For business studies, should we stick with 1 or 2 main case studies or use a number of case studies. So for example, in global business - methods of expansion. I could say Hilton provide management contracts to other hotels, Pacific Brands relocated production in 2009 to China, Boral Limited uses FDI and owns production facilities in over 11 countries, Billabong exports to the US and Europe as well as how Dominoes Franchises.
