From the system engineer ??™ s
perspective the model also serves for managing the entire lifecycle of the system,
in addition to being used to specify the system design.
Modeling with SysML offers a good traceability of aspects, e.g., the realization
of a requirement in the design (see satisfy in Section 4.3.4).
Integrate
A system will not exist in solitude and serve an end in its own. It is embedded in
an environment, and it will interact with this environment. This step integrates the
system. It includes, e.g., the definition of system interfaces.
Launch the system
A system is created on the basis of a specified design model and taken into operation.
The models from the previous steps specify implementation requirements
for software, hardware, mechanics, etc.
Assess performance
Once the system is ready for operation it is tested and measured. The values resulting
from tests and measurements have to comply with the requirements. In SysML
the connection between test model and requirement model is made by use of the
verify relationship (Section 4.
