Over the past years, Service-oriented Architecture (SOA) Systems have been recognized more and more as a serious alternative to common monolithic systems for Enterprise Architectures (EA). An SOA provides a flexible means of effectively mapping business processes to IT processes. However, large IT systems require consistent leadership – IT Governance. For SOAs, governance faces new challenges. A number of different approaches for SOA Governance Frameworks exist, which differ extensively in scope and capability, as most of them are product-driven and developed by software companies. In this paper, we outline and compare existing SOA Governance approaches and present our approach - a Generic Governance Model for SOA.
