One more day to go. Hopefully I can take my Green Belt certificiation exam this evening and have it done with. That's right, I said Green Belt. The Six Sigma methodology ranks the various levels of expertise by belt-level. Yellow Belt, Green Belt, Black Belt and Master Black Belt. There's all the funky sociological hierarchy to go with it. The master black belts push around the black belts, and they in turn like to tell the green belts what to do.
