The DMAIC methodology

The DMAIC methodology is a popular problem-solving framework that is used to drive process improvements and achieve measurable results. Businesses can improve efficiency, quality, and customer satisfaction by using this structured and data-driven approach to identify, analyse, and solve problems.

DMAIC can be applied in almost any improvement initiative, ranging from a 5-day Kaizen event to a 5-week problem-solving project, or even a 5-month organisationwide improvement programme. This versatile improvement approach is adaptable to various scales and durations, without being constrained by specific magnitudes or timeframes.

About our Green Belt course

The ability to permanently solve problems is one of the most highly valued skills in any organisation. This is exactly what our Lean Six Sigma Green Belt course will make you proficient at. During our course, you will be taught how to uncover the root cause behind a problem, and ensure improvement initiatives are always on target. This is why Lean Six Sigma practitioners are in great demand; they solve issues through substantiated research and prevent fire-fighting; they create solutions that stick.

Our course is designed to enable you to put your newly acquired knowledge and skills into practice. For this reason, the course focuses on the practical application of Lean Six Sigma rather than only going through the theory of all tools.

Green Belt course

Consequently, our Green Belt course consists of 2 parts. The first part is the theoretical training which can be provided both in a classroom and online. This part ends with an green belt exam on the last day of your training. Successfully passing the exam leads to certification which evidences the completion of the theoretical training. The second part of the course is a project you conduct in your work environment.

In many cases, delegates appreciate coaching during their project. As an option, we can provide project coaching during the project. Naturally, delegates can also opt for coaching provided by an internal Continuous Improvement professional.

Our experience is that when delegates have little expertise in improvement projects, coaching can be very conducive to a successful project.

Getting certified

The value of your Green Belt certificate

Successfully completing one of our courses is awarded with an internationally recognised certificate. But what exactly determines the worth of a certificate? We explain why a certificate from The Lean Six Sigma Company is of a higher standard than others on the value of your certificate page.

Frequently asked questions

Can I enrol and join a course without any prior experience or knowledge of Lean Six Sigma?

Every course we provide assumes our participants start the course without any understanding of the Lean Six Sigma methodology. It starts with the fundamentals and explains every topic that is mentioned without assuming prior experience. During the course, you will carry out simulations and exercises to help you develop your knowledge. If you choose to carry out a project as part of your course, you will be coached and assisted by one of the (Master) Black Belts of The Lean Six Sigma Company to help you get started.

Should I go for a Green Belt or Black Belt course?

This depends on your goals and what you intend to achieve. If you would prefer to employ Lean Six Sigma on a part-time basis, for example alongside other work, the Green Belt course would be the best choice. If it’s your aim to work with Continuous Improvement and Lean Six Sigma on a full-time basis, then the Black Belt course would be the right pick.

Is a Lean Six Sigma course relevant to my career phase?

Lean Six Sigma is a methodology that one can start using during any career phase and this course is the ideal starting point. Even as a beginner, your work can add tremendous value. Lean Six Sigma can serve as an addition to your current work, replacing a part of your existing responsibilities. Or it can become a new full-time career, depending on the course you choose.


Green Belt vs Black Belt

The main difference is the scope of your projects. Green Belt projects are usually aimed at solving issues that affect a single department stakeholders. Black Belt projects tend to tackle long-standing, complex issues that cross departmental lines and affect different stakeholders. The responsibilities of a Green Belt align with those of a project manager. Black Belts carry more responsibilities and take a more active, leading role where they direct other Green Belts during projects.

How does the Services course differ from the Manufacturing course?

The Services course is most fitting for those employed in transactional careers such as general administration, logistics, finance, etc. The Industrial course is most fitting for those involved with mass production, machinery, factories and automation). Of course, those who complete the Manufacturing course can still carry out projects in the aforementioned transactional fields.

I find statistics a daunting topic, is a Lean Six Sigma course still for me?

The Green Belt course has very little statistics content, as opposed to our Black Belt course. Yet even the Black Belt courses have designed to start at the very basics, on the assumption that our participants aren’t familiar with anything related to statistics. We realise the idea of working with statistics can sound somewhat intimidating, but our trainers have helped thousands of participants understand (and find their interest in) statistics. Additionally, we offer complementary courses and several videos on our MyTraining™ platform that will help you prepare for, or repeat, specific exercises.

Do you offer any evening- or weekend courses?

The Lean Six Sigma Company strives to organize its courses during normal working hours.

This is a conscious choice in order to avoid interfering with the private lives of our participants and to get them used to the idea of working with Lean Six Sigma during typical working hours, and continue this habit once they complete the course.

However, some local exceptions apply. Please reach out to to the helpdesk in your region if you have any questions

Do you offer courses in other languages?
