This study investigates the critical role of IT infrastructure and project flexibility in achieving project success within the financial sector. Based on resource-based theory and the dynamic capabilities perspective, we propose a conceptual model wherein IT infrastructure influences project success both directly and indirectly through its impact on project flexibility. Data collected from 190 financial sector professionals were analyzed using PLS-SEM. Our findings provide strong support for all hypothesized relationships. Specifically, we find that IT infrastructure has a significant positive impact on both project success and project flexibility. Furthermore, project flexibility is found to mediate the relationship between IT infrastructure and project success, indicating that a robust IT infrastructure contributes to project success, in part, by fostering greater project flexibility. These findings indicate the strategic importance of IT infrastructure investments for financial institutions seeking to enhance project outcomes in a rapidly changing and increasingly competitive landscape.

This study investigates the impact of different leadership styles on project success, specifically examining the mediating role of team collaboration. This study utilized a diverse sample of 202 respondents representing five distinct national contexts: Jordan, Saudi Arabia, China, Australia, and the United Arab Emirates. PLS-SEM were employed to analyze the relationships between transformational leadership, transactional leadership, laissez-faire leadership, team collaboration, and project success. Our findings reveal that both transformational and transactional leadership styles are positively associated with project success. Conversely, laissez-faire leadership demonstrated a negative relationship with team collaboration but did not directly predict project success. Importantly, team collaboration was found to mediate the relationship between both transformational leadership and project success, as well as between transactional leadership and project success. However, the hypothesized mediating role of team collaboration between laissez-faire leadership and project success was not supported. These findings underscore the critical role of leadership style and team collaboration in achieving project success, offering valuable insights for organizations and project managers seeking to optimize leadership practices and foster collaborative work environments.
