Bringing together the ICT and the business layer of a service-oriented system (SoS) remains a great challenge. Few papers tackle the management of SoS from the business and organizational point of view. One solution is to use the well-known ITIL v.3 framework. The latter enables to transform the organization into a service-oriented organizational which focuses on the value provided to the service customers. In this paper, we align the steps of the service provisioning model with the ITIL v.3 processes. The alignment proposed should help organizations and IT teams to integrate their ICT layer, represented by the SoS, and their business layer, represented by ITIL v.3. One main advantage of this combined use of ITIL and a SoS is the full service orientation of the company.
Enterprise architecture supports organizational engineering in many ways. Service orientation is regarded as dominant operations model for service providers -- within and beyond IT. As a consequence, it is important to integrate service management and service orientation into enterprise architecture. This paper proposes an enterprise architecture extension that achieves such an integration. IT service management is defined according to ITIL. Based on the integration of service management into enterprise architecture, the integration of Service Oriented Architecture is discussed as a further extension. The research is based on the Business Engineering approach and the guidelines of Method Engineering. : Enterprise architecture (EA) is a new approach that organizations should practice to align their business strategic objectives with information and communication technology (ICT). Enterprise Architecture encompasses a collection of different views and aspects of the enterprise which constitute a comprehensive overview when put together. Such an overview cannot be well-organized regardless of incorporating a logical structure called Enterprise Architecture Framework (EAF). EAF presents a transparent and comprehensive map of an organization that shows how all organization elements (business and IT) work together to achieve defined business objectives. Several distinctive EAF have been proposed, but many organizations are struggling with using these frameworks. This article try to eliminate the challenges of common and famous EAF by using Service Oriented (SO) paradigm. This service oriented EAF (SOEAF) named KASRA EAF. KASRA EAF involves a SO Roadmap that is compatible with ITIL and a Classification Schema comprises four rows and six columns.
