Fiqure 2 shows that, if a second new equipment or technology feature is
introduced (which reduces the training time to reach proficiency), then the
time it takes for the groups to achieve the 50% criterion of proficiency

Figure 3 illustrates the relation between category and equipment
differences in terms of Isoperformance curves, where any point on the curve
identifies the same (Iso) performance. Note that the Equipment difference is
smaller than the “Personnel” difference.
