This study investigates the role of Decision Support Systems (DSS) in enhancing electronic supply chain performance within Syriatel, which relies on the Oracle ERP system as an integrated decision-support platform. Although previous studies have examined DSS and ERP impacts on supply chain performance, most were conducted in stable business environments and outside the Syrian context, leaving a clear research gap regarding the effectiveness of DSS dimensions in developing countries operating under economic and operational constraints. This study contributes to the literature by empirically examining how the four DSS dimensions—data management subsystem, model management subsystem, knowledge management subsystem, and user interface system affect electronic supply chain performance in a real-world, resource-constrained environment. A descriptive analytical methodology was adopted, and data were collected through a questionnaire administered to 34 employees in the Supply Chain Management (SCM) and Management Information Systems (MIS) departments. Simple and multiple regression analyses revealed a positive and statistically significant relationship between DSS and electronic supply chain performance. The knowledge management subsystem emerged as the most influential dimension, followed by the user interface system, while data management and model management subsystems showed no statistically significant effects likely due to sample size limitations and functional overlap among DSS components. The study recommends strengthening knowledge management capabilities, improving database updating practices, enhancing user training, and expanding the adoption of integrated ERP systems such as Oracle to improve electronic supply chain performance.
