The decisions of the supervisory board are not the decisions of individuals or a few, but always the decisions of the entire body. Every decision is preceded by thorough information and discussion. In times of digital transformation and cybercrime, individual supervisory boards are required to engage with these specific topics in depth to be able to participate in discussions and meet the management at eye level. Issues such as the selection and appointment of the management board, as well as the management contract and the compensation system, are also increasingly coming into focus. Peter H. Dehnen and his co-authors use this as a starting point for the second journey through the specific competency topics of the supervisory board. The book offers relevant insights into these areas and provides specialized questions for further self-study.
