In simple words, CBA is an analysis to determine the cost to start, run, and maintain a project (or any other initiative) and the benefits received over a certain period. By performing CBA, we compare all the anticipated benefits with all the associated costs of the project.
Why Conduct Cost Benefit Analysis?
To make informed decisions before starting a project or selecting one among multiple options.
To set the right goals for a project.
To define success criteria by identifying quantifiable results—what to measure and how to measure.
To estimate project costs and identify required resources.
Important Considerations
Often, assumptions are made about project benefits without defining how they will be realized and measured. Quantifying returns/benefits is the only way to ensure they are achieved later. A famous saying states, "If you cannot measure something, you cannot make it." Many projects start due to market trends, where everyone repeats a few benefits, leading to projects being undertaken without clear objectives.
Key Considerations for IT Projects
Costs
Development Costs
For software development projects, consider:
Feasibility or due diligence costs
Estimated costs for Requirement Analysis (RA), Design, Coding, Testing, and Deployment (developer costs or salaries)
Training costs
Tools, IDEs, and other development necessities
Equipment costs
Operational Costs
Installation costs
Maintenance costs
Personnel costs
Equipment costs
Site upgrades
End-user training costs
Non-Recurring Costs
Capital costs
Data Processing Equipment (Desktops, Laptops, Servers, Networking Equipment)
Software (Applications, Operating Systems, Databases)
Other one-time costs (Infrastructure, Salaries & Compensation, Contracting, Studies, Data Preparation, Travel, Training, Overheads, Parallel System Run Costs)
Recurring Costs
Rent and infrastructure expenditures
Salaries and compensations (recurring type)
Contracting costs
Data Collection
Software upgrades
System maintenance and support
Travel
Training
Supplies
Other recurring expenses
Intangible Costs
Productivity loss
Management overhead
Benefits
Direct Benefits (Tangible)
Direct benefits impact a business’s bottom line and are easily measurable:
Reduced effort/manpower
Reduced non-labor costs
Better and/or more services to internal or external customers (new business opportunities)
Operational efficiency improvements
Cost savings from business process improvements
Service cost reduction
Indirect Benefits (Intangible)
Indirect benefits are harder to measure but positively impact an organization. These include:
Improved decision-making
Better risk management
Enhanced employee satisfaction
Strengthened customer relationships
Measuring and quantifying indirect benefits is essential. If a project’s CBA shows a higher contribution of indirect benefits than direct ones, it may indicate future risks and ambiguity. If direct benefits are hard to show at the beginning, achieving and quantifying them later can be even more difficult, leading to a high-claim, no-gain scenario.
Analysis Approach
Total Cost Calculation
Summing recurring and non-recurring costs for each year of the system’s life to estimate the total cost.
Total Benefits Calculation
Adding up all identified benefits to determine total anticipated benefits.
Cumulative Benefits Calculation
Adding all benefits received each year (cash inflows) and calculating cumulative benefits at the end of each year.
Net Benefits / Net Cash Flow Calculation
Subtracting total costs from total benefits for each year to determine net benefits.
Net Present Value (NPV) Calculation
NPV (for a period of N) = - Initial investment
Where:
R = Net cash flow at the end of each period
i = Required rate of return per period (organization-defined discount rate)
N = Number of periods generating cash inflows
A common method to choose the discount rate (i) is to determine the return the funds could generate if invested in a different financial instrument.
Internal Rate of Return (IRR) Calculation
IRR helps compare the profitability of two projects. It is the discount rate at which NPV equals zero.
If comparing two projects, the one with the higher IRR is generally the better investment.
By following this structured approach, organizations can make informed decisions, ensure project feasibility, and maximize returns on investment.
