    Hello
    Β 
    I do not know if there is a formal education for anyone of them, from what I understand it is more of a universal understanding for what is what. Here are my beliefs anyway.
    Β 
    Typical duration
    GreenBelt: 6 days
    BlackBelt: 20 days
    Β 
    Main difference I think is leadership, As a Blackbelt you probably have more education (included in the belt training) for project management (often referred as soft sigma).
    Β 
    For the statistical tools I think they are in basic the same, just that BB gets a deeper understanding due to more training.
    Β 
    Saying this a Green Belt may very well have more knowledge and capacity then a BalckBelt if they have good education in leadership and statistics, just that the actual GB diploma doesnΒ’t state that.

    The difference between the GB and BB should be:

    GB are part-time resources (typically up to 30% capacity allocated to Lean Six Sigma) while BB are full-time resources
    GB work on improvementΒ projects which are tend to be more functionally scoped, while BB work on cross-functional improvement projects

    For the most part the difference has to do with the level of knowledge for Experiments.

    In our company, the first two responses are correct.Β  I’m a BB and am fully dedicated for the running of our projects.Β  I work with other plants, R&D and Marketing.Β  I have a few more tools than our GBsΒ but my understanding is a little deeper because I use them more often.Β  Our GBs and YBs only work on a couple of projects a year and about 20% of their time when on a project.Β 
    As a BB I’m expected to be a resource for them as well as run my own projects.

    At our company, the main difference between GB and BB is that BB:
    – is dedicated 100% to continuous improvement, GB less than 10%
    – receives 1 week more detailed training in Minitab
    – receives 1 week more detailed training in DOE
    – supports GB in their projects
    – reports Six Sigma program status to management board
