In this paper, we intend to take a further examination on service science as a new discipline in terms of a structurally anatomic analysis. We consider that such analysis will contribute to a better organization and advancement of this subject as a typical interdisciplinary one but little has been done so far. We propose a two layer structure to describe service science where the lattice structure is used to depict the four parts and their interrelationships at the upper layer that leads to a four interlinked sub-topics frame for the lower layer.
