Effective management of such complexity and scale requires tools and approaches that architects can use. United states is not the only country making effort in Enterprise Architecture classification. 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. As the notional reference model figure below illustrates, reference models capture the elements of the architectural views, and translate those elements into text. OMB developed a set of reference models, practice guidance, and an enterprise architecture assessment framework under its Federal Enterprise Architecture program. Save my name, email, and website in this browser for the next time I comment. The Consolidated Reference Model of the Federal Enterprise Architecture Framework (FEAF) equips OMB and Federal agencies with a common language and framework to describe and analyze investments. 3.2 The Scope of Enterprise Architecture Reference Model The scope of Enterprise Architecture Classification is not only about Information Technology. Myth #3, Reference model as the best practice Some EA office use reference model as the best practice architecture model and require agency compliance. Originally taxonomy referred only to the classifying of organisms (now sometimes known as alpha taxonomy) or a particular classification of organisms. . It is an Enterprise Architecture classification effort to support EA communication on the same page. The notion of Reference model for architecture assessment have dim the value of architecture classification in the EA global EA community. 3.2 The Scope of Enterprise Architecture Reference Model The scope of Enterprise Architecture Classification is not only about Information Technology. Performance Reference Model The Performance Reference Model (PRM) supports architectural analysis and reporting in the strategy sub-architecture view of the overall EA. Under this law, federal agencies has established many technical reference models as show on figure. The Technical Reference Model ensures that architectures are created consistently and repeatedly based on a standard set of elements. The Technical Reference Model ... -specific Technology Architecture is to look beyond the set of real-world platforms already in existence in the enterprise. Enterprise Architects must be familiar with reference model for architecture classification. A reference architecture in the field of software architecture or enterprise architecture provides a template solution for an architecture for a particular domain. 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. Since 1999, the DoD hasn’t used the TAFIM, and it’s been eliminated from all process documentation. 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. In the mean time, he have contributed significant efforts in EA evangelism to participate the government enterprise architecture working groups; serve as the president of the Association of Enterprise Architect DC chapter which support grass root EA seminars for many years; contribute author of Cutter Consortium Enterprise Architecture Advisory Service; and hosting the Light Enterprise Architecture website www.liteea.com; and presenting practical concepts in SlideShare. 7.3 The education of Reference Model Many academic institution have initiated Enterprise Architecture education program. Reference models or architectures provide a common vocabulary, reusable designs and industry best practices. in Computer Science from Florida Institute of Technology in 1984. Taxonomy is a fundamental training for biologist to classify organism so does Reference model is the fundamental training for Enterprise Architect 3. Below you see the most recent version of the Dragon1 Enterprise Architecture Reference model. Federal Enterprise Architecture Framework (FEAF) – which is a reference model that was introduced in 1996 for IT effectiveness. Reference model enable enterprise architecture to learn from the right resources. An Enterprise Architecture Framework defines in a series of reference models, how to organize the structure and views associated with an Enterprise Architecture. 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. informational contents, presentation formats, typical use cases, lifecycles and purposes (see Enterprise architecture on a single page). This Foundation Architecture is embodied within the Technical Reference Model (TRM), which provides a model and taxonomy of generic platform services. 6. At the top of this structure is a single classification, the root node, that applies to all objects. This reference architecture is composed of a long list of application components and services necessary to enable the services defined in the TRM. 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 The following figure illustrate the background of reference model. The inter discipline and professional experience in engineering and computer science is a great advantage in developing EA concept. "John Chizong Wu has actively participated and advocate practical Enterprise Architecture approach in the Washington DC area since 1998. These five points combine with a segment model to create a perspective on how best to install enterprise architecture. It also can be used to establish service level agreement and Enterprise architecture mark up language. Newsletters may contain advertising. 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. A reference models are used for architecture classification to enable communication rather than for architecture compliance. None of these materials devotes much attention to information security management or risk management, although the reference models acknowledge risk management and mitigation as agency management functions [32] . 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. To keep the reference model simple, the group of reference model is consolidated to become the consolidate reference model. Agile enterprise architecture -- which focuses an organization around a flexible, extended collection of structures and processes that can grow. This Foundation Architecture has two main elements: The Technical Reference Model (TRM), which provides a model and taxonomy of generic platform services 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]. 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. 2.1 To learn the right experience from each other. ", © 1995-2020 Toolbox is among the trademarks of, Reference model – The Enterprise Architecture Classification, 7 WFH Perks IT Professionals Want in 2021, Moving Beyond Linear Customer Journeys in 2021, 4 Winning IT Strategies to Survive Future Crises, What Your Disaster Recovery Strategy Should Look Like in 2021 – Part I, Digital Concierge Is Paving the Way for Contactless Experiences. 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. The Enterprise Architecture Capability Reference model is represented by a simple graphic and a complete textual description. Agile enterprise architecture -- which focuses an organization around a flexible, extended collection of structures and processes that can grow. The EA community have to work together to achieve a mature Enterprise Architecture classification. It is far from a mature Enterprise Architecture classification. 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. 2.3 EA classification to see the big picture of EA. As information evolved to cloud computing, service orient architecture and outsourcing, it is establish common language in Service Level Agreement from the aspect of performance, business, service, data and technology. The Application Reference Model (ARM) supports architectural analysis and reporting in the applications sub-architecture view of the overall EA. To develop a useful enterprise architecture (EA) it is important to first understand the questions you want to answer with your architecture. Business Architecture. are described as “standardized architectures that provide a frame of reference for a particular domain Reference model is perceived reference model as an architecture approach rather than an architecture classification. The Data Reference Model (DRM) is one of the five reference models of the Federal Enterprise Architecture (FEA). Initially, ITIL only address IT management and gradually evolved to all services in ITIL V3. In enterprise engineering a business reference model is part of an Enterprise Architecture Framework or Architecture Framework. The model provides a taxonomy for classifying the technology assets. 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 It can become an important part to agile software delivery. The Technology Reference Model provides an understanding of the technologies that are required to support the application estate. The Cloud Ecosystem Reference Model should be considered as an extension of an Enterprise Architecture Model. The US government establish the Federal Consolidate Reference Model and the British government establish ITIL and Cobit. Architecture Development Reference Models. It is important to establish international Enterprise Architecture classification so the all the Enterprise Architects can speak the same EA language. Federal Enterprise Architecture Framework (FEAF) – which is a reference model that was introduced in 1996 for IT effectiveness. The OMB reference model has not become popular as expected due to lack of continuous maintenance. 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. It can become an important part to agile software delivery. 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. And of course you can alter the reference model to your own theory about enterprise strategy. These topics provide starting-point guidance for enterprise resource planning. 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. Taxonomy is the practice and science of classification. 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. 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 … Collectively, the reference models comprise a framework for describing important elements o… Before EA, organization compose a list of standard in alphabetic order without architecture context. The British government have also invested on ITIL and Cobit to establish a common IT management classification 7.2 The authority of Reference Model Reference Model as the common EA communication language must establish the authority to serve as the global Enterprise Architecture classification. Reference model enable EA communication, It is the corner stone of Enterprise Architecture. 7.5.2 Developing the Baseline Description. The Common Approach to Federal Enterprise Architecture also defines a Consolidated Reference Model.This framework establishes a common language to describe and analyze investments. This article considers the primary drivers of change and the integration reference architecture that is evolving to meet the new demands. It … Enterprise Architecture, Government EA, Reference Models FEA Reference Models include the Consolidated Reference Model Version 2.3 and Data Reference Model 2.0. The surface area across which an organization must integrate has expanded dramatically in recent years. TOGAF – The Open Group Enterprise Architecture Framework: it provides an approach It is part of EA discipline. Join a community of over 1M of your peers. However, reference model are used to classify an organizations architecture category rather than serve as an architecture best practice. This may be true for stovepipe architects, reference model is fundamental for Enterprise architects to share, reuse and learn experiences of each other. The US FEA consolidate reference model is a good start for this purpose. And of course you can alter the reference model to your own theory about enterprise strategy. The Data Centre Services (DCS) Reference Architecture Document (RAD) has been developed to describe the reference architecture models for a common, shared and consolidated DC environment for the Government of Canada (GC) as an enterprise. 4.5 Architecture classification for Service Level Agreement(SLA) Information age has evolved toward service oriented architecture, cloud computing and out sourcing. Article byThe UX Blog We encourage you to read our updated PRIVACY POLICY and COOKIE POLICY. Myth #1, Developing reference Model EA professional are asked to develop reference model where the reference models are considered as an architecture best practice. By using our site, you acknowledge that you have read and understand our Cookie Policy, Privacy Policy, and our Terms of Service. 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). 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. 3.1 The science of EA taxonomy Reference Model serve as the taxonomy of Enterprise Architecture. Dragon1, SaaS platform for Enterprise Architecture.The #1 EA Tool, DEMO: Generate an interactive Process Application Map using your own data. Reference Models are introduced by EA as the reference to find the reusable resources. . Create your account to get started. The challenge of reference model . What is Reference Model? Integration must now treat cloud as a first-class citizen and cater to radically different requirements from a broader range of users. The reference model become critical to specify service catalog and service agreement as shown in the ITIL Version 3. 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. In module two we introduced you to a Technology Reference Model. They cover business, service, components, technical, and data. 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.. example: The US OMB have use their consolidate reference model for the purpose of Enterprise Assessment. 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. 2.2 EA classification for Service Level agreement. Download the EA Capability Reference Documents Based upon the organizations preferences current & target execution is assessed to provide priority for improvement. However, ITIL and Cobit from British government have become popular in many countries and gaming support in the international EA community. Originality, Enterprise Architects classify their enterprise architecture for the purpose of architecture communication to reuse, share and learning the right experiences from each other. 2.3 Architectural Patterns, Reference Models, and Reference Architectures. For example: reference model tree in the US FEA Consolidate Reference Model. 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. The most popular reference model is the Open System Interconnection(OSI) Reference Model. It is crucial to establish an international Enterprise Architecture classification based on the science of Taxonomy. 1. As a result, there are several common myth in reference model concept. 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. FY10 FEA Reference Model Mapping Quick Guide. In this article, I will introduce another helpful deliverable called Enterpris… Enterprise Architecture Reference Model - Dragon1 Enterprise Architecture Reference Model is a Dragon1 reference model for EA. Central to the Reference Architecture are the EA purposes. The risk of learning experience of each other is learning from the wrong experience by comparing apple to orange. To write a Service Level Agreement, both parties need clear definition on performance, business, service, data and technology. Enterprise Architecture Capability Reference Model The Enterprise Architecture Capability Reference model is represented by a simple graphic and a complete textual description. Introduction 1.1 Purpose. Reference models provide textual extractions of underlying architectural data. The Architect… If an enterprise has existing Architecture Descriptions, … He have served as Enterprise Architect for US Federal government space with many years of hands on EA experiences. THE IMPLEMENTATION OF REFERENCE MODEL Reference model must be maintained and modified for practical use. Reference models provide textual extractions of underlying architectural data.

Business refere… Resources > Dragon1 Framework for Enterprise Architecture, Enterprise Architecture Models > Enterprise Performance Framework, Reference Models > Enterprise Architecture Core Reference Model. 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 purpose of the FEAF is to facilitate shared development of common processes and information among Federal Agencies and other government agencies. Maracanã, 229 – Rio de Janeiro Goran D. Putnik, D.Sc. They define the infrastructure as well as the skills and procedures needed for the implementation of the respective system [Nie08]. 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. EA documents the structural and behavioural building blocks that 7. You can re-use this reference model to make it part of your enterprise meta model on Dragon1. Architecture approaches for Microsoft cloud tenant-to-tenant migrations. http://www.slideshare.net/wuchizong. 5. Required fields are marked *, You may use these HTML tags and attributes:
. The framework is made up of six reference models that can be used with some latitude to apply to private sectors: 1. It is critical to have a common reference model to facilitate the communication handshake. 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. Below you see the most recent version of the Dragon1 Enterprise Architecture Reference model. Architecture classification to speak the language become essential for preparing Device Level Agreement between the parties of SOA, Cloud computing and Out sourcing. Architecture Development Reference Models. This provides a comprehensive model of the business capabilities, business scenarios, service domains and business objects used in banking and other financial services. The consolidation reference further demonstrate that reference model is all about Enterprise Architecture classification and have nothing to do with architecture approach. A framework helps bring enterprise design tasks into focus and produces … EA community to overcome the challenge of stovepipe system have adopt the reference model concept from the network communication practice. . Myth #4, Technical Reference Model as standard profile TRM is the classification and category of IT standards, it is not the standard catalog. Here are the reason for why reference model. . Data Architecture Reference Model 1.0 Introduction First things first: what is a reference model? Then based on these questions, you can develop an approach and identify the models that you need. A Reference Architecture is an anchor for other architecture deliverables; the Business Capability model discussed in Part 1 is an example. EA community have used Technical Reference Model to classify and categorize their technology standards from the beginning of EA. The second reference architecture is the Integrated Information Infrastructure Reference Model (III-RM) [11b]. The scope of reference model encompass all EA related architecture classification such as performance reference model, business reference model, service reference model, data reference model and technology reference model. 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. The application developers are expecting to see architecture best practice in EA rather than EA classification. It establish a common language for the knowledge of reusable resources to learn from the experience of the others. The term of TRM has become the synonymy of standard profile. This was a five-layer reference model that illustrates the interrelationship of business, information system, and technology domains. These elements can also have Tagged Values added to capture additional properties. He was a registered Professional Engineer in the state of Florida since 1981. 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. 4.2 Use reference model to render architecture standards This is the most popular utilization of reference model. Your email address will not be published. In 1989, the National Institute of Standards and Technology (NIST) published the NIST Enterprise Architecture Model. Whereas a reference model divides the functionality, a reference architecture is the mapping of that functionality onto a system decomposition. The Technical Reference Model provide a meaningful standard profile to render the standard list within the context of architecture need. SaaS platform for Enterprise Architecture. Even with a reference model, the challenges can be substantial. As the notional reference model figure below illustrates, reference models capture the elements of the architectural views, and translate those elements into text. 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. Why Architecture Classification?
