The Impact of Project Managers' Personality on Project Success in NGOs: The Mediating Role of Transformational Leadership

This study examined the extent to which project managers' personality determines project success through the mediating mechanism of transformational leadership. The context of the study was nongovernmental projects that focused on education and health. Data were collected from 170 project managers who were engaged in 10 different programs in various areas of Pakistan. Based on the post-positivism approach and a specific deductive design, the results of the study indicated that Extraversion, Agreeableness, and Openness to Experience were direct positive predictors of project success, whereas transformational leadership acted as a mediator of these relations. One of the personality dimensions (i.e., Conscientiousness) had only an indirect effect on project success through transformational leadership. No relation was found between Neuroticism and project success. The theoretical and practical implications for project management are also discussed.
