Abstract: This study proposes the DMAIC Six Sigma approach with an emphasis on value stream analysis to reduce costs and increase capacity for a local manufacturing company in Northwest Ohio, USA. The DMAIC approach and case study demonstrated a broad application and how an organisation can significantly reduce costs, in this case, by nearly $660,000 per year. The paper identifies each stage of the DMAIC cycle and the Six Sigma tools that were applied, including a rigorous value mapping technique. This paper develops a framework that can be used as a template for cost reduction and capacity enhancement training.

Keywords: lean DMAIC; lean six sigma; value stream analysis; lean manufacturing; continuous improvement; case study; USA; United States; value mapping; cost reduction; capacity enhancement training.
