Porter’s Five Forces model is a powerful management tool for analyzing the current industry profitability and attractiveness by using the outside-in perspective. Within the last decades, the model has attracted some criticism because of the developing Internet economy. Due to an increasing significance of Digitalization, Globalization and Deregulation, the industry structure of the ‘Old Economy’ changed fundamentally. The ‘New Economy’ is not comparable with the ‘Old Economy’, which is the basis of the Five Forces model. Moreover the last decades have shown that Information Technology became more and more important. Nowadays Technology is one of the most important drivers for change and not only important for the implementation of change. Today new technology is one of the most important drivers for change. Furthermore Porter also couldn’t take the growing significance of ‘Government Deregulation’ into account. In 1979 the government was able to regulate the market by defining and enforcing “property rights and the rules of competition”. In the past 20 years, governmental influence on industries decreased steadily. Therefore the most of the concerned industries (airlines, communication, or banking industry) were able and constrained to search for alternatives and to structure their business in a new way.
