A framework for the systematic implementation of Green Lean Six Sigma to improve performance in the manufacturing industry

Green Lean Six Sigma (GLSS) is an all-inclusive methodology that assists the optimal utilisation of resources, minimises waste, and imparts the pathway for sustainable development. This study proposes a novel five facet GLSS framework for the manufacturing industry to improve performance in terms of different sustainability dimensions. The framework has been designed based on three key dimensions: insights from literature, the experience of authors, and inputs from the case organisation members. The framework is validated in an Indian automotive component manufacturing organisation. From the effective implementation of the proposed GLSS framework, defects were minimised from 18,000 ppm to 7,000 ppm and environmental impacts were brought down from 44.70 Pt to 32.70 Pt. This study facilitates industrial managers and practitioners to adopt the GLSS approach to improve sustainability dynamics in the manufacturing industries.
