Chapter 3 – Managing Information Systems and Communication Technology
Information Management: An Overview
Terms:
Information manager: the manager responsible for the activities needed to generate, analyze and disseminate information
that a company needs to make good decisions.
Information management: an internal operation that arranges the firm’s information resources to support business
performance and outcomes.
- Data versus Information:
Data: raw facts and figures.
Information: a meaningful, useful interpretation of data.
- Information systems:
Information systems (IS): an organized method of transforming data into information that can be used for decision
making.
Example: text, format, commands word processor finished document
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
lines.
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
economically.
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.
World Wide Web: A system with universally accepted standards for storing, retrieving, formatting and displaying
information on the Internet.
Web servers: dedicated workstations – large computers – that are customized for managing, maintaining and supporting

websites.
Browser: software that enables a user to access information on the web.
Directories: features that help people find the content they want on the web. The user types in key words and the
directory retrieves a list of websites with titles containing those words.
Search engine: software for searching web pages that does not pre-classify them into a directory.
Intranet: A company’s private network that is accessible only to employees via entry through electronic firewalls.
Firewall: Hardware and software security systems that ensure that internal computer systems are not accessible to
outsiders.
Extranet: A network that allows outsiders limited access to a firm’s internal information system.
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
lower levels.
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
allied firms.
Each contributes different skills and resources that collectively result in a competitive business that wouldn’t be feasible
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
networked organizations.
