The Forsite Company is screening three ideas for new services. Resource constraints allow only one idea to be commercialized at the present time. The following estimates have been made for the five performance criteria that management believes to be most important: a. Calculate a total weighted score for each alternative. Use a preference matrix and assume equal weights for each performance criterion. Let the total of the weights equal 100. (Enter your responses as integers.) Which alternative is best? Worst? A. The best alternative is service C and the worst is service A. 'B. The best alternative is service B and the worst is service C. C. The best alternative is service B and the worst is service A. D. The best alternative is service A and the worst is service B. E. The best alternative is service A and the worst is service C. F. The best alternative is service C and the worst is service B. b. 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? The best alternative is now service with a total weighted score of (Enter your response rounded to one decimal place.)
