| dc.description.abstract | The concept of Service Oriented Architecture (SOA) expresses a new idea for organizing a service-based
business environment. However, without wise governance, SOA fails. Therefore, this study focuses on the
elucidation of the following issues: What are the critical roles of SOA Governance that promotes the
attractiveness of a service-based business environment as well as what factors can inhibit the role of SOA
Governance? The primary objective is based on the believe that an integrated model of governance can improve
the understanding of people, i.e. stakeholders, in their efforts to establish a comprehensive architectural pattern
that 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 such
governance is the establishment and management of a negotiated and accepted SOA. The equivalent crucial
second role of such governance is to use the established architecture and coordinate every related effort that
promotes the attractiveness of an architected reality. In this sense, the service oriented architecture follows the
wisdom of such governance. In the same sense, any effort that change the service-based business environment
of business follows the premises of the established service oriented architecture. Therefore, we can conclude
that the wisdom of SOA Governance promotes the attractiveness of a service-based architected environment
Furthermore, 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 SOA
Governance 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. Software
Engineering, IT Management, Enterprise Architecture, etc., that inhibit the choice of a comprehensive
architectural style for a service-based business environment. Lastly, the plethora of interesting but otherwise
isolated 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 inhibit
the role of wise governance, our study has developed an integrated model of SOA Governance aiming to clarify
the relationship between governance, architecture, and service-based business environment. The model has been
tested empirically with acceptable and fruitful results.
The above conclusions may be seen as a result of an adequate approach of inquiry consisting of three main
stages. Firstly, a theory that shapes every part of this study. Secondly, the creation of a better and more
integrated model (framework) for SOA Governance derived from the distillation of large volume theoretical
ideas and models. These theoretical ideas concern both the characteristics of SOA and the wisdom of SOA
Governance. Lastly, a fruitful comparative understanding between theoretical and empirical views of SOA
environments with respect to identified issues of both SOA and SOA Governance. By this way, we have tested
both the validity and reliability of the proposed model. In any case, we do not say the proposed model is
completed both theoretically and empirically. What we say is that it is a promising idea to develop further the
result of our effort. | en |
