PROCESS AND QUALITY MANAGEMENT PRACTICES AS DRIVERS OF ORGANIZATIONAL PRODUCTIVITY: A QUANTITATIVE MODELING STUDY

This study examines the relationships between top leadership commitment, transformational leadership, process management, education/training and organisational productivity. Using a quantitative approach, data were collected from 162 management level respondents in the Tanzania Zambia Railway Authority (TAZARA) and analysed using Jamovi software. The results show that top leadership commitment has a significant positive effect on productivity, both directly and indirectly. Transformational leadership and education/training, while positively correlated with productivity, do not have significant direct effects. However, process management significantly increases productivity and partially mediates the relationship between leadership commitment and productivity. These findings underscore the critical role of leadership commitment and process optimisation in driving organisational performance, while highlighting the nuanced effects of training and transformational leadership. The study contributes to leadership and management theory by integrating these factors into a single framework, and offers practical insights for organisations seeking to improve productivity through strategic leadership and process management.
