This document discusses how information technology can be used to manage the supply chain. It begins by explaining how IT enables data and information to flow readily throughout the entire supply chain. Computer-aided decision support systems then use this complex information to enable better and faster decisions. Internally, integrated systems like ERP link different business functions and processes. Externally, inter-organizational systems connect a firm's systems to external entities to share data and integrated processes. The benefits of an integrated supply chain management system include an integrated view of resources, improved channel efficiency, reduced inventory levels and production costs, and enhanced quality.
