for running and managing a business today?

for conducting business. Information systems are the foundation of the fast-paced supply
chains. The Internet allows many businesses to buy, sell, advertise and solicit customer
feedback online. Organizations are trying to become more competitive and efficient by
digitally enabling their core business processes and evolving into digital firms. The Internet

selling goods on global scale. New information system trends include the emerging mobile
digital platform, big data and cloud computing.

1.2 What is an information system? Hoes does it work? What are its management,
organization and technology components? Why are complementary assets
essential for ensuring that information systems provide genuine value for
organizations?
From a technical perspective 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 provides a solution to problem or
challenge facing a firm and represents a combination of management, organization and
technology elements. The management dimension of information systems involves issues
such as leadership, strategy and management behavior. The technology dimension consists
of computer hardware, software, data management technology and
networking/telecommunications technology (including the Internet). The organization
dimension of information systems involves issues such as the organization’s hierarchy,
functional specialities, business processes, culture and political interest groups.
In order to obtain meaningful value from information systems, organizations must support
their technology investments with appropriate complementary investments in organizations
