Information systems in organizations include systems that:
a. Support business operations of the firm
b. Support its management
c. Assist general knowledge work (work with abstract information rather than with tangible materials).
Information systems include:
1. Transaction Processing Systems: Necessary for operational data processing.
2. Management Reporting Systems: Capable of producing reports for specific time periods, designed for managers responsible for specific functions or processes in a firm.
3. Decision Support Systems: Designed for the support of individual and collective decision making.
4. Executive Information Systems: Support the long-term strategic view that senior executives and company boards need to take of the business.
5. Professional Support Systems: Support performance of tasks specific to a given profession.
6. Office Information Systems: Support and help coordinate knowledge work in an office environment by handling documents and messages in a variety of forms - text, data, image, and voice.
Information systems of an organization can become connected to those of its suppliers, customers, and business partners, or to the providers of information about the external environment in which the firm operates. All of these are increasingly connected into interorganizational systems that help several firms share information in order to coordinate their work, collaborate on common projects, or sell and buy products and services.
A strategic information system assists a firm in realizing its long-term competitive goals.
The implementation of information systems in an organization should pay for themselves in business results.
1. Enhanced competitive position (increased market shares or profits
2. Increased productivity (lower costs per unit of output.
3. Improved quality of products or services leading to higher customer satisfaction.
4. Improved decision-making ability.
5. Ability to respond faster to the demands of the marketplace.
6. Enhanced ability to communicate and collaborate within the firm and with customers and suppliers.
7. Enhanced goodwill of employees
