# SDV Systems Engineering

**SDV Systems Engineering** combines **LeanSE** and **SDVxMBSE** to enable **agile, model-driven development** while maintaining **safety, compliance, and cross-domain coordination**.

* **LeanSE** integrates **systems engineering into agile workflows**, managing dependencies efficiently without slowing innovation.
* **SDVxMBSE** ensures the **co-existence of model- and code-centric development**, with **VHAL as the bridge**, enabling early validation, simulation, and continuous integration.

This approach streamlines **feature development, verification, and integration**, aligning **systems thinking with the fast-paced SDV lifecycle**.
