Changes and innovation within service industries, and in the role of “service” across all economic activities, are discussed in the light of technological and social change. Ian Miles graduated in psychology from the University of Manchester. After working at the Science Policy Research Unit (SPRU) at Sussex University for eighteen years, he joined PREST in 1990. His research interests and methods are wide-ranging. Much of his work on technological innovation has concerned new Information Technologies, and he has been particularly interested in service industries as users and sources of innovation. IT is especially important for these industries, but other technological and organisational innovations are also highly relevant. Apart from analyses of services in general, Miles is particularly associated with Knowledge-Intensive Business Services (KIBS), pioneering research into these industries. Research covers both magaerial and policy dimensions of these issues, and uses tools such as case studies and survey analysis.
