International audienceEvery interactive system has a functional part and an interactive part. However the software engineering and the human-computer-interaction communities work separately in terms of methods, models and tools, which induces a work overhead for integrating the results of these efforts, as well as increased inconsistency risks. We endeavour to treat this problem by proposing a design method, which couples the functional kernel and the interaction design. In particular, this method proposes a specific way of structuring the interaction and the business spaces. The structure is based on components called Symphony Objects. In this article, we attempt to evaluate the technical aspect of a Symphony Object model issued from the method by measuring its implementations with software metrics
