Supply Chain
“The global network used to deliver products
and services from raw materials to end
customers through an engineered flow of
information, physical distribution, and cash.”
APICS Dictionary, 13th Edition
Supply Chain Uncertainty
Forecasting, lead times, batch
ordering, price fluctuations, and
inflated orders contribute to
variability
Inventory is a form of insurance
Distorted information is one of the
main causes of uncertainty Bullwhip
effect
Information in the
Supply Chain
Centralized coordination of
information flows
Integration of transportation,
distribution, ordering, and production
Direct access to domestic and global
transportation and distribution
channels
Locating and tracking the movement of
every item in the supply chain - RFID
Bar Codes
Computer readable codes attached to
items flowing through the supply chain
Generates point-of-sale data which is
useful for determining sales trends,
ordering, production scheduling, and
deliver plans

IT Issues
Increased benefits and sophistication come
with increased costs
Efficient web sites do not necessarily mean
the rest of the supply chain will be as efficient
Security problems are very real – camera
phones, cell phones, thumb drives
Collaboration and trust are important
elements that may be new to business
relationships
Suppliers
Purchased materials account for about half
of manufacturing costs
Materials, parts, and service must be
delivered on time, of high quality, and low
cost
Suppliers should be integrated into their
customers’ supply chains
Partnerships should be established
On-demand delivery (JIT) is a frequent
requirement - what is JIT and does it work?
Sourcing
Relationship between customers and suppliers
focuses on collaboration and cooperation
Outsourcing has become a long-term strategic
decision
Organizations focus on core competencies
Single-sourcing is
increasingly a part
How does
of supplier relations
single source
Barriers
differ from sole
source?
Sourcing and Suppliers

Supplier Selection
Selection Evaluation
Supplier Certification
Sourcing and Ethics
Distribution
The actual movement of products and
materials between locations
Handling of materials and products at
receiving docks, storing products,
packaging, and shipping
Often called logistics
Driving force today
is speed
Distribution Centers
and Warehousing
DCs are some of the largest business
facilities in the United States
Trend is for more frequent orders in
smaller quantities
Flow-through facilities and automated
material handling
Final assembly and product
configuration (postponement) may be
done at the DC
Transportation
Railroads
95,000 - 150,000 miles in US
Low cost, high-volume
Improving flexibility
intermodal service
double stacking
Complaints: slow, inflexible, large loads
Advantages: large/bulky loads, intermodal
Trucking
Most used mode in US -75% of total
freight (volume not total weight)
Flexible, small loads
Consolidation,
Internet load match sites
Truck load (TL) vs. Less Than Truck Load
(LTL)
Air
Lightweight, small items
Quick, reliable, expensive (relatively
expensive depending on costs of not
getting item there)
Major airlines and US Postal Service,
UPS, FedEx
Package Carriers
UPS, US Postal Service, FedEx Ground
Significant growth driven by
e-businesses and the move to smaller
shipments and consumer desire to have it
NOW
Use several modes of transportation
Innovative use of technologies in some
cases
Online tracking – some better than others
Intermodal
Combination of several modes of
transportation
Most common are truck/rail/truck and
truck/water/rail/truck
Enabled by the use of containers – the
development of the 20 and 40 foot
containers significantly changed the face
of shipping
Switching Milk
Cans from a
Farmer’s Buggy
to a Truck on a
Rural Road in
North Carolina,
1929
Early form of intermodal transport and cross docking
Water
One of oldest means of transport
Low-cost, high-volume, slow (relative)
Security - sheer volume - millions of
containers annually
Bulky, heavy and/or large items
Standardized shipping containers improve
service
The most common form of international
shipping
Pipelines
Primarily for oil & refined oil products
Slurry lines carry coal or kaolin
High initial capital investment
Low operating costs
Can cross difficult terrain
Global Supply Chain
Free trade & global opportunities
Nations form trading groups
No tariffs or duties
Freely transport
goods across borders
Security!!
Quality
Management
Quality is a measure of goodness that is
inherent to a product or service.
Bottom line: perspective has to be from the
Customer – fitness for use
What Is Quality?
“The degree of excellence of a thing”
(Webster’s Dictionary)
“The totality of features and
characteristics that satisfy needs” (ASQ)
Fitness for use
Quality of design
Quality
• Quality Management – not owned by any
functional area – cross functional
• Measure of goodness that is inherent to a
product or service
FedEx and Quality
• Digitally Assisted Dispatch System – communicate
with 30K couriers
• 1-10-100 rule
1 – if caught and fixed as soon as it occurs, it
costs a certain amount of time and money to fix
10 – if caught later in different department or
location = as much as 10X cost
100 – if mistake is caught by the customer =
as much as 100X to fix
Product Quality Dimensions
• Product Based – found in the product
attributes
• User Based – if customer satisfied
• Manufacturing Based – conform to specs
• Value Based – perceived as providing good
value for the price
Dimensions of Quality (Garvin)

Product Development
Introduction
Product Development is a process which generates
concepts, designs, and plans to create services and
goods to meet customer needs.
1. Analyze market to assess need
2. Design product
3. Design process for making product
4. Develop plan to market product
5. Develop plan for full-scale production
6. Analyze financial feasibility
Increasing Importance of
Product Development
1. Customers demand greater product variety.
2. Customers are causing shorter product life cycles.
3. Improving technology is causing new products to
be introduced
4. The impact of increasing product variety and
shortening product life cycles is having a
multiplicative effect on the need for product
development.
5. Today, in order to be competitive, the firm may
have to produce many different products with a
life cycle of only five years or less. End of Life
