TOGAF

Enterprise Architecture approach - TOGAF v9There are seven main parts to the TOGAF document:

1. 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

2. 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

3. 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

4. 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

5. PART V (Enterprise Continuum & Tools) This part discusses appropriate taxonomies and tools to categorize and store the outputs of architecture activity within an enterprise

6. 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)

7. 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

Part I – Overview of EA Methods

Zachman

There are six domains to the Zachman Framework:

1. Data - What

2. Function - How

3. Network - Where

4. People - Who

5. Time - When

6. Motivation - Why

There are five roles mapped to the six domains in the Zachman Framework:

1. Planner - Scope - Contextual

2. Owner - Business Model - Conceptual

3. Designer - System Model - Logical

4. Builder - Technology Model - Physical

5. Sub-Contractor - Detailed Representations – Out-of-context

Part I – What EA Addresses

• Technology and Business Strategy

• Roadmap alignment

• Standardization

• Future-proofing

Part I – Role for Technology Change

IT analyzes and recommends best solutions based on business needs

• ROI• Least COST• Grow Revenue• Contain costs• Outsource• Buy vs. Lease• COTS vs Opensource

Part I – Role for Business Change

EA provides a bridge for Business and IT alignment

• executive decision support• guiding principles• technology usage and guidance• idea generation by usage and enablement• collaboration
