ABSTRACT
Purpose – The aim of this work is the implementation of Six Sigma (SS) method on a company
operating within aviation industry and the statistical evaluation of the methodological effects on the
performance of company. SS implementation was conducted in order to improve the manufacturing
process which caused a bottleneck within the company. SS project executed in XYZ Company serves as
basis for the implementation. The university academically provided support to XYZ Company during
the realization of the project. The results of the work will be shared with manufacturing industry
professionals and universities via this symposium and related manuscript. Target audience includes SS
implementers, continuous improvement operatives, industrial performance leaders and researchers at
universities, working on Lean Management. The bottleneck was eliminated with the SS project
conducted within the frame of close cooperation of the university and the industry and an increase
regarding the work performance of the company was achieved. Statistical techniques were used much
more actively in the company by the help of the academic support provided by university. This work is
related with production industry and the data were provided by XYZ Company, which operates on an
international scale. The company seeks to ramp up its competitiveness and capabilities in the global
market. SS method is used intensively in the manufacturing industry. The process surveyed in this SS
project is specific to the company. The SS project revealed that not only layout or method change but
also modifications on the machine design were required. The changes were applied in line with this
requirement.
