What is wrong with the front-end of infrastructure megaprojects and how to fix it : a systematic literature review

The Front-End process plays an essential role in deriving infrastructure megaprojects' performance. However, Front-End issues often negatively impact the process, hindering the value of infrastructure for society. This paper aims to systemise knowledge and understanding of the Front-End of infrastructure megaprojects, the main Front-End issues, and remedies for managing them. The paper leverages a Systematic Literature Review to address four research questions: What definition can appropriately describe the Front-End of infrastructure megaprojects? What are the issues at the Front-End of infrastructure megaprojects? What are the remedies for managing the issues at the Front-End of infrastructure megaprojects? What are the connections between Front-End issues and the remedies for managing them? Following thematic analysis, iterative coding and group discussions, the paper develops a definition for the Front-End of infrastructure megaprojects based on five characteristics, identifies 44 Front-End issues, and connects these issues to six remedies through 17 links.
