Abstract: Six Sigma is a well-known concept which means perfection. A process of production to three sigma makes 3.4 defaults/million unit, whereas six sigma means for us perfection. We used it now to mean type of specialised training, aiming at the attack of very high objectives for processes improvement. Six Sigma is a method of continuous improvement and elimination of non-quality, passing by cycle DMAIC: to define, measure, analyse, innovate and control carried out by a project team. In this paper, we propose a new practice of Six Sigma for reduction of the number of non-conformities and minimisation of the number of customers| Complaints for KITAMEUBLE industry.
