The major role of the Six Sigma Black Belt is overseeing teams of Green Belts, who are responsible for most of the actual Six Sigma work within the hierarchy. For a Six Sigma student to earn a Black Belt, they must master the Green Belt curriculum as well as show that they have a clear understanding of the more advanced concepts of the Six Sigma methodology. Six Sigma students aspiring to become Black Belts must also show that they clearly understand the lean enterprise theory and must also show their understanding of the DMAIC paradigm.
