In calculating Cost/Benefit Ratio, the total benefits are divided by the cost while for assessing ROI formula, â€Å"the costs are subtracted from the total benefits to produce the net benefits, which are then divided by the costs" (Phillips, 1997, p.43). Thus ROI is the Cost/Benefit Ratio calculation that is done by taking not the total benefits but the net benefits, which is calculated by subtracting total costs from the total benefits. The ROI formula takes into account the tangible costs and benefits alone while Cost/Benefit Ratio incorporates both tangible and intangible costs and benefits, thereby being more comprehensive (Phillips, 1997, p.73). The most often used validity testing approach is content validity just because it is more â€Å"cost-effective† (Phillips, 1997, p.90). This is also so because the â€Å"successful mastery of program content† as is shown by this validity test will be â€Å"related to improved job performance† (Phillips, 1997, p.280). Control groups, customer input and forecasting model are three methods that can be used to isolate the effects of an HRD training program (Phillips, 1997, p.105, 197, 70). In the control group method, it is the â€Å"results of the experimental group, when compared to the control group† that show the â€Å"impact of the HRD program† (Phillips, 1997, p.105). In a training program that is intended to ensure that customers come back to the company, customer input could be a valuable strategy to isolate the effects (Phillips, 1997, p.197). In a situation where â€Å"input and output variables are known†, it is easy to predict the effects out of logical reasoning and common sense and hence the forecasting model will be an effective method to isolate effects (Phillips, 1997, p.70). It is for consistency of data that an evaluator should gather
