Abstract
Several ROI (return on investment) methods have been addressed in the business world. They include Net Present Value (NPV) and Internal Rate of Return (IRR). How do we know which methods are good for managing risks? How do we know when ROI methods need to be changed due to, for example, organizational restructuring, merger, or acquisition? How do we compare? Once we know, what criteria should we use to select values for input to an ROI method for a particular organizational environment?
