So this is the stage I’m at at the moment! I want to upgrade my knowledge and be a Black Belt though, so that I can lead Six Sigma projects.
Green Belts are part time Six Sigma professionals, who are skilled in Six Sigma, but usually work in the Six Sigma teams, rather than run the projects (a role usually reserved for Black Belts, although Green Belts can run projects with Black Belt supervision). It can be a stepping stone on the way to being a Black Belt, or a role for people who want to be involved in projects, so that they can bring their new expertise back to their main role, and help spread process improvement knowledge throughout the business.
Green Belts have usually had at very least a week’s training, and so have fairly thorough Six Sigma skills, although still falling far short of the Black Belts. They can however help run the projects and keep them on track, and do specific high level tasks for the Black Belts. Green Belts generally spend about a week (full time) training to be a Green Belt, and may take part in projects during that time.
WHAT DO GREEN BELTS DO?
Generally speaking green belts will have roles in the company that have nothing to do with Six Sigma, which will take up most of their time. They’re Six Sigma part timers, who have a lot of the skills, and will usually spend on average about one day a week working on projects under the supervision of Black Belts.
You will have responsibility for:
- Having a thorough knowledge of Six Sigma
- Helping others in your organization to improve their Six Sigma skills
- Discover and recommend potential Six Sigma projects
- Lead small Six Sigma projects
- Work on larger Six Sigma projects under the direction of a Black Belt
- Completing regular Six Sigma projects to maintain your knowledge (Green Belts only spend a relatively small proportion of their time on projects compared to Black Belts, so it’s important that it remains a priority and skills are kept current)
WHAT WILL YOU LEARN?
A Green Belt should have a good understanding of Lean and Six Sigma methodologies, such as DMAIC, FMEA, Pareto Analysis, SIPOC, and Z-transformations. You aren’t expected to have the detailed knowledge of all tools that a Black Belt would, but you should know enough that you can complete a simple project yourself, and be of great use to a Black Belt on more complex projects.
HOW DO I BECOME A GREEN BELT?
The easiest way is to see if your workplace runs a scheme, as it would be cheapest if they can put a large number of people through the course at the same time. If you’re self-training, online is probably the best value for money. You sometimes get a discount if you sign up for Black Belt at the same time.
Depending on who you train with, the training usually lasts between five days and five weeks. It will usually involve several examinations, and you may need to prove that you have worked on Lean Six Sigma projects.
