On the coffee machine assembly line, we noticed that the production targets were not reached consistently, which caused delays and slower workflow. To solve this problem, we used the 8D method to analyze the assembly and testing processes on the functional stations. The first part of the thesis presents the employed methodology and quality tools. The analysis showed that the main cause of the issue was the long testing time on the functional stations and repeated test steps. As a permanent solution, the amount of water used in the performance test was reduced from 120 g to 60 g. The tests confirmed that this change does not reduce the quality of testing, but it does shorten the average testing time by 22 seconds, which represents 6,5% improvement.
