The Modified Internal Rate of Return is an underused measure for selection of projects that a company can choose because it is more effective at dealing effectively with periodic free cash flows that develop from the time that an asset is purchased through its life to the point where it is sold, ranking projects and variable rates of return through the project life. The Internal Rate of Return is an inefficient model to make decisions with because it lack the ability to account for the periodic free cash flows, proper ranking and variable returns from certain projects.

Choosing the hardware and software to improve efficiencies that has an initial cash out flow for the hardware and yearly subscription fees for the software, cash inflows from the deployment and re-allocation of human assets to revenue generating positions, reductions in costs, improving patient flow to allow for more patient visits per day involve multiple cash flows and would be difficult to analyze with the Internal Rate of Return. This is often complicated with the scale of the deployment. The hospital system may decide that it wants to deploy 150 units. The scale of this program can be in the millions of dollars and costs savings and the reallocation of employees to revenue producing positions can far exceed the cost of the technology over a significant period of time. This case it can be seen that the using the Internal Rate of Return with the potential for multiple additional cash flows can be difficult. If there were no salvage or trade in value to the purpose built hardware systems and those systems had to be disposed of in an environmentally friendly way with a negative cash flow. This produces the problem of multiple rates of rates of return. This is similar to many examples of strip mines where there is a cash outflow at start up, cash inflows during the project and then cash outflow to return the land to pristine condition. The internal rate of return on these cases tends to produce astonishingly high or astonishingly negative
