Abstract: Purpose of this study is to propose a Lean Six Sigma model that will be applicable for manufacturing organisations for waste management and the same has been implemented in a foundry SME unit. A lean manufacturing model has been proposed, where the various phases of Six Sigma, i.e., define, measure, analysis, improve and control, are reinforced with the tools of mean manufacturing. Further, the same has been implemented in a machining organisation. After the implementation of the advanced Lean Six Sigma model, significant improvement in the scrap rate and reduction of reworking has been observed. A unique Lean Sigma model that will be applicable in modern manufacturing organisations for the purpose of waste management has been developed.

Keywords: lean manufacturing; Six Sigma; lean Six Sigma; case study; waste management.
