What is the engineering of information systems?
Information systems engineering includes all aspects of building and maintenance of complex systems that solve real problems. System engineering begins with an analysis of the problem to be solved by the information system, undergoes system design and development, and ends with the integration of the final solution. This discipline is open to those who have information about information technology and those who have technical business background. System engineering tends to go through all engineering areas so that its experts can create a flexible problem solution. Every engineer must analyze the problem thoroughly to work to create a solution. This analysis of the information systems engineering is essential for creating a final product. The engineer must perform control and discipline to assess the problem. A defective analysis can lead to an inaccurate or incomplete solutue to a problem. Information created in the analysis phase will lead the information system engineering process to the system design that includessteps needed to solve a business problem. Generally, the design of the system is complicated when the original problem was complex; However, if the engineers have interrupted this problem during the problem analysis, the design of the system may be less complicated.
After the system has gone through several design discussions, the information systems engineering process will then move to the development of the system itself. Depending on the type of information system created, engineers can write code, buy software applications, or use existing systems to build a solution. Some information systems are a combination of a code written by The Group designing solutions and programs of third parties. The specified time frame in which the solution must be ready for use can also determine the amount of custom code created for the system.
Integration of solutions throughout the organization is the final phase of implementation of the system in the engineering process of informationh systems. This phase involves using the system knowledge to customize business processes or other application domains to work with the system itself. Each of the different areas of business must understand its location in the information system so that the system can function properly and efficiently. Integration helps every business unit to manage its part of the system.
