Enterprise architecture is a model-based approach to IT management used for promotion of good IT decision making. Thus, an enterprise architecture framework needs to support various forms of analysis. Creation of enterprise architecture models is costly and without intrinsic value, therefore it is desirable to create models that effectively support the sought after analysis. This paper presents...

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...

The Mobile Enterprise is a new form of enterprise in the contemporary mobile era. Although several well-known enterprise architecture frameworks are used by enterprises, it is apparent that there is no industry standard available to enable an enterprise to transform its business processes to incorporate mobile technologies to advantage. This paper presents a conceptual Mobile Enterprise Archite...

Although there are many existing and standard methods, such as RM-ODP and MDA, to develop a single distributed system to assure it consistent with the business requirements, the different enterprise-wide systems of one same enterprise might not be consistent with each other themselves because of the inconsistent business requirement model for each other. Enterprise model could describe the comm...

This article presents a novel method and development paradigm that proposes a general template for an enterprise information structure and allows for the automatic generation and modification of enterprise workflows. This dynamically integrated workflow development approach utilises a conceptual ontology of domain processes and tasks, enterprise charts, and enterprise entities. It also suggests...

Because of the pressure of competition and the rapidly changing business environment, organizational knowledge emerges as an important reusable resource. Knowledge management is based on the viewpoint that an organization can take proper steps to clear obstacles lying ahead and give good services to its customers by not only differentiating internal knowledge resources for competitive edges, bu...

Enterprise Architecture (EA) is employed by enterprises for providing integrated environment to support the alignment of enterprise’s business and Information Technology (IT). EA Implementation Methodology (EAIM) provides methods for managing, developing, and maintaining EA implementation. Several EAIMs have been proposed in literature; however effectiveness of EAIM has mostly been anecdotal, a...

The Model-driven Architecture (MDA) approach has been recognised as a methodology that can help enhance agility and speed in the implementation of enterprise IT systems. This article introduces the concept of MDA and how it helps in managing the complexities of integration and improving business-IT alignment. It highlights how DSTA uses various MDA techniques to achieve a process-oriented softw...

Abstract: Enterprise architecture (EA) frameworks are used to ensure interoperability of information systems and improve the effectiveness and efficiency of business organisations. Several methods have been proposed for selecting suitable frameworks. Although these methods are useful, none of them captures the uncertainties inherent in multi-attribute framework selection problems that embrace b...
