Lean Six Sigma Green Belt

Lean Six Sigma Green Belt training combines Lean and Six Sigma tools and methodologies to deliver a powerful toolset. Vector International’s “Teach-Apply-Review” (TAR) format reinforces key Lean and Six Sigma concepts with an emphasis on application and proficiency development. Furthermore, the weeklong application of tools, through team-based case studies, in class exercises and process improvement simulations, are embedded in every course to develop skills and tool proficiency.

The Lean Six Sigma Green Belt classroom course is conducted over a two weeks period  with  a total of five (5) contact days ( or 40 contact hours) of in class instructions.  Additionally, course participants are required to complete  team-based problem-solving exercises for an additional 20-25 hours.

The Lean Six Sigma Green Belt self-paced course offers an engaging, interactive format that stimulates learning through active learning.   Course registrants are given twelve (12) months access to the online course content and are able to pursue the course at their own pace and on their own schedule.

The Lean Six Sigma Green Belt course builds on the fundamentals of the White Belt and Yellow Belt Lean Six Sigma training seminars.  Course participants will finish with a solid grasp of Lean Six Sigma tools and with the ability to apply these tools to drive improvement in critical business processes.



Lean Six Sigma Green Belt candidates are fully trained in the Lean Six Sigma methodologies and basic Lean and statistical tools. The certified Lean Six Green Belt professional may lead fairly straightforward projects or serve as a key member on project teams that are led by a Black Belt. Typically, the Lean Six Sigma Green Belt trained practitioner is one who:

Many managers have completed this higher training course and have walked away with increased confidence and a firmer grasp of the basics, allowing them to be able to better apply these important and profitable methods of management. This particular training is also the perfect foundation for those managers and executives who wish to integrate the principles and philosophy of Lean and Six Sigma in all aspects of their operations.

While this particular training is complete in and of itself, it also prepares candidates to pursue the Lean Six Sigma Black Belt certification level. This next level of training involves three additional weeks of intensive hands-on training that runs over a three month period. Candidates who have not completed the Green Belt level training will complete the Black Belt level program in four weeks that extends over a four month period.
