In feasibility study the work of an analyst is to identify a new system, describe it and evaluate it and after it select the most appropriate system for the expected work.
The principal purpose of feasibility study is to find out any sort of opportunity to solve the problem.
Feasibility study, in fact, is neither system analysis nor system design, on the contrary feasibility study is a cross life cycle activity and it is continuously accomplished in the whole system project.
The most important and difficult part of a feasibility study is to identify the new system and to evaluate its performance and cost.
From the time of initial investigation, the analyst keeps working with the representa-tives of the user-organisation.
The second benefit of the system team is, we while making the plan, associate the user and the management with the system making them equally important partners.
The second step of feasibility study is to appraise data flow diagram which were prepared during system performance definition activities.
The third step of feasibility study is to develop the candidate physical system which can present the output selected in data flow program.
Generally, there are a lot of members in the team who should be extensively evaluated.
The fourth step of feasibility study is to do the initial evaluation of the system candi-dates. Its objective is to reduce the number of system candidates so that they can be arranged well.
The fifth step in feasibility study is to prepare a detailed description of the system.
The system cost includes the cost on developing and running the system after its implementation. The cost factors, which are important in system evaluation, consist of equipments, facilities and the training expenditures.
The accuracy of the candidate doesn't denote the accuracy of the device but it stands for the accuracy of the system.
The criteria of operational and technical feasibility measure the capability of problem and solution.
The operational feasibility is man based while the technical feasibility is computer based.
The economic feasibility is related to the cost and benefit of the information system.
The schedule feasibility is related to the project program.
The criteria of operational feasibility measures the importance of the problem.
It is seen in technical feasibility whether it is practical and appropriate.
Good system analysts give equal importance to both right work and right duration.
There should be no disadvantage in the work done in a deadline besides, going beyond the deadline for maintaining the quality of the work is not supposed to be the characteristic of a successful system analyst.
