Predicting quantity and timing of demand Design Incorporating customer wants, mfg., and time Processing Controlling quality, scheduling work Inventory Meeting demand while managing inventory costs Purchasing
Evaluating suppliers and supporting operations Suppliers Monitoring supplier quality, delivery, and relations Location Determining location of facilities Logistics Deciding how to best move and store materials 11-15 Strategic or Operational
Two types of decisions in supply chain management Strategic design and policy Operational day-today activities Major decisions areas Location Production Inventory Distribution 11-16
Logistics Logistics Refers to the movement of materials and information within a facility and to incoming and outgoing shipments of goods and materials in a supply chain 11-17 Logistics Movement within the facility Incoming and outgoing shipments Bar coding EDI Distribution JIT Deliveries

Extends the concepts of MRPII 11-20 Uses of DRP Management uses DRP to plan and coordinate: Transportation Warehousing Workers Equipment
Financial flows 11-21 E-Business E-Business: the use of electronic technology to facilitate business transactions Applications include Internet buying and selling E-mail Order and shipment tracking
Electronic data interchange 11-22 Advantages E-Business Companies can: Have a global presence Improve competitiveness and quality
Analyze customer interests Collect detailed information Shorten supply chain response times Realize substantial cost savings Create virtual companies Level the playing field for small companies 11-23 Disadvantages of E-Business Customer expectations Order quickly -> fast delivery Order fulfillment Order rate often exceeds ability to fulfill it Inventory holding
Outsourcing loss of control Internal holding costs 11-24 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 11-25
Effective Supply Chain Requires linking the market, distribution channels processes, and suppliers Supply chain should enable members to: Share forecasts Determine the status of orders in real time Access inventory data of partners 11-26 Successful Supply Chain Trust among trading partners Effective communications Supply chain visibility Event-management capability The ability to detect and respond to unplanned events
Performance metrics 11-27 Table 11.4 Perspective SCOR Metrics Metrics Reliability On-time delivery Order fulfillment lead time Fill rate (fraction of demand met from stock) Perfect order fulfillment
Flexibility Supply chain response time Upside production flexibility Expenses Supply chain management costs Warranty cost as a percent of revenue Value added per employee Assets/utilization Total inventory days of supply Cash-to-cash cycle time Net asset turns 11-28
RFID Technology Used to track goods in supply chain RFID tag attached to object Similar to bar codes but uses radio frequency to transmit product information to receiver RFID eliminates need for manual counting and bar code scanning 11-29 CPFR Collaborative Planning, Forecasting, and Replenishment Focuses on information sharing among trading partners Forecasts can be frozen and then
converted into a shipping plan Eliminates typical order processing 11-30 CPFR Process Step 1 Front-end agreement Step 2 Joint business plan Steps 3-5 Sales forecast Steps 6-8 Order forecast collaboration Step 9 Order generation/delivery execution 11-31 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 11-32 Creating an Effective Supply Chain 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 11-33 Supply Chain Performance Drivers 1.Quality 2.Cost 3.Flexibility 4.Velocity 5.Customer service 11-34 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 11-35 Challenges Barriers to integration of organizations Getting top management on board Dealing with trade-offs Small businesses Variability and uncertainty Long lead times 11-36
Trade-offs 1. Lot-size-inventory Bullwhip effect 2. Inventory-transportation costs Cross-docking 3. Lead time-transportation costs 4. Product variety-inventory Delayed differentiation 5. Cost-customer service Disintermediation 11-37 Trade-offs
Bullwhip effect Inventories are progressively larger moving backward through the supply chain Cross-docking Goods arriving at a warehouse from a supplier are unloaded from the suppliers truck and loaded onto outbound trucks Avoids warehouse storage 11-38 Trade-offs 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 11-39 Supply Chain Issues Strategic Issues Design of the supply chain, partnering Tactical Issues Inventory policies
Purchasing policies Production policies Transportation policies Quality policies Operating Issues Quality control Production planning and control 11-40 Supply Chain Benefits and Drawbacks Table 11.5 Problem
Potential Improvement Benefits Possible Drawbacks Large inventories Smaller, more frequent deliveries Reduced holding 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 11-41
Purchasing Purchasing is responsible for obtaining the materials, parts, and supplies and services needed to produce a product or provide a service. Purchasing cycle: Series of steps that begin with a request for purchase and end with notification of shipment received in satisfactory condition. 11-42 Goal of Purchasing Develop and implement purchasing plans for products and services that support operations strategies
