An in-depth Green Belt course

As a Green Belt, you know what makes an improvement stick. Regardless of the department or challenge you face, you know what to do. As a Green Belt, you are also able to lead project groups or join initiatives with other Lean Six Sigma practitioners, for example during organisation-wide projects. As your work often affects employees throughout the department, change management is also a skill you will become familiar with during the course. This wide range of knowledge and competencies is what makes our Green Belt certificate, as well as its owners, highly valued.

To help you achieve incredible results for an organisation as soon as possible, carrying out a full Lean Six Sigma project is part of your course. This way, you learn to apply your theoretical knowledge in real life situations. During the course, participants learn how to select projects with the highest financial return and lowest effort involved, so that every new initiative adds maximum value. Then, once your project starts, you receive personal coaching from one of our (Master) Black Belt coaches with experience in your field. Your (Master) Black Belt will assist you during your first project and help you take the first steps towards becoming a Lean Six Sigma practitioner.

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 training 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 one of the reasons why Lean Six Sigma practitioners are wanted; they solve issues through substantiated research and prevent fire-fighting; they create solutions that stick.

As a Green Belt, you must involve different layers of an organisation. After all, improvements are still a change, and change must never be a surprise; this creates resistance. Instead, by knowing how to involve key parties and applying change management techniques, you create support for these changes. Turning reluctance into enthusiasm is an important aspect to any Lean Six Sigma project.

Green Belt course

Green Belts are expected to possess a broad range of knowledge and tools. Therefore, choosing the right course is vitally important. A course must ensure that practical experience is part of the programme, in order to help participants bridge the gap between ‘knowing’ and ‘doing’. This is why our complete Green Belt programme includes a project and takes 3 to 4 months. Because only through repeatedly applying knowledge over several months can participants become truly skilled.In the next section, we highlight what specifics the course will offer. This intensive setup has one goal: to make you into a skilled Lean Six Sigma expert. With each phase, your knowledge and grasp of the tools will grow, until eventually, you understand how to achieve your goals as a fully-fledged Green Belt.

Return-on-investment estimate

Results and cold, hard facts are often the best way to justify a purchase. Our courses are no different, and deliver said results without fail. After having trained thousands of participants in the Lean Six Sigma methodology, our findings are as follows: Green Belt projects generate extra revenue and/or save costs in excess of £50.000 on average, often from the very first project. And with each project taking approximately 3-4 months, it is even possible to carry out multiple projects a year.


If it is a course for an entire team you are looking for, then our In-Company pages will be of interest. Our instructors will also host every course we offer to individuals in your organisation.

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?
