Analyzing drivers of sustainable project‐driven supply chains: A fuzzy Delphi methodology–grey relational analysis approach

Abstract

A sustainable project‐driven supply chain (SPDSC) refers to integrating sustainability into project management to improve the sustainability performance of projects. Integrating sustainability and supply chain management is any project‐based organization's most significant performance‐related challenge. Therefore, the present study explores the drivers that can effectively tackle supply chain issues in managing projects undertaken in construction contracting firms for long‐term sustainability. Sixteen critical drivers were considered through a rigorous literature review and fuzzy Delphi method (FDM) for construction contracting firms. Then, selected drivers were used to analyze established construction contracting firms using a grey relational analysis (GRA) technique. The results highlight that construction contracting firms (CCFs) considered the drivers of sustainable use of resources, energy and eco‐efficiency, and environmental impact assessment; stakeholder engagement and social impact; and supply chain collaboration dimensions need to be improved for enhancing the sustainability of PDSCs. This study's contribution is twofold: It quantifies the identified set of critical drivers relevant to SPDSCs; it offers the CCFs a practical toolkit for sustainable project deliverables.
