Enterprise Architecture, IT Service Management and Service Oriented Architecture: relationships, approaches and operative guidelines (part 2 of 2)

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.

Service Oriented Architectures: The State of Play in Australia

The notion of Service Oriented Architectures (SOA) has received considerable attention in the commercial literature over the past two years, but a consistent definition of what an SOA really is, and what it does, has yet to emerge, and almost no empirical research has been conducted to find out what SOAs means to the IT practitioners charged with implementing them in businesses and government organizations. This study attempts to address this gap by reporting on the results a qualitative research study conducted to ascertain what service-oriented architectures meant in practice to the IT practitioners working on them in 23 large Australian organizations. The findings are then used to draw some conclusions on how SOAs can be expected to evolve in the organizations in the future.

EA: It’s Not Just for IT Anymore

Enterprise Architecture, widely used in commercial ventures and federal agencies, has been viewed primarily as an IT discipline and has been relegated to the office of the Chief Information Officer or the Chief Technology Officer. In this paper, the authors argue that EA has the potential for far-reaching impact on an organization’s “bottom line.” In many organizations, the EA is the only repository of enterprise-wide abstractions of the business. To begin to realize its potential, the EA needs to be exploited by enterprise management processes and should be organizationally re-located where its influence can be far more pervasive. By positioning the EA as a repository for enterprise management, it can integrate discrete business operations and strategies to enable a more efficient, more agile organization.

The District of Columbia’s City-Wide Enterprise Architecture

The District of Columbia’s Office of the Chief Technology Officer (OCTO) recently completed a set of Citywide Enterprise Architecture (EA) blueprints that illustrate IT systems and enterprise business processes with a near-term focus of the nine Services Modernization Programs (SMP). The Citywide WA is compliant with the Federal Enterprise Architecture Framework Level III. The Citywide EA is comprises four blueprints: business architecture, information architecture, application architecture, and infrastructure architecture. The Citywide EA application blueprint comprises a Services Oriented Architecture for hared software components. Three of these EA blueprints will be published in the District’s IT Strategic Plan 2005-2008. The fourth viewpoint, infrastructure architecture, is classified as Protected Critical Infrastructure Information by the U.S. Department of Homeland Security. In addition, the District is designing long-term Concepts of Operations that constitute strategic program plans and target architectures for each SMP. The District’s to-be planning approach incorporates best practices from Business Process Reengineering and EA.
