9. Supply Chain Management  A total system approach to managing the entire flow of information, materials, and services from raw-material suppliers through factories and warehouses to the end user (planning, organizing, directing and controlling flows of materials)  Encompasses all activities associated with the flow and transformation of goods and services from raw materials to the end user, the customer

10. Goals of Supply Chain Management (1 of 2) Synchronization of activities required to achieve maximum competitive benefits Coordination, cooperation, and communication and timing among SC members Ensuring rapid flow of information among members

11. To Accompany Russell and Taylor, Operations Management, 4th Edition,  2003 Prentice-Hall, Inc. All rights reserved. Goals of Supply Chain Management (2 of 2) Linking the market, distribution channels, processes and suppliers so that market demand is met as efficiently as possible across the chain Matching supply and demand at each stage of the chain Ultimate goal: Achieving customer satisfaction

22. Effective Supply Chain Requires linking the market, distribution channels processes, and suppliers

23. Requirements of a Successful Supply Chain  Trust among trading partners  Effective communications Supply chain should enable members to 1) share forecasts, 2) determine the status of orders in real time, 3) access inventory data of partners  Supply chain visibility  Event-management capability  The ability to detect and respond to unplanned events  Measuring SC Performance: Performance metrics

24. Measuring SC Performance: Inventory Turnover One of the most commonly used measures is “Inventory Turnover”

25. Measuring SC Performance: SCOR Metrics PerspectiveMetrics ReliabilityOn-time delivery Order fulfillment lead time Fill rate (fraction of demand met from stock) Perfect order fulfillment FlexibilitySupply chain response time Upside production flexibility ExpensesSupply chain management costs Warranty cost as a percent of revenue Value added per employee Assets/utilizationTotal inventory days of supply Cash-to-cash cycle time Net asset turns

26. Supply Chain Uncertainty Forecasting, lead times, batch ordering, price fluctuations, and inflated orders contribute to variability Inventory is a form of insurance Distorted information is one of the main causes of uncertainty

27. Bullwhip Effect Final Customer Initial Supplier Demand Inventory oscillations become progressively larger moving backward through the supply chain

28. Inventories in a SC: Bullwhip Effect Order Quantity Time Retailer’s Orders Order Quantity Time Wholesaler’s Orders Order Quantity Time Manufacturer’s Orders The magnification of variability in orders in the supply-chain A lot of retailers each with little variability in their orders…. … can lead to greater variability for a fewer number of wholesalers, and… … can lead to even greater variability for a single manufacturer.

49. Sourcing Sourcing is the selection of suppliers Relationship between customers and suppliers focuses on collaboration and cooperation Outsourcing has become a long-term strategic decision Organizations focus on core competencies Single-sourcing is increasingly a part of supplier relations

50. Suppliers Purchased materials account for about half of manufacturing costs Materials, parts, and service must be delivered on time, of high quality, and low cost Suppliers should be integrated into their customers’ supply chains Partnerships should be established On-demand delivery (JIT) is a frequent requirement

51. Evaluating the sources of supply in terms of: Price Quality Flexibility Location Product or service changes Reputation and financial stability Lead times and on-time delivery Inventory policy Services (such as technical support) provided Vendor Analysis

62. Third-Party Logistics The term used to describe the outsourcing of logistics management.

63. Reverse Logistics Reverse logistics – the backward flow of goods returned to the supply chain Processing returned goods – Sorting, examining/testing, restocking, repairing – Reconditioning, recycling, disposing Gatekeeping – screening goods to prevent incorrect acceptance of goods Avoidance – finding ways to minimize the number of items that are returned

64. Distribution Centers and Warehousing Trend is for more frequent orders in smaller quantities Flow-through facilities and automated material handling Final assembly and product configuration may be done at the DC

65. Warehouse Management Systems Highly automated systems Controls item putaway, picking, packing, and shipping Cross-docking: Goods arriving at a warehouse from a supplier are unloaded from the supplier’s truck and loaded onto outbound trucks Avoids warehouse storage

67. Vendor-Managed Inventory Stocking information is accessed using EDI A first step towards supply chain collaboration Increased speed, reduced errors, and improved service

68. Transportation The movement of a product from one location to another as it makes its way to the end-use customer Important element, often overlooked Common methods are railroads, trucking, water, air, intermodal, package carriers, and pipelines

69. Linking the Supply Chain with SAP

70. SC Design System: CPFR Collaborative Planning, Forecasting, and Replenishment  A system based on the notion that there should be cooperation among supply chain partners in planning, coordination of activities and information sharing, which in turn requires partners to agree on common goals (goal sharing)

71. CPFR Process Internet-based exchange of data and information Significant decrease in inventory levels and more efficient logistics Companies focus on core competencies

72. CPFR Results Nabisco and Wegmans – 50% increase in category sales Wal-mart and Sara Lee – 14% reduction in store-level inventory – 32% increase in sales Kimberly-Clark and Kmart – Increased category sales that exceeded market growth

73. Global Supply Chain Problems National and regional differences Customs, business practices, and regulations Foreign markets are not homogeneous Quality can be a major issue

74. Some Issues in Global Supply Chains – Language – Culture – Currency fluctuations – Political – Transportation costs – Local capabilities – Finance and economics – Environmental

75. Infrastructure Obstacles to Global Trade Some emerging markets lack suitable distribution systems, i.e. roads, rail systems Existing roads and ports may be inadequate Market instability, political instability Vertical integration is a common solution

76. 1.Develop strategic objectives and tactics 2.Integrate and coordinate activities in the internal supply chain 3.Coordinate activities with suppliers & with customers 4.Coordinate planning and execution across the supply chain 5.Form strategic partnerships Creating an Effective Supply Chain

77. Supply Chain Performance Drivers 1.Quality 2.Cost 3.Flexibility 4.Velocity 5.Customer service

78. Velocity Inventory velocity – The rate at which inventory(material) goes through the supply chain Information velocity – The rate at which information is communicated in a supply chain

79.  Barriers to integration of organizations  Getting top management on board  Small businesses  Variability and uncertainty  Long lead times  Dealing with trade-offs Challenges to Optimizing SCs

80. 1.Lot-size-inventory 2.Inventory-transportation costs – Cross-docking 3.Lead time-transportation costs 4.Product variety-inventory – Delayed differentiation 5.Cost-customer service – Disintermediation Trade-offs in SCM

81. Techniques to Increase SC Efficiency Delayed differentiation – Production of standard components and subassemblies, which are held until late in the process to add differentiating features Disintermediation – Reducing one or more steps in a supply chain by cutting out one or more intermediaries + Cross Docking + Drop Shipping

82. Potential Solutions to SC Problems ProblemPotential Improvement BenefitsPossible Drawbacks Large inventories Smaller, more frequent deliveries Reduced holding costs Traffic congestion Increased costs Long lead times Delayed differentiation Disintermediation Quick responseMay not be feasible May need absorb functions Large number of parts ModularFewer parts Simpler ordering Less variety Cost Quality OutsourcingReduced cost, higher quality Loss of control VariabilityShorter lead times, better forecasts Able to match supply and demand Less variety

83. 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
