•   Chapter 5 provides an introduction to the Architecture Content Framework, a structured metamodel for architectural artifacts

•   Chapter 6 provides an introduction to the Enterprise Continuum, a high-level concept that can be used with the ADM to develop an Enterprise Architecture

•   Chapter 7 provides an introduction to the Architecture Capability Framework, a set of resources provided for establishment and operation of an architecture function within an enterprise

•   Appendix A provides an overview of the changes between Version 9.1 and Version 9.2 of the TOGAF standard

The audience for this document is:

•   Enterprise Architects, Business Architects, IT architects, data architects, systems architects, solutions architects, and senior managers seeking a first introduction to the TOGAF standard

About the TOGAF Standard, Version 9.2

The TOGAF Standard, Version 9.2 is an update to the TOGAF 9.1 Standard providing improved guidance, correcting errors, improving the document structure, and removing obsolete content. Key enhancements made in this version include updates to the Business Architecture and the Content Metamodel. All of these changes make the TOGAF framework easier to use and maintain. It retains the major features and structure of the TOGAF 9.1 Standard including:

Modular Structure: The TOGAF standard has a modular structure. The modular structure supports:

•   Greater usability – defined purpose for each part; can be used in isolation as a standalone set of guidelines

•   Incremental adoption of the TOGAF standard

•   Accompanying the standard is a portfolio of guidance material, known as the TOGAF Library, to support the practical application of the TOGAF approach

Content Framework: The TOGAF standard includes a content framework to drive greater consistency in the outputs that are created when following the Architecture Development Method (ADM). The TOGAF content framework provides a detailed model of architectural work products.

Extended Guidance: The TOGAF standard features an extended set of concepts and guidelines to support the establishment of an integrated hierarchy of architectures being developed by teams within larger organizations that operate within an overarching architectural governance model. In particular, the following concepts are included:

•   Partitioning – a number of techniques and considerations on how to partition the various architectures within an enterprise

•   Architecture Repository – a logical information model for an Architecture Repository which can be used as an integrated store for all outputs created by executing the ADM

•   Capability Framework – a structured definition of the organization, skills, roles, and responsibilities required to operate an effective Enterprise Architecture Capability; the TOGAF Standard also provides guidance on a process that can be followed to identify and establish an appropriate Architecture Capability

Architectural Styles: The TOGAF standard is designed to be flexible and it can be used with various architectural styles. Examples are provided both in the TOGAF standard, in Part III: ADM Guidelines and Techniques, and in the TOGAF Library. Together these comprise a set of supporting materials that show in detail how the ADM can be applied to specific situations; for example:

•   The varying uses of iteration that are possible within the ADM and when each technique should be applied

•   The various types of architecture development required within an enterprise and how these relate to one another

•   The use of the TOGAF ADM with Service-Oriented Architectures (SOAs), Risk and Security, etc.

Additional ADM Detail: The TOGAF Standard, Version 9.2 includes additional detailed information over earlier versions of the TOGAF Standard for supporting the execution of the ADM. Particular areas of enhancement are:

•   The Architecture Vision and Business Architecture phases feature extended guidance on development of the Business Architecture; this includes focus on Business Capabilities, Value Streams, and Organization Maps

•   The Technology Architecture phase recognizes that emerging technologies are increasingly leading to technology-driven change
