Development of information system is a set of activities, methods, best practices, ready to be delivered, and the automated equipment used by stakeholders to develop and maintain information systems and software.
Usually the system development is done if the old system had not kept pace / inadequate requirements or development of the company, so there are several opinions about the definition of system development, among others:
- Develop a new system to replace the old system as a whole or improve existing systems.
- A process for the application of information technology to a specific purpose or solve a problem.
- Sorting out a large and complex problem into several small pieces that can be managed.
Development of the system may mean constructing a new system to replace the old system as a whole / repair existing systems. With the development of the new system, it is expected that there will be improvements in the new system, namely improving:
- Performance: improvements to the performance of the new system to be more effective. Performance can be measured by throughput (the amount of work that can be done a certain time and a response time (the average time delay between transactions / employment coupled with a response time to respond to such work).
- Information: improvement of the quality of information presented.
- Economy: an increase of the benefits / advantages / deterioration of the costs incurred.
