During last years the Service-Oriented Architecture (SOA) has increasingly won attention among organizations. The goal of SOA is to enable companies to realize business and technology advantages through the combination of process innovation, effective governance, and technology strategy that resolves around the definition and reuse of services. Tight coupling, proprietary solutions and an increasing number of integration interfaces are the main issues of the enterprise application integration today. SOA provides standard-based technologies and design principles to provide the solution for these concerns, but there is no standardized, industry approved implementation method, which provides structure and organization throughout the development process, available. Serivice-Oriented Einterprise Integration Method (SOEIM) supports the whole process of integration solution development with its life cycle, defining tasks and activities necessary to adapt the service- oriented technologies. It also provides a definition of the architecture that should be used to design the system, and addresses the governance issues.
