DMAIC Six Sigma definition and an analytical implementation: car industry case studies

the purpose of this paper is to introduce DMAIC procedure under six sigma concepts and the way to implement such a methodology in a real case in order to achieve continuous quality improvement. Six -sigma is one of the most advanced managerial approaches to obtain drastic improvements in the process performance. Nowadays six sigma systemization has become a common quality-based tool used in any industry to achieve cost reduction and customer satisfaction. Six sigma methodologies would be categorized in two main approaches, DMAIC (continuous improvement) and DFSS (deep re- engineering of new products, service or process).this paper critically investigates the role of DMAIC procedure to improve and sustain the quality as well as integrating the theoretical six sigma concepts and the practical lessons learned from real successful DMAIC implementation projects . DMAIC (Define-Measure-Analyze-Improvement-Control) is a kind of problem solving approach employed as a quality strategy by the aim of continuous improvement .in this study, it has been tried to highlight how to DMAIC the process in real cases ,then to provided solutions and further achieved results would be obtained.
