Abstract
This paper aims to examine the effects of public sector procurement practices on public sector service delivery in Ghana’s technical universities, while also assessing the influence of institutional leadership and stakeholder pressure as mediating mechanisms within this relationship. In this paper, it is also aimed to evaluate how internal governance conditions shape the effectiveness of procurement reforms in higher education institutions. The study employed the positivist research paradigm, a quantitative research approach and an explanatory research design, using structural equation modelling (SEM) to validate the measurement model and test the structural relationships. Primary data were collected from 235 staff across selected technical universities through a simple random sampling technique using a structured questionnaire. The main findings demonstrate that: (i) procurement practices do not have a significant direct effect on service delivery, indicating that technical interventions alone are insufficient to drive performance improvements; (ii) institutional leadership exerts a strong and positive influence on service delivery, highlighting the importance of strategic direction, governance competence and managerial oversight in shaping public sector outcomes; and finally, (iii) stakeholder pressure substantially enhances service delivery and serves as a critical channel through which procurement practices exert their influence. The results further reveal that both institutional leadership and stakeholder pressure significantly mediate the relationship between procurement practices and service delivery, suggesting that procurement reforms achieve their intended outcomes only when supported by robust institutional environments. These findings provide practical insights for policymakers and higher education managers, emphasising the need for governance-focused interventions alongside procurement reforms to achieve sustainable improvements in service delivery within Ghana’s technical universities.
