A customer is a supplier for some other company. A supplier is a customer for some other company. Not all pieces of a supply chain belongs to the same company.
Notes: Key message here is that logistics costs are a significant fraction of the total value of a product. The problem here is that this a purely cost based view of the supply chain and drives a firm to simply reducing logistics costs. This is an incomplete picture.
Notes: Traditionally logistics and supply chain management have been measured in terms of transportation and inventory costs and the administration required to manage both. Traditionally firms would have an inventory manager and a transportation manager. This view is very narrow and causes significant problems in the proper functioning of the supply chain.
Notes: Supply chain involves everybody, from the customer all the way to the last supplier. Key flows in the supply chain are - information, product, and cash. It is through these flows that a supply chain fills a customer order. The management of these flows is key to the success or failure of a firm. Give Dell & Compaq example, Amazon & Borders example to bring out the fact that all supply chain interaction is through these flows.
The supply chain is a concatenation of cycles with each cycle at the interface of two successive stages in the supply chain. Each cycle involves the customer stage placing an order and receiving it after it has been supplied by the supplier stage. One difference is in size of order. Second difference is in predictability of orders - orders in the procurement cycle are predictable once manufacturing planning has been done. This is the predominant view for ERP systems. It is a transaction level view and clearly defines each process and its owner.
In this view processes are divided based on their timing relative to the timing of a customer order. Define push and pull processes. They key difference is the uncertainty during the two phases. Give examples at Amazon and Borders to illustrate the two views
Dell has three production sites worldwide and builds to order. Compaq does both. Consider some decisions involved - where to locate facilities? How to size them? Where is the push/pull boundary? What modes of transport to use? How much inventory to carry? In what form? Where to source from?

SCM is not strictly a cost reduction paradigm!
