Scenario-based Requirements Elicitation in a Pain-teletreatment Application

This paper proposes a way to elicit requirements in the domain of eHealth, in particular telemedicine treatment, that is in alignment with the evidence based working practice in medicine. In collaboration with ICT developers, medical professionals co-shape the intended system, which has to support the telemedicine application. These professionals develop a scenario and provide feedback to the subsequent requirements elicitation process which is based on the developed scenario. We propose a mix of methods and techniques to elicit requirements holistically to achieve the previously mentioned alignment. The requirements elicitation applies basically a top-down scenario based approach, however complemented with additional methods to overcome the inherently incompleteness of scenarios. In the proposed approach, we for example analyze treatment tasks and their goals that are not only identified or inferred from the scenario but also from the treatment protocol defined in an associated treatment trial design. This paper only addresses the early phase of requirements engineering, later phases, which require refinements of associated use cases, are beyond the scope of this paper.
