An Integrated Model for SOA Governance
Abstract: The concept of Service Oriented Architecture (SOA) expresses a new idea for organizing a service-basedbusiness environment. However, without wise governance, SOA fails. Therefore, this study focuses on theelucidation of the following issues: What are the critical roles of SOA Governance that promotes theattractiveness of a service-based business environment as well as what factors can inhibit the role of SOAGovernance? The primary objective is based on the believe that an integrated model of governance can improvethe understanding of people, i.e. stakeholders, in their efforts to establish a comprehensive architectural patternthat coordinate any effort aiming to make service-based business environment attractive.This work elucidates the roles of SOA Governance. Accordingly, the primary and most significant role of suchgovernance is the establishment and management of a negotiated and accepted SOA. The equivalent crucialsecond role of such governance is to use the established architecture and coordinate every related effort thatpromotes the attractiveness of an architected reality. In this sense, the service oriented architecture follows thewisdom of such governance. In the same sense, any effort that change the service-based business environmentof business follows the premises of the established service oriented architecture. Therefore, we can concludethat the wisdom of SOA Governance promotes the attractiveness of a service-based architected environmentFurthermore, the work indicates that there are three main factors that inhibit the role of wise governance. Firstly,a fuzzy, inconsistent, incomplete, ambiguous terminology upon which the concept of SOA and SOAGovernance are described, designed, evaluated, etc. Secondly, conflicts of interests and contradictory core ideas,such as alignment, agility, reusability, efficiency, etc. provided by different disciplines, i.e. SoftwareEngineering, IT Management, Enterprise Architecture, etc., that inhibit the choice of a comprehensivearchitectural style for a service-based business environment. Lastly, the plethora of interesting but otherwiseisolated and incomplete models of both SOA and SOA Governance create a sense of uncertainty, and therefore,create the need for endless process of acquisition of information. In the face of these critical issues that inhibitthe role of wise governance, our study has developed an integrated model of SOA Governance aiming to clarifythe relationship between governance, architecture, and service-based business environment. The model has beentested empirically with acceptable and fruitful results.The above conclusions may be seen as a result of an adequate approach of inquiry consisting of three mainstages. Firstly, a theory that shapes every part of this study. Secondly, the creation of a better and moreintegrated model (framework) for SOA Governance derived from the distillation of large volume theoreticalideas and models. These theoretical ideas concern both the characteristics of SOA and the wisdom of SOAGovernance. Lastly, a fruitful comparative understanding between theoretical and empirical views of SOAenvironments with respect to identified issues of both SOA and SOA Governance. By this way, we have testedboth the validity and reliability of the proposed model. In any case, we do not say the proposed model iscompleted both theoretically and empirically. What we say is that it is a promising idea to develop further theresult of our effort.
