Feasibility is measure of how beneficial the development of an information system would be to an organization. Feasibility analysis is the process by which we measure feasibility. It is an ongoing evaluation of feasibility at various checkpoints in the life cycle. At any of these checkpoints the project may be canceled, revised or continued. There are four feasibility tests: operational, technical, schedule and economic.
Operational feasibility: it is a measure of problem urgency or solution acceptability. It includes measure of how the end- users and managers feel about the problems or solutions.
Technical feasibility: it is a measure of how practical solutions are and whether the technology is already available within organization. If technology is not available to the firm, technical feasibility also looks at whether it can be acquired.
Scheduler feasibility: it is a measure of how reasonable the project schedule or deadline is. Economic feasibility: it is a measure of whether the solution will pay for itself or how profitable a solution will be for management, economic feasibility is the most important for four measures.
