Information systems are databases used for the collection, storage, and analysis of information within an entity. Systems surround us and MIS teaches us how to use information technology in order to streamline business processes and create solutions. The manner in which we are able to manipulate information creates value, and systems create automated processes that help us process and analyze that information.
Systems can be developed internally or externally. The latter can be done via outsourcing or cloud computing, which has become increasingly popular and provides high scalability, though also comes with a partial loss of control and heightened security risks.
Internal development can be done via Life Cycle Development, however this method is time consuming as it contains 6 stages, lots of documentation, and has become the less popular option. Instead, companies are turning to Rapid Application Development to deploy their systems. RAD format is as follows: a prototype of a system is launched, and then modified based on user feedback. RAD is an example of an agile SDLC.
