Die Regeln des Managements

The book offers a wide range of rules, but I wonder what guided the selection process. Are these based on personal experience, research, or a mix of both?

Some rules really resonated with me, especially around communication and trust. Has anyone tried applying specific rules from the book, and what was the result?

The concise, rule-based format makes it easy to reference, but I’m curious about what motivated this approach over more narrative styles.
