167 A P P E N D I X G Supplemental Guidance on Use of Simulation Results in ROI Analysis As described in the ROI calculation guidance in Chapter 3 and in several of the references included in the review described in Appendix A, often simulation tools can be used to help predict the effects of implementing a new TAM system or improved process. The calculation tool documented in Chapter 4 specifically accommodates simulation results from three possible systems: HERS-ST, NBIAS, and an agency PMS.
