Economics of E-Commerce
 Costs of information exchange are
dramatically reduced
 Barriers to entry are lower
 Time constraints almost disappear
 Information and communication is
cheap and easy

S11 – 12


Types of Information
 Product — drawings, specifications,
video, or simulation demonstrations,
prices
 Production Processes — capacities,
commitments, product plans
 Transportation — carrier availability,
lead times, costs
 Inventory — inventory tracking, levels,
costs, and location
Table S11.1

S11 – 13


Types of Information
 Suppliers — product catalog, quality
history, lead times, terms, and
conditions
 Supply Chain Alliances — key contact,
partners’ roles and responsibilities,
schedules
 Supply Chain Process and Performance
— process descriptions, performance
measures such as quality and delivery
Table S11.1

S11 – 14


Types of Information
 Competitor — benchmarking, product
offerings, market share
 Sales and Marketing — point of sale
(POS) data entry, promotions, pricing,
discounts
 Customer — sales history and forecasts

Benefits and Limitations
Benefits of E-Commerce
 Improved, lower-cost information that
makes buyers and sellers more
knowledgeable has an inherent power to
drive down costs
 Lower entry costs increase information
sharing
 Available 24 hours a day, virtually any
place in the world, enabling convenient
transactions for those concerned
Table S11.2

S11 – 16


Benefits and Limitations
 Availability expands the market for both
buyer and seller
 Decreases the cost of creating,
processing, distributing, storing, and
retrieving paper-based information
 Reduces the cost of communication
 Richer communication than traditional
paper and telephone communication

because of video clips, voice, and
demonstrations

S11 – 17


Benefits and Limitations
 Fast delivery of digitized products such
as drawings, documents, and software
 Increased flexibility of location. (That is,
it allows some processes to be located
anywhere electronic communications
can be established, and allows people
to shop and work from home.)

S11 – 18


Benefits and Limitations
Limitations of E-Commerce
 Lack of system security, reliability, and
standards
 Lack of privacy

 Some transactions are still rather slow
 Integrating e-commerce software with
existing software and databases is still
a challenge
Table S11.2

S11 – 19


Benefits and Limitations
 Lack of trust in (1) unknowns about the
integrity of those on the other end of a
transaction, (2) integrity of the
transaction itself, and (3) electronic
money that is only bits and bytes

Security and risk are major
factors in E-commerce

information allows quicker and lower
cost design cycles that can involve
participants in diverse locations

supply chain

one site
 Buyer-focused exchanges allow

groups of generally similar firms to
join together to buy in larger
quantities and more efficiently than
if they worked independently
