An interoperability assessment approach based on criteria dependencies to support decision making in networked enterprises
In the networked enterprise, the interoperability is seen as a requirement for ensuring the collaboration among partners. Therefore, an assessment for identifying the enterprise’s strengths and weakness regarding interoperability is paramount. It involves determining the gaps between where enterprises envision themselves in the future and the enterprises’ current states. Indeed, a variety of approaches were proposed in the literature. However, based on surveys, existing methods are assessing specific aspects of interoperability and focusing only on one kind of measurement. The objective of this work is, therefore, to propose a holistic assessment approach to support the interoperability development. To do so, the criteria regarding the interoperability aspects and measurements were identified and are being formalised. The enterprise systems associated with the criteria are being modelled based on Enterprise Architecture techniques. This modelling supports the identification of existing interdependencies between criteria. Finally, case studies will be used to validate the proposed approach.
When Enterprise Architecture Meets Government: An Institutional Case Study Analysis
This study investigates the systemic challenges facing enterprise architecture programs in government. Drawing upon the institutional theory lens from the political science field, a Danish case study is used to explore why public agencies implement enterprise architecture programs and the challenges they face when governing these programs at different levels (vertically) and different functions (horizontally) of government. The analysis shows that enterprise architecture is not just a technical issue, as economic and political facts are equally important when establishing interoperable e-government services. The findings suggest that implementing enterprise architectures in government challenges the way information systems are organized and governed in public agencies. Interoperability challenges in government arise because there is no overall coordination of different information systems initiatives in the public sector and because public organization have no economic and/or immediate political incentives to share data and business functionality with other organizations in their enterprise architecture programs.
Interfaces for Enterprise Solutions
This article compares current and future interface concepts and the dramatic cost implications of interfaces. With the increased importance of exchanging information between enterprise solutions, a coordinated interface architecture should be considered. An interface architecture for the extended enterprise requires a shared communication language, one that standards greatly facilitate. While traditional interface approaches, such as point-to-point and hub and spoke, have been widely deployed in the past, they are costly to maintain and do not provide loose-coupling and fast return-on-investment. Web services and the Enterprise Service Bus (ESB) are promising interface technologies that provide access to loosely-coupled services using commercial standards and existing infrastructure to support a service oriented architecture. Numerous cost drivers, such as the interface architecture and functional, technical, and organizational characteristics significantly impact the cost of an interface. An understanding of interface technology and cost drivers will ensure system architects are better equipped to design and deploy cost-effective interface architecture.
