8. Enterprise Architecture approach - TOGAF v9There are seven main parts to the TOGAF document:PART I (Introduction) This part provides a high-level introduction to the key concepts of enterprise architecture and in particular the TOGAF approach. It contains the definitions of terms used throughout TOGAF and release notes detailing the changes between this version and the previous version of TOGAFPART II (Architecture Development Method) This part is the core of TOGAF. It describes the TOGAF Architecture Development Method (ADM) - a step-by-step approach to developing an enterprise architecturePART III (ADM Guidelines and Techniques) This part contains a collection of guidelines and techniques available for use in applying TOGAF and the TOGAF ADMPART IV (Architecture Content Framework) This part describes the TOGAF content framework, including a structured metamodel for architectural artifacts, the use of re-usable architecture building blocks, and an overview of typical architecture deliverablesPART V (Enterprise Continuum & Tools) This part discusses appropriate taxonomies and tools to categorize and store the outputs of architecture activity within an enterprisePART VI (TOGAF Reference Models) This part provides a selection of architectural reference models, which includes the TOGAF Foundation Architecture, and the Integrated Information Infrastructure Reference Model (III-RM)PART VII (Architecture Capability Framework) This part discusses the organization, processes, skills, roles, and responsibilities required to establish and operate an architecture function within an enterpriseThe intention of dividing the TOGAF specification into these independent parts is to allow for different areas of specialization to be considered in detail and potentially addressed in isolation. Although all parts work together as a whole, it is also feasible to select particular parts for adoption whilst excluding others. For example, an organization may wish to adopt the ADM process, but elect not to use any of the materials relating to architecture capability.
