Who decides and how can good decisions be taken? For a long time, this question did not even arise in many hierarchical organizations. In case of doubt, the decision is up to the boss or a small high-ranking leadership circle, which in the best case features a high degree of diversity and honors disagreement but which in the worst case scenario only consists of claqueurs. As more and more organizations try to become more agile, new answers to the question of who decides and how to decide are of central importance. After all, agility means subsidiarity, i.e. that decisions must be made as decentralized as possible in self-organizing teams. Only how?
