Information is a vital part of every managers job.
For information to be useful, it must be accurate, timely, complete, and accurate.
Information technology is best conceived of as part of the control process.
Information technology systems contain five basic components. These are an
input medium, a processor, an output medium, a storage device, and a control
system. Although the form will vary, both manual and computerized information
systems have these components.
An organizations information technology needs are
determined by several factorsmost notably, user groups and systems
requirements. There are several basic levels of information systems, including
transaction-processing systems, systems for various types of workers, basic
management information systems, decision support systems, and executive support
systems, as well as artificial intelligence and expert systems. Each provides
certain types of information and is most valuable for specific types of managers.
Each should also be matched to the needs of user groups.
Managing information systems involves five basic elements.
The first is deciding how to create information systems. Of course, this step
actually involves a wide array of specific activities and steps. The systems
must then be integrated. Managers must also be able to use them. Information
security is also an important consideration in managing information systems.
Finally, managers should be aware of the limitations of information systems.
Information systems have an impact on organizations in
a variety of ways. Major influences include leaner organizations, more flexible
operations, increased collaboration, more flexible work sites, improved management
processes, and changed employee behaviors.
