A lean six-sigma manufacturing process case study

Lean Six-Sigma - LSS is an approach that has been proven and applied in many manufacturing floor. Initiated in the automotive industry, continuous improvement were implemented to improve the manufacturing process change. LSS is used to elaborate a case where lean six-sigma principles can be adopted for the improvement process. Benefits of LSS are to reduce production lead time and to decrease work in process inventory. Six-sigma focuses on process flow and pressures to minimum variations. Value Stream Mapping-VSM is one of the lean tools used to recognize and to reveal problems lean, such as the sources of waste and find the hidden waste. VSM describes all activity of process, both value added and non-value added activity. Therefore, a new VSM is corrected to redesign a new lean process flow through process improvement with elimination of the root causes of waste. This paper proves the using of LSS principles and its application in case study for a product (gas stove).
