What should we do differently? Review of Module
The Supply Chain • Most companies create value by processing inputs to produce outputs • Fairly obvious in case of manufacturing • Also applies to trade; even to pure services • Inputs arrive via an upstream supply chain • We manage this via “Inbound logistics” • Outputs leave through a downstream supply chain • Which we manage with “Outbound logistics” • Logistics companies are intermediaries who support outsourcing of some of the logistics activity
Elements of Supply Chain Simplified View Chaffey (2007) Fig 6.1
Material and Information Flows • Every time you arrange the flow of goods and services along the supply chain, Data must flow too • For example: • Our warehouse stock falls below order threshold • We send order to supplier • Supplier sends goods • Supplier invoices us • We send payment transfer request to BACS • This data-intensive nature of supply chain makes it amenable to e-Business enhancement

Push or Pull? • “You can have it any color, so long as it’s black”(reputed to have been said of Model T Ford, by Ford) • Push involves • Innovation by manufacturer (e.g. new product development) • Identifying a target market • Recruiting channels to push product into that market • Pull is an approach that’s growing fast • Find out what the market wants • Respond with rapid, targeted development • Supply at rate determined by market (e.g. Print on Demand)
Push to customer Supplier Manufacturer Distributor Retailer Customer Push Approach to SCM • Typical Aim: Optimize production for cost & efficiency • Characteristics: Manufacturer-led product development Poor data integration Long cycle and response times, Large inventories needed • Use of IS: Independent data mgt by chain members Limited use of EDI Based on Chaffey (2007) Fig 6.3
Pull from customer Supplier Manufacturer Distributor Retailer Customer Pull approach to SCM • Typical Aim: Enhance product/service quality • Characteristics: Driven by Market Research; Technology used for research and data integration; Short cycle & response times; Low inventory levels through JIT • Use of IS: Integrated internal systems Information sharing across supply-chain Extensive use of B2B technologies Based on Chaffey (2007) Fig 6.3
The Value Chain • Analysis used to focus on “Direct” and “Indirect” • Primary activities that get goods/services to the consumer, versus • Support activities that provide infrastructure • Companies could sink into chaos by reducing investment in internal support (or become fat investing too much) • Chaffey (p.277*) offers a different model, where both elements add value over a wide range of activities • Recognizes value of each activity within a purpose • This analysis opens up opportunities to specialize • Or for integration along the supply chain * p.223 in 2nd edn
Traditional and Revised Models Not so much a revision as a different view of the way activities are integrated Chaffey (2007) Fig 6.4
Value Network • Term recognizes that value isn’t added by a constant chain, but varies between products, and with time • We should always consider a variety of suppliers • Potentially with variants of inbound logistics • Chaffey’s Fig 6.5 shows how this can support outsourcing • Driven by strategy (e.g. “core business,” “core capabilities”) • May want to use partners to integrate activities,not only as suppliers or distributors • Clearly, stock-holding does not contribute much value, as we only need what’s required immediately
Value Network of an Organization • Give examples of • Internet Service Provider • Wide Area Network • Application Service Provider Chaffey (2007) Fig 6.5
Restructuring the Supply Chain • Trend in mid-C20 was towards Vertical Integration • BMC bought Pressed Steel and other component suppliers • General Motors bought AC-Delco • Most oil companies remain vertically-integrated • Outsourcing boom of late C20 disaggregated companies • Motor manufacturers now mainly assembly plants • Most computers are built from bought-in components • Focus is on hanging on to unique technologies • Alternative approach is “Virtual Integration” • Rely totally on third-party suppliers, but • Integrate them into your SCM
Integration and Disintegration Chaffey (2007) Fig 6.7
What is “ordering online”? • If you already have a supplier/purchaser relationship • Orders can be pretty informal (e.g. e-mail), or • Use web-based form-filling, still by humans • Invoices can follow by conventional routes • Relationship can be automated • Purchaser’s system orders from suppliers’ systems • Requires secure systems to ensure transactions cannot be repudiated and that supplier will be paid • Or we can build relationships on the fly • Using B2B exchanges • Or, given standards, we can shop around directly

Information Systems for SCM • JIT won’t work unless you have shared planning • Example: if Tesco does a BOGOF on Baxter’s soup,can Baxter’s crank up production fast enough? • Supply planning needs to consider aspects of demand planning • ERP (Enterprise Resource Planning) systems like SAP handle all operational activities • Supported by operational database and • Data warehouse (tactical support for the planning process)
Typical IS Infrastructure for SCM Chaffey (2007) Fig 6.11
Tesco Case Study (Chaffey p.292) Based on Nairn’s Financial Times article 3 May 2000 • Goal was to enhance collaboration across supply chain • Network linked 1300 of 2000 suppliers (96% by volume) • 350 receive EDI messages: demand, stock, forecasts • Goal is to shift product mgt responsibility to supplier • Funding from suppliers (£100 to £100K, depending on size) • Suppliers now often see problems before Tesco • Promotions management added in 1999 • St Ivel saved 30% on annual promotion costs • “Seamless planning” with input shared between Tesco and the supplier

Summary • SCM Coordinates all supply activities of a company • Upstream/Inbound – getting the inputs needed to create added value • Downstream/Outbound – routing the outputs to customers, directly or indirectly • “Chain” is usually a network • Inputs include: • Items incorporated in our products (steel, screws, circuits) • Things we need to run our business (paper, toner, desks) • Ideally, we optimize every element of the supply network
