optimisation d'un processus de conception par quantification de l'usage

Abstract : The medical devices make up a specific group beside classical products by their actions on the patients’ health. By this indication, the use of such devices potentially induces risk on the patients’ health especially in case of failure or misuse. These products may be used by a large target of users themselves or assisted. This diversity in terms of references and possible use, combined to the critical aspect of these products implies a significant taking into account of the user and usability during the product design. This is all the more important because as the medical devices form a very innovative industrial sector linked to the technological advances. These developments need to be adapted to the users who do not have always all the knowledge needed to their use. Nevertheless, while the framework (standards and regulations) emphasis on the need to take into account the user, this approach is little implemented by the companies which are, for a large part, SME’s with limited resources. At the same time, some weaknesses about the tools and methods in matter of use analysis are present. Moreover, this approach collides with barriers induced by design habits, multidisciplinary context and constraints related to the medical field. In the aim to give a realistic industrial answer to implement the user into the design process, a quantification tool of usability was developed. This tool draws on measurement methods and dedicated results presentation towards designers and General Public. From the experimentations, the proposed index appeared consistent against a gold standard index (SUS) and adds more details in the results (tasks, panel priority about usability components). These feedbacks showed a high understanding level of this tool and a significant interest by the designers but also the General Public. In addition, the experimentations highlighted the positive contribution of the proposed tool in the design team communication but also in the design choice by implementing usability approach including the upstream phases, especially in creativity.
