The time has come for better management. But better management is not merely about adding new labels to the current ways of doing things; it is much broader than efficiency and alignment. In this book, Lukas Michel offers senior executives and managers tools to understand a new way of discussing and thinking about management and work, which requires us to take on a broader perspective of the company and its culture. It’s every manager’s prime job to manage better: to change the way they lead people and how they organise work in the new (post\-pandemic) business context. The book discusses the role of the operating system to do that and clarifies managerial priorities and goals. This then sets the stage for Diagnostic Mentoring – the methodology that enables the transformation of the way we manage.
