In professional settings, people often have diverse and competing conceptions of responsibility and of when it is fair to hold someone responsible. This may lead to undesirable gaps in the distribution of responsibilities. In this paper, a procedural model is developed for alleviating the tension between diverging responsibility conceptions. The model is based on the Rawlsian approach of wide reflective equilibrium and overlapping consensus. The model is applied to a technological project, which concerned the development of an in-house monitoring system (...) based on ambient technology. The development of this innovative technology raised questions among the technological researchers about its social acceptance and the way issues related to privacy and security should be addressed. The case is analyzed in terms of two procedural norms (reflective learning and inclusiveness), which are based on literature on policy and innovation networks. Analysis of the case shows that, in a pluralist setting, a procedural approach can be useful for encouraging discussion on the legitimacy of different responsibility conceptions and the question what a fair responsibility distribution amounts to.
