However, when you look at the underlying
system models it could be just the opposite. It all depends on the detailing
depth of the model. For example, we could model a car to include even the tiniest
little screw. In the system model for an aviation system, however, we have airplanes
and airports as our smallest units.
You have just learned what the fi rst part of the term systems engineering
means. The second part, engineering , generally stands for a discipline that uses
methods and tools in a structured way to develop a product.
Putting the two words together, the term systems engineering describes methods
used to successfully develop systems.
Systems engineering concentrates on the defi nition and documentation of
system requirements in the early development phase, the preparation of a system
design, and the verifi cation of the system as to compliance with the requirements,
taking the overall problem into account: operation, time, test, creation, cost and
planning, training and support, and disposal [45].
Systems engineering integrates all disciplines and describes a structured development
process, from the concept to the production to the operation phase and
fi nally to putting the system out of operation.
