Build object models to flesh out the Custom List as the underlying information model for the Enterprise Architecture catalogs. Powered by TCPDF (www.tcpdf.org) 4 / 4 Throughout the development of architecture a huge volume of architectural output will be created. When this occurs the requirements are met and archived for audit purposes. In a typical enterprise, many architectures will be described in the Architecture Landscape at any given point in time. - Identify candidate Architecture Roadmap components based upon gaps between the Open the Architecture Repository, double click on the corresponding boxes (known as drawers) and add your files into them. Architecture Partitioning and Part III, 20. The architecture repository occupies a central position in TOGAF as a tool for capitalizing, reusing, and structuring information. Avoid lock-in to proprietary solutions b… There are many industry reference models available which may assist in understanding the role of and developing the Reference Architectures. Justification for major architectural features of projects, Progress overview (timeline, status, issues, risks, dependencies, etc. At a high level, six classes of architectural information are expected to be held within an Architecture Repository: The relationships between these areas of the Architecture Repository are shown in Figure 41-1. See Figure 41-1. To address this complexity TOGAF uses the concept of levels and the Enterprise Continuum to provide a conceptual framework for organizing the Architecture Landscape. The TOGAF standard includes the Technical Reference Model (TRM) as its Foundation Architecture. Alternatively, drag file(s) directly into a drawer. Provides a record of governance activity across the enterprise. 1: Enterprise. This section of TOGAF provides a structural framework for an Architecture Repository that allows an … TOGAF is a high-level approach to design. The Architecture Content Metamodel (i.e. To navigate around the document: Downloads of TOGAF®, an Open Group Standard, are available under license from the TOGAF information web site. The TOGAF Enterprise Continuum is a 'virtual repository' of all the architecture assets - models, Patterns, architecture descriptions and other artifacts - that exist both within the enterprise and in the IT industry at large, and that the enterprise considers itself to have available for … Provides guidelines, templates, patterns, and other forms of reference material that can be leveraged in order to accelerate the creation of new architectures for the enterprise. Get Stuck in! This view is used at the portfolio management level for supporting planning. Applying the ADM across the Architecture Landscape). These output will be used as references in completing the other part of the development phases, or as inputs of future architecture development activities. Which one of the following statements about the structure of the TOGAF 9 document is true? It is based on an iterative process model supported by best practices and a re-usable set of existing architecture assets. The Architecture Repository provides you with a free and flexible logical structure you can store your data items. categories of building blocks, as defined for the organization), The set of artifacts (or viewpoints) as defined for the organization, The management and development of the enabling capabilities (including training and certification of the architects, management and development of the Enterprise Continuum, development of new processes, etc. Without it you can't get full value from your models.

Particularly in larger enterprises, Architecture Boardst… These minutes are often held in documentation archives which are excluded from the Architecture Repository for legal or regulatory reasons. TOGAF helps businesses define and organize requirements before a project starts, keeping the process moving quickly with few errors. TOGAF Architecture Repository TOGAF states that a mature architecture capability requires an Architecture Repository in order to structure all of the information generated and managed by the architecture team. The Architecture Landscape holds architectural views of the state of the enterprise at particular points in time. Figure: TOGAF Architecture Repository Structure. Relating Architecture Repository Framework with others TOGAF describes the structure and content of the repository areas that hold the output of projects, namely the Architecture Landscape, the Reference Library, the Standards Information Base, and the Governance Log. Key enhancements made in this version include updates to the Business Architecture and the Content Metamodel. Effective management and leverage of these architectural work products require a formal taxonomy for different types of architectural asset alongside with dedicated processes and tools for architectural content storage. TOGAF v9 Part 6 . The license is free to any organization wishing to use the TOGAF standard entirely for internal purposes (for example, to develop an information system architecture for use within that organization). The goal consists of finding practices accumulated during previous ADM cycles to progressively constitute an asset available to the entire enterprise. The Architecture Repository acts as a holding area for all architectural assets within an enterprise. This sometimes goes against principles, but when starting out, just getting going and … The requirements address the many types of architecture requirements; i.e., strategic, segment and capability requirements which are the major drivers for the enterprise architecture. In this case the TOGAF ADM will be used. Part II, the Architecture Development Method, describes the definitions of terms used in TOGAF, and the changes between versions of TOGAF Choose from 171 different sets of TOGAf flashcards on Quizlet. TOGAF provides the methods and tools for assisting in the acceptance, production, use, and maintenance of an enterprise architecture. Architecture Continuum The Architecture Continuum can be viewed as a Reference Library classification scheme. ArchitectureGovernance) is a cross-organization Architecture Board to oversee the implementation of the strategy. ArchiRepo, in connection with the ArchiMate tools (such as open-source Archi), offers a complex solution of enterprise architecture. Data Architecture 3. What is the TOGAF Architecture Repository? If you have any reference documents you can add them now into the Architecture Repository. The Standards Information Base provides a repository area to hold a set of specifications, to which architectures must conform. A cabinet is the highest structure element. Architecture Boards may have global, regional, or business line scope. A book is also available (in hardcopy and pdf) from The Open Group Bookstore as document G116. For example, if a system is to be replaced, having sight of the key architectural decisions that shaped the initial implementation is highly valuable, as it will highlight constraints that may otherwise be obscured. Relationships between Deliverables and Architecture Repository. A key element in a successful Architecture Governance strategy (see 44. It is typically modeled at four levels: Business, Application, Data, and Technology. The act! The Open Group Architecture Framework (TOGAF) is the most used framework for enterprise architecture today that provides an approach for designing, planning, implementing, and governing an enterprise information technology architecture. Learn how to create yours! ), Demand management and monitor of request for changes. Through this exercise it is important to keep in mind the concepts of levels and partitions. Part I, the Enterprise Continuum, describes a model for structuring a virtual repository B. It may be used freely by any organization planning to develop an enterprise architecture . The structure of the TOGAF Architecture Repository is shown in TOGAF Architecture Repository Structure. This document describes the TOGAF Architecture Repository. The architect will typically find more re-usable architectural elements toward the left of the range. Each domain has to: - Develop the Target Architectures in a way that addresses the Request for Architecture Work and stakeholder concerns. TOGAF provides a structural framework for such Repository. This section of TOGAF provides a structural framework for an Architecture Repository that allows an enterprise to distinguish between different types of architectural assets that exist at different levels of abstraction in the organization. As it illustrates how reference architecture… The enterprise repository is divided into three repositories; TOGAF is centred on the architecture repository. Many stakeholders are interested in the outcome of project governance (e.g., other projects, customers of the project, the Architecture Board, etc.). These include the Requirements Repository storing requirements and the Solutions Repository storing Solution Building Blocks (SBBs). Effective management and leverage of these architectural work products require a formal taxonomy for different types of architectural asset alongside dedicated processes and tools for architectural content storage. This view is used at the executive level for setting directions. Defines the parameters, structures, and processes that support governance of the Architecture Repository. 10 - According to TOGAF, which one of the following is described as a view of the Architecture Repository and provides methods for classifying architecture and solution artifacts as they evolve? This Architecture Repository is one part of the wider Enterprise Repository, which provides the capability to link architectural assets to components of the Detailed Design, Deployment, and Service Management Repositories. Capability architectures: detailed models of building blocks, describing the units of capability (application component models, data element models, technology component models). Like other IT management frameworks, TOGAF helps businesses align IT goals with overall business goals, while helping to organize cross-departmental IT efforts. As such it illustrates how reference architectures can be organized across a range - from Foundation Architectures, and Industry-Specific Architectures, to an Organization-Specific Architecture. The Open Group Architecture Framework (TOGAF) is a framework – a logical model, a detailed method and a set of supporting tools - for developing enterprise architecture. The Solutions Repository holds the Solution Building Blocks (SBBs). The TOGAF Standard, Version 9.2, is an update to the TOGAF 9.1 standard providing improved guidance, correcting errors, improving the document structure, and removing obsolete content. – reference model for enterprise architecture management t-eam* is assembled from separately usable components :" process templates p-arc, p-fach, p-anw, p-sys und p-soft, " reference architecture („blueprint“) ref-arc," meta model and enterprise architecture repository m-arc, The Architecture Continuum, as shown in Figure 41-2, can be viewed as a Reference Library classification scheme. Establishment of a Standards Information Base provides an unambiguous basis for architectural governance because: Standards typically fall into three classes: Standards do not generally exist for all time. The TOGAF document set is designed for use with frames. As a part of standards lifecycle management, the impact of changing the lifecycle status should be addressed to understand the landscape impact of a standards change and plan for appropriate action to address it. Learn TOGAf with free interactive flashcards. ), Templates and reference models for executing Capability Assessments, IT capability, maturity, and impact assessments, Architectural roles and responsibilities associated with the project. Just-In-Time Process - TOGAF Template Just-in-Time Process targets for a dynamic and loose process which provides structure and direction on a preferred way to do something without being too detailed or restrictive. Relating Architecture Repository Framework with others. A modeling repository is a vital resource. Copyright © 2021 Visual Paradigm Community Circle |, 6. Decisions made during projects (such as standards deviations or the rationale for a particular architectural approach) are important to retain and access on an ongoing basis. While deliverables are automatically archived, you can also put a file into a drawer (in the Architecture Repository) manually. A. Deliverables represent the output of projects and those deliverables that are in documentation form will typically be archived at completion of a project, or transitioned into an Architecture Repository as a reference model, standard, or snapshot of the Architecture Landscape at some point. At different levels of granularity there may exist reference materials appropriate to the level, and partitions within the Architecture Landscape can be expected to use different reference material (see 40. Open the Architecture Repository, double click on the corresponding boxes (known as drawers) and add your files into them. A. Architects are expected to structure and index the repository for ease of access - using structuring and indexing devices such as the enterprise continuum. This section of TOGAF describes the structure and content of the repository areas that hold the output of projects, namely the Architecture Landscape, the Reference Library, the Standards Information Base, and the Governance Log. Organization specific architectures (developed in previous engagements and re-worked for later reuse). Strategic architectures: show a long-term summary of the entire enterprise. This view is used for defining the work packages. Avancier Technology architecture Application architecture Business Maintaining a shared repository of governance information is important, because: The Governance Log should contain the following items: While the Architecture Repository holds information concerning the enterprise architecture and associated artifacts there are a considerable number of enterprise repositories that support the architecture. Phase H – Architecture Change Management. Architecture Landscape B. The Architecture Repository acts as a holding area for all architectural assets within an enterprise. Examples include MDA from OMG, FEA for US Government, TMF from the Telecoms Industry, SOA reference models from OASIS and The Open Group. The TOGAF TRM describes a fundamental architecture upon which other, more specific, architectures can be based. When elements are not found, the requirements for the missing elements are passed to the left of the range for incorporation. D. The TOGAF ADM is the core of TOGAF and describes the step-by-step approach to developing an Enterprise Architecture. Describes the organizationally tailored application of an architecture framework, including a method for architecture development and a metamodel for architecture content. Operating a mature Architecture Capability within a large enterprise creates a huge volume of architectural output. Standards may relate to "approved" building blocks (e.g., a list of standard Technology Components) or may specify appropriate use of a building block (e.g., scenarios where messaging infrastructure is appropriate, application communication standards are defined). Operating a mature Architecture Capability within a large enterprise creates a huge volume of architectural output. This body should berepresentative of all the key stakeholders in the architecture, and will typically comprise a group of executives responsible forthe review and maintenance of the overall architecture. Let’s review different class of architecture information and the interrelationships. The business outcomes for requirements will be reflected in the Solutions Repository over time. Standards within the Standards Information Base are categorized according to the building blocks within the TOGAF content metamodel. These relate to industry, best practice, or formal defined standards used by leading organizations. The Structure Of The Togaf Document Information Technology Essay. 3. Structure the Wiki page with a combination of Sub-pages, using SharePoint web parts such as Custom List, Document Libraries. Captures the standards of which new architectures must comply, it may include industry standards, selected products and services from suppliers, or shared services already deployed within the organization. A cabinet contains one or more dossiers. As it illustrates how reference architectures can be organized across a range – from Foundation Architectures, and Industry-Specific Architectures, to an Organization-Specific Architecture. Presents an architectural representation of assets in use, or planned, by the enterprise at particular points in time. Applications Architecture 4. It includes administration of business and Information Technology architecture of an institution or enterprise. Requirements can be gathered at every stage of the architecture development lifecycle and need to be approved through the various phases and governance processes. It allows project team to manage deliverables and locate re-usable assets in a systematic way. Typically, standards pass through the following stages: All standards should be periodically reviewed to ensure that they sit within the right stage of the standards lifecycle. Examples include ISO, IEEE, and Government standards. At a high level, six classes of architectural information are expected to be held within an Architecture Repository: The list below categorizes typical architectural information into the six classes. Ensure everyone speaks the same language 2. TOGAF is an architecture framework – The Open Group Architecture Framework. Title: TOGAF® Version 9 Foundation Study Guide 4th Edition Subtitle: Preparation for the TOGAF 9 Part 1 Examination Series: TOGAF Series A Publication of: Th e Open Group Author: Prof. Rachel Harrison and Andrew Josey Publisher: Van Haren Publishing, Zaltbommel, www.vanharen.net ISBN Hard copy: 978 94 018 0289 5 ISBN eBook (pdf) 978 94 018 0290 1 Architecture Repository Architecture Requirements Architecture Roadmap Architecture Vision ... and file systems. The Architecture Continuum can be viewed as a Reference Library classification scheme. The enterprise needs and business requirements are addressed in decreasing abstraction from left to right. Frequently Asked Questions explains that there are four kinds of ``architecture'' that are commonly accepted as subsetsof an overall enterprise architecture: 1. Business Architecture 2. Let’s review different class of architecture information and the interrelationships. New standards are identified and managed through a lifecycle process. The TRM has two main components: 1. Support of imports and exports not only in the ArchiMate Model Exchange File format. This is a structure for storing all the outputs of the ADM. Effective management and leverage of these architectural work products require a formal taxonomy for different types of architectural asset alongside dedicated processes and tools for architectural content storage. The TOGAF 9.1 core metamodel provides a minimum set of architectural content to … This section also discusses requirements to be considered when selecting tools to manage an Architecture Repository. Segment architectures: showing operating models for areas within an enterprise (business functions, business services, process models). The Enterprise Repository structure. If you have any reference documents you can add them now into the Architecture Repository. Reference materials held may be obtained from a variety of sources, including: In order to segregate different classes of architecture reference materials, the Reference Library can use the Architecture Continuum as a method for classification. The organization-scope is the primary consideration. There are three structure elements: Cabinets, Dossiers and Folders. Phase C – Information Systems Architectures, Architecture Contract with Business Users, Architecture Contract with Development Partners, 11. Technology ArchitectureThe combination of Data Architecture and Applications Architecture is also referred to as the Information SystemArchitecture.TOGAF was originally designed to support the last of these - the Technology Architecture. Alternatively, drag file(s) directly into a drawer. The major components within the structure of the repository are: Architecture Metamodel: Architecture Capability; Architecture Landscape: What building blocks are in use in the organisation today. That enterprise architecture ensures appropriate traceability from business architecture to the other allied architectures. Architecture Governance Repository C. Enterprise Continuum D. Governance Log E. Standards Information Base Preliminary Phase: Architecture Principles, Architecture Repository, Business Principles-Goals-Drivers, Organizational Model for Enterprise Architecture, Request for Architecture Work, Tailored Architecture Framework; Phase A: Architecture Vision, Capability Assessment, Communications Plan, Statement of Architecture Work Each metamodel entity can potentially have standards associated with it (e.g., Business Service, Technology Component). Decisions made by the Architecture Board which affect the enterprise architecture are often recorded in the minutes of meetings. Some will address detail; some will provide a big picture. TOGAF describes the structure and content of the repository areas that hold the output of projects, namely the Architecture Landscape, the Reference Library, the Standards Information Base, and the Governance Log. At the top level, standards are classified in line with the TOGAF architecture domains, including the following areas: The Governance Log provides a repository area to hold shared information relating to the ongoing governance of projects. Although Phases B, C and D deal with different architecture domains, the basic structure for each Phase is very similar. The Requirements Repository is used by the Requirements Management Phase of the Architecture Development Method (ADM) to record and manage all information relevant to the architecture requirements. Due to the sheer volume and the diverse stakeholder needs throughout an entire enterprise, the Architecture Landscape is divided into three levels of granularity: The Reference Library provides a repository to hold reference materials that should be used to develop architectures. TOGAF and Thomas Erl emphasize to define the “Enterprise” in EA clearly and unambiguously. The iServer Explorer folder structure in the repository is configured to support iterations of the TOGAF ADM, and is aligned to the appropriate phases of the ADM. For each phase, there is a complete set of diagrams and documentation templates, along with supporting reference materials, such as BPMN 2.0 process diagrams, which show the activities to be performed. C. The TOGAF ADM is a selection of architectural reference models and include the TOGAF Foundation Architecture, and the Integrated Information Infrastructure Reference Model (III-RM). The standards are easily accessible to projects and therefore the obligations of the project can be understood and planned for, Standards are stated in a clear and unambiguous manner, so that compliance can be objectively assessed, Security and governance standards for business activity, Standards for origin and ownership of data, Standard/shared applications supporting specific business functions, Standards for application communication and interoperation, Standards for access, presentation, and style. Some architecture will address very specific needs; others will be more general. With an enterprise architecture tool using the TOGAF 9.1 artifacts.
