The authors propose a longitudinal case analysis of two Tuscan medium-sized companies in the fashion industry with the objective to verify if and how the recent international economic crisis has affected the business models and marketing strategies of the two companies. For this purpose a theoretical model is developed for the analy- sis of business models and the relative evolution that the authors use as a framework to design the case study method. The empirical results show that medium-sized firms react to the crisis by adapting their strategies to a different competitive scenario; the original business model remains the same, but some changes in its critical sub-systems have been introduced.
