Division of labour, information processing, internet, cloud, mobile, smart data...we get new technical support almost daily. We can delegate more and more tasks to machines and thus dedicate ourselves to more and more complex tasks. This changes our work drastically. Working through routines - alone at the desk - is becoming less frequent. Teamwork, communication, problem solving, creativity and speed become normal. The working environment has an enormous influence on this new way of working. And for employees and applicants, the importance of the working environment in choosing an employer is constantly increasing. This book is aimed at all (managers, from team leaders to CEOs) who have recognized this and want to act now. It offers them inspiration and argumentation help. And it is for all those who now want to leave Dau.
