Enterprise architecture is a young, but well-accepted discipline in information management. Establishing the effectiveness of an enterprise architecture practice, however, appears difficult. In this paper we introduce an Architecture Effectiveness Model (AEM) to express how enterprise architecture practices are meant to contribute to the business goals of an organization. We developed an AEM fo...

This paper presents an architectural model that enables the convergence of the interoperability of Enterprise Architecture (EA), Service Oriented Architecture (SOA) and Cloud Services. As per the reviewed literature by the authors, there is a lack of research in this space of cloud computing. Hence the authors' research developed an innovative solution to provide a ‘plug and play’ architectural...

This paper describes the design and delivery of a new course introducing the joint topics of enterprise integration and enterprise architecture. Planned for an Information Technology curriculum, the course sits at the crossroads of Computer Science and Information Systems and is intended for upper level undergraduate and graduate students pursuing degrees in any of these three disciplines. The ...

Enterprise Architecture deals with the structure of an enterprise, relationships and interactions of its units. It provides a holistic approach to reconcile IT and Business concerns in an enterprise. Virtual Enterprises are collaborative ad-hoc alliances of multiple enterprises for a specific business opportunity. First we discuss both paradigms and then the Enterprise Architecture viewpoint of...

Enterprise Architecture (EA) projects require analyzing and designing across the whole enterprise and its environment. Enterprise architects, therefore, frequently develop enterprise models that span from the markets in which the organization operates down to the implementation of the IT systems that support its operations. In this paper, we present SEAM for EA: a method for defining an enterpr...

Unexpected events in hierarchical production planning, such as rush orders, labor problems, lack of availability of materials and faulty machines have to be managed efficiently because they represent a risk for business continuity, based on their impact and duration. The use of inter-enterprise architecture offers multiple benefits for collaborative networks, including: business strategy and in...

This paper presents the Integrated Enterprise Service Architecture (IESA). The IESA is a technical architecture that specifies an integrated modeling and execution platform that provides business operational support for modern enterprises structured as virtual organizations. The IESA specification serves as an architectural blueprint for how to develop integrated, interoperable and evolving ent...
