Gaps in megaproject management system literature: a systematic overview

Purpose This paper aims to present a structured and comprehensive review of relevant works, collected through a systematic methodology and clustered into nine meaningful categories on megaproject management systems and the current requirements for improved industrial megaprojects. Design/methodology/approach The methodology employed in this paper retrieves relevant works from available online citation indexes that are published in peer-reviewed journals and other reliable sources from 2000 to 2021. Findings It has been observed that the literature on megaproject management is still premature and requires further research to understand better the main gaps and effects of large-scale and typically complex megaprojects. Significant improvements are needed towards covering gaps to address the project management system holistically over the entire project life cycle. There are no clear guidelines for achieving a complete and conclusive project management system and enhancing future megaprojects' management capabilities. Originality/value This paper provides a clear picture of the existing literature on megaproject management systems, contributing insights for successful megaproject projects. Additionally, the holistic analysis identifies gaps in the body of knowledge, revealing avenues for future research.
