Considering dependability requirements in the context of Decision Support Systems

In the healthcare context, decisions are crucial. Therefore Decision Support Systems must ensure a high level of dependability. In order to justify the required dependability level, its requirements must be addressed seriously during the system life cycle. To overcome this issue, our approach is based on Model Driven Architecture to model dependability requirements from the earlier stages of decision support system development. Then, it proposes to map them to functional one in order to obtain integral models. The purpose of this paper is to prove the applicability and the benefits of our approach using a case study of urgent clinical care dashboard which is a project recommended by the National Health Service (NHS) of United Kingdom (UK).
