About this course

Skip About this course

Every employee is involved in business processes to create products or services. The causes of decreasing customer satisfaction and increasing quality costs are often unknown, so derived solutions often only address symptoms. Six Sigma methods and tools enable a systematic solution of typical process problems and lead to sustainable operational excellence.

Go from Yellow to Green Belt in this project-based Lean Six Sigma course. With the TUM Yellow Belt, you have mastered the body of knowledge of our Green Belt (according to the American Society for Quality standards). Our Green Belt certification requires the implementation of a Six Sigma project (as recommended by the International Society of Six Sigma Professionals), just as driving experience is necessary to obtain a driver’s license.

To earn the TUM Lean Six Sigma Green Belt certification, you will implement a predefined project on environmental littering. The goal: “Improve the cleanliness of areas around selected places in your hometown and control the sustainability of your measures.” To reach this goal you will drive along the DMAIC, accompanied by a Master Black Belt as co-pilot. The route is determined by our navigation software (sigmaGuide). We will stop at every important sigma tool, which you will then apply in practice and document in a project storybook. This storybook will demonstrate the operational excellence of and in your work.

We will guide you through your improvement project. Each DMAIC phase concludes with a project review by a Lean Six Sigma Master Black Belt. With the feedback on your achieved project results, we keep you on track before you start the next DMAIC phase. You will also participate in weekly live sessions online, where we will discuss the tools and logic of Six Sigma in depth and answer any questions. The e-book for the course, Six Sigma Green Belt Certification Project, is included in the course price.

Green Belt Certification: Learners will be awarded the TUM Lean Six Sigma Green Belt Certification after completing this course and all of its requirements, including:

  • Previous acquisition of the TUM Lean Six Sigma Yellow Belt certificate,
  • Application of the sigma tools (sigmaGuide),
  • Documentation of the results in a project storybook,
  • Five graded reviews of the project storybook along the DMAIC phases,
  • Participation in at least 10 open-online-sessions,
  • Delivery of the completed project storybook and the collected data.

What you'll learn

Skip What you'll learn
  • To identify and define suitable Six Sigma project topics.
  • To implement a Six Sigma project along its DMAIC phases with all relevant qualitative and quantitative tools.
  • To evaluate the success of a Six Sigma project with process performance indicators and the derived financial benefits.
  • To apply all relevant DMAIC tools, for example, Project Definition, Voice of Customer/CtQ's, Project Charter, Process Mapping, Cause & Effect Matrix, Hypotheses, and their Statistical Tests, Root-Cause-Analysis, etc.

Part 1: Introduction

Introduction to Six Sigma as a company-wide improvement program, based on a structured approach to linking reality, methods and statistics.

Part 2: DEFINE

Identification and definition of a suitable Six Sigma project, structuring the project field in its core process steps (SIPOC), translating Voice of Customer (VoC) and Voice of Business (VoB) to CtQ’s as most important problems (Y), summarized in a Project-Charter for all stakeholders and supplemented by a stakeholder communication plan.


Input-Analysis and Process-Mapping and -Analysis for identifying the triggering influences (x) of the problems (Y). Determination of the relationships between influences (x) and problems (Y) (C&E-Matrix), as the basis for deriving hypotheses. Operationalization of measurands for influences (x) and problems (Y) in a data collection plan, as the basis to collect a sample of corresponding data.


Data evaluation and graphical display of data, representation of the process performance, in control charts and indices of the process capability, test of hypotheses on the differences between problems (Y1 – Yn) and relationships between influences (x) and problems (Y) up to the analysis of root causes (fault tree).


Development and selection of solutions to eliminate, adjust or circumvent the root causes (x´), specification of solutions as measures, detection of their risks (FMEA) and development of countermeasures, hints for implementation.


Data evaluation and graphical display of data, representation of the process performance, in control charts and indices of the process capability, test of hypotheses on the differences (before vs. after), derivation of financial and non-financial benefits of the improvements, development of a Process-Management-Plan to control the improved process.

Part 7: Project Conclusion

Preparation of the lessons learned, completion of the Project-Story-Book and review of this project documentation by our Master Black Belt for certification.

Learner testimonials

Testimonials from our Business-Certification Projects:

Ana F., Norway : “Since I started my Lean Six Sigma Green Belt program through TUM, I went through a process of learning by doing with heavy support of tools and coaching sessions made available by TUM. The program is set up in a logical, methodical and very well-structured way, but at the same time, it is challenging me to step up by taking responsibility and leadership over my project. My work is now more visible to management and I am sure to be able to provide them solutions rather than just problems. Continuous learning allows growth and for those interested in developing their knowledge in Six Sigma, this program simply perfect.”

Brad B., USA : “The Lean Six Sigma Green Belt Certification program through the Technical University of Munich is exciting and challenging at the same time. This program involves a real life 6 months to a year project that impacts our career and helps us show our leadership that we can enhance our education and apply what we've learned in a project at work. With a focus on Lean Management, our team can work smarter and not harder.”

Christopher L., USA : “ The Lean Six Sigma Green Belt program at TUM requires students to actually apply the information learned from the Yellow Belt program to a real work project. Choosing TUM over ASQ certification was a simple decision once I learned that you get to implement your own project at TUM. Running into the real-life problems and scenarios during each phase of the project and having Dr. Reiner Hutwelker available one-on-one to coach you through the tough times has been an extremely valuable experience. The professional experience you will gain coupled with the flexibility of the program on an online platform make this certification course ideal for all types of students all across the world.”

Helga S., Oman : “I've been on the Lean Six Sigma program since June 2017, first completing the Yellow Belt courses and now working on the Greenbelt. The academic units were challenging and well structured. The practical part so far has offered great support and one on one interaction with Dr Hutwelker. The coursework slots in perfectly with the implementation of the project in my company so my company are benefitting greatly by having the input of a Master Black belt. I highly recommend this course and particularly Professors Ott and Hutwelker.”

Karim H., China : “I work for a manufacturing SME in the fast-paced and competitive country that is China. As such, access to knowledge and industry best-practice is necessary yet challenging to get. The Lean Six Sigma Green Belt Certification from TUM allows me to apply the knowledge gathered through the Yellow Belt program on a real case and with the continuous support of Dr. Reiner (Master Black Belt). In a nutshell, I am improving my company’s products and services while extending my knowledge and my colleagues. Given the size and resources of my company, this is not something I would have had access to otherwise.”

Frequently asked questions

Are Yellow Belt (YB) certificates from providers other than the Technical University of Munich (TUM) also accepted to apply for the TUM Green Belt (GB) certification?

No. Our TUM YB Body of Knowledge includes the theoretical knowledge up to a GB level, and this is necessary for our GB certification.

How long does the YB Certification take?

3 courses, approximately 3-5 months to complete all three, self-paced.

How long do I have to wait to start the GB course after completing the TUM YB?

As soon as you have received the edX YB program certificate, you are eligible to start the GB course. You do not need to wait for the additional TUM YB certificate, which is generated three times per year, to start the GB course. After you start the GB course, you will be prompted to enter your YB program record in the first assignment, before you can access the course material.

How long does the GB project take to complete?

Speed is not a criterion of success for us. Typically, GB certification projects should be completed within half a year. The flexibility of this self-paced course allows you to complete your GB project in more or less time, as you need.

May I work on a topic other than the predefined standard project for certification?

No. Individual project topics require indiviual coaching sessions. We cannot offer these in this context. However, there is the possibility to acquire the GB certificate with an individual business project. For more information, please contact the course instructor.

May I submit an already completed project for certification?

No. You must implement a new project, because this is the only way we can ensure that you master the methods and tools.

Will I receive support to introduce my project to the official garbage removal authorities of my city?

An official letter from TUM will be provided upon your admission to the course.

May I use tools other than sigmaGuide and the Project Story Book?

No. Our learning material is based on these two tools.

Can I become GB certified even if I cannot complete my project successfully?

No. We want to make sure that all DMAIC phases have been completed, all relevant tools have been applied, and the benefits of the project have been demonstrated.

How long will it take to obtain the TUM GB certification after completion of the course?

Please allow four weeks for review of your Project Story Book and your delivered data file, as well as the preparation of the certificate.
