The increasing complexity in the supply chains (SC) has adverse consequences for businesses. The extant literature is limited in explaining the ways firms in developing economies facing supply chain complexities (SCC), both structural and dynamic, organize themselves to improve firm performance. We adopted SC ambidexterity as a dynamic capability to investigate its influence on the SCC-firm performance. Using empirical data from Pakistan, we employed SEM to evaluate the hypothesis. The outcomes of this study imply that businesses in dynamic settings learn from their experiences and build dynamic capabilities to adapt to the external shocks inherited in complex supply networks.
