This study explores the impact of “Information Technology Implementation” (IT-Impl) on firms' “Operational Performance” (Op-Per) using the Dynamic Resource-Based View (DRBV), proposing a dynamic influence path including the framework of resources-capability-competitive advantage. The direct effects of IT-Impl on Op-Per have been extensively studied, but not the complex instrumental routes and intermediate processes. This study advances a more sophisticated understanding of the dynamic capabilities in converting IT resources into long-term competitive advantage, particularly identifying the serial mediation of the IT-Impl–Op-Per relationship by supply chain integration (SC-Int) and postponement (Post-P). A quantitative research approach was used to gather data from a sample of 298 top-ranking managers from retail manufacturers to test hypotheses using Smart-PLS. The results show that while IT-Impl positively affects Op-Per through the serial mediating roles, “Information Intensity” negatively moderates these relationships. In practice, Op-Per is influenced by a multitude of factors, including supply chain and internal operating capabilities. The study emphasizes the importance of considering SC-Int and Post-P as dynamic capabilities in leveraging IT-Impl for Op-Per. Organizations should strategically align IT investments with advanced supply chain and internal operating capabilities to gain a sustainable competitive advantage. The results, discussion, contributions, limitations, and potential future directions are provided.

It is commonly assumed that information technology capabilities (ITCs) are instrumental in supply chain viability (SCV), despite negligible empirical evidence. Based on the dynamic resource-based view, this study explores how the SCV competitive advantage is influenced by the heterogeneous resource ITC through the internal operating capability postponement (POST). A quantitative survey was administered to 298 senior managers from retail manufacturing firms, to test hypotheses using hierarchical multiple regression analysis. The SPSS PROCESS Macro was used to determine the mediation and interaction effects of the dual-stage moderated-mediation model, identifying a positive correlation between ITC and POST strategies, highlighting that modern real-time data synchronization and on-demand customization IT systems are needed. POST strategies greatly improve SCV by enhancing operational flexibility, reactivity, and adaptability to dynamic market conditions. The moderators “market orientation” and “demand uncertainty” shape these relationships, emphasizing the need for firms to align their strategies with market dynamics and uncertainties. The research emphasizes the importance of valuable, rare, and inimitable resources in driving sustained competitive advantage. Practical implications suggest strategic investments in advanced IT systems and collaborative efforts in retail manufacturing firms are essential for optimizing supply chain processes. The results, discussion, implications, limitations, and suggestions for additional studies are addressed.
