Taxonomy for Evolution of Service-Based System

With the rapid development of service computing related technology, the number of application of service based system (SBS) in enterprise is increasing rapidly. Research on evolution of SBS is becoming more and more important. In this paper, we propose a taxonomy framework for evolution of SBS, which is illustrated from five perspectives: (a) motivations of SBS evolutionary changes (why), (b) stakeholders of SBS evolutionary changes (who), (c) locations of SBS evolutionary changes happening (where), (d) times of SBS evolutionary changes happening (when), (e) support mechanisms in the process of SBS evolutionary changes (how). Furthermore, propagation of evolutionary changes of SBS is analyzed in the paper.
