Can we name the deliverable “Awarding of doctoral degrees” (Table 3.1b in Part B) “Enrolment of all researchers in a programme leading to the awarding of a doctoral degree”?

This option is fine. It is important to clearly state that all fellows will be enrolled into doctoral studies. It is quite difficult for beneficiaries to commit to the awarding of a doctoral degree to each recruited researcher at a specific date, given that the PhD programmes duration can be different from an institution to another and that unpredictable events can delay the PhD thesis completion.
