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. 5. informational contents, presentation formats, typical use cases, lifecycles and purposes (see Enterprise architecture on a single page). 3.2 The Scope of Enterprise Architecture Reference Model The scope of Enterprise Architecture Classification is not only about Information Technology. Maracanã, 229 – Rio de Janeiro Goran D. Putnik, D.Sc. EA documents the structural and behavioural building blocks that 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. It is critical to have a common reference model to facilitate the communication handshake. 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. 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 Create your account to get started. Nodes below this root are more specific classifications that apply to subsets of the total set of classified objects. The OMB reference model has not become popular as expected due to lack of continuous maintenance. It is important to establish international Enterprise Architecture classification so the all the Enterprise Architects can speak the same EA language. The US FEAPMO Consolidate Reference model has been a very visionary EA classification effort tie the different reference model together. 2.3 Architectural Patterns, Reference Models, and Reference Architectures. 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. And of course you can alter the reference model to your own theory about enterprise strategy. Performance Reference Model The Performance Reference Model (PRM) supports architectural analysis and reporting in the strategy sub-architecture view of the overall EA. 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. A Reference Architecture is an anchor for other architecture deliverables; the Business Capability model discussed in Part 1 is an example. 7.5.2 Developing the Baseline Description. Business Architecture. 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. . 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. EA industry have used Technical Reference Model to classify their technical standards. 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. http://www.slideshare.net/wuchizong. If an enterprise has existing Architecture Descriptions, … To develop a useful enterprise architecture (EA) it is important to first understand the questions you want to answer with your architecture. Below you see the most recent version of the Dragon1 Enterprise Architecture 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 model provides a taxonomy for classifying the technology assets. To keep the reference model simple, the group of reference model is consolidated to become the consolidate reference model. A reference models are used for architecture classification to enable communication rather than for architecture compliance. 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. Whereas a reference model divides the functionality, a reference architecture is the mapping of that functionality onto a system decomposition. Reference model enable reuse, sharing and learning experience from each other to overcome the challenge of stovepipe system. Enterprise Architects must be familiar with reference model for architecture classification. It is far from a mature Enterprise Architecture classification. The Data Reference Model (DRM) is one of the five reference models of the Federal Enterprise Architecture (FEA). 3.3 The Structure of Reference Model Reference model as taxonomy is in a hierarchical structure. The Architect… The application developers are expecting to see architecture best practice in EA rather than EA classification. 6. The Cloud Ecosystem Reference Model should be considered as an extension of an Enterprise Architecture Model. example: The US OMB have use their consolidate reference model for the purpose of Enterprise Assessment. This article considers the primary drivers of change and the integration reference architecture that is evolving to meet the new demands. The Myth of reference model. It … WHY REFERENCE MODEL? Save my name, email, and website in this browser for the next time I comment. It can become an important part to agile software delivery. In module two we introduced you to a Technology Reference Model. For example: reference model tree in the US FEA Consolidate Reference Model. "John Chizong Wu has actively participated and advocate practical Enterprise Architecture approach in the Washington DC area since 1998. It establish a common language for the knowledge of reusable resources to learn from the experience of the others. Enterprise Architecture Principles based on the IT Strategy and industry best practice. All these layers and entities are part of a container entity like 'Enterprise', 'Organization' or Company. Stovepipe systems are created due to lack of horizontal communication, the EA community has adopted the reference model concept to overcome the stovepipe system. 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. 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.
