“Belt” Titles used in Lean Six Sigma
As we all know that there are different levels of certification in Lean Six Sigma and these levels have been associated with “Belt” titles. It’s a very obvious question that why the levels here have been associated with the titles used in Martial Arts? That is because of the association of discipline and rigor in Lean Six Sigma similar to the martial arts.
You would find four commonly used belt titles in Six Sigma Certification and they are Yellow Belt, Green Belt, Black Belt and Master Black Belt. However, the most basic level in Lean Six Sigma is sometimes called as “White Belt”. A White Belt understands the theoretical aspects but virtually no application knowledge of the Lean Six Sigma concept. One could say this is an entry level awareness program. Let us understand one by one, the four belts mentioned above.
