Frequently Asked Questions (FAQ).

I already have a green belt certificate. Can I directly register for the black belt course?

Our certification programme follows a clear structure which does not allow skipping of courses. If your certificate is issued by a renowned Master Black Belt and organisation, however, we may offer you a price discount on the lower levels.

Are the exams difficult? What if I don't pass?

If you don’t pass the exam, you will be granted a second chance free of charge. If you don’t pass this second time, you will have to repurchase the respective course. The exams are open-book and clearly refer to the content of the training videos.

How about the project reports? Can they be rejected?

Yes, project reports may be rejected in case of formal errors in either editing or a wrong application of the Lean Six Sigma tools. In that case, you will receive a list of comments for improvement, and you have a second chance to submit your project report to us.

Are the training material and exams in English?

Do I need to submit the project report in English?

How long does the project report need to be? Is it like a university thesis?

The project report can be quite short, but need to provide information on all steps of the Six Sigma DMAIC project cylce. It is not a scientific thesis, but the purpose is to show that you are able to deploy all Six Sigma tools in a correct way.

Do I need to buy other material such as books or software?

We do recommend some books to deepen your knowledge but they are not necessary to master the exams, in particular the Lean Six Sigma Handbook by Thomas Pyzdek and Paul Keller. In terms of software, you may use download R free of charge, or buy Minitab, or use both.

The ability to learn, and translate that learning into action rapidly, is the ultimate competitive advantage.
