Requirement engineering in health care and telemedicine.

Requirement engineering (RE) covers activities involved in elicitation, analysis, specification, management and verificationof requirements.All development processesfor safety related systems begin with timeintensive requirement tasks. Especially in the medical sector RE plays a major role as all development activities refer to the previously specified unique identified requirements.Neverthelessmany projects fail due to consequences of underestimated RE activities.Smart Sensor is a project within the “Medical Valley EMN” founded by the German ministry BMBF and industry. The project is structured in five sub projects (Smarts Sensors A to Smarts Sensors E) and one leading project on the top. The project goal is the research of a modular and scalableassistance system and the appropriate services to give peoplein care more freedom and self-determination.Taking Smarts Sensors Aas an example we show how typical RE tasks can be applied even in research and development to focus on stakeholder needs and to bring together all the synergy of a large interdisciplinary project team.
