What is the best Lean Six Sigma course?

The core ambition of The Lean Six Sigma Company is to enable companies and organisations to excel in what they do. This is done by transferring Lean Six Sigma knowledge, skills and tools to their employees. Afterwards those employees are able to implement these new skills within the organisation, creating value and striving for improvement across all layers. The transfer of knowledge to employees is done through Lean Six Sigma courses, of which we offer numerous different ones. We can imagine that you may be eager to start, but don’t yet know which course is the most suitable  one for you.

Logically, the most suitable is different for everyone. It depends on the employee’s position in his or her organisation, as well as their goal and current skill set as well as those of the organisation itself. Furthermore, Lean Six Sigma courses will always impact and involve many different participants besides the course participant. To cater to those variables, we have created a variety of courses. In this blog, we will dive into which course is best for whom. Aimed at the Yellow-, Green- and Black Belt courses specifically, with a few special mentions after that. Simply read through and see if you recognise your situation in any of the descriptions. When you do, you will know that course is the best one. To answer the main question of this blog simply and immediately: the best Lean Six Sigma course is the one that matches your organisation’s scope, needs and expectations.

Yellow Belt

Change and adaptation is a vital part of the growth and health of an organisation. Having the will to improve drives this change and adaptation. The Yellow Belt course teaches you how to apply that will to improve in a structured manner. This makes it a great starting point to learn about Lean Six Sigma. The Yellow Belt course ends with an exam after which you will receive the Yellow Belt Certification and, more importantly, gives you the ability to make valuable contributions to your organisation’s continuous improvement cycles.

There is also a Yellow Belt course aimed specifically at the Healthcare sector. This was developed for and in cooperation with the Great Ormond Street Hospital. After proving its value, it has been broadened to be useful outside of its former in-house goal. If you’re a healthcare professional interested in Lean Six Sigma, this is the course for you.

Green Belt

If you’re ready to take your organisation’s improvement culture to the next level, the Green Belt course might be right for you. Following up on the foundation laid by the Yellow Belt course, which is included, you will become the person who dedicates time to process improvement in your unit. The course will teach you how to provide valuable contributions to improvement projects and initiatives within your organisation. This is done through various Lean Six Sigma tools and practices. The course will cover multiple lean topics. Furthermore, you will learn how to apply and work with the DMAIC (Define, Measure, Analyse, Improve and Control) project structure. Thus allowing you to eradicate waste within processes to optimise continuous improvement cycles. All of this is specifically aimed at being applicable in practice right away, making it an empowering and eye-opening course. After completion you will be awarded with the Green Belt Certificate.

Black Belt

Just like in the world of combat sports, the Black Belt Certificate is a sign of those who are the best in their field. After receiving the certificate you will be an all-round Lean Six Sigma professional. This means you will view continuous improvement of processes as part of your profession and are able to function as an expert in the field. The course does not require any prerequisites and as such you can opt for the Black Belt course right away. You will go through the complete Black Belt curriculum and familiarise yourself with all the important improvement methods, techniques, tools and definitions. In addition to this, the Black Belt course will teach you how to apply these Lean Six Sigma methods to your organisation at the highest level.


The Black Belt course will lay a theoretical foundation and subsequently you can apply that theory in a practical assignment. You also have the option, however, to complete the theory first. This often means you can spread your efforts to combine the course with your job more easily.

Service Sector & Industrial Sector

When opting for the Black Belt course you can choose between the Black Belt Service Sector course and the Black Belt Industrial Sector course. The difference is that the Industrial Sector course has an additional two training days. During those two days you will expand your Lean Six Sigma knowledge with the methodologies of Design of Experiments (DoE) and Measurement System Analysis (MSA). These additions allow you to initiate and complete highly complex Black Belt projects which require the DoE or MSA approach, typically in the industrial sector.
