This study investigates the effect of network alliance capabilities and strategic information flow on supply chain viability in the face of supply chain complexity. Using the dynamic capability view, the research shows that complex supply chains encourage firms to develop these capabilities, thus enhancing supply chain viability. The study surveyed 242 supply chain managers in Pakistan and used structural equation modelling to test the hypotheses. The findings add to the existing literature by showing that exposure to supply chain complexity can prompt leading firms to continuously improve their business operations, leading to greater supply chain viability.
