Lessons Learned Building a Tool for Workflow + .

As automotive manufacturers continue to release more advanced autonomous features, the effort required to ensure safety is increasing. This is a result of the growing complexity of automotive systems, and the increased level of safety assurance required for higher levels of autonomy. The Workflow+ model-based framework was developed in response to these challenges, to provide a way for safety assurance to be developed rigorously and with automated tool support. In this paper we discuss our experiences and lessons learned while developing Eclipse-based tooling for Workflow+ during a collaborative research project with a large automotive OEM.
