1. THE FEASIBILTY STUDY
LECTURE-5

2. FEASIBILITY STUDY
The examination of the existing system was completed in Preliminary Survey.
In Feasibility Study various possibilities are evaluated in which the existing system can be changed.
Here the Objectives and Scope of the system are specified.
Objectives of the System
Scope of the System

Outcomes of Systems Analysis

3. OBJECTIVES OF THE SYSTEM
A successful IS must achieve all its stated objectives. During the preliminary survey, if it is found that objectives are not clearly defined, then these are specified here. While considering each alternative, it is examined whether a specific alternative can be supportive in achievement of objectives or not.

4. SCOPE OF THE SYSTEM
Scope defines the limits or boundaries of the system.
Scope definition is necessary so that study team can restrict their analysis to only problem-related factors.
Without defining the scope, the energy and resources may get wasted.

5. DETERMINING FEASIBILITY
During Preliminary Survey, various options are identified as the solutions to the problem.
The feasibility of these alternative solutions need to be thoroughly evaluated.
These alternative solutions are analyzed with respect to following four factors.
TECHNICAL FEASIBILTY
OPERATING FEASIBILITY
TIME FEASIBILTY
ECONOMIC FEASIBILTY

6. TECHNICAL FEASIBILTY It is related to technical aspect of the solution
TECHNICAL FEASIBILTY It is related to technical aspect of the solution. If the software and hardware required for the solution is easily available, then it is a technically feasible solution.

7. OPERATING FEASIBILTY Operating feasibility of a solution shows that it achieves its operational objectives. Operating feasibility can best be determined by user satisfaction. Another important factor is operational performance.

8. TIME FEASIBILTY
Basic yard stick for determining this feasibility is the time allowed by the company.
A time feasible solution can be implemented within the specified time.
Time is affected by four factors:-
Equipment delivery time
Software delivery time
Training Time
Conversion Time

9. ECONOMIC FEASIBILTY Whether this solution offers financial benefits to the organization? Preliminary calculations are done to determine that the benefits obtained worth the costs.

10. DETERMINING ECONOMIC FEASIBILITY
Economic feasibility is the most important factor for determining the feasibility of an alternative solution.
Hence it requires a special and in-depth analysis.
The study team compares the projected Costs with projected Benefits.
Annual Costs and Onetime costs
Annual Benefits

11. DETERMINING COSTS Expected costs can be projected with some accuracy
DETERMINING COSTS Expected costs can be projected with some accuracy. Previous projects estimates can be helpful. Old estimates can be modified on the basis of:- scope, technology, experience, inflation If no relevant previous project is available, then hire a consultant.

12. DETERMINING BENEFITS
Benefits are easily identified in qualitative terms but require to be specified more quantitively for the satisfaction of study team.
For this purpose it is tried to relate benefits with three-levels of decision-making activity.
Strategic Planning
Management Control
Operational Control

13. COMPARING COSTS & BENEFITS
Three methods can be used to compare Costs & benefits.
Net Cost or Benefit:
- Also called cost-benefit analysis.
- appropriate for comparing Annual/onetime cost with Annual/onetime benefit
- ignores time value of money
Return on Investment
- a popular measure -
Discounted Cash Flow Methods
- These methods consider the time value of money.
- Includes techniques such as Internal rate of return , net present value , present value index
Annual Benefits
Annual Costs
Onetime Development costs
ROI = -

14. REPORT TO MANAGEMENT
At the conclusion of the Feasibility Study, the system study team prepares a report describing its findings.
May be smaller or larger in volume.
Copies provided to top management, long-range systems planning group and user departments
Report form may vary:
. Detailed report
. Executive Summary and Details

15. ILLUSTRATION: Contents of a System study Report
