Supply chain management seeks to enhance competitive performance by closely integrating the internal functions within a company and effectively linking them with the external operations of suppliers and channel members. This study was undertaken to study the impact of supply chain management on overall organizational effectiveness and to identify problems that affect supply chain management success. The results show that organizations generally considered themselves successful at managing their supply chains. However, while they have achieved significant improvement in organizational performance, they have not reached the order of magnitude of improvements ascribed to supply chain management.
