Work packages "WP" detail the different parts of the project. They are characterized by different tasks, coordinated by WP leaders. Each WP task is consistent with subjects, activities and methods oriented towards different aspects of the project: Coordination, Research and Dissemination. The different WPs are related and form an organic picture defining the entire project structure. They represent a tool for defining the project organizational as well as managerial strategy. The roles and resources provided by the different partners plus their interaction and activities are in fact considered in the WPs structure and WPs tasks definition.
