Abstract
Service activities are basis of human living and should be treated as complex systems including mutual interactions of various players. The value of services should be evaluated from multiple perspectives such as customer satisfaction, employee satisfaction, profitability, or social value perspectives. We propose the service benchmarking method based on service engineering, by which service providers can learn their strong and weak points through inter- and intra-industry comparison. This paper discusses how we could support service providers to re-design sustainable service systems with actual data obtained thorough service benchmarking.
