The Mediating Role of Environmental Uncertainty in the Impact of Information Technology on Supply Chain Performance.

In a period in which competition and globalization are increasing day by day, the competition of companies exists among supply chains. To have and sustain competitiveness in the supply chain context, information technologies should be used, supply chain performance should be measured at certain intervals, and environmental uncertainty should be taken into account. In this framework, the purpose of this study is to examine the relationship between information technologies and supply chain performance and to investigate whether environmental uncertainty has a mediating role in this relationship. For this purpose, 192 data points were obtained via a survey obtained from the top 500 international companies active in Turkey and analyzed with SAS software. Resulting from the analysis, it was determined that there is a significant relationship between information technologies, environmental uncertainty, and supply chain performance, and between information technologies and environmental uncertainty. It is concluded that environmental uncertainty has a significant effect on supply chain performance, and information technologies have a significant effect on environmental uncertainty. In addition, it has been determined that information technologies have a significant effect on supply chain performance, and environmental uncertainty has a medi-ating role in this effect. According to the results of this study, managers are suggested to increase their supply chain performance by using information technologies and to consider environmental uncertainty to achieve a sustainable competitive advantage.
