ABSTRACT
The performance of new systems capabilities for govern-
ment agencies and industry are often examined using simu-
lators. The simulators provide insight into how the new
capabilities will perform. Typically, these simulators shed
little light on reliability, complexity, and other software
engineering aspects of the proposed changes. The correla-
tion between the complexities of the proposed capabilities
with that of an earlier system version can be used to bound
the new system’s trustworthiness, performance, schedules,
and costs.
