New Business Technologies in the Information Age
- Electronic Business and Communications Technologies:
Electronic information technologies (EIT): IS applications based on telecommunications technologies. EITs enhance the
performance and productivity of general business activities by performing two functions: providing coordination and
communication within the firm, and speeding up transactions with other firms.
- Six types of EIT:
Fax machine (facsimile machine): a machine that can quickly transmit a copy of documents or graphics over telephone
Voice mail: A computer-based system for receiving and delivering incoming telephone calls.
Electronic mail (email) system: electronic transmission of letters, reports, and other information between computers.
Electronic conferencing: allows people to communicate simultaneously from different locations via telephone, video or
email group software.
Groupware: a system that allows two or more individuals to communicate electronically between desktop PCs.
- Data Communication Networks:
Data communication networks: global networks that permits users to send electronic messages quickly and
Internet: A gigantic network of networks that serves millions of computers, offers information on businesses, science,
and government, and provides communication flows among more than 170,000 separate networks around the world.
Internet service provider (ISP): A commercial firm that maintains a permanent connection to the internet and sells
temporary connections to subscribers.

New Options for Organization Design: The Networked Enterprise:
- Leaner organizations:
Information networks leading to leaner companies with few employees and simpler organizational structures.
Since today’s networked form can maintain information linkages among both employees and customers, more work can
be accomplished with fewer people.
Widespread reductions in middle-management positions and the shrinkage of layers in organizational structure are
possible because information networks now provide direct communications between the top managers and workers at
Electronic information networks are replacing the operating managers who formerly communicated company policies,
or work instructions to lower-level employees.
- More flexible operations:
Mass customization: producing large volumes of products or services, but giving customers the choice of features and
options they want.
- Increased Collaboration
Collaboration not only among internal units but with outside firms as well, is on the rise because networked systems
make it cheaper and easier to contact everyone, whether other employees or outside organizations.
Aided by intranets, more companies are learning that complex problems can be solved better by means of collaboration,
either in formal teams or through spontaneous interactions.
In the new networked organization, decisions that were once the domain of individuals are now shared as both people
and departments have become more interdependent.
- Networking and the Virtual Company:
Networked systems can also improve collaboration between organizations through the so-called virtual company.
This can be a temporary team assembled by a single organization, but a virtual company can also be created by several

for any one of them working alone.
- Greatest Independence of Company and Workplace:
Geographic separation of the workplace from the company headquarters is more common than ever because of
