Small and medium sized enterprises (SMEs) play a key role in the modern market economy. The success of small firms is too a large extent dependent upon strategic decision-making practices. Strategic decisions made by small and medium sized business entrepreneurs form the heart of entrepreneurship and can therefore be considered as essential for the dynamics in the economy. Surprisingly, little is known about the decision-making process within SMEs. As far as we know this study is the first to present an empirically derived typology of entrepreneurial decision-makers. On the basis of a large-scale survey among 646 entrepreneurs, we were able to develop and validate a typology involving five types of decision-makers: daredevils, lone rangers, doubtful minds, informers' friends and busy bees.
