The image of entrepreneurship as an intentionally planned and rationally orchestrated activity has been challenged by a scholarly interest in which irrationalities, such as passion and improvisation, are recognized to be important. Passion, in particular, can be an important driver of entrepreneurial behaviors. Even if entrepreneurial passion has face value as a predictor of start-up success, empirical research is only starting to explore the various mechanisms through which the effects of passion are channeled to outcomes. Our study contributes to this emerging line of research by suggesting that improvisational activities and, specifically, bricolage, are central to realizing the potential benefits of entrepreneurial passion and to enhancing new venture survival.
