Competence management has recently become an important issue in companies. Closely related to knowledge management, it considers the capacities of an individual to perform by using his/her knowledge. This knowledge management becomes a tool for companies to manage human resources in the long run. The ability to characterize useful competences, to evaluate how they are improved through past experience and successive jobs occupied, and thus to select project team members according to fully or partly existing skills are some of the concerns that business managers have to tackle. This paper focuses on the coordination of design activities in order to propose a tool dedicated to project managers on an operational level to manage skills for better team building. The aim is to improve team performance in the short and long term while preserving a link with the human resources department. Our work is based on the results of the ATLAS project which studies the coupling between systems design and management. We propose an initial tool to manage skills in a design project.
