Interdependency is one of the constants of business. Businesses form complex networks for the exchanging of goods and services. Service networks models represent the interconnections among companies, their parts and individuals in terms of services that are provided and consumed. A service network model is a representation of these interconnections. Due to the size of nowadays service networks, their models tend to grow very large. The effective management of service network models requires methods to limit the amount of data presented on the basis of what is needed. This paper identifies a hierarchy of views on service network models, namely offering-centric views, participant views and multilateral views. The offering-centric views focus on one service that is offered by one participant. Participant views present the entirety of the data related to one participant. Multilateral views represent the data regarding a set of participants. We identify the correlations between these views and the mechanisms to aggregate and project them from each other and from service network models. The concepts and mechanisms represented in this paper are explained on a running example based on the automotive industry.
