Abstract
PurposeWe examine the relationships among leader spirituality, organizational innovativeness, transformational leadership style and project success. Integrating principles of behavioral learning and social learning theories, we argue that spiritual leadership style is positively linked to project success, and this relationship is mediated by transformational leadership. Furthermore, the relationship between leader spirituality and transformational leadership is moderated by organizational innovativeness.Design/methodology/approachData are collected from 180 individuals working in seven large project-based organizations from the telecom sector in Pakistan. The individuals comprise engineers, functional managers, dedicated project managers and individuals who have led and/or worked in project teams. Data are analyzed using variance-based structural equation modeling.FindingsResults suggest that the relationship between spiritual leadership style and project success is positive and is partially mediated by transformational leadership. Furthermore, organizational innovativeness positively moderates the spiritual leadership and transformational leadership relationship.Originality/valueResearch calls for examining the relationship between leadership styles and project success. We address this call through examining the role of spiritual leadership style (which is rather ignored in project management literature) for project success. Furthermore, we take a novel evolutionary approach of integrating different leadership styles and indicating determinants as well as contingencies to leadership development.
