Intranet and Internet Fundamentals
  • Class 6Session B

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

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. ---

Intranet ConceptsDefinitions

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.

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  • out-of-date information locked in obsolete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 gt 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 gt 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 (_at_ 50/hr)
  • 6,500,000 / year (_at_ 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 StudyTrends
  • 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
