Green Lean Six Sigma practice in the industrial and service sectors: from the systematic literature review to an integration diagram

Abstract

Recently, increasing competition pressure and severe environmental situations have posed significant challenges to organizations in the industrial and service sectors. In this context, Green Lean Six Sigma (GLSS) is an important approach for helping industrial and service organizations achieve sustainability. The main objective of this study was to clarify the specific content of GLSS practices in the industrial and service sectors, including frameworks, tools, necessities, barriers, effects, and other aspects, through a systematic literature review (SLR). A statistical analysis was conducted to examine the main characteristics of these GLSS elements and the gaps in their implementation between the two sectors. Based on this analysis, an integration diagram of GLSS key elements is proposed, and it showcases core ideas and processes for implementing GLSS in the industrial and service sectors. The findings demonstrate that GLSS practices bring comprehensive improvements to enterprises in multiple dimensions and exhibit differentiated characteristics in the two sectors. Most GLSS frameworks are primarily designed for the industrial sector, and service organizations have yet to systematically grasp the application of GLSS tools. The findings have reference value for practitioners and researchers in the industrial and service sectors regarding GLSS practices.
