Pictures That Describe What TOGAF Is

Today´s post is provides an overview of what TOGAF is and what it stands for. It does so with a short series of pictures which each address an important aspect of TOGAF.

TOGAF Timeline / History

TOGAF was first published in 1995 by The Open Group. Since then, new versions have been released every few years. In the recent past, the frequency of new releases has lowered. The latest version of TOGAF, which is version 9.2, was released in 2018.

The TOGAF ADM

The TOGAF Architecture Development Method provides a stepwise approach to architecture development projects. While the method itself is fixed phases, The Open Group clearly emphasizes that it can be used in different agile contexts and it provides several possibilities of how an architecture project can cycle through the different phases and repeat them depending on the need and maturity of the output.

The TOGAF Architecture Layers

The TOGAF Architecture layers build today´s basis for many architectural approaches and ways of thinking. The layers that TOGAF provides are rather simplistic and limited to 3 main layers, which are the business layer, information systems layer, and the technology layer. In addition, the information systems layer has two sub-layers, which are the applications layer and the data layer. Today´s enterprise architecture best practices usually amend the TOGAF layers by additional layers or put more emphasis on particular aspects.

TOGAF Content Metamodel

The TOGAF content metamodel provides a model to sort different enterprise architecture outputs into a broader model. Just as the ADM, it build on the TOGAF architecture layers and adds a more visionary and strategic category on top, as well as a more operational and realizing category at the bottom to it.

TOGAF Enterprise Continuum

The Enterprise Continuum is a concept to determine the reusability of an enterprise architecture artifact of general output. It is a scale on which generic and reusable artifacts are placed on the left side, while very specific and non-reusable artifacts would be placed on the right side. It is not a real and tangible file ordering system, but is rather meant to explain what type of artifacts can exist and if a reusage would be possible.

TOGAF Views and Viewpoints

In the context of artifacts and enterprise architecture work, TOGAF talks often about views and viewpoints.  While an artifact provides a particular view on something, a viewpoint is a generic position from which something can be looked at. For example, one could develop an application architecture view from its Marketing domain and another application architecture view from its Sales domain. While both artifacts would have the same viewpoint – which is the application architecture – each artifact would provide a different view.

Why Enterprise Architecture?

Enterprise Architecture concept has been introduced since 1960 by Zachman. Although it is still not widely introduced for many organizations, It becomes an important topic in Information Technology community and many organizations are trying to understand how it is important to have Enterprise Architecture capability within the organization.

In this article, I will try to illustrate what is…

Enterprise Architecture: Footing and Efformation Tools

Cartel Local color is the way to push forward business function by implementing subject solutions having best strategies that drives its amplification. It is used in contemplation of increase the effectiveness anent the firm, hardening and agility creating a unified view pertaining to the firm strategic bluffing and effectively formulating the cool architectures such as business, application, information, technology architecture fundamental to target the proposed vision. This conformation helps in organizing the firm's high tax bracket towards achieving the duties and responsibilities objectives. Framework and Tools<\p>

Many frameworks are used by leading companies so as to organise their pecuniary resources. The inter se used among those are Zachman framework and The Receptive Group English Framework (TOGAF). Techniques and strategies requisite headed for order and organize the organisations resources are specified herewith these frameworks. To apprehend and feature the architectural design in a centralized repository, Enterprise Architecture modeling tools are used to which helps up to share and socialize the gambit with the exhaustiveness team. Enterprise Operator from Sparx Systems offers handiwork solutions supporting firms around the world to strategize, systemize and synergize their long strings goals and objectives.<\p>

Zachman Framework This point of view has a strong times past of helping enterprises to compare, organise and structure their principal. Sparx Systems Zachman place supports viewpoints of the organisation, Zachman framework structures with more classical pitch, breath and modeling Integrity. Business Process Analysis and Software Engineering capabilities which are red-blooded feature apropos of Sparx Systems Enterprise Architect when copulate with this framework provides overall solution to kantian idea and maintain the organization's total ALTERUM infrastructure in a single shared storeroom. Benefits of Zachman framework are: Firm's objectives can be strategized and integrated let alone Information Art infrastructure using powerful framework. Provides end-to-end traceability from strategic business goals to final solutions which helps to fix business with IT. Hand trace simplified in favor of visual models and open standards can be easily understood by non-IT people. Documenting extensive enterprise binary digit architectures with an integrated, scalable approach.<\p>

TOGAF in a nutshell

TOGAF is an Enterprise Architecture Framework. It is focusedon Strategic Planning, Execution, Governance of an IT Vision and coming up with a roadmap for Technology Transformation.

Preliminary Phase

Select the Architecture Framework TOGAF TRM or III-RM this forms the basis of the foundation architecture. Next establish Architecture Principles. Business, Data, Application and Technology Principles should be established. The principles should be robust, consistent and stable. An example set of Data Principles: - i. Data is an Asset, Data is Shared, Data is Accessible.

Architecture Vision The Architecture Vision is the elevator pitch statement that could sell the proposed development to stakeholders.

Eg:- 1. Improve the Return on Capital Deployed, Increase Operating Efficiency, Improve the Quality of Service Level across the Technology Landscape. Business Architecture Describe the Baseline (As-Is) and Target (To-Be) Business Architecture. The Architecture could be tabulated as BPMN Models, UML Use Case diagrams. Information Systems Architecture Describe the Baseline (As-Is) and Target (To-Be) Application Architecture, and describe the Baseline (As-Is) and Target (To-Be) Data Architecture. These would consist diagrams for Application Eg:- Portfolio Catalog, Interface Catalog and for Data Eg:- Conceptual and Logical Diagrams, Data Migration Diagram, Data Life Cycle Diagram to name a few.

Technology Architecture

Describe the Baseline (As-Is) and Target (To-Be) Technology Architecture, Environment Location Diagram, Platform Decomposition Diagram are some of the Artefacts produced from this exercise.

Opportunities and Solutions Perform gap analysis and arrive at solutions. You may choose to build a new system, obtain a COTS product or Decommission and existing system. A new system would be represented by a Solution Buiding Block, while existing systems would be ABBs (Architecture Building Blocks). Migration Planning Plan the migration from the Baseline to Target Architecture (Business, Data, Application and Technology) and produce a detailed Implementation Plan and Migration Plan.

Implementation Governance The information for management of various development projects is brought together.

Architecture Change Management Continual monitoring of environment for changes. Ensure changes to the architecture are managed in a cohesive manner. New Requests for Architecture work are created as required. What is an Architecture Viewpoint ? TOGAF documentation for Data Architecture a Planner would require a Data Entity View, the Designer would need Logical Data View, Standards View, System Engineering View the Builder would need Physical Data View. TOGAF provides a set of Catalogs and Diagrams to address different viewpoints.
