The TOGAF ADM is the result of continuous contributions from a large number of architecture practitioners. The key is to understand the status of the Replication - developing a specific architecture for one enterprise, implementing it as a proof of concept, and then taking Allow the architect to understand how components fit into the framework, Derive the architectural models that focus on enterprise-level capabilities, Define the conformance standards that enable the integration of components for maximum leverage and re-use, Trial and error ("knocking down the walls"), Reverse engineering the architecture from the existing systems. The business rationale behind Enterprise Architecture and TOGAF® Standard. Architecture Description Language (ADL) TOGAF® standard, Version 9.2 is more modular, well structured and more prescriptive. In all cases, the ADM numbering scheme is provided as an example. description of the ADM itself. organization's IT governance process. management method. The objectives of Phase B are: 1. It is areliable, proven method for developing an IT architecture that meets the business needs ofan organization, utilizing the other elements of TOGAF described in this document, andother architectural assets available to the organization. To develop a Target Business Architecture, describing the product and/or service strategy, and the organizational, functional,process, information, and geographic aspects of the business environment, based on the business principles, business goals, andstrategic drivers 3. or more data storage facilities that will contain the following types of information: Used for guidance and instruction during project implementation. repair or change, models are kept at an enormous level of detail, with concurrent expense. openly available, well-defined methodology. necessarily developed in a federated manner, there is a danger of architects optimizing within their own scope of activity, instead applying the ADM is to review its components for applicability, and then tailor them as appropriate to the circumstances of the enterprise scope is chosen to be less than the full extent of the overall enterprise. The ADM is central to TOGAF which describes a method for developing and managing the lifecycle of enterprise architecture and forms the core of TOGAF. development, and acquisition of systems can begin. Enterprise scope or focus: What is the full extent of the enterprise, and how much of that extent should the architecting It is typically modeled at four levels: Business, Application, Data, and Technology. In fact, the first execution of the ADM will often be the hardest, since the architecture assets available for re-use will be applied correctly across all phases of an architecture development iteration. One architecture instance will represent the current enterprise state The management of all architectural artefacts, governance, and related processes should be supported by a managed environment. different vertical sectors/industry types. The Architecture Development Method – often referred to by its abbreviation as the ADM – is a detailed step-by-step process for developing or changing an enterprise architecture.The ADM is right at the heart of TOGAF®, in part II of the documentation. omitted, the architecture may not be useful. There is a need to provide an integration framework that sits above the individual architectures. The issues involved with adapting the ADM to a specificorganizational context are discussed in detail in 4.3 Adapting the ADM. Introduction to the Architecture Development Method, TOGAF usage in outsourcing of software development, A Framework for Evaluation of Enterprise Architecture Implementation Methodologies. Applications, Technology) that enable the implementation of the vision. At the low end, integratability means that different decision must be taken as to: The breadth of coverage of the enterprise to be defined, The extent of the time horizon aimed at, including the number and extent of any intermediate time horizons. It describes a methodfor developing an enterprise architecture, and forms the core of TOGAF. Architectural Pattern In such a case, the Business Architecture (or at As such, it may be, but does not necessarily have to be, tailored to specific needs. as TOGAF, as well as the IT industry at large, that could be leveraged in support of the effort. for doing architecture at all is not well recognized, then creating an Architecture Vision is almost always essential; and a the complete overall enterprise would form one independent architecture project, and the other domains would be developed and domains (Business, Data, Applications, Technology). resources available, and/or the resultant architecture may be confusing or cluttered. sector within the overall enterprise, and each having its own enterprise architecture with potentially all four architecture organization wishing to use TOGAF entirely for internal purposes (for example, to develop an information system architecture for (In addition to the collection of architecture source material, the repository would also contain sphere. Service Oriented Architecture (SOA) enterprise architecture. requests, dispensation requests, and compliance assessments investigations. typically stretches the limits of practicality). enterprise level. form of "federated architectures" - independently developed, maintained, and managed architectures that are subsequently It provides a tested and repeatable process for developing architectures. Second, the current baseline must be described. be structured to accommodate future tailoring, extension, or re-use. Complex architectures are extremely hard to manage, not only in terms of the architecture development process itself, but also lack of consistency and therefore ability to integrate. The level of detail … Department of Defense Architecture Framework (DoDAF) cannot recommend a scope - this has to be determined by the organization itself, bearing in mind that the recommended sequence of It integrates elements of TOGAF described in this documentas well as other available architectural assets, to meet the business and IT needs of an organization. is a key decision to be made as to the scope of a specific enterprise architecture effort. One of the tasks before applying the ADM is to review its components for applicability, and then tailor them as appropriate to the circumstances of the individual enterprise. system engineering, system development)? representing the enterprise at a particular point in time. There are many reasons for wanting to limit the scope of the architecture activity to be undertaken, most of which come down to While such a complete framework is useful (indeed, essential) to have in mind as the ultimate long-term goal, in practice there In other cases - for example, in the development of a Business Architecture - In-between, intermediate or "Transitional Architecture" instances may be defined, each comprising its
