- 1. Chapter 3 Supply Chain Drivers and Metrics 1 Dr S K Sharma, BITS Pilani
- 2. Financial Measures Of Performance • Measuring the link between SC performance and business performance is critical for two important stakeholders viz customer and shareholders • From a shareholder perspective, return on equity (ROE) is the main summary measure of a firm’s performance 2 Dr S K Sharma, BITS Pilani
- 3. Financial Measures of Performance • Return on assets (ROA) measures the return earned on each dollar invested by the firm in assets assets total Average interest before Earnings ROA assets total Average ) rate Tax – 1 ( expense Interest income Net 3 Dr S K Sharma, BITS Pilani
- 4. Financial Data for Amazon Table 3-1 4 Dr S K Sharma, BITS Pilani
- 5. Financial Measures Of Performance • An important ratio that defines financial leverage is accounts payable turnover (APT) payable Accounts sold goods of Cost APT 5 Dr S K Sharma, BITS Pilani
- 6. Financial Measures Of Performance • ROA can be written as the product of two ratios—profit margin and asset turnover margin) Profit ( revenue Sales interest before Earnings ROA over) Asset turn ( assets Total revenue Sales 6 Dr S K Sharma, BITS Pilani
- 7. Financial Measures of Performance • Cash-to-cash (C2C) cycle roughly measures the average amount time from when cash enters the process as cost to when it returns as collected revenue C2C = – days payable (1/APT) + days in inventory (1/INVT) + days receivable (1/ART) 7 Dr S K Sharma, BITS Pilani
- 8. Drivers of Supply Chain Performance • Facilities The physical locations in the supply chain network where product is stored, assembled, or fabricated • Inventory All raw materials, work in process, and finished goods within a supply chain • Transportation Moving inventory from point to point in the supply chain 8 Dr S K Sharma, BITS Pilani
- 9. Drivers of Supply Chain Performance • Information Data and analysis concerning facilities, inventory, transportation, costs, prices, and customers throughout the supply chain • Sourcing Who will perform a particular supply chain activity • Pricing How much a firm will charge for the goods and services that it makes available in the supply chain 9 Dr S K Sharma, BITS Pilani
- 10. Supply chain- Finance linkage Dr S K Sharma, BITS Pilani 10
- 11. A Framework for Structuring Drivers Figure 3-1 11 Dr S K Sharma, BITS Pilani
- 12. Facilities • Role in the supply chain The “where” of the supply chain Manufacturing or storage (warehouses) • Role in the competitive strategy Economies of scale (efficiency priority) Larger number of smaller facilities (responsiveness priority) Toyata and Honda reaped the benefits of opening local facilities 12 Dr S K Sharma, BITS Pilani
- 13. Facilities • Components of facilities decisions Role Flexible, dedicated, or a combination of the two Product focus or a functional focus Warehouses or DC’s cross docking or storage Location Where a company will locate its facilities Centralize/decentralize, macroeconomic factors, quality of workers, cost of workers and facility, availability of infrastructure, proximity to customers, location of other facilities, tax effects Contd… 13 Dr S K Sharma, BITS Pilani
- 14. Facilities • Components of facilities decisions Capacity A facility’s capacity to perform its intended function or functions Excess capacity – responsive, costly Little excess capacity – more efficient, less responsive 14 Dr S K Sharma, BITS Pilani
- 15. Facilities • Components of facilities decisions Facility-related metrics Capacity Utilization Processing/setup/down/idle time Production cost per unit Quality losses Theoretical flow/cycle time of production Actual average flow/cycle time Product variety Avg production batch size 15 Dr S K Sharma, BITS Pilani
- 16. Facilities • Overall trade-off: Responsiveness versus efficiency Cost of the number, location, capacity, and type of facilities (efficiency) and the level of responsiveness Increasing the number of facilities increases facility and inventory costs but decreases transportation costs and reduces response time Increasing the flexibility or capacity of a facility increases facility costs but decreases inventory costs and response time 16 Dr S K Sharma, BITS Pilani
- 17. Inventory • Role in the supply chain Mismatch between supply and demand Satisfy demand Exploit economies of scale Impacts assets, costs, responsiveness, material flow time Material flow time: The time that elapses between the point at which material enters the supply chain to the point at which it exits Throughput, the rate at which sales occur Little’s law I = DT where, I = flow time, T = throughput, D = demand 17 Dr S K Sharma, BITS Pilani
- 18. Inventory • Role in competitive strategy Form, location, and quantity of inventory allow a supply chain to range from being very low cost to very responsive Objective is to have right form, location, and quantity of inventory that provides the right level of responsiveness at the lowest possible cost Amazon keeps best selling items in many regional warehouses near to customers and keeps slower moving books at fewer warehouses to lower the cost of inventory 18 Dr S K Sharma, BITS Pilani
- 19. Components of Inventory Decisions • Cycle inventory Average amount of inventory used to satisfy demand between shipments Function of lot size decisions • Safety inventory Costs of carrying too much inventory versus cost of losing sales Inventory held in case demand exceeds expectations 19 Dr S K Sharma, BITS Pilani
- 20. Components of Inventory Decisions • Seasonal inventory Inventory built up to counter predictable variability in demand Cost of carrying additional inventory versus cost of flexible production • Level of product availability The fraction of demand that is served on time from product held in inventory Trade off between customer service and cost 20 Dr S K Sharma, BITS Pilani
- 21. Components of Inventory Decisions • Inventory-related metrics Cash-to-cash cycle time Average inventory Inventory turns Products with more than a specified number of days of inventory Average replenishment batch size Average safety inventory Seasonal inventory Fill rate Fraction of time out of stock Obsolete inventory 21 Dr S K Sharma, BITS Pilani
- 22. Inventory • Overall trade-off: Responsiveness versus efficiency Increasing inventory generally makes the supply chain more responsive A higher level of inventory facilitates a reduction in production and transportation costs because of improved economies of scale Inventory holding costs increase 22 Dr S K Sharma, BITS Pilani
- 23. Transportation • Role in the supply chain Moves the product between stages in the supply chain Impact on responsiveness and efficiency Faster transportation allows greater responsiveness but lower efficiency Also affects inventory and facilities 23 Dr S K Sharma, BITS Pilani
- 24. Transportation • Role in the competitive strategy Allows a firm to adjust the location of its facilities and inventory to find the right balance between responsiveness and efficiency • Components of transportation decisions Design of transportation network Modes, locations, and routes Direct or with intermediate consolidation points One or multiple supply or demand points in a single run 24 Dr S K Sharma, BITS Pilani
- 25. Transportation • Choice of transportation mode Air, truck, rail, sea, and pipeline Information goods via the Internet Different speed, size of shipments, cost of shipping, and flexibility 25 Dr S K Sharma, BITS Pilani
- 26. Transportation • Transportation-related metrics Average inbound transportation cost Average income shipment size Average inbound transportation cost per shipment Average outbound transportation cost Average outbound shipment size Average outbound transportation cost per shipment Fraction transported by mode 26 Dr S K Sharma, BITS Pilani
- 27. Transportation • Overall trade-off: Responsiveness versus efficiency The cost of transporting a given product (efficiency) and the speed with which that product is transported (responsiveness) Using fast modes of transport raises responsiveness and transportation cost but lowers the inventory holding cost 27 Dr S K Sharma, BITS Pilani
- 28. Information • Role in the supply chain Improve the utilization of supply chain assets and the coordination of supply chain flows to increase responsiveness and reduce cost Information is a key driver that can be used to provide higher responsiveness while simultaneously improving efficiency 28 Dr S K Sharma, BITS Pilani
- 29. Information • Role in the competitive strategy Right information can help a supply chain better meet customer needs at lower cost Improves visibility of transactions and coordination of decisions across the supply chain Share the minimum amount of information required to achieve coordination 29 Dr S K Sharma, BITS Pilani
- 30. Components of Information Decisions • Push versus pull Different information requirements and uses • Coordination and information sharing Supply chain coordination, all stages of a supply chain work toward the objective of maximizing total supply chain profitability based on shared information • Sales and operations planning (S&OP) The process of creating an overall supply plan (production and inventories) to meet the anticipated level of demand (sales) 30 Dr S K Sharma, BITS Pilani
- 31. Components of Information Decisions • Enabling technologies Electronic data interchange (EDI) The Internet Enterprise resource planning (ERP) systems Supply chain management (SCM) software Radio frequency identification (RFID) 31 Dr S K Sharma, BITS Pilani
- 32. Components of Information Decisions • Information-related metrics Forecast horizon Frequency update Forecast error Seasonal factors Variance from plan Ratio of demand variability to order variability 32 Dr S K Sharma, BITS Pilani
- 33. Information • Overall trade-off: Complexity versus value Good information helps a firm improve both efficiency and responsiveness More information is not always better More information increases complexity and cost of both infrastructure and analysis exponentially while marginal value diminishes Evaluate the minimum information required to accomplish the desired objectives 33 Dr S K Sharma, BITS Pilani
- 34. Sourcing • Role in the supply Chain Set of business processes required to purchase goods and services Will tasks be performed by a source internal to the company, or a third party Globalization creates many more sourcing options with both considerable opportunity and potential risk 34 Dr S K Sharma, BITS Pilani
- 35. Sourcing • Role in the competitive strategy Sourcing decisions are crucial because they affect the level of efficiency and responsiveness in a supply chain Outsource to responsive third parties if it is too expensive to develop their own Keep responsive process in-house to maintain control 35 Dr S K Sharma, BITS Pilani
- 36. Components of Sourcing Decisions • In-house or outsource Perform a task in-house or outsource it to a third party • Supplier selection Number of suppliers, evaluation and selection criteria, direct negotiations or auction • Procurement The supplier sends product in response to customer orders 36 Dr S K Sharma, BITS Pilani
- 37. Components of Sourcing Decisions • Sourcing-related metrics Days payable outstanding Average purchase price Range of purchase price Average purchase quantity Supply quality Supply lead time Fraction of on-time deliveries Supplier reliability 37 Dr S K Sharma, BITS Pilani
- 38. Sourcing • Overall trade-off: Increase the supply chain surplus Increase the size of the total surplus to be shared across the supply chain Impact of sourcing on sales, service, production costs, inventory costs, transportation costs, and information cost Outsource if it raises the supply chain surplus more than the firm can on its own Keep function in-house if the third party cannot increase the supply chain surplus or if the outsourcing risk is significant 38 Dr S K Sharma, BITS Pilani
- 39. Pricing • Role in the supply chain Pricing determines the amount to charge customers for goods and services Affects the supply chain level of responsiveness required and the demand profile the supply chain attempts to serve Pricing strategies can be used to match demand and supply 39 Dr S K Sharma, BITS Pilani
- 40. Pricing • Role in the competitive strategy Firms can utilize optimal pricing strategies to improve efficiency and responsiveness Pricing strategies vary to meet different customer responsiveness requirements 40 Dr S K Sharma, BITS Pilani
- 41. Components of Pricing Decisions • Pricing and economies of scale The provider of the activity must decide how to price it appropriately to reflect these economies of scale • Everyday low pricing versus high-low pricing Different pricing strategies lead to different demand profiles that the supply chain must serve 41 Dr S K Sharma, BITS Pilani
- 42. Components of Pricing Decisions • Fixed price versus menu pricing If marginal supply chain costs or the value to the customer vary significantly along some attribute, it is often effective to have a pricing menu Can lead to customer behavior that has a negative impact on profits 42 Dr S K Sharma, BITS Pilani
- 43. Components of Pricing Decisions • Pricing-related metrics Profit margin Days sales outstanding Incremental fixed cost per order Incremental variable cost per unit Average sale price Average order size Range of sale price Range of periodic sales 43 Dr S K Sharma, BITS Pilani
- 44. Pricing • Overall trade-off: Increase firm profits Understand of the cost structure of performing a supply chain activity and the value this activity brings to the supply chain Strategy may support efficiency in the supply chain, lower supply chain costs, defend market share, or steal market share Differential pricing may be used to attract customers with varying needs Strategy should help either increase revenues or shrink costs or preferably both 44 Dr S K Sharma, BITS Pilani
- 45. Summary of Learning Objectives • Describe key financial measures of firm performance • Identify the major drivers of supply chain performance • Discuss the role of each driver in creating strategic fit between the supply chain strategy and the competitive strategy • Define the key metrics that track the performance of the supply chain in terms of each driver 45 Dr S K Sharma, BITS Pilani
