RISE: Is it necessary to include an SME in a RISE?

The participation is very varied related with Non-academic sector but the Large Companies are more common in RISE consortiums. The number of SME participation in funded RISE projects in 2014 it was 37participations with 4,2 M€ requested and only 3 SME are coordinating RISE projects. The SME participation is very important but it is very hard to involved them when their staff is limited.
