Especially in improve phase of DMAIC cycle, different improvement tools are used like 5s, supermarket and line balancing etc. By using these it has been possible to improve productivity by reducing defect rate. This research work has been carried out in a fan manufacturing company to show how to improve its productivity and quality by using Six-sigma.
