Determination, Prioritization and Analysis of User Requirements to Prevention Apps

With the digitalization of the health care system, health apps are taking on a new role as potential helpers for doctors and patients. For the acceptance of these digital solutions, however, it is necessary to know the requirements of the users in order to satisfy their needs. Aims of the conducted survey study were to determine, prioritise and analyze requirements for applications in the field of prevention and health promotion on the basis of the Kano model of customer satisfaction. In a first step, user requirements were identified by expert interviews. In the following, 160 participants took part in a questionnaire survey based on Kano model and identified user requirements. The results show 10 different product requirements evaluated by the participants using the Kano method resulting in important in-sights into the requirements from user perspective. The wishes for individualization can very clearly be classified as a performance criterion and data protection as a basic requirement. Disproportionate satisfaction can be achieved through communication with the doctor or with usage of reward systems within an app, while reminder functions were seen indifferent.
