TRANSFORMATIONAL LEADERSHIP AND MANAGEMENT COMMITMENT IN THE RAILWAY SECTOR: PROCESS MANAGEMENT AS A MEDIATOR OF PRODUCTIVITY IN A DEVELOPING COUNTRY CONTEXTPages 61-76 Abstract
This study examines the relationships between transformational leadership, top leadership commitment, process management and productivity within the Tanzania Zambia Railway Authority (TAZARA). While previous research has predominantly focused on the direct effects of transformational leadership and leadership commitment on organisational outcomes, this study introduces process management as a mediating factor, providing a more comprehensive understanding of how leadership behaviours translate into productivity gains. Using a quantitative approach, data were collected from 157 managers and analysed using Jamovi for regression and mediation analysis. The results show that both transformational leadership and top leadership commitment significantly increase productivity, with process management playing a key mediating role. Transformational leadership promotes productivity by inspiring employees and optimising processes, while top leadership commitment provides strategic direction and resource allocation, which further enhances process efficiency. These findings contribute to the theoretical understanding of leadership dynamics and provide practical insights for organisations seeking to improve productivity through integrated leadership and process management strategies. The study highlights the importance of adopting a synergistic approach that combines transformational leadership, strong top management commitment and effective process management to achieve sustainable organisational success .
Keywords: Transformational Leadership, Top Leadership Commitment, Process Management, Productivity, Mediation Analysis.
