In a broad sense, the term Information Systems (IS) refers to the interaction between people, processes, and technology. This interaction can occur within or across organizational boundaries. An information system is not only the technology an organization uses, but also the way in which the organization’s people interact with the technology and the way in which the technology works with the organization’s business processes. Information systems are distinct from information technology in that an information system has an information technology component that interacts with the people and processes components.
Information technology departments in larger organizations tend to strongly influence information technology development, use, and application in the organizations, which may be a business or corporation. A series of methodologies and processes can be used in order to develop and use an information system. Many developers have turned and used a more engineering approach such as the System Development Life Cycle (SDLC) which is a systematic procedure of developing an information system through stages that occur in sequence. An Information system can be developed in house (within the organization) or outsourced. This can be accomplished by outsourcing certain components or the entire system.
A computer based information system, following a definition of Langefors, is:
a technologically implemented medium for recording, storing, and disseminating linguistic expressions,
as well as for drawing conclusions from such expressions.
which can be formulated as a generalized information systems design mathematical program.
