An integrated Lean, Green and Six Sigma strategies: A systematic literature review and directions for future research

Abstract

Purpose

The purpose of this paper is to present a systematic literature review and its analysis concerning a possible framework, compatibility, drivers and barriers for integrating three manufacturing strategies – Lean, Green and Six Sigma. In particular, analyzing current proposals and identifying the literature gaps in the existing literature from which future research directions and challenges have been suggested for developing a specific integrated framework for the Indian manufacturing industry.

Design/methodology/approach

This study explores manufacturing strategic area in depth through literature review, which will point out to the better understanding of the compatibility and impact of these initiatives through the conceptual framework, on the performance of the manufacturing organization.

Findings

The review of shortlisted articles indicates that Lean, Green and Six Sigma (LGSS) strategies help the manufacturing organizations to compete in global markets through the impact of a sustainability strategy for their business. Various researchers provide evidence of challenges like cost reduction, quality improvement, on-time delivery, changing needs of the customers and scarce resources that can be overcome through these strategies to achieve overall business objectives.

Research limitations/implications

In this research, only works of literature related to LGSS and sustainability have been studied so information related to linking between these strategies in manufacturing industries is limited.

Practical implications

Help the manufacturing practitioners to deploy three strategies simultaneously in an environment when the linking among LGSS methods in manufacturing industries has not been established. Hence simultaneous deployment of these three strategies helps the organization to boost its operational and environmental performance.

Social implications

The strategies, LGSS, will be adopted in the operational management to reduce both waste and pollution which will definitely help to society. It will highlight the need for cost effective and easy to implement solutions as well as brand building, which is one of the top incentives for LGSS, highlighting the importance of public perception of how companies operate.

Originality/value

An integrated framework of the LGSS will help the Indian manufacturing industries to improve performance and competitiveness in the global market.
