Green Lean Six Sigma sustainability-oriented framework for small and medium enterprises

PurposeThe purpose of this study is to integrate Green technology, Lean and Six Sigma methodology under the umbrella of Green Lean Six Sigma (GLSS). Further, the study also proposes an eight facet GLSS framework for small and medium enterprises (SMEs) to enhance organizational sustainability.Design/methodology/approachIn this study, GLSS integration has been proposed based on intangible features like barriers, challenges, toolsets, etc. Moreover, the GLSS framework has been realized based on Six Sigma well-known define, measure, analyze, improve and control (DMAIC) approach.FindingsIt has been found that lack of customer involvement, financial constraints and ignorance towards Kaizen are the most pre-eminent barriers for GLSS execution. Further, it has been found that most frequently used GLSS tools are the 5S, environmental value stream mapping (EVSM) and life cycle assessment (LCA). The proposed GLSS framework encompasses systematic application of different GLSS tools that lead improved organization sustainability.Practical implicationsThe present study will facilitate industrial managers to incorporate the GLSS approach in their business process through systematic understanding of key elements related to this sustainable approach. This study further prompts practitioner to incorporate GLSS in industry through systematic adoption of the proposed framework for improved environmental performance.Social implicationsThis work provides detailed knowledge for the researchers and academicians by dispensing awareness into integral measures and framework. GLSS toolsets dispensed in this work augments academicians and researchers to make decision which tools to be used at distinct phases of GLSS project execution.Originality/valueThe present study is the first of its kind that provides integral measures and GLSS framework for SMEs.
