This study examines the role of servant leadership and shared leadership in the performance of new information technology development teams using agile methodologies within an energy company. The research focuses on the impact of the Agile Master s (AM) servant leadership and the shared leadership between the AM and the Technical Leader (TL) on project performance, exploring the mediating roles of team learning and creativity. Data were collected through a survey of approximately 217 members from 71 agile teams (including AMs, TLs, Product Owners, and Developers), alongside institutional performance metrics consolidated by the Scaled Agile Framework (SAFe-trademark). The analysis employed multivariate regression with data from multiple sources. Findings indicate that the AM s servant leadership significantly influences the shared leadership between the AM and TL, and that shared leadership positively affects team learning and creativity. Furthermore, shared leadership and creativity within teams are inversely related to project execution time and positively related to the business value added by the projects. This research contributes to management theory and practice by examining the link between leadership profiles and performance, enhancing the understanding of the connections between leadership and success in IT projects employing agile methodologies.
