About Us

Traditionally, safety engineers have relied on text-/table-based solutions for the documentation of artifacts created during the development lifecycle. However, due to the increasing complexity of today’s safety-critical embedded systems, these solutions do not scale properly and new approaches for development and documentation are required. Fraunhofer IESE addresses this challenge by researching and developing integrated model-based safety engineering approaches, with a strong focus on architecture integration, traceability, reusability, and maintainability of safety-relevant artifacts.

What safeTbox can…
