Participation processes arent always done well. As a result, citizens dont get involved with new participation offers, and the initiators give up on launching any future citizens participations. If your are you planning a citizens participation process, these ten principles help you to evaluate and improve this participation process. They provide you with guidance and certainty. They offer you an opportunity to make your participation offer satisfactory and profitable to everyone involved. The ten principles for enhancing the quality of citizensparticipation are substantiated with key questions`and practical recommendations. They are supplemented by a suggested wording for a “voluntary commitment for good citizens participation” as well as a brief evaluation questionnaire with which you can check for yourself whether the quality principles have been adhered to. The principles are valid for all processes of citizens participation: for participation at the municipal, state and national level as well as for participation processes with public or private project sponsors.
