This master thesis treats with the challenges which EU supported projects include. The applicants have to submit the project idea in a defined time space to the EU commission. The applicants have the possibility to do the projects with partners which also have to fulfil duties during the project. The challenges of an EU sup-ported project are, that for bigger companies it is much easier to handle an EU project because the effort is very high and for smaller companies it could be diffi-cult to handle this beside the normal business. Furthermore the possibilities how the remaining financial resources can be found are discussed, because the EU just supports a maximum of 50% of the project sum. The knowledge of the theory was proven by interviews with people who have already done EU projects. In the interviews was shown that external consultants are involved, because of the chal-lenges and effort which an EU project provides. These consultants are specialised to support the companies during the projects in different things. The result of the master thesis shows that the effort and the challenges are extreme.
