The Role of Strategic Alignment and Government Support in Driving Sustainable Project Success - Indonesia's Infrastructure Project Case

Purpose: Project management plays a critical role in ensuring the success of complex initiatives, particularly in sectors like infrastructure projects, including in Indonesia. Despite its importance, managing projects remains a persistent challenges that go beyond the traditional project management constraints of time, cost, and quality and increasingly demands attention to broader social and environmental sustainability considerations. This study aims to investigate the relationship between strategic alignment in sustainable project management and sustainable project success, as well as the moderating role of government support. Design/methodology/approach: The quantitative study employs purposive sampling, involving 133 project managers from Indonesia's infrastructure sector as respondents. The Partial Least Squares Structural Equation Modelling(PLS-SEM) technique assessed the hypotheses. Findings: This study demonstrates that strategic alignment directly influences sustainable project management and project success. On the other hand, while impacting the project's success, government support does not play the moderating role between sustainable project management and sustainable project success. Research limitations/implications: This study contributes to the understanding of sustainable project management and its influencing factors towards sustainable project success and provides practical implications for infrastructure projects and their stakeholders. Originality/value: This research provides empirical evidence to validate the growing body of knowledge on sustainable project management and enhances the Triple Bottom Line theory at the project level.
