Case Study: System Development
Sullivan University: HCA535
System development is a process in which programmers with organization contribution write codes to solve a problem that face the organization system or automate a procedure. There are three major systems development techniques that been used to solve systems’ problems. The system development techniques are SDLC (Systems Development Life Cycle), JAD (Joint Application Development), and RAD (Rapid Application Development). SDLC provides tools for controlling details within large development projects that solve structured problems. JAD enables the identification, definition, and implementation of information infrastructures. RAD supports the iteration and flexibility necessary for building robust business process support(Osborn, 1995). In this case study, the manager been asked to design, develop, and install a Patient Management Information System for a medical clinic in which three physicians practice general medicine. This system has to be operational in 6 months. There is one individual in the clinic staff who is reasonably well informed about information technology. Thus, the manager needs to determine which system development methodologies will use to solve this problem. To choose the appropriate development system, the manager need to use a process which consists of s (1) defining requirements, (2) designing an information system to fit those requirements, (3) building the code to deliver that system, and (4) testing to see whether the code works and the system does the job it was intended to do(Osborn, 1995). The requirement for this case study is to design and develop and install a Management Information System for a medical clinic that has three physicians within 6 months. Based on that, this process will take longer if we use the SDLC which is the traditional method that need narrative descriptions, data definitions, and sample screens. Moreover, producing a thorough, often...
