Harnessing the Supply Chain Attributes in the Contractor Evaluation Matrix: Empirical Analysis of the Influence of Supply Chain Attributes
(African Journal of Accounting and Social Science Studies (AJASSS), 2025-06-30) Juma, Hemed
Through a systematic review of the literature, this study identifies a gap in the current evaluation criteria for contractor competence that often overlooks the critical supply chain attributes that influence project success. This study investigated the mediating roles of supply chain commitment, collaboration, and resilience in the relationship between contractor competence and the success of public projects. It posits that successful public projects necessitate not only proficient contractors but also a resilient and cooperative supply chain, especially in the context of disruptions such as those caused by the COVID-19 pandemic. Utilising a quantitative research methodology and data from project stakeholders in Tanzania, this study reveals that while contractor competence is linked to public project success, it is insufficient without the mediating effects of supply chain collaboration and resilience. The findings indicate that supply chain resilience significantly enhances the positive relationship between contractor competence and public project success, whereas supply chain commitment does not exhibit a mediating effect. This study underscores the necessity for public procurement entities to incorporate supply chain dynamics into contractor evaluation criteria to mitigate project delays, cost overruns, and quality issues, thereby fostering improved project outcomes. This study contributes to the discourse on public project management by emphasising the interdependence of contractor competence and supply chain attributes in achieving project success.
