Trang 25Project Feasibility
Measure of how beneficial or practical the development of an information system will be to an organization.
Process by which feasibility is measured
Continuing process of feasibility assessment
Trang 26Scope of Feasibility Analysis
Trang 27Feasibility Dangers
A project that was once feasible may not
remain so - why not?
Feasibilities can often conflict!
What can you do if the project is not feasible
on all levels?
Trang 28Managing Expectations
Often most difficult aspect of a project
Tool for balancing priorities
Rows in matrix are project dimensions:
Cost
Trang 29Managing Expectations
Columns in matrix are the priorities:
Impossible to optimize all simultaneously!
Rule: 1 check per row & column
Trang 31Frequent Causes of Failures
Taking shortcuts with methodology
Cost of fixing errors, finding an error in:
Trang 32Frequent Causes of Failures
Scope & Feature Creep
Trang 33• Operational Feasibility
How well will the solution work in the organization?
• Technical Feasibility
How practical is the technical solution?
How available are technical resources and expertise?
Tests of Feasibility
Trang 35• Questions to Ask
Is the problem worth solving?
Will the solution to the problem work?
How do end users and management feel about the solution?
Has a usability analysis been conducted?
Operational Feasibility
Trang 36• Questions to Ask
Is the proposed solution practical?
Do we possess the necessary technology?
Do we possess the necessary technical
expertise?
Is the schedule reasonable?
Technical Feasibility
Trang 37• Cost-benefit analyses
How much will the system cost?
Development costs
Operation costs
Maintenance and support costs
Do we possess the necessary technology?
Do we possess the necessary technical
expertise?
Is the schedule reasonable?

Trang 39•Benefit analyses
Tangible benefits can be easily quantified.
Measured in terms of monthly or annual
savings, or of profit to organization
Intangible benefits more difficult to quantify.
Benefit Analysis
Trang 40Benefit Analysis
Tangible Benefits
• Fewer processing errors
• Increased throughput
• Decreased response time
• Elimination of job steps
• Increased sales
• Reduced credit losses
• Reduced expenses
Intangible Benefits
• Improved customer goodwill
• Improved employee morale
• Better service to community
• Better decision-making
Trang 41• Payback analysis
How long will it take to recoup the costs of this project?
Return on investment (ROI) analysis
Net present value analysis
Economic Feasibility
Trang 42• Compare candidate systems on basis of several characteristics
Better analysts always consider multiple solutions
