Chapter 3 Managing Information Systems and
Communication Technology
INFORMATION MANAGEMENT: AN OVERVIEW
-Managers now turn to digital technology as an integral part of organizational
resources and as a means of conducting everyday business.
-Information manager is the manager responsible for the activities needed to
generate, analyze, and disseminate information that a company needs to make good
decisions.
-Information management is an internal operation that arranges the firms
information resources to support business performance and outcomes.
Data Versus Information
-Data is raw facts and figures.
-Information is a meaningful, useful interpretation of data.
Information Systems
-Information system is an organized method of transforming data into information
that can be used for decision making.
-IS managers must first determine what information is needed. Then they must
gather the data and apply the technology to convert data into information. They
must also control the flow of information so that it goes only to those people who
need it.
-Information quality depends on an organizations technological resources and on the
people who manage them.

NEW BUSINESS TECHNOLOGIES IN THE INFORMATION AGE
-Information systems assist in scheduling day-to-day vehicle trips, evaluating
prospective employees, and formulating the firms business strategy.
-Technology has inspired new organizational designs, innovative relationships with
other organizations, and new management processes for improved competitiveness.
The Expanding Scope of Information Systems
-Managers soon began using IS systems not merely to solve technical problems, but to
analyze management problems, especially for control purposes–applying quality-
control standards to production, comparing costs against budgeted amounts, keeping
records on employee absences and turnover.
-Information systems are also crucial in planning.
-A basic change in organizations is an increased interdependence between a
company’s business strategy and its IS.
Electronic Business and Communications Technologies
Electronic Information Technologies
-EIT are IS applications based on telecommunications technologies.
-EITs use networks of appliances or devices to communicate information by electronic
means.
-EITs enhance the performance and productivity of general business activities by
performing two functions:
oProviding coordination and communication within the firms
oSpeeding up transactions with other firms
Data Communication Networks
-Data communication networks are global networks that permit users to send
electronic messages quickly and economically.
The Internet

offers information on business, science, and government, and provide communication
flows among more than 170,000 separate networks around the world.
-The internet has become the most important email system in the world.
-Internet service provider (ISP) is a commercial firm that maintains a permanent
connection to the internet and sells temporary connections to subscribers.
The World Wide Web
-The World Wide Web is a system with universally accepted standards for storing,
retrieving, formatting, and displaying information on the internet.
-The person responsible for maintaining an organizations website is usually called a
webmaster.
-Web servers are dedicated workstations that are customized for managing,
maintaining, and supporting websites.
-Browser is software that enables a user to access information on the web.
-Directories are 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 is software for searching webpages that does not pre-classify them
into a directory.
Intranets
