The Uppsala model is one of the theories describing the internationalization process of firms. The model states that firms first choose to enter nearby markets with low market commitment. We found a case where the firm did not follow the model. Thus, it is not applicable to all firms. By conducting an anomalistic case study of Malmberg water AB the model has been critizised and modified. Three firm specific aspects have been added to the original model. These are, size of the firm, competitive advantage and the product. By adding these new varibles to the original Uppsala model we hope that it can better explain the internationalization process of firms and especially the psychic distance concept. However, this needs to be further tested and evaluated.
