Development of structural equation model for Lean Six Sigma system incorporated with sustainability considerations

Abstract

PurposeThe study aims to describe the development of a structural measurement model using structural equation modeling technique to validate the association that exists between Lean Six Sigma (LSS) and sustainable manufacturing strategies.Design/methodology/approachBoth LSS and sustainable manufacturing aim at improving the firm’s business competitiveness which forms a strategic link that benefits the manufacturing organizations. The study aims to investigate the relationship among constructs that leads to operational excellence while deploying LSS and sustainable manufacturing strategies in organizations.FindingsEmpirical data needed for the study are collected from experts belonging to various industries that are implementing both LSS and sustainable manufacturing practices. Later statistical estimates (hypotheses) are being formulated to confirm the developed measurement model. Based on the obtained results after analysis of the structural model, the statistical estimate is either being accepted or rejected. Results of this study reveal that there exists a strong correlation between LSS and sustainable manufacturing factors that leads to organizational performance.Research limitations/implicationsAdditional indicators could be included to deal with technological advancements in sustainable manufacturing.Practical implicationsThe study has been done with regard to Indian automotive component manufacturing organizations scenario. Hence, the inferences derived have practical relevance.Originality/valueThe development of structural model for the Lean Six Sigma system with sustainability considerations is the original contribution of the authors.
