One of the major criticisms of EC funding is the complication of funding, rules and paperwork. Horizon 2020 seems a huge merger of activities which have been funded in FP7 under several different programmes, and generic rules are being developed in order to create substantial simplification for participants.
Horizon 2020 will address the call from participants around Europe for a pragmatic shift towards administrative and financial simplification and states that the management of European research funding should be more trust-based and risk-tolerant towards participants.
Simple funding rules should reduce the administrative costs for participation and will contribute to a reduction of financial errors so good news all round!
