Enterprise Architecture, IT Service Management (and Governance) and Service Oriented Architecture are current topics, widely discussed in the information technology departments and professional publications. In addition, many companies have been (or are) involved with the adoption of at least one of these innovations. While each of these elements can be considered in its own right, it is in their relationships, and more or less strong intersections, that interesting opportunities and synergies can emerge, potentially even with some specific issues to manage. The focus of this two-part article is just that: to show the relationships, approaches and operative guidelines related to the synergic adoption in an IT organization and/or in an Enterprise of concepts from the Enterprise Architecture (EA), IT Service Management (ITSM) and Service Oriented Architecture (SOA) domains.
