Should a leader ideally have studied management? Or law? Or perhaps mathematics? Ulrich Hirsch, the head of a consulting firm, and Gunter Dueck, IBM's chief technology officer, have invited mathematicians from top management and politics to share their insights. They discuss personal experiences and reflect on what makes them unique as mathematicians in leadership roles. Surprisingly for many, it has to do with a more intuitive way of thinking! This book is not about the ubiquitous technical mathematics of numbers today, but rather about the formulas for success in real life: mathematical management thinking and action should have a place in every top management team. Why this is the case is illustrated in a very vivid, inspiring, and sometimes amusing way in "Management by Mathematics.".
