The impetus for the development of a specific quality system the understanding that existing quality and project management systems, mainly having originated in a technical field, can not be unconditionally transferred to health promotion and prevention projects. A system was called for that could account for the complexity of setting oriented intervention projects. At the same time, values and principles of health promotion were to be explicitly considered. The first developmental phase was realized at the Institut for Social and Preventive Medicine of the University of Zurich, on behalf of and in close collaboration with the Swiss Federal Office of Public Health. The basics of the quality system were elaborated in collaboration with scientific experts and experts with practical experience and in May 2000 the first online version became available. In 2001, Health Promotion Switzerland was commissioned for the project and continuously developed the quality system and services.
