RWTH Certificate Course Six Sigma Green Belt

Achieving Sustainable Improvements in Companies

During the certificate course the participants are taught to improve company processes and to identify hidden potentials. With the Six Sigma's DMAIC, they can filter out, measure, implement and apply key improvement measures to other business areas.

Course Contents

Methods for structuring problems, tests of hypotheses and creativity techniques
Statistical tools for process and problem analysis
Management and elaboration of quality improvement projects with Minitab
Practical application: innovative case studies and company-specific project

Group of Participants
Project leaders, quality managers, experts or executives in the service or production industry with at least one year of professional experience

Admission Requirement
Participants must have the opportunity to complete a qualifying Green Belt improvement project at their company and have at least one year of work experience.

Six Sigma offers a framework for action in the systematic planning and effective execution of sustainable improvement projects based on the DMAIC cycle. With the embedded methods, root causes for difficult problems in processes can be identified, allowing sustainable solutions to be developed based on statistical analyses. Measurable results have been primarily achieved in the areas of process costs and waste reduction as well the reduction of throughput times.

The course consists of two presence modules of four days each and a project phase that takes place between the two modules. In the two attendance phases, knowledge is built on the basis of lectures, group work and case levels and practiced with the statistical software Minitab on the institute's own computers.

In the practical project phase, the participants carry out an independent Six Sigma improvement project in their company.

Examination and Certificate
In this certificate course, the participants have to take part in two exams in order to receive the RWTH certificate: First, a 90-minute multiple-choice exam is taken. After that, the participants have to present their Six Sigma project. Finally, the participants receive the official certificate "Six Sigma Green Belt" of the RWTH Aachen University. This course certificate gives detailed information about the scope and content of the course.
