Part 1 - Using the Internet as a business tool
and to streamline operations (6.1 - 6.2)

The Internet - a refresher
• “Network of networks”
• Relies on common standards, e.g., TCP/IP
• Two principal developments led to popularity:
1. Commercial traffic
2. World Wide Web and GUI browsers
Part 1 - Using the Internet as a business tool
and to streamline operations (6.1 - 6.2)
Evaluate the use of the Internet as a business tool for
organizations
• The Internet may be an organization’s only public
presence and the organization may exist only on,
and because of, the Internet.
• Most organizations use the Internet to support
existing business practices and processes.
Part 1 - Using the Internet as a business tool
and to streamline operations (6.1 - 6.2)
Advantages
• Expand an organization’s reach and markets
• Support multiple ways of communicating both
internally and externally
• Support or replace different business practices
• May be a cost effective way for organizations to
use the infrastructure already in place
• Levels the playing field
Part 1 - Using the Internet as a business tool
and to streamline operations (6.1 - 6.2)

Disadvantages
• Cannot replace “the personal touch”
• Still suffers from a lack of consumer trust
especially around security and privacy
• Not a solution for bad business practices or
processes
Part 1 - Using the Internet as a business tool
and to streamline operations (6.1 - 6.2)

• Legal issues around content, product liability,
and copyright
– Legal systems need to catch up
– Jurisdiction issues
• Traffic and reliability issues
Part 1 - Using the Internet as a business tool
and to streamline operations (6.1 - 6.2)

Majority of people in the world do not have
Internet access (only about 15%)
– The “pure play” market leaves out many
people, even in developed countries
Part 1 - Using the Internet as a business tool
and to streamline operations (6.1 - 6.2)
Socio-economic impact of the “Digital Divide”
– Lack of access caused by:
- Financial constraints
- Lack of technical knowledge
- Lack of infrastructure
- Language issues
- Choice or a lack of interest or trust
– Concern over economic and social
disadvantage
– “Digital divide” is widening
Part 1 - Using the Internet as a business tool
and to streamline operations (6.1 - 6.2)
Analyze the ways in which the Internet streamlines
business operations
• Internet tools, such as email and instant
messaging can improve communications
• Centralized data and improved access
• Using websites to off–load customer data entry
and reduce the need for physical sites (such as online
banking and electronic tax filing)
Part 2
Technologies to support
groups and group work
Topic 6.3
Part 2 - Technologies to support groups and
group work (6.3)
Compare the different types of group support
technologies used by businesses and the
situations they support .
Group support technologies
• Allow coworkers and workgroups to:
– Communicate (publishing, information sharing)
– Collaborate (tracking feedback and version
control)
– Co-ordinate (scheduling and notification)
• Local or distant; synchronous or asynchronous
Part 2 - Technologies to support groups and
group work (6.3)
Local synchronous
• Real time, same place
Local asynchronous
• Individually different times, but same physical
location
Distant synchronous
• Same time, but in different physical locations
Distant asynchronous
• Individually different times and in different
physical locations

Knowledge management
• Knowledge is power
• Better knowledge management leads to
competitive advantage:
– Manage information overload
– Reduce dependence on key employees
Part 2 - Technologies to support groups and
group work (6.3)
Groupware technology can support knowledge
management by recording explicit knowledge
  and
making it available to people in different places
and at different times.
• Groupware tools for knowledge management:
– Knowledge repositories
– Knowledge maps
– Blogs, forums, etc.
Part 3
Intranet and extranet
Topic 6.4
Part 3 - Intranet and extranet (6.4)

Distinguish between an intranet and an extranet and
assess the advantages and disadvantages of each
Intranet
• Private network, created and controlled by a single
organization
• No access for people outside of the organization
• Uses the same protocols and software of the
Internet
Part 3 - Intranet and extranet (6.4)

Organization is responsible for content and
maintenance
• Common content (intranet):
– Employee orientation and training
– Company policies
– Administration/HR forms
– Resources; meeting minutes; presentations
– General information to be shared
– Company press releases
– Knowledge management resources
Part 3 - Intranet and extranet (6.4)

Extranet
• Created and controlled by a single
  organization
• Uses the same protocols and software of the
Internet
• Private network, but access is given to certain
external groups, such as suppliers or strategic
partners
Part 3 - Intranet and extranet (6.4)

Common content (extranet):
– Company press releases
– Information for partners that would not be
released to the general public
– Shared resources
Part 3 - Intranet and extranet (6.4)

Advantages of Intranets and Extranets
• Cost-effective - uses readily available tools
  that most
people already know how to use
• Easy to publish and share information
• Easy to maintain because information is in
  one
location or a small set of locations
Part 3 - Intranet and extranet (6.4)

Scalable applications - easy to add users or
  system
functionality
• Can be developed incrementally
• Easy monitoring - allows determination of
  what
content is being accessed, by whom, how, and
  when
Part 3 - Intranet and extranet (6.4)

Disadvantages of Intranets and Extranets
• Content maintenance is on-going and requires
more resources as it evolves
• Extranets are potential security risk because
they allow people external to your organization
to have access to your network
• Tools are not as sophisticated as proprietary
tools like Lotus Notes, especially around data
replication and connections
Part 3 - Intranet and extranet (6.4)

Potential for lack of integration with other
internal systems:
– Lack of integration tools
– Security concerns
• Internet standards and software are evolving:
– Current design and coding styles may go out
of fashion
– As a baseline stick to open standards
Part 4
Strategic uses of
Internet technologies
Topic 6.5
Part 4 - Strategic uses of Internet
technologies (6.5)
Evaluate how the Internet contributes to cost reduction,
differentiation, customer lock-in, strategic
alliances, and the ways it supports the value chain
of an organization
How Internet technologies can support strategy
• Reducing costs by streamlining processes and
operations:
– Improved communications
– Reducing duplication through data centralization
– Offloading data entry to customers
Part 4 - Strategic uses of Internet
technologies (6.5)
Contributing to differentiation of products by
enhancing existing products or offering new
products
• Making it easier to create and maintain
   strategic
alliances - particularly through extranets
• Increasing the loyalty of customers by
   customizing
pages based on past visits to the website
Part 4 - Strategic uses of Internet
technologies (6.5)
Supporting the value chain
• Enhancing the sales function of an
  organization
• Streamlining links between value chain
  activities
• Adding value to processes, such as linking
suppliers to the manufacturing function to
automate parts ordering
Part 4 - Strategic uses of Internet
technologies (6.5)
Obtaining the benefits of Internet technologies
• Understanding the organization’s needs and
strategies must precede the process of developing
strategic uses of the Internet
• Integration is needed to improve benefits and
reduce costs, but security is critical
• Adhering to open standards is required to take
advantage of the evolving Internet
• Ensure that you pursue an evolutionary (not
revolutionary) learning strategy
