Abstract
This paper presents the improvement efforts to increase the major performance indicator of the production lines in a chewing gum confectionery. Extensive knowledge of the system under study was acquired through the analysis of the current situation of the system and all the variables involved. With this analysis, it was possible to determine the most influential root causes that prevented a better performance. Having identified the main four root causes, six different strategies were designed and established, which were implemented with their respective control method. The results of the case showed that after only the four months of the project, an increase of 9.45% in the performance indicator was achieved; resulting in a historical record of production rate in the plant.
