5 Three new-product ideas have been suggested. These ideas have been rated as shown in Table 14.

TABLE 14 Product Criteria A B C Weight (%)
Development cost P F VG 10 Sales prospects VG E G 15 Producibility P F G 10 Competitive advantage E VG F 15 Technical risk P F VG 20 Patent protection F F VG 10 Compatibility with strategy VG F F 20 100 1 P = poor, F = fair, G = good, VG = very good, E = excellent.

a. Using an equal point spread for all five ratings (i.e.,P = 1, F = 2, G = 3, VG = 4, ), determine a weighted score for each product idea.What is the ranking of the three products?

b. Rank the criteria, compute the rank-sum weights, and determine the score for each alternative.
Do the same using the rank reciprocal weights.

c. What are some of the advantages and disadvantages of this method of product selection?
