Since 1999, the DoD hasn’t used the TAFIM, and it’s been eliminated from all process documentation. The architecture classification is well defined with a code, a name and description to avoid miss communication. Reference model is the corner stone for EA to line up rather than an architecture best practice. The Application Reference Model (ARM) supports architectural analysis and reporting in the applications sub-architecture view of the overall EA. United states is not the only country making effort in Enterprise Architecture classification. Under this law, federal agencies has established many technical reference models as show on figure. Again, this reference architecture fosters a common vocabulary [Kel11]. An Enterprise Architect must know all the Enterprise Architecture classification so that they can classify their architecture as a common language to communicate with each other. The reference model become critical to specify service catalog and service agreement as shown in the ITIL Version 3. The notion of Reference model for architecture assessment have dim the value of architecture classification in the EA global EA community. The DRM is a framework whose primary purpose is to enable information sharing and reuse across the federal government via the standard description and discovery of common data and the promotion of uniform data management practices. 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. Myth #2: Reference model have no value to architects, it is only for architecture assessment Some EA experts claim that reference model is only create by US OMB for the purpose of architecture assessment and it have no architecture value for a real architects. You can re-use this reference model to make it part of your enterprise meta model on Dragon1. 6. 5. 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. 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. The following figure illustrate the background of reference model. Taxonomy is a fundamental training for biologist to classify organism so does Reference model is the fundamental training for Enterprise Architect 3. Architecture classification to speak the language become essential for preparing Device Level Agreement between the parties of SOA, Cloud computing and Out sourcing. Originality, Enterprise Architects classify their enterprise architecture for the purpose of architecture communication to reuse, share and learning the right experiences from each other. Performance Reference Model The Performance Reference Model (PRM) supports architectural analysis and reporting in the strategy sub-architecture view of the overall EA. Then based on these questions, you can develop an approach and identify the models that you need. This Foundation Architecture has two main elements: The Technical Reference Model (TRM), which provides a model and taxonomy of generic platform services Although the US government have established the Federal Enterprise Architecture Consolidate Reference Model for a decade, it have not become a popular knowledge except in the US Federal Enterprise Architecture community. As the notional reference model figure below illustrates, reference models capture the elements of the architectural views, and translate those elements into text. 2. The framework is made up of six reference models that can be used with some latitude to apply to private sectors: 1. 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. 3.6 AGA Reference Models agency context diagram 16 four Using the Australian Government Architecture Reference Models 18 4.1 Applying the AGA Reference Models to EA 18 4.2 AGA Reference Models and catalogues 22 4.3 AGA Reference Models and the AGA Investment Templates 22 five Using the AGA Metamodel 24 5.1 Why the AGA Metamodel is needed 24 By using our site, you acknowledge that you have read and understand our Cookie Policy, Privacy Policy, and our Terms of Service.

The Profile is part of the Unified Modeling Language extension mechanism allowing a modeler to make extensions to the grammar of the language by using Stereotypes and Tagged Valuesto create domain, industry or organizational level elements. A reference 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 body of experts to encourage clear communication. The Technology Reference Model provides an understanding of the technologies that are required to support the application estate. May 8, 2017 - Enterprise Architecture Reference Model is a Dragon1 reference model for EA. This provides a comprehensive model of the business capabilities, business scenarios, service domains and business objects used in banking and other financial services. 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. ... Standards and Reference Models that constitute the architecture framework and the compliance of projects as documented in the project Architecture Compliance Form (ACF). The second reference architecture is the Integrated Information Infrastructure Reference Model (III-RM) [11b]. It provide detail classification of the Performance Reference Model (PRM), The Business Reference Model (BRM), The Service Reference Model(SRM) and the Technology Service model(TRM). Enterprise architecture practice on a page can be helpful in many ways to various people involved in EA-related activities: It offers an evidence-based reference model of an EA practice to organisations starting their EA journeys; It provides a convenient framework for thinking about an EA practice to architects and architecture managers 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. WHAT IS EA REFERENCE ARCHITECTURE Enterprise Architecture Classification are used to facilitate the exchange of reusable knowledge by using the same terminology and in the same context to assure the accuracy of communication to exchange the reusable knowledge. All these layers and entities are part of a container entity like 'Enterprise', 'Organization' or Company. And of course you can alter the reference model to your own theory about enterprise strategy. The U.S OMB, leverage on it governing power, has dedicated significant effort to establish the consolidate reference models within the federal government agencies. 3.3 The Structure of Reference Model Reference model as taxonomy is in a hierarchical structure. 4.3 Use reference model to write technical reference manual Many organization have made significant investment to develop Technical Reference manual as the Enterprise Architecture handbook. 7.5.2 Developing the Baseline Description. They are not solution architectures, i.e. Even with a reference model, the challenges can be substantial. Myth #4, Technical Reference Model as standard profile TRM is the classification and category of IT standards, it is not the standard catalog. Recently, the Banking Industry Architecture Network (BIAN) published version 8.0 of its financial industry reference architecture. People come to TRM to look for the technology standard rather the architecture classification. 2.1 To learn the right experience from each other. It is crucial to establish an international Enterprise Architecture classification based on the science of Taxonomy. 2.3 EA classification to see the big picture of EA. Application Portfolio Management: how to create effective application landscapes? He have served as Enterprise Architect for US Federal government space with many years of hands on EA experiences. The US FEAPMO Consolidate Reference model has been a very visionary EA classification effort tie the different reference model together. 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 Data Architecture Reference Model 1.0 Introduction First things first: what is a reference model? 4.5 Architecture classification for Service Level Agreement(SLA) Information age has evolved toward service oriented architecture, cloud computing and out sourcing. It is essential to include the discipline of architecture classification discipline as the fundamental of Enterprise Architecture similar to taxonomy classes in many other scientific programs. If an enterprise has existing Architecture Descriptions, … of Civil engineering form Howard University in 1979 and M.S. A reference architecture in the field of software architecture or enterprise architecture provides a template solution for an architecture for a particular domain. We'll send an email with a link to reset your password. Reference model enable Service Level Agreement(SLA) as the the information age culture evolved to out sourcing, service oriented architecture and clouding computing. 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. Both the United States government and the British government have invested on architecture classification. It … Reference model enable reuse, sharing and learning experience from each other to overcome the challenge of stovepipe system. The consolidation reference further demonstrate that reference model is all about Enterprise Architecture classification and have nothing to do with architecture approach. As the notional reference model figure below illustrates, reference models capture the elements of the architectural views, and translate those elements into text. WHY REFERENCE MODEL? Within Enterprise Architect, this graphic also serves as a mechanism for navigating through the model. 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 purpose of the FEAF is to facilitate shared development of common processes and information among Federal Agencies and other government agencies. http://www.slideshare.net/wuchizong. The surface area across which an organization must integrate has expanded dramatically in recent years. This was a five-layer reference model that illustrates the interrelationship of business, information system, and technology domains. EAM Reference Model & Reference Architecture Foundations Reference models and reference architectures are abstract solution patterns for the design of systems in a specific domain [16]. Enterprise Architecture, Government EA, Reference Models FEA Reference Models include the Consolidated Reference Model Version 2.3 and Data Reference Model 2.0. Maracanã, 229 – Rio de Janeiro Goran D. Putnik, D.Sc. Why Architecture Classification? A reference architecture is a reference model mapped onto software elements (that cooperatively implement the functionality defined in the reference model) and the data flows between them. 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. EA industry have used Technical Reference Model to classify their technical standards. Federal Enterprise Architecture Framework (FEAF) – which is a reference model that was introduced in 1996 for IT effectiveness. 3.1 The science of EA taxonomy Reference Model serve as the taxonomy of Enterprise Architecture. And of course you can alter the reference model to your own theory about enterprise strategy. Dragon1 as open EA Method defines a reference model for enterprise architecture. This may be true for stovepipe architects, reference model is fundamental for Enterprise architects to share, reuse and learn experiences of each other. Myth #1, Developing reference Model EA professional are asked to develop reference model where the reference models are considered as an architecture best practice. It can become an important part to agile software delivery. The use of reference model. To develop a useful enterprise architecture (EA) it is important to first understand the questions you want to answer with your architecture. 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. Dragon1, SaaS platform for Enterprise Architecture.The #1 EA Tool, DEMO: Generate an interactive Process Application Map using your own data. Initially, the reference model begins from the Technical Reference model to focus on technology at The 1996 Clinger-Cohen Act (CCA), formerly the Information Technology Management Reform Act of 1996(ITMRA). These topics provide starting-point guidance for enterprise resource planning. Newsletters may contain advertising. 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. . The Data Reference Model (DRM) is one of the five reference models of the Federal Enterprise Architecture (FEA). Performance reference model: links business-partner strategy, internal business components, and investments to measure the impact of those investments on strategic outcomes 2. Business refere… A Reference Architecture is an anchor for other architecture deliverables; the Business Capability model discussed in Part 1 is an example. 3.2 The Scope of Enterprise Architecture Reference Model The scope of Enterprise Architecture Classification is not only about Information Technology. Below is a 2d flat version of a simple Enterprise Architecture Meta model of an Organization with 2 business units. An architecture framework provides the tools and approaches necessary to abstract this information to a level of detail that is manageable. Integration must now treat cloud as a first-class citizen and cater to radically different requirements from a broader range of users. 4.4 Use reference model for architecture assessment Governance organization use reference models for the purpose of Enterprise Architecture assessment. By signing up you agree to our Terms of Use and Privacy Policy. However, reference model are used to classify an organizations architecture category rather than serve as an architecture best practice. This series of topics illustrates several architecture approaches for mergers, acquisitions, divestitures, and other scenarios that might lead you to migrate to a new cloud tenant. This is very misleading. OMB developed a set of reference models, practice guidance, and an enterprise architecture assessment framework under its Federal Enterprise Architecture program. Resources > Dragon1 Framework for Enterprise Architecture, Enterprise Architecture Models > Enterprise Performance Framework, Reference Models > Enterprise Architecture Core Reference Model. Reference models provide textual extractions of underlying architectural data. THE BACKGROUND Reference Models are not strangers to the network communication engineers, they have talk to each other in on the same page with the same protocol. EA community have used Technical Reference Model to classify and categorize their technology standards from the beginning of EA. 7.1 The maturity of Reference Model Although the US Federal Enterprise Architecture Program Management Office(FEAPMO) have invested significant effort on the consolidate reference model, it only serve as the foundation for Enterprise Architecture Classification. Your email address will not be published. In enterprise engineering a business reference model is part of an Enterprise Architecture Framework or Architecture Framework. To keep the reference model simple, the group of reference model is consolidated to become the consolidate reference model. The Myth of reference model. Architecture Development Reference Models. Rather, they are used as a constraint for more concrete architectures. 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. Join a community of over 1M of your peers. What is Reference Model?
