System development is a procedure in which coders with organisation part write codifications to work out a job that face the organisation system or automatize a process. There are three major systems development techniques that been used to work out systems’ jobs. The system development techniques are SDLC ( Systems Development Life Cycle ) . JAD ( Joint Application Development ) . and RAD ( Rapid Application Development ) . SDLC provides tools for commanding inside informations within big development undertakings that solve structured jobs. JAD enables the designation. definition. and execution of information substructures. RAD supports the loop and flexibleness necessary for constructing robust concern procedure support ( Osborn. 1995 ) . In this instance survey. the director been asked to plan. develop. and put in a Patient Management Information System for a medical clinic in which three doctors pattern general medical specialty.
This system has to be operational in 6 months. There is one person in the clinic staff who is moderately good informed about information engineering. Therefore. the director needs to find which system development methodological analysiss will utilize to work out this job. To take the appropriate development system. the director demand to utilize a procedure which consists of s ( 1 ) shaping demands. ( 2 ) planing an information system to suit those demands. ( 3 ) constructing the codification to present that system. and ( 4 ) testing to see whether the codification works and the system does the occupation it was intended to make ( Osborn. 1995 ) . The demand for this instance survey is to plan and develop and put in a Management Information System for a medical clinic that has three doctors within 6 months.

Based on that. this procedure will take longer if we use the SDLC which is the traditional method that need narrative descriptions. informations definitions. and sample screens. Furthermore. bring forthing a thorough. frequently multi-volume description of system demands can go such a time-consuming undertaking that it begins to widen the expected life of a development undertaking. On the other manus. JAD tends to trust on informations theoretical accounts to supply demands definition and paradigms to capture concluding design inside informations. The informations mold can bring forth thorough system specifications more rapidly than SDLC narrations. particularly through the usage of computer-aided package technology ( CASE ) tools.
The RAD relies on a series of iterative paradigms to stipulate and papers demands. The technique reverses the scheduling accent usually found in SDLC undertakings by puting a rolled series of release day of the months and dynamically seting system characteristics to suit. Repeating paradigms gives demands the chance to germinate and the flexibleness to alter if needed ( Osborn. 1995 ) . Since the undertaking is for little clinic. which mean that the budget is limited. SDLC to the usage of expensive mainframes to understand minutess. JAD to the demand for pull offing informations distribution following the coming of minicomputers. and RAD to the development of concern procedure support based on networked client/server workstations. SDLC provides tools for commanding inside informations within big development undertakings that solve structured jobs.
JAD enables the designation. definition. and execution of information substructures. RAD supports the loop and flexibleness necessary to constructing robust concern procedure support. Thus. based on the information that discussed earlier. I recommend utilizing the RAD method because the clinic is little one which needs cheap system and the system will necessitate support particularly that there is merely one individual who informed about utilizing information engineering. In add-on. the clip limits that clinic has will suit besides the RAD method. Literature showed that RAD proves most utile for systems support of unstructured concern procedures. This non means that this system will restrict the concern because when the concern grows up the system can travel for more construction system ( Osborn. 1995 ) .
