Drawing on leadership theory, this research verified what makes shared leadership an effective form of leadership for agile project teams, and whether using it influences the outcomes achieved by such teams as well as the more distal outcomes. Survey data were collected from 251 members of agile project teams implementing projects of an iterative and incremental character. Structural equation modeling (PLS-SEM) was adopted to test the hypotheses. Our research confirms that shared leadership is an effective form of leadership for agile project teams whose members are empowered to engage in leadership functions or processes. The findings confirm a positive direct impact of shared leadership on the performance of agile project teams and indirect impact on project efficiency and effectiveness. The research results also confirm the influence of project team–related contextual moderators on shared leadership inputs and outputs. The study contributes to leadership theory in the plural leadership research stream and confirms the shift from individual leadership to collective leadership as a result of the growing popularity of the agility paradigm.
