Today, Systems engineering is validated in the lab, not on the computer.

Challenges for Systems Engineering Processes

Disparate tools are difficult to integrate into a systemsmodel for verification.

Standalone tool for requirement mgmt Standalone tool for architecture design

Multitude of 3D and 0D tools andunsynchronized models

Limited traceability from requirements to detailed

product designs and models.

Limited integration between the embedded softwaredevelopment process and physical product modeling.
