Introduction
  • “Strategic use” of IT is defined as “having a significant, long-term impact on a firm’s growth rate, industry, and revenue.”
  • Historically, the strategic use of IT has followed an evolution from improving internal processes and structures of a firm, to improving the products, services, and relationships with its customers, and then with its partners.
  • These evolution stages are characterized as:
    • Looking inward
    • Looking outward
    • Looking across

Introduction
  • What is e-business?  The use of telecommunications networks, particularly the Internet, to conduct business transactions.
  • Three categories of e-business (see Figure 3.2):
    • Business-to-employee: Intranet-based applications internal to a firm
    • Business-to-consumer: Internet-based applications for a firm’s customers
    • Business-to-business: Extranet-based applications for a firm’s business partners
    • Originally the term e-commerce was used to refer to these three categories.  However, the term is now only used to refer to business-to-consumer applications, and the term e-business is used to refer to these three categories.

 E-Business Drivers
  • Key Components that have accelerated the acceptance of e-business:


    • Wide access to a public network
    • Standard communication protocol
    • Standard user interface


  • E-business applications run over the Internet, drastically reducing access and communications costs.
  • With standardized communication protocols and user interfaces, implementation and training costs are far lower.
  • As a result, a much broader set of users and firms has access to the systems, allowing rapid growth.

1. Looking Inward:
Business-to-Employee
  • Intranets
    • Intranets are private company networks that use Internet technologies and protocols, and possibly the Internet itself.


    • Benefits of using intranets
      • Wider access to company information
      • More efficient and less expensive systems development
      • Decreased training
6
1.1 Managing Intranets
  • Managerial concerns
    • How to integrate legacy systems into the intranet
    • Deciding how much control of the systems should be decentralized
  • Proposed solutions
    • Create a corporate portal to act as the gateway to the firm’s internal resources, information, and Internet services.
    • Develop separate departmental or divisional portals, such as sales, HR, operations, and finance portals.

2. Looking Outward:
Business-to-Consumer
  • The E-Business Model
    • Redefining Customer Value
      • “Demanding on-demand”: reduces the time it takes to respond to customer requests
      • Convenience: allows gathering and managing customer information
      • Access to a wide range of competitive prices and sellers for products

2. Looking Outward:
Business-to-Consumer
    • Redesigning Relationships with Business Partners
      • E-business allows:
        • “disintermediation”: bypassing intermediaries by directly linking customers to the manufacturer.
        • the development of “virtual organizations,” where a firm does not own parts of the value chain, but rather controls the coordination of other firms to appear as a single firm.

3. Looking Across:
Business-to-Business
  • IT has been used to reduce costs and time of interorganizational transactions, for example:
  • Interorganizational Systems (IOS)
    • Reservation systems, electronic funds transfer systems, Electronic Data Interchange Systems (EDI)
  • Electronic Data Interchange Systems (EDI)
    • Transmission, in standard syntax, of data for business transactions between computers of independent organization
10
3.1 Electronic Data Interchange
  • Goal: Eliminate paper documents involved in business transactions
  • Barriers:
    • Technology available
    • Standards/lack of standards
      • X12
      • EDIFACT
  • Value-added network (VAN): Third party companies that provide communication links and EDI services to other companies


11
3.2 Electronic Data Interchange
  • Traditional Versus Internet–Based EDI
  • Overcomes many technical barriers to EDI
    • Eliminates the need for expensive telecommunication network
    • Flexible systems
    • Multimedia documents rather than simple streams of text


12
3.3 Supply Chain Integration
  • Supply chain includes processes such as: logistics, procurement, production, and distribution


  • Strategic options
    • Build-to-order mode of operation
    • Elimination of intermediaries
    • Redesign the procurement process
13
3.4 Integration with Back-End Systems
  •  Challenge
    • Variety of platforms
    • Incompatible


  •  Approach
    • Database Management Systems (DBMS)
    • ERP Systems
    • Extranet
14
4. Technical Considerations
  • Evolution of the Internet: Quality of Service
  • Next Generation Internet (NGI)
    • Research and develop advanced network technologies
    • Deploy high-speed test bed networks
    • Develop and demonstrate revolutionary applications that demand high-speed networks not currently available on today’s internet
  • University Consortium for Advanced Internet (UCAID)
    • Internet 2 (advanced academic network)
    • Abilene (support the demands of the advanced research applications of the UCAID)
15
4. Technical Considerations
  • Security - ranks as one of the top management and consumer concerns
  • Divided into three categories:
    • 1. Sniffing: interception and reading of electronic messages as they travel over the communication networks
      • Protection: Encryption (DES, RSA)
    • 2. Spoofing: assumption of a false identity and the execution of fraudulent transactions
      • Protection: Authentication (RSA)
    • 3. Hacking: unauthorized access to a host computer
      • Protection: Firewall
16
5. Legal and Ethical Considerations
  • Privacy
  • Intellectual Property Rights
    • Copyrights
    • Patents
    • Trademarks
    • Trade Secrets
  • Legal Jurisdiction
  • Content Regulation

6. Conclusion
  • IT is a strategic asset that can be used to:
  • Look outward to incorporate products and services
  • Look inward to re-design and create new business processes
  • Look across to link with other organizations
  • make permanent changes in the nature of business with e-business
