The Green Belt Training from SSGI has been the best value I’ve found. Not only in regards to affordability, but the content rivals many other competitors. I’ve taken Green Belt certification from my employer, one of the leading outsourcing companies in the industry, and found while it contained great information lacked the case studies that help make the concepts easy to comprehend. The case studies come from some of the most esteemed and innovative companies, which demonstrates that no matter what industry you perform, Lean Six Sigma can be applied. With the course comes everything you need to prepare for Green Belt Certification: flash cards, study guide, course material, and even practice exams. I highly recommend this course to anyone who is interested in process improvement or looking to add value to their professional portfolio.
