Services are considered to be one of the key growth areas within local and global economies. Services and Service Design are emerging, crossing, and in some cases redefining disciplinary boundaries. Approaches to Service design have emerged that share HCI commitment to working with and for people albeit in the development of useful services, rather than IT artefacts. However there has been little explicit interaction between the two communities. This workshop will explore HCI’s actual and potential inputs to Service Design activities and vice versa.
