The current growth of the service sector in global economies is unparalleled in human history, by scale and speed of the labor migration. Even large manufacturing firms are seeing dramatic shifts in the percentage of their revenues derived from services. The need for service innovations to fuel further economic growth as well as to raise quality and productivity levels of services has never been higher. Services are moving center stage in the global competition arena, especially knowledge-intensive business services aimed at business performance transformation. One challenge to systematic service innovation is the multidisciplinary nature of services, integrating across technology, business, social, and client (demand) innovations.
