The trends and strategic issues facing the company stem primarily from the complexity of the environment, which manifests itself in uncertainty and ambiguity. In this perspective, the challenge for the company's managers is to be able to identify and understand this complexity, in order to better manage it thereafter. One of the levers to manage this complexity is economic intelligence. In the absence of relevant models capable of supporting decision makers in such a challenge. The author writes a book entitled "Economic intelligence in the company: an analysis by process" which allows to clarify these articulations through an emphasization of the role of the economic intelligence as a process of creation of the knowledge. This work is the result of a doctoral thesis in management sciences, conducted at the University of Aix-Marseille under the direction of Mrs. Alice Guilhon, General Director of the Skema School (Ex CERAM Sophia Antipolis) and Mr Abdenbi Louitri, Professor of Higher Education at Cadi Ayyad University.
