Firms use intranets to improve coordination among their internal supply chain processes, and they can use extranets to coordinate supply chain processes shared with their business partners. Using intranets and extranets (both based on Internet technology), all members of the supply chain can instantly communicate with each other, using up-to-date information to adjust purchasing, logistics, manufacturing, packaging, and schedules. A manager can use a Web interface to tap into suppliers’ systems to determine whether inventory and production capabilities match demand for the firm’s products. Business partners can use Web-based supply chain management tools to collaborate online with suppliers and customers. Sales representatives can access suppliers’ production schedules and logistics information to monitor customers’ order status. The Internet has introduced new ways of managing warehousing, shipping, and packaging based on access to supply chain information that can give companies an edge in delivering goods and services at a reasonable cost.
