??? As a frequent flyer, I constantly and fervently hope that that proximity
goal is respected!
All of these facts reflect a fact that all engineers understand: complexity is difficult
to manage, and most interesting systems are complex. Worse, the compounding of
systems into systems of systems??”e.g., back to our airplane, the electrical, hydraulic,
propulsion, lift surface, life support, navigation, and other systems of aircrafts??”
tends to introduce new complexities in the form of unexpected overlaps of parts
and unexpected behavior of previously well-behaved systems.
The net result of the rising complexity of systems is the crying need for ways
to express component systems in ways that those designs can be easily shared
between design teams. A shared language is a crucial component of the design
methodology of any system or process, be it electrical, software, mechanical, or
chemical. And if that shared language is based on a pre-existing language, the team
which must share design will be up to speed more quickly and more able to complete
the design task??”and the more-demanding long-term maintenance and integration
task??”better, faster, and cheaper.
