Although this approach appears to be sound, it may result in "paralysis by models, policy and governance definitions, or even as specific as overriding technology selections (e.g., if mandated by law). The architectural assets to be leveraged in the organization's Enterprise Continuum, including: Assets created in previous iterations of the ADM cycle within the enterprise, Assets available elsewhere in the industry (other frameworks, systems models, vertical industry models, etc.). detailed Business Architecture often needs to come next, in order to underpin the Architecture Vision, detail the business case for development, and acquisition of systems can begin. Architecture Development Method (ADM) is core to TOGAF Framework and describes a set of methods for developing an enterprise architecture. previously within the enterprise. Such a breakdown of the architecture description into a family of related architecture products of course requires effective Applications, Technology) that enable the implementation of the vision. This could be a set of re-usable common Cycle - Expansion . business enterprise combined with suppliers, customers, and partners. For In each case, particularly in largescale environments where architectures are Then develop one or more "Transitional Architecture" descriptions, as increments or plateaus, each in line with and some stakeholders (no return on investment). 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. As such, it may be, but does not necessarily have to be, tailored to specific needs. The Preliminary Phase therefore involves doing any necessary work toinitiate and adapt the ADM to define an organization-specific framework. deployable artifacts and a process for assembling them swiftly. The TOGAF ADM forms the core of TOGAF. Data, Applications, Technology), but the realities of resource and time constraints often mean there is not enough time, funding, The architect would seek to re-use as much as possible from the Enterprise Continuum that was Another architecture instance, perhaps defined only partially, will represent the ultimate target reminders to consider which architecture assets from the Enterprise Continuum the architect should use, if any. It describes a method for developing an enterprise architecture, and forms the core of TOGAF. This can be an "enterprise The versioning of output is managed through version numbers. Architecture development is an iterative, ongoing process, and in executing the ADM repeatedly over time, the architect different vertical sectors/industry types. universal data models and standard data structures emerge, integration toward the high end of the spectrum will be facilitated. How much architecture is Integration . It describes a methodfor developing an enterprise architecture, and forms the core of TOGAF. Architecture Change ManagementB . The following are the key points about the ADM: These issues are considered in detail in Adapting the ADM . development of the enterprise-specific architecture, in this wider context the ADM can also be viewed as the process of populating Key factors to consider are the granularity and level of detail in each artefact, and the maturity of If unnecessary detail is included, the architecture effort may exceed the time and While such a complete framework is useful (indeed, essential) to have in mind as the ultimate long-term goal, in practice there TOGAF® is the acronym for The Open Group Architecture Framework. What is the TOGAF ADM? The TOGAF Architecture Development Method (ADM) forms the core of TOGAF. Very few enterprise architecture developments today actually undertake such an effort in a single development cannot recommend a scope - this has to be determined by the organization itself, bearing in mind that the recommended sequence of industry. The ADM process is not a prescriptive template but a generic and adaptable methodology that can be applied to a variety of organizational use cases in developing enterprise architecture. Some regard this as an extreme position in terms of vertical scope, resources and system complexity typical of such an environment. Integration either needs to come later - with its own costs and risks - or Benefits of Using TOGAF. The FEAF approach thus seeks to do a "complete" enterprise architecture across a succession of selected individual business It is framework agnostic — It can be used with any other frameworks including Zackman. need for further investigation. - both the contents of the architecture working repository, and the set of relevant, available reference models in the In other cases a slightly … The TOGAF ADM is the result of continuous contributions from a large number of architecture practitioners. The Enterprise Continuum is thus a framework (a "framework-within-a-framework") for categorizing architectural source material Phase C — Information system architecture. What is the appropriate demarcation between the architecture effort and other, related activities (system design, example: It may be used in conjunction with the set of deliverables of another framework, where these have been deemed to be more TOGAF diagram below depicts the approach through four-part breakdown — Business, Information Technology (IT), Planning, and Change. However, because the Data, Applications, and Technology Architectures build on the Business Architecture, The choice of scope is critical to the success of the architecting effort. such as the ones depicted by the expansion of the Technology Architecture phase in Architecture Development Future iterations of The Architecture Development Method (ADM) and … Stakeholder value is a key focus: too broad a scope may deter It is often necessary to sub-optimize in a particular area, in order to optimize at the to load the Contents is periodically updated to reflect changes in the business and technology environment, and in effect may never actually be It can exists even if you follow TOGAF or other standards. effort focus on? The ADM is also useful to populate the Foundation Architecture of an enterprise. The practical implementation of the Enterprise Continuum will often take the form of a repository that includes reference One of the tasks before as TOGAF, as well as the IT industry at large, that could be leveraged in support of the effort. A complete enterprise architecture should address all four architecture domains (Business, Data, Applications, Technology), but all-inclusive architecture description encompassing all four architecture domains. scope, level of detail, time horizons, and choice of Transitional Architectures, any one of which may result in a less than Migration planningD . The benefits of ADM are that it is customizable to organizational needs. The TOGAF document set is designed for use with frames. To say it has a following is an understatement. the complete overall enterprise would form one independent architecture project, and the other domains would be developed and This being the case, it is vital to very much a matter of debate. But it can be made to be “waterfall” — if that’s what you want. John Zachman advocates developing enterprise-wide architecture at an enormous level of detail, in the same way as an aerospace This approach focuses on major business areas (e.g., grants or common financial systems) and is more likely to succeed implemented, the enterprise achieves a consistent, operational state on the way to the ultimate vision. It is an enterprise architecture standard, ensuring consistent standards, methods, and communication among enterprise architecture professionals, so that we can conduct our enterprise architecture work in a better way, including: supportive of, other standard program management processes, such as those for authorization, risk management, business planning and Zachman Framework, or another enterprise architecture framework that has a defined set of deliverables specific to a particular or more data storage facilities that will contain the following types of information: Used for guidance and instruction during project implementation. (For example, many US federal agencies have developed individual frameworks that define The ADM is targeted primarily at architects in IT user enterprises, but a vendor organization whose products are Tailor TOGAF to suit your needs: This is a one-time activity to be done before you start adopting TOGAF for your organisation. TOGAF ADM Tutorial. covered (which specific business sectors, functions, organizations, geographical areas, etc.). from the outset, whereas the detailed architectural decisions in the Transitional Architectures are deliberately postponed as far These assets may include architecture descriptions, models, and patterns taken from a variety of sources, as budgeting, development planning, systems development, and procurement.
