The Globemen Consortium has developed the virtual enterprise reference architecture and methodology (VERAM), based on GERAM and developed reference models for virtual enterprise management and joint mission delivery. The planned virtual enterprise capability includes the areas of sales and marketing, global engineering, and customer relationship management. The reference models are the basis fo...

Reference architectures are most commonly thought of as tools which enable modules developed at different institutions to be easily integrated. However, reference architectures can also be used for other purposes. In particular, they can make it easier to describe the architecture of systems, by allowing developers to just describe how their architecture differs from the reference one. This is ...

Reference architectures provide major guidelines for the structure of a class of information systems. Because of their fundamental role, reference architectures have to be of high quality. Before accepting a reference architecture, it has to go through a rigorous evaluation process. A number of methods exist for the evaluation of software architectures. In this paper, we analyze the main differ...

Cross-organizational electronic collaboration is about to gain significant momentum and facilitates the emergence of a globally networked information service economy. However, existing solutions for the realization of such business relationships still exhibit weaknesses with respect to both managerial and technological aspects. In this work, we propose a service-oriented reference architecture ...

For the past few years, the evolution of cloud computing has been potentially becoming one of the major advances in the history of computing. But is cloud computing the saviour of business? Does it signal the demise of the corporate IT functionality entirely? However, if cloud computing has to achieve its potential, there is a need to have a clear understanding of various issues involved, both ...

Many enterprises today struggle with the challenge of using the full potential of ICT for a rapid creation of global customer focused, efficient and effective virtual enterprises. This paper presents a Virtual Enterprise Reference Architecture (based on the draft international standard GERAM) to serve as a common integrating basis for these efforts, recognising the global challenge for common u...

The U.S. Department of Defense (DoD) requires common architectures that enable the collection, processing, analysis, seamless integration, dissemination, and reuse of information and technology in order to achieve its objectives of interoperability. We attempt to provide a high-level overview of some of the key DoD architectural standards and frameworks and illustrate how the NIST 4D/RCS relate...

Damit serviceorientierte Architekturen (SOAs) ihr Potential voll entfalten können, müssen neben technischen auch methodische und organisatorische Aspekte betrachtet werden. Enterprise Architecture Frameworks (EAFs) ermöglichen die dazu notwendige ganzheitliche Sicht auf das Unternehmen. Einzelne EAFs sind meist zu spezialisiert, um als Framework für die SOA angewendet werden zu können. Das Meta...

bstract: In the IMS-project Globeman21, the enterprise reference architecture GERAM was used as basis for creation of a virtual enterprise framework model. The model was used to map different industrial pilot projects, to classify virtual enterprise concepts, and as underlying structure for a virtual enterprise management methodology. The paper gives a survey of the use of GERAM and the results...
