A Survey of Approaches to Virtual Enterprise Architecture: Modeling Languages, Reference Models, and Architecture Frameworks

As the theory and practice of enterprise architecture became mature, researchers and practitioners have started applying similar concepts and approaches to virtual enterprises. The virtual enterprise is a temporary coalition of enterprises joining hands to exploit a particular opportunity. Virtual Enterprise Architecture addresses a Virtual Enterprise holistically at a strategic level. This article provides a definition of Enterprise Architecture, Virtual Enterprise, and Virtual Enterprise Architecture and presents results from a study of six approaches to virtual enterprise architecture for virtual enterprises (NEML, CAML, AVERM, VERAM, BM VEARM, and ARCON). Interestingly, all of these approaches attempt to provide a holistic coverage of Virtual Enterprises, but have significant difference in the way they approach it. This article is aimed as an aid for researchers and practitioners to study different approaches for strategic planning of enterprise architecture.

Rational Systems Design for Health Information Systems in Low-income Countries: An Enterprise Architecture Approach

Low-income countries with their funding and implementing partners are increasingly recognizing health information systems (HIS) as an essential way to strengthen and support health systems. There is tremendous potential for innovations in information and communication technologies to assist health managers, health workers, and patients. Yet individual technologies and software applications are often developed without specifying how they will interact and communicate with existing and future information systems. Furthermore, they are developed without giving adequate attention to the needs the information system is supposed to address, resulting in software applications that do not effectively meet user needs. There is a lack of documented systematic methodology for gathering and documenting requirements for developing HIS. This article introduces a systematic, architected, and rational approach (SARA) for the design and development of health information systems. SARA, based on an Enterprise Architecture (EA) approach, represents a portfolio of practices, tools, and methods that can be easily and appropriately adapted and applied in the design phase of health information system development. This article will present early efforts to develop this portfolio including lessons learned from applying SARA in Tanzania.

An Enterprise Architecture for Banking

This article is about a practical application of an Enterprise Architecture (EA) framework, process, and methodology for developing an EA in the retail banking industry. The case shows the progression from the first EA plans and ideas, through the development of the EA capability for the bank, and finally the application of the framework to the development of the first iteration of the EA, focused on aligning customer service with the bank’s main strategic goals and drivers.

Arquitectura Empresarial en el Sector Bancario

El presente artículo se refiere a un caso de aplicación práctica del proceso, marco y metodología de Arquitectura Empresarial (AE) para la Banca Comercial en América Latina (Costa Rica).
