[...] At the workshop participants worked in separate groups, one per each of the main issue identified in order to suggest specific actions that should be carried by European Commission and by stakeholders (themselves). Here we present the key recommendations that emerged from these groups. Necessarily, because of the method of open engagement, the recommendations do not stem directly and logically from the identified bottlenecks as in a traditional study. Instead, recommendations are logically related to the identified bottleneck but are built around the experience of each individual stakeholders, and later enriched through open discussion. Such recommendations are therefore expected to be methodologically less rigorous than in a traditional study, but more diverse because of the range of stakeholders involved
