To illustrate some important issues in conducting trade studies, consider the following simplified example. The trade study involved six alternative system concepts. Five Measures of Effectiveness (MOEs) were used, each weighted equally. For simplicity's sake, the MOEs have been titled A, B, C, D,and E. After values were assigned to each MOE of the six alternatives, the results were the following:

Weighted MOE	A	B	C	D	E	Total
Concept I	1	1	5	4	2	13
Concept II	3	3	2	5	4	17
Concept III	4	1	5	5	5	20
Concept IV	2	2	3	5	1	13
Concept V	4	4	4	4	4	20
Concept VI	1	1	1	3	3	9

Note that two stood out well above the rest, both receiving the same total number of points.

On the basis of the above rating profiles:

1. Would you conclude Concept III to be superior, equal, or inferior to Concept V? Explain your answer.
2. If you were not entirely satisfied with this result, what further information would you try to obtain?
3. Discuss potential opportunities for further study that might lead to a clearer recommendation between concepts III and V.
