PRINCIPLES OF INFORMATION SYSTEMS DESCRIPTOR. General Course Description: Examination of information systems and their role in business.
As the name suggest, each FAIS support a particular function within the organization, e. In finance and accounting, managers use IT systems to forecast revenues and business activity, to determine the best sources and uses of funds, and to perform audits to ensure that the organization is fundamentally sound and that all financial reports and documents are accurate.
Other types of organizational information systems are FAIS, Transaction processing systems , enterprise resource planning , office automation system, management information system , decision support system , expert system , executive dashboard, supply chain management system , and electronic commerce system. Dashboards are a special form of IS that support all managers of the organization.
They provide rapid access to timely information and direct access to structured information in the form of reports. Expert systems attempt to duplicate the work of human experts by applying reasoning capabilities, knowledge, and expertise within a specific domain. Information technology departments in larger organizations tend to strongly influence the development, use, and application of information technology in the business. A series of methodologies and processes can be used to develop and use an information system.
Many developers use a systems engineering approach such as the system development life cycle SDLC , to systematically develop an information system in stages. The stages of the system development lifecycle are planning, system analysis and requirements, system design, development, integration and testing, implementation and operations and maintenance.
Recent research aims at enabling  and measuring  the ongoing, collective development of such systems within an organization by the entirety of human actors themselves.
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:. Geographic information systems , land information systems, and disaster information systems are examples of emerging information systems, but they can be broadly considered as spatial information systems.
System development is done in stages which include:. The field of study called information systems encompasses a variety of topics including systems analysis and design, computer networking, information security, database management and decision support systems. Information management deals with the practical and theoretical problems of collecting and analyzing information in a business function area including business productivity tools, applications programming and implementation, electronic commerce, digital media production, data mining, and decision support.
Communications and networking deals with the telecommunication technologies. Information systems bridges business and computer science using the theoretical foundations of information and computation to study various business models and related algorithmic processes  on building the IT systems   within a computer science discipline.
Several IS scholars have debated the nature and foundations of Information Systems which have its roots in other reference disciplines such as Computer Science , Engineering , Mathematics , Management Science , Cybernetics , and others.
Similar to computer science, other disciplines can be seen as both related and foundation disciplines of IS. The domain of study of IS involves the study of theories and practices related to the social and technological phenomena, which determine the development, use, and effects of information systems in organization and society.
In a broad scope, the term Information Systems is a scientific field of study that addresses the range of strategic, managerial, and operational activities involved in the gathering, processing, storing, distributing, and use of information and its associated technologies in society and organizations. This interaction can occur within or across organizational boundaries. Information systems are distinct from information technology IT in that an information system has an information technology component that interacts with the processes' components.
One problem with that approach is that it prevents the IS field from being interested in non-organizational use of ICT, such as in social networking, computer gaming, mobile personal usage, etc. A different way of differentiating the IS field from its neighbours is to ask, "Which aspects of reality are most meaningful in the IS field and other fields?
International Journal of Information Management , 30, There is a wide variety of career paths in the information systems discipline. Workers with management skills and an understanding of business practices and principles will have excellent opportunities, as companies are increasingly looking to technology to drive their revenue.
Information technology is important to the operation of contemporary businesses, it offers many employment opportunities.
The information systems field includes the people in organizations who design and build information systems, the people who use those systems, and the people responsible for managing those systems.
The demand for traditional IT staff such as programmers, business analysts, systems analysts, and designer is significant. Many well-paid jobs exist in areas of Information technology.
At the top of the list is the chief information officer CIO. Therefore, he or she actively participates in the organization's strategic planning process. Information systems research is generally interdisciplinary concerned with the study of the effects of information systems on the behaviour of individuals, groups, and organizations. Salvatore March and Gerald Smith  proposed a framework for researching different aspects of Information Technology including outputs of the research research outputs and activities to carry out this research research activities.
They identified research outputs as follows:. Although Information Systems as a discipline has been evolving for over 30 years now,  the core focus or identity of IS research is still subject to debate among scholars. Since the study of information systems is an applied field, industry practitioners expect information systems research to generate findings that are immediately applicable in practice.
This is not always the case however, as information systems researchers often explore behavioral issues in much more depth than practitioners would expect them to do. This may render information systems research results difficult to understand, and has led to criticism.
In the last ten years, the business trend is represented by the considerable increasing of Information Systems Function ISF role, especially with regard the enterprise strategies and operations supporting. It became a key-factor to increase productivity and to support new value creation. A number of annual information systems conferences are run in various parts of the world, the majority of which are peer reviewed.
