SIX SIGMA MODEL TESTING IN OPTIMIZING MEDIUM-SIZED COMPANY PRODUCTION PROCESS
The aim of this paper is to test Six Sigma concept developed to optimize the manufacturing process for a company with about 200 employees. This test includes process monitoring, using statistical process control charts, and analyzing collected data for two different periods, before and after DMAIC methodology application. Dominant defect and its causes had been identified and it was found out that the process was not under control. Implementing improvement measures, dominant defect was eliminated but this didn’t enable to put the process under control. As a conclusion, the test indicated that the model is effective but it takes more iterations to achieve the desired state.
