Big data could be a "gold mine" for creativity if it is used in the proper way, to this aim, we propose to use content management solutions to improve innovation process. Using ECM (enterprise content management) in the ideation step of the innovation process may enhance the creativity of users to create new knowledge. Organizations have access to multiple information from internal and external sources. This information is present everywhere in the workplace and represent an interesting source of creativity. The access to large databases of information can overwhelm users, in their innovation process, and tend them to return to known solutions which will decrease the creativity. To avoid this situation, we will be coupling the ECM with graphical tools. In this paper, we propose a detailed approach on how to use graphical tools with the ECM by applying the analysis properties from the graph theory in order to be more creative. Then, we present a case study where a team participating in an innovation competition uses our proposed approach at the ideation stage to enhance their creativity. Indeed, we will test this approach to evaluate its effectiveness in the in the 24H innovation competition context.
