Supply chain management (SCM) is a management style that focuses on the supply portion of a business with the goal to gain a competitive edge over competition and maximize value and relationships between suppliers and customers. In order to create a sustainable supply chain, there are five important stages that must be involved: Planning, finding sources, making the product, delivering the product, and managing defects or end-of-life’s. Enterprise resource planning (ERP) is a set of process, usually in real-time, used for management purposes. Though these two things can stand alone, they work very well together as well. ERP gives SCM the opportunity to automate  the sources stage and its inventory, the scheduling of the making stage, the scheduling of delivery, and just reduce blocking between suppliers and the business itself. This study provides the relationship between ERP and SCM and identify the benefits and areas of improvement specifically focusing on the effect on competitive edge. My findings show that although ERP does have a positive effect on SCM, decreases cost, improves communication, and gives a competitive edge, it is still proving to be very difficult to implement.
