Résumé
Stevenson and Jarillo (1990) and Stevenson (2000) introduced the concept of entrepreneurial management to describe the phenomenon in which existing organisations pursue opportunities. Since these works, the literature has focused on different types of opportunity (particularly created opportunities or existing opportunities) and on differentiated modes of pursuing opportunities (identification or construction) (Short and al., 2010), without treating the organizational topic. This research focuses on the different modes of management depending on whether the opportunity comes from a construction or an identification process. In response to this issue, we formulate propositions based on the. The relevance of these propositions is evaluated using a qualitative study. The results suggest that there is a relationship between the nature of opportunity and the organisation's mode of management. However, analysis of the various characteristics of management suggests that the systematic opposition of entrepreneurial and bureaucratic management styles is not always pertinent. Firms tend to use several different styles of management jointly. Finally, we will also discuss the characteristics of the process and the relationship between opportunity construction and identification.
