Acknowledgements

This book would not have been written without openness to cooperation of two universities: University of Warsaw and University of Łódź.

My biggest thanks go to two people from McKinsey, who have been supporting my classes on UoW and WUT for years, inspiring it with ideas for new challenges, ideas and solutions. Mateusz Zawisza and Amadeusz Andrzejewski, thank you very much!
