FEASIBILITY STUDY

Feasibility study is to check the viability of the project under consideration. Theoretically various types of feasibilities are conducted, but we have conducted three type of feasibilities explained as under.

ECONOMIC FEASIBILITY

With the manual system the operating cost of the system is about 5 Lacks P.A.. This cost comprises salary of 25 people, stationary, building rent, electricity, water, telephone etc. But with the new system this reoccurring cost comes out to be about 1 Lacks P.A. Hence the new system is economically feasible.

TECHNICAL FEASIBILITY

The new system requires only 3 trained person to work with the system and in overall 5 people per office are sufficient. So we will identify 6 best people from existing system and train them.

As our existing system is purely manual, so we need a one time investment of Rs 50k for the purchase of 3 computers, a laser printer, AC and networking etc. It requires 1 Lacks PA as a operating cost.

With the above details our system is technically feasible as after investing 1 Lacks in a year, the College is still saving Rs 4Lacks PA.

OPERATIONAL FEASIBILITY

The new solution is feasible in all sence but operationally it is not. The new system demands the expulsion of at least 15 people from the staff. It creates an environment of joblessness and fear among the employees. It can lead to an indefinite strike in the college also. So the management must take corrective actions prior in advance in order to start the further proceedings.
