on six sigma projects. According one Six Sigma authors, black belts should equal about 1% of the number of employees in the organization. It is expected that a black belt manages four projects per year for a total of $500,000 to $5,000,000 in contributions to the company's bottom line.
Master black belts have advanced knowledge in statistics and also have knowledge in the technical fields. They provide support to black belts.
