Harnessing the Supply Chain Attributes in the Contractor Evaluation Matrix: Empirical Analysis of the Influence of Supply Chain Attributes

Abstract

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.
