THE IMPLEMENTATION OF REFERENCE MODEL Reference model must be maintained and modified for practical use. In order to shed some light on genuine EA best practices that work in organisations and provide a handy reference model of enterprise architecture, previously I developed Enterprise architecture on a page as a convenient one-page view of popular EA artifacts that proved useful with their essential properties, e.g. The architecture classification is well defined with a code, a name and description to avoid miss communication. The model can be used to define architecture for any specific scenario applicable for an enterprise utilizing Solution Building Blocks (SBBs) implemented by any new or existing participants of an enterprise Cloud Ecosystem. Both the United States government and the British government have invested on architecture classification. However, ITIL and Cobit from British government have become popular in many countries and gaming support in the international EA community. Why Architecture Classification? Resources > Dragon1 Framework for Enterprise Architecture, Enterprise Architecture Models > Enterprise Performance Framework, Reference Models > Enterprise Architecture Core Reference Model. Then based on these questions, you can develop an approach and identify the models that you need. However, it has become fashionable in certain circles to apply the term in a wider, more general sense, where it may refer to a classification of things or concepts, as well as to the principles underlying such a classification.

The U.S OMB, leverage on it governing power, has dedicated significant effort to establish the consolidate reference models within the federal government agencies. EA community to overcome the challenge of stovepipe system have adopt the reference model concept from the network communication practice. This article discuss architecture classification from the aspect of : . Recently, the Banking Industry Architecture Network (BIAN) published version 8.0 of its financial industry reference architecture. It also provides a common vocabulary with which to discuss implementations, often with the aim to stress commonality. The Common Approach to Federal Enterprise Architecture also defines a Consolidated Reference Model.This framework establishes a common language to describe and analyze investments. Reference Models are introduced by EA as the reference to find the reusable resources. We encourage you to read our updated PRIVACY POLICY and COOKIE POLICY. The Technical Reference Model ... -specific Technology Architecture is to look beyond the set of real-world platforms already in existence in the enterprise. 2.2 EA classification for Service Level agreement. they are not implemented directly. The most popular reference model is the Open System Interconnection(OSI) Reference Model. At the top of this structure is a single classification, the root node, that applies to all objects. Taxonomy is a fundamental training for biologist to classify organism so does Reference model is the fundamental training for Enterprise Architect 3. As Enterprise Architecture have evolved for IT centric to business oriented approach, the US government have extend reference model to performance, business, services, data and technology with PRM, BRM, SRM, DRM and TRM. Since 1999, the DoD hasn’t used the TAFIM, and it’s been eliminated from all process documentation. 4.5 Architecture classification for Service Level Agreement(SLA) Information age has evolved toward service oriented architecture, cloud computing and out sourcing.

The business capability model describes the capabilities that exist within the organisation to deliver the organisations value proposition. The framework is made up of six reference models that can be used with some latitude to apply to private sectors: 1. People come to TRM to look for the technology standard rather the architecture classification. Taxonomy is the practice and science of classification. Originality, Enterprise Architects classify their enterprise architecture for the purpose of architecture communication to reuse, share and learning the right experiences from each other. ... Standards and Reference Models that constitute the architecture framework and the compliance of projects as documented in the project Architecture Compliance Form (ACF). Central to the Reference Architecture are the EA purposes. Built, and continually evolving, based on our experience as enterprise architecture consultants to many of the world's top organisations, Essential has been built for architects, by practising architects, with a meta model and views geared towards delivering stakeholder value and answering the key enterprise architecture questions. As demonstrated within the example, additional information can be incorporated into the model to communicate the status of the asset lifecycles, asset licencing arrangements, asset support models, and/or indicate whether an asset is a global or local standard. Create your account to get started. It was released as a reference model for enterprise architecture, offering insight into DoD’s own technical infrastructure, including how it’s structured, maintained and configured to align with specific requirements. They cover business, service, components, technical, and data. From Wikipedia, a reference model is a model in systems, enterprise, and software engineering is an abstract framework or domain-specific ontology consisting of an interlinked set of clearly defined concepts produced by an expert or This Foundation Architecture is embodied within the Technical Reference Model (TRM), which provides a model and taxonomy of generic platform services. The use of reference model. They define the infrastructure as well as the skills and procedures needed for the implementation of the respective system [Nie08]. Business Architecture. SaaS platform for Enterprise Architecture. It is another key anchor for your enterprise architecture and provides the basis to understand: Where you have duplication; Where you have risk; How you can reduce costs; How you can increase agility THE USE OF REFERENCE MODEL 4.1 Use reference model to classify and synchronize enterprise architecture with industry Enterprise Architects classify and synchronize their enterprise architecture with industry for the purpose of learning experiences from the right category and resource. Federal Reference Models The Federal Enterprise Architecture Framework (FEAF) was established in 1999 by the Chief Information Officers (CIO) in response to the Clinger-Cohen Act of 1996. To write a Service Level Agreement, both parties need clear definition on performance, business, service, data and technology. It consists of a set of interrelated reference modelsdesigned to facilitate cross-agency analysis and the identification of duplicative investments, gaps and opportunities for collaboration within and across agencies. The best way to make transition from stovepipe culture to EA culture is EA education, it is difficult to teach old dog new trick due the burden of existing resistance. The TOGAF Foundation Architecture is an architecture of generic services and functions that provides a foundation on which more specific architectures and architectural components can be built. The FEA has five reference models. This reference architecture is composed of a long list of application components and services necessary to enable the services defined in the TRM.
