  1. Intranet and Internet Fundamentals Class 6Session B

  2. Topics • Intranet Concepts • Various Definitions and Views • Motivation and Business Case • Real World Examples

  3. Intranet ConceptsDefinitions “An intranet is a network of networks that is contained within an enterprise.” -- www.whatis.com “The main purpose of an intranet is to share company information and computing resources among employees. An intranet can also be used to facilitate working in groups and for teleconferences.” -- www.whatis.com “An intranet uses TCP/IP, HTTP, and other Internet protocols and in general looks like a private version of the Internet.” --- www.whatis.com

  5. Intranet ConceptsDefinitions http://www.wordmark.com/resources/pages/sem_4.html The term intranet refers to the fact that the Web (or other Internet applications) are being run completely on the inside of a private network, often without a direct connection to the Internet. There are a number of information resources and transactions that are potential candidates for an intranet… Every corporation has reams of business information that it must distribute to internal employees or external customers and suppliers.

  6. Intranet ConceptsDefinitions • Characteristics • Internet technology • TCP/IP • especially Web technology • browser as universal GUI • heterogeneity • not essential • Private • restricted access; usually behind a firewall

  7. Intranet ConceptsMotivation • Islands of Information • incompatible, proprietary file formats • expensive, incompatible viewing tools • frequent upgrading of publishing and viewing tools • massive printing budgets for documents that are rarely used

  8. Intranet ConceptsMotivation • Islands of Information (continued) • out-of-date information locked in obsolete systems • slow, long update cycles • difficult access to vital business information • redundancy and duplication of information across networks

  9. Intranet ConceptsMotivation • Better • collaboration improved quality • Faster • vital information can be had in a more timely manner • Cheaper • negligible cost to move information over long distances • technologies nearly free

  10. IntranetReal World Examples • IDC ROI Study • Amdahl • Lockheed Martin • Booze, Allen & Hamilton

  11. IntranetsReal World Examples • The IDC ROI Study • study of Netscape customers • typical ROI > 1000% • much higher than usual for IT investments • 6 - 12 week payback • implies very low risk • promises to fundamentally change way workers communicate • not since the telephone

  12. Intranets IDC Study: Calculating the ROI • H/W & S/W far less significant than personnel costs • application development • on-going support and maintenance • Web browser ease-of-use => lower training cost • typical custom application requires outside trainers and time lost in classes

  13. Intranets IDC Study: Calculating the ROI • Maintenance Costs reduced if: • if content managers identified to take lead • employees enabled through simple content generation tools • Cost Savings in areas of • paper usage • increased productivity • immediate access to information

  14. Intranets IDC Study: Calculating the ROI • 10 min/day * 3,000 employees = 30,000 employee-minutes/day = • 500 employee-hrs/day = • $25,000 / day (@ $50/hr) = • $6,500,000 / year (@ 260 working days / year) • Lower Deployment Costs • “In the morning ten people were testing it, by the afternoon 4000 people could use it!”

  15. Intranets IDC Study:Trends • Departmental Web Servers • make accessible info previously hard to access • local webmasters assist department personnel in publishing web content • Webmaster Guilds • IS from Service Organization to Coach • web technologies are personally enabling

  16. Intranets IDC Study: Summary • Intranets eliminate communication barriers • ROIs greater than 1000% common

  17. Intranet Case StudyAmdahl • Mainframe Developer • Acquisitions • double in size over short period • introduced diverse computing systems and networks • Internet technologies natural choice • Before Intranet • paper and email

  18. Intranet Case StudyAmdahl • Grassroots in 1994 • Web Council in 1995 • cross-functional • usage document • style guide • training and support • Further sub-divided into mini-Web councils

  19. Intranet Case StudyAmdahl • IS evolution • from central gatekeeper to facilitator • from centralized to decentralized / distributed application development

  20. Intranet Case StudyAmdahl • Lessons Learned • Web council provides structure, avoids bureaucracy • upper management buy-in was crucial • one-on-one tutoring of managers and secretaries • middle management overlooked • waited too long to deploy search engine • underestimated requirements of webmaster job

  21. Intranet Case StudyAmdahl • Bottom Line at Amdahl • 2063% ROI • 13 Year Payback • 3-year savings: $19 M • 3-year costs: $4.2 M
