How much Entrepreneurial Orientation (EO) is needed for Long-term Success?

According to the STEP research framework, entrepreneurial orientation (EO) is one key element of transgenerational value creation. EO refers to key entrepreneurial processes in a company, i.e. to the methods, practices and decision-making styles managers use to act entrepreneurially. 3 EO consists of five main dimensions and several sub dimensions. However, there is a puzzle. Many studies suggest that the higher EO, the more successful a company is. But this seems not always to be true. Just think of many of the dot.com firms at the end of the 1990s. Firm members could act very autonomously, the companies were very innovative, took high risks, were very proactive and very aggressive in the market. However, most of them were not able to survive for more than a few years. So how entrepreneurial has a firm to be in order to achieve long-term success?
