With regard to the new EU-Funding period 2007-2013 the Development Society Ostholstein as the german part of the common Interreg-Secretariat for the Fehmarnbelt-Region had engaged DSN and their danish co-operation partners Epinion A/S and Advance/1 to evaluate the future Interreg IV A-Programme. The prime objective of the evaluation was to increase the quality, efficiency and coherence of the fundings' Interventions and to improve the implementation of the operational programme (Interreg IV A). The impact of the programme had to be evaluated in the face of strategic objectives of the European Union and of the specific structural problems of the concerned member countries and regions cosidering the requirements of a sustainable development.
