This report outlines a method for performing Return-On-Investment ROI studies for the Geographic Resources Analysis Support System GRASS. An ROI analysis helps to calculate the benefit-to-cost ratio BC as a basis for decisionmaking in acquiring GRASS hardware and software, in evaluating the economies of using GRASS software in new applications, or in verifying actual against projected costs of running GRASS. This ROI methodology is composed of three data sheets with instructions and a final worksheet on which the ROI may be calculated. The first two data sheets help to calculate the cost of data acquisition and input hardware, software, and labor costs, and data manipulation and output hardware upgrades, peripherals, labor, and materials. The third data sheet helps to calculate a benefits analysis of the system, and the final calculation worksheet helps to compute a summation of all accrued costs and benefits.
