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: raw facts and figures (ex. -fifty million tubes of toothpaste were sold last year. -the birth
rate is rising slowly. - a major dentists' group recently came out in favour of brushing three times
a day.)
Information: a meaningful, useful interpretation of data (if all these data examples above can be
put together in a meaningful way, they may produce information about what sells toothpaste
and whether manufacturers should build new plants)
o The challenge for businesses is to turn a flood of data into information and to manage that
information to their best advantage
o One response to this challenge has been the growth of the information system (IS)an
organized method of transforming data into information that can be used for decision making
o Employees at every level in the organization, ranging from operational specialists to the top
executive, use information systems to improve performance
o The relationship between information systems and organizations is amongst the fastest-
changing aspects of business today. At one time, information system applications were narrow
in scope and technically focused. But then managers soon began using IS not merely to solve
technical problems, but to analyze management problems, especially for control processes
applying quality-control standards to production, comparing costs against budgeted amounts,
keeping records on employee absences and turnover.
Today, IS are also crucial in planning.
Finally, another basic change in organizations is an increased interdependence between a
company's business strategy and its IS. Today, the choice of a business strategy requires and
information system that can support that strategy. To effectively support a strategy, the
system's software, hardware, and other components must be integrated
o New electronic information technologies and more advanced data communication networks are
meeting the needs of certain companies
Electronic information technologies (EIT): are IS applications based on telecommunications
technologies
--EITSs use networks of appliances on devices to communicate information by electronic means.
EITs enhance the performance and productivity on general business activities by performing two
functions:
1. Providing coordination and communication within the firm
2. Speeding up transactions with other firms
--six of the most widely used innovations in today's digital business systems are as follows:
1. Fax machine (short for facsimile machine): a machine that can quickly transmit and receive a
copy of documents/graphics over telephone lines in a matter of seconds (thus permitting

written communication over long distances)
--popular with both large and small firms because of speed and low cost
2. Voice mail: a computer-based system for receiving and delivering incoming telephone calls.
--incoming calls are never missed because a voice responds to the caller, invites a message, and
stores it for later retrieval. A company with voice mail networks each employee's phone for
receiving, storing, and forwarding calls
3. Electronic mail (or email) system: electronic transmission of letters, reports, and other
information (graphics and videos) between computers
--email thus substitutes for the flood of paper and telephone calls that threatens to engulf many
offices
4. Electronic conferencing: allows people to communicate simultaneously from different
locations via telephone, video, or email group software
--becoming popular because it eliminates travel and thus saves money. It is also increasingly
accessible and speeds up information flows.
--one form of electronic conferencing, data conferencing, allows people in remote locations to
work simultaneously on the same document. Another form of electronic conferencing,
videoconferencing, allows participants to see one another on a video screen while the
teleconference is in progress
5. Groupware: a system that allows two or more individuals to communicate electronically
between desktop PCs
--collaborative work by teams other groups is facilitated by groupwaresoftware that connects
members of the group for email distribution, electronic meetings, message storing,
appointments and schedules, and group writing
o Commercial digital information services provide online information for both special-purpose and
general topics
Data communication networks: global networks that permit users to send electronic messages
back and forth quickly and economically
o Networks include the internet (largest public data communications network) and the world wide
web
Internet: a gigantic network of networks that serves millions of computers, offers information
on business, science, and government, and provides communication flows among more than
170,000 separate networks around the world
--allows personal computers in any location to be linked together. The internet has gained in
popularity because it is an efficient tool for information retrieval. Because it can transmit
information quickly and at low cost, the internet has also become the most important email
system in the world
o Although individual cannot connect directly to the internet, for small monthly usage fees they
can subscribe to the internet via an internet service provider (ISP): a commercial firm that
maintains a permanent connection to the internet and sells temporary connections to
subscribers
