As [announced previously](http://discourse.ros.org/t/safety-critical-wg-2022-roadmap-safety-education/24382), the ROS 2 Safety Critical WG plans to work on two topics in 2022.

One of the topics we have identified for 2022 is the advancement and possibly extension of the [quality declaration template](https://www.ros.org/reps/rep-2004.html#quality-declaration-template) for safety-critical development.

One could for example imagine to extend the current levels, add new levels or provide a specific version for safety-critical packages. We might also look at supporting tools e.g. [OpenGADES](https://wiki.eclipse.org/images/2/24/OpenGADES_DocumentationAndEngineeringSystem.pdf) for requirements management. Alongside the quality declaration work, it could be useful to try it out and implement the proposals for an example package. For [Eclipse iceoryx](https://iceoryx.io) a [tailored version](https://github.com/eclipse-iceoryx/iceoryx/blob/master/CONTRIBUTING.md#quality-levels) of the quality declaration was created. It goes beyond level 1 and could provide input for the WG.

We’ll be using the safety WG [GitHub repository](https://github.com/ros-safety/safety_working_group) to develop and document the work.

Who would be interest to participte working on this topic?

Looking forward to your feedback!

Thanks,  
Simon

This is a good 1st step in the safety plan for 2022.  
I think mapping SIL, ASIL, PL levels in the document to each quality level would be good. It would give each developer the information on what is needed from a development standpoint in making safety critical code.  
I don’t think we can map out each standard’s requirements but if we can cover 61508 and 26262 that would be sufficient.
