The “Touchpoints and Engine concept” is the high-level description of REACH system architecture. It further guides the detailed structures of the REACH system architecture and its subsystems. With the “Touchpoints and Engine concept”, the REACH´s so-called product-service-system architecture is divided into six manageable research and development clusters: four clusters of “Touchpoints (TPs)” that represent tangible connections between users (seniors, informal/formal caregivers, or physicians etc.) and the REACH system; one “Engine” cluster which is a cloud-based digital platform; and one “Interface” cluster which is composed of a set of specifications that allow Touchpoints and other products/services to connect/interact with the Engine. Each cluster is associated with a dedicated and independent development team coming from the project consortium members.
