Most excellent business schools have for a long time ascribed to an actionoriented philosophy of management education. This philosophy argues that students of business must do in order to achieve proficiency, and that managers succeed or fail not so much because of what they know, but as a result of what they do. This case book by two IMD professors is based on this philosophy, as well as their twenty years of management education experience. The collection of twelve cases are pedagogically sound, appealing to the class participants, stimulating to teach, and focused on the essential problems of managing firms going international. The twelve cases are based on indepth field research and close collaboration with the managers and companies described.
