Abstract The monograph deals with the issue of using Six Sigma systematic thinking, methods and tools to eliminate deficiencies in chosen organization in automobile industry. This work is divided into four main parts. First part explains the overview of the current state and it defines the basic term of quality and what Six Sigma is in the area of ensuring quality and potential lack of quality. Then we clarify the basic pillars of Six Sigma, Six Sigma implementation process and tools used in Six Sigma. Furthermore, definitions of Six Sigma, its history, principles, levels, key components and procedure of realization of Six Sigma itself are mentioned in this work. This moves us to more concrete theme which is implementation of Six Sigma at the occasion of decreasing number of scraps (wasters) in the production of silencers in automobile industry. In the second part, we specify the objective of this work and in the third section we suggest the methodology used to solve implementation of Six Sigma which is necessary to help us to meet the goal of our work. The fourth chapter deals with experimental research and results.
