What are the strategies to manage megaproject supply chains? A systematic literature review and research agenda

This systematic literature review explores strategies to manage complex supply chains in megaprojects, connecting project management and operations management literatures. A total of 2,106 titles and abstracts were analyzed and 94 papers were fully reviewed, identifying six categories of strategies: inter-firm collaboration and coordination, governance, procurement, projects as networks, production and logistics, and risk management. We present the multi-level Megaproject Supply Chain (MSC) framework, unpacking the complex inter-organizational structure of megaprojects in five levels and units of analysis to guide future research. The MSC framework identifies the micro, meso and macro levels of megaprojects and introduces two additional hybrid levels to identify inter-organizational relationships: the meso‑micro and meso‑macro. We suggest four avenues to advance supply chain management in megaprojects through multi-level explorations: (i) Supply Chain Structure: Permanent vs Temporary, (ii) Strategic Procurement and Commercial, (iii) Supply Chain Design: Standardization vs Customization, (iv) Supply Chain Governance: Collaboration and Coordination.
