Development of two-layered service evolution map: Structure and development process

As digital convergence has proliferated and multi-functional products have become prevalent, services that utilize product elements such as technologies, functions, and data of products have been increased. Such a phenomenon continues to accelerate with the diffusion of intelligent products like smart phone and open markets for applications, which is boosted by success of iPhone and Apple App Store. Despite the increased importance and attention, however, little attempt has been made to investigate services based on the utilization of product elements. In response, this study proposes a two-layered service evolution map and the development process as a tool for analysis of evolutionary pattern of services based on the utilization of product elements. The proposed service evolution map consists of two layers with the time dimension: product element layer for utilization pattern of products and service layer for evolutionary pattern of services. Based on the service documents describing what the services are, co-word analysis and modified formal concept analysis (FCA) are employed to develop product element layer and service layer, respectively.
