The Supply Chain: Introduction
Value Chain versus Supply Chain
Value chain
–
–
every step from raw materials to the eventual end user
ultimate goal is delivery of maximum value to the end user
Supply chain
–
–
activities that get raw materials and subassemblies into manufacturing
operation
ultimate goal is same as that of value chain
Terms are used interchangeably
Value: creation of value for customer is important aspect of
supply chain management

Supply Chain Management (SCM)
Managing flow of information through supply chain in order to
attain the level of synchronization that will make it more
responsive to customer needs while lowering costs
Keys to effective SCM
– information
– communication
– cooperation
– trust

“Green” Supply Chains
• Sustainability
• Meeting present needs without compromising the ability of
future generations to meet their needs
• Sustaining human and social resources
• It can be cost effective and profitable
• Can provide impetus for product and process innovations
• Impulse comes from downstream in the supply chain and
moves upstream to suppliers

“Green” Supply Chains
Early success using Green SCM principles
Texas Instruments: Saves $8
million each year by reducing its
transit packaging budget for its
semiconductor business through
source reduction, recycling, and
use of reusable packaging
systems (20% annual savings).
Commonwealth Edison: Produced
$50 million in financial benefits
from managing materials and
equipment with a life-cycle
management approach.
Pepsi-Cola: Saved $44 million by
switching from corrugated to
reusable plastic shipping
containers for one liter and 20ounce bottles conserving 196
million pounds of corrugated
material.
Dow Corning: Saved $2.3 million
by using reconditioned steel
drums in 1995. Also conserved
7.8 million pounds of steel.

Study of “Successful practice”
Measuring the strategic value of sourcing:
• 44% of customers and 42% of service providers do not undertake formal
strategic reviews of the benefits to their business or sourcing contracts.
• 72% of the customers report that they do not have, or do not share with
their service providers, criteria for measuring the success or failure of
their sourcing arrangement.
