With the emergence of smart applications multi-disciplinarity is becoming an issue in standards setting, as is the need to involve a broader range of stakeholders in the process. One approach to accommodate these needs is the creation of dedicated multi-disciplinary Working Groups (WGs). Following some theoretical deliberations about today’s standardisation environment in general and the need for multi-disciplinarity in standardisation we present a case study of one such joint multi-disciplinary WG. It turns out that this joint WG is seen as both necessary and helpful by those involved. It also turns out the broader organisational setting needs to be adapted to better address the needs of such joint WGs.
