Soft system Methodology - Essay Example Compare to hard problems soft problem are difficult to define. Feasibility study is an important phase in the software development process. It enables the developer to have an assessment of the product being developed. It refers to the feasibility study of the product in terms of outcomes of the product, operational use and technical support required for implementing it. Economic Feasibility: It refers to the benefits or outcomes. We are deriving from the product as compared to the total cost we are spending for developing the product. If the benefits are more or less the same as the older system, then it is not feasible to develop the product. In the present system, the development of the new product greatly enhance the accuracy of the system and cuts short the delay in the processing of Birth and Death application. The errors can be greatly reduced and at the same time providing great level of security. Hence, we do not need any additional equipment except memory of required capacity. Operational Feasibility: It refers to the feasibility of the product to be operational. Some products may work very well at design and implementation but may fall in the real time environment. It includes the study of additional human resources required and their technical expertise. Technical Feasibility: It refers to whether the software that is... Technical Feasibility: It refers to whether the software that is available in the market fully supports the present application. It studies the pros and cons of using particular software for the development and it's feasibility. It also studies the additional training need to be given to the people to make the application work. Implementation Plan The main plan for the system developed is to upgrading and existing system to proposed system. There are mainly 4 methods of upgrading the existing system to the proposed Parallel Run System Direct Cut-Over Method Pilot System Phase-in Method Parallel Run System: It is most secure method of converting from an existing to anew system. In this approach, both the systems are run in parallel for a specific period of time. During the period of if any serious problems were identified while using the new system, the new system is dropped and the older system is taken at the start point again. Direct Cut-Over Method: In this approach, the existing system is converted to the new system abruptly, some times over a weekend or even overnight. The old system is used until a planed conversion day. There exist no parallel activities. Pilot Method: In this approach, a working version of the system is implemented in one art of the organization such as a single work area or department. When the system is deemed complete it is installed through out the organization either all at once (direct cut-over) or gradually (phase-in). Phase-in Method: In this method, a part of the system is first implemented and over time, other remaining parts are implemented. SYSTEM ANALYSIS Analysis is the detailed study of the various operations performed by a system and their relationships within and outside of the system. A key question is:
