The Forsite Company is screening three ideas for new services. Resources constraints allow only one idea to be commercialized at the present time. The following estimated 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. Which alternative is best? Worst?
b. Suppose that the expected ROI is given twice the weight assigned to each of the remaining criteria. (Sum of weight should remain the same as in part (a). Does this modification affect the ranking of the three potentialservices?
