Wow! I was looking for a Lean Six Sigma Black Belt certification and was hesitant about the cost of traditional programs. When I saw the GoLeanSixSigma deal on AppSumo, I decided to take a chance, and I'm so glad I did! The training is top-notch. The modules are well-organized, the instructor is clear and knowledgeable, and the online learning environment is fantastic. I feel completely prepared to not only pass the exam but also to apply these principles in my work.
The courses were easy to follow and straightforward - there are several skill checks throughout each course to make sure you understand each key concept. I definitely recommend - it is a great deal and product.
