Supply Chain (Definition of) The sequence of organizations- their facilities, functions, processes and activities- that are involved in producing and delivering a product or service Sometimes referred to as value chain Components of Supply (Value) Chains • Supply Component: Starts at the beginning of the SC and ends with the internal operations of the organization. • Demand Component: Starts at the point where the organization’s output is delivered to its immediate customer and ends with the final customer in the chain. Demand chain is the sales and distributon portion of the value chain The length of each component depends on where a particular organization is in the chain The Supply Chain Suppliers Producers Distributors Customers Materials, parts, subassemblies, and services Finished goods, end products and services Package and delivery Total satisfaction with quality, price, delivery, and service Inventory Products and Services Inventory Upstream SC members Products and Services Products and Services Inventory Downstream SC members The Supply Chain Information Suppliers Producers Distributors Customers Materials, parts, subassemblies, and services Finished goods, end products and services Package and delivery Total satisfaction with quality, price, delivery, and service Inventory Products and Services Inventory Products and Services Inventory Products and Services The Supply Chain Information Suppliers Producers Distributors Customers Materials, parts, subassemblies, and services Finished goods, end products and services Package and delivery Total satisfaction with quality, price, delivery, and service Inventory Products and Services Products and Services Inventory Inventory Cash Products and Services The Supply-Chain VISA ® Material Flow Credit Flow Supplier Manufacturer Supplier Schedules Order Flow Retailer Consumer Wholesaler Retailer Cash Flow Flow Management Three types of flow – Product and service flow • Involves movement of goods and services from suppliers to customers as well as handling customer service needs and product returns – Information flow • Involves sharing forecasts and sales data, transmitting orders, tracking shipments, and updating order status – Financial flow • Involves credit terms, payments, and consignment and title ownership arrangements To Accompany Russell and Taylor, Operations Management, 4th Edition, 2003 Prentice-Hall, Inc.

Wholesaler’s Orders Manufacturer’s Orders Time …can lead to greater variability for a fewer number of wholesalers, and… Time …can lead to even greater variability for a single manufacturer. Inventories in a SC: Bullwhip Effect Amount of = inventory Tier 2 Suppliers Tier 1 Suppliers Producer Distributor Retailer Final Customer Mitigating the Bullwhip Effect • Good supply chain management can overcome the bullwhip effect – Strategic buffering • Holding inventory at a distribution center rather than at retail outlets – Replenishment based on need • Vendor-managed inventory – Vendors monitor goods and replenish retail inventories when supplies are low To Accompany Russell and Taylor, Operations Management, 4th Edition, 2003 Prentice-Hall, Inc.

Lot-size-inventory (bullwhip) 2. Inventory-transportation costs – Cross-docking 3. Lead time-transportation costs 4. Product variety-inventory – Delayed differentiation 5. Cost-customer service – Disintermediation Trade-Offs • Lot-size-inventory trade-off – Large lot sizes yield benefits in terms of quantity discounts and lower annual setup costs, but it increases the amount of safety stock (and inventory carrying costs) carried by suppliers • Inventory-transportation costs – Suppliers prefer to ship full truckloads instead of partial loads to spread shipping costs over as many units as possible. This leads to greater holding costs for customers – Cross-docking • A technique whereby goods arriving at a warehouse from a supplier are unloaded from the suppliers truck and loaded onto outbound truck, thereby avoiding warehouse storage To Accompany Russell and Taylor, Operations Management, 4th Edition, 2003 Prentice-Hall, Inc. All rights reserved. Trade-Offs • Lead time-transportation costs – Suppliers like to ship in full loads, but waiting for sufficient orders and/or production to achieve a full load may increase lead time • Product variety-inventory – Greater product variety usually means smaller lot sizes and higher setup costs, as well as higher transportation and inventory management costs – Delayed differentiation (a technique to increase SC efficiency) • Production of standard components and subassemblies which are held until late in the process to add differentiating features To Accompany Russell and Taylor, Operations Management, 4th Edition, 2003 Prentice-Hall, Inc. All rights reserved. Trade-Offs • Cost-customer service – Producing and shipping in large lots reduces costs, but increases lead time – Disintermediation (a technique to increase SC efficiency) • Reducing one or more steps in a supply chain by cutting out one or more intermediaries – Drop Shipping • Shipping directly from the supplier to the end consumer, rather than from the seller, saving both time and reshipping costs To Accompany Russell and Taylor, Operations Management, 4th Edition, 2003 Prentice-Hall, Inc. All rights reserved. Techniques to Increase SC Efficiency To Accompany Russell and Taylor, Operations Management, 4th Edition, 2003 Prentice-Hall, Inc. All rights reserved. Techniques to Increase SC Efficiency • Delayed differentiation Postponing the tasks of differentiating a product for a specific customer until the latest possible point in the supply-chain network. Production of standard components and subassemblies, which are held until late in the process to add differentiating features – Channel assembly (sending distributors the individual components and modules rather than finished goods) • Disintermediation – Reducing one or more steps in a supply chain by cutting out one or more intermediaries + Cross Docking + Drop Shipping Other Techniques to Increase SC Efficiency • Outsourcing • Blanket orders (a long-term purchase commitment to a supplier for items that are to be delivered against short-term releases to ship Drop Shipping and Special Packaging – supplier will ship to end consumer rather than to seller • Vendor managed inventory systems The use of a local supplier to maintain inventory for the manufacturer. • Electronic ordering and funds transfer (paperless ordering, payment by wire) • Internet purchasing (e-procurement) Potential Solutions to SC Problems Problem Potential Improvement Benefits Possible Drawbacks Large inventories Smaller, more frequent Reduced holding deliveries costs Traffic congestion Increased costs Long lead times Delayed differentiation Disintermediation Quick response May not be feasible May need absorb functions Large number of parts Modular Fewer parts Simpler ordering Less variety Cost Quality Outsourcing Reduced cost, higher quality Loss of control Variability Shorter lead times, better forecasts Able to match supply and demand Less variety Critical Issues in SCM • Increased strategic importance • Emphasis on cost, quality,agility and customer service • Technology management • Increased conversion to lean production • Just-in-time deliveries • Few suppliers and vendor integration • Increased outsourcing • Globalization Supply-Chain Performance Compared Administrative costs as percent of purchases Lead time (weeks) Benchmark Typical Firms Firms 3.3% 0.8% 15 8 Time spent in placing order 42 minutes 15 minutes Percentage of late deliveries 33% 2% Percentage of rejected material 1.5% .0001% 400 4 Number of shortages per year To Accompany Russell and Taylor, Operations Management, 4th Edition, 2003 Prentice-Hall, Inc.
