Citizen report/planning cell (Bürgergutachten/Planungszelle) is a decision aid method for representative democracy. Sometimes politicians want a project but don't know how to get it started into the right direction. In such situations it's a good idea to ask the impacted community or a representative group from that community.
The citizen report project starts with inviting a randomly selected group of 25 citizens. They'll gather for a week to learn about the political subject and have the chance to discuss in small groups of five (planning cells) with each of the invited main experts and politicians. Minutes are written about the planning cell discussions and the plenum sessions. The essence of these discussions will be written down as citizen report, a handbook for the politicians' decision-making.
