  • Is this the future? Is our increased application of technology forcing both individuals and organizations to become specialists in relatively narrow areas? What problems is this likely to cause? This is probably a good example to discuss in detail. Points which might be raised include: - What differences might one expect between Volkswagen’s employment of 800 of its own workers versus 800 workers from a variety of companies? - What risks does this practice raise for VW? - What changes must VW make to integrate the workers from the other companies into the VW organization? - While this might work in Brazil, would it work equally well in the U.S.?
  • Probably the most important point to be made here is the encompassing nature of supply-chain management - from suppliers’ suppliers through internal production through distribution to the customer.
  • This slide might be used to make the point about the various “flows” - material, information, money.
  • Students should be asked to explain the differences illustrated by these graphs.
  • This and the following two slides look at how supply-chain strategy can support overall strategy.
  • Students might be asked how they believe the role of purchasing is changing given the increased use of information technology and strategies such as JIT.
  • This slide should further impress upon students the importance of the purchasing function.
  • This slide emphasizes the role of efficiency of purchasing.
  • While these are the main functions of purchasing, one would also expect the purchasing department to participate in make-buy decisions.
  • Students should be asked to consider how this traditional process might be changed through process reengineering and the effective application of information technology. (paperless purchasing?) How does the nature of this process change in a virtual company?
  • The strategic options listed are expanded upon in later slides.
  • Subsequent slides expand upon these strategies.
  • We read in the management literature more and more about “managing relationships.” If you use the “many supplier” strategy, how do you develop useful relationships?
  • The risk of having only a single supplier will probably be obvious to most students. What nature of relationship must you have with your supplier to reduce this risk?
  • Under what conditions is vertical integration an appropriate strategy? Would we choose it simply if the item production/purchase cost would be less?
  • Students should be asked to consider why, other than on a “cost” basis, a company might want to consider vertical integration.
  • Students might be asked to consider what it would take to implement such a system in the U.S.
  • Students should be asked to consider the problems in establishing a virtual company, such as: - how does one decide which companies to ask to join their alliance? - how is the decision to share revenues made? - how is performance evaluated? - etc.
  • Students should be asked to consider the problems which might be encountered at each step in this process.
  • Students might be asked to consider what additional information they might want before approving a vendor selection.
  • Students might be asked if they perceive one or another of these criteria to be especially important. Also, are there other criteria they would prefer to use or think should be added? (One such criteria might be the ability to communicate using EDT)
  • Ask students under what conditions each of these models might be appropriate.
  • Ask students to consider the conditions under which each of these options might be appropriate.
  • In addition to framing the materials management function, this slide raises the issue of “how does one begin assigning responsibilities for each of the facets of supply-chain management?”
  • Here you might simply discuss some of the options available under each of the categories listed.
  • This slide summarizes some of the benefits of effective supply-chain management.
