The evaluation of the interactive systems has been the subject of numerous researches during the last two decades. However, it still remains a difficult task to establish. Generally, evaluators exploit a single method to proceed to an interactive system evaluation. However, many authors assert that a single method is not enough to obtain relevant evaluation results. As a solution, we propose a decision-making approach for the synthesis of data collected by different evaluation methods to obtain more reliable evaluation results. The proposed approach is based on three evaluation methods: the questionnaire, the ergonomic quality inspection and the electronic informer. As an evaluation result, the proposed approach provides evaluators with the quantification of the evaluation dimensions: the usability and the system functionality degree.
