The design of a support system is complex and requires the involvement of a team of experts from very different fields of research. Because their background, language related to their expertise and methods are sometimes very different, confrontations, miscommunications and frustration may occur within the team. In the worst cases, these problems may lead these experts to work in complete isolation ignoring the expertise of the others. For the success of a multi-disciplinary team, the expertise of each specialist has to be considered complementary to the expertise of the other. Within such a team, it is essential to identify the respective mandate of everyone, their limitations and the opportunities of interactions between these experts. This document presents the TRIAD framework. This framework is composed of three nodes (Task-Tool-Human), which are interrelated to form a network. Specialists involved in the design process are introduced via a specific node of the TRIAD network. This TRIAD identifies for these specialists their axes of expertise (their role and mandate), their hidden axis (their limitations) and the interactions between these experts.
