2. A G ENERAL F RAMEWORK Two distinct chains in organizations: The supply chain which focuses on the flow of physical products from suppliers through manufacturing and distribution all the way to retail outlets and customers, and The development chain which focuses on new product introduction and involves product architecture, make/buy decisions, earlier supplier involvement, strategic partnering, supplier footprint and supply contracts.

8. D ESIGN FOR L OGISTICS (DFL) Product and process design that help to control logistics costs and increase service levels Economic packaging and transportation Concurrent and parallel processing Standardization

9. E CONOMIC T RANSPORTATION AND S TORAGE Design products so that they can be efficiently packed and stored Design packaging so that products can be consolidated at cross docking points Design products to efficiently utilize retail space

10. E XAMPLES Ikea World’s largest furniture retailer 131 stores in 21 countries Large stores, centralized manufacturing, compactly and efficiently packed products Rubbermaid Clear Classic food containers - designed to fit 14x14” Wal- Mart shelves

11. F INAL P ACKAGING Delay until as late as possible Repackaging at the cross-docking point is common for many products

12. C ONCURRENT /P ARALLEL P ROCESSING Objective is to minimize lead times Achieved by redesigning products so that several manufacturing steps can take place in parallel Modularity/Decoupling is key to implementation Enables different inventory levels for different parts

13. T RADITIONAL M ANUFACTURING Set schedules as early as possible Use large lot sizes to make efficient use of equipment and minimize costs Large centralized facilities take advantage of economies of scale

14. Recall: aggregate demand information is more reliable We can have better forecasts for a product family (rather than a specific product or style) How to make use of aggregate data ? Designing the product and manufacturing processes so that decisions about which specific product is being manufactured (differentiation) can be delayed until after manufacturing is under way S TANDARDIZATION

15. M ODULARITY IN P RODUCT AND P ROCESS Modular Product: Can be made by appropriately combining the different modules It entails providing customers a number of options for each module Modular Process: Each product undergo a discrete set of operations making it possible to store inventory in semi- finished form Products differ from each other in terms of the subset of operations that are performed on them

16. M ODULARITY IN P RODUCT AND P ROCESS Semiconductor wafer fabrication is modular since the type of chip produced depends on the unique set of operations performed Oil refining is not modular since it is continuous and inventory storage of semi-finished product is difficult

17. M ODULARITY IN P RODUCT AND P ROCESS Modular products are not always made from modular processes Bio-tech and pharmaceutical industries make modular products but use non-modular processes; many products are made by varying the mix of a small number of ingredients

18. S WAMINATHAN ’ S F OUR A PPROACHES TO S TANDARDIZATION Part standardization Process standardization Product standardization Procurement standardization

19. P ART S TANDARDIZATION Common parts used across many products. Common parts reduce: inventories due to risk pooling costs due to economies of scale Excessive part commonality can reduce product differentiation May be necessary to redesign product lines or families to achieve commonality

20. P ROCESS S TANDARDIZATION Standardize as much of the process as possible for different products Customizing the products as late as possible Decisions about specific product to be manufactured is delayed until after manufacturing is under way Starts by making a generic or family product Differentiate later into a specific end-product Postponement or delayed product differentiation

21. D ELAYED D IFFERENTIATION May be necessary to redesign products specifically for delayed differentiation May be necessary to resequence the manufacturing process to take advantage of process standardization Resequencing modify the order of product manufacturing steps resequenced operations result in the differentiation of specific items or products are postponed as much as possible

23. B ENETTON B ACKGROUND A world leader in knitwear Massive volume, many stores Logistics Large, flexible production network Many independent subcontractors Subcontractors responsible for product movement Retailers Many, small stores with limited storage

24. B ENETTON S UPPLY C YCLE Primary collection in stores in January Final designs in March of previous year Store owners place firm orders through July Production starts in July based on first 10% of orders August - December stores adjust orders (colors) 80%-90% of items in store for January sales Mini collection based on customer requests designed in January for Spring sales To refill hot selling items Late orders as items sell out Delivery promised in less than five weeks

25. B ENETTON F LEXIBILITY Business goals Increase sales of fashion items Continue to expand sales network Minimize costs Flexibility important in achieving these goals Hard to predict what items, colors, etc. will sell Customers make requests once items are in stores Small stores may need frequent replenishments

26. I T I S H ARD TO B E F LEXIBLE W HEN... Lead times are long Retailers are committed to purchasing early orders Purchasing plans for raw materials are based upon extrapolating from 10% of the orders

29. B ENETTON P OSTPONEMENT Why the change? The change enables Benetton to start manufacturing before color choices are made What does the change result in? Delayed forecasts of specific colors Still use aggregate forecasts to start manufacturing early React to customer demand and suggestions Issues with postponement Costs are 10% higher for manufacturing New processes had to be developed New equipment had to be purchased

30. P RODUCT S TANDARDIZATION Downward Substitution Produce only a subset of products (because producing each one incurs high setup cost) Guide customers to existing products Substitute products with higher feature set for those with lower feature set Which products to offer, how much to keep, how to optimally substitute ?

31. P ROCUREMENT S TANDARDIZATION Consider a large semiconductor manufacturer The wafer fabrication facility produces highly customized integrated circuits Processing equipment that manufactures these wafers are very expensive with long lead time and are made to order Although there is a degree of variety at the final product level, each wafer has to undergo a common set of operations The firm reduces risk of investing in the wrong equipment by pooling demand across a variety of products

32. O PERATIONAL S TRATEGIES FOR S TANDARDIZATION Process NonmodularModular Product ModularParts standardizationProcess standardization NonmodularProduct standardizationProcurement standardization

33. S ELECTING THE S TANDARDIZATION S TRATEGY If process and product are modular, process standardization will help to maximize effective forecast accuracy and minimize inventory costs. If the product is modular, but the process is not, it is not possible to delay differentiation. However, part standardization is likely to be effective. If the process is modular but the product is not, procurement standardization may decrease equipment expenses. If neither the process nor the product is modular, some benefits may still result from focusing on product standardization.

34. P USH -P ULL B OUNDARY Pull-based systems typically lead to: reduction in supply chain lead times, inventory levels, and system costs making it easier to manage system resources Not always practical to implement a pull- based system throughout the entire supply chain Lead times may be too long May be necessary to have economies of scale in production or transportation. Standardization strategies can combine push and pull systems Portion of the supply chain prior to product differentiation is typically a push-based supply chain Portion of the supply chain starting from the time of differentiation is a pull-based supply chain.

35. S UPPLIER I NTEGRATION INTO N EW P RODUCT D EVELOPMENT Traditionally suppliers have been selected after design of product or components However, firms often realize tremendous benefits from involving suppliers in the design process. Benefits include: a decline in purchased material costs an increase in purchased material quality a decline in development time and cost an increase in final product technology levels.

36. T HE S PECTRUM OF S UPPLIER I NTEGRATION No single “appropriate level” of supplier integration None Supplier is not involved in design. Materials/subassemblies supplied as per customer specifications/design White box Informal level of integration Buyer “consults” with the supplier informally when designing products and specifications No formal collaboration Grey box Formal supplier integration Collaborative teams between buyer’s and supplier’s engineers Joint development Black box Buyer gives the supplier a set of interface requirements Supplier independently designs and develops the required component

37. A PPROPRIATE L EVEL D EPENDS ON THE S ITUATION Process Steps to follow: Determine internal core competencies. Determine current and future new product developments. Identify external development and manufacturing needs.

38.

39. K EYS TO S UPPLIER I NTEGRATION Making the relationship a success: Select suppliers and build relationships with them Align objectives with selected suppliers Which suppliers can be integrated? Capability to participate in the design process Willingness to participate in the design process Ability to reach agreements on intellectual property and confidentiality issues. Ability to commit sufficient personnel and time to the process. Co-locating personnel if appropriate Sufficient resources to commit to the supplier integration process.

40. M ASS C USTOMIZATION Evolved from the two prevailing manufacturing paradigms of the 20th century Craft production and mass production. Mass production efficient production of a large quantity of a small variety of goods High priority on automating and measuring tasks Mechanistic organizations with rigid controls Craft production involves highly skilled and flexible workers Often craftsmen Organic organizations which are flexible and changing

41. A BSENCE OF T RADE -O FFS Two types meant inherent trade-offs Low-cost, low-variety strategy may be appropriate for some products For others, a higher-cost, higher-variety, more adaptable strategy was more effective Development of mass customization implies it is not always necessary to make this trade-off Mass customization delivery of a wide variety of customized goods or services quickly and efficiently at low cost captures many of the advantages of both the mass production and craft production systems not appropriate for all products gives firms important competitive advantages helps to drive new business models

42. M AKING M ASS C USTOMIZATION W ORK Highly skilled and autonomous workers, processes, and modular units Managers can coordinate and reconfigure these modules to meet specific customer requests and demands

43. K EY A TTRIBUTES Instantaneous Modules and processes must be linked together very quickly Allows rapid response to various customer demands. Costless Linkages must add little if any cost to the processes Allows mass customization to be a low-cost alternative. Seamless Linkages and individual modules should be invisible to the customer Frictionless Networks or collections of modules must be formed with little overhead. Communication must work instantly

44. M ASS C USTOMIZATION AND SCM Many of the advanced SCM approaches and techniques essential if mass customization is to be successfully implemented IT critical for effective SCM is also critical for coordinating different modules Concepts like strategic partnerships and supplier integration essential for the success of mass customization. Postponement can play a key role in implementing mass customization
