Lean Six Sigma
White, Yellow, Green & Black Belt
Lean Six Sigma is a management methodology that aims to increase quality, performance and customer satisfaction with lower costs. Its two main focusses are the systematic elimination of waste from every process in the company and only keeping activities that are of value to the customer. Although Lean Six Sigma was created in Toyota, Motorola and GE, its methodology is commonly used in the service sector as well. Throughout our practical courses, you will understand what a Lean way of working looks like and what Lean thinking is all about as you will look for innovative solutions for your real business case study. After completing the course, you will receive an internationally recognized certification that confirms your skills in Lean Six Sigma and enhances your managerial competencies.

I chose this training with a high expectation that it would systematise my previous knowledge and form awareness. The lecturer's style and the training material captivated me. As an operational leader, one of the most important things is learning the lean approach, which we must not only learn, but also practice, develop and use on a daily basis.
This training led me on this path of "continuous improvement" and keeps me on it, as I am constantly drawing on the knowledge I gained at that time. I look back on the methods I learned several times and start projects with the help of what I have learned even to this day. I am grateful to be a part of this training with PwC and look forward to taking it to the next level with Black Belt.

The main advantage of the online course is that you can participate in this course from anywhere, and you can even invite your colleagues from other countries to join the course without the need to travel. It's not only a lecture session; even in an online course, you cooperate most of the time in a team, you try out different methods and work on case studies or work directly on a project under the guidance of a lecturer.

Experienced lecturers will guide you through practical courses where you will solve real business problems and you will also get project templates used by professionals. All this will ensure you not only professional knowledge, but also the ability to apply it in practice.

They are not. Although we mention some production principles, 95% of course participants come from non-production areas (shared services, finance, IT, telecommunications, etc.
Aren't there too many statistics in the course?
No. Our Lean Six Sigma courses are highly practical. We pass the skills and methods on to you that we teach our consultants and that we actually use on our clients' projects. During a Green-Belt course, our goal is to teach you how to understand data and perform basic analysis in Excel so that you can make decisions based on data.
What software tools will we use?
We use the tools available to participants; there is no need to purchase additional software licenses. To map the process, participants can use, for example, Visio, Lucidchart, Diagrams.net or Excel or Powerpoint (Excel for data analysis). It is possible to try basic versions of other tools, such as Celonis for process mining, or PowerAutomate, UIPath community edition and others.
Will I learn to work with Minitab in the course?
We do not work with Minitab in our courses. Minitab is specialised software used mainly in the area of production quality. A single-user license costs thousands of euros and its use in the non-production area is very limited. We will teach you how to perform all the necessary data analyses in Excel. During a Black-Belt course, those interested can try data analysis in Python.
