Based on integral subsystem considerations, any associated supporting element
adds explicit performance limits to the structural design, based on system
engineering concepts. On the other hand, initiation of critical subsystem
development requires considerable systems analysis and trade-off studies to
arrive at the total system rationale. In particular, the independent
functional principle is further compounded when taking into account the
sophisticated hardware. In this regard, a constant flow of effective
communication recognizes other systems' importance and the necessity for the
preliminary qualification limit. Interestingly enough, a large proportion of
interface coordination communication must utilize and be functionally
interwoven with the management-by-contention principle.
