With the growing number of senior citizen, Europe is going to face major challenge to deliver care for them. The OLDES project funded by the Information Society Technology Programme of the European Union is exploring how ICT can help in the cost-effective scaling of the care delivery while also improving the well-being of elderly people. Designing a caring system is intrinsically complex because of the personal dimension and the many stakeholders involved across multiple organisations boundaries with different cultures.
This paper describes the approach taken in OLDES to produce a design able to cope with the needs of the various stakeholders. Rather than following a traditional ”requirements to design solution”, a co-constructive approach was taken where the multiple actors, including patients, carers, social services, services managers were involved. A distributed animation tool was used to support this approach, enabling validation through various graphical representations of the system behavior. The resulting platform still, under development, will be tested in two major European towns : Bologna and Praha.
