INFORMATION MANAGEMENT: AN OVERVIEW
Management of information systems is a core business activity that can no
longer be given to technical personnel
Information manager- responsible for activities needed to generate, analyze, and
publicize 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
To find the info they need to make critical decisions, managers often sift through
a virtual avalanche of reports, memos, magazines, and phone calls
Data versus Information
Data- raw facts and figures (Ex: 5 million tubes of toothpaste were sold last year)
Information- 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
1. Determine what info is needed
2. Must gather the data and apply the technology to convert data into info
3. Control the flow of info so that it goes only to those people who need it
Supplied info varies according to such factors as the functional areas in which
people work and their management levels
NEW BUSINESS TECHNOLOGIES IN THE INFORMATION AGE
Employees at every level in the organization uses IS to improve performance
(Ex: scheduling, evaluating, and formulating)
Widening role of IS results from rapid developments in electronic technologies
that allow faster and broader flows of info and communications
