Chapter 11 Supply Chain Management
Section 1 The Supply Chain's Strategic Importance
1) Even though a firm may have a low cost strategy, supply-chain strategy can select suppliers primarily
on response or differentiation.

ensure speedy supply.
4) Savings in the supply chain exert more leverage as the firm's net profit margin decreases.
5) A firm that employs a response strategy should minimize inventory throughout the supply chain.
6) Supply chain decisions are not generally strategic in nature, because purchasing is not a large expense
for most firms.
7) Because service firms do not acquire goods and services externally, their supply chain management
issues are insignificant.

15) ________ describes the coordination of all supply chain activities, starting with raw materials and
ending with a satisfied customer.
16) As the corporate and operations management strategies vary from low cost to response to
differentiation, how does this impact the criteria used for selecting suppliers?
17) How does the pursuit of a response strategy impact the supply chain decisions of: (1) primary
supplier selection criteria, (2) supply chain inventory, (3) distribution network, and (4) product design
characteristics?
18) A grocery chain is interested in exploring the impact effective supply chain management would have.
Suppose that for every $1 of sales, 4% is profit, 50% is spent in the supply chain, and the remaining 46% is
evenly divided between fixed and production costs. If the chain can save $1 in the supply chain it would
take how many dollars of increased sales to have the same increase in profit? Assume that fixed costs are
fixed so that the portion of increased sales allocated to fixed costs is instead profit (27% profit margin
combined now).
19) A company is deciding where to assign its summer intern. The manager estimates that the intern can
