Definition of Certified Six Sigma Black Belt (CSSBB):
Certified Six Sigma Black Belts (CSSBB) are those individuals who have displayed proven knowledge and expertise in implementing Six Sigma. This involves both “textbook” knowledge of the subject matter (methodologies, tools, principles, and related topics such as leadership and change management), as well as real-world, successful application of the methdology and tools in more than one Six Sigma projects.
An individual can be become a Certified Six Sigma Black Belt (CSSBB) in a variety of ways: from a not-for-profit society, from a consulting company, or from their private company (e.g., GE, Motorola, etc.). No one way is necessarily better than another, however, it is widely accepted that private companies with mature Six Sigma programs serve as the best vehicles for certification. In other words, this becomes the most valuable certification in marketability of individuals who become certified.
What matters most, arguable, is the results the Certified Six Sigma Black Belt (CSSBB) has delivered and can prove to a potential new employer.
