<br />30 <br /> <br />A, Case Study Continued <br />In Section II, four basic alternatives were being compared using <br />economic criteria only, The matrix that will be developed demonstrates <br />the display of the degree to which each alternative meets each objec- <br />tive established, <br />In this case we will focus only on Decision Unit (Reach) 103-105, <br />Assume that of the objectives in Table 1-1 the decision makers choose <br />to really consider only four, Of all the alternatives available, <br />assume the screening process has reduced them to three; nonstructural <br />program, hard channel and soft channel, <br />Table 111-1 presents a display of the positive (+) and negative <br />(-) impacts of these three alternatives on the four Objectives con- <br />sidered, There is considerable room for innovation and the example <br />shown is neither very compl~te nor the only way to present the infor- <br />mation, <br />The information shown 0n Table 111-1 must be repeated for all <br />DeCision Units, Note that net benefits, benefit-cost ratios and <br />investment required are als0 presented, Although decisions are usually <br />made based on total information, it is useful to have the individual <br />numbers for Decision Units displayed, <br />It will also be necessary to prepare summary tables with the <br />information on Table 111-1 for all Decision Units aggregated together, <br />
