Mapping Green, Lean, Six Sigma enablers through the lens of a construction sector: an emerging economy's perspective

Resource conservation, sustainability, quality, and cost control have been considered significant issues for the construction sector worldwide. Green Lean Six Sigma not only improves quality, process flow, resource conservation, and environmental performance but also minimizes cost, waste, and lead time. The construction sector in Pakistan is struggling to adopt sustainable and quality-oriented practices. In this context, this paper aims to identify Green Lean Six Sigma enablers from the perspective of Pakistan's construction industry. Interpretive Structural Modelling consolidated with the Fuzzy Matrice d'Impacts Croises - Multipication Applique a classement technique, was employed to establish an ISM model and measure fuzzy indirect interactions, strengths, effectiveness and categorization of enablers. The findings signify that the most significant driving enablers are government support and incentives, availability of financial resources, top-management determination to enhance sustainability, and organizational capability and quality maturity level for GLS operations. These results could facilitate practitioners, policymakers, and government by providing insights to promote GLS methods for the sustainable growth of the construction sector. This study will assist practitioners and policymakers in developing appropriate strategies considering the intricate relationships and intensity of influence among Green, Lean and Six Sigma enablers during GLS adoption. Researchers can identify and analyze the elements related to their industries and country. Society will benefit in terms of health and the environmentally friendly built environment.
