When (re-)designing organizations, one must first be clear about what is meant by the structures of an organization and what can be done in order to change them. In this book, we present communication channels, programs and personnel as central structures. We also unfold the aspects that come to the forefront when one focuses on either the formal, the informal or the display side of an organization. At the core, we elaborate on how structures cause blind spots, and how these can be utilized for processes of change.
