The For site Company is screening three ideas for new service. Resource constraints allow only one idea to be commercialized at the present time. The following estimates have made for the five performance criteria that management believes to be most important:
Rating
Performance Criterion
Service A
Service B
Service C
Capital equipment investment required
0.6
0.8
0.3
Expected return on Investment (ROI)
0.7
0.3
0.9

0.7
0.5
Competitive advantage
1.0
0.4
0.6
Compatibility with EPA requirements
0.2
1.0
0.5
Calculate a total weighted score for each alternative. Use a preference matrix and assume equal weights for each performance criterion. Which alternative is best? Worst?
Suppose that the expected ROI is given twice the weight assigned to each of the remaining criteria. (Sum of weights should remain the same as in part (a).) Does this modification affect the ranking of the three potential services?
