There is no new thing under the sun

Ecclesiastes, Chapter 1, Verse 9

He who forgets the past is condemned to repeat it.

Jorge Santayana


Evolutionary Perspectives & Industry Comparisons

But first…..Let’s put everything into perspective.

ECT 481 16

"Let us not forget that the value of this great system does not lie primarily in its extent or even in its efficiency. Its worth depends on the use that is made of it.…….For the first time in human history we have available to us the ability to communicate simultaneously with millions of our fellowmen, to furnish entertainment, instruction, widening vision of national problems and national events. An obligation rests on us to see that it is devoted to real service and to develop the material that is transmitted into that which is really worthwhile."

Who said this? Bill Gates? Newt Gingrich? Al Gore? Alvin Toffler?

An Interesting Quote

ECT 481 17

Perspective on the Internet, Ecommerce and Earlier Technology Innovations

Internet is a change agent in global commerce.

There have been comparable periods of industrial change.

Internet and Ecommerce evolution & expansion is similar when compared and contrasted with:

railroad, telegraph, telephone, and radio.

In all cases, early pioneers (practitioners, inventors, etc.) knew they were on to something.

ECT 481 18


Parallels between the evolution of telegraph, radio, and the Internet.

• Each transmits intangible items (i.e., information).• Each shortened the time to transfer info.• Their utility (i.e., their ability to deliver products & services) is dependent on the efficacy and efficiency of their underlying network. • All had initial usability, training, & infrastructure problems.• All have or are experiencing the S-curve in lifecycle product development.

ECT 481 19

Discussion Objectives

• Establish a discussion context regarding Ecommerce & B2B marketplaces.

• Discuss historical and market perspective for the evolution of Ecommerce & B2B marketplaces.

ECT 481 21

Discussion Baseline: Terminology Defined

• Electronic Commerce or E-commerce - the conduct of a financial transaction by electronic means; more recently, the purchase of goods and services over the Internet’s World Wide Web. Includes the following types:

• Business-to-Business or B2B E-commerce - inter-organizational E-commerce

• Business-to-Consumer or B2C E-commerce - electronic commercial interaction between the enterprise and the end consumer.

• Business-to-Employee or B2E E-commerce- intra-organizational E-commerce.


ECT 481 22

Distinguishing B2B & B2C

B2B E-commerce is the exchange of products, services, or information between businesses rather than between businesses and consumers.

e-Business. Suppliers and ‘Big C’s’ - transactions between businesses. Focus on transaction efficiency.

B2C E-commerce the retailing of goods and services directly to end consumers via the Internet.

Suppliers & ‘little C’s – transactions between goods and service providers and end consumers.

Dis-intermediation. (theoretically) lowers inventory and distributions costs.

ECT 481 23

Electronic Data Interchange (EDI) defined:

EDI – Inter-company, computer-to-computer communication of data which permits the receiver to perform the function of a standard business transaction and is in a predefined standard format.

Enabled ‘Old-school’ B2B E-commerce. It still works.

Enables electronic intra-company exchange of purchase orders and other transaction documents.

EDI based on standards-based protocols.

ECT 481 24

Distinguishing Intranet & Extranet

Intranet defined An intranet is a corporate LAN or WAN that functions with Internet

technologies behind the company’s firewall.

Extranet defined An extranet is a network that links the intranets of business partners using

a virtually private network on the Internet. Designing extranets is difficult. Complexities of security, performance, management and policy.

Extranet and B2B are not synonymous. Extranets can apply to B2C as well.

ECT 481 26

Brief History of E-commerce and B2B marketplaces.• E-commerce and B2B are not new concepts.

• Current systems emanated more directly from Electronic Data Interchange (EDI).

• EDI provides for the exchange transaction information over proprietary Value-Added Networks (VAN’s).

•EDI participants realized benefits such as:

• reduction in process costs, and

• enhanced profitability.

• EDI participants also incurred significant expenditure in

• EDI deployment costs, VAN charges.

• EDI limited to a few very large & wealthy organizations.

Enter the Internet, B2B Marketplaces & Internet-based EDI!

•B2B extranet system deployment on the rise.

• Third-party B2B Market Makers are key movers in evolution of internet-based ‘EDI’.

.

How is B2B conducted?

B2B commerce can be conducted directly between a buyer and seller or via an online intermediary. The intermediary can be:

• a person or • an organization or • an electronic system

What are the types of transactions?

• Spot Buying • buying goods and services at market prices • often facilitated by a third party exchange

• Strategic Sourcing • long-term contracts that are usually negotiated to get a good cost advantage • often this is done by streamlining your supply chain

B2B Electronic Commerce Key Characteristics

So what should we expect?

• Currently experiencing re-vitalization (post recession).• E-commerce has become mainstream and internalized by “old economy” firms.• B2B uptake will continue with improved economy, probably tied to supply chain management improvements.• A number of small technological, micro-improvements will impact the E- commerce and the internet over the short-term.• “Last-mile” infrastructure improvements (ubiquitous broadband) has had significant impact on level of internet usage.• Security will continue to be of paramount concern and will garner significant expenditure. An outstanding area of entrepreneurial opportunity.

ECT 481 38

B2B Critical Success Factors

• Plenty of buyers and sellers – you need both to make a market.

• Liquidity – value of a market make r is a multiple of the value of the transactions flowing through it; market makers (MM’s) must be focused on generating industry-leading liquidity.

• Fragmentation – MM’s add most value in highly fragmented markets.

• Inefficiency – MM’s must add value to both sides of the trade.

• Management with domain expertise – senior-level industry relationships and creditability facilitate industry ‘buy-in’.

• Early mover advantage – Ebay only had a year head start in the C2C auctions business, but that was enough.

• Partnerships for distribution and logistics – UPS doesn’t transport lumber, resin, or HCL acid.

• Neutrality – few business opt to do business with their competitors or with subsidiaries of competitors; do not sacrifice liquidity to gain neutrality.

• Public currency – with a billion dollar market cap, if you don’t yet have a real business, then go and buy one; in the end, real value/dollars count.

ECT 481 39

Key Technology

Key Ecommerce technology architecture components include the following: web browsers application servers secure file transfer servers customer account management systems remote administration tools directory servers authentication systems commerce systems distributed computing infrastructures and databases messaging systems & middleware firewalls and proxies security scanners

ECT 481 40

Remaining Mission Critical Terms

Business Process Re-engineering (BPR) - fundamental rethinking and radical redesign of business processes to achieve dramatic improvements in critical performance measures such as cost, quality, service, speed.

Security – the combination of technology and policies designed to protect sensitive business information and to prevent fraud.

Firewall – a security screen placed between an organization’s internal network and the external Internet.

Virtual Private Network – a wide-area network (WAN) created to link a company with external users (including mobile users, field representatives, or strategic allies).

ECT 481 41

Evolving B2B Trends: XMLXML (Extensible Markup Language)

• enables sharing of interactive documents across the Internet.

• offers format for representing data, a schema for describing data, and means for extending HTML.

• Key to transition from traditional EDI to Internet-based EDI.

• Processes most affected have been order fulfillment, production, logistics, and inventory.

• Electronics industry has taken the lead in XML use in the supply chain.

• Toshiba, Solectron, Intel, Ingram Micro , American Express, Federal Express, and Cisco are key practitioners.

ECT 481 42

Supply Chain Considerations

What is the ‘Supply Chain’? All organizations and processes related to products and services sourced by

Buying Organizations, typically from raw materials through consumption.What is ‘Supply Chain Management’?

Supply Chain Management (SCM) is the management of all activities along the supply chain; from suppliers to internal logistics within a company and to distribution to customers.

Contrasted with the Value Chain Value chain is a series of activities a company performs to achieve its goal by

adding additional values as each activity proceeds to the next one. The value chain looks at every step in the supply chain management process -

from source materials to delivery of the final product to the customer. The objective of the value chain is maximum value (to the customer) at the least

possible cost (to the business). The supply chain focuses on getting source materials into manufacturing

operation smoothly and economically.

SCM Success Factor: Effective and Timely Information Management

Successful SCM often times tied to coherent information technology strategy and appropriate architecture. information systems that diffuse organizational boundaries.

Supply chain links suppliers, distributors, buyers, assemblers, etc. as virtual organization

Embraces concept of the Inter-organizational Information Systems (IOIS)

Systems that cross organizational boundaries. Requires technology that enables electronic link between organizations. Automates manual and paper-bound work. Earliest forms of these systems were time-sharing services, online

databases, EFT, EDI.
