The adoption of the service-oriented architecture (SOA) paradigm represents one major reconfiguration challenge of enterprises. It requires to break down business processes and resources, and to consequently disintegrate entire Information Technology (IT) environments. Thus, the implementation of a SOA can present serious challenges to professionals working in an organization. Not much is known so far about the process by which individuals seek to evaluate the potential impact of SOA paradigm in their business. Most decisions nowadays are done without a systematic analysis of the current situation. Those decisions often come with too high expectations about a success of a service-oriented application environment. Furthermore the necessary efforts to realize the SOA paradigm for the own business processes is often not systematically estimated and therefore not included into a comprehensive cost-benefit analysis. We present a methodology to develop a conceptual model of the enterprise by which individuals might assess the impact of a SOA before an IT implementation. The paper provides insights into how and why managers should react to the given challenges. The model recognizes that the dynamic readjustments not only impact on the business task level, but also on the organizational level of work tasks and role relations. The model provides a starting point for a further study of the evaluation criteria for professionals using a SOA.
