Excellent CSSBB Course; Instructor Simplified Concepts
“CSSBB course from Benchmark Six Sigma is an excellent course for all those who are working towards a certification. The course content covers the Body of Knowledge required to be confident of clearing the certificate exam. The course instructor Mayank not only has a thorough knowledge on the subject but also has the ability to explain very difficult concepts in a very simple and understandable manner. I would strongly recommend this course not only to those aspiring towards a Lean Six Sigma BB certification but also to those interested in research such as Masters and Phd students.”
