Additionally, this study also determines whether the effect of leadership competency on project performance may be mediated by team commitment. The third objective was to investigate the relationships among the project manager’s leadership competency, team commitment, and project success. To address the primary aims, a questionnaire-based survey was used to measure the project manager’s competency, team commitment, and overall performance of research and development (R&D) projects in the Taiwanese high-tech industry. The analyses suggest that increases in levels of project manager’s leadership competency may enhance commitment among team members. The results also indicate that team commitment exhibits statistically significant influence on project performance. Additionally, the findings suggest that project type has a moderating effect on the relationship between project manager’s leadership competency and project success. Finally, the results indicate that team commitment may serve as mediators between project manager’s leadership competency and project performance.
