2. Systems Analysis and Design Fourth Edition The Systems Analyst’s Toolkit Part 2 Feasibility and Cost Analysis Tools
3. Systems Analysis and Design Fourth Edition Objectives Define economic feasibility
Identify the cost considerations that analysts consider throughout the SDLC
Understand chargeback methods and how they are used
Use cost-benefit analysis, payback analysis, return on investment analysis, and present value analysis
4. Systems Analysis and Design Fourth Edition Introduction A project is economically feasible if the future benefits outweigh the costs
The Systems Analyst’s Toolkit explains how to calculate a project’s costs and benefits
Cost-benefit analysis is performed when
Conducting a preliminary investigation
Evaluating a project
Making recommendations to management
5. Systems Analysis and Design Fourth Edition Describing Costs and Benefits Cost classifications
Costs can be classified in several ways
Tangible and intangible costs
Direct and indirect costs
Fixed and variable costs
Developmental and operational costs
6. Systems Analysis and Design Fourth Edition Describing Costs and Benefits Direct and indirect costs
Direct costs are those that can be associated with the development of a specific system
Examples: project team salaries, new hardware or software needed for the system
Indirect costs, or overhead expenses, cannot be attributed to a particular system
Examples: network administrator’s salary, copy machine rental costs
7. Systems Analysis and Design Fourth Edition Describing Costs and Benefits Fixed and variable costs
Fixed costs are relatively constant and do not depend on a level of activity or effort
Examples: salaries, rental charges
Variable costs depend on the level of activity
Examples: printer paper, supplies, telephone line charges
8. Systems Analysis and Design Fourth Edition Describing Costs and Benefits Developmental and operational costs
Development costs are incurred only once, at the time the system is developed
Examples: system development team salaries, user training, hardware purchase
Operational costs are incurred after the system is implemented and continue while the system is in use
Examples: system maintenance, ongoing training, annual license fees
9. Systems Analysis and Design Fourth Edition Describing Costs and Benefits Managing information systems costs and charges
Management requires cost information
Direct costs can be associated with a specific system, while indirect costs must be allocated
A chargeback method uses accounting entries to allocate the indirect IS costs
No charge method
Fixed charge method
Variable charge method based on resource use
Variable charge method based on volumes
10. Systems Analysis and Design Fourth Edition Describing Costs and Benefits Managing information systems costs and charges
Chargeback methods
No charge method
Treats IS department indirect expenses as a necessary cost of doing business, which benefits the entire company
The IS group is called a cost center because it generates no offsetting credits for services performed
User departments are not charged for indirect IS expenses
11. Systems Analysis and Design Fourth Edition Describing Costs and Benefits Managing information systems costs and charges
Chargeback methods
Fixed charge method
Indirect IS costs are divided among all other departments in the form of a fixed monthly charge, using various formulas
In this method, the IS group is called a profit center because it is expected to break even or show a profit on the sale of services
User departments are charged with a fixed share of indirect IS expenses
12. Systems Analysis and Design Fourth Edition Describing Costs and Benefits Managing information systems costs and charges
Chargeback methods
Variable charge method based on resource use
Resources might include CPU time, connect time to a remote computer, communication lines or printers required
Costs can vary from month to month
In this method, the IS group is called a profit center
User departments are charged with indirect IS expenses on the basis of resources used

14. Systems Analysis and Design Fourth Edition Describing Costs and Benefits Benefit classifications
Benefits can be classified into the same categories as costs
Tangible and intangible benefits
Direct and indirect benefits
Fixed and variable benefits
Developmental and operational benefits
Benefits also can be classified as positive benefits and cost-avoidance benefits
15. Systems Analysis and Design Fourth Edition Describing Costs and Benefits Positive and cost-avoidance benefits
Positive benefits are a direct result of the new information system
Examples: increased revenues, improved services, higher morale, better management
Cost-avoidance benefits refer to expenses that would be necessary if the new system is not installed
Examples: handling work with current staff instead of hiring, not having to replace hardware or software
16. Systems Analysis and Design Fourth Edition Cost-Benefit Analysis Cost-benefit analysis is the process of comparing anticipated costs to anticipated benefits
Cost-benefit analysis produces reliable information for making decisions
Common cost-benefit techniques
Payback analysis
Return on investment (ROI) analysis
Present value analysis
17. Systems Analysis and Design Fourth Edition Cost-Benefit Analysis Payback analysis Payback analysis is the process of determining how long it takes for an information system, to pay for itself Four step process 1. Determine the system’s initial development cost 2. Estimate annual benefits 3. Determine annual operating costs 4. Find the payback period by comparing total costs to accumulated benefits
