E-Supply Chains
Supply Chain Parts
Upstream supply chain
procurement
The process made up of a range of activities by
which an organization obtains or gains access to
the resources (materials, skills, capabilities,
facilities) they require to undertake their core
business activities
Internal supply chain
Downstream supply chain
7-6
E-Supply Chains
supply chain management (SCM)
A complex process that requires the
coordination of many activities so that the
shipment of goods and services from supplier
right through to customer is done efficiently
and effectively for all parties concerned. SCM
aims to minimize inventory levels, optimize
production and increase throughput, decrease
manufacturing time, optimize logistics and
distribution, streamline order fulfillment, and
overall reduce the costs associated with these
activities
7-7
E-Supply Chains
e-supply chain management (e-SCM)
The collaborative use of technology to improve
the operations of supply chain activities as well
as the management of supply chains
The success of an e-supply chain depends on:
The ability of all supply chain partners to view
partner collaboration as a strategic asset
A well-defined supply chain strategy
Information visibility along the entire supply chain
Speed, cost, quality, and customer service
Integrating the supply chain more tightly

indirect materials and employs several Web-based
functions such as online catalogs, contracts, purchase
orders, and shipping notices
collaborative planning
A business practice that combines the business
knowledge and forecasts of multiple players along a
supply chain to improve the planning and fulfillment of
customer demand

E-Supply Chains
Determining the Right Supply Chain
Strategy
Functional products are staple products that have
stable and predictable demand and call for a
simple, efficient, low-cost supply chain
Innovative products tend to have higher profit
margins, volatile demand, and short product life
cycles. These products require a supply chain that
emphasizes speed, responsiveness, and flexibility
rather than low costs
7-12
Supply Chain
Problems and Solutions
Typical Problems along the Supply Chain
With increasing globalization and offshoring, supply
chains can be very long and involve many internal
and external partners located in different places
A lack of logistics infrastructure might prevent the
right goods from reaching their destinations on time
Quality problems with materials and parts also can
contribute to deficiencies in the supply chain

Collaborative Commerce
Barriers to C-Commerce
Most organizations have achieved only
moderate levels of collaboration because of:
A lack of internal integration, standards, and
networks
Security and privacy concerns, and distrust over
who has access to and control of information
stored in a partner’s database
Internal resistance to information sharing and to
new approaches
A lack of internal skills to conduct c-commerce

Materials management
Distribution
Customer service
Sales forecasting
7-50
Impact of E-Commerce on Supply Chain Management
Electronic commerce and the Internet are fundamentally changing the nature of
supply chains, and redefining how consumers learn about, select, purchase, and
use products and services. The result has been the emergence of new businessto business supply chains that are consumer-focused rather than productfocused. They also provide customized products and services.
E-commerce impacts supply chain management in a variety of keyways. These
include:Cost efficiency: E-commerce allows transportation companies
of all sizes to exchange cargo documents electronically over the Internet.
E-commerce enables shippers, freight forwarders and trucking firms to
streamline document handling without the monetary and time investment
required by the traditional document delivery systems.
By using e-commerce, companies can reduce costs, improve data
accuracy, streamline business processes, accelerate business cycles,
and enhance customer service. Ocean carriers and their trading partners
can exchange bill of lading instructions, freight invoices, container status
messages, motor carrier shipment instructions, and other documents
with increased accuracy and efficiency by eliminating the need to re-key
or reformat documents. The only tools needed to take advantage of this
solution are a personal computer and an Internet browser.
7-51
Impact of E-Commerce on Supply Chain Management
Changes in the distribution system: E-commerce will give businesses more flexibility in
managing the increasingly complex movement of products and information between
businesses, their suppliers and customers. E-commerce will close the link between customers
and distribution centers. Customers can manage the increasingly complex movement of
products and information through the supply chain.
Ø
Customer orientation: E-commerce is a vital link in the support of logistics and
transportation services for both internal and external customers. E-commerce will help
companies deliver better services to their customers, accelerate the growth of the ecommerce initiatives that are critical to their business, and lower their operating costs. Using
the Internet for e-commerce will allow customers to access rate information, place delivery
orders, track shipments and pay freight bills.
E-commerce makes it easier for customers to do business with companies: Anything that
simplifies the process of arranging transportation services will help build companies' business
and enhance shareholder value. By making more information available about the commercial
side of companies, businesses will make their web site a place where customers will not only
get detailed information about the services the company offers, but also where they can
actually conduct business with the company.
Ultimately, web sites can provide a universal, self-service system for customers. Shippers can
order any service and access the information they need to conduct business with
transportation companies exclusively online. E-commerce functions are taking companies a
substantial step forward by providing customers with a faster and easier way to do business
with them.
7-52
Impact of E-Commerce on Supply Chain Management
Shipment tracking: E-commerce will allow users to establish an account and obtain real-time
information about cargo shipments. They may also create and submit bills of lading, place a cargo order,
analyze charges, submit a freight claim, and carry out many other functions. In addition, e-commerce allows
customers to track shipments down to the individual product and perform other supply chain management and
decision support functions. The application uses encryption technology to secure business transactions.
Ø
Ø
Shipping notice: E-commerce can help automate the receiving process by electronically transmitting a
packing list ahead of the shipment. It also allows companies to record the relevant details of each pallet,
parcel, and item being shipped.
Ø
Freight auditing: This will ensure that each freight bill is efficiently reviewed for accuracy. The result is
a greatly reduced risk of overpayment, and the elimination of countless hours of paperwork, or the need for a
third-party auditing firm. By intercepting duplicate billings and incorrect charges, a significant percent of
shipping costs will be recovered. In addition, carrier comparison and assignment allows for instant access to a
database containing the latest rates, discounts, and allowances for most major carriers, thus eliminating the
need for unwieldy charts and tables.
Ø
Shipping Documentation and Labeling: There will be less need for manual intervention because
standard bills of lading, shipping labels, and carrier manifests will be automatically produced; this includes
even the specialized export documentation required for overseas shipments. Paperwork is significantly
reduced and the shipping department will therefore be more efficient.
Ø
Online Shipping Inquiry: This gives instant shipping information access to anyone in the company,
from any location. Parcel shipments can be tracked and proof of delivery quickly confirmed. A customer's
transportation costs and performance can be analyzed, thus helping the customer negotiate rates and
improve service.
