  3. 3. SUPPLY CHAIN MANAGEMENT Also referred to as the logistics network Suppliers, manufacturers, warehouses, distribution centers and retail outlets – “facilities”and the Raw materials Work-in-process (WIP) inventory Finished productsthat flow between the facilities.Hence SCM is a network of all parties involved, either directly (or) indirectly, in fulfilling a customer request.
  4. 4. Supply Chain includes Material flows Information flows Financial flowsLOGISTICS Physical Distribution Management(1976) Logistics is the process of planning, implementing, controlling efficient and effective flow and storage of goods, services and related information from the point of origin to the point of consumption.

  7. 7. HISTORY OF SUPPLY CHAIN MANAGEMENT  1960’s - Inventory Management Focus, Cost Control  1970’s - MRP & BOM - Operations Planning  1980’s - MRPII, JIT - Materials Management, Logistics  1990’s - SCM - ERP - “Integrated” Purchasing, Financials, Manufacturing, Order Entry  2000’s - Optimized “Value Network” with Real- Time Decision Support; Synchronized & Collaborative Extended Network 7
  8. 8. Supply Chain objectives To have the right products in the right quantities at the right place at the right moment at minimal cost. It is characterized by a sharp focus on  Maximize the overall profit  Better asset utilization  Cost reduction.
  9. 9. Importance of SC Reduced inventories along the chain. Better information sharing among the partners. Planning being done in consultation rather than in isolation. Supply chain design, planning and operation decisions play a significant role in the success or failure of the firmMeasuring Factors of SCM Responsiveness Efficiency 9

  11. 11. DECISION PHASES IN SC Developing Strategy / Design Planning Supply Chain Supply Chain Operation 11
  12. 12. Decisons in Developing a strategy or Design: What is the chain’s configuration? How resources will be allocated? What process each stages will perform? Whether to outsource or perform in/house?
  13. 13. Decisions in Planning Supply Chain: Forecasting the demand for the coming year Which markets will be supplied from which locations? The inventory policies to be followed The timing and size of marketing and size of marketing and pricing promotions
  14. 14. Steps in Supply Chain Operations: Set delivery schedules of trucks and placing orders Set a date that the order to be filled. Generate pick lists at a warehouse Allocate a particular order to particular shipping mode or shipment Allocate inventory or production to individual orders.
  15. 15. PROCESS VIEWS Cycle view Push/pull view Cycle View: The process is divided into a series of cycles, each performed at the interface between two successive stages of a supply chain. Push/Pull view: The process in supply chain are divided into two categories depending on whether they are executedin response to the consumer order or in anticipation of the customer orders. 15
  16. 16. Cycle View:• Given the fivestages of supply chain :• Customer Customer order cycle• Retailer Replenishment Cycle• Distributor Manufacturing• Manufacturer cycle Procurement• Supplier Cycle
  17. 17. Sub Process in each cycle: Supplier markets Supplier receives product Buyer places order orderBuyer reverse flows to supplier or third Buyer receives Supplier supplies party supply order
  18. 18. PUSH STRATEGIES  Classical manufacturing supply chain strategy  Manufacturing forecasts are long-range  Orders from retailers’ warehouses  Longer response time to react to marketplace changes  Unable to meet changing demand patterns  Supply chain inventory becomes obsolete as demand for certain products disappears  Increased variability (Bullwhip effect) leading to:  Large inventory safety stocks  Larger and more variably sized production batches  Unacceptable service levels  Inventory obsolescence  Inefficient use of production facilities (factories)  How is demand determined? Peak? Average?  How is transportation capacity determined?  Examples: Auto industry, large appliances, others? 18
  19. 19. PULL STRATEGIES  Demand-driven  Coordinated with true customer demand  None or little inventory held  Only in response to specific orders  Decreased lead times  Decreased retailer inventory  Decreased variability in the supply chain and especially at manufacturers  Decreased manufacturer inventory  More efficient use of resources  More difficult to take advantage of scale opportunities  Examples: Dell, Amazon 19
  20. 20. PUSH/PULL STRATEGIES  Hybrid of “push” and “pull” strategies to overcome disadvantages of each  Early stages of product assembly are done in a “push” manner  Partial assembly of product based on aggregate demand forecasts (which are more accurate than individual product demand forecasts)  Uncertainty is reduced so safety stock inventory is lower  Final product assembly is done based on customer demand for specific product configurations  Supply chain timeline determines “push-pull boundary” Push- Pull Boundary “Generic” Product “Customized” Product Push Strategy Pull Strategy Raw EndMaterials Consumer Supply Chain Timeline 20

  24. 24. SUPPLY CHAIN MANAGEMENT – KEY ISSUES  Overcoming functional silos with conflicting goals Customer Service/ Purchasing Manufacturing Distribution Sales Low pur- Few change- chase price overs High service Low levels Multiple Stable inventories schedules Low costs vendors Low transportation costs SOURCE MAKE DELIVER SELL 24
  25. 25. SUPPLY CHAIN MANAGEMENT – KEYISSUES ISSUE CONSIDERATIONSNetwork Planning • Warehouse locations and capacities • Plant locations and production levels • Transportation flows between facilities to minimize cost and timeInventory Control • How should inventory be managed? • Why does inventory fluctuate and what strategies minimize this?Supply Contracts • Impact of Revenue sharing • Pricing strategiesStrategic Partnering • What information and processes can be shared? • What partnerships should be implemented and in which situations?Outsourcing & Procurement • What are our core supply chain capabilities and which are not?Strategies • Does our product design mandate different outsourcing approaches? • Risk managementProduct Design • How are inventory holding and transportation costs affected by product design? • How does product design enable mass customization? 25
  26. 26. BULL WHIP EFFECT  Inventory and back-order levels fluctuate considerably across the supply chain even when customer demand doesn’t vary  The variability worsens as we travel “up” the supply chain  Forecasting doesn’t help Multi-tier Wholesale Suppliers Manufacturer Distributors Retailers Consumers Sales Sales Sales Sales Time Time Time Time Bullwhip Effect 26
  27. 27. FACTORS CONTRIBUTING TO THEBULLWHIP  Demand forecasting practices  Min-max inventory management (reorder points to bring inventory up to predicted levels)  Lead time  Longer lead times lead to greater variability in estimates of average demand, thus increasing variability and safety stock costs  Batch ordering  Fixed ordering costs  Impact of transportation costs (e.g., fuel costs)  Sales quotas  Price fluctuations  Promotion and discount policies  Lack of centralized information 27
  28. 28. TAMING THE BULLWHIP Four critical methods for reducing the Bullwhip effect:  Reduce uncertainty in the supply chain  Centralize demand information  Keep each stage of the supply chain provided with up-to- date customer demand information  More frequent planning (continuous real-time planning the goal)  Reduce variability in the supply chain  Every-day-low-price strategies for stable demand patterns  Eliminate the bullwhip through strategic partnerships  Vendor-managed inventory (VMI)  Collaborative planning, forecasting and replenishment (CPFR) 28
  29. 29. SUPPLY CHAIN MANAGEMENT OPERATIONSSTRATEGIES STRATEGY WHEN TO CHOOSE BENEFITS Make to Stock standardized products, Low manufacturing costs; relatively predictable meet customer demands demand quickly Make to Order customized products, Customization; reduced many variations inventory; improved service levels Configure to Order many variations on Low inventory levels; wide finished product; range of product offerings; infrequent demand simplified planning Engineer to Order complex products, Enables response to specific unique customer customer requirements specifications 29
  30. 30. SUPPLY CHAIN IMPERATIVES FOR SUCCESS  View the supply chain as a strategic asset  Dell’s innovative direct-to-consumer sales and build-to-order manufacturing  Create unique supply chain configurations that align with your company’s strategic objectives  Operations strategy  Outsourcing strategy  Channel strategy Supply chain configuration components  Customer service strategy  Asset network  Reduce uncertainty  Forecasting  Collaboration  Integration 30
  31. 31. SUPPLY CHAIN COLLABORATION  Many different definitions depending on perspective  The means by which companies within the supply chain work together towards mutual goals by sharing  Ideas  Information  Processes  Knowledge  Information  Risks  Rewards  Why collaborate?  Accelerate entry into new markets  Changes the relationship between cost/value/profit equation 31
  32. 32. SUPPLY CHAIN COLLABORATION  The only method that has the potential to eliminate or minimize the Bullwhip effect Retailers Suppliers Synchronized Manufacturer Production Scheduling Collaborative Distributors/ Demand Collaborative Wholesalers Planning Product Development Collaborative Logistics Planning •Transportation services •Distribution center services Logistics Providers 32
