The research in entrepreneurship is more and more interested in the phenomena of organizational emergence. Confronted with the complexity of the entrepreneurial process, English- and French-speaking researchers have developed a plurality of theoretical and disciplinary perspectives to understand these phenomena. In France, this theoretical pluralism can be illustrated for example in the framework based on the logic of action ; it is seen by some authors as an open theoretical posture. Some others researchers have proposed the Project-Based View (PBV) to seize the phenomena of organizational emergence. In this article, we compare these two perspectives, which take place in the same posture by overtaking the economic and sociological analysis. The article proposes to take into account the assumptions and proposals of the PBV to better understand entrepreneurial moments and to found the approach based on the theoretical pluralism.
