Four reasons to choose us

In the 90s organisations were applying either Lean or Six Sigma. In 2002, the first literature about combining the methodologies was published. The Lean Six Sigma Company was founded in June of that year and our founders strongly believe in the benefits of combining Lean and Six Sigma

A lot has changed since 2002. Today Lean cannot be imagined without Six Sigma any longer and globally a large community has emerged which focuses on the combined methodologies.

Over the past 16 years, thousands of professionals and hundreds of companies have realised their Lean Six Sigma ambitions through our courses and certification.

1) Internationally accredited and recognised certification

Our Lean Six Sigma courses are acknowledged internationally.

We were the very first provider with an IASSC accreditation in Western Europe and we are, to this day, the only provider with an official Postgraduate accreditation for the Black Belt training (The Netherlands and Belgium).

The Lean Six Sigma Company provides courses in the United Kingdom, Canada, France, Germany, Switzerland, Italy, The Netherlands, Belgium, Ireland, Serbia, Slovenia, Portugal and Spain. 

Content of the courses is in accordance with international standards (ISO18404, IASSC and ISO13053)

Our courses are provided in English, French, Spanish, German, Italian, Portuguese and Dutch.

2) Continuously improving our courses

“Practice what you preach” and we preach quality. Spearheaded by our Master Black Belts, training courses are continuously improved. Having experience with hundreds of organisations, we have examples from virtually every industry.

Historically Lean Six Sigma has its roots in the manufacturing industry. Many of our Master Black Belts were certified by manufacturing companies such as General Electric, Toyota, RioTinto, DuPont and Avery Denison. 

In addition, we have worked with many transactional businesses ranging from financial services to healthcare. We have developed specific training programmes for service-oriented industries. 

Having such a large network of Master Black Belts, we pride ourselves in the depth of the knowledge available. Monthly, Master Black Belt meetings are organised to share experiences and exchange latest developments. Bi-annually knowledge sharing events take place throughout Europe to ensure we provide the best training sessions that meet market requirements taking the latest trends into account.

3) From learning objectives to exams

Naturally, the content of a course is extremely important but we believe the teaching methods employed are of equal importance. We have invested substantially in developing appropriate learning methods.

The content of the course is laid down in well-defined learning objectives in the Body of Knowledge for each separate course. Our starting point was to classify the learning objectives according to the six levels of knowledge complexity (Bloom’s taxonomy).

1)   Memorise
2)   Understand
3)   Apply
4)   Analyse
5)   Evaluate
6)   Create

Using a pedagogical matrix developed especially for The Lean Six Sigma Company, the learning objectives and corresponding knowledge complexity were translated into specific teaching methods.

As a result, depending on the subject matter, different teaching methods will be employed. This leads to interactive course days, full of examples and practical exercises rather than dry and lengthy powerpoint lectures.

4) Focus on practical applicability

It is our mission that Lean Six Sigma professionals we certify can make valuable contributions to continuous improvement initiatives upon passing their exam. 

Focus is on being able to ask the right questions and find the right tools required to provide the answers. The ability to apply Lean Six Sigma tools in practice is what we focus on, without losing sight of the theory behind Lean Six Sigma methods and tools. 

We are proud of so many of our certified Lean Six Sigma professionals who have been able to make a substantial impact either academically or in their working environment.
