What can Supply Chain Management do?
Estimated that the grocery industry could save $30 billion (10% of operating
cost) by using effective logistics and supply chain strategies
– A typical box of cereal spends 104 days from factory to sale
– A typical car spends 15 days from factory to dealership
– Faster turnaround of the goods is better?
Laura Ashley (retailer of women and children clothes) turns its inventory 10
times a year five times faster than 3 years ago
– inventory is emptied 10 times a year, or an item spends about 12/10 months in the
inventory.
– To be responsive, it relocated its main warehouse next to FedEx hub in Memphis, TE.
National Semiconductor used air transportation and closed 6 warehouses, 34%
increase in sales and 47% decrease in delivery lead time.

the flows of material, information, and finances in supply chains.

 The task of SCM is to design, plan, and execute the activities at the different stages
so as to provide the desired levels of service to supply chain customers profitably

Importance of Supply Chain Management
 In 2000, the US companies spent $1 trillion (10% of GNP) on supply-related
activities (movement, storage, and control of products across supply chains).

Push vs Pull System
What instigates the movement of the work in the system?
In Push systems, work release is based on downstream demand
forecasts
– Keeps inventory to meet actual demand
– Acts proactively
» e.g. Making generic job application resumes today (e.g.: exempli gratia)
In Pull systems, work release is based on actual demand or the
actual status of the downstream customers
– May cause long delivery lead times
– Acts reactively
» e.g. Making a specific resume for a company after talking to the recruiter

Strategies
Marketing and sales strategy relates to positioning, pricing and
promotion of products/services
– e.g. Never offer more than 40% discount
– e.g. EDLP = every day low price
» At Wal-Mart
– e.g. Demand smoothing via coupons
» BestBuy
Supply chain management strategy relates to procurement,
transportation, storage and delivery
– e.g. Never use more than 1 supplier for every input
– e.g. Never expedite orders just because they are late
– e.g. Always use domestic suppliers within the sales season not in advance.

Loosing the strategic fit: Webvan
Webvan started a merger with HomeGrocer in Sept 2000 and
completed in May 2001.
Declared bankruptcy in July 2001. Why?
– “Webvan was so behemoth that could deliver anything to anyone anywhere
that it lost sight of a more mundane task: pleasing grocery customers day
after day”.
– Short to midterm cash mismanagement. Venture capital of $1.2 B run out.
– Merger costs: duplicated work force, integration of technology, realignment
of facilities.
Peapod has the same business model but more focused in terms of
service and locations. It actually survives with its parent company
Royal Ahold’s (Dutch Retailer) cash.
– Delivers now at a fee of $6.95 within a day.

Editor's Notes

  • #3 Notes:
  • #4 Notes: Traditionally logistics and supply chain management have been measured in terms of transportation and inventory costs and the administration required to manage both. Traditionally firms would have an inventory manager and a transportation manager. This view is very narrow and causes significant problems in the proper functioning of the supply chain.
  • #5 Notes: Key message here is that logistics costs are a significant fraction of the total value of a product. The problem here is that this a purely cost based view of the supply chain and drives a firm to simply reducing logistics costs. This is an incomplete picture.
  • #8 Notes: Supply chain involves everybody, from the customer all the way to the last supplier. Key flows in the supply chain are - information, product, and cash. It is through these flows that a supply chain fills a customer order. The management of these flows is key to the success or failure of a firm. Give Dell &amp; Compaq example, Amazon &amp; Borders example to bring out the fact that all supply chain interaction is through these flows.
  • #12 A customer is a supplier for some other company. A supplier is a customer for some other company. Not all pieces of a supply chain belongs to the same company.
  • #13 The supply chain is a concatenation of cycles with each cycle at the interface of two successive stages in the supply chain. Each cycle involves the customer stage placing an order and receiving it after it has been supplied by the supplier stage. One difference is in size of order. Second difference is in predictability of orders - orders in the procurement cycle are predictable once manufacturing planning has been done. This is the predominant view for ERP systems. It is a transaction level view and clearly defines each process and its owner.
  • #15 In this view processes are divided based on their timing relative to the timing of a customer order. Define push and pull processes. They key difference is the uncertainty during the two phases. Give examples at Amazon and Borders to illustrate the two views
  • #20 Competitive strategy: a set of customer needs that a company emphasizes and concentrates on while producing / servicing. Compare Wal-Mart, 7 eleven, Sam’s club.
