In the current economic environment, to learn became the best means, for a company, to be competitive in preserving knowledge and experiments of each collaborator and each team. This leads companies to reconsider their knowledge and know-how sharing, to anticipate competences and their members' training, while managing the changes induced by new practices. Such companies are called learning organizations because they build structures and strategies in order to increase and to maximize the organizational learning. An organizational learning is a process which can be seen as a collective capability based on experiential and cognitive processes and involving knowledge acquisition, knowledge sharing and knowledge utilization. In this paper, we define the concept of organizational Learning and why it is based on a sharing process. To that end, we subdivide it into three sub processes: Individual Learning Process, Social Process and Knowledge Management Process. Then we present our work, (1) the approach MEMORAe whose aim is to support organizational learning; (2) the web platform E-MEMORAe2.0 designed as tool for knowledge sharing in an organizational learning context.
