REA prefers that beneficiaries signing the GA are WP leaders. The consortium must have the technical resources needed to carry out the project (so-called ‘operational capacity’). In that regard, the work should be done primarily by the beneficiaries themselves but if needed, they may involve other partners and rely on outside resources (including involving Associated Partners). The fact that beneficiaries retain responsibility towards the granting authority and the other beneficiaries when relying on affiliated entities and other participants (including Associated Partners) does not preclude that an Associated Partner that implement action tasks may appear as work package leader for these tasks. In any case, the operational capacity must be demonstrated in the proposal and be available at the moment of the implementation of the work. Its assessment is performed on a case-by-case basis.
