Moon-Bak ChoiNemo Sigma Group, Seongnam, Gyeonggi-Do 463-828Six sigma is focused on quality improvement through variation reduction, while lean is on process flow improvement and lead time reduction by waste elimination. However, lean cannot bring a process under statistical control and six sigma alone cannot dramatically improve process speed. Lean six sigma was developed to achieve faster rate of improvement in customer satisfaction, cost, quality, process speed, and invested capital. In this paper we present the importance of using value stream mapping and suggest a guideline on how to integrate lean and six sigma by is proposed.Keywords: Six Sigma, Lean, Waste, Lead Time, Non Value Added Time, Process Cycle Efficiency, Value Stream Mapping, Lean Sigma Roadmap
