Transformational Leadership and Job Task Effectiveness: A Systematic Review and Conceptual Model Integrating Core Job Characteristics and Job Crafting

Abstract

This systematic review examines the relationship between transformational leadership and job task effectiveness, emphasizing the mediating roles of core job characteristics and job crafting. Analyzing 80 studies from databases like Scopus and ProQuest, the review identifies key themes and gaps in existing research. Findings reveal that transformational leadership enhances core job characteristics—skill variety, task identity, task significance, autonomy, and feedback—positively influencing job task effectiveness. Job crafting further mediates this relationship by allowing employees to reshape their roles to align with their strengths. The study provides practical insights for organizations, advocating for leadership strategies that enhance job characteristics and encourage job crafting to improve employee performance. By integrating these elements into a conceptual model, this research offers a holistic approach to optimizing job task effectiveness.
