Handfield, 2005) Page 8 Department of Business Administration The Supply Chain: Introduction Value Chain versus Supply Chain Value chain – – every step from raw materials to the eventual end user ultimate goal is delivery of maximum value to the end user Supply chain – – activities that get raw materials and subassemblies into manufacturing operation ultimate goal is same as that of value chain Terms are used interchangeably Value: creation of value for customer is important aspect of supply chain management 9 Department of Business Administration Supply Chain Management (SCM) Managing flow of information through supply chain in order to attain the level of synchronization that will make it more responsive to customer needs while lowering costs Keys to effective SCM – information – communication – cooperation – trust 10 Department of Business Administration Supply Chain Management (SCM) Supply Chain Uncertainty and Inventory Inventory – insurance against supply chain uncertainty A major objective of SCM: – respond to uncertainty in customer demand without creating costly excess inventory Factors that contribute to uncertainty – …… 11 Department of Business Administration Supply Chain Management (SCM) Bullwhip Effect Occurs when slight demand variability is magnified as information moves back upstream (Copyright 2011 John Wiley & Sons, Inc.) 12 Department of Business Administration Supply Chain Management (SCM) Effective SCM Keys to effective SCM – Information – Communication – Cooperation – Trust Enablers to effective SCM: - Risk pooling - Information Technology - Supply Chain integration and collaboration 3/12/2012 Page 13 Department of Business Administration Supply Chain Enabler Risk Pooling Risks are aggregated to reduce the impact of individual risks – Combine inventories from multiple locations into one – Reduce parts and product variability, thereby reducing the number of product components – Create flexible capacity 14 Department of Business

Department of Business Administration Supply Chain Enablers Collaborative Planning, Forecasting, and Replenishment (CPFR) • • Two or more companies in a supply chain to synchronize their demand forecasts into a single plan to meet customer demand Parties electronically exchange – past sales trends – point-of-sale data – on-hand inventory – scheduled promotions – forecasts (Bozarth and Handfield, 2005) 24 Department of Business Administration Process Control and SCOR Process Control – not only for manufacturing operations – can be used in any processes of supply chain Supply Chain

Department of Business Administration “Green” Supply Chains • Sustainability • Meeting present needs without compromising the ability of future generations to meet their needs • Sustaining human and social resources • It can be cost effective and profitable • Can provide impetus for product and process innovations • Impulse comes from downstream in the supply chain and moves upstream to suppliers 29 Department of Business Administration “Green” Supply Chains Early success using Green SCM principles Texas Instruments: Saves $8 million each year by reducing its transit packaging budget for its semiconductor business through source reduction, recycling, and use of reusable packaging systems (20% annual savings). Commonwealth Edison: Produced $50 million in financial benefits from managing materials and equipment with a life-cycle management approach. Pepsi-Cola: Saved $44 million by switching from corrugated to reusable plastic shipping containers for one liter and 20ounce bottles conserving 196 million pounds of corrugated material. Dow Corning: Saved $2.3 million by using reconditioned steel drums in 1995. Also conserved 7.8 million pounds of steel. 3/12/2012 (LMI, Supply Chain World Conference, 2005) Page 30 Department of Business Administration Green Supply Chain Potential for cost savings 3/12/2012 (LMI, Supply Chain World Conference, 2005) Page 31 Department of Business Administration Green Supply Chain Classification based on problem context 3/12/2012 Source: Srivastava, S.K.

The collection of people, technology, and systems within an organization that has primary responsibility for providing the organization’s products or services. Supply chain A network of manufacturers and service providers that work together to convert and move goods from the raw materials stage through to the end user. These manufacturers and service providers are linked together through physical flows, information flows, and monetary flows. Operations management The planning, scheduling, and control of the activities that transform inputs into finished goods and services. 3/12/2012 (Bozarth and Handfield, 2005) Page 44 Department of Business Administration Definitions Upstream A term used to describe activities or firms that are positioned earlier in the supply chain relative to some other activity or firm of interest. For example, corn harvesting takes place upstream of cereal processing, while cereal processing takes place upstream of cereal packaging. Downstream A term used of describe activities or firms that are positioned later in the supply chain relative to some other activity or firm of interest. For example, sewing a shirt takes place downstream of weaving the fabric, while weaving the fabric takes place downstream of harvesting the cotton First-tier supplier A supplier that provides products or services directly to a particular firm. 3/12/2012 (Bozarth and Handfield, 2005) Page 45 Department of Business Administration Definitions Second-tier supplier A supplier that provides products or services to a firm’s first-tier supplier. Supply chain management The active management of supply chain activities and relationships in order to maximize customer value and achieve a sustainable competitive advantage. It represents a conscious effort by a firm or group of firms to develop and run supply chains in the most effective and efficient ways possible. Supply-Chain Operations Reference (SCOR) model A framework developed and supported by the Supply-Chain Council that seeks to provide standard descriptions of the processes, relationships, and metrics that define supply chain management. 3/12/2012 (Bozarth and Handfield, 2005) Page 46
