system. If the candidate system meets all of the requirements at least as well as the baseline system, the score is 0. If it is less effective in any requirement, the score is less than 0. The upper portion (dark shading) of the bar shows capabilities that exceed those of the baseline system.

For example, scores for the Claymore (in Table 5-2), show that 7 of 9 requirements were met or exceeded (i.e., had a score of 0 or higher); the lower (white) portion of the bar has a value of 7 out of 9, or 78 percent of requirements met. In addition, 6 of the 9 requirements were exceeded (i.e., had a score of 1 or more); the upper (black) portion of the bar has a value of 6 out of 9, or 67 percent.

A second example illustrates some additional factors. The scores for the Hellfire (again in Table 5-2) range from −4 to +2, which indicates significant deficiencies in some areas and significant advantages in others. To account for the impact of these larger excursions, the scores are adjusted by the degree of deficiency or improvement. Because a score of +1 is the lowest score that would be considered an “improvement,” a score of +2 adds one additional point to the “improvements” score but does not affect the requirements score. Similarly, a score of −2 subtracts one point from the “requirements” score, and a score of −3 subtracts 2 points. In the case of Hellfire, 8 of 14 requirements are met (including the N/A as a “met” requirement), but deficiencies of 4 and 2 result in an adjusted requirements score of 4 out of 14, or 29 percent. Similarly, 4 of 14 requirements are exceeded, two by a score of +2, resulting in an adjusted improvements score of 6 out of 14, or 43 percent.

In general, if the total bar height in Figure 5-1 is high, the system is likely to be militarily effective. If the value of the lower portion of the bar is near 0, the system meets most of the military requirements. If the lower bar is much lower than 0, the system probably has significant differences from the baseline mine and will not perform some desired functions. However, that system may still be militarily effective if it performs some functions much better than the baseline system. Because the scoring criteria were not weighted, these graphs should be used only for assessing trends and making qualitative comparisons.
