The contribution of this paper is the development of a research model around the impact of SOA on BPS in terms of achieving fundamental efficiency and flexibility potentials while covering both the business layer and the IT layer of the firm. Drawing on an accepted and widespread enterprise architecture model, we derive propositions that explain why and how SOA’s characteristics help to standardize business processes and how the interplay between SOA and BPS leads to an increased overall business value. Additional moderator arguments, such as the level of service granularity, the centrality of SOA governance, or Business IT alignment, are added to the research model as critical success factors of achieving business value of SOA.
