Walker Accounting Software is marketed to small accounting firms throughout the U.S. and Canada. Owner George Walker has decided to outsource the company\'s help desk and is considering three providers: Manila Call Center (Philippines), Delhi Services (India), and Moscow Bell (Russia). The following table summarizes the data Walker has assembled. Which outsourcing firm has the best rating? (Higher weights imply higher importance and higher ratings imply more desirable providers.) In the following table, compute the weighted average score for each of the three providers (enter your responses rounded to one decimal place).

Solution

Total weighted score can be calculated by multiplying each rating by the weight and adding the products in each column.

For Manila (A) :-

Total weighted score = (.5*8) + (.1*5) + (.2*4) + (.2*5) = 6.3

For Delhi (B) :-

Total weighted score = (.5*8) + (.1*4) + (.2*6) + (.2*7) = 7

For Moscow (C) :-

Total weighted score = (.5*10) + (.1*4) + (.2*9) + (.2*4) = 8

From the above table, Moscow (C) has the highest/ best rating (8).

Criterion	Weight (W)	Manila (A)	Delhi(B)	Moscow (C)
Flexibility	0.5	8	8	10
Trustworthiness	0.1	5	4	4
Price	0.2	4	6	9
Delivery	0.2	5	7	4
Total Weighted Score	1	6.3	7	8
