Define supply chain management. Compare and contrast the traditional adversarial approach to suppliers and customers with the supply chain management approach discussed in the text and lectures and demonstrated in simulations and case studies. What are the value chain benefits of supply chain management in contrast to adversarial relationships? Be specific with regard to these benefits. What costs are reduced and for whom? How are costs reduced? How is customer service improved? For what a customer is it improved? How is value created through supply chain management?
