An information system collects, stores, and disseminates information
from an organization’s environment and internal operations
to support organizational functions and decision making, communication,
coordination, control, analysis, and visualization. Information
systems transform raw data into useful information through three
basic activities: input, processing, and output. From a business
perspective, an information system creates economic value for the
firm as an organizational and management solution, based on information
technology, to a challenge posed by the environment. The information
system is part of a series of value-adding activities for acquiring,
transforming, and distributing information to improve management
decision making, enhance organizational performance, and, ultimately,
increase firm profitability.
Information
systems are rooted in organizations; they are an outcome of organizational
structure, culture, politics, workflows, and business processes.
They are instruments for organizational change and value creation,
making it possible to recast these organizational elements into
new business models and redraw organizational boundaries. Managers
are problem solvers who are responsible for analyzing the many challenges
confronting organizations and for developing strategies and action
plans. Information systems are one of their tools, delivering the
information required for solutions. Information systems both reflect
management decisions and serve as instruments for changing the management
process. Information systems cannot make managers and organizations
more effective unless they are accompanied by complementary assets
such as new business processes, organizational culture, or management
behavior.
Information
systems literacy requires an understanding of the organizational
and management dimensions of information systems as well as the
technical dimensions addressed by computer literacy. Information
systems literacy draws on both technical and behavioral approaches
to studying information systems. Both perspectives can be combined
into a sociotechnical approach to systems.
