  • Customer service employees help develop Web site
  • Human resource or public relations manger may
    provide Web content for employees and investors
  • Must learn about e-commerce and m-commerce
  • Many organizations use enterprise systems to
    perform business processes and to keep records
  • Support various business activities Supply chain
    management, customer relationship management

7
An Introduction to Electronic Commerce
  • Electronic commerce conducting business
    activities (e.g., distribution, buying, selling,
    marketing, and servicing of products or services)
    electronically over computer networks such as the
    Internet, extranets, and corporate networks
  • Business activities that are strong candidates
    for conversion to e-commerce
  • Paper-based
  • Time-consuming
  • Inconvenient for customers

8
Business-to-Business (B2B)
E-Commerce
  • Business-to-business (B2B) e-commerce subset of
    e-commerce where all the participants are
    organizations
  • Considerably larger and growing more rapidly than
    the business-to-consumer market

9
Business-to-Consumer (B2C) E-Commerce
  • Business-to-consumer (B2C) e-commerce customers
    deal directly with the organization, avoiding any
    intermediaries
  • Elimination of intermediaries
  • Squeezes costs and inefficiencies out of supply
    chain
  • Can lead to higher profits for companies and
    lower prices for consumers

10
Consumer-to-Consumer (C2C) E-Commerce
  • Consumer-to-consumer (C2C) e-commerce
    participants are individuals, with one serving as
    the buyer and the other as the seller
  • eBay example of a C2C e-commerce site

11
eGovernment
  • eGovernment use of information and
    communications technology to simplify the sharing
    of information, speed formerly paper-based
    processes, and improve the relationship between
    citizen and government
  • Forms of eGovernment
  • Government-to-consumer (G2C)
  • Government-to-business (G2B)
  • Government-to-government (G2G)

12
Mobile Commerce
  • Mobile commerce (m-commerce) relies on the use of
    wireless devices, such as personal digital
    assistants, cell phones, and smart phones, to
    place orders and conduct business

    global organization

Figure 5.11 Enterprise Resource Planning System
52
An Overview of Enterprise Resource Planning
  • ERP systems evolved from materials requirement
    planning systems (MRP) developed in the 1970s
  • 1980s - early 1990s organizations recognized
    that their legacy transaction processing systems
    lacked integration
  • Result higher costs and poorer customer service
  • Realization of a need for a system to coordinate
    activities and share valuable information across
    all the business functions of the firm, i.e., an
    ERP system

53
Advantages of ERP
  • Improved access to data for operational decision
    making
  • Elimination of costly, inflexible legacy systems
  • Improvement of work processes
