A conceptual examination of Lean, Six Sigma and Lean Six Sigma models for managing waste in manufacturing SMEs

Purpose The purpose of this paper is to examine and evaluate various Lean, Six Sigma and Lean Six Sigma (LSS) models proposed by various researchers, which have been implemented in manufacturing organizations. Design/methodology/approach The present study has followed three major steps in methodology. In the first step, pooling of various research articles has been done, followed by development of the primary results. At the final step, analysis and development of the LSS model have been performed. Findings This paper evaluated and examined various models of Lean Manufacturing, Six Sigma and LSS and developed an advanced LSS model that can be deployed in any manufacturing organization with the purpose of scrap reduction. Originality/value The findings of this study will assist shop floor managers to implement an LSS model in their organizations, which can effectively reduce the waste and enhance the overall productivity and quality of the manufactured products.
