Effective management of such complexity and scale requires tools and approaches that architects can use. And of course you can alter the reference model to your own theory about enterprise strategy. 2.3 EA classification to see the big picture of EA. You can re-use this reference model to make it part of your enterprise meta model on Dragon1. For more detail on the please link to the FEAPMO reference model. Reference model enable Service Level Agreement(SLA) as the the information age culture evolved to out sourcing, service oriented architecture and clouding computing. There are two essential parts to the Technical Reference Model: the packages, providing a model and taxonomy of generic platform services, and a graphic of nested services that facilitates visualization. Here are the reason for why reference model. You can re-use this reference model to make it part of your enterprise meta model on Dragon1. Reference Model In module one of the MOOC, we introduced you to a Business Capability Model which can be used to provide business context and anchor a number of architecture views. Reference model enable EA communication, It is the corner stone of Enterprise Architecture. Recently, the Banking Industry Architecture Network (BIAN) published version 8.0 of its financial industry reference architecture. Reference Models are introduced by EA as the reference to find the reusable resources. 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. 3.2 The Scope of Enterprise Architecture Reference Model The scope of Enterprise Architecture Classification is not only about Information Technology. 2.2 EA classification for Service Level agreement. A framework helps bring enterprise design tasks into focus and produces … Architecture Development Reference Models. 7.5.2 Developing the Baseline Description. Below you see the most recent version of the Dragon1 Enterprise Architecture Reference model. IT Services / Enterprise Architecture Framework.docx / PUBLISHED / v 3.0 Page 4 of 34 1 Introduction 1.1 Background Often compared with town-planning or urban design, Enterprise Architecture (EA) is a holistic approach to managing the complexity of IT from a business perspective. 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. Introduction 1.1 Purpose. Join a community of over 1M of your peers. 1. C.2.3.1 Align to the GC Business Capability model C.2.3.1.1 Define program services as business capabilities to establish a common vocabulary between business, development, and operation; C.2.3.1.2 Identify capabilities that are common to the GC enterprise … In this environment, the customers and service providers establish service agreement from the aspect of performance requirement, line of business, service category and technology. TOGAF is based on TAFIM (Technical Architecture Framework for Information Management), an IT management framework developed by the U.S. Defense Department in the 1990s. Even with a reference model, the challenges can be substantial. Reference models are used in the engineering of use for communicate standards in an organized approach Reference model was introduced by the evolution of EA as the reference to find reusable resource Definition Reference Model serve as the architecture taxonomy to establish the common architecture communication platform and keep architect on the same page and mitigate the risk of learning from the wrong experience. are described as “standardized architectures that provide a frame of reference for a particular domain The model should be created as part of the set up of the architecture programs but will typically require extending as technology standards are introduced and retired. . However, the introduction of reference model is not a easy transition for the stovepipe oriented application development community because there no need to communicate with each other in the stovepipe culture. 3.2 The Scope of Enterprise Architecture Reference Model The scope of Enterprise Architecture Classification is not only about Information Technology. 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 Reference model enable enterprise architecture to learn from the right resources. A Reference Architecture is an anchor for other architecture deliverables; the Business Capability model discussed in Part 1 is an example. The associated meta-model will illustrate the relationship between the reference models, with the use cases providing examples of how each reference model can be applied. These topics provide starting-point guidance for enterprise resource planning. The Technology Reference Model provides an understanding of the technologies that are required to support the application estate. As the notional reference model figure below illustrates, reference models capture the elements of the architectural views, and translate those elements into text. A reference models are used for architecture classification to enable communication rather than for architecture compliance. It also can be used to establish service level agreement and Enterprise architecture mark up language. 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. These elements can also have Tagged Values added to capture additional properties. The consolidation reference further demonstrate that reference model is all about Enterprise Architecture classification and have nothing to do with architecture approach. http://www.slideshare.net/wuchizong. example: The US OMB have use their consolidate reference model for the purpose of Enterprise Assessment. 3.1 The science of EA taxonomy Reference Model serve as the taxonomy of Enterprise Architecture. 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. BM_Virtual Enterprise Architecture Reference Model for Concurrent Engineering: An experiment Antonio José Caulliraux Pithon, PhD Departamento de Engenharia de Produção, Centro Federal de Educação Tecnológica do Rio de Janeiro – CEFET/RJ Av. However, ITIL and Cobit from British government have become popular in many countries and gaming support in the international EA community. John has earned the M.S. 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. The external reference architecture sources that have been used by other countries such as USA, Europe and Australia are used as reference to derive this MyGovEA Reference Model as follows: 1.) The US FEA consolidate reference model is a good start for this purpose. This is very misleading. The Performance Reference Model(PRM) classify business performance, Business Reference Model(BRM) classify line of business, Service Reference Model(SRM) classify the category of business services and the Technical Reference Model classify the Technology. Agile enterprise architecture -- which focuses an organization around a flexible, extended collection of structures and processes that can grow. Dragon1 as open EA Method defines a reference model for enterprise architecture. This mechanism can be used to create a Technical Reference Model by creating the foundational elements,, services, interfaces and connectors as stereotypes within the profile. 7.3 The education of Reference Model Many academic institution have initiated Enterprise Architecture education program. This reference architecture implements an extract, load, and transform (ELT) pipeline that moves data from an on-premises SQL Server database into Azure Synapse and transforms the data for analysis.. A reference implementation for this architecture is available on GitHub.. To keep the reference model simple, the group of reference model is consolidated to become the consolidate reference model. Since 1999, the DoD hasn’t used the TAFIM, and it’s been eliminated from all process documentation. The Enterprise Architect use reference model to classify their architecture rather then developing their own reference model. Reference model enable reuse, sharing and learning experience from each other to overcome the challenge of stovepipe system. FY10 FEA Reference Model Mapping Quick Guide. The Technical Reference Model ensures that architectures are created consistently and repeatedly based on a standard set of elements. THE MYTH OF REFERENCE MODEL For the stovepipe oriented application development community, the introduction of “reference model” have contributed significant confusion because there is no need to communicate between stovepipe systems. Reference models provide textual extractions of underlying architectural data. The application developers are expecting to see architecture best practice in EA rather than EA classification. Your email address will not be published. Federal Enterprise Architecture Framework (FEAF) – which is a reference model that was introduced in 1996 for IT effectiveness. For example: reference model tree in the US FEA Consolidate Reference Model. A reference model establish the common Enterprise Architecture language and classification for EA community to talk in the same language and communication on the same page. The principles apply to all IT projects and architecture-related work. 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 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. 3.3 The Structure of Reference Model Reference model as taxonomy is in a hierarchical structure. informational contents, presentation formats, typical use cases, lifecycles and purposes (see Enterprise architecture on a single page). they are not implemented directly. "John Chizong Wu has actively participated and advocate practical Enterprise Architecture approach in the Washington DC area since 1998. EA industry have used Technical Reference Model to classify their technical standards. A reference architecture in the field of software architecture or enterprise architecture provides a template solution for an architecture for a particular domain. Myth #4, Technical Reference Model as standard profile TRM is the classification and category of IT standards, it is not the standard catalog. People come to TRM to look for the technology standard rather the architecture classification. 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. Integration must now treat cloud as a first-class citizen and cater to radically different requirements from a broader range of users. Architecture approaches for Microsoft cloud tenant-to-tenant migrations. Originality, Enterprise Architects classify their enterprise architecture for the purpose of architecture communication to reuse, share and learning the right experiences from each other. The second reference architecture is the Integrated Information Infrastructure Reference Model (III-RM) [11b]. 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. The business capability model describes the capabilities that exist within the organisation to deliver the organisations value proposition.

The term of TRM has become the synonymy of standard profile. WHY REFERENCE MODEL? Scenario: An organization has a large OLTP data set stored in a SQL Server database on premises. It is critical to have a common reference model to facilitate the communication handshake. EA documents the structural and behavioural building blocks that The most popular reference model is the Open System Interconnection(OSI) Reference Model. The most difficult thing in EA is to get Enterprise Architects to talk in the same language. Below you see the most recent version of the Dragon1 Enterprise Architecture Reference model. Reference models are used in the engineering of use for communicate standards in an organized approach Reference model was introduced by the evolution of EA as the reference to find reusable resource Definition Reference Model serve as the architecture taxonomy to establish the common architecture communication platform and keep architect on the same page and mitigate the risk of … It is crucial to establish an international Enterprise Architecture classification based on the science of Taxonomy. The reference model become critical to specify service catalog and service agreement as shown in the ITIL Version 3. Taxonomy is a fundamental training for biologist to classify organism so does Reference model is the fundamental training for Enterprise Architect 3. Download the EA Capability Reference Documents Based upon the organizations preferences current & target execution is assessed to provide priority for improvement. Before EA, organization compose a list of standard in alphabetic order without architecture context. The challenge of reference model .

It can become an important part to agile software delivery. 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. 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]. 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. 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. 4.2 Use reference model to render architecture standards This is the most popular utilization of reference model. 5. . Why Architecture Classification? The segment model at its core allows a distinction of … Nodes below this root are more specific classifications that apply to subsets of the total set of classified objects. However, reference model are used to classify an organizations architecture category rather than serve as an architecture best practice. Reference model is the corner stone for EA to line up rather than an architecture best practice. 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. It can become an important part to agile software delivery. The notion of Reference model for architecture assessment have dim the value of architecture classification in the EA global EA community. EA community have used Technical Reference Model to classify and categorize their technology standards from the beginning of EA. Enterprise Architecture, Government EA, Reference Models FEA Reference Models include the Consolidated Reference Model Version 2.3 and Data Reference Model 2.0. Under this law, federal agencies has established many technical reference models as show on figure. 2. This was a five-layer reference model that illustrates the interrelationship of business, information system, and technology domains. 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 architecture classification is well defined with a code, a name and description to avoid miss communication. 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. Maracanã, 229 – Rio de Janeiro Goran D. Putnik, D.Sc. Agile enterprise architecture -- which focuses an organization around a flexible, extended collection of structures and processes that can grow.
