11. © 2007 Pearson Education Inventory Measures of Supply Chain Performance  Average aggregate inventory value (AGV) is the total value of all items held in inventory for a firm. AGV = (# of A items)(Value of each A)+(# of B items)(Value of each B)+…  Weeks of supply: The average aggregate inventory value divided by sales per week at cost. Weeks of supply = Average aggregate inventory value Weekly sales (at cost)  Inventory turnover is annual sales at cost divided by the average aggregate inventory value maintained for the year. Inventory turnover = Annual sales at (cost) Average aggregate inventory value

14. © 2007 Pearson Education Links to Financial Measures  Return on Assets (ROA): is net income divided by total assets.  Managing the supply chain so as to reduce the aggregate inventory investment will reduce the total assets portion of the firm’s balance sheet.  Working Capital: Money used to finance ongoing operations.  Weeks of inventory and inventory turns are reflected in working capital.  Decreasing weeks of supply or increasing inventory turns reduces the working capital.

15. © 2007 Pearson Education Links to Financial Measures  Cost of Goods Sold: Buying materials at a better price, or transforming them more efficiently, improves a firm’s cost of goods sold measure and ultimately its net income.  Total Revenue: Increasing the percent of on-time deliveries to customers increases total revenue because satisfied customers will buy more services and products.  Cash Flow: Cash-to-cash is the time lag between paying for the services and materials needed to produce a service or product and receiving payment for it.  The shorter the time lag, the better the cash flow position of the firm because it needs less working capital.

16. © 2007 Pearson Education Supply Chain Dynamics  Supply chain dynamics can wreak havoc on supply chain performance measures.  Actions of downstream supply chain members can affect the operations of upstream members.  The bullwhip effect: The phenomenon in supply chains whereby ordering patterns experience increasing variance as you proceed upstream in the chain.

17. © 2007 Pearson Education Supply Chain Dynamics for Facial Tissue Quantity ordered Time Bullwhip Effect

18. © 2007 Pearson Education External Causes of Supply Chain Disruption  Volume changes.  Customers may change ordered quantity or delivery date.  Service and product mix changes.  Customers may change the mix of ordered items.  Late deliveries.  Late deliveries can force a switch in production schedules.  Underfilled shipments.  Partial shipments can cause a switch in production schedule or quantity produced.

19. © 2007 Pearson Education Internal Causes of Supply Chain Disruption  Internally generated shortages of parts.  Engineering changes to the design of services or products are disruptive.  New service or product introductions disrupt the supply chain and may require a new supply chain.  Service or product promotions may create a demand spike.  Information errors such as demand forecast errors, faulty inventory counts, or miscommunication with suppliers.

20. © 2007 Pearson Education The Customer Relationship Process  Electronic Commerce (e-commerce) is the application of information and communication technology anywhere along the value chain of business processes.  Business-to-Consumer Systems (B2C) allows customers to transact business over the Internet.  Business-to-Business Systems (B2B) involves commerce between firms.  The biggest growth area, it is currently about 70% of the regular economy. E-Commerce and the Marketing Process

21. © 2007 Pearson Education E-Commerce and the Order Placement Process  Cost reduction: Using the Internet can reduce the costs of processing orders.  Revenue flow increase: Reduction in the time lag associated with billing the customer or waiting for checks.  Global Access: Available 24 hours a day.  Price flexibility: Prices can easily be changed as the need arises. The Customer Relationship Process

22. © 2007 Pearson Education Order Fulfillment at Dell, Inc. 1.Customers buy from Dell by web site, voice-to-voice, and face-to-face. 2.Order information is transmitted to the inventory system. 3.Unique product configuration information is contained in the Traveler, a sheet that travels with the system the customer has ordered throughout its assembly and shipping. 4.When the Traveler is pulled, all required internal parts and components for a system are picked and put in a tote or kit. (Procedure is called Kitting) 5.A team uses the kit to assemble and initially test the system. 6.Systems are thoroughly tested. 7.Completed systems are boxed and placed on trucks. 8.The entire assemble-to-order cycle takes only a few hours.

24. © 2007 Pearson Education The Order Fulfillment Process  Centralized placement: Keeping all the inventory at one location such as a firm’s manufacturing plant or a warehouse and shipping directly to customers.  Inventory pooling is a reduction in inventory and safety stock because of the merging of variable demands from customers.  A higher than expected demand from one customer can be offset by a lower-than-expected demand from another.  Forward placement is locating stock closer to customers at a warehouse, wholesaler, or retailer. Inventory Placement

25. © 2007 Pearson Education The Order Fulfillment Process  Vendor-managed inventories (VMI): An extreme application of forward placement involving locating inventories at the customer’s facilities.  Key ingredients are:  Collaborative effort requires trust & accountability.  Cost savings is realized by eliminating excess inventory.  Customer service: The supplier is frequently on site for improved response times and reducing stockouts.  Written agreement on procedures, methods, and schedules are clearly specified. Vendor-Managed Inventories

26. © 2007 Pearson Education Order Fulfillment Programs  Continuous Replenishment Program (CRP) A VMI method in which the supplier monitors the customer’s inventory levels and replenishes stock as needed.  Collaborative planning, forecasting, and replenishment ( CPFR )  Radio Frequency Identification (RFID) A method for identifying items through the use of radio signals from a tag attached to an item.  Wal-Mart and Gillette are among a number of large retailers, manufacturers, government agencies, and suppliers currently implementing RFID in their supply chains.

27. © 2007 Pearson Education Distribution Processes  Ownership: Rather than negotiate with a contract carrier, a firm has the most control over the distribution process if it owns and operates it, thereby becoming a private carrier.  Firms may use a combination of the five basic modes of transportation: truck, train, ship, pipeline, and airplane.  Cross-Docking: The packing of products on incoming shipments so that they can be easily sorted at intermediate warehouses for outgoing shipments based on their final destinations.  Items are carried from the incoming-vehicle docking point to the outgoing-vehicle docking point without being stored in inventory at the warehouse.

28. © 2007 Pearson Education Continuous Replenishment at  Each morning Campbell uses Electronic Data Interchange to link with retailers.  Retailers inform Campbell of demands for its products and the current inventory levels in their distribution centers.  Campbell determines which products need replenishment based on upper and lower inventory limits established with each retailer.  Campbell makes daily deliveries of needed products.

29. © 2007 Pearson Education The Supplier Relationship Process  The sourcing process qualifies, selects, manages the contracts, and evaluates suppliers.  The design collaboration process focuses on jointly designing new services or products with key suppliers, seeking to eliminate costly delays and mistakes incurred when many suppliers concurrently, but independently, design service packages or manufactured components.  The negotiation process focuses on obtaining an effective contract that meets the price, quality, and delivery requirements of the supplier relationship process’s internal customers.

30. © 2007 Pearson Education  The buying process relates to the actual procurement of the service or material from the supplier. This process includes the creation, management, and approval of purchase orders.  The information exchange process facilitates the exchange of pertinent operating information, such as forecasts, schedules, and inventory levels between the firm and its supplier. The Supplier Relationship Process

31. © 2007 Pearson Education Supplier Selection and Certification  Purchasing: The activity that decides which suppliers to use, negotiates contracts, and determines whether to buy locally.  Supplier selection often considers the criteria of price, quality and delivery.  Green purchasing: The process of identifying, assessing, and managing the flow of environmental waste and finding ways to reduce it and minimize its impact on the environment.  Supplier certification programs verify that potential suppliers have the capability to provide the services or materials the buyer firm requires.

32. © 2007 Pearson Education Supplier Relations  Competitive orientation views negotiations between buyer and seller as a zero-sum game. Whatever one side loses, the other side gains, and short-term advantages are prized over long-term commitments.  Cooperative orientation is where the buyer and seller are partners, each helping the other as much as possible.  Sole sourcing is the awarding of a contract for a service or item to only one supplier.

33. © 2007 Pearson Education Electronic Purchasing  Electronic Data Interchange (EDI) enables the transmission of routine, standardized business documents from computer to computer.  Catalog hubs: A system whereby suppliers post their catalog of items on the Internet and buyers select what they need and purchase them electronically.  Exchange: An electronic marketplace where buying firms and selling firms come together to do business.  Auction: A marketplace where firms place competitive bids to buy something.

34. © 2007 Pearson Education Centralized versus Localized Buying  Centralized buying increases purchasing clout. Savings can be significant, often 10% or more.  Increased buying power can mean getting better service, ensuring long-term supply availability, or developing new supplier capability.  The biggest disadvantage is loss of local control.  Centralized buying is undesirable for items unique to a particular facility.  The best solution may be one where both local autonomy and centralized buying are possible.

35. © 2007 Pearson Education Supply Chain Strategies  Efficient supply chains focus on the efficient flows of services and materials, keeping inventories to a minimum.  Work best where demand is highly predictable.  Responsive supply chains are designed to react quickly.  Work best when firms offer a great variety of services or products and demand predictability is low.

37. © 2007 Pearson Education Outsourcing  A Make-or-buy decision is a managerial choice between whether to outsource a process or do it in-house.  Outsourcing: Paying suppliers and distributors to perform processes and provide needed services and materials.  Backward integration is a firm’s movement upstream toward the sources of raw materials, parts, and services through acquisitions.  Forward integration is acquiring more channels of distribution, such as distribution centers (warehouses) and retail stores, or even business customers.

38. © 2007 Pearson Education Offshoring  Offshoring is a supply chain strategy that involves moving processes to another country. Factors that influence the offshoring decision include:  Pitfalls of offshoring include:  Pulling the plug too quickly. Not making a good-faith effort to fix the existing process  Technology transfer  Difficulties integrating processes  Tariffs and Taxes  Internet  Comparative labor costs  Logistics costs  Labor Laws and Unions
