Answer to Question 2
Information systems, such as customer relationship management (CRM) and e-commerce sales systems have dramatically reduced the costs of buying and selling. Sourcing, buying, and selling have all become faster, easier, more effective, and less costly. Distributed systems in the cloud have enabled businesses to integrate their information systems with less cost and greater speed and agility than ever before. The presence of information systems has also expanded supply chain speed. Information systems have enabled both suppliers and customers to reduce the size of their inventories and, thus, reduce their inventory costs. Information systems also improve delivery scheduling. Using information systems, suppliers can deliver materials and components at the time and in the sequence needed. Such delivery enables just-in-time inventory, and it allows manufacturers to reduce raw materials inventory size as well as the handling of raw materials.
