The innovation is nowadays the master word of competitiveness. Inside of innovation the design process is the most constitutive. Starting from the limits of classical design and user centered design we study the needs for the best practices in innovative design. Essentially these practices would be based on situated action (the goal of the innovation is unknown), multiple actors (including the users of course but also the different practitioners in human factors and project managers) and evaluation along the life cycle of design. The best way to reach these objectives seems to mix and adapt some formalized models from the participatory design and creative design as TRIZ. The paper describes a management method for the participatory design based on a graph organization and?UML description. This method is not a task planner, what would be not feasible in design domain, but a control in the running of work so as to return this phase of the life?cycle of a product, controllable and effective. The method is based on ?moments? which are elementary and generic granules of activity; valid for all the tasks of user centered design. From these tasks the method proposes an evolutionary management formalized by graphs of states, the transitions of which are controlled by logical and temporal operators under certain conditions. So the actors as the project manager can have access to all the documents, the procedures,?etc., which they need to work or in collective session or in an individual way. The process of capitalization is also integrated into this plan, what allows reusing the know-how acquired for the other projects but especially to avoid the occasions, the questioning or the rehearsal in the design process. The paper concludes on the realization and the efficiency of the method, especially in case of breakdown innovation but also in dominant design due to the tools developed around the method which facilitates the management and the knowledge retrieval.
