Importance of Purchasing
• Major cost center
– More wise to reduce cost than increase sales to increase
overall profits
• Affects quality of final product
• Aids strategy of low cost, response, and
differentiation
Objectives of the Purchasing
Function
• Helps identify the products and services
that can be best obtained externally –
Make / Buy decisions – outsourcing?
• Develops, evaluates, and determines the
best supplier, price, and delivery for those
products and services
Supply-Chain Strategies
• Must be in sync with OM strategy which in turn
should support overall company strategy
• Affects long-term competitive position
• Strategic options
– Many suppliers
– Few suppliers
– Vertical backward integration
Many Suppliers Strategy
• Many sources per item
• Lowest bidder wins order – focus on low cost
• Infrequent, large lots
• Long-term relations is not a goal
• Negotiated, sporadic
• Suppliers held responsible for reqd technology,
expertise, cost, quality and delivery competencies
Few Suppliers Strategy
• 1 or few sources per item
• Partnership (JIT); long-term, stable relations
• Allows suppliers to have economies of scale and a
learning curve, thus cutting down on prodn costs
• Reliability and quality given primary importance
• Frequent, small lots
• Delivery to point of use
• Drawback – both buyer and supplier run risk of
becoming captives to one another
Vertical Integration Strategy
• Ability to produce goods previously purchased
– Setup operations
– Buy supplier
• Results in cost reduction, quality adherence, timely delivery
• Issues
– Major financial commitment
– Hard to do all things well
– Dangerous for firms in industries undergoing technological change if
management not knowledgeable enough about the next wave of change
