Your boss is a member of the library-site selection committee. She is not perfectly satisfied with the assessments shown in the table. Specifically, she wonders to what extent the assessed weights and individual utilities on the detail attributes could change without affecting the overall ranking of the four sites. Use an electronic spread sheet to answer this question, and write a memo that discusses your findings. (Hint: There is no specific way to attack a sensitivity analysis like this. One possibility is to es tablish reasonable ranges for the weights and then create a tornado diagram. Be sure that your weights add to 1 in each category!)
