Lean Six Sigma Green Belt Certification

Lean Six Sigma Green
Belt Certification


TUM School of Management Executive Education Center is offering the TUM Lean Six Sigma Green Belt certification. The course takes place in partnership with the TUM edX Professional Series: Six Sigma and Lean Qualitative Tools for Quality and Productivity (QPLSx), for participants who have already acquired the TUM Lean Six Sigma Yellow Belt Certificate or who are seeking to acquire it.

Our Green Belt certification is a 100% online program and focuses on the implementation of a suitable real project in the participant’s working environment. The selection and technical supervision of the project must be supported by a manager of the participant in the role of a Sponsor of the project.

Our Six-Sigma Master Black Belt Dr. Reiner Hutwelker supervises the projects methodically in individual coaching sessions and joint group meetings. Each participant will receive 16 individual coaching sessions and will participate in a minimum of 10 group sessions. The coaching covers all phases of the DMAIC, from project selection to its implementation.

Participants will apply important tools of the DMAIC cycle using the free software sigmaGuide and Minitab (trial version allowed). The participant summarizes the results of the application of these tools for each DMAIC phase in a personal Project-Story-Book. The results are evaluated in every phase by Dr. Reiner Hutwelker. With written feedback and individual coaching, errors in the application of the tools are corrected in each phase and options for their use are shown. After the positive evaluation of the results of a phase in the Project-Story-Book, the participant is in each phase obliged to also present the achieved results to his/ her Sponsor. The Sponsor has the last word in each phase and decides on further necessary corrections or the transition to the next DMAIC phase.

This concept ensures the methodologically correct and technically meaningful implementation of the project. This is important because the participant has to prove the financial benefit of the project at the end of the project. A project without implemented solutions or implemented solutions without benefit cannot be certified.

This hands-on approach, combining the theory learned and practiced during the MOOC with individual, project-oriented coaching and technical sponsoring will enable the participant to confidently and effectively start and drive further Six-Sigma projects in his or her workplace and work quickly towards a Black Belt certification.
