9. Regulatory Working Group Work Done Tasks 2+5 finished with a document for Guidance and Graded approach But: The planned review of the application cases (Task 1) could not be done as those weren’t available during the CRAFT project. Instead, the Regulatory Working Group provided support for the other Working groups especially for the to be written test cases.

10. Regulatory Working Group Work Done For Task 4 the Regulatory Working Group provided guidance and support for the discussion esp. for the SAFRAN Tool. But: For the comprehensive recommendations the input from Task 1 is necessary. Therefore inputs coming from the test case reviews will enable the Regulatory WG to complete Task 4.

11. Regulatory Working Group Work Done Task 3 was identified as no addressable in the CRAFT project workflow. But: As discussions showed that this is still an important working field, it was recommended to either address this in a follow up project or instigate a stand-alone project later.
