This study aims to examine the indirect impact of supply chain management (SCM) in its three dimensions (relationship with suppliers, relationship with intermediaries and distributors, relationship with customers) on the competitive advantage (CA) in its five dimensions (Cost, Quality, Delivery Time, flexibility, and Creativity commitment) with the presence of information technology (IT) as a mediator. Furthermore, 250 questionnaires were distributed in Halawani Industrial Company. The questionnaires analyzed were 226. The Statistical Package for Social Sciences (SPSS) was used to test the hypotheses. The results of the partial analysis show that both relationships with the suppliers and customers contributed to the impact on IT, while the relationship with intermediaries and distributors did not contribute to the impact, but it was supportive of SCM to indirectly influence CA. The most important result of the study was the necessity to evaluate the fundamental competencies; periodically then continuously in order to alter the imperative assets which are the pillars of core competencies including the requirements and conditions regarding strategic thinking and leadership competencies. Also, the study provides an inventory of knowledge about the reality of SCM and its role in achieving CA through IT, which contributes to enriching the library in overall and Jordanian in specific in this subject.
