  5. 5. The Internetworked E-Business Enterprise <ul><li>Businesses have become internetworked E-business enterprises . The Internet & Internet-like networks :- </li></ul><ul><ul><li>inside the enterprise ( intranets ), </li></ul></ul><ul><ul><li>between an enterprise & its trading partners ( extranets ), and </li></ul></ul><ul><ul><li>and other types of networks </li></ul></ul><ul><li>are now the primary IT infrastructure of many organisations. </li></ul>
  6. 6. The Internetworked E-Business Enterprise (cont’d) <ul><li>Benefit : </li></ul><ul><li>The Internetworked E-business enterprise enables managers, business professionals, teams, & workgroups to electronically exchange data & information anywhere in the world with other end users, customers, suppliers, and business partners. </li></ul>
  7. 7. E-Business <ul><li>is defined as the use of Internet technologies to internetwork and empower business processes , electronic commerce , and enterprise communications and collaboration within a company and with its customers, suppliers, and other business stakeholders. </li></ul>
  8. 8. E-Business Applications Enterprise Communication and Collaboration Enterprise Communication and Collaboration Electronic Business Applications Telecommunications Networks Electronic Commerce Internal Business Systems The Internet Intranets Extranets
  9. 9. <ul><li>One of three major categories of E-business applications is Enterprise Communication and Collaboration . </li></ul><ul><ul><li>These are applications that support real-time global communication and collaboration between employees, customers, suppliers, and other business partners. </li></ul></ul><ul><ul><li>Examples of these applications include E-Mail , chat systems , audio & videoconferencing , and electronic meeting systems . </li></ul></ul>E-Business Applications (cont’d)
  10. 10. Objectives <ul><li>Describe how intranets & extranets are used for communications & collaboration in an enterprise </li></ul><ul><li>Describe the concept of an Enterprise Collaboration System and identify its components </li></ul>
  11. 11. What is an intranet ? <ul><li>An intranet is a network inside an organization that uses Internet technologies such as web browsers, TCP/IP network protocols, and HTML to provide an Internet-like environment within the enterprise for information sharing, communication, collaboration, and support of business processes. </li></ul><ul><li>Access to an intranet is protected by such security measures as passwords, data encryption and fire walls and thus, can only be accessed by authorized users , including business customers and partners who may access the intranet via their own intranet or through extranet links. </li></ul>
  12. 12. Applications of Intranets Communicate and Collaborate with E-mail, chat, conf. Communication and Collaboration Secure, universal access. To view corporate data Author, publish and share hypermedia documents Centrally administer clients, servers, security, and traffic Business Operations and Management Web Publishing Intranet Portal Management F I R E W A L L Internet Extranet Customers, Suppliers Enterprise Portal Existing E-Mail Voice Mail Systems Existing Database and Enterprise appl. HTML, MS Office XML, Java Existing Hardware and Networks
  13. 13. Enterprise Information Portal (EIP) <ul><li>An EIP is a web-based interface that gives intranet users and selected extranet users access to a variety of internal and external business applications and services. </li></ul><ul><li>The portal provides users with a easy means for accessing key corporate resources. </li></ul>
  14. 14. EIP (cont’d) <ul><li>Examples of internal applications might include: </li></ul><ul><ul><li>Access to E-mail, project websites, & discussion groups </li></ul></ul><ul><ul><li>Human resources web self-services </li></ul></ul><ul><ul><li>Customer, inventory, & other corporate databases </li></ul></ul><ul><ul><li>Decision support sys., & knowledge management sys. </li></ul></ul><ul><li>Examples of external applications might include: </li></ul><ul><ul><li>Industry, financial, & other Internet news services </li></ul></ul><ul><ul><li>Links to industry discussion groups </li></ul></ul><ul><ul><li>Links to customer & supplier Internet & extranet websites. </li></ul></ul>
  15. 15. EIP: Benefits <ul><li>Together with intranets, EIPs provide an organisation with: </li></ul><ul><li>Increased productivity through quick, low-cost access to key business information. </li></ul><ul><li>Easier and less costly information development, distribution, and publication through use of web-publishing technologies. Such technologies allow hyperlinked documents to be ‘pushed’ to workgroup members wherever they are. </li></ul><ul><li>Enhanced cross platform integration and deployment of core information systems. Such systems may interface with legacy systems, allowing employees and business partners to access such applications anywhere, anytime. </li></ul>
  16. 16. Intranet Technology Architectures Management Security Software Tools Content and Data Infrastructure TCP/IP Network Hypermedia Databases Servers Browsers Network Management Software Authoring Tools Policies and Standards Firewalls Passwords Encryption
  17. 17. <ul><li>Intranets and other Internet-like networks within organisations are not without their costs. </li></ul><ul><li>They must invest in the software tools like authoring software, needed to develop web-based content, and the security devices , like fire walls, and encryption software needed to protect information assets. </li></ul><ul><li>Lastly, these data resources must be managed. This includes developing the policies and standards needed to guide development and publication of web content, and determining who may gain access to specific content. </li></ul><ul><li>Management also includes management of network resources , including such functions as monitoring input and output activities, assigning priorities to data communication requests, planning for new business needs, detecting and correcting transmission errors and handling other network problems. </li></ul>Intranet Technology Architectures (cont’d)
  18. 18. <ul><li>Intranets can significantly improve communications & collaboration within an enterprise. Examples include: </li></ul><ul><li>Using an intranet browser and PC or NC workstation to send & receive E-mail, voicemail, paging, & faxes to communicate with others within your organisation, & externally through the Internet & extranets. </li></ul><ul><li>Using intranet groupware features to improve team & project collaboration with services such as discussion groups, chat rooms, & audio & videoconferencing. </li></ul>Intranet Improve Communications & Collaboration
  19. 19. The Role of Extranets
  20. 20. <ul><li>An extranet is a network that uses Internet technologies to interconnect the intranets of its customers, suppliers, or other business partners. </li></ul><ul><li>Extranets allow companies to: </li></ul><ul><ul><li>access customer and supplier information easier and faster </li></ul></ul><ul><ul><li>offer new and enhanced kinds of interactive services to business partners, and more importantly </li></ul></ul><ul><ul><li>form strategic alliances with customers, suppliers, business partners and even competitors </li></ul></ul><ul><ul><li>enable companies to form virtual corporations that in turn allow business partners to take advantage of market opportunities that they would not be able to pursue individually. </li></ul></ul>The Role of Extranets (cont’d)
  21. 21. <ul><li>Intranets & extranets support realtime global communications & collaboration among employees, customers, suppliers, & other business partners. </li></ul><ul><ul><li>Interactive web sites , E-mail , chat systems , discussion groups , audio- & videoconferencing , and other Internet features enable internal and external business information to be researched, solicited, disseminated, and shared. </li></ul></ul><ul><ul><li>Members of different organisations and people at different locations are able to work together as members of virtual teams on business projects to develop, produce, market, and maintain products and services. </li></ul></ul>Enterprise Communications & Collaboration
