In this paper we focus on the structure and function of service tasks and a chain of service tasks in late modern global economy. Service tasks and its chain provide basic elements of contemporary service oriented economy that include a traditional supply chain as a special case of fabrication service. We divide service chains into self-produced service chain and produced service chain. The former, for example, includes pedestrian movement at commercial accumulation, shopping area and tourist resort. The later includes ,for example, medical service, care service and tourist service. We focus on a flexible and inter-organizational connection of service tasks that induce co-creative and hyper variety of service oriented industrial structure. We propose three criteria of hyper variety industry as a cluster of flexible service chains that overcomes the demand shortage of developed and mature society. The one is downsizing of service tasks. The second is a flexible connection and re-connection of service tasks. The last one is co-creative evolution of service tasks and continuous creation and recreation of service chain.
