Brilliant. The story is just amazing and it definitely illustrates the difference in problem solving approaches. However, I would like to add that XLRI, Jamshedpur has two courses for its PGCBM programme which cater to the comparison between these different styles. They are called as ' Organizational Development' and ' International Management.' I am an alumnus of this programme. I can very well say that these two courses cater to the different styles not only in Japan and US but also European firms. They are very much contemporary and the method, obviously is Case Study.
