  1. Toolkit Part 3

  2. Toolkit Objectives • Define economic feasibility • Classify costs and benefits into various categories, including tangible or intangible, direct or indirect, fixed or variable, and developmental or operational • Understand chargeback methods and how they are used

  3. Toolkit Objectives • Use payback analysis to calculate the length of time that it takes for a project to pay for itself • Use return on investment analysis to measure a project’s profitability • Use present value analysis to determine the value of a future project measured in current dollars

  4. Introduction • You need to know how to calculate costs and benefits when you conduct preliminary investigations, evaluate IT projects, and make recommendations to management • Financial analysis tools are important throughout the systems development life cycle

  5. Describing Costs and Benefits • You must review a project’s costs and benefits at the end of each SDLC phase so management can decide whether or not to continue the project • Economic feasibility • Total cost of ownership (TCO)

  6. Describing Costs and Benefits • Cost Classifications • Tangible costs • Intangible costs • Direct costs • Indirect costs or overhead expenses • Fixed costs • Variable costs • Developmental costs • Operational costs

  7. Describing Costs and Benefits • Managing Information Systems Costs and Changes • Chargeback method • No charge method • Cost center • Fixed charge method • Profit center

  8. Describing Costs and Benefits • Managing Information Systems Costs and Changes • Variable charge method based on resource usage • Resource allocation • Connect time • Server processing time • Variable charge method based on volume

  9. Describing Costs and Benefits • Benefit Classifications • You must classify the benefits that the company expects from a project • Like costs, benefits can be classified as tangible or intangible, fixed or variable, and direct or indirect • Positive benefits • Cost-avoidance benefits

  10. Cost-Benefit Analysis • Cost-benefit analysis • Many cost-benefit analysis techniques exist • Three most common methods: payback analysis, return on investment analysis, and present value analysis • The objective is the same: to provide reliable information for making decisions

  11. Cost-Benefit Analysis • Payback Analysis • Payback period • Carry out the following steps • Determine the initial development cost of the system • Estimate annual benefits • Determine annual operating costs • Find the payback period

  12. Cost-Benefit Analysis • Payback Analysis • Economically useful life • Calculate the time it takes for the accumulated benefits of an information system to equal accumulated costs of developing and operating the system

  13. Cost-Benefit Analysis • Payback Analysis • Some managers are critical of it because it places all the emphasis on early costs and benefits and ignores the benefits received after the payback period • Even with its drawbacks, payback analysis is a widely used tool

  14. Cost-Benefit Analysis • Using a Spreadsheet to Compute Payback Analysis • First step is to design the worksheet and label the rows and columns • After entering the cost and benefit data for each year, you enter the formulas • You will need a formula to display cumulative totals, year by year

  15. Cost-Benefit Analysis • Return on Investment Analysis

  16. Cost-Benefit Analysis • Using a Spreadsheet to Compute ROI

  17. Cost-Benefit Analysis • Present Value Analysis • Time value of money • Present value analysis • Present value • Present value tables • Net present value (NPV)

  18. Cost-Benefit Analysis • Present Value Analysis • In theory, any project with a positive NPV is economically feasible • Can also be used to compare and rank projects • Provides solutions to the shortcomings of payback analysis and return on investment analysis

  19. Cost-Benefit Analysis • Using a Spreadsheet to Calculate Present Value • There is one more way to use a worksheet in present value analysis • Most spreadsheet programs include a built-in present value function that calculates present value and other time-adjusted variable factors

  20. Toolkit Summary • Must be concerned with economic feasibility throughout the SDLC • Must classify project costs as tangible or intangible, direct or indirect, fixed or variable, and developmental or operational • Every company must decide how to charge or allocate information systems costs and the chargeback method

  21. Toolkit Summary • You also must classify system benefits • Present value analysis adjusts the value of future costs and benefits to account for the time value of money • Many companies use present value analysis to evaluate and rank projects • Toolkit Part 3 complete
