Service is defined as a provider-to-client co-production that creates and captures value while sharing risks. By collaborating people，resources and techniques from customers and providers together，a service system co-produces and delivers proposed values to all the participants of the service. As value holds a central position in lifecycle of services，it should be fully considered and aware of in full lifecycle of a service and it is very essential to be conscious of characteristics of values. This is the objective of this paper.
