This book is intended for readers who want to try out collegial leadership and agile self-organisation in a very practical way - either in their own organisation or by providing external professional support for an organisation. At the same time, coaches and organisational developers, who already have specialist systemic experience, will probably be able to make much greater use of the systemic principles and the technical terms we use in the book. Claudia Schröder and Bernd Oestereich work holistically with the organisation at all levels and lead with a sure hand through a process of comprehensive change. They have a sophisticated compendium of collegial management tools with which the decisions always remain with the organisation itself. Eva Schad, Managing Partner for David Chipperfield Architects Berlin Collegial leadership is an agile concept that structurally enables self-organisation and participation. It is based on a humanistic view of people and individual and organisational learning processes. The framework and the practical tools support us in trying out distributed leadership work.
