Özet:

Six sigma provides to reduce cost by improving productivity and this method achieves this by focusing on the reduction of both defects and non-value added facilities. This method aims to reach zero defect in the theory improving supply chain processes. For extending and improving the effectiveness of supply chains, the critical processes of these systems must be developped. when the amount of users increase in the supply chain, processes and steps of systems will be more complex. There is an effective and usable method named as six sigma. This perspective aims to provide zero defect in the theory developping stages of supply chain. In the practical and implementation life, it is impossible because of changes, diversification in the life.   This methodology has been chosen as a quality improvement technique to solve the problem in a production and supply chain system for industrial sector. By this way sustainability of Supply chains’ and production processes can be provided and improved continuously. This study aims to present literature survey and overview about this quality method, six sigma and supply chain. This research includes some implementation stories, backgrounds of firms of services and industrial sectors. At the end of this study, it presents a case study of XB company and some suggestions can be offered about the case study according to the results.
