3Introduction
- Competing effectively in high-volume e-commerce
may not be possible without the infrastructure
provided by ERP - Integrating ERP systems with the Internet is
becoming easier with new technologies like Web
services and XML - ERP systems are becoming more affordable as
smaller companies rent ERP services
4Electronic Commerce Background
- E-commerce is the conduct of business over the
internet - Most business growth on the Internet has been
business-to-business (B2B) e-commerce, rather
than business-to-consumer (B2C) e-commerce - B2B sales are expected to approach 1 Trillion in
Europe by 2006 - B2B e-commerce is transforming the way companies
work with each otherespecially for commodity
products
5Electronic Data Interchange (EDI)
- Companies have been able to transfer purchase
orders electronically since the 1960s through a
system known as Electronic Data Interchange
(EDI), originally using telephone lines - EDI networks are expensive, so many companies
subscribe to value-added networks (VAN), an
intermediary Internet-based network - EDI messages are standardized business
transactions that follow a specific computer
protocol
6Electronic Data Interchange (EDI)
- Benefits of EDI include
- Costs of paper, printing, and postage have almost
disappeared - Errors are minimized as orders are not manually
entered into the suppliers information system - Ordering is fast and efficient
- Large companies may require suppliers to use EDI,
and may pay EDI costs for small suppliers - EDI tends to lock buyers and suppliers into a
long-term relationship - An advantage as long as both parties remain
satisfied
7Internet-Based Procurement
- Internet-based procurement
- Is less expensive than private EDI networks
- Reduces purchasing costs further as suppliers
compete for orders on the buyers Web site - Locking in suppliers often does not occur in
Internet-based procurement - Internet-based procurement has led to electronic
marketplaces - Marketplaces provide advantages for both buyers
and sellers - Exchanges are B2B marketplaces that typically
focus on a single industry
8ChemConnect.com
- Buyers and sellers of chemical products can use
the ChemConnect marketplace - Buyers can find the best prices without
traditional negotiations - Contracts are completed faster between buyers and
sellers - Buyers and sellers can gain access to new
worldwide markets and trading partners - Instant market information is available to all
parties
9Private Exchanges
- Companies like Siemens, Volkswagen and IBM have
set up private exchanges - Membership is restricted to select participants
- Volkswagen has slashed procurement costs in half
and cut negotiations from three months to a day - Jupiter Research estimates that one-third of all
businesses with revenues over 1 billion will
operate private exchanges
10Internet Auctions and Reverse Auctions
- Companies can use standard auctions to sell
products or obsolete equipment - Reverse auctions, with one buyer and many
sellers, can be used to purchase commodity
products that are widely available at recognized
quality standards - Internet auctions are challenging the role
previously filled by traditional intermediaries - Epsilon Products has used ChemConnect to reduce
raw material costs by 5 - Increased competition from marketplaces creates a
new emphasis on supply chain flexibility and costs
11Electronic Commerce Security
- E-commerce is threatened by security breaches
- Large firms have been shut down by various types
of system attacks, such as denial-of-service
attacks - Denial-of-service (DoS) attacks occur when
attackers block a Web site by a variety of means,
including bombarding the system with messages - Buy.com, Amazon, CNN.com, eBay ETrade, ZDNet and
Yahoo were all shut down temporarily in February
200 because of DoS attacks - Yahoo lost approximately 500,000 from a
three-hour attack - Security is an on-going effort
12E-commerce and ERP
- E-commerce and ERP technologies are complements
- If the competition is using the Internet
effectively, then a company needs to develop an
Internet strategy - Without integrated information systems, companies
cannot support e-commerce effectively - In 1999, eToys.com announced a week before
Christmas that it would not be able to fill all
Web orders - Toys were in the warehouse, but the systems were
not in place to process orders
13Application Service Providers
- An Application Service Provider (ASP) provides
management of application programs over a network - Companies using the ASP do not have to purchase
the hardware or software or higher people to
operate systems - ASPs can also provide consulting services for
software applications like ERP - ASPs can provide access to expensive applications
like ERP with much lower startup costs

15Application Service Providers
- ASP Advantages
- Affordability Many companies that previously
couldnt afford ERP systems can now afford to
lease it through an ASP - Shorter implementation times Implementation time
is shorter because the company does not have to
purchase hardware and software and train
technical staff - Expertise ASPs are more likely to be able to
hire and retain competent technical personnel
than a small company can
16Application Service Providers
- ASP Disadvantages
- Security Companies turn their critical
information over to a 3rd party - ASP must be able to insure data integrity
- ASP may have better security and controls than a
small company - Bandwidth/response time Telecommunications
channel between ASP and company must be able to
handle volume of transactions - Flexibility The ASP must be flexible in working
with users and satisfying requests for
modifications
17Application Service Providers
- ASP Disadvantages
- No frills An ASP may not be willing to support
3rd party software or develop custom applications
(e.g. ABAP programs) - Technical, not business An ASP may know the
technical aspects of the software but may not be
capable of helping customers with business
process and configuration decisions
18Another LookUsing ERP through an ASP
- In the 1990s, Universities that joined SAPs
University Alliance program had to purchase a
server (costing over 50,000) and had to train
its own system administrators - SAP had to provide technical support for over 100
university installations - SAP developed a hosting concept known as the
University Competency Center (UCC) - Five Universities serve as ASP for other members
in the Alliance, providing customer technical
support for educationa specialized task

21NetWeaver
- Web Services is the combination of software tools
that lets various programs within an organization
communicate with other applications - NetWeaver is SAPs Web services platform
- FedEx built its package tracking system on Web
services - FedExs cost per inquiry has been reduced from
2.14 to 0.04 - Travelers Insurance Company has cut its auto
glass claim processing costs by 30 percent using
Web services
22NetWeaver
- NetWeaver is a collection of components that
supports business processes over the Internet - Modules include
- Enterprise Portal
- Mobile Infrastructure
- Business Intelligence
- Master Data Management
- Exchange Infrastructure
23NetWeaver
- Enterprise Portal (mySAP.com)
- Gives users complete access (a portal) to all
work on a single screen - A portal is a customizable Web site that links
to - Internet
- e-mail
- Calendar
- SAP R/3 system
- Other systems
- Users can access all required information with a
single sign-on - Provides drag-and-relate capabilities
24NetWeaver
- Mobile Infrastructure
- Allows users to access and work with data
through - PDAs
- Cell phones
- Pagers
- Provides access to data within SAP and other
company information systems - A partnership between SAP and VoiceObjects AG
will add voice capability to NetWeaver
25NetWeaver
- Business Intelligence (BI)
- BI incorporates data warehouse and data mining
tools - BI can be delivered in a personalized manner with
Enterprise Portal - Can integrate information from various sources
within and outside the firm - BI works with any database management software
and any operating system
26NetWeaver
- Master Data Management
- Provides data consistency within a companys SAP
system - The grocery industry could save 25 to 50
billion if suppliers could synchronize their
data, such as product numbers, with retail
outlets - Exchange Infrastructure
- Allows different applications to share data
without writing code
27Accessing ERP over the Internet
- ERP vendors offer access to their systems over
the Internet using a Web browser - Easier to administer than special-purpose GUI
software - Software upgrades are easier to administer, as
only server (and not end-user) software needs to
be upgraded
28XML
- Extensible Markup Language (XML) is the new
programming language of the Internet - XML uses tags to define the data contained in Web
pages - XML tags give specific meaning to data
- HTML only specifies how information will look on
a Web page - XML-coded data can go directly from a Web page to
a database without the need for middleware - ERP systems are now ready to accept data in XML
format

30Another LookXML, ERP and E-commerce
- OxyChem realized tremendous customer service
benefits when it linked its SAP system with a
customers SAP system - This experience caused OxyChem to embark on a
mission to link its SAP system with the
information systems of its 5,000 customers - OxyChem has developed four linking strategies
- XML-based ERP to ERP
- Physical probes in customers raw material
containers - ChemConnect Web site
- OxyChems own Web portal
31Radio Frequency Identification
- Radio Frequency Identification (RFID) technology
is becoming an efficient way of tracking items in
the supply chain - An RFID device is a small package, or tag, with a
microprocessor and antenna - Information from the RFID tag is transmitted via
radio waves to a receiver when interrogated by an
RFID reader - Does not require line-of-site contact like a bar
code reader
32Radio Frequency Identification
- Wal-Mart is driving the implementation of RFID
with its suppliers - Wal-Mart will connect RFID data with its Retail
Link system, where buyers and suppliers can check
inventory levels, sales and more - Proctor Gamble is using RFID technology to
improve demand management in its supply chain to
avoid the bullwhip effect - SAPs R/3 software is RFID ready
- With NetWeaver, SAP can link RFID with both SAP
and non-SAP systems
33Summary
- E-commerce is transforming the way companies do
business. Business-to-consumer e-commerce can
streamline a companys ordering operations and
record information about customers that can be
used to plan marketing campaigns, making the
company more competitive. - Business-to-business e-commerce is changing the
way companies buy and sell goods. New forms of
procurement such as auctions, reverse auctions,
and trading exchangesall with dynamic
pricingare replacing the traditional
intermediary. - ERP is an essential component for all forms of
e-commerce. An integrated information system is
required to provide speed and consistency in
transaction processing and other back-office
operations.
34Summary
- Application service providers (ASPs) are allowing
companies to use ERP without a large initial
investment, making ERP systems available to
smaller companies. There are risks associated
with using an ASP, however, and the decision to
buy or lease must be weighed carefully. - Web Services, a combination of software tools
that lets various programs within an organization
communicate with other applications, are gaining
popularity. - SAP's Web services platform is NetWeaver, which
includes those tools for seamless Web
connectivity, and also modules such as Business
Intelligence, Mobile Infrastructure and Master
Data Management.
35Summary
- Users of ERP systems often access those systems
through a Web browser rather than the ERP
systems' graphical user interface (GUI). - XML, extensible markup language, defines data on
a Web page. ERP systems are using XML to
integrate systems between suppliers and customers
for easy data transfer. - RFID devices, or radio frequency identification
devices, are used in tracking items in transit.
RFIDs are particularly useful in supply chain
processes for shipping and receiving cases and
pallets of items. ERP vendors are developing the
capability to incorporate RFID technology into
ERP software.
