Lean Six Sigma is a proven methodology for improving processes, reducing waste, and increasing quality by combining Lean principles with Six Sigma’s data-driven approach. It helps organisations work more efficiently, improve customer satisfaction, and reduce operational costs.

For professionals, Lean Six Sigma strengthens problem-solving skills, leadership capability, and career progression. For organisations, it creates measurable business impact through faster processes, fewer errors, and better decision-making based on data rather than assumptions.

Yes. The Lean Six Sigma Company provides internationally recognised certification based on ISO 18404 and ISO 13053 standards, which define the global benchmark for Lean Six Sigma competence and project quality.

Our certifications are recognised in more than 40 countries and trusted by employers across industries. This means your certification demonstrates not only theoretical knowledge, but also practical capability that is valued in the international job market.

The right Belt level depends on your role, responsibilities, and improvement goals.

A Yellow Belt is ideal if you want to understand the basics and support improvement projects. A Green Belt is suitable if you want to lead projects within your own department. A Black Belt is designed for professionals leading larger, cross-functional improvements across the organisation. A Master Black Belt provides governance and coaching across the organisation. They train, support, and guide Black Belts and Green Belts while building and sustaining long-term continuous improvement programmes.

If you are unsure, feel free to complete our White Belt course, which explains the different roles in more detail, or request our prospectus to learn more about the differences between the course programmes.

Successful deployment starts with leadership commitment, clear business goals, and the right training strategy. Lean Six Sigma works best when it is linked directly to operational priorities such as cost reduction, customer satisfaction, quality improvement, or growth.

Most organisations begin by training key employees at Green Belt and Black Belt level, supported by leadership alignment and project selection. A structured deployment also includes governance, project coaching, and measurable KPIs to ensure long-term results rather than isolated improvement projects.

Lean Six Sigma courses can be followed online, in person, or through a blended learning format that combines both. The best option depends on your schedule, learning style, and whether you are studying individually or as part of an organisational programme.

At The Lean Six Sigma Company, all our advanced programmes, such as Lean Practitioner, Lean Leader, Green Belt, and Black Belt, are instructor-led. We offer these courses in person, online, or as a combination of both.

Additionally, all delegates receive access to our online learning portal, MyTraining, so they can study in their own time and refresh their knowledge after the course. This allows professionals to combine study with their daily work and apply their learning directly and successfully in practice.

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

The return on investment of Lean Six Sigma training is often significant because the methodology focuses on measurable business improvement. Many organisations recover training costs through just one successful improvement project.

Typical ROI comes from reduced process waste, lower operational costs, improved productivity, fewer defects, and better customer outcomes. For Black Belt and Green Belt professionals, project savings often exceed the cost of training many times over, especially when improvements are sustained over time.

Although it is not a formal requirement for projects, Lean Practitioners often create financial benefits of around £25k, Green Belts around £50k, and Black Belts even £100k.

The cost of Lean Six Sigma training depends on the Belt level, training format, level of coaching, and whether certification includes a practical project and examination. Yellow Belt programmes are generally the most accessible, while Green Belt and Black Belt programmes involve deeper training, project coaching, and internationally recognised certification. When comparing providers, it is important to look beyond the course fee and consider accreditation, ongoing support, and the long-term value of a recognised certification. At The Lean Six Sigma Company, you can start with entry-level courses from £200, or progress to more advanced programmes such as Black Belt at £3,500, with all other courses available in between.
