    • Part I – Overview of EA Methods
      TOGAF
    • Enterprise Architecture approach - TOGAF v9
      There 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 TOGAF
      PART 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 architecture
      PART III (ADM Guidelines and Techniques) This part contains a collection of guidelines and techniques available for use in applying TOGAF and the TOGAF ADM
      PART 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 deliverables
      PART V (Enterprise Continuum & Tools) This part discusses appropriate taxonomies and tools to categorize and store the outputs of architecture activity within an enterprise
      PART 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 enterprise
      The 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.

    • Part I – Overview of EA Methods
      There are six domains to the Zachman Framework:
      Data - What
      Function - How
      Network - Where
      People - Who
      Time - When
      Motivation - Why
      Zachman
      There are five roles mapped to the six domains in the Zachman Framework:
      Planner - Scope - Contextual
      Owner - Business Model - Conceptual
      Designer - System Model - Logical
      Builder - Technology Model - Physical
      Sub-Contractor - Detailed Representations – Out-of-context
