Lean Six Sigma Green Belt Black Belt Training

Six Sigma (6σ) is a set of techniques and tools for process improvement. Six Sigma seeks to improve the quality of process outputs by identifying and removing the causes of defects (errors) and minimizing variability in manufacturing and business processes.
It uses a set of quality management methods, including statistical methods, and creates a special infrastructure of people within the organization ("Champions", "Black Belts", "Green Belts", "Yellow Belts", etc.) who are experts in these methods. Each Six Sigma project carried out within an organization follows a defined sequence of steps and has quantified value targets, for example: reduce process cycle time, reduce pollution, reduce costs, increase customer satisfaction, and increase profits. These are also core to principles of Total Quality Management (TQM).

The term Six Sigma originated from terminology associated with manufacturing, specifically terms associated with statistical modeling of manufacturing processes. The maturity of a manufacturing process can be described by a sigma rating indicating its yield or the percentage of defect-free products it creates. A six sigma process is one in which 99.99966% of the products manufactured are statistically expected to be free of defects (3.4 defective parts/million), although, this defect level corresponds to only a 4.5 sigma level.

Since 2013, we offer together with our partner Moresteam.com the eLearning course for a "Trained Green Belt" degree.

The Black Belt (BB) education can be done

  • online (without a project), respectively
  • in a company (2 projects + exam).

Interested students have to arrange for BB projects in advance.

Online training leads to the degree “GB/BB Trained”; project work leads to the degree “GB/BB Certified”.


  • Enrolled WHU student in either FT-MBA or PT-MBA.
  • Enrolled WHU students having successfully passed the "Industrial Excellence" course.

If you are interested in one of these courses and have further questions, please contact us.
