Frequently Asked Questions

How many study hours do you need to complete an online Lean training?

That depends on the training. Participants require an average of 8 study hours to complete the White Belt training. Our online Black Belt course requires an average of 64 study hours.

Can I earn multiple Lean or Lean Six Sigma Belts at once?

Absolutely, we offer three discounted bundles for this. Each with a different final level. With these, you earn multiple accredited belts in a single Lean or Lean Six Sigma training course. The advantage is that, thanks to this approach, you build upon the knowledge you have already acquired. If you choose Upgrade packages, you do not need to redo the exercises you have already completed.

What is the difference between Lean and Lean Six Sigma?

Although they are often mentioned in the same breath, both methodologies have a different focus. The shortest answer? Lean focuses on speed, Six Sigma on quality.

Lean revolves around eliminating waste. The goal is to design processes in such a way that an optimal ‘flow’ is created and customer value takes center stage. You remove everything from the process that does not add value (such as waiting times or duplicate work).

Six Sigma is a data-driven method that focuses on reducing variation. The goal is to prevent errors and make processes highly predictable and stable through statistical analysis.

How can I pay for a Lean or Lean Six Sigma training?

You pay one fixed price per Lean or Lean Six Sigma training course or total package. No hassle with subscriptions. So you can pay for the Lean course of your choice immediately online via iDEAL or credit card. You can also pay in three installments (iDEAL-In3).

What educational level do I need to take an online Lean training?

We do not require a specific educational level for our Lean or Lean Six Sigma courses. However, it is important that you are interested and motivated to take an online training course.

How does an online Lean training work?

When you register for an online training, you receive a personal login code. You can go through and complete the Lean or Lean Six Sigma training at your own pace, wherever and whenever you want. You decide entirely how long you take to complete a course. Having trouble with something? Our Lean specialists are happy to help.
