Continuous Improvement of Productivity and Quality with Lean Six-Sigma: A Case Study

Abstract

Continuous improvement of productivity and quality is a potential requirement of any competitive organization. Lean six-sigma is known as the useful and popular method to do it. In this paper, a case study in the mechanical manufacturing process would be presented as a successful implementation. The seven quality control tools would be integrated in specific systematic steps of the PDCA cycle and DMAIC process, and lean technology. The case study shows the promising results on improvement of productivity and quality of a mechanical production line. It could be considered to implement for other production or assembly line in other fields such as electronic assembly line, garment line, and furnitune assembly line.
