In fast changing environments, companies and organizations have to continuously adapt their operating principles in response to new business or collaboration opportunities in order to remain competitive. The growing demand for high-quality services is taking organizations to format their operations to offer more personalized service packages and seek collaboration with other stakeholders. Moreover, provision of personalized services depends on frequent contextual information analysis. In the case of elderly care, the use of assistive technology is expected to have a positive contribution to the diversity of required services that support aging well. Demographic trends show that the percentage of elderly population is increasing, while ageing entails several limitations, calling for assistance services adapted to the specific needs of each person. These needs can evolve along the ageing process, requiring an evolution of the care services. In this paper, we make an overview of related concepts and propose a personalized and evolutionary care services model supported on collaborative networking, context-awareness and Internet of Things.
