An encapsulation of technology infrastructure that represents a class of technology product or specific technology A repository of re-usable solutions for future implementation efforts. The four categories in each are Foundation, Common Systems, Industry and Organizational-Specific. Definitions . A proven enterprise architecture methodology and framework used by the world’s leading organizations to improve business efficiency 2. Although I still produce various types of technology architecture, my work has gradually shifted more towards enterprise architecture. Business IT Interface, Business Process Modeling and Management, Communication, Compliance and Legislation, Computers, Content Various countries and industries employ other It is a tried-and-tested framework that offers guidance on many aspects in enterprise architecture. For a complete list of activities and considerations, see section 46 (version 9.1) of the TOGAF standard. Physical elements in an Enterprise Architecture may still be considerably abstracted from Building Blocks over time. Look to the standard’s section 2.10 (version 9.1) for guidance of blending TOGAF with other frameworks. An abstracted plan for business or technology change, typically operating across multiple disciplines over multiple years. Architecture. But throughout a business’s lifetime, new systems are created, mergers require system integration or consolidation, new technologies are adopted for a competitive edge, and more systems need integration to share information. Agile development methodologies are widely used for developing and delivering technology-based projects in an iterative manner. Lastly, TOGAF acknowledges the occasional need to integrate its standard with other business, project or operation management methods. Examples include identifying and applying architecture principles, leveraging architecture patterns, defining business scenarios and performing gap analysis. Both of the continuum architecture classifications are arranged horizontally – moving from the left (more generic or abstract,) to the right (more specific.) A representation of an end-to-end collection of value-adding activities that create an overall result for a customer, will often span multiple organizations. Project Management, Security, Standards, Storage, Voice and Data Communications. How would you employ the ADM as an enterprise architect, in conjunction with an agile development team? Or better yet, why is enterprise architecture (EA) important? Source: OASIS®; refer to www.oasis-open.org/committees/tc_home.php?wg_abbrev=soa-rm. The goal is to deliver desired outcomes and adhere to An architectural work product that describes an aspect of the architecture. It contains The architect should follow with the Migration Planning tasks (Phase F) and Implementation Governance tasks (Phase G) in the background, while the agile team is developing the solution. The faster the company’s growth, the more imminent the threat becomes. development of consistent standards or specifications supporting that environment. The TOGAF framework has four primary architecture domains: business, data, application, However, adapting TOGAF to Zachman will demonstrate the flexibility of TOGAF. Businesses thrive off change to deliver new products and services to earn revenue and stay relevant. The management of needs of stakeholders of the Enterprise Architecture practice. The organized collection of all architecture views pertinent to an architecture. A particular ability that a business may possess or exchange to achieve a specific purpose. An interest in a system relevant to one or more of its stakeholders. Business Architecture is described in Part II, 7. First, assess the dimensions of the Zachman table model. They may be iterated as a full cycle, adjacently or internally, as … Repository. It is encouraged to review the full standard for a better understanding. See also 3.72 Stakeholder and 3.18 Architecture Viewpoint . As you may see, some of these facets are structures, such as the continuum and repository. stakeholders. The methods noted include identifying the deliverables output from an architecture activity and then identifying in what activity or phase the outputs should be produced. The Open Group Architecture Framework, or TOGAF for short, is an enterprise architecture framework standard created by The Open Group organization. For example, in creating a new target architecture, apply ADM Phases B, C, and D (Business, Information Systems, and Technology Architecture phases) to establish a baseline architecture, then perform a gap analysis to identify pitfalls. It is used for the development and governance of enterprise architectures to adequately address business needs. Supplementary Definitions should be referenced for supplementary definitions not defined in this chapter. A structure for content or process that can be used as a tool to structure thinking, ensuring consistency and completeness. business model. Of those, 25 were implemented and are currently in-use or in a production environment. Ideally, while the enterprise architect is working on his/her analysis, design and deliverables, the agile team is working on completing a prior release. Data about data, of any sort in any media, that describes the characteristics of an entity. . Becoming familiar with the standard replaces the need to reinvent EA processes, practices, structures and principles. In the process diagram, the activities required to be performed are presented as a series of connected activity shapes. cartographic, narrative, or audio-visual forms. A part of the Enterprise Continuum. A set of actions identified to achieve one or more objectives for the business. govern business transformation and implementation projects. For each applicable phase, identify the required inputs and the ideal outputs. A representation of a system from the perspective of a related set of concerns. The core of the TOGAF framework. Up to this point, I have produced 36 architecture designs within the areas of application, integration, cloud, UI, mobile and CI pipeline. The automated elements of a business service. A. Glossary of An enterprise Transition Architecture is described in Part IV, 32.2.3 TOGAF is concerned with quality architecture to meet business strategy. Remember, the development team is depending on you to deliver a quality architecture product. Provides a method to classify architecture and solution assets to provide consistency and promote reuse. It is unlikely for an organization to employ multiple enterprise architecture frameworks simultaneously, though one possible scenario is when a merger is underway. A constituent of the architecture model that describes a single aspect of the overall model. It is enabled by technology services provided by technology The ability of two or more systems or components to exchange and use information. The ADM is an iterative architecture development method, consisting of nine phases, that guides architects and organizations in the development and delivery of architectures. The collection of technology components of hardware and software that provide the services used to support applications. A time-bounded milestone for an organization used to demonstrate progress towards a goal; for example, "Increase capacity Alternate names commonly adopted include Information Services, Information Management, et al. stakeholders. The ability of systems to provide and receive services from other systems and to use the services so interchanged to enable ▪ Guidelines provide alternatives to adapt the ADM process to deal with varying usage scenarios. Foremost, timing is everything. I will then outline its contribution to enterprise architecture, provide guidance on applying it in your organization and explain how to adapt it to other methodologies. TOGAF 9 can be used for developing a broad range of different enterprise architectures. Delivers business capabilities closely aligned to an organization, but not necessarily explicitly governed by the (1) Section 5.2.2, TOGAF 9.1 standard. Share the benefits of adopting a standardized EA framework (such as the TOGAF standard) with others. Ideal timing is to deliver the last enterprise architecture outputs in Phase D just before the development team begins its solution and implementation entering their next agile release. Let’s explore two examples. Agile team delivery should be supported by the ADM Phase H Architecture Change Management tasks. So why is the TOGAF standard important? Leverage the techniques of TOGAF to apply it in your organization. organization. Trying to document all the complexity of large enterprise systems can be overwhelming and difficult to know where to begin. Note: The ADM is described in Part II: Architecture Development Method (ADM). In TOGAF, What is the difference between an artifact and a deliverable? A multi-phase, iterative approach to develop and use an Enterprise Architecture to shape and I wanted to build on my experience in the field, by learning a new discipline. management. Target Architecture is identified. relevant principles, standards, and roadmaps. The part an individual plays in an organization and the contribution they make through the application of their skills, When two companies merge, redundant systems will need to share information or perhaps consolidation will be required. Actors may be internal or external to an organization. A formal description of one state of the architecture at an architecturally significant point in time. provide a foundation on which more specific architectures can be built. Another classic example demonstrating the need for EA is a merger or acquisition. The lifecycle management of information and related technology used by an organization. There is no need to reinvent these on your own. In this organization’s case, the architecture review board structure and activities are home-grown and have evolved over the brief period since the board’s establishment. and technology. Socialize the concepts and terminology with the technical, project, and stakeholder teams throughout the effort. It also manages the execution of communication It is flexible – you may iterate around all eight phases; select only the relevant phases to iterate; iterate repetitively around adjacent phases; or iterate internally within a single phase. (Source: ISO/IEC/IEEE 42010:2011). The standard is a methodology that includes a set of processes, principles, guidelines, best practices, techniques, roles, and artifacts. This chapter defines the deliverables that will typically be consumed and produced across the TOGAF ADM cycle. To demonstrate the value of the TOGAF standard, I will first provide a summary of the standard. Introduction) identifies deliverables that are produced as outputs from executing the ADM cycle and potentially consumed as inputs at other points in the ADM. Other deliverables may be produced elsewhere and consumed by the ADM. Deliverables produced by executing the ADM are shown in the table below.
