4.4 Use reference model for architecture assessment Governance organization use reference models for the purpose of Enterprise Architecture assessment. The reference model become critical to specify service catalog and service agreement as shown in the ITIL Version 3. Reference model enable EA communication, It is the corner stone of 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. Again, this reference architecture fosters a common vocabulary [Kel11]. Below is a 2d flat version of a simple Enterprise Architecture Meta model of an Organization with 2 business units. 1. 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. Stovepipe systems are created due to lack of horizontal communication, the EA community has adopted the reference model concept to overcome the stovepipe system. The US FEA consolidate reference model is a good start for this purpose. 4.5 Architecture classification for Service Level Agreement(SLA) Information age has evolved toward service oriented architecture, cloud computing and out sourcing. 3.1 The science of EA taxonomy Reference Model serve as the taxonomy of Enterprise Architecture. 7.5.2 Developing the Baseline Description. 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.

Save my name, email, and website in this browser for the next time I comment. THE IMPLEMENTATION OF REFERENCE MODEL Reference model must be maintained and modified for practical use. 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 Article byThe UX Blog 5. are described as “standardized architectures that provide a frame of reference for a particular domain This Foundation Architecture is embodied within the Technical Reference Model (TRM), which provides a model and taxonomy of generic platform services. Application Portfolio Management: how to create effective application landscapes? Below you see the most recent version of the Dragon1 Enterprise Architecture Reference model. The Common Approach to Federal Enterprise Architecture also defines a Consolidated Reference Model.This framework establishes a common language to describe and analyze investments. Whereas a reference model divides the functionality, a reference architecture is the mapping of that functionality onto a system decomposition. Initially, ITIL only address IT management and gradually evolved to all services in ITIL V3. The consolidation reference further demonstrate that reference model is all about Enterprise Architecture classification and have nothing to do with architecture approach. Enterprise Architecture Capability Reference Model The Enterprise Architecture Capability Reference model is represented by a simple graphic and a complete textual description. Architecture approaches for Microsoft cloud tenant-to-tenant migrations. 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 most popular reference model is the Open System Interconnection(OSI) Reference Model. 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. The ARM is a component-driven taxonomy that categorizes the system and application related standards and technologies that support and enable the delivery of service components and capabilities. 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 … However, reference model are used to classify an organizations architecture category rather than serve as an architecture best practice. In this article, I will introduce another helpful deliverable called Enterpris… Required fields are marked *, You may use these HTML tags and attributes:
. 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.) Reference model enable Service Level Agreement(SLA) as the the information age culture evolved to out sourcing, service oriented architecture and clouding computing. 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. Data Architecture Reference Model 1.0 Introduction First things first: what is a reference model? The framework is made up of six reference models that can be used with some latitude to apply to private sectors: 1. Architecture classification to speak the language become essential for preparing Device Level Agreement between the parties of SOA, Cloud computing and Out sourcing. The second reference architecture is the Integrated Information Infrastructure Reference Model (III-RM) [11b]. They define the infrastructure as well as the skills and procedures needed for the implementation of the respective system [Nie08]. Re-use this reference model to make it part of your enterprise meta model. It is crucial to establish an international Enterprise Architecture classification based on the science of Taxonomy. An Enterprise Architecture Framework defines in a series of reference models, how to organize the structure and views associated with an Enterprise Architecture. The model provides a taxonomy for classifying the technology assets. A framework helps bring enterprise design tasks into focus and produces … Then based on these questions, you can develop an approach and identify the models that you need. People come to TRM to look for the technology standard rather the architecture classification. Enterprise Architects must be familiar with reference model for architecture classification. Rather, they are used as a constraint for more concrete architectures. The Enterprise Architecture Capability Reference model is represented by a simple graphic and a complete textual description. The Data Reference Model (DRM) is one of the five reference models of the Federal Enterprise Architecture (FEA). It … Business Architecture. It also can be used to establish service level agreement and Enterprise architecture mark up language. A Reference Architecture is an anchor for other architecture deliverables; the Business Capability model discussed in Part 1 is an example. And of course you can alter the reference model to your own theory about enterprise strategy. The notion of Reference model for architecture assessment have dim the value of architecture classification in the EA global EA community. Taxonomy is the practice and science of classification. The use of reference model. The purpose of the FEAF is to facilitate shared development of common processes and information among Federal Agencies and other government agencies. He was a registered Professional Engineer in the state of Florida since 1981. Reference model is the corner stone for EA to line up rather than an architecture best practice. Introduction 1.1 Purpose. The architecture classification is well defined with a code, a name and description to avoid miss communication. This Foundation Architecture has two main elements: The Technical Reference Model (TRM), which provides a model and taxonomy of generic platform services 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. 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. It can become an important part to agile software delivery. Nodes below this root are more specific classifications that apply to subsets of the total set of classified objects. 2.3 Architectural Patterns, Reference Models, and Reference Architectures. This reference architecture is composed of a long list of application components and services necessary to enable the services defined in the TRM. Originality, Enterprise Architects classify their enterprise architecture for the purpose of architecture communication to reuse, share and learning the right experiences from each other. Dragon1, SaaS platform for Enterprise Architecture.The #1 EA Tool, DEMO: Generate an interactive Process Application Map using your own data. Why Architecture Classification? Central to the Reference Architecture are the EA purposes. Integration must now treat cloud as a first-class citizen and cater to radically different requirements from a broader range of users. THE CHALLENGE OF REFERENCE MODEL The challenge of reference model is to establish a common reference model in the Enterprise Architecture community. It can become an important part to agile software delivery. 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. 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… The discipline of EA, views an organization as an overall system of complex and intertwined systems. 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. Originally taxonomy referred only to the classifying of organisms (now sometimes known as alpha taxonomy) or a particular classification of organisms. To keep the reference model simple, the group of reference model is consolidated to become the consolidate reference model. This was a five-layer reference model that illustrates the interrelationship of business, information system, and technology domains. Effective management of such complexity and scale requires tools and approaches that architects can use. You can re-use this reference model to make it part of your enterprise meta model on Dragon1. WHY 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. "John Chizong Wu has actively participated and advocate practical Enterprise Architecture approach in the Washington DC area since 1998. Here are the reason for why reference model. The Application Reference Model (ARM) supports architectural analysis and reporting in the applications sub-architecture view of the overall EA. EA industry have used Technical Reference Model to classify their technical standards. Reference models or architectures provide a common vocabulary, reusable designs and industry best practices. The most difficult thing in EA is to get Enterprise Architects to talk in the same language. of Civil engineering form Howard University in 1979 and M.S. 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. Collectively, the reference models comprise a framework for describing important elements o… The US government establish the Federal Consolidate Reference Model and the British government establish ITIL and Cobit. 2.2 EA classification for Service Level agreement. And of course you can alter the reference model to your own theory about enterprise strategy. in Computer Science from Florida Institute of Technology in 1984. It also provides a common vocabulary with which to discuss implementations, often with the aim to stress commonality. 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. Agile enterprise architecture -- which focuses an organization around a flexible, extended collection of structures and processes that can grow. Reference model enable enterprise architecture to learn from the right resources. 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. EA community to overcome the challenge of stovepipe system have adopt the reference model concept from the network communication practice. Enterprise Architecture Domains > Business Architecture > Business Models > Business Information Model > Reference Data Data that is used to define or describe other data. 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. This article considers the primary drivers of change and the integration reference architecture that is evolving to meet the new demands. Myth #1, Developing reference Model EA professional are asked to develop reference model where the reference models are considered as an architecture best practice. 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. It is an Enterprise Architecture classification effort to support EA communication on the same page. 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 implementation of reference model 1. 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. EA community have used Technical Reference Model to classify and categorize their technology standards from the beginning of EA. May 8, 2017 - Enterprise Architecture Reference Model is a Dragon1 reference model for EA. 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. For more detail on the please link to the FEAPMO reference model. However, ITIL and Cobit from British government have become popular in many countries and gaming support in the international EA community. These elements can also have Tagged Values added to capture additional properties. 3.2 The Scope of Enterprise Architecture Reference Model The scope of Enterprise Architecture Classification is not only about Information Technology. The FEA has five reference models. 2.3 EA classification to see the big picture of EA. 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  . Newsletters may contain advertising. Both the United States government and the British government have invested on architecture classification. The OMB reference model has not become popular as expected due to lack of continuous maintenance. Within Enterprise Architect, this graphic also serves as a mechanism for navigating through the model. The Technical Reference Model ensures that architectures are created consistently and repeatedly based on a standard set of elements. 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. The application developers are expecting to see architecture best practice in EA rather than EA classification. The principles apply to all IT projects and architecture-related work. The Technical Reference Model provide a meaningful standard profile to render the standard list within the context of architecture need. It is part of EA discipline. EAM Reference Model & Reference Architecture Foundations Reference models and reference architectures are abstract solution patterns for the design of systems in a specific domain . Even with a reference model, the challenges can be substantial.
