Case Study: System Development Essay

administration instruction is a movement in which programmers with organization contribution write scratchs to earn a problem that face the organization schema or alter a procedure. There are three major outlines festering techniques that been utilize to solve brasss problems. The schema development techniques are SDLC ( forms Development Life Cycle), JAD (Joint diligence Development), and rad (Rapid Application Development). SDLC provides tools for controlling details at bottom large development projects that solve structured problems. JAD enables the identification, definition, and implementation of education infrastructures. radian agrees the iteration and flexibility necessary for building robust business process support(Osborn, 1995). In this eluding regard, the manager been asked to design, develop, and install a Patient Management education System for a medical clinic in which three physicians practice general medicine.This body has to be operational in 6 months. There is nonpareil unmarried in the clinic staff who is reasonably well informed about information technology. Thus, the manager needs to determine which frame development orderologies will uptake to solve this problem. To choose the appropriate development system, the manager need to give 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 multi-volume description of system requ irements hind end become such a clock-consuming depute that it begins to extend the expected life of a development project. On the opposite hand, JAD tends to rely on data models to provide requirements definition and prototypes to capture final exam design details. The data modeling can produce thorough system specifications more quickly than SDLC narratives, especially through the use of computer-aided software engineering (CASE) tools.The RAD relies on a series of iterative prototypes to specify and register requirements. The technique reverses the scheduling emphasis normally found in SDLC projects by setting a rolling series of release dates and dynamically adjusting system features to fit. Iterating prototypes gives requirements the opportunity to evolve and the flexibility to change if needed(Osborn, 1995). Since the project is for small clinic, which soaked that the budget is limited. SDLC to the use of expensive mainframes to understand transactions, JAD to the need f or managing data scattering following the advent of minicomputers, and RAD to the development of business process support based on networked client/server workstations. 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 to building robust business process support. Thus, based on the information that discussed earlier, I recommend using the RAD method because the clinic is small one which needs inexpensive system and the system will need support especially that there is only one person who informed about using information technology. In addition, the time limits that clinic has will fit also the RAD method. Literature showed that RAD proves close useful for systems support of unstructured business processes. This not means that this system will limit the business because when the business grows up the system can move for more structure system(Osborn, 1995).ReferencesGlandon, G., Smaltz, D. & Slovensky, D.
