(en) In a context of technological change, of matrix organizations and networks, companies strive to harmonize, structure and improve their management processes and systems. One means for this is to implement an ERP, that is a system intended to process management information instantly within the organizational network, with the hope to improve performance. However, investments in ERPs do not bring out automatically organizational performance. Sometimes, the return on investment is far below expectations, which causes managers disappointment and questioning about the relevance of technological choices carried out. Based on theories analyzing interactions between technology and organization, this thesis questions "appropriation processes" of an ERP within companies. It analyses the links between process management, training logic and appropriation of an ERP by users within the firm. Training organized on the ERP for personnel in the firm is considered as a social construction that can adopt very different types of approach, either instrumental or integrative (according to the process of change management conducted within the company). As a result, contrasted types of appropriation can occur, related to what type training logic has been put in place. Carried out within firms set up in Belgium, this research shows that, beyond all technological determinism, the change process is the determining factor regarding outcomes. Managers have various choices as regards the degree of involvement of ERP users in change and in training. However, if those choices are sometimes slightly weighed up because of short deadlines in the implementation of the ERP, they have a determining role in the final appropriation of the ERP within an organization and consequently in its final outcomes.
