I am taking six sigma black belt certification (service) from Michigan University.
Do you support the certification preparation for them?
Thanks,
Hi Mohammad,
Yes, I believe the material here can help you prepare for the University of Michigan Lean Six Sigma Black Belt certification, including the transactional/service track.
I reviewed Michigan’s published Black Belt curriculum and Body of Knowledge and compared them with the ASQ and IASSC Black Belt Bodies of Knowledge. There is a great deal of overlap in the core material, including DMAIC, Lean, process mapping, measurement systems, process capability, hypothesis testing, regression, Design of Experiments, FMEA, statistical process control, control plans, and project management.
There are some differences in emphasis, however. Michigan’s transactional/service program uses examples and case studies from office, service, healthcare, and other transactional processes, while ASQ and IASSC organize and weight their Black Belt material somewhat differently. Michigan also has its own certification exam and project requirements.
So, while my materials were not created specifically for the University of Michigan exam, they should be very useful for learning and practicing many of the Black Belt concepts you will be tested on. I would use Michigan’s course outline and Body of Knowledge as your primary checklist, then use my materials to strengthen your understanding and get additional practice on those topics.
You can find my Black Belt study resources here: Six Sigma Black Belt Study Guides.
If you want more structured preparation and practice, you can also look at my Pass Your Six Sigma Black Belt program. Again, I would pair it with Michigan’s specific curriculum rather than assume that every topic is weighted exactly the same way on their exam.
Best,
Ted
