Benefits of Effective Supply Chain Management Organization Benefit Campbell Soup Doubled inventory turnover rate Hewlett-Packard Cut supply costs 75% Samsung Reduce inventory buffer from 21 to 15 days Wal-Mart Largest and most profitable retailer in the world

Benefits of Supply Chain Management Lower inventories Higher productivity Greater agility Shorter lead times Higher profits Greater customer loyalty Integrates separate organizations into a cohesive operating system

Elements of Supply Chain Management Table 11.1 Deciding how to best move and store materials Logistics Determining location of facilities Location Monitoring supplier quality, delivery, and relations Suppliers Evaluating suppliers and supporting operations Purchasing Meeting demand while managing inventory costs Inventory Controlling quality, scheduling work Processing Incorporating customer wants, manufacturing, and time Design Predicting quantity and timing of demand Forecasting Determining what customers want Customers Typical Issues Element

Strategic or Operational Two types of decisions in supply chain management Strategic: design and policy Operational: day-to-day activities Major decisions areas Location Production Inventory Distribution

Logistics Logistics Refers to movement of materials, services, cash and information in a supply chain Movement within the facility Incoming and outgoing shipments Distribution Requirements Planning (DRP) Third Party Logistics (3PLs) Reverse Logistics 214800 232087768

Distribution Requirements Planning Distribution requirements planning (DRP) is a system for inventory management and distribution planning Extends the concepts of MRPII

Uses of DRP Management uses DRP to plan and coordinate: Transportation Warehousing Workers Equipment Financial flows

Reverse Logistics Reverse logistics: the backward flow of goods returned to the supply chain from their final destination 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

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

Advantages of 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

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

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

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

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

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

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

Creating an Effective Supply Chain Develop strategic objectives and tactics Integrate and coordinate activities in the internal supply chain Coordinate activities with suppliers and customers Coordinate planning and execution across the supply chain Form strategic partnerships

Supply Chain Performance Drivers Quality Cost Flexibility Velocity Customer service

Velocity Inventory velocity Information 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

Challenges Barriers to integration of organizations Getting top management on board Dealing with trade-offs Small businesses Variability and uncertainty Response time

Trade-Offs Lot-size-inventory Inventory-transportation costs Bullwhip effect Inventory-transportation costs Cross-docking Lead time-transportation costs Product variety-inventory Delayed differentiation Cost-customer service Disintermediation

Trade-Offs Bullwhip effect Cross-docking Inventories are progressively larger moving backward through the supply chain 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

Trade-Offs Delayed differentiation Disintermediation 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

Supply Chain Issues Operating Issues Tactical Issues Strategic Issues Quality control Production planning and control Inventory policies Purchasing policies Production policies Transportation policies Quality policies Design of the supply chain, partnering Operating Issues Tactical Issues Strategic Issues

Supply Chain Benefits and Drawbacks Table 11.4 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 to 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

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 begins with a request for purchase and ends with notification of shipment received in satisfactory condition.

Goal of Purchasing Develop and implement purchasing plans for products and services that support operations strategies

Duties/Roles of Purchasing Identifying sources of supply Negotiating contracts Maintaining a database of suppliers Obtaining goods and services Managing supplies

Factors in Choosing a Supplier Quality and quality assurance Flexibility Location Price

Factors in Choosing a Supplier Product or service changes Reputation and financial stability Lead times and on-time delivery Other accounts

Evaluating Sources of Supply Vendor analysis: Evaluating the sources of supply in terms of price, quality, reputation, and service

Suppliers: Adversary vs. Partner Table 11.7 Aspect Adversary Partner Number of suppliers Many One or a few Length of relationship May be brief Long-term Low price Major consideration Moderately important Reliability May not be high High Openness Low Quality May be unreliable; buyer inspects At the source; vendor certified Volume of business May be low Flexibility Relatively low Relatively high Location Widely dispersed Nearness is important

Supplier Partnerships Ideas from suppliers could lead to improved competitiveness Reduce cost of making the purchase Reduce transportation costs Reduce production costs Improve product quality Improve product design Reduce time to market Improve customer satisfaction Reduce inventory costs Introduce new products or services
