Validation of a model measuring the effect of a project manager's leadership style on project performance

This study validates a model for assessing the relationships among a project manager's leadership style, teamwork, project performance, and stakeholder satisfaction. It determines whether the effect of leadership style on project performance can be mediated by teamwork. An industry-wide survey measured a project manager's leadership style, teamwork, and project outcomes in project performance and stakeholder satisfaction. Structural Equation Modeling (SEM) approach confirmed this research model. Analyses show that a project manager who adopts transactional and transformational leadership can improve teamwork and capital facility project performance. Additionally, stakeholder satisfaction can be achieved with high levels of project success in schedule, cost, and quality performance. These findings show that teamwork can partially mediate relationships between leadership style and project performance.
