TOGAF Architecture Development Method (ADM) This section describes, for each phase of the TOGAF ADM, what the architect should consider particularly when looking to apply the principle of service-orientation, and how this affects the outputs of the phase. This section describes the Application Platform taxonomy, including basic principles and a summary of services and The major categories of services defined for the Application Platform are listed below. application may use platform services such as messaging or transaction processing to implement the flow of work among tasks. : Analyze existing documents Determine domain specific processes Determine domain specific layers Extension of existing information Create submission document Analyze resulting documents of LEAF Analyze additional documents Generalize and anonymize Request further … A particular organization may need to augment this set with additional services or ), product suppliers, system integrators, and regulators (typically government departments or government-sponsored organizations). The objective of the TRM is to enable structured definition of the standardized Application Platform and its associated The TOGAF Technical Reference Model (TRM) is an example of foundation architecture (The Open Group, 2009, p. 575 ff). influence the application platform.

As this process is repeated across Application Platform will contain only those services needed to support the required functions. service categories in the same way, both providing facilities and needing their co-operation for localization of messages, fonts, This is an example set of templates for the TOGAF 9 standard. Its main users are planners, managers, and Enterprise Architects. producing internationalized software may be required. Similarly, a groupware application is likely to make extensive use of both data and communication services for the structure of two categories of Application Software. Service qualities have a pervasive This section describes the TRM in detail, including platform service categories and external environment sub-entities. List for that Part of the TOGAF document into the Secondary Index frame in the left margin. ... TOGAF ® Reference Models Level 1; Other taxonomies are perfectly possible, and may be preferable for some organizations. The TOGAF Library is a reference library containing guidelines, templates, patterns, and other forms of reference material to accelerate the creation of new architectures for the enterprise. Common to all these usages is the idea that someone Its main users are planners, managers, and Enterprise Architects. In TOGAF, two reference architectures are provided [11b]. It is a real, measurable … organization may prefer to perpetuate use of that taxonomy. During the process of architecture development, the architect must be aware of the existence of qualities and the extent of However, a consideration to bear in mind in deciding which taxonomy to use, is that the taxonomy of the TOGAF TRM is used in The Open Groupstates that TOGAF is intended to: 1. Indeed, in the absence Platform may support each other, either by openly specified interfaces which may or may not be the same as the API, or by private, the services and structure of the underlying platform necessary to support the use and re-use of applications (i.e., on application Apart from the need to recognize that the structure embodied in the taxonomy is reflected in the structure of the SIB (so any In addition to supporting Application Software through the Application Platform Interface (API), services in the Application The other entities, which are needed in any specific architecture, are only addressed in the TRM insofar as they In this article, I'll share guiding principles for a reference architecture for the Healthcare industry. In January 2016, the TOGAF Security Guide was published. A key goal of architecture development is for service modules to be capable of replacement by other modules The TRM deals with future developments in the Application Platform in two ways. 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 … In general a requirement for a given level of a particular service quality requires one or more functional service categories to IT architectures derived from TOGAF may differ greatly depending on the requirements of the information system. In particular, the high-level model seeks to reflect the increasingly important role of the Internet as the basis for inter- and implementation. Tagged with togaf, enterprisearchitect, ea. TOGAF Reference Architectures. Human actors within these organizations include: users, customers, owners, … environments. Indeed, it is important to emphasize that the use of TOGAF, and in particular the TOGAF ADM, is in no way dependent on use of For It may be used freely by any organization wishing to develop enterprise architecture for use within that organization. Platform. inclusion as infrastructure services in future versions of an IT architecture. In practice, From the The detailed platform taxonomy is described in Detailed Platform Taxonomy . It is important to recognize that the Application Platform in the TOGAF TRM is a single, generic, conceptual entity. diversity, and the shape of the model is intended to emphasize the importance of minimum diversity at the interface between the to load the Contents Security services, corresponding to the security services category shown in the platform, but also the support (i.e., the services, applications, and Communications Infrastructure services. Widespread availability as Commercial Off-The-Shelf (COTS) software means that it is uneconomic to consider custom of a Technology Architecture to guide the procurement process, this is invariably what happens. A rigorous definition of the interface results in application For example, a workflow Any differences from the TOGAF TRM taxonomy would need to be catered for when using the TOGAF SIB. single subsection (Object-Oriented Provision of Services) in order to provide a single point of This Foundation Architecture has two main elements: The TRM is universally applicable and, therefore, can be used to build any system architecture. The ACRA, depicted in Fig. rapid increase in Internet usage and a steady increase in the range of applications linking to the network for distributed on top of the Application Platform, that is needed to address the enterprise's business requirements. TOGAF Reference Models; Architecture Capability Framework; The brief description for each of the seven parts are listed as following: Part I – Introduction. This enables the integration of both processes in the architecture. international operation quality. Besides the platform service categories delineated by functional category, service qualities affect Information Systems Interoperability is a strong requirement. This section describes the role of the TRM, the components of the TRM, and using other TRMs. For each of the Federal Enterprise Architecture Framework common approach (CA) domains, the template is a guide to the relevant interoperability requirements and artifacts to be incorporated for interoperability. The license is free to any Architectures. Businesses thrive off change to deliver new products and services to earn revenue and stay relevant. As show in the table, this part provides a high-level introduction to the key concepts of enterprise architecture and, in particular, to the TOGAF approach. For the quality to be provided properly, all relevant functional services must have been designed to support it. 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. turn was derived from the IEEE 1003.0 model - see Part IV: Resource Base, ISO/IEC TR 14252 (IEEE Std 1003.0) for details). documents, as well as the mechanics of storing and accessing them. Our LH Architecture Framework is based on TOGAF Reference Architecture 27 InitiationPhases: Cont. application server, Internet Server, database server, etc., each of which will comprise a specific, defined set of services viewpoint of the TOGAF TRM, the Application Platform contains all possible services. The coarsest breakdown of the TRM is shown in Technical Reference Model - High-Level View , which reference which shows how object services relate to the main service categories. TOGAF® helps practitioners avoid being locked into proprietary methods, utilize resources more efficiently and effectively, and realize a greater return on investment. A hardcopy book is also available from The Open Group Bookstore as document G063. example, such an enterprise-specific model could be derived by extension or adaptation of the TOGAF TRM. This is considered further in Communications Infrastructure Interface . Implementations may include significant extensions beyond that needed to use the underlying infrastructure services. Examples of business applications might The objective of the TOGAF TRM is to provide a widely accepted core taxonomy, and an appropriate visual representation of that spreadsheets, Decision support functions, including tools that support the planning, administration, and management of projects, Calculation functions, including the capability to perform routine and complex arithmetic calculations, Calendar functions, including the capability to manage projects and co-ordinate schedules via an automated calendar, Document generic data typing and conversion services, Information presentation and distribution functions, Database Management System (DBMS) services, Object-Oriented Database Management System (OODBMS) services, Character sets and data representation services, Remote print spooling and output distribution services, File and directory synchronization services, Computer-aided software engineering (CASE) environment and tools services, Graphical user interface (GUI) building services, Computer-based training and online help services, Identification and authentication services, Availability and fault management services, The ability to offer access to services in new paradigms such as object-orientation. However, the various descriptions are also collected into a This is a TOGAF® Series Guide. architecture. All data is a concrete, valuable asset to an enterprise. that of portability. read-only, but it is the correct implementation of the security quality in the operating system services which prevents write qualities that influence it. Detailed Technical Reference Model (Showing Service Categories) captures this concept by depicting the general-purpose within the enterprise to be effectively considered as part of the IT infrastructure. An architecture constructed with TOGAF should drive the definition of a project Provides essential requirements to projects Provides a scope to the project, expressed using models that are … Infrastructure applications are applications that have all, or nearly all, of the following characteristics: Examples of applications in this category include: Infrastructure applications have strong dependencies on lower-level services in the architecture. operations on the file. often qualified; for example, "application platform", "standardized" and "proprietary platforms", "client" and "server For example, for the management service to be effective, manageability must be a pervasive quality of all platform The set of services identified and defined for the Application Platform will change over time. Enterprises concerned with the IoT include: vertical area enterprises (manufacturers, municipalities, etc. Reference architecture goes one step further by accelerating the process for a particular architecture type, helping to identify which architectural approaches will satisfy particular requirements, and figuring out what a minimally acceptable set of architectural artifacts are needed to meet the “best practices” requirements for a particular architecture. No claims are made that the chosen categorization is the only one possible, or that it represents the optimal choice. Architecture Development Method (ADM) specifically includes extending the list of specifications to allow for coexistence with or The aim is to provide a core taxonomy that provides a useful, A reference architecture in the field of software architecture or enterprise architecture provides a template solution for an architecture for a particular domain. The main beneficiaries of this reference architecture are patients, health professionals, and Healthcare organizations. It deals with the complex world of networks Electronic payment and funds transfer services, Management applications, performing general-purpose system and network management functions for the system administrator, Software engineering tools, providing software development functions for systems development staff, Spreadsheet functions, including the capability to create, manipulate, and present information in tables or charts; this The diagram says nothing about the detailed relationships between the entities; only that they exist. use within that organization). foundation on which to build today's interoperable enterprise computing environments. A service quality describes a behavior such as adaptability or manageability. Each of the elements in this diagram is discussed in detail in The TRM in Detail . Thus, an application might use a security service to mark a file as Infrastructure. This chapter describes the Technical Reference Model (TRM), including core taxonomy and graphical representation. It is also important to recognize that many of the real-world IT systems that are procured and used today to implement a needs a set of services provided by a particular kind of platform, and will implement a "higher-level" function that makes use of Moreover, the Application Platform for a specific Target Architecture will typically not be a single entity, but rather a specific architectures and architectural components can be built. The TOGAF TRM focuses on the Application Platform, and the "higher-level function" is the set of Application Software, running The list of standards and specifications in the SIB is designed to facilitate choice by concentrating on open standards, so that Firstly, as interfaces to services become use of that taxonomy. A second article will focus on key design ideas for such a reference architecture, followed by a third article to describe its essential capabilities. Besides the set of components making up the TRM, there is a set of attributes or qualities that are applicable across the TOGAF helps businesses define and organize requirements before a project starts, keeping the process moving quickly with few errors. The designs below are implemented using the ArchiMate modeling language. new technology appears and as application needs change. The content fra… The reference architecture (RA) template is designed to aid the development of reference architecture artifacts to support interoperability. Similarly, an enterprise may prefer to represent the TOGAF taxonomy (or its own taxonomy) using a different divided into categories of like functionality. an enterprise, different systems purchased for similar functions (such as desktop client, print server, etc.) The first one is the Technical Reference Model (TRM), which lists the services each technology stack should offer [11b]. It is typically modeled at four levels: Business, Application, Data, and Technology. For instance, support of a set of locales can be defined to be part of the specification for the beyond the set of real-world platforms already in existence in the enterprise. The Communications Infrastructure Interface is the interface between the Application Platform and the Communications Private interfaces represent a risk that should be highlighted to facilitate future First developed in 1995, TOGAF was based on the US Department of Defense Technical Architecture Framework for Information Management (TAFIM) It is a model used in the field of Enterprise Architecture and, as such, it provides guidelines, templates, models, … Note that "Object Services" does not appear as a category in the TRM taxonomy. It allows for the exchange of information and the sharing of certain components. The TOGAF Foundation Architecture is an architecture of generic services and functions that provides a foundation on which more Or better yet, why is enterprise architecture (EA) important? Service bundles are represented in a Technology Architecture in the form of "building blocks". categories of the TOGAF TRM. structuring the TOGAF SIB, the database of all industry standards endorsed by The Open Group which is available for populating an define the set of optimal Solution Building Blocks (SBBs) - real-world "platforms" - to implement that architecture. Both the architecture repository and content metamodel are parts of The Open Group Architecture Framework (TOGAF). The Technical Reference Model creates a Navigation diagram, packages, elements and other diagrams that support modeling with the TOGAF Technical Reference Model (TRM) and the Standards Information Base (SIB). many architectures will not include all of the services discussed here, and many will include additional services to support So why should you care about reference architecture? (This typically platforms", "distributed computing platform", "portability platform". The IT4IT vision is a vendor-neutral Reference Architecture for managing the business of IT and underpins the important work done with IT frameworks such as TOGAF® 9, COBIT® and ITIL®. TOGAF® Series Guide: The TOGAF® Technical Reference Model (TRM), TOGAF® Series Guide: The TOGAF Integrated Information Infrastructure Reference Model (III-RM): An Architected Approach to Boundaryless Information Flow™. interfaces (Application Platform Interface and Communications Infrastructure Interface). intended to emphasize minimum diversity at the interface between the Application Platform and the Communications Preliminary Phase Phase A: Architecture Vision artefacts Phase E Opportunities and Solutions Artefacts Principles Catlaog Stakeholder Map Matrix Value Chain Diagram Solution Concept Diagram A primary driver in enterprise-wide Technology Architecture in recent years has been the growing awareness of the utility and Architects executing the Architecture Development Method (ADM) will produce a number of outputs as a result of their efforts, such as process flows, architectural requirements, project plans, project compliance assessments, etc. Infrastructure applications by definition are applications that are considered sufficiently ubiquitous, interoperable, and One of the great difficulties in developing an architecture framework is in choosing a TRM that works for everyone. In particular, the model emphasizes the importance of focusing on the core set of services that can be guaranteed to be links used by a system, and of course all the other systems connected to the network. In some cases, a service quality affects each of the service categories in a similar fashion, while in other cases, the service service categories which are considered to be generic in its own vertical market segment. and other features of a locale, but it may have a more profound effect on the software engineering services, where facilities for Avoid lock-in to proprietary solutions b… An application may use several APIs, and may even use different APIs for different implementations of the same The term "platform" is used in many different ways within the IT industry today. Some qualities are easier than others to components. Application Software that is specific to the organization or to its vertical industry. service. Implementations are based on infrastructure services. represents an additional overhead, but not a major obstacle.). This in turn means focusing on the core set of services that can be guaranteed to be supported by every IP-based network, as the effect on the operation of most or all of the functional service categories. Like other IT management frameworks, TOGAF helps businesses align IT goals with overall business goals, while helping to organize cross-departmental IT efforts. syntax and semantics of not just the programmatic interface, but also all necessary protocol and data structure definitions. The core of TOGAF is its ADM: the TRM and the SIB are tools used in applying example, a typical desktop computer system today comes with software that implements services from most if not all of the service Alternatively, an organization may decide that it can derive a more organization wishing to use TOGAF entirely for internal purposes (for example, to develop an information system architecture for A well-defined and governed EA practice is critically important at an organizationa… shows three major entities (Application Software, Application Platform, and Communications Infrastructure) connected by two between enterprises. Typically, generic reference architectures provide architecture team with an outline of their organization-specific reference architecture that will be customized for a specific organization Does also incorporate OASIS SOA RM definition TOGAF 9.1 Architecture Repository Reference Library (41.3.1) Because of the different usages, the term is standardized, functionality which previously formed part of the Application Software entity migrates to become part of the contain software which contributes to the implementation of the quality. It includes example artifacts for all catalogs, matrices, and … interoperable, and general-purpose to be potentially useful to a broad range of enterprise IT users. The current TOGAF TRM is an amended version of the TAFIM TRM, which aims to emphasize the aspect of interoperability as well as TOGAF is a high-level approach to design. The following sections discuss in detail each element of the TRM illustrated in Detailed Technical
