Six-Sigma: a Toolbox for Quality and Management

The students in Quality Engineering and Management (Group for Production and Supply Chain Management) WS 2013-2014 have completed a Six-Sigma White Belt certification under the direction of Six-Sigma trainer, Dr. Reiner Hutwelker ( Combining theory and practice, the simulation, “Codierfabrik,” allowed hands-on application of the Six-Sigma theory, in which student factory-teams produced and delivered products according to customer demand.

After the first round of production, the students applied the quality and management “tools” from the 6-sigma methodology to identify and improve the key processes in their factories. After an animated second round of production and analytical data comparison for the two rounds, the interrelationships between the process inputs and the final quality of the delivered product could be quantified and plotted to show process improvement and highlight areas for further work.

Codierfabrik – Six-Sigma Simulation

Each Codierfabrik created and delivered credit cards according to customer demand, with corresponding production costs and revenues calculated by the software. Any deviation from the customer specifications results in a loss. In the group work after the first round, the students analyzed key process metrics using qualitative techniques and statistical tests to identify the cause of the deviations. Following the DMAIC framework (Define, Measure, Analyze, Improve, Control), the teams performed the steps of process mapping, process analysis, root-cause-analyses, solution development and prioritization. The statistical analyses then allowed the students to see the quantitative effect of the inputs on their factory outputs: Quality, Delivery Reliability, and Cycle Time. The improvements were implemented and a second round was played. Comparison of the results from both rounds allowed the teams to discover further statistical relationships in the data and to see the improvement in their Codierfabrik.

This White-Belt Training allowed the Six-Sigma method to be applied in a practical setting, providing immediate application of the theory. We would like to thank Dr. Hutwelker for his time and the excellent and meaningful sessions, allowing the power of the Six-Sigma methodology to be brought into the classroom, combining theory with practice and some friendly group competition.
