Public-Private Partnership (PPP) is one of the engaging words found in the recent public sector management and governance literature since 1990’s. Interestingly, literature on PPP policy implementation performance evaluation are still evolving. Against the presence of several methods for evaluating PPP performance and inclusion of diverse range of criteria, this study gives particular focus on evaluating PPP policy implementation performance based on a theory driven approach. Considering network management perspective as basic theoretical framework, this study evaluates PPP performance of two land port PPPs in Bangladesh using case study procedures and qualitative comparative analysis (QCA) techniques. The study reveals that QCA is capable of indicating PPP success in more precise form based on qualitative remark scale. The basic advantage of the theory driven evaluation approach is reflected in surfacing up the strength of various performance indicators, which offer more insights in describing differences in PPP performance.
